Narrow vehicles
Distronic has not yet detected the vehicle in
front on the edge of the carriageway, because
of its relatively narrow width. The distance to
the vehicle in front will be too short.
Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
shift to a lower gear in good time or select
shift range 1, 2 or 3 in vehicles with automatic
transmission*. 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. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
G Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
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.
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. for driving on winter tyres

G Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.

The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic
With the cruise control lever, you can operate
cruise control, Distronic* and variable
Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
LIM indicator lamp off:
R
cruise control or Distronic* is selected
LIM indicator lamp lit:
R
variable Speedtronic is selected
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running.
