Jaguar accessory range.

INTERIOR CARE

!

WARNING:

Do not use chemical solvents or strong
detergents when cleaning the steering
wheel or instrument panel to avoid
contamination of the air bag system.
Do not use chemical solvents or strong
detergents when cleaning the seat
-mounted side air bags. Such products
could contaminate the side air bag
system and affect performance of the
side air bag in a collision.

Brush and clean the interior regularly. Use
a vacuum cleaner where possible to
remove all dust from the interior and trim.

Carpets

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.
See your Jaguar Dealer for advice.

Headlining

Remove dust in the headlining with a
vacuum cleaner. To remove stains, dab
gently without pressing, using a fluff-free
white cloth, moistened with Jaguar
Upholstery Cleaner.

Do not use methylated spirit or solvents
as this may cause damage or
discoloration to the headlining.

EXTERIOR CARE

Note: All the cleaning materials
mentioned in this section are available
from the Jaguar Accessory Range.

Vehicle washing

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
plenty of warm (never hot) water. Rinse off
with clean water and dry using a clean,
damp chamois leather.

Do not use household soaps or
detergents. The use of Jaguar Vehicle
Shampoo is recommended.

Do not direct hoses at full force around
door and luggage compartment seals.
Using high pressure water jets on the
paintwork is not recommended.

Do not allow bird droppings or tree sap to
harden. Remove from paintwork
immediately with a lukewarm soap and
water solution.

In winter, when salt is used on the roads,
wash the vehicle frequently, and
immediately after encountering such
conditions. Clean undersides and wheel
arches using a high pressure jet.

Automatic car wash

Note: Regular use of automatic car
washes tends to dull the lustre of the
paintwork.

Vehicle Care

After leaving the car wash, switch on the
windshield wipers immediately to remove
water and prevent a build up of wax.
Jaguar Screen Clean Paste can be used
to clean any residual wax from the glass.

Caution: Ensure the rain sensitive
windshield wipers are switched OFF
before entering an automatic car wash,
to prevent damage to the wiper
blades/arms.

Removing grease or tar

Remove grease or tar with Jaguar Tar
Remover or methylated spirit (alcohol).
White spirit is also effective, but must not
be applied to rubber, particularly the
windshield wiper blades.

Glass surfaces

To avoid scratching glass surfaces, do
not clean dirty glass with dry paper or
cloth. Use clean, warm water and a
chamois leather which is reserved for
glass only.

The following products will ensure glass
surfaces and windshield wipers are kept
in good condition:

Jaguar Screen Clean Paste – Apply to the
exterior of the windshield only to ensure
effective operation of the windshield
wipers.

Jaguar Glass Cleaner – Interior and
exterior of all other glass surfaces.

Jaguar Screen Wash – Washer reservoir
additive.

Jaguar Winter Care Kit comprising
de-icer, ice scraper, anti-mist wipe cloth
and aerial cleaner – for use in adverse
weather conditions.

Note:

•

Renew the wiper blades when worn to
prevent scratching. Clean the rubber
wiper blades regularly with a mild
detergent solution.

•

It is advisable to clean the windshield
with Jaguar Screen Clean Paste at
regular intervals.

Cleaning the rear screen

To avoid damaging the heating and radio
elements when cleaning the inside of the
rear screen use only a soft, damp cloth or
chamois leather. Do not use solvents or
sharp objects to clean the glass.

Polishing paintwork and brightwork

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.

Note: The vehicle’s brightwork should be
cleaned in the same way as the paintwork:
Chrome polish or other abrasive cleaners
must not be used.

Paint chips

Scratches and chips should be touched in
before weathering action begins. Inspect
the paintwork immediately after the
vehicle has been washed.

Underhood cleaning

Underhood cleaning using high pressure
hoses or steam cleaners should be done
by a Jaguar Dealer.

Indiscriminate use of cleaning equipment
could damage or contaminate the
electronic control modules and fuse
boxes.

CARE OF ALLOY ROAD
WHEELS

The alloy road wheels are covered with a
protective anti-corrosion coating. To
prevent corrosion it is essential that this
coating is not damaged.

When removing or fitting tires always
advise the tire fitter to treat the alloy
wheels with great care and to only use
equipment with spigot or stud hole
clamping. The equipment must not have
any moving parts which contact the
wheel, and tire levers must not be used.

Wash the wheels with soap and water at
two week intervals to avoid an
accumulation of particles which could
become embedded in the wheel surface.
In salty conditions the wheels should be
cleaned weekly.

In compliance with German Road Traffic
Law, the size of the wheel rims is stamped
or cast on all wheels.
