Evaporative Emissions System
The function and operation of the on-board
refueling vapor recovery (ORVR) evaporative
emissions system are similar to the system fitted
to the XJ and XK Series vehicles in NAS markets
but use different components. For the S-TYPE the
system is fitted as standard for all markets.
Fuel Tank Components
To meet ORVR evaporative emission
requirements, the tank and associated
components are designed to minimise vapour
losses. During re-fuelling, the narrowed fuel filler
tube below the nozzle region provides a liquidseal against the escape of vapour and a check
valve in the tank inlet pipe opens to incoming fuel
only to prevent splashback. As the tank fills,
vapour escapes through the open float level vent
valve, at the top of the tank, and passes through
the adsorption canisters to atmosphere. When the
rising fuel level closes the float valve, the resulting
back pressure causes refuelling cut-off. While the
float valve is closed, any further rise in vapour
pressure is relieved by the grade vent valve which
connects to the canisters via the outlet of the float
valve. At less than full tank level, the float valve is
always open, providing an unrestricted vapour
outlet to the canisters.
If the tank is over filled (eg a fault in the delivery
system) an integral pressure relief valve in the float
valve assembly opens to provide a direct vent to
atmosphere.
The float level vent valve/pressure relief valve
assembly and the grade valve are welded to the
tank top and are non-serviceable. Note that both
valve assemblies incorporate roll-over protection.
The fuel filler cap uses a 1/8 turn action and is
tethered to the body. The filler cap assembly
incorporates both pressure relief and vacuum
relief valves (the latter is a new feature to Jaguar).

Fuses and Relays
Fuses
Fuse failure is identified by an inoperative circuit.
Two types of fuses are fitted in the fuseboxes, a
mini-type and a cartridge-type.
A special tool for removing and replacing the
mini-fuse is provided in the passenger
compartment fusebox, together with spare fuses.
If a spare fuse is used, replace it with a Jaguar
approved fuse of the same amperage rating.
Checking and Renewing a Blown Fuse
Make sure the new fuse is the correct rating
(amperage). Fuses are colour coded according to
the amperage and the rating is also marked on
each fuse.
WARNING:
Do not fit a fuse of a different amperage from
that removed. The electrical circuits may
become overloaded with the subsequent
possibility of a fire.
No attempt should be made to repair a fuse
that has blown. This may cause a fire hazard
or serious damage elsewhere in the
electrical circuit.
Fuse Boxes
There are three separate fuse boxes fitted to the
vehicle, each one containing fuses protecting a
different group of circuits.
They are located in:
¥ The engine compartment
(front power distribution box/fusebox)
¥ The passenger compartment
(primary junction box/fusebox)
¥ The luggage compartment
(rear power distribution box/fusebox)
Engine Compartment Fusebox
The fusebox is located in the engine compartment
on the RH side adjacent to the windshield wash
reservoir.
Caution:
When a fusebox lid is removed, take care to
protect the box from moisture, and refit the lid at
the earliest opportunity.
Remove the fusebox lid by pressing the retaining
lugs and lifting.
When refitting, press the fusebox lid in the area of
the retaining lugs until the lid engages.

The driver warning chime provides the driver with
an audible warning for the ignition on, key in
ignition, all doors open and the headlamps on,
hood open, trunk open, lamps on and safety belt
not engaged. A chime will sound every one
second when a fault in the air bag circuit is
detected.
The driver is also provided with a visual message
or warning displayed in the information message
center.
