Security Features
The security system has been designed
for:
• Prevention of theft of the vehicle.
• Prevention of theft of items from the vehicle.
• Personal security.
The security system is integrated with the
vehicle electronics and engine
management systems making it far more
difficult for a thief to penetrate and steal
the vehicle.
Panic Alarm (if enabled)
When in or near the vehicle, the alarm
can be set off to dete r a possible offender.
For this feature to operate, the key must
not be in the ignition switch.
Pressing the headlamp convenience/panic
button on the key transmitter three times
within three seconds will activate the
‘Panic Alarm’.
The alarm is stopped by:
• Putting the key into the ignition switch and turning to position ‘II’.
Note:
1. The key transmitter cannot be used to cancel the Panic alarm. This prevents
unauthorised cancellation in an
emergency.
2. The panic alarm is normally enabled. If required, this feature can be
disabled or enabled by a Jaguar
Retailer.
3. The vehicle locking status will not change when the panic alarm is
activated.
Passive Arming (Retailer
Option)
Passive arming wi ll not lock the
doors, it only arms the security alarm
system.
Passive arming, if enabled by a Jaguar
Retailer, will automatically arm the
vehicle alarm system 30 seconds after the
last protected entry (door, luggage
compartment) is closed following the key
being removed from th e ignition switch.
When passive arming occurs the direction
indicators will flash once and a single
tone will be heard (if enabled). The red
security light on the fascia will start to
flash and will continue for as long as the
alarm is armed.
Opening the drivers door causes a
warning sound which continues for
15 seconds before the system goes into
the full alarm state. If any other door is
opened before the drivers door,
the system goes into the full alarm state
immediately.
When the system is pa ssively armed and a
key is used to open the trunk, a seven
second warning audible ticking will
sound before the full alarm is activated.

unplug the device during the ‘cycling’
process to prevent possible motor
failure.
It is recommended that for best results,
fit a new battery to the hand-held
transmitter of the garage door opener
(or other device) before programming.
If your garage door opener receiver
(located in the garage) is equipped with
an antenna, ensure that the antenna is
hanging straight down.

begin to flash (this will take
approximately 20 seconds).
All memories in the garage door opener
have now been cleared.
