Indicator lamp
The control is equipped with an indicator lamp ⇒ Fig. 49 (arrow). This displays the following
statuses:
Off: all voice services are deactivated.
Flashing red for approx. 20 seconds after the ignition is switched on: at least one voice service is

Vehicle unlocking is confirmed by all the turn signals flashing twice and locking by the turn signals
flashing once.
Locking and unlocking the boot lid
When the vehicle is locked, the boot lid will be unlocked automatically if you open it when a vehicle
key is located within the operating range of the boot lid ⇒ Fig. 52 .
The boot lid is locked automatically after it is closed.
If the vehicle is completely unlocked, the boot lid will not lock automatically when closed.
Temporarily deactivating Keyless Access
Keyless Access can be deactivated temporarily as described below so that the vehicle cannot be
unlocked and started due to misuse by unauthorised third parties.
Lock the vehicle with the button in the vehicle key.
In addition, touch the sensor on the outside of the door handle ⇒ Fig. 53Ⓑ once within five
seconds. Do not reach into the door handle.
Keyless Access is temporarily deactivated.
Check deactivation by waiting for at least ten seconds and then pull the door handle again. It should
not be possible to open the door.
When the vehicle is next unlocked, it can be unlocked only using the vehicle key. The Keyless Access
locking and starting system is reactivated the next time the vehicle is unlocked.
Operating the convenience functions
All electric windows and the glass roof can be closed automatically.
Keep a finger on the sensor ⇒ Fig. 53Ⓑ of the driver or front passenger door handle for a few
seconds until the windows and glass roof are closed.
The sensor functions can be set in the Vehicle settings menu in the Infotainment system
⇒ Infotainment system controls and displays .
The unlocking function is deactivated for a few seconds so that you can check that the vehicle has
been locked successfully.
If the message Keyless Access system faulty appears on the instrument cluster display, there may be
a malfunction in the Keyless Access system. Go to a qualified workshop.
If there is no vehicle key in the vehicle or if it is not detected, a message will be shown on the
instrument cluster display. This may occur if the vehicle key is subject to interference by another
The vehicle can be locked only if the ignition has been switched off or the driver has switched off the
engine before leaving the vehicle.
A symbol in the instrument cluster display ⇒ Displays indicates if one or more doors are not closed
properly. Do not drive on! Open the appropriate door and then close it again.
This symbol is also visible when the ignition is switched off and will go out a few seconds after the
vehicle has been locked when all doors are closed.
WARNING
A door which is not closed properly could open suddenly while the vehicle is in motion. This could
lead to serious injuries.
Stop as soon as possible and close the door.
Make sure that the door is closed properly and that the lock has engaged. The closed door must be
flush with the surrounding body panels.
Doors should be opened or closed only when you are sure that nobody is in their path.
WARNING
Any door being held open by the door arrester could close unexpectedly in strong winds or if the
vehicle is on a slope. This could lead to injuries.
Always hold doors by the handle when opening and closing doors.
WARNING
The opening and closing paths of the doors and boot lid are potential danger areas where injury can
occur.
The doors and boot lid should therefore be opened or closed only when you are sure that nobody is
in their path.
WARNING
Careless locking of the doors can cause serious injuries.
If the vehicle is locked from the outside, the doors and electric windows cannot be opened from the
inside.
The central locking system locks all doors. Locking the vehicle from the inside can prevent the doors
from being opened unintentionally and unauthorised persons from entering the vehicle. However,
locked doors can delay assistance to passengers inside the vehicle in the event of an accident or
emergency.
Never leave children or people requiring assistance alone in the vehicle. All doors can be locked from
the inside using the central locking button. This may mean that people lock themselves in the
vehicle. People locked in the vehicle may be subjected to very high or very low temperatures.
Temperatures inside a locked vehicle may become extremely hot or cold, depending on the season.
This can cause serious injuries and illness or fatalities, especially in the case of small children.
Never leave anyone inside a locked vehicle. People in the vehicle could become trapped in an
emergency and will not be able to get themselves to safety.
NOTICE
When carrying out manual opening or closing, remove parts carefully and install them again
correctly in order to avoid damage to the vehicle.
