The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to perma-
nently limit the speed to a value between
160 km/h(e.g. for driving on winter tyres) and
the maximum design speed (
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active even
if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed, even
if you depress the accelerator pedal beyond the
pressure point (kickdown).
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.
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. By doing
so, you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
message in the
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.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
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.

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.

WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions.
In such cases, DISTRONIC PLUS may:

brake the vehicle
neither give a warning nor intervene
R
accelerate or brake unexpectedly

There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you.
