On the Road 4 - 59
General Driving
Information
!WARNING:
Ensure the parkbrake is on and the
automatic gear selector is in
position ‘P’ or ‘N’ before attempting
to start the engine.
Before driving off, check the gauges and
warning lights and messages. Take special
note of any warning light that is on.
Seat belts are provided for your safety
and it is unwise, and in certain countries
illegal, to commence any journey,
however short, without wearing them.
Warming Up
Do not operate the en gine at high speed
when first started but allow time for the
engine to warm up and the oil to
circulate.
Engine Braking On Downhill
Gradients
When driving on mountain roads with
long downhill gradients it is advisable to
select a low gear.
Running-in
Apart from a few precautionary
recommendations, there are no strict
‘running-in’ procedures for this vehicle.
By observing the following advisory notes
you will ensure maximum engine,
transmission and brake life for your
vehicle:
1. Allow the engine to warm up thoroughly before operating at engine
speeds over 3500 rev/min.
2. Vary the speed frequently.
3. From 940 miles (1500 kilometres) onwards, gradually increase
performance of the vehicle up to the
permitted maximum speed, where
road conditions permit. Running-in for brakes
To ensure that the brake pads can
‘bed-in’ evenly and reach their optimum
wear and performance condition, usually
within 300 miles (480 kilometres),
the following points are recommended.
1. Where possible, avoid heavy braking
or rough usage of the brakes as this
can result in damage being caused to
the brake pads and discs.
2. Avoid prolonged use of the brakes, for example, when descending severe
gradients.
3. Frequent light application of the brakes is desirable. This helps to fully
‘bed-in’ the brake pads before the
normal running-in period is
completed and the vehicle is operated
at high speeds, when maximum brake
efficiency will be required.
The above equally applies when new
discs or pads have been fitted.
7-18 Maintenance
Tyres
Tyres of the correct type, manufacturer
and dimensions, with correct cold
inflation pressures are an integral part of
every vehicle’s design. Regular
maintenance of tyres contributes not only
to safety, but to the de signed function of
the vehicle. Road-holding, steering and
braking are especially vulnerable to
incorrectly pressurised, badly fitted or
worn tyres.
Tyres of the correct size and type, but of
different make have widely varying
characteristics. It is therefore
recommended that Jaguar approved tyres
are fitted to all wheels.
A tyre recommendation placard is placed
on the inside of the fuel filler flap, giving
information specific to the vehicle’s
wheel and tyre equipment.
Always ensure that the wheel nuts are
fully seated before finally tightening the
nuts in alternate sequence.
W, Y and Z-rated performance tyres are
optimised for driving dynamics and have
limited winter traction ability. Compared
with H-rated all-season tyres, they may
incur increased tread wear, reduced ride
comfort, and increased road noise.
Tyre Renewal
When renewing tyres, it is preferable to
fit a complete vehicle set. If either front
or rear tyres only need to be renewed,
new tyres must be fitted, as axle sets,
to replace worn ones. After new tyres
have been fitted the wheels need to be
dynamically balanced. The radial ply
tyres specified are designed to meet the
high-speed performance capability of this
vehicle (see page 8 - 7) . Do not fit tyres
with a different tread pattern, size or
speed rating.
Tyre Pressures
The recommended tyre pressures are
written on a label, inside the fuel filler
flap. These tyre pressures provide
optimum ride and handling
characteristics for all normal operating
conditions. The pressures should be
checked, and correctly set each week
with the tyres cold. Tyre temperatures
and pressures increase when running.
Deflating a warm tyre to the
recommended pressure will result in
under inflation whic h may be dangerous.
A slight natural pressure loss occurs with
time. If this exceeds 2 lbf/in² (0.14 bar,
14 kPa, 0.14 kg/cm²) per week, the cause
should be investigated and rectified.
Note: It is an offence in certain countries
to drive a vehicle with tyres that are not
inflated in accordance with the vehicle’s
proper use.
