Jaguar S-Type. Manual - part 37

Automatic Climate Control

156

RAM AIR

With the climate control system switched
off, air recirculation is automatically
selected (intake flap closed). To select
fresh air with the system off, press one of
the air distribution buttons.

With the blower switched off, the fresh
airflow results from the forward motion of
the vehicle (ram air effect).

WARNING:

Selecting ram air (or switching the
system off when the windows are
closed) may increase the possibility of
screen misting due to reduced airflow.

Inertia Switch

Roadside Emergency

LOCATING THE INERTIA
SWITCH

In the event of an accident, an inertia
switch may trip, isolating fuel pump
operation. Once the switch has tripped it
must be reset before attempting to restart
the engine.

The inertia switch is located behind the
trim on the left-hand side of the vehicle,
forward of the front door post, below the
facia. A finger access hole in the trim
allows the driver to reset the switch.

Resetting the switch

WARNING:

To avoid the possibility of fire or
personal injury, do not reset the inertia
switch if you see or smell fuel.

If no fuel leak is apparent, reset the inertia
switch as follows:

1. Turn the ignition switch to position 0.

2. Press down the rubber reset button

on the top of the inertia switch.

3. Turn the ignition switch to position II,

pause for a few seconds, then return
the key to position 0.

4. Make a further check for fuel leaks.

Emergency Starting

Emergency Starting

ROLLING START

If the electric parkbrake was applied
before the battery was discharged (e.g.
vehicle unused for a long period), it will
not be possible to release the parkbrake.

Do not push or tow start a vehicle with
automatic transmission, even with the
parkbrake released. With a discharged
battery it will also not be possible to move
the drive selector from the P position.

WARNING:

A vehicle start by pushing or towing
must not be attempted. Only jump lead
starting, or the fitting of a fully charged
battery is recommended.

USING JUMP LEADS

Both the booster and discharged battery
should be treated with great care when
using jump leads. Always use high quality
leads capable of carrying the starter
current of the vehicle to be started.

Before commencing, the following
precautions must be taken:
• When the battery of another vehicle is

being used, make sure that the
vehicles do not touch. Alternatively,
remove the charged battery and place
near to, not on, the vehicle with the
discharged battery.

• Make sure that both vehicles have all

electrical services OFF, the
parkbrakes applied and neutral
(manual transmission) or P (automatic
transmission) selected.

• Where the jump leads are of a

different colour, e.g. red and black,
use red for positive (+). This aids
identification and helps to avoid
crossing positive (+) to negative (–).
Take extra care to avoid crossing the
polarity when using cables of the
same colour.

Caution:
• If using a jump start vehicle, under

no circumstances should the
vehicles come into contact with
each other. This could establish an
earth connection, which may cause
sparks and damage.

• Do not run the jump start vehicle’s

engine when boost starting a
Jaguar vehicle. If the jump start
vehicle’s engine is running and the
jump leads are disconnected,
damage to the Jaguar vehicle’s
electrical system will result.

• The booster battery must be of the

12-volt type.

To gain access to the battery, fold the
luggage compartment floor panel
forward. If a space saver spare wheel is
fitted, it will be necessary to remove the
under floor stowage tray.

Emergency Starting

Procedure for using jump leads

The following procedure must be followed
exactly, being careful not to cause sparks:

1. Unclip the battery positive (+) terminal

cover.

2. Attach one end of the red jump lead to

the positive (+) terminal of the booster
battery and the other end to the
positive (+) terminal of the discharged
battery. Make sure that a good
connection is made.

Caution: Do not connect the negative

jump lead directly to the negative
(–) terminal of the discharged
vehicle.

3. Attach one end of the black jump lead

to the negative (–) terminal of the
booster battery and the other end to
an earth point on the vehicle being
started. (If your Jaguar has the
discharged battery use only the spare
wheel locking stud, as shown.) The
ground connection point must be at
least 30.5 cm (12 inches) from the
discharged battery. Make sure that a
good connection is made.

4. When started, allow the engine to idle

for five minutes before disconnecting
the cables.

5. Disconnect the black jump lead from

the earth point and the booster
battery negative (–) terminal.

6. Disconnect the red jump lead from the

positive (+) terminals of both batteries.

7. Refit the positive (+) terminal cover.

8. Refit the luggage compartment floor

panels.

After starting the engine, it may be
necessary to reset the electric parkbrake
(refer to page 128). See also After battery
reconnection, page 196.
