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.

Introduction
The automatic and manual transmission units are
described in the ÔS-TYPE Sports Sedan Powertrain
IntroductionÕ Technical Guide.
J-Gate
The J-gate assembly is mounted on the
transmission tunnel by four bolts and has a
similar operating mechanism to the XJ/XK Series
vehicles. The selector gate positions are, P-R-N-D
on one side of the ÔJÕ and manual gear positions
4-3-2 on the other side. Movement of the gear
selector lever up and down these positions is
transmitted mechanically to a cable assembly
which then rotates the digital range switch on the
side of the automatic transmission housing (see
ÔS-TYPE Powertrain IntroductionÕ Technical
Guide). Movement across the gate between D and
4 operates an electrical switch (without cable
movement).
In the P position with the ignition off, the gear
selector lever is locked by a solenoid plunger
which inhibits a lock plate fixed to the selector
mechanism. When the ignition is switched on,pressing the brake pedal energises the solenoid
and releases the lock plate, allowing the selector
lever to be moved from the P position.
For NAS markets only, the J-gate slider actuator is
linked to the ignition switch barrel to provide a
mechanical interlock. The interlock lever and
cable are driven by the J-gate slider to operate a
locking plunger in the ignition barrel. If the gear
selector lever is in any position other than P, the
ignition key cannot be removed. Note when
servicing, that the interlock cable adjustment is
critical and the JTIS service instructions must be
followed. Where the interlock function is not
fitted, the interlock lever is retained without the
operating cable.

Driveline
Introduction
The driveline is a standard type with the engine
position at the front and driven rear axle. This will
be the first time that Jaguar has used in-plant
driveline balancing to improve noise, vibration
and handling. The driveline is finely balanced at
the rear driveshaft joint. The centre bearing is
laser aligned during initial factory build.
The alloy rear engine mountings have two
variants, one for automatic transmission and one
for manual transmission. They are both
serviceable items. The V6 auto is the same as the
V8 but rotated in plan by 180 degrees. The rubber
mountings are carry over concept from the
current XJ and XK Series vehicles but are not
D.307.322
DRIVELINE ARRANGEMENTinterchangeable with them. Both automatic
transmission rubber mountings are common but
with a softer unique mount for the manual V6
transmission.
In service if they are replaced, ensure that there
are buffer gaps and that they are approximately
equal. Neither will be contaminated by lubricant
or automatic transmission fluid.
Driveshaft
The S-TYPE has a two-piece welded steel tube
driveshaft with a splined centre slip joint and
locking collar, the whole being aligned with the
body centreline. The driveshaft has rubber flex
couplings and a rubber, body-mounted, centre
bearing. For safety, the front tube is collapsible.
JAGUARS-TYPEChassis
54The centre joint is a conventional hookes joint
with staked lugs and the rubber flex couplings
have spigoted sleeves to the transmission and rear
axle final drive unit (three bolt fixings)
All driveshafts are balanced. If undercoating the
vehicle, protect the driveshaft, universal joints
and the axleshafts to prevent overspray of the
undercoating material.
Driveshaft weight is:
¥ V6 auto 12.7 kg
¥ V8 auto 13.4 kg
¥ V6 manual 14.1 kg
Serviceable parts are the centre bearing, flex
coupling, rubber boot, alignment bearing and
fasteners. Lubrication of the driveshaft
components is unnecessary. The universal joint is
equipped with nylon thrust washers, located at
the base of the bearing cup.
Balancing of the driveshaft is achieved using a
PDU with the new vibration analyser. This gives
details of where the shaft is out of balance and by
how much and where to place the balance nuts.
Final Drive (differential)
The final drive, differential, has a steel case and
rear cover, no drain plug and has a sealed for life
lubricant. Differential weight is 27 kilograms and
oil capacity 1.5 litres of synthetic oil (M2C192A).
The hypoid gearset is mounted in taper roller
bearings. It has a two point differential assembly
retained by bearing straps. The central pinion is
on the body centreline. Pinion and output oil
seals, the companion flange and nut and the
needle roller output bearing are the only
serviceable items.
Final drive ratios are:
3.31:1 (V6 and V8 auto)
2.87:1 (V6 manual)
Differential Mountings
The crossbeam forms the mounting points for the
three differential mounting bushes. All three
bushes are conventional rubber bushes, common
to all S-TYPE vehicles and are serviceable items.
They control the driveline and isolate differential
noise and vibration. Avoid disturbing the subframe
mounts when servicing differential bushes. The
front differential bush is a two-part bush and the
RH and LH rear bushes are handed and colour
coded to differentiate them
Half-shafts
Half-shafts are unequal lengths and are therefore
handed, left and right. Constant velocity joints are
fitted to both ends, the outer is fixed and the
inner is sliding. They are sealed for life and
retained in the differential side gear with a spring
clip.
Weights are approximately
V6 size - 100 8.89kg (LH) 8.76kg (RH)
V8 size - 104 9.43kg (LH) 9.3kg (RH)
Serviceable parts are:
¥ the pinion and output oil seals
¥ companion flange and nut
¥ output bearing (needle roller)
Note: It is possible that the replacement or repair
of gears, bearings or shafts may be introduced at a
later date.

BRAKE BOOSTER Brake Booster
The brake booster is a Lucas unit mounted on the
engine bay bulkhead with a 25.4mm diameter
master cylinder and integral brake fluid reservoir.
NOTE: The reservoir is also a combined
brake/clutch reservoir for manual transmission
vehicles.
Twin vacuum boosters of 8 inch and 9 inch sizes
are fitted.
The DSC booster is different having integral
pressure transducers and solenoids with air
control valves for the booster. The transducers are
located on the brake master cylinder and are used
for pressure feedback, brake application and fail
safe operation. The booster is used to supply
brake pressure without driver input.
ABS operation is no different to current Jaguar
vehicles.
Parking Brake
The parking brake lever is mounted on the RH
side of the centre console for all models, with
conventional button operation as current XJ
sedan. It is a self-adjusting system operating on
the rear brake callipers. All models have a leather
grip.

FRONT STEERING ARM requires a Service tool to assist removal. Low-
pressure hose connections are made using
Constant Tension (CT) clamps. Pinion hydraulic
connections are orientated with the bottom
connector low pressure with the longer nut, as
current vehicles.
The PAS fluid is for PAS only; it is not to be used
for transmissions. After manual filling, the system
must be bled using a vacuum pump to remove all
the air from the system to prevent system noises.
Fluid level is checked through a sight window on
the reservoir.
Components replaceable are complete pump,
steering rack, reservoir or hose assembly.
A non-serviceable 10-micron filter is located
within the reservoir to maintain fluid cleanliness
throughout the life of the vehicle. It is essential as
with all Jaguars that the system does not become
contaminated. Cap all ports on disassembly to
prevent contamination ingress. As with current
vehicles, the fluid and reservoir must be renewed
if any major component is replaced i.e. Rack,
pump or cooler.
The road wheels should be set straight ahead and
the steering wheel locked (using service tool
F7LC-3F732-BF) when removal and assembly of
the steering gear or intermediate shaft is required.
This is necessary to prevent damage to the air bag
clock spring within the steering upper column
assembly. The intermediate shaft can only be
assembled to its mating components in one
location. Steering wheel alignment can only be
achieved by adjustment at the tie-rods. A
dimensional check of the steering rack position
may be necessary to verify rack centre.
Steering Column
The steering column assembly is completely new
and uses no parts from previous Jaguar
assemblies:
¥ Construction of the upper column assembly is
based on the use of aluminium extrusions and
castings.
¥ A two shaft lower column assembly is used.
¥ The electronically controlled steering lock, the
steering column lock module (SCLM), is a
physically separate component from the
ignition switch which is fascia mounted.
¥ The dynamic stability control (DSC) steering
wheel position sensor is fitted to the upper
column assembly.
Steering Wheel
The steering wheel consists of a magnesium
armature with a central steel insert. The steering
column and wheel insert are splined with a flat so
that the wheel can only be fitted in one position.
Any misalignment of the steering wheel is
corrected by adjusting the tie rods. The splined
fitting also has a locking taper which requires the
use of a 2 legged puller to remove the wheel.
The steering wheel incorporates the the airbag
module, horn mechanism and the optional cruise
control and audio/phone switches.
JAGUARS-TYPEElectrical/Electronic
103 Note: If the switches are held for longer than six
seconds, e.g. when attempting to overcome frozen
or jammed windows, the window drive will be
switched off for a few seconds to protect the
window drive motors.
Memory Setting (where fitted)
The position of the driverÕs seat, steering column
and exterior rear view mirrors can be memorized
and recalled. Two different driving position
profiles can be entered In the memory. The
switches for seat, mirror, steering column
adjustment and memory setting can be operated
with or without the key being in the ignition.
To store a driving position in the memory:
1. Adjust the seat, steering column an exterior
rear view mirrors to the desired position.
2. Push the memory button and the light in the
switch will illuminate
3. Within five seconds, push button Ô1Õ orÕ2Õ to
memorize the configuration. The memory
button light will go out and a chime will
indicate that the setting procedure is
complete. Additionally, if the ignition is on,
the message center will display a message
that the settings have been saved.
To recall a memorized position, the gear selector
lever must be in ÔPÕ or ÔNÕ on automatic
transmission vehicles and the park brake must be
applied on manual transmission vehicles. Press
and release the appropriate memory button (Ô1Õ or
Ô2Õ). The seat, steering column and door mirrors
will move automatically to the memorized
position.
The key ring transmitter can also be set to
memorize the position of the driverÕs seat,
steering column and exterior rear view mirrors.
Memory Recall Using a Key-ring Transmitter
The key-ring transmitter will recall a memory
position when the unlock button is pressed when
set as follows:
Adjust the seat, steering column and exterior rear
view mirrors to the desired position.
Press ÔmemoryÕ button.
Within five seconds, press any button on the key-
ring transmitter.
Press button Ô1Õ or Ô2Õ.
Repeat for the other transmitter, pressing the
remaining memory button.
To cancel key-ring transmitter memory recall:
