Central locking

General information

The term “vehicle key” refers to the remote con-

trol key or convenience key*. The convenience

key* is a remote control key with special func-

tions ðpage 41 and ðpage 97.

WARNING

Automatic locking

– If you leave the vehicle, turn off the ignition

and take the key with you. This applies par-

ticularly when children remain in the vehi-

cle. Otherwise, children could start the vehi-

cle or operate electrical equipment (such as

power windows), which increases the risk of

an accident.

If you unlock the vehicle but then do not open

any of the doors, the luggage compartment, or

the hood within a short period time, the vehicle

locks again automatically. This feature prevents

the vehicle from being accidentally left unlocked

for a long period of time.

– No one, especially children, should stay in

the vehicle when it is locked from the out-

side, because the windows can no longer be

opened from the inside. Locked doors make

it more difficult for emergency workers to

enter the vehicle, which increases the risk of

death.

Automatic locking (Auto Lock)

The Auto Lock function locks all doors and the

luggage compartment lid once the speed exceeds

approximately 9 mph (15 km/h). The vehicle will

unlock again if the unlock function in the central

locking switch is pressed, the “P” position is se-

lected, or the ignition is turned off.

– Applies to: child safety lock: No one, espe-

cially children, should stay in the vehicle

when the child safety lock is activated, be-

cause the rear doors and the windows can

no longer be opened from the inside. This

increases the risk of death.

You can open the doors individually from the in-

side by pulling the door handle one time. To open

the rear doors individually, you must pull the

door handle twice.

In the event of a crash with airbag deployment,

the doors will also automatically unlock to allow

access to the vehicle.

Description

Unintentionally locking yourself out

All doors and the luggage compartment lid can

be centrally unlocked and locked at once. You can

select in the MMI if the entire vehicle or only the

driver's door should unlock when unlocking the

vehicle ðpage 37. The turn signals flash twice

when you unlock the vehicle and flash once when

you lock the vehicle. If they do not flash when

locking, check if all doors and lids are closed.

Only lock your vehicle when all of the doors and

the luggage compartment lid are closed and

there is no key in the vehicle. This reduces the

risk of locking yourself out accidentally.

The following features help to reduce the risk of

locking your vehicle key in the vehicle:

– If the driver's door is open, the vehicle cannot

be locked by pressing the  button on the vehi-

cle key or by touching the locking sensor* on a

door.

Depending on the vehicle equipment, you may

have different options for centrally unlocking and

locking your vehicle.
