System Operation
The hinged panels are secured with latches and strikers. A remotely operated central locking system controls the locking and unlocking of the door and luggage compartment latches. A radio frequency Smart Key allows the vehicle to be locked and unlocked by pressing the appropriate handset buttons. Two levels of central locking system are available: remote central locking and an optional passive entry system.
The passive entry and associated passive start system allows the driver to unlock and start the vehicle without using a vehicle key in a door-lock or ignition switch. The passive entry system is an optional fitment while the passive start system is a standard fitment on all vehicles. The passive start system is combined with the passive anti-theft immobilization system. For additional information, refer to Anti-Theft - Passive Description
Emergency access to the vehicle is provided by a concealed key barrel located in the front left-hand door handle. The key barrel is concealed by a plastic cover which can be removed by inserting the blade of the emergency key into a slot in the cover. The removable emergency key blade is located in the Smart Key. There is no emergency unlocking key aperture in the luggage compartment lid.
Operation of the key barrel unlocks the vehicle but does not disarm the alarm system. Locking and unlocking conditions using the emergency key in the door key barrel are:
- If the alarm is not armed the vehicle can be centrally unlocked.
- If the alarm is armed the door only can be opened and the alarm will be triggered.
- The vehicle cannot be double locked or the alarm system armed using the emergency key.
The vehicle can be centrally locked and unlocked from inside using the interior handle release levers on the front doors only. The driver can select locking options, single point entry or drive away locking for example, from a menu available on the touch screen.
Central Locking - Radio Frequency Remote System
The radio frequency central locking system provides locking and unlocking from inside the vehicle and outside within a 20 meter range. The system is operated using buttons on the Smart Key, which transmits radio frequency signals to the radio frequency receiver.
Additional buttons on the Smart Key provide for the convenience operation of the headlamp delay, panic alarm and luggage compartment lid release. For additional information, refer to Body Closures Body Closures
Depending on vehicle market functions offered by the Jaguar Smart Key include:
- Double locking the doors from outside the vehicle if the lock button on the Smart Key is pressed twice within 3 seconds.
- Drive-away locking - switched on or off by the customer using the vehicle security settings menu available on the touch screen.
- Single or two stage unlocking - single-stage unlocking unlocks all doors with a single press; two-stage unlocking unlocks the driver's door only with a single press and all other doors with a second press.
Changing the unlocking mode between single stage and two stage also affects the unlocking mode for passive entry (see below). The single or two-stage unlocking function can be switched on or off, as can remote global open or close for the electric windows using the vehicle security settings menu available on the touch screen.
Actuated from the front door levers only, the doors can be locked from inside the vehicle by pressing the interior door release levers inwards and unlocked by pulling the levers. The Touch-screen incorporates a valet mode feature which inhibits access to the boot and the glove box while also limiting the use of the Touch-screen.
On leaving the vehicle with passive entry the user must press an external button on the door handle once to centrally lock the vehicle or twice within 3 seconds to double lock. The user has a further 3 seconds to pull the door handle to check the vehicle is locked without the Jaguar Smart Key proximity function unlocking the door again. Pulling the handle after the 3 seconds has lapsed will unlock the door as normal.
If any aperture is not fully closed when the locking process is initiated, either passively or by Jaguar Smart Key transmitter, the locking function will be inhibited and an audible error indication will be given. If the ignition is left on an audible warning will be given if the user exits the vehicle, if the user attempts to lock the vehicle (ignition on), another audible indication will be given, and the locking function will be inhibited.
If the door is closed without locking and no key left in the car the ignition will be switched off immediately. If the ignition is left on at any time without starting the vehicle it will switch off automatically after 60 minutes.
If the door is opened by the mechanical key, the full alarm system will sound until the user enters the vehicle and presses either the start/stop button, remote unlock button, or places the Jaguar Smart Key next to the IAU (immobilizer antenna unit) whilst pressing the start/stop button.
The fuel filler flap is locked by the global locking function. It is not locked by drive-away locking, or if doors are locked from inside the vehicle using the handles.
Passive Entry
On vehicles fitted with the optional passive entry system, the vehicle can be unlocked without the use of a key blade or pressing buttons on the Smart Key. The Smart Key operates the passive entry system in addition to the passive start system. For additional information, refer to Anti-Theft - Passive Description
The passive entry system is controlled by the keyless vehicle module and low frequency antennas strategically situated within the vehicle; including one in each door handle. When in the vehicle the antennas ensure the Jaguar Smart Key is always within the active transmission zone of the antennas, wherever the key is placed inside the vehicle. For this reason the orientation and positioning of the antennas is critical to the correct functioning of the system.
When a vehicle door handle is pulled to the first five-percent of its travel and the Smart Key is within one meter of the handle; the Smart Key receives the low-frequency signal transmitted from the keyless vehicle module.
The Smart Key responds with a radio frequency transmission of its authorization code. The radio frequency signal is received by the radio-frequency receiver and passed to the keyless vehicle module which checks and approves the code as valid.
Once the handle is pulled to eighty percent of its travel the keyless vehicle module then drives the fast latch directly to allow the door to be opened. The keyless vehicle module also transmits an unlock request to the CJB (central junction box). The CJB then passes an unlock request to the door modules.
Locking of the vehicle is performed by pressing one of the buttons located on each exterior door handle, with the Smart Key within a one meter range of the vehicle. When the door handle button is pressed, the keyless vehicle module transmits a low-frequency signal via the low-frequency handle antenna to the Smart Key. The Smart Key transmits a radio frequency signal which is verified by the keyless vehicle module and allows the doors to be locked or double locked and the alarm system to be armed.
To double lock the vehicle, the button on the exterior door handle must be pressed twice within three seconds, with the Smart Key within one meter range of the vehicle. If a door, engine-compartment lid or the luggage compartment lid is ajar when an attempt to lock the vehicle is made, an error tone is emitted and no locking action will occur. For additional information, refer to Anti-Theft - Active Anti-Theft - Active
When unlocking the vehicle using passive entry with single stage unlocking selected and a valid Jaguar Smart key present, pulling the door handle will centrally unlock the vehicle. When the vehicle is configured for two stage unlocking and the drivers door handle is pulled with a valid smart key present only the drivers door will unlock, however if a passenger door handle is pulled with a valid smart key present the vehicle will centrally unlock. If the boot is unlocked and opened with a valid smart key present all the doors remain locked.
Provided the key is within range of the desired point of entry, approximately one meter from vehicle door or luggage compartment lid, it need only be on the driver's person, for example in a pocket, handbag, or briefcase to provide access to the vehicle. The driver has to pull the door handle, or press the luggage compartment lid release button and the vehicle then unlocks according to the current security setting; either single-stage or two-stage entry.
NOTE:
Passive unlocking of the luggage compartment lid does not unlock the rest of the vehicle.
Engine Compartment Lid Latches
Two engine-compartment lid latches are located on the front crossmember. An engine-compartment lid release lever is located below the instrument panel on the left-hand 'A' pillar and is connected with a cable to the latches. An engine-compartment lid ajar switch is integrated in the engine-compartment lid latch.
Door Latches
The door latches are located at the rear of each door and engage with a striker on the adjacent pillar. Each door latch motor assembly contains micro-switches for lock, unlock and door ajar. Motors provide for the central door locking and the double locking feature. The electrical control for the door latch components is provided by the CJB via the driver's and passenger door modules.
The interior door handles are connected by a cable to the latch release mechanisms. The interior door handles also incorporate a locking facility to allow the doors to be locked from inside the vehicle when all the doors are closed. If a door is ajar the locking feature is inhibited.
