Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.

SPEEDTRONIC
General notes
SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer. For vehi-
cles with automatic transmission, you need to
have selected manual shift drive program M
( page 177). By doing so, you will make use
Y
of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
You can set a variable or permanent limit
speed:
variable for speed limits, e.g. in built-up
R
areas
permanent for long-term speed restric-
R
tions, e.g. when driving with winter tyres
fitted (

The speed indicated in the speedometer

stored.
Important safety notes
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an
accident nor override the laws of physics.
SPEEDTRONIC cannot take into account
road, weather or traffic conditions. SPEED-
TRONIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
Cruise con‐ Cruise con‐
speed, for braking in good time, and for stay-
ing in lane.
If there is a change of drivers, advise the new
driver of the speed stored.
