Key transmitter battery renewal
When the battery needs renewal there will be a significant
decrease in the effective range of the key transmitter. To renew
the battery, follow the procedure below:
• Insert a small, flat-blade, screwdriver at an angle of about 45 degrees, into the slot on th e back of the key transmitter
as shown ( A). Apply light pressure to the screwdriver and
lever the screwdriver forward to separate the two halves of
the key transmitter. Finally, pu ll the transmitter from the key
body.
• Insert the screwdriver into th e slot between the transmitter
covers adjacent to the key stowage area as shown ( B).
Apply light pressure to the screwdriver and lever the
screwdriver downward to separate the covers.
• Unscrew and remove the small screw ( C) and remove the
printed circuit board, taking care not to touch the battery
terminals. Remove the battery and dispose of it safely.
• Fit a new battery cell, type CR2032 (available from your
Jaguar Retailer), with the si de marked with the positive
symbol (+) downwards in the battery receptacle.
Avoid touching the new battery as moisture/oil from the
fingers can reduce the life of the battery and corrode the
contacts.
• Replace the printed circuit board making sure to engage the board under the securing tabs (D ), and secure with the
screw.
• Refit the cover and click into place with thumb pressure.
• Slide the transmitter back onto the key body until it clicks
into place.

Warning Lights
Warning lights are arranged within the
instrument cluster.
There are two warning lights, one red,
the other amber, located above the
message centre for primary and
secondary status of the warnings
displayed by the message centre.
‘RED’ warning lights are for primary
warnings. A primary warning must be
investigated immediately by the driver or
a Jaguar Retailer.
‘AMBER’ warning lights are for secondary
warnings when the driver must take
action and then report the fault to a
Retailer at the earliest opportunity.
Other lights within the instrument cluster
indicate system status, such as blue for
main beam and green for direction
indicators, when in operation. Lamp check
A lamp check is initiated when the
ignition is switched ON and lasts for
three seconds (excepting the air bag
warning light which will remain on for
6seconds). Ifany wa
rning light remains
on after this period, investigate the cause
before driving.
Note: Not all lamps are included in the
lamp check, for example main beam
headlights or direction indicators.
Low Oil Pressure (RED)
This lights up with the ignition
switched ON and should go
out once the engine is running.
If the light remains ON once the engine
has started or comes ON whilst driving,
loss of oil pressure is indicated.
STOP the engine immediately and
investigate the cause.
Caution: Do not restart the engine
until the cause of loss of oil pressure
has been identified and rectified.
First check the engine oil level,
seepage7-6.

Starting/Stopping the
Vehicle
When the vehicle is stationary the
automatic gear selector may be left in ‘D’,
‘ 2 ’, ‘ 3’, ‘ 4’ or ‘ 5’, unless the vehicle is to
be parked. When stopping for traffic
lights, junctions etc., either select ‘ P’ or
apply the parkbrake and select ‘ N’.
Before Starting
Before starting the engine, new owners/
drivers should familiarize themselves with
the layout and operation of the controls
and instruments.
!WARNING:
Before attempting to start the engine,
check parkbrake is ON and gear
selector lever is in position ‘P’ or ‘N’.
To Start the Engine
The engine cannot be started until the
gear selector is in ‘ N’ or ‘ P’.
Insert the key into the ignition switch and
turn clockwise to position ‘II’ to switch
on the ignition.
When the key is turned to position ‘III’
the starter motor will turn the engine
until:
• The key is released and automatically returns to position ‘II’.
• The ignition switch is turned to ‘0’ or ‘I’.
• The gear selector is moved out of ‘P’ or ‘N’.
• The engine starts.
If the engine fails to start, the key must be
turned to position ‘0’ before attempting
to restart.
Do not use the starter continuously for
longer than six seconds. Continued use of
the starter will disc harge the battery and
may damage the starter mechanism.
Wait until the engine stops turning before
re-using the starter.
When the engine starts, release the key. The red charge light and the oil pressure
light in the instrument cluster should go
out when the engine is running.
If the engine fails to start
If an ignition key is placed in the ignition
switch and turned to position ‘II’ and the
alarm security light is flashing, it is
possible that the engine will not start.
In any event, please contact a Jaguar
Retailer to investigate the cause of the
light flashing.
It is possible that the fuel system inertia
switch may have tripped, see page 6 - 3
for the resetting procedure.
If the engine persistent
ly fails to start and
flooding is suspected, depress the
accelerator pedal fully, hold it in this
position and turn the key to position ‘III’
for six seconds. Release the key, remove
your foot from the accelerator pedal and
then attempt to restart the engine.
Note: The engine cannot start whilst the
pedal is fully depressed, it must be
released to enable the engine to start.
If the engine still fail s to start, switch the
ignition OFF and contact a Jaguar
Retailer.

Catalytic Converters
A few precautions on the use of vehicles
fitted with catalytic converters are
necessary. These are:
1. In order to maintain the efficiency of the emission control system it is
essential that unleaded fuel is used.
Use of leaded fuel will seriously
damage the catalytic converters.
2. Heavy impact on the converter casings must be avoided.
3. The engine settings must not be altered; they have been established to
ensure that the vehicle will comply
with stringent exhaust emission
regulations. Incorrect engine settings
could cause unusually high catalytic
converter temperatures and thus
result in damage to the converter and
vehicle. If adjustment to the settings is
considered necessary, this should be
performed by a Jaguar Retailer. 4. A correctly tuned engine optimises
exhaust emissions, performance and
fuel economy and it is recommended
that the vehicle is regularly
maintained.
5. Do not continue to operate the vehicle if any engine malfunction is evident;
malfunctions should be rectified
immediately. For instance, misfire,
loss of engine performance, excessive
oil consumption or engine run-on may
lead to unusually high catalytic
converter temperatures and may
result in damage to the converters and
vehicle.
6. The use of catalytic converters increases exhaust system
temperatures, therefore, do not
operate or park the vehicle in areas
where combustible materials such as
dry grass or leaves may come into
contact with the exhaust system. 7. Do not run the engine with either a
spark plug lead disconnected or a
spark plug removed. Do not use any
device that requires an insert into a
spark plug hole in order to generate air
pressure e.g. tyre pump, paint spray
attachment etc., as this could also
result in catalyti c converter damage.
8. The vehicle is designed for normal road use. Below are examples of abuse
which could damage the catalytic
converters and vehicle. These may
lead to a dangerous condition due to
excessively high catalytic converter
temperatures.
• Competition or off-road use.
• Excessive engine speed.
• Overloading the vehicle.
• Switching off the engine whilst in gear.

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.

Maintenance 7 - 19
Wear
All tyres fitted as original equipment
include tread wear indicators (TWI) in
their tread pattern. When the tread has
worn to a remaining depth of 1.6 mm the
indicators appear at the surface as bars
which connect the tread pattern across
the full width of the tyre.
It is illegal, in certain countries,
to continue to use tyres after the tread
has worn to less than 1.6 mm over three
quarters of the width and the entire
circumference of the tyre.It should be noted that the properties of
many tyres alter progressively with wear.
In particular the ‘wet grip’ and
aquaplaning resistance are gradually but
substantially reduce
d. Extra care and
speed restriction should therefore be
exercised on wet roads as the effective
tread depth diminishes.
Incorrect wheel alignm ent will accelerate
tyre wear. Fins on the inner or outer
edges of the tread pattern are caused by
excessive toe-in or toe-out respectively.
As fins may also be caused by high
cornering speeds or road camber, it is
advantageous to have the cause detected
by having the wheel alignment checked.
Tyre repair
It is recommended that damaged tyres
are discarded and new tyres fitted.
They must not be repaired in view of the
high performance capability of the
vehicle. Damage
Excessive local distortion can cause the
casing of a tyre to
fracture and may lead
to premature failure. Tyres should be
examined especially for cracked walls,
exposed cords, etc. Flints and other sharp
objects must be removed from the tyre
tread; if left in they may work through the
cover. Clean off any oil or grease
contamination by using a suitable
cleaner.
Caution: Do not use paraffin
(kerosene), because this has a
detrimental effect on rubber.
Tyre use after vehicle storage
After a long period of a vehicle standing,
tyres may become locally distorted with a
flat area. This will cause an uneven ride
for a few miles until the tyres have
warmed up and the ‘flat’ rounds off.
However, to reduce the effects of
flat-spots, the tyres of a stored vehicle
may be inflated to pressures not
exceeding 60 lbf/in² (4.2 bar, 420 kPa,
4.3 kg/cm²).
