ground clearance MERCEDES-BENZ M-Class 2014 W166 Owner's Manual

G
WARNING
If the vehicle level is high, the vehicle center
of gravity is raised. This could cause the
vehicle to tip over more easily on uphill or
downhill gradients. There is arisk of an
accident.
Selec tthe lowest possible vehicle level.
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could get
into the brakes. This could result in a reduced
braking effect or in total brake failure and also
in increased wear and tear. The braking
characteristics change depending on the
material ingressing the brakes. Cleant he
brakes after driving off-road. If you detect a
reduced braking effect or grinding noises,
have the brake system checked in a qualified
specialist workshop as soon as possible.
Adapt your driving style to the different
braking characteristics.
Driving off-road increases the likelihood of
damage to the vehicle, which, in turn, can lead
to failure of the mechanical assembly or
systems. Adapt your driving style to suit the
terrain conditions. Drive carefully. Have
damage to the vehicle rectified immediately
at a qualified specialist workshop.
Do not switch to transmission position N
when driving off-road. You could lose control
of the vehicle if you attempt to brake using
the service brake. If the gradient is too steep,
drive backwards in reverse gear.
General notes Read this section carefully before driving your
vehicle off-road. Practice by driving over more
gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear shift operation
before driving through difficult terrain. The following driving systems are specially
adapted to off-road driving:
R
Off-road ABS (Y page 67)
R AIRMATIC package (vehicle level)
(Y page 207)
R DSR (Downhill Speed Regulation)
(Y page 246)
Observe the following notes:
R Stop the vehicle before starting to drive
along an off-road route.
R For vehicles with the AIRMATIC
package: select a vehicle level that is
suitable for the off-road terrain. To avoid
damaging the vehicle, make sure there is
always sufficient ground clearance.
R Check that items of luggage and loads are
stowed safely and are well secured
(Y page 337).
R Always keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR (Y page 246).
R Always keep the doors, tailgate, windows
and sliding sunroof closed while driving.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
R Drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R Drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Look out for obstacles, such as rocks,
holes, tree stumps and furrows.
R Check the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine.
R On sand, drive quickly to overcome the
rolling resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground. 188
Driving tipsDriving and parking

Driving on sand
Observe the following rules when driving on
sand:
R
vehicles wit hthe AIRMATIC package:
select a raised vehicle level.
R avoid high engine speeds.
R use the left-hand steering wheel paddle
shifter to shift to a lower gea rappropriate
to the terrain.
R drive quickly to overcome the rolling
resistance. Otherwise the vehicle's wheels
could become stuc kinloose ground.
R drive in the tracks of other vehicles if
possible. Make sure that:
-the tire ruts are not too deep.
- the sand is sufficiently firm.
- the ground clearance of the vehicle is
sufficient.
Tire ruts and gravel roads !
Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
R vehicles with the AIRMATIC package:
select a raised vehicle level.
R avoid high engine speeds.
R shift to a lower gear using the left-hand
steering wheel paddle shifter.
R drive slowly.
R where ruts are too deep, drive with the
wheels of one side on the center grassy
area, if possible.
Driving over obstacles !
Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers for guidance when driving over
large obstacles. The passenger should
always keep a safe distance from the vehicle when doing so in order to avoid
injury as a result of unexpected vehicle
movements. After driving off-road or over
obstacles, check the vehicle for possible
damage, especially to the underbody and
the components of the chassis.
Observe the following rules when driving over
tree stumps, large stones and other
obstacles:
R raise the vehicle level.
R avoid high engine speeds.
R shift to a lower gear using the left-hand
steering wheel paddle shifter.
R drive very slowly.
R drive straight over the center of obstacles. Traveling uphill
Approach/departure angle G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
R Observe the rules on off-road driving.
R Do not drive at an angle on slopes, inclines
or gradients, but instead follow the direct
line of fall. The maximum gradient-climbing
capability of your vehicle is 100%, which
corresponds to an approach/departure 190
Driving tipsDriving and parking

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.
The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the
vehicle level is lower; with an increase in
temperature, the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load
discrepancies while still parked. However, for
significant level changes, such as after the
vehicle has been stationary for a long period,
the engine must be on. For safety reasons,
the vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened, and it continues once the door has
been closed.
For information about driving off-road, see
(Y page 187). G
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,
and severe or fatal injury.
R In a rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt.
You and all vehicle occupants should
always wear your seat belts.

Driving systemsDriving and parking

When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
Vehicle level Level control adapts the vehicle level
automatically to the curren toperating and
driving situation .Level control ensures the
best possible suspension and constant
ground clearance, even with a laden vehicle.
This improves driving safety and fuel
consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system (Y page 207).
Due to the sportier suspension settings
compared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
In Comfort and Sport driving modes, after
locking the vehicle it lowers to the Sport+
level. When locking the vehicle at the raised
level, the vehicle does not lower.
The settings will remain stored after you
switch off the engine. When starting the
engine, the selected setting, e.g. AMG
adaptive suspension system Comfort, is
restored.
