Checking and Topping up

CHECK ENGINE OIL LEVEL

The oil consumption of your engine is 
influenced by many factors: new engines 
reach the normal value only after 
approximately 5 000 km (3 000 miles). 
Under high loads your engine will also 
consume more oil.

Check the oil level regularly with the 
vehicle on flat, level ground.

Refer to pages 187, 188 for dipstick and 
oil filler locations.

It is preferable to check the oil level after 
the vehicle has been standing; that is, 
with the engine completely cold.

If the engine has been started, do not 
check the oil level until the engine has 
reached normal operating temperature. 
Stop the engine and wait for a minimum of 
five minutes to allow the oil to drain back 
into the sump.

Caution: Do not use oil additives of any 
type. Use only specified lubricants.

Gasoline engine oil level

Remove the dipstick (1) and wipe clean 
with a lint free cloth. Replace fully, then 
withdraw the dipstick. If the oil level is 
above the lower of the two dots on the 
dipstick then no additional oil is required.

If the oil level reaches the lower of the two 
dots, remove the oil filler cap (2) and add 
oil, to the quantity and specification 
shown in RECOMMENDED ENGINE OIL 
on page 190.

Refit the dipstick and filler cap and 
securely tighten the filler cap by hand.

RECOMMENDED ENGINE OIL

Jaguar recommends

When the oil level is at the lower dipstick 
mark, add 1litre (1.1 US quart) of oil.

Oil specification – Gasoline engine

API SL/EC and ILSAC GF-3.

When topping up between 
oil changes, make sure that 
you use oil that has the 
correct quality level (API 

service) and viscosity grade.

Caution: Your vehicle’s warranty may 
be invalidated if damage is caused by 
use of improper engine oil. Low quality 
or obsolete oils do NOT provide the 
protection required by modern, high 
performance engines.

Failure to use an oil that meets the 
required specification could cause 
excessive engine wear, a build up of 
sludge and deposits, and increase 
pollution. It could also lead to engine 
failure.

SAE VISCOSITY RATING

For climates ranging from –30°C (-22°F) 
to +50°C (+122°F), the following oil 
viscosities may be used:

0W–30

5W–30 (preferred)

0W–40

5W–40

Note: For maximum fuel economy, 5w-30 
oil is recommended.

It is recommended that the oil level is 
topped up using oil of the same viscosity. 
If you are unsure which oil viscosity is 
used in your vehicle, contact your Jaguar 
Dealer for advice.

If you are operating this vehicle in 
climates outside the above temperature 
range, contact your Jaguar Dealer for 
advice.

CHECK POWER STEERING 
FLUID LEVEL

Caution: It is imperative that the power 
steering system does not become 
contaminated in any way. Always 
dispense fluid from a fresh sealed 
container and clean the area around 
the reservoir neck, both before and 
after topping up. Never return drained 
fluid to the system.

Refer to pages 187, 188 for power 
steering fluid reservoir location.

Check the fluid level when the engine is 
COLD and the vehicle is on a flat, level 
surface.

Wipe clean and remove the filler cap from 
the reservoir; take great care to prevent 
any foreign matter from entering.

Check that the fluid level is between the 
marks on the dipstick or between the 
MAX/MIN indications on the outside of 
the transparent reservoir.

If necessary, top up with DEXRON III 
power steering fluid, DO NOT OVERFILL.

Refit the filler cap.

Should the level be very low, report the 
loss of fluid to the nearest Jaguar Dealer.

CHECK BRAKE FLUID 
RESERVOIR

Refer to pages 187, 188 for brake fluid 
reservoir location.

Caution: 
• While handling brake fluid, take 

extreme care; brake fluid must not 
contact the vehicle paintwork.

• Always use fresh, clean fluid from a 

new container. Never introduce 
used brake fluid into the system.

The fluid is visible through the translucent 
casing of the reservoir and must be 
maintained at the MAX mark.

!

WARNING:

The fluid level will drop as the brake 
pads wear. If the level is very low, 
report the loss of fluid to the nearest 
Jaguar Dealer. Do not drive the vehicle 
until the cause is rectified.

If necessary, top up as follows:

Before removing the cap, clean the 
reservoir and cap thoroughly with a lint 
free cloth to ensure that no foreign matter 
enters the reservoir.
