sible for the distance to the vehicle in front, for
vehicle speed, braking in good time and for stay-
ing in your lane.
You are always responsible for maintaining con-
trol over your vehicle on downhill gradients. DSR
cannot always maintain the set speed, depend-
ing on the condition of the terrain and the tyres.
Select a set speed to suit the surrounding con-
ditions and also apply the brakes yourself, if
necessary.
You will find information on driving on unpaved
surfaces under "Driving off-road" (
Y
page 183).

You can only switch DSR on when you are driving
at 40 km/h or less. If the current speed is too
high, the display shows the

When DSR is activated and the vehicle acceler-
ates or brakes, the current speed is saved as the
set speed. This is only the case if you are not
driving faster than 18 km/h.
