Opening and closing

Opening and closing
Central locking
You can lock and unlock the vehicle centrally. You
have the following options:
— Remote control key > page 21
— Sensors in the door handles* > page 22
— Lock cylinder on the driver's door > page 24,
or
— Interior central locking switch > page 23
Automatic locking function (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex-
ceeded approximately 9 mph (15 km/h).
The vehicle can be unlocked if the opening func-
tion in the central locking system switch is used
or one of the door handles is pulled. The Auto
Lock function can be switched on and off in the
Infotainment system > page 23.
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close. You can set in the Infotainment
system whether only the driver's door or the en-
tire vehicle should be unlocked when unlocking
=> page 23.
Turn signals
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.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the
remote control key is not in the vehicle. This re-
duces the risk of locking yourself out accidental-
ly.
18
The following conditions prevent you from lock-
ing your remote control key in the vehicle:
— If the driver's door is open, the vehicle cannot
be locked by pressing the & button on the re-
mote control key or by touching the locking
sensor* on a door.
— If the most recently used convenience key* is
inside the luggage compartment, the luggage
compartment lid will automatically open again
after closing it.
— If the convenience key* that was last used is de-
tected inside the vehicle, then the vehicle can-
not be locked from the outside > @.
@) Note
Applies to: vehicles with convenience key
The following applies when locking the vehi-
cle:
— If the vehicle key that was last used is de-
tected inside the passenger compartment,
then the vehicle cannot be locked from the
outside using the sensor. Take the vehicle
key with you and lock the vehicle again. Oth-
erwise, the vehicle will not be protected
against unauthorized access.
— If you try to lock the vehicle using the but-
ton on the vehicle key while the front pas-
senger's door is open, and you accidentally
place the vehicle key inside the passenger
compartment and close the door, the vehi-
cle will lock at first. But if the keyless sys-
tem detects a vehicle key inside the vehicle
after it locks, then the vehicle will unlock
again. The turn signals will flash several
times to indicate this. If you do not open the
vehicle to remove the vehicle key within a
brief period, then the vehicle will lock auto-
matically. This prevents the vehicle from be-
ing left unlocked for long periods of time.
The vehicle key will then be locked inside
the vehicle.
— If the luggage compartment lid closes and
the system detects that the last conven-
ience key* that was used is inside the lug-
gage compartment, then the luggage com-
partment lid will open again. The turn sig-
nals will flash several times to indicate this.
The doors will lock. Always take the vehicle >

After that, it will only be possible to unlock the
vehicle using the remote control key or by me-
chanically unlocking the lock cylinder. Keyless ac-
cess will be active again after the next time the
vehicle is locked/unlocked.
You can unlock and lock the vehicle at every door.
The convenience key must no be more than ap-
proximately 5 feet (1.5 m) away from the door
handle. The function should not be impaired if
the convenience key is in your jacket pocket or in
your briefcase, for example.
If you hold the door handle while locking, this can
impair the locking function.
The door cannot be opened for a brief period di-
rectly after locking it. This way you have the op-
portunity to check if the doors locked correctly.
The settings in the Infotainment system deter-
mine if the entire vehicle or only one of the doors
is unlocked when unlocking the vehicle
=> page 23.

ZA WARNING
No one, especially children, should stay in the
vehicle when it is locked from the outside, be-
cause the windows can no longer be opened
from the inside > page 24. Locked doors
make it more difficult for emergency workers
to get into the vehicle, which puts lives at risk.

G) Tips
If your vehicle is left standing for a long peri-
od of time, note the following:
—To prevent the vehicle battery from dis-
charging, the energy management gradual-
ly switches off convenience functions that
are not needed. You then may no longer be
able to unlock your vehicle with the sensors.
— The system complies with United States FCC
regulations and ISED regulations
