Jaguar S-Type. Service manual - part 35



Fuel and Refuelling



Jaguar fully supports all efforts to protect 
and maintain ambient air quality and 
encourages the use of reformulated 
gasoline, where available.




Exhaust system temperatures can be 
extremely high - DO NOT park on 
ground where combustible materials 
such as dry grass or leaves could come 
into contact eith the exhaust system - 
in dry weather as a fire could result.

Caution: Catalytic converters can be 
easily damaged through improper use, 
particularly if the wrong fuel is used, or 
ifan engine misfire occurs. For this 
reason it is VERY IMPORTANT that you 
heed the precautions which follow:
• In order to maintain the efficiency of 

the emission control system it is 
essential that the correct fuel is used. 
If the vehicle is fitted with a gasoline 
engine, never refuel with leaded fuel: 
this will seriously damage the catalytic 

• Heavy impact on the converter 

casings must be avoided.

• A correctly tuned engine optimises 

exhaust emissions, performance and 
fuel economy. It is recommended that 
the vehicle is regularly maintained.

• The engine settings must not be 

altered; they have been established to 
ensure that the vehicle will comply 
with stringent exhaust emission 

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 Dealer.

• 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.

• Do not run a gasoline 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. tire pump, paint 
spray attachment etc., as this could 
also result in catalytic converter 

• The vehicle is designed for normal 

road use. Below are examples of 
abuse which could damage the 
catalytic converters and vehicle:

Competition or off-road use.

Excessive engine speed.

Overloading the vehicle.

Switching off the engine whilst in 

These may lead to a dangerous 
condition due to excessively high 
catalytic converter temperatures.

Do not disconnect any pipes in the air 
conditioning refrigeration system. A 
refrigerant is used which can cause 
blindness if allowed to contact the 
eyes. If refrigerant should contact the 
eyes or skin, wash the eyes or affected 
area with cold water for several 
minutes. Do not rub. As soon as 
possible thereafter, obtain treatment 
from a doctor or eye specialist.


The cabin is supplied with filtered air from 
a fully automatic electronic climate 
control system, which also provides 
individual selection of temperature (dual 
zone) by the front occupants.

The system can be overridden by manual 

The climate control panel is located in the 
center console above the radio and audio 
controls. There are two variants:
• A dedicated control panel with LCD 

(Liquid Crystal Display) screen, refer 
to page 152.

• A multi-function touch control and 

display unit, shared with navigation 
and other systems (see the 
touch-screen display handbook).


Automatic climate control

Automatic climate control provides 
efficient regulation of the vehicle 
environment without constant 
adjustments from the occupant.

Sensors inside the vehicle monitor 
temperature, humidity and direct sunlight. 
In response, the electronic control system 
automatically adjusts the heat output, 
blower speed, air intake and airflow 
distribution, so as to maintain the 
selected temperature(s) and reduce 

Automatic operation provides optimum 
comfort under most driving conditions.

It is recommended that automatic 
control (AUTO) is selected as the 
normal operating mode.

Use of air conditioning

Air conditioning is an integral part of the 
climate control system, providing cooled 
and dehumidified air for occupant 
comfort; the dry airflow is also effective in 
preventing misting of the windows.

While the air conditioner can be manually 
switched off, it is recommended that it is 
used in all climatic conditions throughout 
the year, preferably in AUTO mode.

Close all windows and the sunroof when 
the air conditioning is on to ensure 
satisfactory operation.

Note: When air recirculation is selected, 
the sound of the airflow will change: this is 

Climate Control



Use of air recirculation

The air conditioner and heater system is 
supplied with fresh air via an intake flap.

Closing the flap causes the air inside the 
vehicle to be recirculated. This helps to 
prevent unpleasant odours from being 
drawn into the vehicle and also to improve 
the performance of the air conditioner in 
very hot conditions. However, the use of 
recirculated air will cause screen misting 
after a short period and should only be 
used as necessary.

In AUTO mode, the air intake flap is 
controlled automatically. If required, air 
recirculation may be manually selected 
for either a short or indefinite period.



To prevent humidity build up inside the 
vehicle and possible screen misting, 
avoid driving with the air conditioning 
system off, or in manual air 
recirculation, for prolonged periods.


To make sure of the satisfactory operation 
of the climate control system, note the 
following points:
• Make sure that the external grille at 

the base of the windshield, which 
provides fresh air for the climate 
control system, is kept clear of leaves, 
snow or obstructions.

• A solar sensor is mounted on the 

center top of the facia, (as shown on 
the next page) (1). Ensure that this 
sensor is not covered.

• Temperature and humidity sensors 

are located behind the small grille (2), 
(as shown on the next page). Do not 
cover or obstruct the opening.

• Air ducts under the front seats supply 

the rear passenger footwells (as 
shown on the next page). Objects or 
materials placed under the seats may 
block or obstruct the open ducts.

• The external air intake to the air 

conditioner and heater system is fitted 
with a filter. Make sure that the filter is 
changed at the specified service 
intervals to maintain efficient 

• If the air conditioning system is not 

used frequently, it should be run 
briefly at least once each week, with a 
cold setting, to prevent the seals from 
drying out with subsequent refrigerant 

• Moisture removed from the air by the 

air conditioning unit is discharged 
onto the road underneath the vehicle. 
After stopping, puddles of water may 
form underneath the vehicle. This is

The illustration above shows the location 
of the air vents within the vehicle. The 
airflow from the facia face level vents is 
regulated using thumbwheel controls and 
adjustable direction vanes.

Air distribution between the windshield, 
facia and floor levels is selected 
automatically when operating in AUTO 
mode but can be selected manually.
