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.

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 326).
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 326).

!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.
