MERCEDES-BENZ GL-Class 2016 X166 Owner's Manual

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:
Ryou are driving faster than 40 mph
(60 km/h)
RDISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC 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 dis-
tance between your vehicle and the vehicle in
front becomes too small.
iWhen you change lanes, DISTRONIC
PLUS monitors the left lane on left-hand-
drive vehicles or the right lane on right-
hand-drive vehicles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe 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 your vehicle 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 dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
The electric parking brake automatically
secures the vehicle if DISTRONIC PLUS is
activated and:
Rthe driver's door is open and the driver's
seat belt is unfastened.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
Ra system malfunction occurs.
Rthe power supply is not sufficient.
On steep uphill or downhill inclines or if there
is a malfunction, the transmission may also
automatically be shifted into position P.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.

Tips for driving with DISTRONIC PLUS
General notes
Pay particular attention inthe following traff ic
situations:
Rcornering, going into and coming out of a
bend
Rveh icles traveling on a different line
Rother veh icles changing lanes
Rnarrow veh icles
Robstructions and stationary vehicles
Rcrossing vehicles
In such situations, brake ifnecessary.
DI ST RONIC PLUS is then deactivated. Corn
ering, going into and coming out ofa
bend
The abilit y of DI STRONIC PLUS to detect veh i-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles traveling ona different line
DIST RONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the veh icle infrontwill be too short.
Other vehicles changing lanes
212Driving systems
Driving and parking

DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
Level control (vehicles with the
ON&OFFROAD package)
Important safety notes
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.
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.

(
Ypage 198).
GWARNING
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.
GWARNING
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.
GWARNING
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.
GWARNING
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.
RUtility 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.
RIn 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:
Rhighway/high-speed level for driving on
normal roads
Roff-road level 1 for driving on easily nego-
tiable off-road terrain
Roff-road level 2 for driving on normal off-
road terrain
Roff-road level 3 for freeing the vehicle in
particularly rough terrain at low speeds
only
The individual vehicle levels differ from high-
way level as follows:
Rhighway level: +/–0 in (+/–0 mm)
Rhigh-speed level: –0.6 in (–15 mm)
Roff-road level 1: + 1.2 in (+ 30 mm)
Roff-road level 2: + 2.3 in (+ 60 mm)
Roff-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.
