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.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Emergency access to the vehicle is provided by two concealed key barrels: one located in the front left-hand door handle and
one located on the underside of the luggage compartment lid finisher. An emergency, removable key blade is fitted into the
Smart Key.

Operation of either key barrel unlocks the vehicle but does not disarm the alarm system. The key barrels in the door and
luggage compartment lid are concealed by a plastic cover which can be removed by inserting the blade of the emergency key
into a slot in the cover.
Locking and unlocking conditions using the emergency key in the door key barrel:
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.
Central locking and unlocking can also be performed using lock and unlock buttons on the vehicle's fascia. 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 of the vehicle from inside and outside of the
vehicle. The system is operated using buttons on the Smart Key, which transmits radio frequency signals to the central locking
radio frequency receiver.

The system provides additional security by double-locking the doors from outside the vehicle if the lock button, on the Smart
Key, is pressed twice within 3 seconds; this function is not applicable in North American Specification (NAS) and Japanese
markets.

Additional buttons on the Smart Key provide for the convenience operation of the luggage compartment lid release, headlamp
delay and panic alarm functions. A global open or close feature is also available in certain markets using the lock/unlock
buttons.

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.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
The passive entry system is controlled by the keyless vehicle module and five low frequency antennas. One antenna located in
each door handle and one antenna located behind the rear bumper cover.

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 central locking radio-
frequency receiver and passed to the keyless vehicle module which checks and approves the code as valid. Once the handle is

and is connected at the opposite end to the LH pivot housing via a crank. The LH pivot housing crank is fitted with a second link rod which is connected directly to the crank on the RH pivot housing.
The motor crank converts rotary motion from the motor output shaft into linear movement of the link rods. The cranks
connected to each pivot housing, convert the linear motion of the link rods back to rotary motion of the pivot housings. This
rotary motion is passed to the wiper arms and blades causing the blades to wipe an arc across the windshield.

Each wiper arm is located on a taper spline on the respective pivot housing. A nut is screwed on the end of the pivot housing
shaft and positively secures the wiper arm on the taper spline.

The wiper blades are attached to the wiper arms with a quick release fittings. The blades are of the flat blade type. These
blades have an integral spring along their full length which curves the blade to match the windshield and provides even blade
to windshield contact pressure along the entire length of the blade.

The reservoir is a plastic moulding and is secured in the wheel arch with 2 screws and washers and a scrivet. A level sensor is located in the reservoir and is connected to the CJB. The reservoir is fitted with a washer pump which supplies pressurized washer fluid to the windshield washer jets mounted on the wiper arms.

A vehicle fitted with optional headlamp washers is fitted with a larger reservoir and an additional pump for the headlamp
washers. The larger reservoir is identifiable by a letter 'B' moulded on the casing and has a capacity of 5.5 liters. Reservoirs
moulded with the letter 'A' are for use on vehicles with windshield washers only and have a capacity of 4.4 liters.
A filler cap is located at the top of the reservoir and is accessible from the engine compartment.

The pumps are located in rubber sealing grommets in holes in the reservoir and secured with clips. The pump fluid hoses have
quick release connectors which mate with the pumps. The fluid level sensor is a push fit into a sealing grommet in one side of
the reservoir body.
