2015 MERCEDES-BENZ GL-Class Owner's Manual

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 pos-
sible.
The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the vehi-
cle level is lower; with an increase in temper-
ature, the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load dis-
crepancies 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 199). 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 vehi- cle could rollover more easily, for example on
a bend. There is a risk of an accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style. G
WARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving char-
acteristics 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 per-
son wearing a seat belt.
You and all vehicle occupants should
always wear your seat belts.
Basic settings The extent to which the vehicle is raised or
lowered depends on the basic setting selec-
ted.
Select:
R highway/high-speed level for driving on
normal roads
R off-road level 1 for driving on easily nego-
tiable off-road terrain
R off-road level 2 for driving on normal off-
road terrain
R off-road level 3 for freeing the vehicle in
particularly rough terrain at low speeds

The individual vehicle levels differ from high-
way level as follows:
R highway level: +/–0 in (+/–0 mm)
R high-speed level: –0.6 in (–15 mm)
R off-road level 1: + 1.2 in (+ 30 mm)
R off-road level 2: + 2.3 in (+ 60 mm)
R off-road level 3: + 3.6 in (+ 90 mm)
Highway/high-speed level !
Make sure that there is enough ground
clearance when the vehicle is being low-
ered. It could otherwise hit the ground,
damaging the underbody. 0043

R Off-road level 2 at speeds up to 40 mph
(65 km/h)
R Off-road level 3 at speeds up to 12 mph
(20 km/ h)
If you are driving above 50 mph (80 km/h) or
drive between 40 mph (65 km/h) and 50 mph
(80 km/h) for longer than 20 seconds, off-
road level 2 will be canceled. The vehicle is
lowered to off-road level 1.
You will see a message in the multifunction

Depending on the vehicle's speed and the
ADS mode selected (Y page 220), the vehicle
is automatically lowered to highway or high-
speed level. You will see a message in the multifunction

Lowering. HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra-
dients or on slippery or loose surfaces. The HOLD function cannot hold the vehicle on
such surfaces.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away. 218

ADS (Adaptive Damping System)
General notes
ADS adapts the damping characteristics to
the current operating and driving situation.
This depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the SmartKey from the ignition lock.

In comfort mode, the dr iving characteristics
of your vehicle are more comfortable. There-
fore, select this mode if you favor a more
comfortable driving style. Select comfort
mode also when driving fast on straight roads,
e.g. on straight stretches of highway.
Active Curve System The Active Curve System uses active stabil-
izers to optimize both driving comfort and
vehicle agility. Depending on the ADS mode
selected (Y page 220), the Active Curve Sys-
tem also changes the setting.
If you select ADS comfort mode:
R rolling movement is reduced in the event of
changing surface undulations
R the roll angle when cornering is reduced
R the driving style is agile
If you select ADS sport mode:
R the roll angle is reduced significantly
R the driving style is even more agile 220

General notes
Further information about "Driving off-road"
(Y page 199).
Level control adapts the vehicle level auto-
matically to the current operating and driving situation. This results in reduced fuel con-
sumption and improved handling.
If you select ADS comfort mode (Y page 220),
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 220),
the vehicle skips highway level and lowers
directly to high-speed level depending on the
basic setting (Y page 222).
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 pos-
sible.
The vehicle level may change visibly if you

Basic settings (excluding AMG vehicles)
The extent to which the vehicle is raised or
lowered depends on the basic setting selec-
ted. Select raised level for off-road driving or
highway/high-speed level for normal roads.
The individual vehicle levels differ from high-
way level as follows:
R highway level: +/–0 in (+/–0 mm)
R high-speed level: –0.6 in (–15 mm)
R raised level: +2.3 in (+60 mm)
Basic settings for AMG vehicles
The extent to which the vehicle is raised or
lowered depends on the AMG adaptive sport
suspension setting selected. Select the
raised level for off-road driving or highway/
high-speed level for normal roads.
The raised level corresponds to a vehicle level
raised by 50 mm when compared with high-
way level in comfort mode.
Raised level Only select raised level if this is appropriate
for the road conditions. Otherwise, fuel con-
sumption may increase and handling may be
affected.
