Driving sys
tems 146 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 dangers 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 a preset distance to the vehicle in
front. 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
under braking or acceleration. The vehi-
cle could start to skid.
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 dangers 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.

Distronic and variable Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:

Make sure that you maintain the mini-
mum distance to the vehicle in front
required by law. Adjust the distance to the
vehicle in front if necessary.
Distance warning function Even if Distronic is deactivated, this function
warns you at speeds above 30 km/h if:
R
the distance to the vehicle in front is too
short for the speed you are driving at for
several seconds. The ldistance warn-
ing lamp in the instrument cluster then
lights up.
R you are approaching a vehicle in front at too
great a speed. You then hear an intermit-
tent warning tone, and the ldistance
warning lamp in the instrument cluster
lights up.
You must apply the brakes yourself in order
to maintain the correct distance to the vehicle
and to avoid a collision. G
Risk of accident
Be especially observant of traffic condi-
tions when the ldistance warning lamp
in the instrument cluster lights up or an
intermittent warning tone sounds. Brake or take evasive action as necessary.
i Distronic does not always clearly recog-
nise complex road and traffic conditions.
You may then receive a false distance warn-
ing tone or none at all.

231pressure, e.g. if the tyre is penetrated by a
foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres
R road conditions are wintry
R you are driving on sand or gravel
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load (in the
vehicle or on the roof) Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system

R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the operating con-
ditions concerned.
X Also observe the notes in the section on
tyre pressures (Y page 229). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set
the correct tyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident. X

G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes- Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every
5,000 km to 10,000 km depending on the
degree of tyre wear, provided that the vehicle
has the same size front and rear tyres. Do not
reverse the direction of tyre rotation.
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. The front
tyres typically wear more on the shoulders
and the rear tyres in the centre.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*. Operation

Certain display messages are accompanied
by a warning tone or a continuous tone.
The multi-function display shows high-priority
display messages in red. In the following
tables, these display messages are printed in

This means that you will not see information
about the driving situation, such as the speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
