Risk of accident
Observe the legal requirements of the
country in which you are currently driving
regarding the use of mobile phones in the
vehicle.
If it is permitted to use mobile phones while
the vehicle is in motion, you should only use
them when the road and traffic conditions
allow. You may otherwise be distracted
from the traffic conditions, cause an acci-
dent and injure yourself and others.

Driving sys
tems 148 Distronic*
i Distronic is only available for certain
countries.
Distronic regulates the speed and automati-
cally maintains the distance to the vehicle 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 1,2or 3in 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 over-
heating and wearing too quickly. G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are
fixed securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. 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 is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance to other vehicles,
the vehicle's speed and braking in good
time.
Distronic does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles
driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
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 a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and maintain the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not
activate, Distronic if it does not detect the
vehicle in front, or if it no longer detects it.
This is especially the case:
R before corners
R on filter lanes
R when changing to a lane with faster mov-
ing traffic
R in complex driving situations or where
the lanes are diverted, e.g. at motorway/
roadway construction sites
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip Controls
