Driving dynamics
172

Note: In rare circumstances, when TracDSC is
selected or DSC is o ff, high acceleration on
rough roads may cause DSC to switch back on.
This prevents high loads on the vehicle
driveline. DSC will su bsequently remain on,
unless TracDSC is selected or DSC is switched
off manually.
Stability control indicator
If there is a fault, the warning
indicator will ill uminate in the
instrument panel and the message
centre will display DSC NOT AVAILABLE with
an amber backlight.
It is safe to drive the vehicle, but the DSC
system will not activa te under wheel spin or
slide conditions. You should seek qualified
assistance as soon as possible.
Adaptive dynamics
(Supercharged vehicles only)
Jaguar Adaptive dy namics continuously
monitors the road a nd driver inputs and
optimises the vehicle suspension settings for
ride comfort and control.
The adaptive dynamics system is linked to
Dynamic mode, modifying the suspension
settings for a more sporting character.
If the message centre displays the message
ADAPTIVE DYNAMICS FAULT , a fault has been
detected in the adaptive dynamics system.
Seek qualified assistan ce as soon as possible.
Active Differential Control (E-diff)
(Supercharged vehicles only)
The E-diff improves trac tion when one driven
wheel has more grip than the other. This
improves progress out of corners and on
patchy or uneven surfaces. The E-diff can also
increase stability in oversteer situations,
depending on road c onditions and driver
inputs. Settings for the E-diff are made automatically,
without the need for driver selection.
If there is a fault with the E-diff system, the
message centre will display
EDIFF SYSTEM
FAULT . If DSC is off, then TracDSC will be
selected automatically. The driver can still
switch between DSC mode s, as normal and the
vehicle is safe to dr ive, but seek qualified
assistance as soon as possible.
Note: If the E-diff is active continuously for an
extended period (e.g. on a patchy surface with
DSC off) then the E-diff may be temporarily
deactivated to prevent ov erheating. If DSC is
off, then TracDSC will be selected
automatically. The mess age centre will display
EDIFF NOT AVAILABLE . The driver can still
switch between DSC modes as normal and the
E-diff will become availa ble again automatically
when it has cool ed sufficiently.

Load carrying
182

GENERAL INFORMATION
Weights and load capacities
Note: It is the driver's re sponsibility to ensure
that the maximum weights are not exceeded,
and that the load is distributed correctly within
the vehicle.
Information and values for the maximum
weights can be found in the Weights section.
See WEIGHTS (page 259).
Roof racks
LUGGAGE ANCHOR POINTS
Four load securing rings are provided in the
rear luggage area to assi st in safely securing

Towing

TOWING A TRAILER (V6 petrol and
diesel vehicles only)
Note: It is the driver's responsibility to ensure
that the towing vehicle, and the trailer are being
used correctly, and in accordance with
manufacturers recommendations and any
applicable legislation. Your Dealer/Authorised Repairer and main
motoring and caravanni
ng organisation can
advise you on towing, towing weight capacities
and about regulations that apply in other
countries.
The following are important points of safety,
stability and comfort, upon which further
advice should be sought:
• Maximum braked towing weight is
permissible, provided that long periods of
uphill driving on gradients over 8% are not
undertaken.
• In high altitude mount ainous regions, the
thinner atmosphere can reduce engine
performance. Abov e 1000 metres (3250
feet), the stipulated maximum permitted
gross train weight mu st be reduced by
10% for every 1000 metres (3250 feet) in
altitude.
E95507
WARNINGS
Never exceed the maximum weights
for either the vehicle, or the trailer.
Doing so can cause accelerated wear
and damage to the ve hicle. It can also
adversely affect vehicle stability and braking,
which in turn can lead to loss of control and
increased braking distance resulting in a
rollover or crash.
To preserve handling and stability,
only fit Jaguar approved towing
accessories.
Never use towing eyes or lashing
points to tow a trailer. They have not
been designed for this purpose and
doing so may cause them to fail resulting in
injury or death.
When towing, do not exceed 100
km/h (60 mph) or 80 km/h (50 mph)
if a temporary spare wheel is in use.

Vehicle care

CLEANING THE ALLOY WHEELS
Wash the wheels with soap and water, this
should be done more frequently when the
wheels are exposed to heavy dirt deposits, salt,
clay etc. If you are unsure how often to clean
the wheels in particular conditions, seek advice
from your Dealer/A uthorised Repairer.
Jaguar approved wheel cleaner should be used
to remove heavy soiling.
CLEANING THE EXTERIOR
Washing the vehicle paintwork
Remove heavy deposits of mud and dirt with a
hose before washing the vehicle.
When salt is used on the roads, wash the
vehicle immediately after encountering such
conditions. Clean undersid es and wheel arches
using a high pressure jet.
Wash the vehicle frequently using a sponge
and generous quantities of cold or luke warm
water containing a suitable car shampoo. Rinse
thoroughly and dry with a chamois leather or
synthetic substitute.
For best results, do not wash the vehicle under
strong sunlight. Always allow the vehicle to
cool down before washing.
Do not use a dry cloth to wipe dirty paintwork.
Dust and gritty substances are abrasive and
will scratch the paintwork. Remove dirt using a
cellulose sponge and plen ty of warm (never
hot) water. Rinse off with clean water and dry
using a clean, damp cham ois leather. Wash the
vehicle frequently.
CAUTION
Do not use non-approved, or acid based
wheel cleaners. These can damage the
wheel coating which may lead to corrosion of
the wheel rims.
CAUTIONS
Some high pressure cleaning systems
are sufficiently powe rful to penetrate
door and window seals, and damage trim and
door locks. Never aim the water jet directly at
the engine air intake, he ater air intakes, body
seals (doors, sunroof, windows etc.) or at any
components which may be damaged (lamps,
mirrors, exterior trim etc.).
Ensure that you read and comply with all
warnings and instruct ions supplied with
any cleaning products.
Never use cleaning products which are
not approved for use on vehicles.
CAUTION
Substances which are corrosive, such
as bird droppings, tree resin, dead
insects, tar spots, road salt and industrial fall
out, can damage the vehic le's paintwork. Any
such deposits should be removed as soon as
possible to prevent damage.

To avoid damaging the heating elements when
cleaning the inside of th e rear screen, use only
a soft damp cloth/chamois leather. Do not use
solvents or sharp objects to clean the glass.
Removing grease and tar
Remove grease or tar with Jaguar Tar Remover
or methylated spirit (a lcohol). White spirit is
also effective, but mu st not be applied to
rubber, particularly the windscreen wiper
blades.
Bird droppings
Do not allow bird droppings or tree sap to
harden. Remove from paintwork immediately
with a lukewarm soap and water solution.
Polishing
For maximum protection against road dust,
salts, industrial fall-out etc., it is recommended
that the vehicle is polished regularly using
Jaguar polish and a polishing cloth.
CLEANING THE INTERIOR
CAUTION
Ensure that after using methylated or
white spirit, the area is washed
immediately with soapy water, to remove all
traces of spirit.
CAUTION
Chrome polish, or other abrasive
cleaners, must not be used on the
vehicle's brightwork. The vehicle's brightwork
should be cleaned using a sponge and
generous quantities of cold or lukewarm water
only. Rinse thoroughly a nd dry with a chamois
leather or synthetic substitute.
WARNING

POWER STEERING FLUID CHECK
Checking the fluid level
Check and top-up the fluid with the vehicle on
level ground, with the e ngine switched off and
the system cold. Ensure that the steering wheel
is not turned after stopping the engine.
The level of fluid can be seen through the
translucent body of the reservoir. The fluid level shoul
d be between the MIN and
the MAX marks.
Topping up the fluid
1.Clean the filler cap before removing to
prevent dirt from entering the reservoir.
2. Remove filler cap.
3. Using Mobil ATF320, top-up the reservoir
until the fluid level is between the MIN and
MAX marks.
4. Replace filler cap.
WARNINGS
Power steering fluid is highly toxic.
Keep containers sealed and out of
reach of children. If accidental
consumption of fluid is suspected, seek
medical attenti on immediately.
If the fluid comes into contact with
the skin or eyes, rinse immediately
with plenty of water.
Power steering fluid is highly
inflammable. Do not allow power
steering fluid to come into contact
with naked flames or other sources of ignition
(e.g. a hot engine) - a fire may result.
CAUTIONS
The engine must not be started if the
fluid level has dropped below the MIN
mark. Severe damage to the steering pump
could result.
Seek qualified assistance immediately if
there is a noticeable drop in the fluid
level. Severe damage to the steering pump
could result.
If fluid loss is slow, the reservoir may be
topped-up to the upper level mark to
enable the vehicle to be driven to a repair
facility for examination. However, it is
recommended that you seek qualified
assistance before driving the vehicle.CAUTIONS
It is imperative that the power steering
system does not beco me contaminated
in any way. Always use new fluid and clean the
area around the filler neck both before
removing the filler ca p and after topping up.
Never return drained fluid to the system.
Power steering fluid will damage
painted surfaces. So ak up any spillage
with an absorbent cloth immediately and wash
the area with a mixture of car shampoo and
water.
Do not fill the reservoir above the MAX
mark.

GENERAL INFORMATION
Tyre markings
1.P indicates that the tyre is for passenger
vehicle use.
2. The width of the tyre fr om sidewall edge to
sidewall edge in millimetres.
3. The aspect ratio, also known as the profile,
gives the sidewall height as a percentage
of the tread width. So, if the tread width is
205 mm, and the aspect ratio is 50, the
sidewall height will be 102 mm.
4. R indicates that the ty re is of Radial ply
construction.
5. The diameter of the wheel rim given in
inches.
6. The load index for the tyre. This index is
not always shown.
7. The speed rating denotes the maximum
speed at which the tyre should be used for
extended periods. † 8.
Tyre manufacturing standard information,
which can be used for tyre recalls and
other checking processe s. Most of this
information relates to the manufacturer,
place of manufacture etc. The last four
numbers are the date of manufacture. For
example, if the number was 3106, the tyre
was made in the 31st week of 2006.
9. M+S or M/S indicates that the tyre has
been designed with some capability for
mud and snow.
10. The number of plies in both the tread area,
and the sidewall area, indicates how many
layers of rubber coat ed material make up
the structure of the tyre. Information is
also provided on the type of materials

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

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.

Wheels and tyres
218

All of the vehicle's tyres (including the spare)
should be checked regularly for damage, wear
and distortion. If you are in any doubt about the
condition of a tyre, have it checked immediately
by a tyre repair centre or your
Dealer/Authorised repairer.
Checking the tyre pressures
The recommended tyre pressures are listed on
a placard label fixed to the end of the left-hand
side door. These pressures provide optimum
ride and handling charac teristics for all normal
operating conditions.
If winter tyres are fitted, please refer to the
winter tyre pressure information. SeeUSING
WINTER TYRES (page 223).
In the interest of safe ty, reliability and fuel
efficiency, check the tyres, including the spare,
for condition and pressu re on a weekly basis
and before long journeys.
Do not check tyre pressures immediately after
the vehicle has travelled in excess of 1.6 km
(1.0 mile). Tyre temperatures and pressures
increase when running. Deflating a warm tyre
to the recommended pressure will result in
under-inflation.
If tyre pressures are checked while the vehicle
is inside a protected covered area, e.g. a
garage, and subsequent ly driven in lower
outdoor temperatures, tyre under-inflation
could occur.
A slight pressure loss occurs naturally with
time. If this exceeds 0.14 bar (2 lbf/in², 14 kPa,)
per week, have the cause investigated and
rectified by qualified assistance.
Tyre pressures (including the spare) should be
checked at least once a week with normal
on-road use, but should be checked daily if the
vehicle is used off-road. Always check the tyre
pressures before setti ng off on a long journey.
If it is necessary to check tyre pressures when
the tyres are warm, you should expect the
pressures to have increased by up to
0.3-0.4 bar (4-6 lbf/in², 30-40 kpa). Do not
reduce the tyre pressures to the cold inflation
pressure under these circumstances. Allow the
tyres to cool fully before adjusting the
pressures.
If the vehicle has been parked in
strong sunlight, or used in high
ambient temperatures do not reduce
the tyre pressures. move the vehicle into the
shade and allow the tyres to cool before
re-checking the pressures.
WARNING
Tyre pressures should be checked
regularly using an accurate pressure
gauge, when the tyres are cold.
Failure to properly maintain your tyre
pressures could increase the risk of tyre failure
resulting in loss of vehicle control and
personal injury.
