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
and release the parking brake. The Park-
tronic system deactivates at speeds over
approximately 11 mph (18 km/h). At low-
er speeds the Parktronic system turns on
again.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 308).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

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.Front sensors

Minimum distance
If the system encounters an obstacle in
this range, all the warning lamps come on
and you hear a warning signal. If the obsta-
cle is closer than the minimum distance,
the actual distance may no longer be indi-
cated by the system.

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Park-
tronic system will not detect such ob-
jects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Parktronic 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 be-
tween the rear backrests.Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach warning indicator is divided into six
yellow and two red segments for either
side of the vehicle. The Parktronic system
is ready when the border around the indi-
cator is illuminated.
The position of the gear selector lever de-
termines which warning indicators will be
activated.As your vehicle approaches an object, one
or more segments will come on, depending
on the distance. When the eighth segment
comes on, you have reached the minimum
distance.
Front area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of three
seconds will sound for the second red
segment. The signal is canceled when
the gear selector lever is placed in
positionP.
Rear area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of three
seconds will sound for the second red
segment. The signal is canceled when
the gear selector lever is placed in po-
sition D orP.
