4-62 On the Road
Towing a Trailer
Your Jaguar Retailer, and the main
motoring organisations can advise you on
towing, towing weight capacities and
about regulations that apply in other
countries.
The following are important points of
safety, stability and comfort upon which
further advice should be sought:
• Maximum braked towing weight is permissible, provided long periods of
uphill driving on gradients over 8%
are not undertaken.
• In high altitude mountainous regions, the thinner atmosphere can reduce
engine performance. Above 3280 feet
(1000 metres) the stipulated
maximum permitted gross train
weight must be reduced by 10% for
every 3280 feet (1000 metres) in
altitude.
• The kerbside weight of the vehicle can be found on page 8 - 4.
• When towing at the maximum permissible rear axle load keep within
legal towing speeds but in any case do
not exceed 62 mph (100 km/h). • Tyres must be inflated to the normal
(higher) pressures shown on the tyre
pressure label on the fuel filler flap.
• The recommended maximum tow-ball nose weight is shown
on page 8 - 5. Having a lower nose
weight or exceeding the maximum
nose weight limit may impair the
vehicle’s handling.
• When towing, the nose weight of the trailer and the tow-bar assembly must
be deducted from the permissible
maximum load, see page 8 - 5.
• Avoid heavy braking. As the overrun brake on the traile r is not connected
to the ABS, heavy trailer braking
could critically affect the stability of
the outfit as a whole.
• Ensure that the towing vehicle’s engine, transmission, suspension,
brakes and tyres are fully efficient and
regularly serviced. Similarly check the
wheels, tyres, brakes and wheel
bearings of the trailer. Caution:
1. When not in use, it is
recommended that the removable
tow-ball is either securely stowed
in the luggage compartment or,
preferably, not in the vehicle.
Do not leave it loose in the
vehicle.
2. It is essential that only a Jaguar tow-bar and Jaguar electrical tow-
bar kit are supplied and fitted by a
Jaguar Retailer. Contact your
Jaguar Retailer for details of
additional parts that are advised
to be fitted before towing. This is
particularly important with this
vehicle having air suspension.
If unapproved towing equipment
is used whilst towing, the air
suspension speed lowering
function will not be inhibited.
This may result in a change in
trailer weight distribution and
attitude.

6 - 4 Roadside Emergency
Trunk Underfloor Access
The space under the trunk floor houses
the spare wheel, battery, jack and rear
fuse box.
To raise the floor panel, press down the
rear of handle (A) then, holding the
handle at the front, swing the floor panel
upwards ( B). Hook the handle securely
over the top edge of the trunk
opening ( C).
Emergency Starting
This vehicle is fitted with automatic
transmission. In the event of a discharged
battery preventing a normal engine start,
the vehicle cannot be started by pushing
or towing. Either use jump leads
connected to a booster battery (e.g. on
another vehicle) or fit a fully charged
battery (see page 7 - 15).
Emergency Starting Using
Jump Leads
Both the booster and discharged battery
should be treated with great care when
using jump leads. Al ways use high quality
leads capable of carrying the starter
current of the vehicle to be started.
Before commencing, the following
precautions must be taken:
• When the battery of another vehicle is being used, ensure that the vehicles
do not touch. Alternatively, remove
the charged battery and place near to,
not on, the vehicle with the
discharged battery.
• Ensure that both vehicles have all electrical services OFF,
the parkbrakes applied and the
transmission in the ‘P’ (park) position.
• Where the jump leads are of a different colour, e.g. red and black,
use red for positive (+). This aids
identification and helps to avoid
crossing positive (+) to negative (–).
Take extra care to avoid crossing the
polarity when using cables of the
same colour.

Roadside Emergency 6 - 5
Caution:
1. If using a jump start vehicle, under no circumstances should the
vehicles come into contact with
each other. This could establish an
earth connection, which may
cause sparks and damage.
2. Do not run the engine of the jump start vehicle when boost starting a
Jaguar vehicle. If the jump start
vehicle’s engine is running and
the jump leads ar e disconnected,
damage to the Jaguar vehicle’s
electrical system will result.
3. The booster battery voltage must not exceed 12 volts.
The procedure must be followed exactly,
being careful not to cause sparks:
1. Unclip the battery positive (+) terminal cover.
2. Attach one end of the red jump lead to the positive (+) terminal of the
booster battery and the other end to
the positive (+) terminal of the
discharged battery. Make sure that a
good connection is made.
Caution: Do not connect the negative
jump lead directly to the negative (–)
terminal of the discharged vehicle. 3. Attach one end of the black jump lead
to the negative (–) terminal of the
booster battery and the other end to
the earth stud on the left-hand side of
the spare wheel well.
4. Start the engine.
5. When started, allow the engine to idle for five minutes before disconnecting
the cables.
6. Disconnect the black jump lead from the earth point and the booster battery
negative (–) terminal. 7. Disconnect the red jump lead from the
positive (+) terminals of both
batteries.
8. Refit the cover to the positive (+) terminal.
9. Close the trunk floor panel.
After starting the engine, it may be
necessary to reset th e electric parkbrake
as described on page 4 - 34. See also After
battery reconnection on page 7 - 16.

Roadside Emergency 6 - 9
Wheel Changing Procedure
1. Ensure that all passengers are in a safe place, clear of the vehicle.
2. Apply the parkbrake and select gear position ‘P’ (Park).
3. Ensure that the jack is placed on firm and level ground.
Note: When one rear wheel is lifted off
the ground the selection of gear position
‘P’ (Park) will not prev ent the vehicle from
moving and possibly slipping off the jack.
!WARNING:
1. Before attempting to lift the vehicle with the jack, chock the
wheel diagonally opposite to the
wheel being replaced to prevent
the vehicle from rolling when
jacked up. A wheel chock is
supplied with the jacking
equipment for this purpose.
2. Never work under the vehicle using only the jack as a support,
always use axle stands or suitable
supports under the jacking points. Observe the instructions printed on the
jack.
Use the jack only for lifting the vehicle
during wheel changing, and only use the
jack which is stored in the vehicle.
Do not start or run the engine while the
vehicle is only supported by a jack.
Removing the wheel
Before raising the vehicle slacken but do
not remove the wheel nuts.
There are four jacking points, two each
side of the vehicle on the underside of the
floor. These provide positive location for
the jack. To locate the jacking
point, feel along the
sill panel to the cut-away portion and
then fit the jack to the body, as shown,
not to the sill panel .
Caution: Ensure before raising the
vehicle that the jack is correctly
positioned to avoid any damage to
the vehicle sills or sill panels.
Use only the correct jacking points,
never use bumpers or any other part
of the body to lift the vehicle.

6 - 10 Roadside Emergency
!WARNING:
1. Do not attempt to lift the vehicle unless the jack head is fully
engaged in the jacking point.
2. Ensure that the parkbrake is applied.
Place the jack squarely beneath the
appropriate jacking point. Ensure that the
jack head is fully engaged. Carefully raise
the vehicle by turning the handle.
Stop jacking the vehicle when the tyre
just clears the ground. Minimum tyre lift
gives maximum vehicle stability.
Remove the wheel nuts and the wheel.
Centre badge
When changing the alloy road wheels,
transfer the centre badge to the
replacement wheel. Using the plastic
tipped end of the wheel nut wrench
handle from the inside of the wheel, push
the centre badge from its housing.
Push the centre badge into the
replacement wheel. Fitting the spare wheel
Fit the spare wheel and loosely secure
with the wheel nuts.
Using the wheel nut wrench, lightly
tighten the wheel nuts
alternately using
the sequence shown in the illustration.
Lower the jack and ti ghten the wheel nuts
alternately, DO NOT OVER TIGHTEN.
At the earliest opportunity have the
wheel nuts tightened with a torque
wrench to 92 lb.ft (125 Nm).
This torque must not be exceeded. Stowing the equipment
Stow the replaced road wheel in the
trunk.
Check that the locking ring is unscrewed
fully so that it is as close as possible to the
handle of the wheel retainer. This is to
ensure that the wheel retainer can be
fitted correctly.
Locate the wheel retainer into its mating
thread in the trunk floor and tighten it
fully, then tighten the locking ring
clockwise to secure the wheel.
Seepage6-8.
Stow the jacking equipment.
Close the trunk floor panel.
!WARNING:
When a temporary spare wheel is
fitted, drive with caution and replace
with the specified wheel and tyre as
soon as possible.

Roadside Emergency 6 - 11
Vehicle Recovery
The preferred vehicle recovery method is
by using a flat bed transporter or rear
suspended tow.
Caution:
1. If the vehicle has defective transmission, to prevent further
damage, it must be towed with
the rear wheels clear of the
ground.
2. Ensure that the recovery team do not tow with sling-type
equipment since damage to the
bodywork may result.
3. Do not tow the vehicle by suspending the front end.
Transporting
If the vehicle is being transported on a
trailer or flat bed transporter,
the parkbrake must be applied,
the wheels chocked and the gear selector
lever moved to position ‘N’ or ‘D’ but
NEVER to ‘P’.
The vehicle must be securely tied down
to the transporter or trailer, see next
page.

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.
