WARNING
The vehicle is slightly lowered if you:
R have selected the SPORT suspension tun-
ing at normal level and
R switch off the engine
Persons in the vicinity of the wheel arch or the underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of thewheel arch or the underbody when you switch
off the engine.
! When the engine is switched off, the vehi-
cle is lowered if SPORT suspension tuning
has been selected at the normal level. The
vehicle is automatically lowered by approx- imately 10 mm. Make sure when parking
that you position your vehicle so that it
does not make contact with the kerb as the
vehicle is lowered. Your vehicle could oth-
erwise be damaged.

Make sure that the engine is running or that
it has been switched off by the ECO start/
stop function.
X Make sure that a speed of 120 km/h is not
exceeded.

speed over 80 km/h.
Suspension setting General notes
The electronically controlled ABC suspension
system features improved driving dynamics
and ride comfort.
The ABC suspension system is tuned individ-
ually to each wheel and depends on:
R the road surface condition, e.g. bumps
R the vehicle load
R your individual selection of the sporty or
comfortable button
Your selection remains stored even if you
remove the key from the ignition lock. 200

Vehicle level General notes
In order to reduce fuel consumption and
improve the driving dynamics, the vehicle is
lowered as its speed increases. In the SPORT
suspension setting, it is lowered by up to
13 mm, with COMFORT by up to 5 mm. As the
speed is reduced, the vehicle is raised to the set vehicle height.
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Important safety notes
The vehicle is slightly lowered when the
engine is switched off. G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury. When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate
vicinity of the wheel arches.
! If you have selected the normal level and
switched the engine off, the vehicle is low-
ered. The vehicle is automatically lowered
by approximately 10 mm. Make sure when
parking that you position your vehicle so
that it does not make contact with the kerb
as the vehicle is lowered. Your vehicle
could otherwise be damaged.

sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 205) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Parking Important safety notes
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods vehicles. In some circumstances, Active Park- ing Assist may therefore guide you into the
parking space too early. G
WARNING
If objects are located above the detection
range, Active Parking Assist may start to steer into the parking space too soon. As a result,
you could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop the vehicle and switch Active
Parking Assist off. G
WARNING
Active Parking Assist merely aids you by inter- vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself.
Always apply the brakes yourself when park-
ing and manoeuvring.
Detecting parking spaces Example: detected parking space
Active Parking Assist is activated automati-
cally when driving forwards. The system is
operational at speeds of up to approximately 35 km/h. While in operation, the system inde- pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h, you will see
parking symbol ;as a status indicator in the
instrument cluster. When a parking space has
been detected, an arrow towards the right =
or the left :also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand- ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. If you wish to park in
a space on the driver's side, the turn signal on 208

Securing the vehicle on level ground
X On level ground: place chocks or other
suitable items under the front and rear of
the wheel that is diagonally opposite the
wheel you wish to change. Securing the vehicle on slight downhill gradients
X On light downhill gradients: place
chocks or other suitable items in front of
the wheels of the front and rear axle.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle. The following must be observed when raising
the vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suitable for per-
forming maintenance work under the vehi- cle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and positioning wheel chocks. Never
release the parking brake while the vehicle
is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat, load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. a rubber mat.
R do not use wooden blocks or similar
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. Changing a wheel
