Retractable hardtop

The hardtop drive system was shut
down for safety reasons after multiple,
consecutive attempts to raise or lower
the hardtop. After about 10 minutes
you can open or close the retractable
hardtop.
Switch on the ignition (page 40).
Repeat the opening or closing
procedure.
If the retractable hardtop still does
not open, close, or lock properly,
have the retractable hardtop sys-
tem checked at an authorized
Mercedes-Benz Center.

There is a malfunction in the retract-
able hardtop system.
Contact an authorized
Mercedes-Benz Center.Wind screen

the driver and passenger when the retract-
able hardtop is lowered. It is stored in the
trunk.
Installing
Leave the wind screen folded and place
it on the roll bar.1Guide tabs
Slide the wind screen into the roll bar
until guide taps 1 on each side latch
underneath the roll bar.
Make sure the fastening straps do not
get caught.
Adjust the roll bar to a height
(
page 83) that allows you to reach
easily underneath it.
Warning!G
The wind screen can restrict the driver’s vi-
sion to the rear of the vehicle. To prevent a
possible accident when visibility is limited
(e.g. in darkness), the upper part of the wind
screen should be folded back.

Parktronic system* (Parking assist)
The Parktronic system is an electronic aid
with ultrasonic sensors. It is designed to
assist the driver during parking maneu-
vers. 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, or place the
gear selector lever in position D, R, or N.
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 remains 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 337).
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. Other-
wise you run the risk of causing injury.
!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.

Driving systems
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the
eighth distance segment illuminates, you
have reached the minimum distance.

Front area: An intermittent acoustic
warning will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second distance segment.
The signal is canceled when the gear
selector lever is placed in position P or
the parking brake is set.

Rear area: An intermittent acoustic
warning will sound when the first dis-
tance segment illuminates. This signal
quickens with each additional distance
segment lit. When the eighth distance
segment illuminates, the acoustic
warning becomes a constant signal.
The signal is canceled when the gear
selector lever is placed in positionD
orP or the parking brake is set.Switching the Parktronic system
on/off
You can switch off the Parktronic system
manually.

the indicator lamp in the Parktronic switch
comes on.
Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.

Parktronic switch comes on.
