114 Switching off the engine
G
Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking then takes
much more effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.
Do not switch off the engine while driving.
Vehicles with manual transmission X

Introduction to 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 floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. 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. Controls

The automatic transmission
changes gear automatically. All
forward gears are available.
One-touch gearshifting
When the selector lever is in position
D, you
can perform gearshifts yourself, even on vehi-
cles with automatic transmission.
X To shift up: briefly press the selector lever
to the right towards D+.
The automatic transmission shifts up to the
next gear, depending on the gearshift pro- gram selected. This also extends the shift
range.
X To shift down: briefly press the selector
lever to the left towards D–.
The automatic transmission shifts down to
the next gear, depending on the gear cur-
rently selected. This also restricts the shift
range.
i To prevent the engine from overrevving,
the automatic transmission does not shift
down if you push the selector lever towards
D– while driving at too high a speed.
X To derestrict the shift range: press and
hold the selector lever towards D+until D
is shown once more in the display.
The automatic transmission shifts from the
current shift range directly to D.
X To select the most effective shift
range: press and hold the selector lever to
the left towards D–.
The automatic transmission will shift to a
range which allows ideal acceleration and
deceleration. To do this, the automatic
transmission will shift down one or more
gears. Shift ranges When the selector lever is in position
D, it is
possible to restrict or derestrict the shift
range for the automatic transmission.
X Briefly press the selector lever to the right
towards D+or to the left towards D–.
The shift range selected is shown in the
display. The automatic transmission shifts
only as far as the selected gear.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving even if the shift range is restricted. Driving situation
è The braking effect of the engine can
be used in this position.Controls

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control, Distronic* 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 Vehicle level setting and AIRMATIC DC*,
which are used to adjust the vehicle's sus-
pension system
R 4*MATIC (permanent four-wheel drive), for
optimum traction
R Parktronic*, which assists you in parking
and manoeuvring
The ABS, BAS, adaptive brake lights, ESP ®
,
EBV (electronic brake-power distribution) and
ADAPTIVE BRAKE driving safety systems are
described in the "Driving safety systems" sec-
tion (Y page 58). Controls

tems 143Cruise 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 or towing a trailer, you must
shift to a lower gear in good time or select
shift range 1,2or 3in vehicles with automatic
transmission*. 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 accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to
fog, heavy rain or snow

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.
Vehicles with manual transmission:
R Always drive at adequate, but not exces-
sive, engine speeds.
R Change gear in good time.
R If possible, do not change down several
gears at a time. Selecting the current or last stored
speed G
Risk of accident

trol off message in the multi-function dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Distronic*
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 3. By doing so,you will make use
of the braking effect of the engine, which

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.
