Please note that the sensors in the door handles can be activated by a powerful jet of water or
steam if a valid vehicle key is simultaneously within the operating range. If at least one window is
open and sensor surfaces on the door handles are continuously activated, all windows will close. All
windows could open if the jet of water or steam is moved away from the door handle sensors briefly
and then moved back again ⇒  .

It may not be possible to lock or unlock the vehicle using the Keyless Access if the 12-volt vehicle
battery or button cell in the vehicle key is weak or discharged. The vehicle can be locked or unlocked
manually ⇒  .

If there is no valid vehicle key in the vehicle or if it is not detected, a corresponding message will be
shown on the instrument cluster display. This may occur if the vehicle key is exposed to interference
from another radio signal or is covered by another item, e.g. an aluminium case ⇒ Starting and
stopping the engine .
Anti-theft alarm
Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.

Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Boot lid cannot be opened or closed
Check whether the boot lid is blocked by an obstacle. The boot lid can be moved by hand. You will
need to use increased force for this.
The drive switches off automatically in order to prevent overheating if the boot lid is operated too
frequently in a short space of time. Until the drive has cooled down, the boot lid can be opened and
closed by hand using more force than usual.
When you tow a trailer, the electrical boot lid can only be opened and closed on the boot lid
⇒ Trailer towing .
The boot lid must be closed by hand if the 12-volt vehicle battery or fuse is disconnected or faulty.
All turn signals flash four times
The vehicle key used last is still in the vehicle.
Boot lid is stiff
At outside temperatures below freezing point, the opening mechanism cannot always lift the
partially opened boot lid automatically. In this case, guide the boot lid further up by hand.
Windows

Ensure that nobody obstructs the path of the window, especially if a window is being closed when
the roll-back function is not active.
The roll-back function does not prevent fingers or other body parts from being pressed against the
window frame and being injured.

The roll-back function is also activated if the windows are closed using the vehicle key for
convenience closing.
Troubleshooting
One-touch opening and closing does not work
One-touch opening and closing is deactivated if the 12-volt vehicle battery has been disconnected or
discharged while the windows were not fully closed. The function must then be reset:
Switch on the ignition.
Close all windows and doors.
Pull up the button for the respective window and hold it in this position for several seconds.
Release the button, then pull it up again and hold it in this position. The one-touch function is now
ready for operation again.
The one-touch function can be restored for individual windows or for several windows at the same
time.
Closing windows without roll-back function
Attempt to close the window again within a few seconds by holding the button. The roll-back
function will be deactivated for a small part of the path of the closing window.
If the closing procedure takes longer than several seconds, the roll-back function will be reactivated.
If it is still stiff or obstructed, the window will stop and open again automatically.
Please go to a qualified workshop if the window still cannot be closed.

trailer with rear fog light is electrically connected to the vehicle ⇒ Trailer towing .
Light functions
Side lights
If the side lights are switched on, both headlights light up with the side lights, parts of the tail
light clusters, the number plate lighting and the buttons in the centre console and the dash panel.
The daytime running lights also switch on when the ignition is switched on.
If the vehicle is not locked from outside when the ignition is switched off, the continuous parking
light on both sides of the vehicle switches on automatically after around 10 minutes to reduce 12-
volt vehicle battery discharge ⇒ Switching the parking lights on and off .
Automatic headlights
If the automatic headlights are switched on, the vehicle lighting and the instrument and
switch lighting will switch on and off according to the light conditions. When the lights are switched
on, the indicator lamp lights up yellow.
The automatic headlights are merely an aid and will not always be able to detect all driving
situations.
In vehicles with a corresponding equipment level, the switch-on time of the automatic headlights
can be adjusted in the Infotainment system in the Vehicle settings menu ⇒ Infotainment system
controls and displays .
Cornering light
A cornering light is switched on when turning slowly or travelling around very tight bends.
Signal tones if lights are not switched off

Switch off the ignition.
Lock the vehicle from the outside.
Automatic switch-off of side lights and parking lights
If the battery capacity is not sufficient for the side lights or parking light to remain switched on for
two hours, the 12-volt vehicle battery can be discharged to such an extent that it is no longer
possible to start the engine ⇒ .
In the case of standing times of more than two hours, the vehicle will detect a weak 12-volt vehicle
battery and switch off the side lights or parking light so that the engine can still be started.

WARNING
Accidents and serious injuries can occur if the vehicle is parked without sufficient illumination, as
other road users might have difficulty seeing the vehicle, or may not see it at all.
Always park the vehicle safely and with sufficient lighting. Observe any applicable local regulations.
If the vehicle lighting is required for several hours, switch on the right or left parking light if possible.
The illumination time of the parking light on one side is generally twice as long as for continuous
parking light on both sides of the vehicle.
Coming Home and Leaving Home function (orientation lighting)
The Coming Home and Leaving Home function lights up the area immediately surrounding the
vehicle when you get in or out of the vehicle in darkness.
Not in China: the Coming Home function is switched on manually. In contrast, the Leaving
Home function is controlled automatically by a rain/light sensor.
Only in China: the Coming Home and Leaving Home function is controlled automatically by a

Depending on the equipment level, the background lighting provides indirect light in various areas of
the vehicle interior.
The front footwell may also be illuminated.
The brightness of the background lighting can be adjusted in the Infotainment system in the Vehicle
settings menu ⇒ Infotainment system controls and displays .

The lights go out when the vehicle is locked or after a delay of a few minutes when the vehicle key is
removed from the ignition lock. This prevents the 12-volt vehicle battery from discharging.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
