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.

Roadside Emergency 6 - 15
Dipped beam (outer) headlights
Caution: Halogen bulbs will be
damaged if touched by hand or
contaminated with oil or grease. It is
important to use clean gloves or cloth

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.
