General notes
DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. It brakes automatically in order to avoid exceeding the set speed.
On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must select shift range 1, 2 or 3 in good time. By doing so, you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
If a slower-moving vehicle is detected in front, DISTRONIC PLUS causes your vehicle to brake and maintain the preset distance to the vehicle in front.
If there is no vehicle driving in front of you, DISTRONIC PLUS functions like cruise control at a speed range between 20 mph (Canada: 30 km/h) and 120 mph (Canada: 200 km/h). If a vehicle is driving in front of you, it functions at a speed range between 0 mph (0 km/h) and 120 mph (Canada: 200 km/h).
Do not use DISTRONIC PLUS while driving on roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities. You can refer to the applicable section in the Operator's Manual if there are any questions concerning this.
