The last speed stored is cleared when you
switch off the engine.
DISTRONIC PLUS*
i
Distronic Plus is not available in all coun-
tries.
Distronic Plus regulates the speed and auto-
matically maintains the distance to the vehi-
cle in front. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1, 2 or 3 in good time. 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.
* optional
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.
G Risk of accident
DISTRONIC PLUS is only an aid designed to
assist driving. The driver is fully responsible
for the vehicle's distance from other vehicles,
®
the vehicle's speed and for braking in good
time.
DISTRONIC PLUS does not react to:
pedestrians
R
stationary obstacles on the road, e.g. stop-
R
ped or parked vehicles
oncoming and crossing traffic
R
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front.
G
Risk of accident
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
before corners

in filter lanes
