GENERAL INFORMATION

When the vehicle is unoccupied or
unattended, you are advised to do the
following:
• Apply the Electric Parking Brake and

move the gear selector to the Park P
position.

• Do not leave children or pets in the

vehicle unattended.

• Do not leave luggage or valuables on

display.

• Remove all keys, including remote

transmitters, from the vehicle prior to
locking the doors, even when the
vehicle is in your garage.

• Close all windows, luggage

compartment and glove
compartment, and lock all the doors.

• Park the vehicle where it can be seen.

At night, park in a well-lit area.

• It is important to keep your keys in

safe places at all times. Leaving them
in conspicuous places is an invitation
for a thief to steal them and,
consequently, your vehicle or
belongings. Keep them as secure as
you would your wallet or purse, both
at home and away.

IMMOBILISATION SYSTEM

This vehicle is fitted with an
immobilisation system. The system
prevents the vehicle being driven away by
unauthorised persons.

Programmable key

An electronic device is fitted in the head of
each key which is programmed to the
vehicle electronic systems.

When a programmed key is inserted into
the ignition switch it is recognised and
accepted by the vehicle’s electronic
systems.

The engine cannot be started with a key
that is not programmed to the vehicle
electronic systems.

Immobilisation system status light

The immobilisation system status is
shown by a Light Emitting Diode (LED),
which is located on the top surface of the
facia panel (1).

If an ignition key is put into the ignition
switch and turned to position II, and the
LED remains flashing after three seconds,
it is possible that the engine will not start.

Should this occur, please contact a
Jaguar Dealer, who will investigate the
cause of the flashing LED.
