Jaguar S-Type. Service manual - part 37



Automatic Climate Control




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).



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


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



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


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.



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.


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.

• 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 


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 

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 


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