ENGINE COOLANT CHECK
Checking the coolant level
The coolant level in the expansion tank should
be checked at least weekly (more frequently in
high mileage or severe operating conditions).
Always check the level when the system is
cold.
Ensure the coolant level is maintained between
the level indicator mark s located on the inside
of the expansion tank filler neck.
If the level has fallen appreciably, suspect
leakage or overheatin g and arrange for the
vehicle to be examined by a qualified
technician.
Diesel and V6 petrol engines V8 petrol engines
If the message
LOW COOLANT LEVEL is
displayed in the message centre, stop the
vehicle as soon as safe ty permits and top-up
the coolant reservoir with the recommended
antifreeze/water mix.
If the message centre displays the message
ENGINE OVERHEATING, pull off the
carriageway and allow the engine to idle for five
minutes and then switch off the ignition for ten
minutes. Switch on the engine and, provided
that the warning does not occur, continue your
journey, avoiding hars h acceleration. Seek
qualified assistance as soon as possible.
CAUTIONS
Running the engine without coolant will
cause serious engine damage.
If persistent coolant loss is noticed,
seek qualified assistance immediately.

BRAKE FLUID CHECK
If the quantity of fluid in the brake
reservoir drops below the
recommended level, a red warning
indicator in the instrume nt pack will illuminate
and the message BRAKE FLUID LOW will be
displayed in the message centre.
Note: If the warning indicator illuminates or the
message is displayed, while the vehicle is being
driven, stop the vehicle as soon as safety
permits by gently applying the brakes. Check
and top-up the fluid level if necessary.
Checking the fluid level
With the vehicle on level ground, check the
fluid level at least every week (more frequently
in high mileage or arduous operating
conditions).
The brake fluid reservoi r is located beneath a
cover on the raised platform to the rear of the
main underbonnet area. See ENGINE
COMPARTMENT OVERVIEW (page 196).
1. Release the catch.
2. Lift the cover forwards, then pull
rearwards, to release the hinges.
3. Clean the filler cap with a clean, dry cloth
before removing, to prevent dirt or
moisture from entering the reservoir.
WARNING
Seek qualified assistance immediately
if brake pedal travel is unusually long,
unusually short or if there is any
significant loss of br ake fluid. Driving under
such conditions could result in extended
stopping distances or co mplete brake failure.
WARNINGS
Brake fluid is highly toxic - keep
containers sealed a nd out of reach of
children. If accidental consumption is
suspected, seek medical attention
immediately.
If the fluid comes into contact with
the skin or eyes, rinse immediately
with plenty of water.
Brake fluid is highl y inflammable. Do
not allow brake fluid to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine) - a fire
may result.
Do not drive the vehicle with the fluid
level below the MIN mark.

Wheels and tyres

Tyre pressure compensation chart - high
ambient temperatures
Tyre pressures during long term vehicle
storage
To minimise the possibility and effects of flat
spots during storage, the tyres may be inflated
to the maximum pressure indicated on the tyre
wall.
Note: Before using the st ored vehicle on the
road again, ensure that correct tyre pressures
are restored.
Flat spots
If the vehicle is stati onary for a long period,
when the ambient temperature is high, the
tyres may form flat spots. When the vehicle is
driven, these flat spots will cause a vibration
which will steadily disappear as the tyres warm
up and regain their original shape. In order to minimise flat spotting, the tyre
pressures can be increa
sed. Tyre pressures
should be increased by 0.14 bar/14 kPa (2
lbf/in²) for each 10°C (20°F) temperature
increase above 20°C (68°F)
Long term storage
Flat spotting can be minimised during long
term storage, by increasing the tyre pressures
to the maximum indicated on the tyre sidewall.
Note: The tyre pressures s hould be reduced to
the correct pressure before the vehicle is
driven.
Tyre wear
Good driving practise will improve the mileage
you obtain from your tyres, and avoid
unnecessary damage.
• Always ensure that the tyre pressures are
correctly adjusted.
• Always observe the posted speed limits,
and advisory speeds for bends.
• Avoid pulling away quickly, or hard
acceleration.
• Avoid making fast turns or braking
sharply.
• Wherever possible, avoid potholes, or
obstacles on the road.
• Do not drive up kerbs, or rub the tyres
against them when parking.
