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

X
Briefly pull the cruise control lever towards
you =.
X Remove your foot from the accelerator
pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously
stored speed.
Setting a speed X
Press the cruise control lever to the pres-
sure point, up :for a higher speed or
down ?for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
Making fine adjustments in 1 km/h
increments X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down ?for a lower speed.
The last speed stored is increased or
reduced.
Making adjustments in 10 km/h incre-
ments X
Briefly press the cruise control lever
beyond the pressure point, up :for a
higher speed or down ?for a lower speed.
The last speed stored is increased or
reduced. Deactivating cruise control There are several ways to deactivate cruise
control:
X
Briefly press the cruise control lever for-
wards B.
or
X Brake.
or
X Briefly press the cruise control lever in the
direction of arrow A.
Variable Speedtronic is selected. LIM indi-
cator lamp ;in the cruise control lever
lights up.
Cruise control is automatically deactivated if:
R you engage the electric parking brake
R you drive at less than 30 km/h
R ESP ®
intervenes or you deactivate ESP ®
R you shift the automatic transmission to N
while driving
If cruise control is deactivated, you will hear
a warning tone. You will see the Cruise
control off message in the multi-function
display for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. 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, 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. Driving systems

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, 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
Risk of accident
The brake pedal is retracted when Distronic
Plus 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 Plus 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 Plus 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 Plus may not detect narrow vehicles
driving in front, e.g. motorcycles, or vehicles
driving on a different line. Therefore, always
pay attention to traffic conditions even when
Distronic Plus is activated. Otherwise, you
may fail to recognise dangers in time, could
cause an accident and injure yourself and oth-
ers.
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. Driving systems

Distronic Plus may not detect vehicles trav-
elling on a different line. The distance to the
vehicle in front will be too short.
Other vehicles changing lane Distronic Plus has not detected the vehicle
cutting in yet. The distance to this vehicle will
be too short.
Narrow vehicles Distronic Plus does not detect 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. Obstructions and stationary vehicles Distronic Plus does not brake for obstacles or
stationary vehicles. For example, if the detec-
ted vehicle turns a corner and reveals an
obstacle or stationary vehicle, Distronic Plus
will not brake for these.
Crossing vehicles Distronic Plus may detect vehicles that are
crossing your lane by mistake. Activating Dis-
tronic Plus at traffic lights with crossing traf-
fic, for example, could cause your vehicle to
pull away unintentionally.
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, you must select shift range
1, 2or 3in good time. By doing so, you will
