Parktronic system (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, and placed the
gear selector lever in positionD,R,orN.
The Parktronic system deactivates at
speeds over approximately 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
positionP or depress the parking 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 bumper
Range 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 373).
Warning!
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 373).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash or
the air brakes of trucks) can cause the sys-
tem 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. You
could otherwise injure them.

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 might no
longer be indicated by the system.Center

!
During parking maneuvers, pay special at-
tention 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 damage to your
vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
truck air brakes, car wash or jackhammers) 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 in the
rear trim.Front area warning indicator1Left side of the vehicle
2Right side of the vehicle
3Readiness indicatorsEach warning indicator is divided into five
yellow and two red segments for either
side of the vehicle. The Parktronic system
is operational when the yellow readiness
indicators3 are 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 seventh seg-
ment 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 2 seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in positionP or the
parking brake is activated.
Rear 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 2 seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in position D,P or
the parking brake is activated.
