Liftgate release switch
For most markets excluding North America and Japan, the remote central locking system incorporates a double locking facility for optimum
security. All locks use the Tibbe key system, using 6 elements and 4 cuts. The keys include 'in-key' transponders which are programmed to
the vehicle engine immobilization system by using the Jaguar approved diagnostic system.
The central locking system employs single key access to the driver door, ignition switch and steering column lock.
When the vehicle is not locked, each door latch can be externally released by the corresponding exterior door handle which is operated by a
single rod. When unlocked, or central locked, the door latches can also be released by the interior door handles, each of which are operated
by a single cable. Operation of the front door interior handles will also unlock the rear doors. Use of the key in the driver door lock cylinder
operates the lock by a short rod to provide locking of the door latch. This in turn locks all other doors and the luggage compartment through
the central locking system. These locking functions can also be achieved by use of the integrated key remote entry transmitter.
For most markets, vehicles with 2.0L, 2.5L and 3.0L engines have a 'drive-away door locking' feature which automatically central locks all
doors and the luggage compartment when the vehicle exceeds 7 km/h (4 mile/h).
Key operation
To central unlock or lock the vehicle, the key is inserted in the driver door lock cylinder, turned towards the front or rear of the vehicle
respectively, and released. Holding the key in the lock position for 1.5 seconds will close all windows. Releasing the key stops all
operations. Central locking of the vehicle locks all doors and the luggage compartment and sets the alarm system. In addition to all of the
above functions, double locking prevents the doors opening from the interior. To 'double lock' the vehicle, the key is inserted in the driver
door lock cylinder and turned to the unlock (forward) position, then within three seconds, turned to the lock (rearward) position and
released. The same procedure is required to unlock a 'double locked' vehicle as with a central locked vehicle. The key is inserted in the
driver door lock cylinder and turned to the unlock (forward) position. This function can also be activated using the remote transmitter.
If an attempt is made to lock the vehicle from either front doors through the driver or passenger interior door handles, when a door, hood or
luggage compartment is ajar, will result in all doors being locked and then unlocked. If an attempt is made to lock the vehicle from either
rear doors through the interior door handles, or when the hood, a door or the luggage compartment is ajar or open, will result in only that
specific rear door to lock.
The fuel filler flap release lever is used to allow the driver to release the fuel filler flap from inside the vehicle. This function can be used at
all times.
Keyless Entry
The integrated key remote transmitter operates the following functions:
unlocking the driver door
unlocking/locking all doors
releasing the luggage compartment lid
activate/deactivate the double locking
arms/disarms the anti-theft alarm system, interior scanning system and the inclination sensor (if equipped)
activates global closing
deactivates a triggered alarm
headlamp convenience
remote panic alarm (standard on North American specification vehicles and as a dealer option in other markets)
Inputs and Outputs
The keyless entry/computer operated lock system receives inputs from the following:
ignition switch (ACC and ON positions)
door ajar switches
hood switch
luggage compartment switch
remote transmitter
The Generic electronics module (GEM) distributes outputs to the following:
door lock actuators
double locking motors
turn signals
alarm horn
luggage compartment latch
power window motors for global closing
Transmitter, Keyless Entry Remote
The keyless entry/remote operated lock system is completely independent in function but fully integrated within the GEM. The remote
control system consists of a transmitter and an antenna (radio frequency system).
The remote control transmitter for the radio frequency system will operate without the transmitter being directed at the vehicle. The normal
range between the transmitter and the antenna will be up to 10 meters for the USA, Canada and the rest of the world. The normal range
between transmitter and antenna will be up to five meters for the UK and Europe and three meters for Japan.
Before the remote control system can be used, each transmitter must be initialized to the vehicle. A maximum number of four transmitters
can be initialized to any vehicle. All remote transmitters must be initialized at the same time.
The keyless entry/remote operated locks will not operate when the ignition key is in the ignition switch.
Locking and Unlocking
The remote transmitter is integrated into the key and contains four buttons (lock, unlock, trunk release, headlamp convenience). To operate
the system:
Press the lock button once to activate the central locking system and the alarm system (if enabled).
Press the lock button twice within three seconds to activate the central locking system, double locking system, alarm system and the
interior scanning system (if equipped).
Press the unlock button once to deactivate the double locking, the alarm system is deactivated and only the driver door is fully unlocked
(this is programmable using the Jaguar approved diagnostic system or by pressing and holding the lock and unlock buttons simultaneously
for 4 seconds, the direction indicators will then flash to show the change of status from single point entry to central unlock).
Pressing the unlock button twice within three seconds will unlock the remaining doors (this is programmable using the Jaguar approved
diagnostic system).
Pressing the luggage compartment release button once releases the trunk. The vehicle must be unlocked and at vehicles speeds below 7
km/h (4 mile/h).
Press the headlamp convenience button once to activate the headlamp main beam function, press the headlamp convenience button again
to deactivate the headlamp main beam function. This function will automatically deactivate after 30 seconds.
Press the headlamp convenience button three times within three seconds to activate the alarm, press the headlamp convenience button
again three times within 3 seconds to deactivate the alarm.
Double Locking
Double locking prevents the interior door handles from unlocking the door.
Double locking is activated by turning the key in the driver door lock to the unlock position and then to the lock position within three
seconds or by pressing the lock button twice within three seconds on the remote transmitter.
Successful double locking is indicated by the turn signals flashing twice, one short flash followed by a long flash.
Double locking will be inhibited if the GEM senses the hood, a door or the luggage compartment is ajar or open. The GEM receives its input
from the door ajar switches.
If the vehicle battery becomes discharged after the double locking has been activated, opening the drivers door with the key will
mechanically deactivate the double locking on the drivers door only.
