page 252) goes out.The following applies additionally when
towing a trailer:


The vehicle is lowered to the highway
level when it reaches a speed of 5 mph
(8 km/h).


The high-speed level is not available.


The restrictions that apply to towing
also apply when using accessories that
are connected to the trailer power
socket, such as an accessory bicycle

iThe vehicle is lowered to the highway
level if:

the vehicle speed is above 55 mph
(88 km/h)


the speed stays between 40 mph
(64km/h) and 55mph (88km/h)
for approximately 20 seconds
iDepending on the ADS setting
(page 249), the vehicle will be low-
ered to the high-speed level when trav-
eling at higher speeds. At speeds below
40 mph (64 km/h) at the latest, it will
be returned to the highway level.
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 377).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.


255 Controls in detail
Driving systems
The Parktronic system is an electronic
parking aid and 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 switch on the ignition,
release the parking brake, and set the
automatic transmission toD,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 set the automatic transmission
toP 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 damaging the sensors, see
“Cleaning the Parktronic* system sensors”
(
page 377).
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

256 Controls in detailDriving systemsFront sensors
Rear sensorsMinimum distance
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 may no long-
er be indicated by the 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 located in the rear
passenger compartment in the roof dome.

3Readiness indicators
Each warning indicator is divided into five
yellow and two red segments for either
side of the vehicle. The Parktronic system
is operational when the readiness
indicators3 are illuminated.
The position of the automatic transmission
determines which warning indicator will be
activated.

!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 sourc-
es (e.g. working jackhammers, car
wash or the air brakes of trucks) may
impair the operation of the Parktronic
system.
