Regular Checks
In the interests of safety and reliability,
it is advisable to carry out the following
checks at the recommended intervals,
and always before starting on a long
journey.
Daily
Check that there is sufficient fuel for the
journey intended, particularly at night
and before joining motorways.
Weekly
Tyres– Check the tyres, including the
spare, for condition and pressure.
Tyre pressures are explained on page 8 - 8
and shown on a label inside the fuel filler
flap.
Lights – Check that all exterior lights and
direction indicators function correctly
and that the lenses are clean.
Engine oil – With the vehicle standing
on level ground, check the oil level and
top up if necessary with oil of the correct
grade.
Engine coolant – With the engine cold,
check the level of the coolant in the
coolant reservoir header tank. Any loss of
fluid must be checked by a Jaguar
Retailer. Brake fluid
– Check the level of the fluid
in the brake fluid reservoir. Top up if
necessary with new, unused Jaguar
approved brake fluid.
The reservoir is initially nearly full,
but the level will drop as the brake pads
wear. If the level appears unusually low,
location of the fluid leakage must be
checked by a Jaguar Retailer.
Power steering fluid – With the engine
cold, check the level of the fluid in the
power steering fluid reservoir. Top up if
necessary with fluid of the correct
specification. Any loss of fluid should be
checked by a Jaguar Retailer.
Windscreen washer fluid – Top up
with windscreen washer fluid and clean
soft water. Check the operation of the
washers. It is recommended that you
use Jaguar Windscreen Washer Fluid to
keep the glass clean and also to prevent
the fluid from freezing during cold
weather.
Monthly
Wiper blades – Check the quality of the
wipe. If smearing or juddering is evident,
clean the windscreen and wiper blades.
Used Engine Oil
!WARNING:
Prolonged and repeated contact may
cause serious skin disorders,
including dermatitis and cancer.
Always use a hand cream to protect the
skin from oil contamination.
Avoid contact with the skin as far as
possible and wash thoroughly after any
contact. Keep oils out of reach of
children.
PROTECT THE ENVIRONMENT: It is
illegal to pollute drai ns, watercourses and
soil. Use authorised waste collection
facilities, including civic amenity sites and
garages providing fa cilities for the
disposal of used oi l, oil filters and
batteries. If in doubt, contact your Local
Authority for advice on disposal.

Check Windscreen/Headlight
Washer Reservoir
Refer to page 7 - 5 for windscreen washer
reservoir location.
The washer reservoir contains the fluid
for the windscreen washers and the
headlight powerwash system (where
fitted).
Fill to just below th e neck with Jaguar
Windscreen Washer Fl uid diluted with
clean, preferably soft water as specified in
the instructions on the bottle.
Do not overfill.
Note: Using a non-approved fluid may
adversely affect the wiper blade rubber,
resulting in ineffectual and noisy wiping. Cold weather precautions
To prevent damage to the pump during
freezing conditions, use Jaguar
Windscreen Washer Fluid at the strength
shown on the bottle, for the anticipated
ambient temperature.
!WARNING:
1. Windscreen washer fluid is toxic and in concentrated form is
flammable. Be sure to observe all
warnings indicated on the washer
solution container.
Under no circumstances must
cooling system anti-freeze be
used, since this will damage the
paintwork.
2. State or local regulations on volatile organic compounds may
restrict the use of methanol,
a common windscreen washer
anti-freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used only
if they provide cold weather
protection without damaging the
vehicle’s paint finish, wiper blades
or washer system.

Battery lead disconnection
Caution:
1. Under no circumstances should a battery be discon nected whilst
the ignition circuit is live,
as permanent damage to the
instrument cluster may occur.
2. Disconnect the negative lead (earth terminal) first.
Fold the luggage compartment floor panel
forwards (see page 6 - 4).
Slacken the negative lead pinch bolt and
disconnect the negative (–) battery lead.
Slacken the positive lead pinch bolt and
disconnect the positive (+) battery lead. Battery lead connection
Note:
Upon battery reconnection the
security system will be armed. Opening
any protected entry will sound the alarm.
Make sure that a key or key transmitter is
available.
Caution: Do not overtighten the
pinch bolts.
Clean the battery posts and coat the post
bases with petroleum jelly.
Connect the positive (+) lead, tighten the
pinch bolt and clip the positive terminal
cover on the battery. Connect the
negative (–) lead and tighten the pinch
bolt.
After the battery ha s been reconnected
and the ignition swit ch is turned to
position ‘II’, the message centre display,
if fitted, will initially show an erroneous
reading i.e.––––––. Thiswill remain
until after the bulb check sequence, when
the correct recorded mileage will be
displayed. This is a normal function of the
instrument cluster.
After battery reconnection
After reconnecting the battery:
• Reset the electric parkbrake; refer to Parkbrake on page 4 - 34. • Reset the electrically operated
windows anti-trap function; refer to
Window Anti-trap Protection on
page 4 - 30.
• The trip computer will lose all recorded trip data and all trip
functions will be reset to zero.
The vehicle total odometer reading is
retained.
• If the battery is disconnected for more than 72 hours the radio preset
channels will need to be reset.
• Where fitted, the TV preset channels may need to be reset. Refer to the
Jaguar Touch-screen Handbook.
• Reset the clock to the correct time.
The engine electronic control system
adapts to certain characteristics of the
vehicle. These adaptations are lost if the
battery is disconnected.
On reconnection, therefore, some slightly
abnormal drive symptoms may occur and
the vehicle may need to be driven
10 miles (16 kilometres) or more while
the control system re-adapts.

Maintenance 7 - 17
Windscreen Wipers
Use Jaguar Screen Clean Paste to remove
contamination from the windscreen to
ensure effective wiping or if smearing or
juddering becomes evident. A more
aggressive cleaning agent may be
required to remove stubborn
contamination. Contact a Jaguar Retailer
for advice.
To ensure that the windscreen remains
smear-free, the washer system should be
operated whenever the wipers are used,
even when it is raining.
Windscreen Wiper Blades –
Inspect and Clean
Lift the wiper blades clear of the
windscreen and wipe the blades with a
clean, soft cloth moistened with water to
which a mild liquid detergent has been
added.
Windscreen Washers
The windscreen washer jets are mounted
on the wiper arms.
Note:The windscreen washer jets and
headlight washer jets are not adjustable.

Maintenance 7 - 23
Exterior Care
Note:All the cleaning materials
mentioned in this section are available
from the Jaguar Accessory Range.
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 gr itty 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.
After leaving the car wash, switch on the
windscreen wipers immediately to
remove water and prev ent 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
windscreen 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
windscreen 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 windscreen wipers are kept
in good condition:
Jaguar Screen Clean Paste – Apply to the
exterior of the windscreen only to ensure
effective operation of the windscreen
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:
1. Renew the wiper blades when worn to prevent scratching. Clean the rubber
wiper blades regularly with a mild
detergent solution.
2. It is advisable to clean the windscreen with Jaguar Screen Clean Paste at
regular intervals.
