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.

Engine Compartment
The engine compartment layout is common for both V6 and V8 engines. The front power distribution
box (fusebox) is located in the engine compartment.

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.

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

compartment and a transfer module in the LH
compartment with external cross-over pipes for
fuel transfer between the compartments. Both
module assemblies have integral top plates for
external pipework and electrical connectors.
These are secured in the tank using screw on
plastic closure rings. The closure rings are
accessible from inside the vehicle via two access
holes in the floor panel below the rear seat. Due
to the confined working space and the possibilityof fuel spillage within the vehicle, it is advisable to
remove the tank completely before attempting to
remove the internal assemblies.

Fuel Flow
The variable speed fuel pump is contained in a
fuel reservoir in the RH module assembly. Fuel is
pumped from the reservoir through an external
cross-over pipe to the LH compartment where it
flows via a T junction to the parallel pressure
relief valve and then out to the engine fuel rail.
The reservoir is maintained by fuel supplied by jet
pumps in the LH and RH compartments.
Pressurised fuel from the variable speed pump is
forced through the small jet nozzles (diameter
0.5mm) creating a suction which draws fuel up
from the tank. From the LH tank, this fuel is
pumped through an external cross-over pipe and
then into the reservoir. In the RH tank, the jet
pump is located in the base of the reservoir.
The parallel pressure relief valve assembly
contains two spring loaded valves which operate
in opposite directions, a fuel rail feed valve whichopens at approximately 2 psi during normal
operation and a second valve which opens at
approximately 45-70 psi to relieve excessive rail
pressure.
The main functions of the valves are:
¥ To help engine starting by retaining fuel in the
supply lines and rail.
¥ To limit rail pressure due to temporary vapour
increase during hot soak conditions
(temperature and thus pressure drop after
approximately 20 minutes).
¥ To limit rail pressure caused by sudden load
changes such as a full to closed throttle
transition.
¥ To prevent siphoning from the tank in the
event of the fuel line being severed with the
pump inactive.
Each side of the tank has an independently
