Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. 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. This could cause you
to lose control of your vehicle and cause an
accident. Automatic transmission
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.

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

automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Storing the current speed or calling up
the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others. 228

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 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

rent speed if it is activated for the first time,
or adjusts the vehicle's speed to the last
speed stored.
Setting the specified minimum dis-
tance for Distronic You can set the specified minimum distance
for Distronic by varying the time span
between one and two seconds. This time span
determines the distance that Distronic should
maintain from the vehicle in front, depending
on the road speed. You can read this distance
in the multi-function display (Y page 233). X
To increase: turn thumbwheel ;towards
=.
Distronic then maintains a greater distance
between your vehicle and the vehicle in
front.
X To decrease: turn thumbwheel ;
towards :.
Distronic then maintains a shorter distance
between your vehicle and the vehicle in
front.
i Make sure that you maintain the mini-
mum distance to the vehicle in front
required by law. Adjust the distance to the
