Driving systems
Parktronic system* (Parking assist)
The Parktronic system assists the driver
during parking maneuvers. It visually and
audibly indicates the distance between the
vehicle and an obstacle.
With the ignition on, the Parktronic system
engages automatically at speeds up to ap-
proximately 10 mph (15 km / h) and deac-
tivates during higher speeds.Parktronic system monitors your vehicle’s
environment by means of six sensors in
the front bumper and four sensors in the
rear bumper.

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 rests
always with the driver.
Make sure that no persons or animals are lo-
cated in the area in which your are maneu-
vering. They could otherwise be injured.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected 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. For notes
on cleaning the Parktronic system sensors
(page 237).
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.

154 Controls in detailDriving systemsMonitoring reach of sensors
The sensors must be free of dirt, ice and
snow or they will be unable to function
properly. Clean the sensors regularly with-
out scratching or damaging them.Front sensors
Rear sensorsMinimum distance
When an obstacle is located in this area, all
warning displays will light up and a warning
tone will sound. If the vehicle moves closer
than the minimum distance to an object,
the distance may no longer be displayed.

iDuring parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Parktro-
nic system will not detect such objects
at close range and damage to your ve-
hicle 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.
