BAS PLUS (Brake Assist System PLUS)

Mercedes-Benz GL-Class / Mercedes-Benz GL-Class Owners Manual / Safety / Driving safety systems / BAS PLUS (Brake Assist System PLUS)

Observe the "Important safety notes" section  .

BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS.

For BAS PLUS to assist you when driving, the radar sensor system must be:

Х activated  Х operational

With the help of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time.

If the radar sensor system is malfunctioning, BAS PLUS will not be available. The brake system is still available with complete brake boosting effect and BAS.

BAS PLUS provides braking assistance in hazardous situations at speeds greater than 4 mph (7 km/h).

At speeds of up to approximately 40 mph (70 km/h), BAS PLUS can also detect stationary objects. Examples of stationary objects are stopped or parked vehicles.

To prevent a front-end collision, BAS PLUS calculates the brake force necessary if:

Х you approach an obstacle, and Х BAS PLUS has detected a risk of collision

At a speed less than 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possible moment.

At a speed greater than 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traffic situation.

If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFEЃ) are activated simultaneously.

Keep the brake pedal depressed until the emergency braking situation is over.

ABS prevents the wheels from locking.

BAS PLUS is deactivated and the brakes function as usual, if:
Х you release the brake pedal.

Х there is no longer any danger of a rear-end collision.

Х no obstacle is detected in front of your vehicle.

If you have activated DSR  , BAS PLUS is likewise deactivated.

WARNING

BAS PLUS cannot always clearly identify objects and complex traffic situations. BAS PLUS cannot intervene in these cases. There is a risk of an accident.

Always pay careful attention to the traffic situation and be ready to brake.

In particular, the detection of obstacles can be impaired if:
Х there is dirt on the sensors or anything else covering the sensors.

Х snow or heavy rain Х interference by other radar sources Х there are strong radar reflections, for example in parking garages Х a narrow vehicle traveling in front, e.g. a motorbike
Х a vehicle traveling in front on a different line relative to the center of your vehicle

WARNING

BAS PLUS does not react: Х to people or animals Х to oncoming vehicles Х to crossing traffic Х when cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident.

Always pay careful attention to the traffic situation and be ready to brake.

Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle.
