R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise danger in
time, could cause an accident and injure
yourself and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
180 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This
corresponds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If Distronic detects a risk of collision with a
vehicle in front, an intermittent warning
tone sounds. In addition, the ldistance
warning lamp in the instrument cluster
lights up. Brake to avoid a collision. Cruise control lever You can operate Distronic and variable
Speedtronic with the cruise control lever.

Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.
Only use Speedtronic when you do not have
to accelerate suddenly to a speed higher
than the stored limit speed allows. You
could otherwise cause an accident.
You can only exceed the limit speed stored

R using the cruise control lever.
R by depressing the accelerator pedal
beyond the pressure point (kickdown). It is not possible to deactivate variable
Speedtronic by braking. G
Risk of injury
Variable Speedtronic brakes automatically
in order to avoid exceeding the set speed.
As it does so, the brake pedal is depressed.
Do not place your foot under the brake
pedal as it could become trapped.

the speed to any speed above 30 km/h while
the engine is running.
