Information on the Automatic Functions of the Restraint System
The function of the automatic front passenger airbag shutoff
A person in the front passenger seat must observe the following information:
- Sit correctly.
- Fasten the seat belt correctly.
The automatic front passenger airbag shutoff can activate or deactivate the front passenger airbag according to the situation.
Make sure you observe the following information:
- Status of the front passenger airbag: see “Function of the PASSENGER AIR BAG indicator lamps”.
- When installing a child restraint system on the front passenger seat, observe the vehicle-specific information.
Status of the front passenger air bag about the stature of the person:
- Front passenger airbag disabled: PASSENGER AIR BAG OFF lights up continuously.
The front passenger airbag will not be deployed in the event of an accident. If PASSENGER AIR BAG OFF is lit, no one may use the front passenger seat.
- Front passenger airbag enabled: PASSENGER AIR BAG ON lights up for up to 60 seconds or until both the PASSENGER AIR BAG ON and OFF indicator lamps go out.
- The front passenger airbag may be deployed during an accident. Observe the following information on the correct seat position.
Vehicles with rear seats: a person of smaller stature should use a rear seat.
System Limits
The front passenger airbag may otherwise be disabled by mistake, for example, in the following situation:
- The front passenger transfers their weight by supporting themselves on a vehicle armrest.
- The front passenger sits in such a way that their weight is lifted off the seat surface.
NOTE
Deployment of components of the restraint system when the front passenger seat is unoccupied
In an accident, the components of the restraint system may deploy unnecessarily on the front passenger side if:
- There are heavy objects on the front passenger seat.
- The seat belt tongue is engaged in the seat belt buckle of the front passenger seat and the front passenger seat is unoccupied.
- Store objects in a suitable place.
- Only one person should use each seat belt at any one time.
Depending on the accident situation detected, the window airbag on the front passenger side may deploy. The airbag will be deployed regardless of whether the front passenger seat is occupied.
The function of PRE-SAFE® (Anticipatory Occupant Protection)
PRE-SAFE® is able to detect certain critical driving situations and implement pre-emptive measures to protect the vehicle occupants.
PRE-SAFE® can implement the following measures independently of each other:
- Tightening the seat belts on the driver’s seat and front passenger seat.
- Closing the NOTE Damage caused by objects in the de windows.
- Vehicles with a sliding sunroof: closing the sliding sunroof.
- Vehicles with memory function: moving the front passenger seat to a more favourable seat position.
- Vehicles with memory function in the rear passenger compartment: moving the outer rear seats to a more favourable seat position.
- Vehicles with multicenter seats: increasing the lateral support by inflating the seat side bolsters of the seat backrest.
- PRE-SAFE® Sound: provided that the multimedia system is switched on, generating a brief noise signal to stimulate the innate protective mechanism of a person’s hearing.
NOTE
Damage caused by objects in the footwell or behind the seat.
The automatic adjustment of the seat position may result in damage to the seat and/or the object.
- Stow objects in a suitable place.
Backing up the PRE-SAFE® System Measures
If an accident does not occur, the pre-emptive measures that were taken are reversed. You will need to perform certain settings yourself.
- If the seat belt pre-tensioning is not reduced, move the seat backrest back slightly. The locking mechanism releases.
The function of PRE-SAFE® PLUS (Anticipatory Occupant Protection Plus)
PRE-SAFE® PLUS can detect certain impacts, particularly an imminent rear impact, and take pre-emptive measures to protect the vehicle occupants. These measures cannot necessarily prevent an imminent impact.
PRE-SAFE® PLUS can implement the following measures independently of each other:
- Tightening the seat belts on the driver’s seat and front passenger seat.
- Increasing brake pressure when the vehicle is stationary. This brake application is cancelled automatically when the vehicle pulls away.
If an accident does not occur, the pre-emptive measures that were taken are reversed.
System Limits
The system will not initiate any action in the following situations:
- When backing up
The system will not initiate any braking application in the following situations:
- Whilst driving
- When entering or exiting a parking space while.
The system will not initiate any action in the following situations:
- When backing up
The system will not initiate any braking application in the following situations:
- Whilst driving
- When entering or exiting a parking space while using Active Parking Assist4© 5 Settings 5 Vehicle 5 Occupant Protection.
The function of PRE-SAFE® Impulse Side
If an imminent side impact is detected, PRE-SAFE® Impulse Side can pre-emptively move the front seat vehicle occupant’s upper body towards the centre of the vehicle. It does this by rapidly inflating an air cushion in the outer seat side bolster of the seat backrest on the side on which the impact is anticipated. This increases the distance between the door and the vehicle occupant. Vehicles with E-ACTIVE BODY CONTROL: the body can also be slightly raised. If PRE-SAFE® Impulse Side has been deployed or is faulty, the PRE-SAFE Pulse Side Inoperative See Operator’s Manual display message appears.
Seat Belt Adjustment Function
Vehicles with PRE-SAFE®: after you have fastened the seat belt of the front seat, it may adjust itself against your body by pulling at the shoulder until somewhat tight. Do not hold the seat belt tightly while it is adjusting. This function is a reminder that all vehicle occupants must wear their seat belts correctly. You can activate and deactivate the seat belt adjustment function using the multimedia system. Activating/deactivating seat belt adjustment via the multimedia system

The function of the rear seat belt feeder
The seat belt feeder for the rear seat helps you fasten your seat belt. When the door is closed, the seat belt feeder extends.
The seat belt feeder retracts again in the following cases:
- The seat belt tongue is engaged in the seat belt buckle
- The seat belt tongue is not engaged in the seat belt buckle within a certain time
- The respective door is opened
If the vehicle is equipped with the MBUX Interior Assistant, the seat belt feeder can extend when you reach for the seat belt tongue.
- A certain speed is exceeded after pulling away
WARNING
Risk of injury or death due to an extended seat belt extender while the vehicle is in motion If the seat belt does not sit correctly on the body, it cannot perform its intended protective function.
- Always ensure that the seat belt extender is retracted while the vehicle is in motion.
If the seat belt feeder does not automatically retract, you must push it back by hand against the resistance to the stop before starting the vehicle. You can deactivate the seat belt feeder. Activate the child safety lock for the rear side windows. When installing a child restraint system on the rear seat, observe the vehicle-specific information.
Overview of the automatic measures after an accident
Depending on the type and severity of the accident, and depending on the vehicle’s equipment, the following measures may be implemented, for example:
- Automatic braking (post-collision brake)
- Activating the hazard warning lamps
- Triggering an automatic emergency call
- Switching off the engine
- Switching off the fuel supply
- Plug-in hybrid: switching off the hybrid system and high-voltage on-board electrical system R unlocking the vehicle doors
- Lowering the side windows
- Displaying the emergency guide on the central display
- Switching on the interior lighting
The function of the post-collision brake after an accident, Depending on the accident situation, the post-collision brake can minimize the severity of a further collision or even avoid it. If an accident is detected, the post-collision brake can initiate automatic braking. When the vehicle has come to a standstill, the electric parking brake is automatically applied.
The driver can cancel automatic braking by taking the following actions:
- Braking more strongly than automatic braking
- Fully depress the accelerator pedal with force
