Driving dynamics

TracDSC
TracDSC is an alternative setting of DSC with
reduced system interventions. With TracDSC
engaged, traction may be somewhat increased,
although stability may be reduced compared to
normal DSC. TracDSC is intended for use only
on dry tarmac, by suitably experienced drivers
and should not be select ed for other surfaces
or by drivers with insufficient skill and training
to operate the vehicle safely with the TracDSC
function engaged.
The less restrictive TracDSC setting may be
preferred, for example, by expert drivers
engaged in high performance driving on dry
Tarmac surfaces such as tracks and circuits.
Switching between DSC and Trac DSC
• Press and hold the DSC switch for less
than 10 seconds.
• The message centre will temporarily
display either Trac DSC or DSC ON.
• The warning indicator in the instrument
panel will illuminate while Trac DSC is
selected.
• The warning indicator will flash when DSC
or Trac DSC is active.
Note: If cruise control is engaged, it will
automatically disengage if stability control
activates.
Switching between DSC OFF and ON
Switching DSC OFF
• Press and hold the DSC switch for more
than 10 seconds.
• The message centre will display DSC OFF
and a short warning chime will sound.
• The warning indicator in the instrument
panel will illuminate.
Switching DSC ON
If DSC is OFF:
• Press and release the DSC switch.
• The DSC system will switch on, the
message centre will temporarily display
DSC ON .
• The warning indicator in the instrument
panel will be extinguished.
Note: Switching the engine off and then on
again, will always revert DSC status to DSC ON,
regardless of which Ja guarDrive Control mode
is selected.
WARNING
Vehicle safety may be reduced by
inappropriate use of TracDSC.
TracDSC should only be used in
suitable conditions.

Fuel and refuelling

Sulphur content
In some countries diesel may contain higher
levers of Sulphur, wh ich could cause damage
to the vehicle, if in doubt contact a local
Dealer/Authorised Repairer for advice.
RUNNING OUT OF FUEL
Note: If the vehicle does run out of fuel, a
minimum of 4 litres (0.9 gallons) will be
required to restart the engine. The vehicle will
need to be driven 1.6-5 km (1-3 miles) in order
to reset the engine management and
monitoring systems.
Note: If the vehicle does run out of fuel,
seeking qualified assistance is advisable.
Diesel engines
Vehicles with diesel e ngines are equipped with
a system to prevent the fuel tank from
emptying completely. When the fuel reaches a
minimum level, the system will activate a
reduced power mode (i.e . the engine will not
run properly). This will be followed by the
engine stopping in a pproximately 1.6 km
(1 mile). This feature prevents the fuel system from
running dry, which could cause damage to the
vehicle. If the gauge indicates low fuel or the
warning indicator illumi
nates, the fuel tank
should be refuelled as soon as possible at the
next filling stat ion, with at least 4 litres (0.9
gallons) of fuel.
If the system protection function has activated,
the vehicle must firstly be refuelled, then
restarted using the following procedure:
1. With the brake pedal pressed, press and
hold the engine START/STOP button and
crank the engine for five seconds.
2. Release the START/STOP button.
3. With the brake pedal pressed, press and
release the START/STOP button to crank
the engine. The engine should start within
approximately five seconds.
Note: If the engine does not start, pause for ten
seconds with the ignition in convenience
mode, before re peating the procedure from the
beginning.
FUEL CUT-OFF
The fuel system cut-off forms part of the
Supplementary Restraint System (SRS) fitted
to your vehicle. Following an impact, and
depending on the severity , the fuel pump may
be switched off.
CAUTION
Your vehicle is fitted with a Diesel
Particulate Filter (DPF), the maximum
Sulphur content must not exceed 0.005%.
Using an incorrect fuel will cause serious
damage to the DPF. See DIESEL
PARTICULATE FILTER (DPF) (page 135).
CAUTION
Avoid running out of fuel. Doing so can
cause damage to th e vehicle's engine,
fuel and emission control systems.
CAUTION
Do not crank the engine for longer than
30 seconds, or damage to the fuel pump
may occur.

Resetting the fuel cut-off
1.Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thor oughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualified advice and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
FUEL FILLER FLAP
Note: The fuel filler flap cannot be opened
when the alarm system is armed.
The fuel filler flap is located on the right-hand
side of the vehicle, at the rear.
1. Ensure that the vehicle is fully unlocked.
Push and release the rear of the flap (in the
area indicated in the illustration) to
unlatch.
2. Pull the fuel filler flap open. The label on
the inside of the flap indicates the correct
fuel for the vehicle. 3.
Twist the cap counte r-clockwise to undo.
4. Stow the cap on the lip provided on the top
of the hinge arm, as shown.
When replacing the cap, turn it clockwise until
the ratchet clicks. Failur e to do so could cause
the Engine malfunction warning indicator to
illuminate.
To close the filler flap, pus h the flap closed until
it latches.
WARNING
The fuel cut-off should never be reset
if you can smell fuel, or a leak can be
seen. Doing so can lead to a fire
which may cause persona l injury or death.
WARNINGS
Open the fuel filler cap slowly and
allow the pressure to release before
fully removing the cap to avoid fuel
spillage due to rapid expansion.
Take note of all warnings and
instructions given on the label affixed
to the inside of the fi ller flap. Failure to
do so may result in injury or death.

Underbonnet cleaning
CAUTIONS
Commercially operated automatic car
washes, jet washes and power-operated
mops, are not recommen ded. The detergents
used can contain certain chemicals which
may, over time, be detrimental to some
exterior parts of the vehicle. Prolonged usage
of automatic car wash es and power-operated
mops will also cause fine scratches in the paint
surface.
Ensure that Auto wipe is not selected
when entering a car wash, or damage to
the wiper blades and arms can occur if they
operate during the wash cycle.
Ensure that when using an automatic
drive through car wash, N (Neutral) is
selected and that the ignition is left in
convenience mode for the duration of the
wash.
CAUTIONS
Do not use a high pr essure washer or
steam cleaner in the engine
compartment. Damage to components could
occur.
Ensure that the brake fluid reservoir is
kept dry at all times. Only use a clean,
dry cloth to clean the brake fluid cap and
reservoir.

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

11.Wear rate indicator. A tyre rated at 400 for
example, will last twice as long as a tyre
rated at 200.
12. The traction rating grades a tyres
performance when stopping on a wet road
surface. The higher the grade the better the
braking performance. The grades from
highest to lowest are, AA, A, B, and C.
13. The maximum load which can be carried
by the tyre.
14. Heat resistance grading. The tyre's
resistance to heat is grade A, B, or C, with
A indicating the greatest resistance to heat.
This grading is provided for a correctly
inflated tyre, which is being used within its
speed and loading limits.
15. The maximum inflation pressure for the
tyre. This pressure should not be used for
normal driving.

WARNINGS
Defective tyres are dangerous. Do not
drive the vehicle if a tyre is damaged,
excessively worn, or incorrectly
inflated. Doing so may lead to premature tyre
failure.
Avoid contaminating the tyres with
vehicle fluids as they may cause
damage to the tyre.
Avoid spinning the wh eels. The forces
released can damage the structure of
the tyre and cause it to fail. Doing so
may lead to premature tyre failure.
If wheel spin is unavoidable due to a
loss of traction (i n deep snow, for
example), do not exceed the 50 km/h
(30 mph) point on the speedometer. Doing so
may lead to premature tyre failure.
Do not exceed the maximum pressure
stated on the sidewall of the tyre.
Over-inflation could cause the tyre to
fail suddenly.
WARNINGS
Never drive your vehicle if the tyre
pressures are incorrect.
Under-inflation causes excessive
flexing and uneven tyre we ar. This can lead to
sudden tyre failure. Ov er-inflation causes a
harsh ride, uneven tyre wear and poor
handling.
Pressure checks should only be
carried out when the tyres are cold,
and the vehicle has been stationary
for more than three hours. A hot tyre at or
below recommended cold inflation pressure is
dangerously under-inflated.
