Mercedes-Benz GLC : Driving and driving safety systems / Active Distance Assist DISTRONIC - System limits

The system may be impaired or may not function in the following situations, for example:

• In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying ambient light.
• If there is swirling dust, e.g. when driving offroad or on sandy surfaces.
• The windshield in the area of the camera is dirty, fogged up, damaged or covered.
• If the radar sensors are dirty or covered.
• In parking garages or on roads with steep uphill or downhill gradients.
• If there are narrow vehicles in front, such as bicycles or motorcycles.

In addition, on slippery roads, braking or accelerating can cause one or several wheels to lose traction and the vehicle could then skid.

Do not use Active Distance Assist DISTRONIC in these situations.

WARNING Risk of accident from acceleration or braking by Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC may accelerate or brake in the following cases, for example:

• If the vehicle pulls away using Active Distance Assist DISTRONIC.
• If the stored speed is called up and is considerably faster or slower than the currently driven speed.
• If Active Distance Assist DISTRONIC no longer detects a vehicle in front or does not react to relevant objects.

Always carefully observe the traffic conditions and be ready to brake at all times.

Take into account the traffic situation before calling up the stored speed.

WARNING Risk of accident due to insufficient deceleration by Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC brakes your vehicle with up to 50% of the possible deceleration. If this deceleration is not sufficient, Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning.

Adjust your speed and maintain a suitable distance from the vehicle in front.

Brake the vehicle yourself and/or take evasive action.

WARNING Risk of accident if detection function of Active Distance Assist DISTRONIC is impaired

Active Distance Assist DISTRONIC does not react or has a limited reaction:

• when driving on a different lane or when changing lanes
• to pedestrians, animals, bicycles or stationary vehicles, or unexpected obstacles
• to complex traffic conditions
• to oncoming vehicles and crossing traffic

As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in such situations.

Always observe the traffic conditions carefully and react accordingly.
