Rear Park Assist*
The Rear Park Assist system is an electron-
ic aid designed to assist the driver during
parking maneuvers. It visually and audibly
indicates the relative distance between the
rear of the vehicle and an obstacle.
The Rear Park Assist system is automati-
cally activated when you switch on the ig-
nition and shift the gear selector lever to
positionR.The Rear Park Assist system monitors the
rear area of your vehicle by means of four
sensors in the rear bumper.
1SensorsWarning!
G
Rear Park Assist (rear Parktronic) is a sup-
plemental 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
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Rear Park
Assist can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Rear Park Assist sensors”
(page 234).
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 that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.

166 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 them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps light up
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 Rear
Park Assist system will not detect such
objects 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
Rear Park Assist system.
