Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes.
On long downhill gradients, the automatic
transmission shifts down as a further meas-
ure.

Distronic*
Distronic regulates the speed and automati-
cally maintains the distance to the vehicle 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, you must select shift range 1, 2 or 3.
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.
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid.
G
Risk of accident
Distronic is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance from other vehi-
cles, the vehicle's speed and braking in
good time.
