General notes
Bear in mind that the engine can be started by any of the vehicle occupants if there is a KEYLESS-GO key in the vehicle.
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a
conventional SmartKey. Unlock the vehicle
by using KEYLESS-GO, for instance, and lock
it using the button on the SmartKey.
When locking or unlocking with KEYLESS-GO, the distance between the SmartKey and the corresponding door handle must not be greater than 3 ft (1 m).
KEYLESS-GO checks whether a valid
SmartKey is in the vehicle by periodically
establishing a radio connection between the
vehicle and the SmartKey. This happens:
• when the external door handles are
touched
• when starting the engine
• while the vehicle is in motion
■ To unlock the vehicle: touch the inner surface of the door handle.
■ To lock the vehicle: touch sensor surface 1.
■ Convenience closing feature: touch recessed sensor surface 2 for an extended period.

If you pull on the handle of the tailgate, only the cargo compartment of the vehicle is unlocked.
