Passive Entry

NOTE: With the keyless vehicle system, the doors can be unlocked either individually or 'globally'.

The programming process is the same as on vehicles without a keyless vehicle system.

Unlocking the vehicle

When a door handle or the release button on the liftgate is actuated, the relevant exterior antenna emits a low frequency signal.

Three exterior antennas are installed on the vehicle:

  • one in the driver door handle,
  • one in the passenger door handle,
  • one behind the bumper.

The passive vehicle key is then activated and it transmits a coded radio frequency signal.

The coded radio frequency signal from the passive key is received by the radio frequency receiver.

The radio frequency receiver transfers the signal to the keyless vehicle module.

If the module recognises a valid key signal, the actuated door or liftgate is unlocked. Unlocking of this door or liftgate is performed directly by the module.

If global unlocking is activated, the module transmits the unlocking request over the MS-CAN to the GEM (generic electronic module). The GEM then activates the individual door modules.

NOTE: .

  • If the vehicle goes over 5 days without being unlocked, the system enters energy saving mode. This mode prevents excessive load on the vehicle battery
  • In this mode, the response time of the keyless vehicle system during unlocking is slightly longer. Energy saving mode is deactivated again when the vehicle is unlocked again once after more than 5 days.

Passive Start

NOTE: In order for engine starting to be enabled it is necessary for a valid passive key to be present inside the vehicle.

A total of four internal antennas are installed, for identification of the passive vehicle key:

  • one behind each of the front seats,
  • one under the floor console,
  • one behind the rear seat bench.

Three states can be switched to via the start/stop button:

  • Switch on the ignition
  • directly start the engine,
  • Switch off the engine.

Start the engine

The following options are available:

  • Ignition ON: - actuate the start/stop button.
  • Starting the engine from ignition ON or directly from ignition OFF:

 actuate the clutch pedal and the start/stop button.

When the start/stop button is pressed, the interior antennas of the keyless vehicle module are activated.

The passive vehicle key is then activated and it transmits a coded radio frequency signal.

The coded radio frequency signal from the passive key is received by the radio frequency receiver.

The radio frequency receiver transfers the signal to the keyless vehicle module.

For security reasons, a code enquiry is made to the PCM before the vehicle can be started.

The coding enquiry is made over the HS-CAN.

Starting is only enabled once confirmation has been received from the module.

Switching off the engine

The engine is switched off by actuating the start/stop button, provided the vehicle is stationary (vehicle speed = 0 km/h).

In an emergency, the engine can be switched off at any speed as follows:

  • By pressing the start/stop button three times within three seconds.
  • By keeping the start/stop button pressed for two seconds.
