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

notes" Observe the "Important safety notes" section.

At speeds above approximately 20 mph (30 km/h), BAS PLUS assists you when braking in hazardous situations and uses the radar sensor system to evaluate the traffic conditions.

the FCC This device has been approved by the FCC as a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way.
Any unauthorized modification to this device could void the user's authority to operate the equipment.

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.

At speeds up to approximately 40 mph (70 km/h), BAS PLUS can also detect stationary obstacles, for example stopped or parked vehicles.

Should you approach an obstacle and BAS PLUS has detected a risk of collision, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. Should you apply the brakes forcefully, BAS PLUS can automatically increase the braking force to a level suitable for the traffic conditions.

until the Keep the brake pedal depressed until the emergency braking situation is over.
ABS prevents the wheels from locking.

The brakes will work normally again if:
• you release the brake pedal.
• there is no longer any danger of a rear-end collision.
• no obstacle is detected in front of your vehicle.

BAS PLUS is then deactivated.

For BAS PLUS to assist you when driving, the radar sensor system must be switched on and operational, see "Radar sensor system" in the index.

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 there is:
• dirt on the sensors or anything else covering the sensors
• snow or heavy rain
• interference by other radar sources
• the possibility of strong radar reflections, for example in parking garages
• a narrow vehicle traveling in front, e.g. a motorbike
• a vehicle traveling in front on a different line

WARNING
BAS PLUS does not react:
• to people or animals
• to oncoming vehicles
• to crossing traffic
• in curves
As a result, BAS PLUS cannot intervene in 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.

If BAS PLUS is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS.
