Seats
All seats are completely new to Jaguar with no
commonality to previous models.
Front Seats
The drivers seat and front passenger seat are
electrically adjustable for front and rear seat
height, fore and aft movement and squab tilt with
optional lumbar adjustment. Optional heated
cushions and squabs may be fitted with the heater
switches located on the centre console. The head
restraints are manually adjustable for height (four
positions) and tilt. The drivers seat also has an
optional two position memory facility. Side airbags
are fitted to both front seat squabs (see Occupant
Protection section).
Seat Construction
The seat track assembly consists of two slider
rails, cross mounted drive mechanisms and anelectrical harness sub-assembly. The seat cushion
pan is supported on four brackets attached to the
height adjustment drive actuators. Two separate
drive motors and screw actuator mechanisms
provide raise/lower movements respectively for
the front and rear of the cushion. The seat fore
and aft motor and drive shaft are located across
the front of the track assembly: note the drive
shaft must not be used to lift the seat assembly
when fitting or removing a seat. Each drive has a
potentiometer to register the selected position for
memory storage.
The track assembly wiring harness and driver seat
control module (DSCM) (driverÕs side only) are
fixed to a plastic tray which clips onto the frame.
The squab frame is a welded steel construction
which bolts to the track assembly and carries the
recline drive, lumbar support mechanism and a

Restraints Control Module (RCM)
The RCM:
¥ Houses the electro-mechanical safing sensor
and electronic discrimination sensor which
detect a frontal impact.
¥ Houses the electronic safing sensor to detect
a side impact.
¥ Identifies severity and direction of impact
and makes decision on deployment of airbags
and pre-tensioners.
¥ Provides firing signals to all airbags and pre-
tensioners.
¥ Performs on board testing of the airbag and
pretensioner firing circuits, warning indicator
circuits and module status (Side Impact
Sensor performs its own internal checks).
¥ Stores fault codes in non-volatile memory.
¥ Drives the airbag warning lamp on the
instrument pack: if the warning lamp is
faulty (fault code recorded) an audible
warning tone is sounded.
¥ In the event of an impact, sends a signal to
the vehicle emergency message system
(VEMS) and the PCM to indicate that a crash
has occurred.
¥ Is connected to the data link connector via
the SCP data bus to enable communication
with an external PDU or scan tool.
¥ Provides temporary back-up power to operate
the airbags in the event of loss of battery
supply in an impact.
¥ In the event of an impact, records certain
data for subsequent access via the data link
connector. This data includes deceleration
information, firing delay and fault codes.
The RCM is bolted to the top of the driveshaft
tunnel below the center stack. Due to the
importance of the module being securely fixed to
the vehicle body, the ground connection is made
via the fixing bolts and is monitored by the
diagnostic system. A bad connection causes a fault
code to be generated.

the figures given in the JTIS Service instructions
must be adhered to. RESTRAINTS CONTROL MODULE

Note:An impact at an oblique angle may cause
both frontal and side airbags to deploy, depending
on how much lateral acceleration is sensed.

JAGUARS-TYPEFuel System

Introduction
The fuel tank components, operation and layout
are new to Jaguar and have no commonality with
previous systems. The major features of the fuel
delivery system are the use of a saddle type tank
and a returnless fuel system. The evaporative loss
management system is similar in operation to that
fitted to the XJ and XK Series vehicles and on-
board refuelling vapour recovery (ORVR) is a
standard feature. For NAS markets only, leak test
diagnostics are performed.
Returnless Fuel System
The returnless fuel system delivers the correct
amount of fuel to the engine under all conditions
and at a constant pressure differential with
respect to manifold pressure. This is without the
need for a return line to the tank or a fuel rail
pressure regulator. The use of a return line and
the pressure drop across a regulator contribute to
vapour formation which can affect fuelling
calibration and requires a complex vapour
management system to meet legislative
requirements. Elimination of these components,
D.310.047
together with closed loop control of the variable
speed fuel pump, causes a reduction in the vapour
generated, lower fuel temperatures and better fuel
pressure control. Additional advantages include a
reduced load on the electrical system and
improved fuel economy.
Fuel Tank
The fuel tank is of the ÔsaddleÕ type shape with LH
and RH fuel compartments and is constructed of
high density polyethylene (HDPE), a plastic blow
moulded material. The tank is located below the
rear passenger seat with the drive shaft and
exhaust running through the arch of the tank. The
underside of the tank is protected by a fitted heat
shield and the tank assembly is retained by two
metal straps which are fixed to the underbody at
the front by removeable hinge pins and at the rear
by bolts.
Refuelling is via a separate filler pipe and
connecting hose to a stub pipe on the RH fuel
compartment.
A fuel pump module is located in the RH

INERTIA SWITCH operating fuel level sender assembly mounted on
the respective module assembly.
Control and Operation
The speed of the fuel pump is varied under closed
loop control so as to deliver the required fuel rail
injection pressure in accordance with factors such
as driver demand, manifold pressure and
temperature changes. The control loop sensors,
providing feedback information to the powertrain
control module (PCM), are the engine fuel
temperature (EFT) sensor and the injection
pressure (IP) sensor which are both mounted
directly on the engine fuel rail (see
S-TYPE Powertrain Technical Guide). The IP sensor
also has a vacuum feed from the intake manifold
so as to measure the pressure differential.
The required fuel flow is determined by the PCM
and sent to the rear electronic control module
(RECM) which is the power driver for the fuel
pump. The PCM demand to the RECM is a pulse
width modulated (PWM) signal over a single line
at a frequency of approximately 256 Hz and a
duty cycle of 0-50%. The RECM effecively
amplifies this signal by increasing the frequency
by 64 and doubling the duty cycle, thus providing
the necessary high current drive for the fuel
pump. The fuel pump relay, located in the rear
power distribution box, is energised by the PCM
relay and provides a dedicated fused supply to the
RECM for the pump drive.
When the ignition switch is turned from OFF to
RUN or START, the PCM primes the system by
running the pump for 1 second at full speed. The
pump is switched off 1 second after the engine is
stopped. During hot starts, fuel pressure is
increased to prevent vapour lock.
Fuel pump drive status is monitored by the RECM
and communicated to the PCM via the SCP
network.
Outputs from the fuel senders are connected by
independent wires to the RECM which sends the
data to the instrument pack and the PCM.
Inertia Switch
The inertia switch is located behind the trim on
the left side of the vehicle, forward of the front
door post and below the fascia. A finger access
hole in the trim allows the switch to be reset.

Autolamps Delayed Exit (A)
This feature leaves the headlamps turned on after
the ignition has been switched off, allowing the
driver and passengers increased visability on
leaving the vehicle. The switch has seven positions
and varies the time from three seconds up to
three minutes. After adjustment, the newly set
delay time will be displayed on the message
center.
Auto (B)
A light sensor on top of the instrument panel,
monitors exterior light levels and automatically
switches the side lamps and dipped headlamps on
or off. When light fades to the non-adjustable
preset level, the sidelamps and headlamps switch
on automatically. As light increases to the preset
level, the sidelights and headlamps switch off
automatically.Rear Fog Lamps (F)
Turn the switch to headlamps on, pull the switch
and then turn to position (F). Turning on the rear
fog lamps will also turn on the front headlamps.
Front Fog Lamps (G)
Pull the switch in positions (A), (B), (D) or (E) to

the rotary switch is turned off (C) the switch will
be retracted to its normal position and the fog
lamps will be turned off.
Daylight Running Lamps
In certain countries it is a legal requirement for
the lamps to be on during the hours of daylight.
With the rotary switch in the off position (C),
dipped headlamps, sidelights and tail and number
plate lamps will switch on automatically when the
ignition is turned to position II, the vehicle is out
of park (automatic transmission only) and the
parking brake is released.
Battery Saver
If the dipped or main beam headlamps are
switched on and the ignition is turned to OFF or
the key is removed, the lamps will automatically
turn OFF after 10 minutes. The sidelights will
remain ON.
Bulb Failure Monitoring
The tail and brake lamp bulbs are monitored for
failure and a corresponding message is shown in
the message center, e.g ÔLEFT TAIL LAMP FAILEDÕ.
There are two tail lamp bulbs in each tail lamp.
The message that a tail lamp has failed indicates
that both bulbs in that cluster have failed. The
message will be shown, even after a bulb is
replaced, until the next time the bulb is switched
on.

STEERING COLUMN ADJUSTMENT
SWITCH NAS COMPASS ZONESSteering Column Adjustment Switch
The steering column can be adjusted for tilt and
reach by operating the four-way control switch on
the steering column. Moving the switch forwards
and backwards controls steering column reach.
Moving the switch up and down controls tilt. The
selected position is recorded by the memory
feature (where fitted).
Entry/Exit Mode (where fitted)
Entry/exit mode is selected by setting the steering
column adjustment switch to the ÔAutoÕ position.
When the key is removed from the ignition switch,
the steering column will move to the tilt away
position, which is its uppermost tilt and innermost
reach position. The seat will move rearwards. This
gives the driver maximum room entering and
exiting the vehicle. The steering column position,
before Ôtilt awayÕ, is memorized. When the
ignition key is next inserted in the ignition switch,
the steering column and seat will move back to
their programmed position.

System Description
The security system is controlled by a driver door
control module (DDCM). When activated
unauthorized entry in to the vehicle is detected by
the courtesy lamp switches. When the alarm is
triggered, the system flashes the turn signal lamps
and sounds the alarm system horns.
The passive anti-theft system (PATS) is a feature to
prevent the vehicle being driven away by an
unauthorized person. The PATS system consists of
electronically coded keys, a transceiver and is
controlled by the Instrument Pack. When the
ignition is switched to position ÔIIÕ, the transceiver
energises the ignition key to read its electroniccode that is transmitted back. If the read code
equals a stored code in the control module, the
steering column is unlocked and the powertrain
control module (PCM) will let the engine start.
Otherwise, starting of the engine is disabled
(through the starter disable relay and the PCM).
The security indicator LED provides the driver
with the status of the PATS or security system. If
the security system is armed the light will flash
when the ignition is switched OFF. The PATS light
will illuminate when the key is inserted into the
ignition lock and turned to position ÔIIÕ. It will stay
illuminated until the system has carried out its test
on the key. If the system detects a fault, it will
flash the LED for 1 minute, and then flash out the
corresponding 2 digit fault code.

Head Unit, there is no remote control. Antennas
are integrated into the front and rear bumpers.
Harnesses for the TV are incorporated in all
Japanese vehicles.
Jaguar Assist (North America only)
Assist is an integrated vehicle emergency message
system (VEMS) that uses the Jaguar security
response center for emergency roadside
assistance via the Jaguar in-car telephone
installation. The global positioning system (GPS) is
used to identify the position, direction of travel
and speed of the vehicle. Access to the Assist
feature is through the use of the Navigation
system. The emergency assistance feature allows
rapid access to the emergency services (police,
fire or ambulance) and roadside assistance. Once
assistance has been requested and the vehicle
location confirmed, the appropriate services are
contacted for assistance to be dispatched. In the
unfortunate event of an airbag deployment, the
system will automatically place an emergency call.
Access to the system is gained by pressing the
information button on the Navigation front panel
screen (the ignition must be in position ÔIÕ or ÔIIÕ).
While in use, a sequence of messages is displayed
on the LCD.
Note: If an Assist call is initiated and the operator
cannot establish voice communication, police
assistance will be dispatched to the vehicle.
The system can be used wherever a cellular
phone service is available. The Jaguar phone must
be connected to the vehicle, working correctly
and registered with a cellular network. A roaming
airtime agreement is required so that the system
can be used in all areas.
Diagnostic Light
A diagnostic light is integrated into the
information (ASSIST) button. The diagnostic light
flashes throughout an activation but stays on
continuously when a failure is detected. A
message is given on the display: ÔASSIST
FAILUREÕ. There are four potential failure modes:
1. No VEMS menu is displayed when the
information ASSIST button is pressed
2. No activation is performed when the enter
button is pressed to make a selection3. VEMS is unable to compute the location of
the vehicleÕs current position
4. The Navigation system is unable to display
any VEMS messages or would display the
wrong VEMS messages.
Real Time Traffic Information (RTTI)
In the UK the provider for RTTI is ÔTrafficmasterÕ.
Information is collected from their own unique
network of infra-red road sensors which monitor
the average speed of traffic. This information is
sent by radio data link to TrafficmasterÕs
operational headquarters. After processing and
editing the information, it is transmitted in real
time, in words and graphics to Trafficmaster
control modules installed in vehicles. RTTI will not
be available on early vehicles but could be Dealer
fitted retrospectively.
Other markets will use different traffic congestion
information services which will depend on market
infrastructure and service provider support. Japan
will use the ÔVehicle Information and
Communications SystemÕ (VICS).

Using the System
Initialization
When the ignition switch is turned to position ÔIIÕ, the initialization of the system is carried out, which
takes a few seconds. When complete, the system is ready to accept voice commands. If the voice
button is pressed before initialization is complete, the message center display will show ÔVOICE NOT
READYÕ.
Audible Feedback, Confirmation & Prompts
For most voice commands, audible feedback of the command, as understood by the system, is available.
Audible feedback may be turned on or off by giving the VOICE FEEDBACK command.
For the phone dial commands, confirmation of the number, before it is dialed, may be turned on or off
by giving the PHONE FEEDBACK command. During some commands for voice training, the user is
prompted by the system to give the next item of information.
For specific operation of all the controls, refer to the OwnerÕs Voice Activation Handbook.
Voice Training
The Voice Activation System is able to interpret most English speakers without difficulty. If, however, it is
found that commands are sometimes not being recognized, the voice training procedure can be carried
out.
Voice Memories
The system has two memories (A and B) for storing the trained voices. The Voice Memory Directory
command provides an indication of the availability of the two voice memories (Full or Available).
Giving Commands after Training
After Voice training the system will automatically recognize a speaker whose voice is held in voice
memory. The system can still be used by other speakers with no loss of response.
Error Messages
In addition to the voice command prompts given by the system, the following error messages may be
encountered. The messages are shown on the message center with voice confirmation (error tone or
voice playback).
