Deactivating the HOLD function
The HOLD function is deactivated
automatically if:
Ryou accelerate and the transmission is in
positionDorR.
Ryou shift the transmission to positionP.
Ryou depress the brake pedal again with a
certain amount of pressure untilC
disappears from the multifunction display.
Ryou secure the vehicle using the electric
parking brake.
Ryou activate DISTRONIC PLUS.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
The electric parking brake automatically
secures the vehicle if the HOLD function is
activated and:
Rthe driver's door is open and the driver's
seat belt is unfastened.
Rthe engine is switched off.
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
be automatically shifted into positionP.
AIRMATIC package
General notes
AIRMATIC regulates the level of your vehicle.
As well as level control (Ypage 218), your
vehicle can be equipped with ADS (Adaptive
Damping System) (Ypage 217) and ACTIVE
CURVE SYSTEM (Ypage 218).
Observe the notes on driving with a trailer
(Ypage 264).
ADS (Adaptive Damping System)
General notes
ADS adapts the damping characteristics to
the current operating and driving situation.
This depends on:
Ryour driving style
Rthe road surface conditions
Rthe ADS setting
Rthe vehicle level setting
Your selection remains stored even if you
remove the SmartKey from the ignition lock.

clearance. You will otherwise damage the
vehicle.
!When you raise the vehicle in such a way
that not all wheels have contact with the
ground, remove the SmartKey from the
ignition lock.
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
person wearing a seat belt.
You and all vehicle occupants should
always wear your seat belts.
General notes
Further information about "Driving off-road"
(Ypage 197).
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
(Ypage 217), 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 (Ypage 217),
the vehicle skips highway level and lowers
directly to high-speed level depending on the
basic setting (Ypage 219).
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.
Basic settings (excluding AMG vehicles)
The extent to which the vehicle is raised or
lowered depends on the basic setting
selected. Select raised level for off-road
driving or highway/high-speed level for
normal roads.
The individual vehicle levels differ from
highway level as follows:
Rhighway level: +/–0 in (+/–0 mm)
Rhigh-speed level: –0.6 in (–15 mm)
Rraised 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
highway level in comfort mode.
Raised level
Only select raised level if this is appropriate
for the road conditions. Otherwise, fuel
consumption may increase and handling may
be affected.

If indicator lamps

PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to positionD,RorN
RRelease the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

PARKTRONIC does not take objects into
consideration that are:
Rbelow the detection range, e.g. people,
animals or objects
Rabove the detection range, e.g.
overhanging loads, truck overhangs or
loading ramps.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
parking.
You may also use PARKTRONIC
(Ypage 222).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active
Parking Assist parking procedure.
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
