Key transmitter battery renewal
When the battery needs renewal there will be a significant
decrease in the effective range of the key transmitter. To renew
the battery, follow the procedure below:
• Insert a small, flat-blade, screwdriver at an angle of about 45 degrees, into the slot on th e back of the key transmitter
as shown ( A). Apply light pressure to the screwdriver and
lever the screwdriver forward to separate the two halves of
the key transmitter. Finally, pu ll the transmitter from the key
body.
• Insert the screwdriver into th e slot between the transmitter
covers adjacent to the key stowage area as shown ( B).
Apply light pressure to the screwdriver and lever the
screwdriver downward to separate the covers.
• Unscrew and remove the small screw ( C) and remove the
printed circuit board, taking care not to touch the battery
terminals. Remove the battery and dispose of it safely.
• Fit a new battery cell, type CR2032 (available from your
Jaguar Retailer), with the si de marked with the positive
symbol (+) downwards in the battery receptacle.
Avoid touching the new battery as moisture/oil from the
fingers can reduce the life of the battery and corrode the
contacts.
• Replace the printed circuit board making sure to engage the board under the securing tabs (D ), and secure with the
screw.
• Refit the cover and click into place with thumb pressure.
• Slide the transmitter back onto the key body until it clicks
into place.

3 - 16 Before Driving
Air bag fault warning light
The air bag warning light in the driver’s
instrument cluster will be lit for
approximately six seconds when the
ignition is turned on.
If the light remains on or flashes,
it indicates a fault within the air bag
electrical circuits. Report the fault to a
Jaguar Retailer immediately. It is safe to
drive the vehicle; however, in an accident
the air bags may not operate.
Air bag warning ligh t information is
shown on page 4 - 8. Air bag disposal
!WARNING:
Do not attempt to service, repair or
modify the air bag sy stem or its fuses.
All work on the air bag system,
including renewal after deployment
and renewal at the end of its service
life, must be carried out by an
authorised Jaguar Retailer.
In the event of the vehicle being
dismantled, air bag module removal and
disposal MUST be made by a qualified
person. Instructions can be obtained
from an authorised Jaguar Retailer. Front protection
With a front impact of sufficient force,
the restraints system will trigger the front
air bag(s) and seat belt pretensioners,
which immediately tighten the seat belts.
For front occupants, the seat belt then
slackens with increasing chest load,
allowing the head and chest to more
gradually come into contact with the
inflated air bag. The air bag absorbs the
remaining energy of the impact and then
deflates rapidly via vent holes.
Front air bags are designed to inflate in
frontal and near fr
ontal collisions,
not low speed impacts, roll-over, side-
impact or rear-impact.

3 - 20 Before Driving
Rear Impact Protection
Both front seats have active, energy
absorbent backrests which, with correctly
positioned headrests, reduce the risk of
neck and spinal injury (‘whiplash’) in the
event of a rear impact.
When activated, the seat backrests
automatically move back and recline,
altering the occupants’ posture and
reducing relative motion between the
body and head.
The degree of backrest movement in a
rear collision depends on the angle,
speed and nature of the colliding vehicle.
After activation, the w hiplash protection
mechanism will not work again and the
seat must be serviced by a Jaguar Retailer
to restore the protective function.
Note: The amount of backrest movement
depends on the severity of the impact and
for a minor collision there may be no
apparent change to the seat even where
the protective system has been activated.
After any rear collisio n, therefore, the seat
must always be inspected by an
authorised Retailer.
!WARNING:
1. For optimum protection, the driver and passenger should
sit in the centre of the seat with
the head as close as possible to the
head restraint.
2. Adjust the head re straint so that it
is just behind your head and never
behind your neck.
3. Do not wedge objects (e.g. luggage) between the front
seat backrest and the rear seat
cushion. 4. After a rear collision, the front
seats must be inspected by a
Jaguar Retailer even where there
is no apparent da mage or change
to the seat.
5. Do not attempt to service or tamper with the seat recliner
mechanism.

On the Road 4 - 7
Brake (RED)
Lights up when:
• The ignition is ON and the parkbrake is ON.
• There is a fault with the parkbrake.
• The brake fluid is low.
If the light is ON and there are no
associated messages it means that the
parkbrake is applied.
If the light flashes, th ere is a fault with the
parkbrake system and the parkbrake
cannot be applied.
If the light is ON and the message
‘PARKBRAKE ON’ is displayed, it means
that the parkbrake is applied but the
vehicle is moving. Release the parkbrake
or stop the vehicle when it is safe to do
so. If the light is ON and the message ‘LOW
BRAKE FLUID’ message with a RED
priority light is displayed on the message
centre, low brake fluid is indicated.
In this case, loss of braking in one,
or both, brake circuits may be imminent.
!WARNING:
If the message ‘LOW BRAKE FLUID’ is
displayed, DO NOT drive the vehicle
until the fault is rectified. Consult a
Jaguar Retailer immediately.
Anti-lock Braking
System (ABS) (AMBER)
If a fault has been detected in
the anti-lock brake
system (ABS) or the electric
parkbrake system, this light will
illuminate.
A warning message will appear with this
light to indicate either ABS fault or
parkbrake fault.
The brake system will continue to
function normally, but without ABS
braking.
Should the light come on or stay on after
the bulb check cycle, stop the vehicle at
the first opportunity, turn the engine OFF
and then restart.
If the ABS light comes on again,
the vehicle should be driven to a Jaguar
Retailer at the earliest opportunity.
!WARNING:
If the ABS and brake warning lights
are ON at the same time, DO NOT
drive the vehicle until the fault is
rectified. Consult a Jaguar Retailer
immediately.

On the Road 4 - 17
AIR SUSPENSION FAULT None None Drive the vehicle with caution and inform your nearest Jaguar Retailer to have the
fault rectified.
VEHICLE TOO LOW None None The air suspension system is too low. Start the engine and wait for the message to clear before driving the vehicle. If the message is displayed while you are driving,
restrict your speed until the message is cleared. If the message is persistently
shown, inform your Retailer.
DRIVER’S
(or PASSENGER’S) DOOR AJAR None Red The driver’s and/or one or more passenger doors are open. Check that all doors
are closed before driving.
TRUNK OPEN None Red Check that the luggage co mpartment lid is closed before driving.
HOOD OPEN None Red Check that the hood is closed before driving.
ABS FAULT ABS Amber ABS will not be available. The braki ng system will work but care must be used if
braking heavily.
STEERING COLUMN LOCKED None Amber The steering lock system has failed to unlock the steering column. The engine
cannot be started. Remove the key and re-insert it into th e ignition switch, then try
again to unlock the column by turning the steering wheel gently to the left and
right (only small movements will be possible).
TRANSMISSION FAULT None Amber It is likely that the driver will expe
rience a degradation of transmission operation
and possibly reduced ac celeration capability.

4-46 On the Road
Dynamic Stability
Control (DSC)
Unless it has been switched off, dynamic
stability control is operational whenever
the engine is running. If the system is
operating, the warning light in the
instrument cluster will flash.
The DSC system controls the anti-lock
braking system (ABS), traction control
and yaw control of the vehicle.Yaw control determines the vehicle’s
direction relative to
the driver’s inputs
(sideslip and under/ov ersteer). It applies
braking pressure to individual wheels if
excessive variation is detected.
This ensures that the vehicle follows the
driver’s intended direction of travel.
Traction control will intervene to reduce
wheel spin, by automatically reducing the
power output from the engine and
applying braking to individual wheels.
This improves acceleration, particularly
on surfaces with uneven friction,
for example, one wheel on ice the other
on tarmac.
ABS helps to prevent the road wheels
from locking and skidding during
emergency braking.
When the system is operating,
the warning light in the instrument
cluster will flash.
The dynamic stability control system can
be switched OFF by pressing the switch
on the centre console switchpack.
The warning light in the instrument
cluster will remain on and a message will
be shown to indicate that the system has
been switched OFF. If the switch is
pressed again the system will switch ON. Note:
If cruise control is engaged it will
automatically disengage if stability control
activates.
A system malfunction is indicated by the
message:
DSC NOT AVAILABLE
Warning light: Amber .
and the instrument cluster DSC warning
light will be lit.
It is safe to drive the vehicle but the
system may not activate under wheel spin
or slide conditions. Report the fault to a
Jaguar Retailer as soon as possible.
!WARNING:
1. The fact that the vehicle is fitted with Dynamic Stability Control
must never allow th e driver to be
tempted into taking risks which
could affect his/her safety or that
of other road users. In all cases it
remains the driver’s responsibility
to drive safely according to the
prevailing conditions.
2. It is recommended that when using snow chains, DSC should be
switched OFF.

On the Road 4 - 47
Anti-lock Braking
System (ABS)
This system helps to prevent the road
wheels from locking and skidding during
emergency braking, assisting the driver to
maintain full steering and directional
stability.
The factor controlling ultimate stopping
distance and cornering ability is tyre/road
adhesion.
!WARNING:
1. The fact that a vehicle is fitted with ABS must never allow the
driver to be tempted into taking
risks which could affect his/her
safety or that of other road users.
2. The addition of ABS cannot overcome the consequences of
trying to stop in too short a
distance, cornering at too high a
speed, or the risk of aquaplaning. 3. The driver should always take
road conditions into account.
A slippery road surface always
requires more braking distance
for a given speed, even with ABS.
A possible increase in stopping
distance compared to locked
wheels may occur during ABS
operation on slushy snow, gravel,
sand, or some heavily corrugated
or ridged warning sections of road
surfaces.
ABS optimises tyre/road adhesion under
maximum braking conditions though it
cannot provide increased cornering
ability. There is no need for special
braking techniques, such as ‘pumping’
the brakes, to achieve optimum braking
distances and control on poor or slippery
road surfaces. Tyres must be in good
condition to achieve maximum adhesion. During normal brakin
g the ABS will not
be activated. Howe ver, if the braking
force applied begins to exceed tyre/road
adhesion the ABS will automatically
activate, preventing the road wheels from
locking.
In these circumstances a pulsating effect
will be felt from the brake pedal
indicating that the sy stem is functioning.
The pulsating effect is due to small
fluctuations in pressure supplied to the
brakes by the system to maintain full
tyre/road adhesion.
Under severe braking on some road
surfaces tyre noise may be apparent even
though the wheels will at no time become
locked.
