tems 143Distronic*
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

R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
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 there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
180 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This
corresponds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If Distronic detects a risk of collision with a
vehicle in front, an intermittent warning
tone sounds. In addition, the ldistance
warning lamp in the instrument cluster
lights up. Brake to avoid a collision. Cruise control lever You can operate Distronic and variable
Speedtronic with the cruise control lever.

Tips for driving with Distronic The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic is then deacti-
vated.
Cornering, entering and exiting a bend The ability of Distronic to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or belatedly.
Vehicles travelling in a different line
Distronic may not detect vehicles travelling
on a different line. The distance to the vehicle
in front will be too short.
Other vehicles changing lane Distronic has not yet detected the vehicle
cutting in. The distance to this vehicle will be
too short.
Narrow vehicles Distronic has not yet detected the vehicle in
front on the edge of the carriageway, becauseControls

of its narrow width. The distance to the vehi-
cle in front will be too short. Speedtronic
Speedtronic brakes automatically so that you
do not exceed 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 overheating and wearing too quickly. If
you need additional braking, depress the
brake pedal repeatedly rather than continu-
ously. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. 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.
You can set a variable 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. for driving on winter tyres
(Y page 151) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.

may differ slightly from the limit speed

Select the raised level for very poor road con-

normal road conditions (Y page 154).
The vehicle is automatically lowered to high-
speed level when you:
