Start/Stop* - function and operation

The Start/Stop function is activated automati-
cally when the engine is started with the key.

The Start/Stop function is acti-
vated automatically when the
engine is started with the key.
The driver is made aware of the
function by the function's
On/Off button symbol lighting
up in the combined instrument
panel and the On/Off button
lamp illuminating.

All of the car's normal systems

such as lighting, radio, etc. work as normal even
with an engine that has stopped automatically,
except that some equipment may have the func-
tion temporarily reduced, e.g. the climate control
system's fan speed or extremely high volume on
the audio system.

Auto-stopping the engine

The following is required for the engine to auto-
stop:

STARTING AND DRIVING

280

Conditions

M/A

Declutch, set the gear lever in neutral
position and release the clutch pedal -
the engine stops automatically.

Stop the car with the foot brake and
then keep your foot on the pedal - the
engine stops automatically.

M = Manual gearbox, A = Automatic gearbox.

If the ECO function is activated
then the engine may auto-stop
before the car is completely
stationary.

For certain engine variants the engine may auto-
stop before the car is stationary regardless of
whether the ECO function is activated.

When the engine is auto-stopped, the
combined instrument panel's symbol
for the Start/Stop function illuminates.

Auto-starting the engine

Conditions

M/A

With the gear lever in neutral position:

1. Depress the clutch pedal or press

the accelerator pedal - the engine
starts.

2. Engage a suitable gear and drive.

Release the foot pressure on the foot
brake - the engine starts automatically
and the journey can continue.

Maintain foot pressure on the foot
brake and depress the accelerator
pedal - the engine auto-starts.

The following option is also available on
a downhill gradient:

•

Release the foot brake and let the
car move off - the engine starts
automatically when the speed
exceeds normal walking pace.

M +

M = Manual gearbox, A = Automatic gearbox.

Deactivating the Start/Stop function

In certain situations, it may
advisable to temporarily switch
off the automatic Start/Stop
function - this is carried out
with a push of this button.

Disengaged function is indicated by
the combined instrument panel's
Start/Stop symbols and the button's
lamp extinguishing.

The Start/Stop function is disengaged until it is
reactivated with the button or until the next time
the engine is started with the key.

Start assistance HSA

The foot brake can also be released on an uphill
slope to auto-start the engine - the HSA (p. 278)
(Hill Start Assist) function prevents the car from
rolling backwards.

HSA means that the pressure in the brake sys-
tem remains temporarily available while the driv-
er's foot is moved from the brake pedal to the
accelerator pedal for driving off with the engine
having stopped automatically. The temporary
braking effect releases after a couple of seconds
or when the driver accelerates.

Drive mode ECO*

ECO

is an innovative Volvo function for auto-

matic-gearbox cars, capable of reducing fuel
consumption by up to 5%, depending on the
driver's driving style. The function gives the driver
the option of a more active environmentally con-
scious way of driving.

General

The following are changed
upon activation of the ECO
function:

•

Gearbox gearshift points.

•

Engine management and response from the
accelerator pedal.

•

Start/Stop function - the engine can also
auto-stop before the car has stopped down
to being completely stationary.

•

The Eco Coast function is activated - engine
braking ceases.

•

Climate control system settings - some elec-
tricity consumers are deactivated or operate
at reduced power.

When the ECO function is activated, several
parameters in the climate control system's
settings are changed, and several electricity
consumer functions are reduced. Certain set-
tings can be reset manually, but full function-
ality is only restored by deactivating the ECO
function.

ECO - Operation

ECO On/Off

ECO symbol

The ECO function is deactivated when the engine
is switched off, and must therefore be activated
after each time the engine is started. There are
exceptions for certain engines. However, it is

easily verified by means of both the combined
instrument panel's

ECO

symbol and the ECO-

button's lamp illuminating when the function is
activated.

ECO function On or Off

Disengaged ECO function is
indicated by the combined
instrument panel

ECO

symbol

and the ECO button lamp extin-
guishing. The function is then
switched off until it is reactiva-
ted with the ECO button.

Eco Coast - Function

The Eco Coast subfunction means in practice
that engine braking is deactivated, meaning in
turn that the car's kinetic energy is used to coast
for longer distances. When the driver releases
the accelerator pedal the gearbox is automatically
disengaged from the engine whose speed is
reduced to idling speed with minimum consump-
tion.

This function is intended for use in the event of
an anticipated reduction in speed, e.g. to coast
into a zone with a lower speed limit.

Eco Coast enables proactive driving where the
driver can use the so-called "Pulse & Glide"
technique and a minimum of braking.

Not possible on the V40 CROSS COUNTRY with AWD.

STARTING AND DRIVING

288

A combination of Eco Coast and temporarily
deactivated ECO function can also collectively
contribute to reduced consumption. Accordingly:

•

Active Eco Coast: Long coasting without
engine braking = Low consumption

and

•

Deactivated ECO function: Short coasting
with engine braking = Minimum consump-
tion.

General information on climate control
(p. 126)

However, to achieve optimal low fuel con-
sumption, Eco Coast in combination with
short coasting distances should generally be
avoided.

Activating Eco Coast

The function is activated when the accelerator
pedal is fully released, in combination with the
following parameters:

•

ECO button activated

•

Gear selector in D position

•

Speed within the range of
approx. 65-140 km/h (40-87 mph)

•

The road's downhill gradient is not steeper
than approx. 6%.

Deactivate Eco Coast

In certain situations it may be desirable to deacti-
vate the Eco Coast function. Examples of such
situations include:

•

on steep downhill gradients - to be able to
use engine braking.

•

before an imminent overtaking manoeuvre -
in order to be able to complete it in the saf-
est possible way.

Deactivating Eco Coast and returning to engine
braking can be performed as follows:

•

Press the ECO button.

•

Move the gear lever to manual "S+/-" posi-
tion.

•

Change gear with the steering wheel paddle
shifters.

•

Actuate the accelerator or brake pedal.

Eco Coast - Limitations

The function is not available if:

•

cruise control is activated

•

the road's downhill gradient is steeper than
approx. 6%

•

manual gear changing is performed with the
steering wheel paddle shifters

•

engine and/or gearbox are not at normal
operating temperature

•

the gear selector is moved from D- to "S+/-"
position

•

speed is outside the range of
approx. 65-140 km/h (40-87 mph).

More information and settings

The car's menu system MY CAR contains further
information on the ECO concept - see the sec-
tion MY CAR (p. 113).

Foot brake

The foot brake is part of the brake system.

The car is equipped with two brake circuits. If a
brake circuit is damaged then the brake pedal will
engage deeper and a higher pressure on the
pedal is needed to produce the normal braking
effect.

The driver's brake pedal pressure is assisted by a
brake servo.

WARNING

The brake servo only works when the engine

is running.

If the brake is used when the engine is switched
off then the pedal will feel stiff and more force
must be used to brake the car.

For cars with the Hill start assist (HSA)

* (p. 278)*

function, the pedal returns more slowly than
usual to normal position if the car is parked on a
gradient or on an uneven surface.

In very hilly terrain or when driving with a heavy
load the brakes can be relieved by using engine
braking. Engine braking is most efficiently used if
the same gear is used downhill as up.

For more general information on heavy loads on
the car, Engine oil - adverse driving conditions
(p. 389).

Braking on wet roads

When driving for a long time in heavy rain without
braking, the braking effect may be delayed
slightly when next using the brakes. This may
also be the case after a car wash. It is then nec-
essary to depress the brake harder. For this rea-
son, maintain a greater distance to the traffic
ahead.

Brake the car firmly after driving on wet roads
and after a car wash. The brake discs are then
warmed up, dry more quickly and are protected
against corrosion. Take the prevailing traffic sit-
uation into account when braking.

Braking on salted roads

When driving on salted roads a layer of salt may
form on the brake discs and brake linings. This
may extend braking distance. For this reason,
keep an extra-large safety distance to the vehicle
ahead. Also make sure of the following:

•

Brake occasionally to remove any layer of
salt. Make sure that other road users are not
put at risk by the braking.

•

Gently depress the brake pedal when driving
is finished and before the next journey starts.

Maintenance

To keep the car as safe and reliable as possible,
follow the Volvo service intervals as specified in
the Service and Warranty Booklet.

New and replaced brake linings and brake discs
do not provide optimal braking effect until they
have been "worn in" a few hundred kilometres.
Compensate for the reduced braking effect by
depressing the brake pedal harder. Volvo recom-
mends only fitting brake linings that are approved
for your Volvo.

IMPORTANT

The wear on the brake system's components
must be checked regularly.

Contact a workshop for information about the
procedure or engage a workshop to carry out
the inspection - an authorised Volvo work-
shop is recommended.

Foot brake - anti-lock braking

system

The anti-lock braking system, ABS (Anti-lock
Braking System), prevents the wheels from lock-
ing up during braking.

The function allows the steering ability to be
maintained, and it is easier to swerve to avoid a
hazard for example. Vibration may be felt in the
brake pedal when this is engaged and this is nor-
mal.

A short test of the ABS system is made automat-
ically after the engine has been started when the
driver releases the brake pedal. A further auto-
matic test of the ABS system may be made at
low speed. The test may be experienced as pul-
ses in the brake pedal.

Foot brake - emergency brake lights

and automatic hazard warning

flashers

Emergency brake lights are activated to alert
vehicles behind about heavy braking. The func-
tion means that the brake light flashes instead of
- as in normal braking - shining with a constant
glow.

Emergency brake lights are activated at speeds
above 50 km/h (31 mph) if the ABS system is
working and/or in the event of heavy braking.
After the car's speed has been slowed below
10 km/h (6 mph) the brake light returns from
flashing to the normal constant glow - while at
the same time the hazard warning flashers(p. 99)
are activated, and they flash until the driver accel-
erates the car to at least 20 km/h (12 mph) or
they are deactivated with their button.

Foot brake - emergency brake

assistance

Emergency brake assistance EBA (Emergency
Brake Assist) helps to increase the braking force
and so reduce the braking distance.

EBA detects the driver's braking style and increa-
ses the braking force when necessary. The brake
force can be reinforced up to the level when the
ABS system is engaged. The EBA function is
interrupted when the pressure on the brake pedal
is reduced.

When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.

Parking brake

The parking brake prevents the car from rolling
away from stationary by means of mechanically
locking/blocking two wheels.

WARNING

Always apply the parking brake when parking

on a slope - leaving the car in gear, or in P if it

has automatic transmission, is not sufficient

to hold the car in all situations.

Combined instrument panel warning symbol.

Applying the parking brake

1. Press the foot brake pedal down firmly.

2. Pull the lever firmly.

The combined instrument panel

warning symbol comes on. The warning
symbol illuminates regardless of whether
the parking brake is applied gently or
firmly.

3. Release the foot brake pedal and make sure

that the car is at a standstill position.

4. If the vehicle moves then the parking brake

lever must be applied at least a little more
firmly.

When parking the vehicle, always engage 1st
gear (for manual gearbox) or put the gear selec-
tor in position P (for automatic gearbox).

Parking on a hill

If the car is parked facing uphill:

•

Turn the wheels away from the kerb.

If the car is parked facing downhill:

•

Turn the wheels towards the kerb.

Disengaging the parking brake

1. Press the foot brake pedal down firmly.

2. Pull the lever up slightly, press the button,

release the lever and release the button.
> The combined instrument panel warning

symbol goes off.

If the driver forgets to release the parking brake –
in addition to the illuminated warning lamp – a
pinging sound combined with a message in the

Driving in water

Driving in water means that the car is driven
through deep water on a water-covered road-
way. Fording must be carried out with great cau-
tion.

The car can be driven through water at a maxi-
mum depth of 25 cm at a maximum speed of
walking pace. Extra caution must be exercised
when passing through flowing water.

During driving in water, maintain a low speed and
do not stop the car. When the water has been
passed, depress the brake pedal lightly and
check that full brake function is achieved. Water
and mud for example can make the brake linings
wet resulting in delayed brake function.

•

If necessary, clean the contacts for the elec-
tric heater and trailer coupling after driving in
water and mud.

•

Do not let the car stand with water over the
sills for any long period of time - this could
cause electrical malfunctions.

IMPORTANT

Engine damage can occur if water enters the
air filter.

In depths greater than 25 cm, water could
enter the transmission. This reduces the lubri-
cating ability of the oils and shortens the
service life of these systems.

Damage to any component, engine, transmis-
sion, turbocharger, differential or its internal
components caused by flooding, hydrostatic
locking or oil shortage, is not covered by the
warranty.

In the event of the engine stalling in water, do
not try restart - tow the car from the water to
a workshop - an authorised Volvo workshop is
recommended. Risk of engine breakdown.

Overheating

Under special conditions, for example hard driv-
ing in hilly terrain and hot climate, there is a risk
that the engine and drive system may overheat -
in particular with a heavy load.

For information about overheating when driving
with a trailer, see Driving with a trailer (p. 302).

•

Remove any auxiliary lamps from in front of
the grille when driving in hot climates.

•

If the temperature in the engine's cooling
system is too high then a warning symbol is
illuminated and a text message

is shown in the

combined instrument panel's information dis-
play - stop the car in a safe way and allow
the engine to run at idling speed for several
minutes in order to cool down.

•

If the text message

High engine

Engine

coolant level low Stop safely

is shown

then the engine must be switched off after
stopping the car.

•

In the event of overheating in the gearbox a
built-in protection function is activated, which
is indicated in the combined instrument
panel with a warning symbol and the text
message

Wait for cooling

- follow the recommenda-

tion given and lower the speed and stop the
car in a safe way and allow the engine to run

at idling speed for a few minutes in order to
allow the gearbox to cool down.

•

If the car overheats, the air conditioning may
be switched off temporarily.

•

Do not turn the engine off immediately you
stop after a hard drive.
