Engine Oil Consumption

A certain amount of oil consumption is
normal. The rate of consumption will
depend on the following:
• The quality and viscosity of the oil.
• The amount of oxidation and dilution

of the oil.

• Climatic conditions.
• The speed at which the engine is

being operated.

• Road conditions.

Drivers should expect above normal
consumption when the engine is new, and
after running-in if high speeds are
sustained.

Used Engine Oil

!

WARNING:

Prolonged and repeated contact may
cause serious skin disorders, including
dermatitis and cancer.

Always use a hand cream to protect the
skin from oil contamination. Avoid contact
with the skin as far as possible and wash
thoroughly after any contact. Keep oils
out of reach of children.

POWER STEERING FLUID

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 page for the power steering
fluid reservoir location.

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

The fluid is visible through the translucent
casing of the reservoir. Check that the
fluid level is between the MIN and MAX
marks on the side of the reservoir.

If necessary, top up with power steering
fluid as specified by your Jaguar Dealer.
Wipe clean and remove the filler cap from
the reservoir; take great care to prevent
any foreign matter from entering.

DO NOT OVERFILL.

Refit the filler cap.

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

!

WARNING:

Do not allow power steering fluid to
make contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.

!

WARNING:

Power steering fluid is toxic and
flammable. Be sure to observe all
warnings indicated on the power
steering fluid container.

!

WARNING:

Power steering fluid is highly toxic.
Keep containers sealed and out of
reach of children. If accidental
consumption of fluid is suspected,
seek medical attention immediately.

!

WARNING:

If the fluid comes into contact with the
skin or eyes, rinse immediately with
plenty of water.

Caution: The engine must not be
started if the fluid level has dropped
below the MIN mark. Severe damage to
the steering pump could result.

Caution: Seek qualified assistance
immediately if there is a noticeable
drop in the fluid level. Severe damage
to the steering pump could result.

Caution: Power steering fluid will
damage painted surfaces. Soak up any
spillage with an absorbent cloth
immediately and wash the area with a
mixture of car shampoo and water.

Caution: Do not fill the reservoir above
the MAX mark.

BRAKE FLUID RESERVOIR

!

WARNING:

Brake fluid is highly toxic - keep
containers sealed and out of the reach
of children. If accidental consumption
of fluid is suspected, seek medical
attention immediately.

!

WARNING:

If the fluid comes into contact with the
skin or eyes, rinse immediately with
plenty of water.

!

WARNING:

Take care not to spill the fluid onto a
hot engine - a fire may result.

!

WARNING:

Do not drive the vehicle with the fluid
level below the MIN mark.

Refer to pages 234 for the brake fluid
reservoir location. The reservoir is
concealed by a lift-out cover.

To remove the lift-out cover, pull the two
clips on the rear edge of the cover
towards the front of the car, and lift the
cover out.

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
non-fluffy cloth to ensure that no foreign
matter enters the reservoir.

Unscrew the filler cap and top up to the
MAX level. Use brake fluid to
specification Shell DOT4 ESL or a low
viscosity DOT4 brake fluid that meets ISO
4925 class 6 requirements.

Refit the filler cap securely.

To avoid contamination should any brake
fluid be spilt, replace the cap on the
reservoir before cleaning the spilt fluid
from the vehicle.

Caution: Seek qualified assistance
immediately if brake pedal travel is
unusually long or if there is any
significant loss of brake fluid. Driving
under such conditions could result in
extended stopping distances or
complete brake failure.

Note: The brake pedal free travel =
16.06mm (0.63 inch).

Caution: Brake fluid will damage
painted surfaces. Soak up any spillage
with an absorbent cloth immediately
and wash the area with a mixture of car
shampoo and water.

Caution: Only use new fluid from an
airtight container (fluid from opened
containers or fluid previously bled from
the system will have absorbed
moisture, which will adversely affect
performance, and must not be used).

Hydraulic fluid

!

WARNING:

• Contamination of the brake system

fluid by as little as 1 per cent will
cause rapid deterioration of the
system seals. Ensure that the brake
fluid reservoir cap is securely fitted.

• Do not allow brake fluid to make

contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.

• Brake fluid is toxic and flammable.

Be sure to observe all warnings
indicated on the brake fluid
container.

The brake hydraulic fluid in the master
cylinder and brake operating system uses
non-mineral polyglycol based brake fluid
with a minimum standard of JAGUAR
SUPER DOT 4. ONLY FLUID OF THIS
TYPE AND STANDARD MAY BE USED.
