Introduction
The Jaguar S-TYPE is an all-new, luxury sports sedan with a distinctive style, refined power, agile
handling, supple ride and luxurious comfort.
Powertrains are a V8 (AJ28) petrol engine, derived from the engines currently used in XJ and XK Series
vehicles, with a new five-speed automatic transmission or alternatively, a V6 (AJ-V6) petrol engine
coupled with either a five-speed automatic transmission or a five-speed manual transmission. The new
V6 engine and transmission units and the updated variations to the V8 engine are described in the
ÔJaguar S-TYPE Powertrain IntroductionÕ Technical Guide, which compliments this Guide.
As with current vehicles, variable rate steering control is fitted and all vehicles have ABS brakes with
traction control as standard. A new, optional feature with the Jaguar S-TYPE is Dynamic Stability Control
(DSC), yaw control, which assists the driver in maintaining directional control of the vehicle.
Unlike current vehicles, the hood is hinged at its rear with a safety catch provided at the front of the
hood. A tilt and slide sliding roof with a sunshade is an optional feature.
Both front seats have electrically operated 8-way adjustments as standard and memory equipment is
available as an option. To allow a greater load to be carried in the luggage compartment, the rear seats
can be folded forwards and are split in a 60/40 configuration.
Automatic climate control, with dual temperature control for the driver and front passenger, is a
standard feature on all vehicles. Another new item is reverse park control, a system giving the driver
audible warning of obstructions which could damage the vehicle during reversing.
A standard fit radio/cassette unit provides in-car entertainment with a CD autochanger also being
offered. Other options include a phone, navigation system, vehicle emergency monitoring system and
certain voice activated systems. Optional cruise control and audio switches are fitted to the steering
wheel. All vehicles have a trip computer system and a message center.
Security features are immobiliser and alarm. Optional features include intruder sensor and inclination
sensor. The 3 or 4 button key-ring transmitter has radio frequency operation with an encrypted rolling
code to help prevent theft of the vehicle.
Standard Corporate Protocol (SCP) is the only computer system highway for all the vehicle electronic
controls, CAN is not used.

Cool Air Inlet
The climate control air intake is through a plastic
moulding attached to the engine compartment
bulkhead. This moulding contains the air/pollen
filter and is provided with water drains. It is
covered by a leaf screen. The air intake cover is
held on with a two piece plastic fastener (see
illustration).
D.501.1788
Trunk
The steel trunk lid has two hinges with one
damper and covered springs to assist lid lift. The
lid can be released using the switch on the fascia,
using the key-ring transmitter, or, if the vehicle is
unlocked, by a release button on the lid. An
emergency lock, key operated, is provided for
access to the trunk if, for instance, the battery is
disconnected. The trunk lock barrel is mounted to
the trunk lid with two flange nuts. Drive to the
trunk latch is via a cable which is a snap fit to the
rear of the barrel. Trunk sealing is a simple flange
mounted bulb section with a single moulded joint.

System Overview
The climate control system provides filtered air to
the cabin from a fully automatic, dual zone,
temperature controlled system. Driver and front
passenger have independent control of the
temperature of the air for their individual
comfort. The system regulates the volume of
airflow from the vents of the instrument panel,
rear seat panel, front and rear floor ducts, front
screen defroster and side windows. It will
automatically select between fresh and
recirculated air to assist rapid cooling of the
interior.
Operation of the heated front screen or heated
wiper park area and rear window heater is
controlled from the climate control panel. Door
mirror heaters are automatically switched on
when the heated rear window is switched on. As
with current vehicles, the outside air temperature
can be displayed in either Celsius or Fahrenheit.
The system can be switched ON by pressing any
button, except OFF.
When ÔAUTOÕ is selected, the driverÕs and front
passengerÕs air temperature, fan speed and air
distribution are automatically controlled to give

JAGUARS-TYPEClimate Control
64Control Panel
The control panel is a combined unit
incorporating the air conditioning control module
(A/CCM).
Heater/Evaporator and Blower
A single blower, heater and evaporator are fitted
to the passenger side of the vehicle behind the
fascia. Air intake is from the passenger side via
leaf screen slots (see page 16). A particle filter is
mounted forward of the bulkhead in a rain/water
collector box. Mounting of the heater/evaporator
unit and blower assembly is by three bulkhead
fixings and one locator pin.
Condensate drainage is integral with the
heater/evaporator unit and therefore has no
separate drain tubes. The heater matrix is a dual
heater unit with three heater pipes, two inlets of
16mm diameter and one outlet of 19mm
diameter.
D.412.217
Underbonnet Components
Both V6 and V8 engine configurations include a
water valve controlled heating (dual) system and
the valve is mounted behind the right-hand side
headlamp. The V8 engine system, as with current
cars, has a water pump to supplement idle water
flow through the heater and this is mounted on
the right-hand side of the cooling pack. The pump
is held in a mounting rubber, which is pushed
over two pillars on the rear of the fan shroud and
held with two screws.
Condenser
The black-painted aluminium condenser is located
to the front of the combi-cooler and mounts to its
end tanks. The condenser end tubes push into two
grommets, which are in turn held in two steel
brackets, screwed to the radiator end tanks. The
bottom of the condenser is screwed directly into
the radiator tanks. A radiator cooling duct clips
onto the condenser end tanks and also pushes
onto the lower radiator channel. The duct ensures
that all available airflow is directed through the
cooling module.

The suction hose and liquid line are a one-piece
assembly. A single screw connects them to the air
conditioning unit manifold at the bulkhead. A
further screw fixing and push-in clip secures them
at the side of the engine bay. The liquid line fixed
to the cooling module then joins with a block
fitting and the suction hose connects with a quick
connect fitting and routes across the underneath
of the cooling module to the compressor. The
compressor suction and discharge hoses are also a
one piece assembly.
A pressure transducer is fitted to the discharge
hose as it connects to the rear of the condenser.
The high side charge port is situated on the
manifold connecting to the receiver drier whilst
the low side is adjacent to the compressor behind
the LH front wheel.
The compressor is a 9Occ scroll, which is variable
from 100% to 30%. Compressor is standard
specification to all vehicles although package
makes them unique to V6 and V8.

current XJ and XK Series.
System refrigerant is R134a. Vehicle charge weight
is 800 gms and charging is through the high side
charge port only.
Oil type is WSH-MIC231-B and refill quantity is
180 cc -220 cc.
Special tools are hose clamp pliers and air-
conditioning hoses spring lock de-coupler.
General information
Ensure that the grille at the base of the windshield
is kept clear of leaves, snow or other obstructions.
A solar sensor is mounted on top of the fascia, in
the centre of the defrost grille, and this should not
be covered.
The air conditioning system should be run briefly
at least once each week with a cold setting to
prevent the seals from drying out with subsequent
refrigerant leaks.
When the engine and vehicle interior are cold the
fan speed may be low until the engine has warmed
up, this avoids excessively cold air being blown
into the cabin.

68Heated wiper park or (where optionally fitted)
heated front screen.
With the engine running, due to the high current
draw, press to switch on the heated wiper park to
defrost the wiper park area, or where fitted, press
to switch on the heated front screen for rapid
defrost/demist.
Heated wiper park automatically operates in cold
weather, and may stay on continuously. It is
automatically switched on when ÔDEFROSTÕ is
selected. If manually selected, the heated wiper
park will automatically switch off after 10
minutes.
Heated front screen is automatically switched on
when ÔDEFROSTÕ is selected. It will automatically
switch off after 4 minutes. The heaters will switch
off, or not operate, if low battery voltage is
detected.
Heated Rear Screen
With the engine running due to the high current
draw, press to switch on the heated rear screen
for rapid defrost/demist. The rear screen heater
will be automatically switched off after 10
minutes.
In cold conditions, the heated rear screen
operates automatically. Selecting ÔDEFROSTÕ will
also turn the heated rear screen ON. The heaters
will switch off, or not operate, if low battery
voltage is detected.
Air Distribution
Air distribution is automatically controlled when
ÔAUTOÕ is selected. Manual control can be
achieved using the air distribution buttons.
Heat at Rest Feature (V8 engine vehicles
only)
Interior heating may be continued after the
engine has been switched off by turning the
ignition to position ÔIIÕ. The climate control system
will continue to provide heat to the vehicle
interior until the engine cools down. Excessive use
will cause a low battery voltage, which may
prevent the vehicle from being started.
Voice Activated Control
Some functions of the climate control system can
be operated with the Voice Activation System
(when fitted).
A full operating description is given in the Voice
Activation Handbook included with the vehicle
literature pack.
