Offset driving
A vehicle traveling in your lane but offset
from your direct line of travel may not be
detected by Distronic. There will be insuffi-
cient distance to the vehicle ahead.Lane changing
Distronic has not yet detected the vehicle
changing lanes. There will be insufficient
distance to the vehicle ahead.Narrow vehicles
Because of their narrow profile, the vehi-
cles traveling near the outer edges of the
lane have not yet been detected by Dis-
tronic. There will be insufficient distance to
the vehicles ahead.

220 Controls in detailDriving systemsActive Body Control (ABC)
The ABC system automatically selects the
optimum suspension tuning and ride
height for your vehicle.
Suspension tuning
The suspension tuning is set according to:

Your driving style


Road surface conditions


The vehicle loading


Your choice of suspension style,
“sporty” or “regular”, which you select
using the ABC switch.
The selected suspension style is stored
in memory, even after the SmartKey is
removed from the starter switch.The ABC switch with the indicator lamp is
located in the lower section of the center
console.

Vehicle level control
Your vehicle automatically adjusts its ride
height to:

reduce fuel consumption


increase vehicle safety
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


W it h inc re a sing s pe ed, ri de hei ght is re -
duced by up to approximately one inch
(25 mm).


With decreasing speed, the ride height
is again raised to the selected vehicle
level.Select the level 1 and 2 settings only when
required by current driving conditions.
Otherwise:


Fuel consumption may increase.


Handling may be impaired.iThese height adjustments are so small
that you may not notice any change.Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.

selected when the vehicle is stationary:
The switch and the indicator lamps are lo-
cated in the lower section of the center
console.
Briefly press switch3 to change from
one level setting to the next. At level 1,
indicator lamp2 is illuminated and at
level 2 both indicator lamps are illumi-
nated. When the vehicle is at level 2,
pressing the switch will return the vehi-
cle to normal level.

Driving systems
Parktronic* (Parking assist)
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition, re-
lease the parking brake, or place the gear
selector lever in Position D, R, or N. The
Parktronic system deactivates at speeds
above 11 mph (18 km/h). At lower speeds
the Parktronic system turns on again.
The Parktronic system also deactivates
when you place the gear selector lever in
Position P or depress the brake pedal.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumperWarning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic* system sensors”
(page 318).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. Other-
wise you run the risk of causing injury.

224 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors, see
“Cleaning the Parktronic system* sensors”
(page 318).

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches).
The Parktronic system will not detect
such objects at close range and dam-
age to your vehicle or the object may
result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes, car wash, or
jackhammers) may impair the opera-
tion of the Parktronic system.

Minimum 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 may no long-
er 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.
Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach warning indicator is divided into six
yellow and two red distance segments for
either side of the vehicle. The Parktronic
system is ready when the border around
the indicator is illuminated.

termines which warning indicators will be
activated.

226 Controls in detailDriving systemsAs your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the
eighth distance segment illuminates, you
have reached the minimum distance.

Front area: An intermittent acoustic
warning will sound as the first red dis-
tance segment illuminates and a con-
stant acoustic warning lasting a
maximum of two seconds will sound for
the second distance segment. The sig-
nal is canceled when the gear selector
lever is placed in position P or the park-
ing brake is set.


Rear area: An intermittent acoustic
warning will sound when the first dis-
tance segment illuminates. This signal
quickens with each additional distance
segment lit. When the eighth distance
segment illuminates, the acoustic
warning becomes a constant signal.
The signal is canceled when the gear
selector lever is placed in positionD
orP or the parking brake is set.Switching the Parktronic system
on/off
You can switch off the Parktronic system
manually.
The Parktronic switch is located in the low-
er part of the center console (
page 30).

Parktronic system malfunction
If only the red distance segments illumi-
nate and a warning sounds, there is a mal-
function in the Parktronic system. The
Parktronic system will automatically
switch off after 20 seconds and the indica-
tor lamp in the Parktronic switch comes
on.
Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.
If only the red distance segments illumi-
nate and no warning sounds, the Parktron-
ic system sensors are dirty or there is an
interference from other radio or ultrasonic
signals. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.

Switch off the ignition.

Check the Parktronic system operation
at another location to rule out interfer-
ence from outside radio or ultrasonic
signals.
