Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. Change into
al ower gear in good time on long and steep
downhill gradients. Take particular noteof
this when driving aladen vehicle. By doing so,
you will make use of the braking effect of the engine. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
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,f or vehicle
speed, for braking in good time, and for stay- ing in lane.
If there is achange of drivers, advise the new
driver of the speed stored.
You can set avariable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted i
The speed indicated in the speedometer
may differ slightly from the limit speed
stored.

WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is ar isk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you do not know the stored speed, store the
desired speed again. X

the pressure point (kickdown), SPEED-
TRONIC is switched to passive mode. The fol-
lowing message appears in the multifunction
display: SPEEDTRONIC passive SPEEDTRONIC passive.

Permanent SPEEDTRONIC You can use the on-board computer to limit
the speed permanently to
avalue between
160 km/h(e.g. for driving on winter tyres) and the maximum speed (Y page 292).
Shortly before the stored speed is reached, it appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variableS PEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal

General notes DISTRONIC PLUS regulates the speed and
automaticallyh
elps you maintain the dis-
tance to the vehicle detected in front.V ehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automaticallysot hat the set speed is not
exceeded.
Change into alower gear in good time on long

doing so, you will make use of the braking
effect of the engine. This relieves the load on Driving systems

DISTRONIC PLUS may not detect narrow
vehicles drivin ginfront,e.g. motorcycles, or

In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R sno worh eavy rain
