Dodge Magnum (2008 year). Instruction

original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use spare
tire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.

WARNING!

The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold tire
inflation pressure listed on either your tire placard or
limited use spare tire and wheel assembly. Replace
(or repair) the original tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.

Tire Spinning

When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping when you are stuck.

Refer to “Freeing A Stuck Vehicle” in Section 6 of this
instruction for additional information.

WARNING!

Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than 30
mph (48 km/h) or for more than 30 seconds continu-
ously when you are stuck, and don’t let anyone near
a spinning wheel, no matter what the speed.

STARTING AND OPERATING

Tread Wear Indicators

Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.

Many states have laws requiring tire replacement at this
point.

Life of Tire

The service life of a tire is dependent upon varying
factors including but not limited to:

• Driving style
• Tire pressure
• Distance driven

STARTING AND OPERATING

317

WARNING!

Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.

Replacement Tires

The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.

318

STARTING AND OPERATING

WARNING!

• Do not use a tire, wheel size or rating other than

that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have an accident resulting in serious injury
or death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.

• Never use a tire with a smaller load index or

capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.

• Failure to equip your vehicle with tires having

adequate speed capability can result in sudden
tire failure and loss of vehicle control.

CAUTION!

Replacing original tires with tires of a different size may
result in false speedometer and odometer readings.

Alignment And Balance

Poor suspension alignment may result in:
• Fast tire wear.
• Uneven tire wear, such as feathering and one-sided

wear.

• Vehicle pull to right or left.

Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.

STARTING AND OPERATING

319

SELF-SEALING TIRES — IF EQUIPPED

A non-hardening viscous sealant applied to the inner
liner of each tire fills punctures up to 0.19 in. (5 mm) to
minimize the loss of air pressure. This contributes to the
safety of the vehicle by significantly reducing the prob-
ability of a roadside stop due to a flat tire.

TIRE CHAINS

Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer. In addition, only install tire chains on
P215/65 R17 and P225/60 R18 size tires. The P245/45
R20 size tires do not provide adequate clearance for tire
chains.

NOTE:

Do not use tire chains on a compact spare tire.

CAUTION!

To avoid damage to your vehicle or tires, observe the follow-
ing precautions:
• Because of restricted chain clearance between tires and

other suspension components, it is important that only
chains in good condition are used. Broken chains can
cause serious damage. Stop the vehicle immediately if
noise occurs that could indicate chain breakage. Remove
the damaged parts of the chain before further use.

• Install chains on the rear wheels as tightly as possible and

then retighten after driving about

⁄

mile (0.8 km).

• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large bumps,

especially with a loaded vehicle.

• Use on Rear Wheels only.
• Do not drive for prolonged period on dry pavement.
• Observe the tire chain manufacturer’s instructions on the

method of installation, operating speed, and conditions
for use. Always use the lower suggested operating speed
of the chain manufacturer if different from the speed
recommended by the manufacture.

320

STARTING AND OPERATING

NOTE:

In order to avoid damage to tires, chains, and

your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer’s
instructions on method of installation, operating speed,
and conditions for usage.

Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.

SNOW TIRES

Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire sidewall.

If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.

Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph (120
km/h).

TIRE ROTATION RECOMMENDATIONS

Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates, and tend to develop irregular wear pat-
terns.

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.

Follow the “Maintenance Schedule” in Section 8 of this
instruction for the recommended tire rotation frequency.

STARTING AND OPERATING

321

Remember, more frequent rotation is permissible if de-
sired. Also, correct for anything causing rapid or unusual
wear prior to performing the tire rotation.

The suggested rotation method is the “forward-cross”
shown in the following diagram.

TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF
EQUIPPED

• The Tire Pressure Monitor System (TPMS) will warn

the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.

• The tire pressure will vary with temperature by about

1 psi (6.9 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least 3 hours, or driven less than 1 mile (1 km)
after a 3 hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure
molded into the tire sidewall. Refer to the “Tires –
General Information” in this section for information
on how to properly inflate the vehicle’s tires. The tire

322

STARTING AND OPERATING

pressure will also increase as the vehicle is driven - this
is normal and there should be no adjustment for this
increased pressure.

• The TPM System will warn the driver of a low tire

pressure if the tire pressure falls below the low-
pressure warning limit for any reason, including low
temperature effects and natural pressure loss through
the tire.

• The TPM System will continue to warn the driver of

low tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
the recommended cold placard pressure. Once the low
tire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the Tire Pressure Monitoring Telltale Light to
turn off. The system will automatically update and the
Tire Pressure Monitoring Telltale Light will turn off

once the system receives the updated tire pressures.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (25 km/h) in order for the TPMS to
receive this information.

− For example, your vehicle may have a recom-

mended cold (parked for more than 3 hours) placard
pressure of 30 psi (207 kPa). If the ambient tempera-
ture is 68°F (20°C) and the measured tire pressure is
27 psi (186 kPa), a temperature drop to 20°F (-7°C)
will decrease the tire pressure to approximately 26
psi (179 kPa). This tire pressure is sufficiently low
enough to turn ON the Tire Pressure Monitoring
Telltale light. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa),
but the Tire Pressure Monitoring Telltale Light will
still be ON. In this situation, the Tire Pressure
Monitoring Telltale Light will turn OFF only after
the tires are inflated to the vehicle’s recommended
cold placard pressure value.

STARTING AND OPERATING

323

CAUTION!

• The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.

• After inspecting or adjusting the tire pressure,

always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.

NOTE:

• The TPMS is not intended to replace normal tire care

and maintenance, or to provide warning of a tire
failure or condition.

• The TPMS should not be used as a tire pressure gauge

while adjusting your tire pressure.

• Driving on a significantly under-inflated tire causes

the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

• The TPMS is not a substitute for proper tire mainte-

nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale light.

324

STARTING AND OPERATING

• Seasonal temperature changes will affect tire pressure,

and the TPMS will monitor the actual tire pressure in
the tire.

Base System — If Equipped

The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.

NOTE:

It is particularly important for you to check the

tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.

The TPMS consists of the following components:

• Receiver Module
• 4 Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light

The matching full size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full size spare when it is used in place of a road tire.
Otherwise, a spare with a pressure below the low-
pressure limit will not cause the Tire Pressure Monitoring
Telltale Light to illuminate or the chime to sound.

Tire Pressure Monitoring Low Pressure Warnings

The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or

more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. Once the system receives the updated tire pres-
sures, the system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off. The

STARTING AND OPERATING

325

vehicle may need to be driven for up to 10 minutes above
15 mph (25 km/h) in order for the TPMS to receive this
information.

Check TPMS Warning
If a system fault is detected, the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The Tire
Pressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
due to any of the following:

1. Signal interference due to electronic devices or driving
next to facilities emitting the same Radio Frequencies as
the TPM sensors.

2. Installing aftermarket window tinting that contains
materials, which may block radio wave signals.

3. Accumulation of snow or ice around the wheels or
wheel housings.

4. Using tire chains on the vehicle.

5. Using wheels/tires not equipped with TPM sensors.

NOTE:

Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be moni-
tored by the TPMS.
2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound and
the TPM Telltale Light will turn ON.
3. Driving the vehicle for up to 10 minutes above 15 mph
(25 km/h) will turn off the TPM Telltale Light, as long as
no tire pressure is below the low-pressure warning limit
in any of the four active road tires.

326

STARTING AND OPERATING

NOTE:

Vehicles with Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will turn ON.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPM Telltale Light will flash on and
off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPM Telltale
Light will turn OFF, as long as no tire pressure is below

the low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.

Premium System — If Equipped

NOTE:

It is particularly important for you to check the

tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.

The TPMS consists of the following components:

• Tire Pressure Monitoring Telltale Light

The matching full size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The full
size spare can be used in place of any of the four road
tires. A spare with a pressure below the low-pressure
limit will not cause the Tire Pressure Monitoring Telltale
Light to illuminate or the chime to sound.

Tire Pressure Monitoring Low Pressure Warnings

The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or

more of the four active road tires. In addition, the

Electronic Vehicle Information Center (EVIC) will display
one or more Low Pressure messages (Left Front, Left
Rear, Right Front, Right Rear) for 3 seconds and a graphic
showing the pressure values of each tire with the low tire
pressure values flashing.

328

STARTING AND OPERATING

Should this occur, you should stop as soon as possible,
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the Tire Pressure Monitoring Telltale Light will
turn off. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
