sis (approximate values):

between 0 mph (0 km/h) and 40 mph
(65 km/h) – none


between 40 mph (65 km/h) and
87 mph (140 km/h) – lowered pro-
gressively by approx. 0.4 in (11 mm).Raised level 1 (see table)

sis (approximate values):


between 0 mph (0 km/h) and 18 mph
(30 km/h) - raised by approx. 0.95 in
(24 mm)


between 18 mph (30 km/h) and
38 mph (60 km/h) - lowered progres-

gressively by additional approx. 0.55 in
(14 mm).
Parktronic system* (Parking assist)
iPressing the switch twice in quick suc-
cession will cause the vehicle to imme-
diately raise or lower according to the
starting level.
The selected vehicle level setting re-
mains stored in memory even if the en-
gine is turned off and restarted.
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
can be affected by dirty sensors, especially
at times of snow and ice, see “Cleaning the
Parktronic system sensors” (
page 259).
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.

Driving systems
Front sensors
Rear sensorsMinimum distance
If the system detects an obstacle in this
range, all the warning lamps light up and
you hear a warning signal. If the obstacle is
closer than the minimum distance, the ac-
tual distance might no longer be indicated
by the system.
Warning indicators
1Left front area warning indicator2Right front area warning indicator
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicators for the
front area are located above the left air
vents1 and center air vents2 in the dash-
board. The warning indicator for the rear
area is integrated in the rear trim.
Each warning indicator is divided into six
yellow and two red segments for either
side of the vehicle. The Parktronic system
is ready when the border around the indi-
cator is illuminated.Center

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Park-
tronic system will not detect such ob-
jects 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
Parktronic system.
