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

Function of Active Distance Assist DISTRONIC

Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles in front are detected, the set distance is maintained, if necessary, until the vehicle comes to a halt. The vehicle accelerates or brakes depending on the distance to the vehicle in front and the set speed. The speed and distance to the vehicle in front are set and saved using the steering wheel.

Available speed range:

• Vehicles without Driving Assistance Package: 15 mph (20 km/h) - 120 mph (200 km/h)
• Vehicles with Driving Assistance Package: 15 mph (20 km/h) - 130 mph (210 km/h)

Plug-in hybrid: the adjustable set speed can be reduced due to the selected drive program. Observe the relevant notes in the Supplement.

Other features of Active Distance Assist DISTRONIC:

• Adjusts the driving style depending on the selected drive program (fuel-saving, comfortable or dynamic)
• Initiates acceleration to the stored speed if the turn signal indicator is switched on to change to the overtaking lane
• Vehicles with Driving Assistance Package:
  • Reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles)
  • Takes one-sided overtaking restrictions into account on highways or on multi-lane roads with separate roadways (country-dependent)

Vehicles with Driving Assistance Package and Parking Package: if the vehicle has been braked to a standstill on multi-lane, separate roadways by Active Distance Assist DISTRONIC, it can automatically follow the vehicle in front driving off again within 30 seconds. If a critical situation is detected when driving off, a visual and acoustic warning is given indicating that the driver must now take control of the vehicle. The vehicle is not accelerated any further.

Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers.

Permanent status display of Active Distance Assist DISTRONIC

• (white): Active Distance Assist DISTRONIC selected, specified distance set
• (white vehicle, green speedometer): Active Distance Assist DISTRONIC active, specified distance set and vehicle detected
• (green): Active Distance Assist DISTRONIC active, specified distance set and vehicle detected
• : Route-based speed adaptation active.

The stored speed is shown along with the permanent status display and highlighted on the speedometer. When Active Distance Assist DISTRONIC is passive, the speed is grayed out.

On highways or high-speed major roads, the green vehicle symbol is displayed cyclically when the vehicle is ready to pull away.

If you depress the accelerator pedal beyond the setting of the Active Distance Assist DISTRONIC, the system is switched to passive mode. The   Suspended message appears in the multifunction display.

Display on the speedometer

The stored speed is highlighted on the speedometer. If the speed of the vehicle in front or the speed adjustment is less than the stored speed due to the route event ahead, the segments in the speedometer light up. Deactivation of Active Distance Assist DISTRONIC, as well as alterations to the speed due to manual or automatic adoption of the maximum permissible speed, are displayed in the control feedback of the multifunction display on a single line.
