By depressing the gas pedal while the vehicle is standing still and ACC is active, the vehicle will ac-celerate. Once you take your foot off the pedal, ACC will automatically resume the stored speed and regulate the set distance.
ACC will not automatically accelerate if the vehicle ahead accelerates.
Distance (time interval) to the vehicle ahead and driving profiles
The distance the ACC maintains to the vehicle traveling ahead is determined by time intervals. A time distance to the vehicle traveling ahead is maintained. This results in a speed-dependent distance. The
higher the speed, the larger the distance in feet/meters ⇒ .
The distance can be set at 4 different levels:
Distance Time distance at 65 mph
(105 km/h)
Very small about 1,0 Seconds
Small about 1,3 Seconds
Medium about 1,8 Seconds
Large about 2,5 Seconds
Besides changing the time distance, the acceleration characteristics can be changed, by choosing on of the following driving profiles:
x Comfort
x Normal
x Sport
The distance intervals can be set by pushing the slider switch on the lever ⇒ fig. 273. The driving profile can only be set in the infotainment system .
Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.
Setting the distance and selecting a driving profile
In order to show the currently selected distance in the instrument cluster display, briefly tap the sliding
switch on the lever ⇒ fig. 273.

DANGER
Following other vehicles too closely increases the risk of collisions and serious personal injury or even death.
x Always obey applicable traffic laws when setting the distance to the vehicles ahead in traffic.
x Setting short distances to the traffic ahead reduces the time and distance available to bring your vehicle to a safe stop and makes it even more necessary to pay close attention or traffic.
x Always use good judgment and select a safe following distance for the traffic, road and weather conditions.
x Never use Adaptive Cruise Control on narrow or winding roads or under poor road condi-tions (snow, ice, streets covered with standing water or gravel, for example) or when visibility is poor, especially when it is foggy.
x Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.
