Towing

RECOMMENDED TOWING WEIGHTS
Nose/tongue weight must be the greater of
50 kg (110 lbs) or 7% of the actual trailer
weight, up to the maximum tow hitch load.
Nose/tongue weight can be measured using a
proprietary brand of nose weight indicator.
If it is necessary to increase the nose/tongue
weight up to the maximu m allowed, the vehicle
load should be reduced accordingly. This
ensures that the Gross Vehicle Weight (GVW),
and maximum rear axle load, are not exceeded.
Note: When towing the maximum permissible
gross vehicle weight can be increased by a
maximum of 100 kg (220 lb.) provided that the
road speed is limited to 100 km/h (60 mph).
Note: When calculating rear axle loading,
remember that the trailer nose/tongue weight,
the load in the vehicle's luggage area and the
weight of rear seat pa ssengers must all be
added together.
Towing weights - Australia only
The weight of a traile r must not exceed 1.5
times the towing vehicle’s weight. The
nose/tongue weight must be a minimum of 7%
of gross caravan/trai ler weight, up to a
maximum of 350 kg (722 lbs).
ESSENTIAL TOWING CHECKS
• The trailer should be parallel to the ground
when loaded and connected to the vehicle.
• When calculating the laden weight of the
trailer remember to include the weight of
the trailer, plus the weight of the load.
• If the load can be divided between the
vehicle and trailer, loading more weight
into the vehicle will generally improve
stability. Do not exceed the vehicle's
weight limits. See WEIGHTS (page 259).
• Ensure that all applic able regulations and
legislation are complied with when loading
and towing a trailer.
• Increase rear tyre pressures of the towing
vehicle to those for maximum vehicle
loading conditions.
• Ensure trailer tyre pressures are set to
trailer manufacturer' s recommendations.
• If the vehicle is loaded to maximum Gross
Vehicle Weight (GVW) the nose weight is
limited (see Towi ng weights table).
• Ensure that a suitable breakaway cable or
secondary coupling is used. Refer to the
trailer manufacturer' s instructions for
guidance.
• Ensure that the tow ball is secure.
• Check the operation of all trailer lights.
Maximum permissible
towing weights
Unbraked trailers 750 kg (1653 lb.) Trailers with
overrun brakes 1850 kg (4080 lb.)
Nose/Tongue weight 75 kg (165 lb.)
WARNING
Do not exceed the Gross Vehicle
Weight (GVW), m aximum rear axle
weight, maximum trailer weight, or
nose/tongue weight. Exceeding any of these
limits could cause inst ability and loss of
control. See WEIGHTS (page 259).
WARNING
Do not loop the breakaway cable over
the tow ball as it may slide off.

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.

Vehicle care

Carpet and mats
Marks or stains can be removed by gentle
scrubbing with a weak solution of soap and
warm water.
For more stubborn stains a commercially
available carpet cleaner should be used.
Seat belts
Extend the seat belts fully, then use warm
water and a non-detergent soap to clean. Allow
the seat belts to dry naturally whilst fully
extended and do not allow the belts to retract
until fully dry.
Note: Whilst cleaning the seat belt, take the
opportunity to examine the webbing for
damage and wear. Any wear or damage should
be reported to, and rectified by, a Dealer/
Authorised Repairer.
Airbag module covers
REPAIRING MINOR PAINT DAMAGE
Regularly inspect the paintwork for damage.
Any stone chips, fractures, or deep scratches,
in the paint/bodywork should be repaired
promptly. Bare metal wi ll corrode quickly, and
if left untreated can resu lt in expensive repairs.
Minor chips and scratches can be touched up
using materials and advi ce available from a
Dealer/Authorised Repairer. Larger areas of
damage will require pr ofessional repair, and
you should consult a Dealer/Authorised
Repairer.
WARNING
Do not allow any water, cleaning
products, or fabric from cloths to
enter the seat belt mechanism. Any
substance which enters the mechanism may
affect the performance of the seat belt in an
impact.
WARNINGS
Airbag covers shoul d only be cleaned
using a slightly dampened cloth, and
a small amount of upholstery cleaner.
Do not allow the airbag covers, or
surrounding areas, to become
contaminated with liquids. Any
substance which enters the mechanism, can
prevent correct deploy ment of an airbag
during an impact.

Safety in the garageFuel system
Poisonous fluids
Fluids used in motor vehicles are poisonous
and should not be consumed or brought into
contact with open wounds. These include;
battery acid, antifreeze, brake, clutch and
power steering fluid, petrol, diesel, engine oil
and windscreen washer additives.
For your own safety, always read and obey all
instructions printed on labels and containers.
Used engine oil
Prolonged contact with engine oil may cause
serious skin disorders, including dermatitis
and cancer of the skin. Always wash
thoroughly after contact.
It is illegal to pollute drains, water
courses or soil. Use authorised
waste disposal site s to dispose of
used oil and toxic chemicals.
WARNINGS
If the vehicle has been driven
recently, do not touch exhaust and
cooling system components until the
engine has cooled.
Never leave the engi ne running in an
unventilated area - exhaust gases are
poisonous and extremely dangerous.
Do not work beneath the vehicle with
the wheel changing jack as the only
means of support.
Keep your hands and clothing away
from drive belts, pulleys and fans.
Some fans may continue to operate
after the engi ne has stopped.
Remove metal wrist bands and
jewellery, before working in the
engine compartment.
Do not touch electrical leads or
components while the engine is
running, or with the starter switch
turned on.
Do not allow tools or metal parts of
the vehicle to make contact with the
battery leads or terminals.WARNINGS
Under no circumstances should any
part of the fuel system be dismantled
or replaced by anyone other than a
suitably qualified vehicle technician. Failure to
comply with this instruct ion, may result in fuel
spillage with a consequent serious risk of fire.
Ensure sparks and naked lights are
kept away from the engine
compartment.
Wear protective cl othing, including,
where practicable, gloves made from
an impervious material.

213
Vehicle battery

Your vehicle is fitted with a low maintenance
battery, which is located under the floor of the
luggage compartment.
In hot climates more frequent checks of the
battery electrolyte level and condition are
required. If necessary, the battery cells can be
topped up using di stilled water.
When the ignition is switched on, but without
the engine running, BATTERY NOT CHARGING
is displayed in the mess age centre. The battery
will only charge when the engine is running.
Note: Do not connect any 12 volt equipment
(e.g. a 12 volt inspection lamp), directly to the
battery terminals. Use the accessory socket
located in the cubby box, for connecting Jaguar
approved accessories.
Battery Monitoring System (BMS)
Your vehicle is equipped with a Battery
Monitoring System (BMS) which manages the
battery charging system and, if excessive
battery discharge is o ccurring when the engine
isn't running, shuts down non-essential
electrical systems to protect battery power.
In the event that too many electrical systems
are operational when the engine is not running,
and the battery charge is insufficient, the audio
and entertainment systems (if active) and
climate control system will be switched off.
This will be confirmed by a low battery warning
message displayed on the touch-screen. If this
occurs, switch on and run the engine for at
least five minutes, preferably with all auxiliary
electrical systems switched off (e.g. lights,
wipers, climate control, seat heaters etc.).
Note: The audio system can be operated
during this five minute period when the engine
is running.
If the engine is switched off before the five
minute period ends and the audio system is
switched on, the warning message will
re-appear on the touch-sc reen and the audio,
entertainment and climate control systems will
switch off again. For this reason, it is important
that the engine is left running for the full five
minute period.
Charging faults
If there is a fault in the battery charging system,
CHARGING FAULT is displayed with red
backlighting in the mess age centre. If this
occurs, switch off all non-essential electrical
systems and seek qualified assistance at the
earliest opportunity.
CAUTION
Do not allow battery electrolyte to come
into contact with fabrics or painted
surfaces. If battery electrolyte comes into
contact with any surfac e, the surface should
be washed down immedi ately with copious
amounts of clean water. Battery electrolyte is
both corrosive and toxic, and can damage a
wide range of materials if left.

USING BOOSTER CABLES
Note: Before connecti ng booster cables,
ensure that the battery connections on the
disabled vehicle are correct and that all
electrical equipment has been switched off.
1. Connect one end of the positive booster
cable to the positive terminal on the donor
vehicle's battery.
2. Connect the other end of the positive
booster cable to the positive terminal on
the disabled vehicle's battery. 3.
Connect one end of th e negative booster
cable to the earth point of the donor vehicle
that is recommended for jump starting by
the manufacturer.
4. Connect the other end of the negative
booster cable to a suitable earth point on
the disabled vehicle. The earth point
should be at least 0.5 metres (20 inches)
away from the battery and as far as
possible from any fu el or brake pipes.
• Check that all cables are clear of any
moving components and that all four
connections are secure.
5. Start the engine of the donor vehicle, and
allow it to idle for a few minutes.
6. Start the engine of the disabled vehicle.
7. Allow both vehicles to idle for two minutes.
8. Switch off the donor vehicle.
Disconnecting the cables
Note: Do not switch on any electrical
equipment until after th e cables have been
disconnected.
The engine should be running on the
previously disabled ve hicle and the engine
switched off on the donor vehicle. Disconnect
the booster cables in the exact reverse order of
that used for connection.
WARNINGS
Always wear appropriate eye
protection when working with
batteries.
During normal use, batteries emit
explosive hydrogen gas - ensure
sparks and naked lights are kept away
from the luggage compartment.
Do not attempt to start the vehicle if
the electrolyte in the battery is
suspected of being frozen.
Make sure both batt eries are of the 12
volt type and that the booster cables
have insulated clamps and are
approved for use with 12 volt batteries.
Do not disconnect the discharged
battery.
Do not connect posit ive (+) terminals
to negative (-) terminals and ensure
booster cables are kept away from
any moving parts in the engine compartment.
Do not connect a booster cable to the
negative (-) terminal of the battery.
Always connect to the recommended
earthing point.
WARNING
To avoid serious in jury use extreme
caution when removing the booster
cables as the engine will be running
on the previously disabl ed vehicle. This means
that you may be workin g close to components
which are moving at high speed, carry high
voltage, or may be hot.

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.
WARNINGS

221
Wheels and tyres

Wear indicators
When the tread has worn down to
approximately 2 mm, wear indicators start to
appear at the surface of the tread pattern. This
produces a continuous band of rubber across
the tread as a visual indicator.
To maintain performance and grip the tyre
must be replaced as soon as the wear indicator
becomes visible. Sooner, if legislation requires
replacement at a greater tread depth.
Note: Tread depth should be checked
regularly, in some case more frequently than
the service intervals. For advice on checking
tyres contact your Dealer/Authorised repairer
or a tyre dealer.
Age degradation
Tyres degrade over time due to the effects of
ultraviolet light, extreme temperatures, high
loads, and environmen tal conditions. It is
recommended that tyres are replaced at least
every six years, but they may require
replacement more frequently.
Jaguar recommends that even if unused, the
spare tyre be replaced at the same time as the
four road tyres.
Punctured tyres
Tyre checks
Not all punctures result in the tyre deflating
immediately. Therefore, it is important to check
the tyres for damage and foreign objects,
regularly.
When driving, if a sudden vibration, or change
to the vehicle's hand ling is noticed, reduce
speed immediately. Do not brake hard, or make
any sudden manoeuvres or direction changes.
Drive slowly to an area off the main highway
and stop the vehicle.
Note: Driving the vehicle to a safe area may
cause damage to th e punctured tyre, but
occupant safety is far more important.
Inspect the tyres for signs of punctures,
damage or under inflati on. If any damage or
deformity is detected, the tyre should be
replaced. If a spare tyre is not available, then
the vehicle should be reco vered to a tyre repair
centre, or Dealer/Approved repairer.
WARNING
Wear indicators show the minimum
tread depth recommended by the
manufacturers. Tyres which have
worn to this point will have reduced grip and
poor water displacement characteristics.
CAUTION
If tread wear is uneve n across a tyre, or
the tyre wears excessively, the vehicle
should be checked by your Dealer/Authorised
Repairer as soon as possible.
E91698
WARNING
Do not drive the vehicle with a
punctured tyre. Even if the punctured
tyre has not deflated, it is unsafe to
use, as the tyre may deflate suddenly at any
time. See TYRE REPAIR KIT (page 229).
