Warning!
G
Before operating the retractable hardtop,
make sure there is no danger of anyone
being injured by the moving parts (retract-
able roof, roof frame, and trunk lid) due to in-
attention.
Hands must never be placed near the roof
frame, upper windshield area, hardtop, shelf
behind roll bars, or trunk lid while the re-
tractable hardtop is being raised or lowered.
Serious personal injury may occur.

Retractable hardtop


The hardtop drive system has shut it-
self down. For safety reasons, no more
than five consecutive attempts may be
made to raise or lower the hardtop.
After about 10 minutes you may
again attempt to open or close the
retractable hardtop.
If the indicator lamp in the retractable
hardtop switch flashes when starting off or
while driving and you hear a warning sound
for a maximum of 10 seconds, the retract-
able hardtop is not locked.

Properly lock the retractable hardtop
(page 198) before continuing to
drive.
If the indicator lamp continues to flash af-
ter you have carried out the above actions,
there is a malfunction.

Have the retractable hardtop system
checked at an authorized
Mercedes-Benz Center.Indicator lamp in the retractable hard-
top switch is on when vehicle is stopped
If the indicator lamp in the retractable
hardtop switch comes on while the vehicle
is standing still and the switch was not ac-
tivated, then the retractable hardtop is not
locked.

There is a malfunction in the retractable
hardtop system.

Notify an authorized Mercedes-Benz
Center.Wind screen
The wind screen deflects drafts away from
the driver and passenger when the hardtop
is lowered. It is stored in a separate stor-
age bag.
Installing

Leave the wind screen folded and place
it on the roll bar.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.

204 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed


ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics


Parktronic*, which assists the driver
during parking maneuvers
For information on the BAS, ABS, and
ESP®, see “Driving safety systems”
(
page 82).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. Cruise control can be set
at any speed above 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 22).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must remain at
all times responsible for the vehicle speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

206 Controls in detailDriving systems
Setting a higher speed
Lift the cruise control in direction of
arrow1 (
page 205) and hold it
there until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control in direction
of arrow2 (
page 205) and hold it
there until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.
iThe cruise control switches off auto-
matically if

you step on the brake pedal


you depress the parking brake
pedal
The cruise control also switches off au-
tomatically when


the vehicle speed is below
20 mph (30 km/h) (
page 204)


the ESP
® is in operation or switched
off with the ESP
® switch
(

you move the gear selector lever to
positionN while driving
An acoustic warning sounds and the
message
CC Off
appears in the multi-
function display for approximately
5 seconds.
iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.iThe last stored speed is canceled when
you turn off the engine.!Moving the gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).
iWhen you use the cruise control lever
to decelerate, the brake system will au-
tomatically brake the vehicle if the en-
gine’s braking power does not brake
the vehicle sufficiently.

Driving systems
Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster
Briefly tip the cruise control lever in
direction of arrow1 (
page 205).
Slower

Briefly tip the cruise control lever in
direction of arrow2 (
page 205).Setting to last stored speed
(“Resume” function)

Briefly pull the cruise control lever in di-
rection of arrow4 (
page 205).
The cruise control will resume the last
set speed.

Remove your foot from the accelerator
pedal.
The selected speed appears in the mul-
tifunction display.
Distronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
during travel on expressways and other
major roads.

If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at a preset
distance.


If there is no vehicle directly ahead of
you, Distronic will function in the same
way as cruise control (
page 204).
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.
Warning!
G
Distronic adaptive cruise control is no sub-
stitute for active driving involvement. It does
not react to stationary objects, nor recog-
nize or predict the curvature and lane layout
or the movement of vehicles ahead. Distron-
ic can only apply a maximum of 20% of the
vehicle’s braking power.
