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:
• Insert a small, flat-blade, screwdriver

at an angle of about 45 degrees, into
the slot on the back of the key
transmitter as shown (1). Apply light
pressure to the screwdriver and lever
the screwdriver forward to separate
the two halves of the key transmitter.
Finally, pull the transmitter from the
key body.

• Insert the screwdriver into the slot

between the transmitter covers
adjacent to the key stowage area as
shown (2). Apply light pressure to the
screwdriver and lever the screwdriver
downward to separate the covers.

• Unscrew and remove the small screw

(3) 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 Dealer),
with the side 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 (4), 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.

Care of key transmitters

The key transmitters must be treated with
care. Do not expose to extremes of heat,
dust, humidity or fluids. Do not leave the
transmitter exposed to direct sunlight.
The battery is the only serviceable part.

Caution: Should a key transmitter be
lost, a new one can be obtained and
programmed to the vehicle by a Jaguar
Dealer, who will ask for proof of vehicle
ownership. It is advisable to notify a
Jaguar Dealer as soon as a key
transmitter is lost or stolen and have
the remaining key transmitter(s)
reprogrammed. This will then prevent
the lost or stolen key transmitter from
being used to disarm and unlock the
vehicle.

Note: Jaguar Dealers keep a log of all
enquiries for replacement keys and notify
Jaguar Cars Limited of any such requests.

Door Locks

LOCK THE VEHICLE AND SET
THE ALARM

All doors can be centrally locked and
unlocked remotely, using the key
transmitter buttons.

Only the driver’s door is equipped with an
external key lock, which activates the
central locking, double-locking (when
enabled), two-stage unlocking (when
enabled) and central unlocking (when
enabled).
• Ensure windows and sunroof (if fitted)

are fully closed.

• Press the lock button on the key

transmitter, or;

• Put the key in the driver’s door lock,

turn the key towards the rear of the
vehicle and release.

The direction indicators will flash once,
and the security light (located on the top
surface of the facia) will start flashing.
After 20 seconds, the alarm will be set.

If a door, the hood or the luggage
compartment are open and an attempt is
made to lock the vehicle, the direction
indicators will flash five times (if enabled)
and/or an audible warning will sound
twice as a warning that the vehicle is not
secure.

Note: The security system will not arm if a
key is in the ignition switch. If a key is used
in the driver’s door key barrel and turned
towards the front of the vehicle and
released when an aperture is ajar, (2 error
tones (if enabled), or five flashes of the
direction indicators (if enabled) will be
emitted). The security system will arm, but
will not monitor the aperture that is ajar
until it has been fully closed.

Drive-away door locking

With the ignition key at position II and all
the doors closed, all doors will lock when
the gear selector is moved from position P
(Park) or N (Neutral). The gear selector
has to be moved from P or N, and into a
different gear, for longer than one second.

If the vehicle is stopped and a door is
opened and subsequently closed, the
doors will lock again when the gear
selector is moved from position P or N,
and into a different gear.

If the vehicle is stopped and a door is
opened and subsequently closed, but the
gear selector is not moved from position
P or N, or the current gear position, the
doors will remain unlocked.

All vehicles have the drive-away door
locking feature installed during
manufacture, except Japan.

This feature can be disabled, or
reinstated, by a Jaguar Dealer, if required.
