Your vehicle automatically adjusts its ride
height to
increase vehicle safety
reduce fuel consumption
The following vehicle chassis ride heights
can be selected:
Normal
Raised
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:
At a speed exceeding approximately
68 mph (110 km/h) with normal level
set or exceeding 75 mph (120 km/h)
with raised level set, the ride height is
reduced automatically. The table on
the next page provides an overview of
the vehicle levels.
With decreasing speed, the ride height
is again raised to the normal level.
!If you have selected the Comfort sus-
pension tuning, the vehicle lowers
slightly when you lock it within approx-
imately 60 seconds after switching off
the engine. When parking, make sure
that your vehicle cannot come into con-
tact with other objects, such as a curb,
while lowering. Your vehicle could oth-
erwise be damaged.iThe selected suspension style is stored
in memory, even after the SmartKey is
removed from the starter switch.

Rear sensorsMinimum distance
If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance might no
longer be indicated by the system.Warning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is integrated in the
rear trim.

Parktronic system will not detect such
objects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-

Warning!
G
The parcel net is intended for storing
light-weight items only.
Heavy objects, objects with sharp edges or
fragile objects may not be transported in the
parcel net. In an accident, during hard brak-
ing, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
The parcel net cannot protect transported
goods in the event of an accident.
Warning!
G
In order to help prevent spilling liquids on
vehicle occupants and/or vehicle equip-
ment, only use containers that fit into the
cup holder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or in an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
