The vehicle is equipped with a central locking system which makes it possible
to unlock / lock all the doors, the fuel filler flap and boot lid simultaneously.
The door unlocking can be adjusted individually » page 47.
The unlocking of the vehicle is displayed by the turn signal lights flashing
twice.
If you unlock the vehicle and do not open a door or the boot lid within the next
45 seconds, the vehicle will lock again automatically.
The locking of the vehicle is displayed by the turn signal lights flashing once.
If the driver's door has been opened, the vehicle cannot be locked.
If the doors or the boot lid remain open after the vehicle doors have been
locked, the turn signal lights do not flash until they have been closed.

If the “Reboot” interface is not displayed, you must manually restore the web browser display.
44Operation

WARNING■Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ised persons (e.g. children) could lock the vehicle, turn on the ignition or
start the engine - danger of injury and accidents!■
When leaving the vehicle, never leave people who are not completely in-
dependent, such as children, unattended in the vehicle. These individuals
might not be able to leave the vehicle on their own or to help themselves.
At very high or very low temperatures can be fatal!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the key grooves clean. Impurities (textile fibres, dust etc.) have a nega-
tive effect on the functionality of the locking cylinder and ignition lock.

■
The remote control may be affected by signal superimposition by transmit-
ters close to the car.■
The range of the remote control key is about 30 m. The battery must be re-
placed if the central locking only reacts to the remote control at a distance of
less than 3 m away » page 159.

Unlocking/locking - KESSYFig. 31
Vehicle unlocking / vehicle locking
Read and observe
and on page 45 first.
The KESSY system (Keyless Entry Start Exit System) enables unlocking and
locking of the vehicle without actively using the remote control key.

the
vehicle.
When unlocking/locking the vehicle, the key must be at a maximum distance
of approximately 1.5 m from the front door handle.
Information on locking
On vehicles fitted with automatic gearbox, the selector lever must be moved
into the position P before unlocking.
The vehicle cannot be locked if the ignition has not been turned off.
After locking the car, it is not possible to unlock it within the next 2 seconds by touching the door handle. This can be used to check whether the vehicle is
locked.
Protection against inadvertently locking the key in the vehicle
If one of the doors is closed after locking the vehicle and the key with which
the vehicle was locked remains in the passenger compartment, the vehicle is
automatically unlocked. After automatically unlocking, the turn signal lights
will flash four times. If no door is opened within 45 seconds, the vehicle is au-
tomatically locked again.
If the boot lid is closed after locking the vehicle and the key with which the vehicle was locked remains in the luggage compartment, the lid is automatical-
ly unlatched (partially opened). After automatically unlocking, the turn signal
lights will flash four times. The boot lid remains unlatched (partially opened);
the other doors remain locked.
CAUTION
Some types of gloves can affect the unlocking or locking device via the sen-
sors in the door handle.

Prerequisites for locking / unlocking with the central locking button
The vehicle is not locked from the outside.
None of the doors are open.
›
To lock , press the
button » Fig. 32 .
Locking is displayed in the button by the illumination of the
symbol.
The following applies after locking. ▶ Opening the doors and the boot lid from the outside is not possible.
▶ The doors can be unlocked and opened from the inside by a single pull on the
opening lever of the respective door.
WARNINGDoors locked from the inside make it difficult for rescuers to get into the
vehicle in an emergency – danger to life!46Operation

SafeLockRead and observe
and on page 45 first.
SafeLock prevents the doors from behind opened from inside as well as win-
dow operation. This makes an attempted break-in to the vehicle more difficult.
Activating
SafeLock is activated when the vehicle is locked from the outside.
This function is pointed out by the following message on the display of the in-
strument cluster after the ignition is switched off.
Check SAFELOCK! Log book!CHECK SAFELOCK
Activation display
When SafeLock is activated the warning light in the driver's door flashes for 2
seconds in rapid succession, then starts to flash at longer intervals.
Deactivating
▶ By locking twice within 2 seconds.
▶ or: by deactivating the interior monitor and the towing protection
» page 49 .
The warning light in the driver door flashes rapidly for about 2 seconds, then
goes out and starts to flash at longer intervals after about 30 seconds.
If the vehicle is locked and the SafeLock system is switched off, the door can
be opened separately from the inside by a single pull on the opening lever.
The SafeLock switches on the next time the vehicle is locked.
WARNINGIf the car is locked and the SafeLock system activated, no-one may remain
in the car as it will then not be possible to either unlock a door or open a
window from the inside. The locked doors make it more difficult for rescu-
ers to get into the vehicle in an emergency – risk to life!
Individual settings
Read and observe
and on page 45 first.
The following functions of the central locking system can be set individually in
the Infotainment » Owner's Manual Infotainment .
All doors
The function allows you to unlock all doors, the boot lid and the fuel filler flap.
Single door
The function allows you to only unlock the driver's door and the fuel filler flap
with the radio remote control. KESSY allows the unlocking of a single door
which is in the vicinity of the key, as well as the fuel filler flap. The other doors
and the boot lid are only unlocked once the door handle is unlocked or
touched.
Doors on a vehicle side
This function enables you to unlock both doors on the driver's side and the
fuel filler flap with the radio remote control unit. KESSY allows the unlocking of
both doors which are in the vicinity of the key, as well as the fuel filler flap. The
other doors and the boot lid are only unlocked once the door handle is un-
locked or touched.
Automatic locking/unlocking
This function enables the locking of all doors and the boot lid from a speed of
15 km / h. Opening the doors and the boot lid from the outside is not possible.
The renewed unlocking of the doors and the boot lid is carried out when the
ignition key is removed or when the door is opened from inside (depending on
the individual setting for the central locking system).
