LUGGAGE COMPARTMENT
UNDERFLOOR ACCESS

The space under the luggage
compartment floor houses the spare
wheel, battery, jack and rear fuse box.

To raise the floor panel, press down the
rear of the handle then, holding the handle
at the front, swing the floor panel
upwards. Hook the handle over the top
edge of the luggage compartment
opening.

Be prepared for a flat tire. Know where
equipment is stowed and read the wheel
changing and jacking instructions
carefully. Keep the jack screw threads
clean and greased to ensure it is always
ready for an emergency.

Park off the road, clear of all traffic and on
as level, solid ground as possible. Switch
on hazard warning lamps and, where
legally required, display the warning
triangle.

Caution: Ultra high performance tires.

This vehicle is equipped with Ultra High
Performance (UHP) tire and wheel
combinations designed to provide
maximum dry road performance with
consideration for hydroplaning
resistance. These low profile high
speed rated tires may be more
susceptible to damage from road
hazards. UHP tires have performance
enhancing soft rubber tread
compounds, which when driven
aggressively experience rapid tread
wear and shorter life than less
performance oriented tires.

These tires are not recommended for
driving on snow or ice, and should be
replaced with winter tires when
weather conditions dictate.

Tires with all season and M + S icon
have a level of winter performance and
need not be replaced.

!

WARNING:

It can be dangerous to change a wheel
when the vehicle is on a slope or soft,
uneven ground.

The locking wheel nut comprises two
grooved parts, front and rear, which must
be turned together to allow the nut to be
fitted or removed.

To remove the nut, the front and rear
grooves must be aligned. Locate the key
socket in the grooves and push it fully
over both parts of the nut. Fit the wheel
nut wrench over the key socket and
loosen the locking wheel nut (turn
counter-clockwise).

Attempting to remove the nut without the
correct key socket (such as attempted
theft) or with the socket not located over
the rear part of the nut, will cause the front
part only (see item 1) to turn.

If this has happened, rotate the front part
with the key socket until the grooves are
re-aligned and then push the socket fully
over the nut.

Should a new key socket be required,
contact your Jaguar Dealer. Proof of
vehicle ownership will be required.
