Driving systems
The Parktronic system is an electronic aid
designed to assist the driver during
parking maneuvers. It visually and audibly
indicates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically
activated when you
ț switch on the ignition or start the
engine
and
ț release the parking brake
and
ț set the automatic transmission to
position D, R, or N
The Parktronic system deactivates at
vehicle speeds exceeding approximately
11 mph (18 km/h). At lower vehicle
speeds, the Parktronic system turns on
again.
The Parktronic system also deactivates
when you set the automatic transmission
to position P or depress the parking brake
pedal.
The Parktronic system monitors the
surroundings of your vehicle with six sen-
sors in the front bumper and four sensors
in the rear bumper.
1 Sensors 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 damaging the sensors, see
“Cleaning the Parktronic* system sensors”
(
page 408).
Warning! G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
!
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 damage to your
vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
working jackhammers, car wash or the air brakes
of trucks) may impair the operation of the
Parktronic system.
