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.
SAFELOCK
First read and observe the introductoryinformation and safety warnings⇒Introduction
With some equipment levels, the vehicle may have a SAFELOCK mechanism.
SAFELOCK deactivates the door release levers if the vehicle has been locked. This makes it more

Press the button on the vehicle key once.
Press the button on the vehicle key twice in quick succession.
Vehicles with the Keyless Access locking and starting system: touch the sensor on the outside of the
door handle twice⇒ Unlocking or locking the vehicle with Keyless Access .
OR: press the central locking button in the driver door once ⇒ Central locking button .
There may be an indication of the activated SAFELOCK in the display of the instrument cluster
(SAFELOCK).

The following applies when SAFELOCK is deactivated:
The interior monitoring and the anti-tow alarm are activated and deactivated in the Vehicle settings
menu in the Infotainment system ⇒ Infotainment system controls and displays .
WARNING
Careless or unsupervised use of SAFELOCK can cause serious injuries.
Never leave other persons in the vehicle if the vehicle has been locked using the vehicle key. The
doors can no longer be opened from the inside once SAFELOCK is activated.
If you unlock the driver door mechanically using the vehicle key, only the driver door is unlocked,
and not the whole vehicle. The doors are released (but not unlocked) and the central locking button
is activated only when the ignition is switched on.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction
Indicator lamp lights up continuously
The red LED in the vehicle door flashes at short intervals and then lights up continuously.
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.
The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
The anti-theft alarm outputs acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
If a door is opened.
If the bonnet is opened.
If the boot lid is opened.
If the ignition is switched on with a valid vehicle key. (The alarm may sound briefly.)
If the 12-volt vehicle battery is disconnected.
If there is movement inside the vehicle (in vehicles with interior monitoring) ⇒ Interior monitoring
system and anti-tow alarm .
If the vehicle is lifted or towed (vehicles with anti-tow alarm) ⇒ Interior monitoring system and anti-
tow alarm .
If the vehicle is transported on a car ferry or by rail (vehicles with anti-tow alarm or interior
monitoring) ⇒ Interior monitoring system and anti-tow alarm .
If a trailer that is connected to the anti-theft alarm system is removed ⇒ Trailer towing .
Switching off the alarm
Unlock the vehicle using the unlocking button on the vehicle key.
If lightweight items such as loose pieces of paper or items hung from the interior mirror are left in
the vehicle.
If there is a mobile phone in the vehicle with the vibration alarm switched on.
Permanent deactivation of interior monitoring and the anti-tow alarm is not possible.
If doors or the boot lid are still open when the anti-theft alarm is activated, only the anti-theft alarm
will be activated. Interior monitoring and the anti-tow alarm are not activated until all doors and the
boot lid are closed.

Boot lid
Introduction
This chapter contains information on the followingsubjects:
⇒ Opening and closing the boot lid
⇒ Opening and closing the boot lid electrically
⇒ Unlocking the boot lid manually
⇒ Troubleshooting
The boot lid is locked and unlocked at the same time as the doors.
WARNING
Incorrect and unsupervised unlocking, opening or closing of the boot lid can cause accidents and
serious injuries.
The boot lid should be opened or closed only when you are sure that nobody is in its path.
Always check that the boot lid is closed properly once it has been closed. The closed boot lid must be
flush with the surrounding body panels.
Always keep the boot lid closed while the vehicle is in motion.
Never open the boot lid when loads, e.g. bicycles, are attached to it. The boot lid may close under its
own weight due to the additional load. Support the boot lid as necessary or remove the load from
the boot lid beforehand.
Close and lock the boot lid and all vehicle doors when the vehicle is not in use. Ensure that no one
remains in the vehicle.
Never leave children playing unattended in or around the vehicle, especially when the boot lid is
open. Children could climb into the luggage compartment and shut the boot lid, thereby trapping
themselves inside. 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.
WARNING
Serious injuries could occur if the boot lid is unlocked or opened incorrectly or without due care and
attention.
The boot lid may not always be detected as being unlocked if there is a carrier and items attached to
it. The boot lid may open suddenly while the vehicle is in motion if it is unlocked.
WARNING
If heavy snow or heavy items are located on the boot lid, the additional weight could cause the boot
lid to close on its own and cause severe injuries.
Never open the boot lid if it is covered by a large amount of snow or a load is attached to it, e.g. on a
luggage carrier.
Remove the snow or load before opening the boot lid.
WARNING
Do not push down the boot lid with your hand on the rear window. The rear window could shatter
and cause injuries.
NOTICE
Never use the opening mechanism to fix or hold a load. This could lead to damage that makes it
impossible to close the boot lid.
NOTICE
Never use the rear window wiper or the rear spoiler to fix or hold a load. This could cause damage
which results in the rear window wiper or rear spoiler being torn off.
Opening and closing the boot lid
