Locking and unlocking with KEYLESS-GO-card
Unlocking:
Grasp any door handle. All turn signal lamps blink once
to indicate that the vehicle is unlocked.
The KEYLESS-GO-card can be programmed for two
kinds of unlocking modes (see below):
Selective unlocking mode –
Grasp driver’s door handle to unlock driver’s door and
fuel filler flap.
Grasping the passenger door or a rear door, centrally
unlocks the vehicle.
Global unlocking mode –
Grasp any door handle to unlock both doors, fuel filler
flap, and trunk.
For choosing global or selective mode on KEYLESS-GO-
card, see page 43.Notes:
The door which was unlocked, can be opened
immediately after the audible click. The other door can
be opened after its lock button rises up.
If the trunk was previously locked separately, it will
remain locked, see page 53.
The presently active unlocking mode (selective or
global) can be determined by pressing the button on the
KEYLESS-GO-card (see page 43 for changing mode).
If within 40 seconds of unlocking with the
KEYLESS-GO-card, neither door nor trunk is opened,
the electronic key is not inserted in the starter switch,
or the central locking switch is not activated, the vehicle
will automatically lock.

Automatic central locking
With the automatic central locking system activated, the
doors and trunk are locked at vehicle speeds of
approximately 9 mph (15 km / h) or more. The fuel filler
flap remains unlocked.
The automatic central locking function can be switched
on or off. See page 138 for “Individual settings”.
Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approximately 9 mph (15 km /
h) or more.
If a door is opened from the inside at speeds of
approximately 9mph (15km/h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: operation position, see page 228), the
vehicle doors will lock if the left front wheel as well as
the right rear wheel spin at vehicle speeds of
approximately 9 mph (15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See page 138
for “Individual settings”.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
