Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond the
pressure point (kickdown), SPEEDTRONIC is
switched to passive mode. The

You can then exceed the stored speed. SPEED-
TRONIC is activated again if you:
drive slower than the stored speed without

The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to limit the
speed permanently to a value between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active, even

DISTRONIC PLUS
General notes
DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front. Vehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and prevents the brakes from overheat-
ing and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of
a collision, you will be warned visually and
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent a collision. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrument cluster. Brake immediately to
increase the distance to the vehicle driving in
front, or take evasive action, provided it is safe
to do so.
DISTRONIC PLUS operates in the range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes
G
WARNING
DISTRONIC PLUS does not react to:
people or animals
R
stationary obstacles on the road, e.g. stop-
R
ped or parked vehicles
oncoming and crossing traffic
R
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions.
