2013 MERCEDES-BENZ M-Class warning

Activating at the current speed/last
store dspeed G
WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates or decelerates. If you do not know
the stored speed, the vehicle could accelerate
or brake unexpectedly. There is a ris kofan
accident.
Pay attention to the road and traffic
conditions before calling up the stored speed.
If you do no tknow the stored speed, store the
desired speed again. X
Briefly pull the cruise control lever towards
you 0002.
X Remove your foo tfrom the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is
stored. Otherwise, it sets the vehicle cruise
speed to the previously stored value. Driving with DISTRONIC PLUS Pulling away and driving
X
If the vehicle in front pulls away: remove
yourf oot from the brake pedal.
X Briefly pull the cruise control lever towards
you 0003or press it up 0002or down 001F.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in front has slowed down, it brakes your
vehicle. In this way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up
to the speed you have stored.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40mph
(60 km/h)
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front 198
Driving systemsDriving and parking

R
you switch on the appropriate tur nsignal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, your vehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
Vehicles with COMAND Example: traffic circle
i
The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic
situations. This is the case if, while following
a vehicle, DISTRONIC PLUS is active and you:
R approach or drive through a traffic circle
R approach a T-intersection
R tur no ff at a highway exit
Even if the vehicle in front leaves the
detection range, DISTRONIC PLUS
temporarily maintains the current driving
speed and does not accelerate. This is based
on the current map data in the navigation
system.
The current speed is maintained:
R approximately 10 seconds before the
traffic circle/T intersection and approximately 1.5 seconds whe
ndriving on
a traffic circle.
R approximately 12 seconds before reaching
a highway exit and approximately
4s econds after the highway exit.
Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a
vehicle occupan torfrom outside the
vehicle.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
If DISTRONIC PLUS detects that the vehicle
in front is stopping, it brakes yourv ehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
Depending on the specified minimum
distance, your vehicle will come to a standstill
at a sufficien tdistance behind the vehicle in
front .The specified minimum distance is set
using the control on the cruise control lever. Driving systems

WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle .There is a risk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered. G
WARNING
When you drive with the vehicle raised, the
driving characteristics could be impaired by
the vehicle's raised center of gravity. The
vehicle could rollover more easily, for
example on a bend. There is a risk of an
accident.
Always select as low a vehicle level as
possible and adjust your driving style. G
WARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving characteristics can be significantly impaired.
You could also exceed the permissible vehicle
height if the chassis is raised. There is a risk
of an accident.
Adjust the vehicle level before pulling away.
G
WARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure there is always sufficient ground
clearance. You will otherwise damage the
vehicle.
R Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,

General notes
Further information about "Driving off-road"
(Y page 187).
Level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
If you select ADS comfort mode
(Y page 209), the vehicle is lowered to high-
speed level as the speed increases. As the
vehicle speed decreases, the vehicle is raised
back up to highway level.
If you select ADS sport mode (Y page 209),
the vehicle skips highway level and lowers
directly to high-speed level depending on the
basic setting (Y page 211).
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as
possible. 210
