Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control, Distronic*, Distronic Plus*
and Speedtronic, which are used to control
the speed of the vehicle
R HOLD, which makes pulling away easier,
particularly on steep uphill gradients
R AIRMATIC* and Active Body Control (ABC),
which is used to adjust the vehicle’s sus-
pension system
R 4MATIC* (permanent four-wheel drive), for
optimum traction
R PARKTRONIC and Park Assist*, which
assist you when parking
R reversing camera*, which assists you when
parking
R Night View Assist*, which assists you when
driving in the dark
R Parking Guidance*, which assists you when
looking for a parking space and assists you
when parking
R Blind Spot Assist*, which assists you when
changing lanes
The ABS, BAS, BAS PLUS*, adaptive brake
lights, ESP ®
, EBV, ADAPTIVE BRAKE, distance
warning function* and PRE-SAFE ®
Brake*
driving systems are described in the "Driving
safety systems" section (Y page 48).Cruise control
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and steep downhill gradients, especially if the
vehicle is laden, 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. 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever. Driving systems

G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.

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

Risk of accident
Distronic is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance from other vehicles,
the vehicle's speed and for 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 driv-
ing in front, e.g. motorcycles, or vehicles driv-
ing on a different line. Therefore, always pay
attention to traffic conditions even when Dis-
tronic is activated. Otherwise, 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 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 acti-
vate, 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 in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
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 when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Otherwise,
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
200 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This cor-
responds to approximately 20% of your vehi-
cle's maximum braking power. You must also
apply the brakes yourself if this braking power
is not sufficient. 230

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, because
of its narrow width. The distance to the vehi-
cle in front will be too short. 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, 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. G

tional braking, depress the brake pedal
repeatedly rather than continuously.
G
Risk of accident
Never depress the brake pedal continuously
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 245) 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.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever, you can operate
cruise control or Distronic*/Distronic Plus*

Blind Spot Assist uses a radar sensor system
to monitor the area on both sides of your
vehicle. It supports you when you change
lanes at speeds above 30 km/h. In each case,
a warning lamp appears in the exterior mirror
as soon as a vehicle is detected in the area
monitored. When you switch on the corre-
sponding turn signal prior to changing lanes,
you receive an optical and acoustic collision
warning. Blind Spot Assist uses two sensors
in the front bumper and four sensors in the
rear bumper. G
Risk of accident
Blind Spot Assist is only an aid and may not
detect all vehicles. Blind Spot Assist does not
relieve you of the responsibility of paying
attention.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: you must deactivate the radar sensor 260

Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will no
longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the steering wheel so that you can see
the tyre tread more easily.
You could otherwise lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The applicable value for the spare
wheel*/"Minispare" emergency spare
wheel* is stated on the spare wheel and in
the technical data section. G
Risk of accident
Tyre pressure that is either too high or too low
has a negative effect on the vehicle’s driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres- sure can be checked in the on-board com-
puter. G
Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Risk of accident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz has been fitted on the
tyre valve.
Tyre pressures that are too low have a nega-
tive effect on vehicle safety, which could lead
to your causing an accident.
If possible, you should only correct tyre pres-
sures when the tyres are cold. Depending on
the ambient temperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R increase the likelihood of tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and 298

will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel*. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning
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. G
Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, 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 carefully. Do
not make any sudden steering movements
when doing so.
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 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
if you have:
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 ( Ypage 298). 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
vehicle instability when driving, thus increas-
ing the risk of an accident.
