6 - 12 Roadside Emergency
Transporter tie-down procedure
!WARNING:
Avoid body contact with a hot
exhaust pipe when securing the
vehicle to the transporter.
IMPORTANT – Use straps over the
wheels/tyres only, to secure the vehicle to
the transporter.
Caution: Do not use the tie-down
brackets on the vehicle rear
underbody; these are for Jaguar
factory use only. In time, with the
engine switched off, the vehicle body
will drop due to settling of the air
suspension system and cause the tie-
down chains/straps to become slack if
connected to these brackets.
The towing eye is not designed for
securing the vehicle during
transportation. Vehicle failure
The removable towing eye is primarily for
emergency use when towing for SHORT
DISTANCES, e.g. removing the vehicle if it
is causing an obstruct
ion or for winching
the vehicle onto a re covery transporter.
To prevent damage to the automatic
transmission whilst the vehicle is being
towed with the rear wheels on the
ground, towing distance must be
restricted to 0.5 miles (0.8 kilometres).
Towing speed must not exceed 30 mph
(48 km/h).
Always obey towing regulations.
In certain countries the registration
number of the towing vehicle and an
‘ON TOW’ sign or warning triangle must
be displayed in a prominent position at
the rear of the vehicle being towed. When being towed, the gear selector
lever must be in neutral (position ‘N’)
with the ignition key turned to
position ‘II’ to release the steering lock
and render the indicators, horn and
brake lights operational.
!WARNING:
When the engine is not running the
steering and brakes will no longer be
power-assisted.
Therefore, be prepared for relatively
heavy steering and the need for
greatly increased brake pedal
pressure.

Fuse Box Locations
There are three separate fuse boxes fitted
to the vehicle, each one containing fuses
protecting a different group of circuits.
Engine compartment fuse box
The fuse box is located in the engine
compartment on the right-hand side
adjacent to the windscreen wash
reservoir.
Remove the fuse box lid by pressing the
spring catch and lifting.
When refitting, press the fuse box lid in
the area of the retaining lugs until the lid
engages. Cabin fuse box
The cabin fuse box is located behind the
right-hand side trim panel in the footwell.
To access the fuse box, pull out the
bottom of the trim panel (arrowed), slide
the panel down slightly and remove.
Trunk fuse box
A fuse box is located in the trunk,
situated behind the battery.
Open the trunk floor panel to gain access
to the fuse box.
Remove the fuse box lid by pulling the
retaining clips and pulling the lid
upwards.
Reposition the lid and press down until
the retaining clips engage.
Replace the floor panel.

Regular Checks
In the interests of safety and reliability,
it is advisable to carry out the following
checks at the recommended intervals,
and always before starting on a long
journey.
Daily
Check that there is sufficient fuel for the
journey intended, particularly at night
and before joining motorways.
Weekly
Tyres– Check the tyres, including the
spare, for condition and pressure.
Tyre pressures are explained on page 8 - 8
and shown on a label inside the fuel filler
flap.
Lights – Check that all exterior lights and
direction indicators function correctly
and that the lenses are clean.
Engine oil – With the vehicle standing
on level ground, check the oil level and
top up if necessary with oil of the correct
grade.
Engine coolant – With the engine cold,
check the level of the coolant in the
coolant reservoir header tank. Any loss of
fluid must be checked by a Jaguar
Retailer. Brake fluid
– Check the level of the fluid
in the brake fluid reservoir. Top up if
necessary with new, unused Jaguar
approved brake fluid.
The reservoir is initially nearly full,
but the level will drop as the brake pads
wear. If the level appears unusually low,
location of the fluid leakage must be
checked by a Jaguar Retailer.
Power steering fluid – With the engine
cold, check the level of the fluid in the
power steering fluid reservoir. Top up if
necessary with fluid of the correct
specification. Any loss of fluid should be
checked by a Jaguar Retailer.
Windscreen washer fluid – Top up
with windscreen washer fluid and clean
soft water. Check the operation of the
washers. It is recommended that you
use Jaguar Windscreen Washer Fluid to
keep the glass clean and also to prevent
the fluid from freezing during cold
weather.
Monthly
Wiper blades – Check the quality of the
wipe. If smearing or juddering is evident,
clean the windscreen and wiper blades.
Used Engine Oil
!WARNING:
Prolonged and repeated contact may
cause serious skin disorders,
including dermatitis and cancer.
Always use a hand cream to protect the
skin from oil contamination.
Avoid contact with the skin as far as
possible and wash thoroughly after any
contact. Keep oils out of reach of
children.
PROTECT THE ENVIRONMENT: It is
illegal to pollute drai ns, watercourses and
soil. Use authorised waste collection
facilities, including civic amenity sites and
garages providing fa cilities for the
disposal of used oi l, oil filters and
batteries. If in doubt, contact your Local
Authority for advice on disposal.

Hood Release
!WARNING:
Take care to keep away from rotating components if the
engine is running when you open the hood.
Release the hood lock by pullin g the lever below the fascia on
the left-hand side of the vehicle.
Lift the hood slightly and push the safety catch, located under
the centre of the front edge of th e hood. The gas filled struts will
assist raising the hood, and retain it in the fully open position.
!WARNING:
Before closing the hood ensure that no-one is obstructing
the closing area and that hands and clothes are clear.
Remove tools, cleaning cloths, etc., from the engine
compartment.
Close the hood to within a distance of 12 to 14 inches
(30 to 35 cm) of the fully closed position, then let go to allow
the hood to shut. Check by pulling the hood that both the right-
hand and left-hand latches are engaged.
