Note: 
For safety reasons, the soft top cannot be raised while 
driving.
Warning! 
The soft top is not fully closed and locked: 
• if the indicator lamp in the soft top switch does 
not got out (electronic key in steering lock 
position 2). • if the indicator lamp blinks, and a signal 
sounds for 10 seconds when starting to drive. Stop the vehicle and before continuing to drive, 
close and lock the soft top. If the soft top is not locked, it may fold back or 
forward when driving. During soft top operation, do not place your hands 
near the roll bar, soft top frame, upper windshield 
area or soft top storage compartment. Serious 
personal injury may occur. To prevent possible accidents, drive the vehicle 
only with the soft top either completely closed and 
locked, or fully lowered into its storage 
compartment. If the indicator lamp in the soft top switch blinks slowly 
while activating the switch, 
•the battery voltage may be insufficient – start 
engine and let it run while activating switch, 
•the system may be overheated (for example after 
lowering or raising the soft top approx. 5 
consecutive times) – after approx. 10 minutes the 
soft top switch may be activated again. 
If indicator lamp in the soft top switch blinks rapidly 
while activating the switch, 
•the trunk lid and/or the luggage cover may be open, 
and need to be closed, 
•the soft top is still locked during the opening 
procedure and needs to be unlocked, 
•the opening/closing procedure is interrupted.
If the indicator lamp continues to blink, raise the soft 
top manually, see page280.
Have the system checked at your authorized 
Mercedes-Benz Center as soon as possible.

Starting and turning off the engine

Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector 
lever is in position “P” or “N”. Turn electronic key in 
steering lock to position 2.
Starting
Do not depress accelerator.
Briefly turn electronic key in steering lock clockwise to 
the stop and release. The starter will engage until the 
engine is running.
If engine will not run, and the starting procedure stops, 
turn electronic key completely to the left and repeat 
starting the engine.
After several unsuccessful attempts, have the system 
checked at the nearest authorized Mercedes-Benz 
Center.Important!
Due to the installed starter non-repeat feature, the 
electronic key must be turned completely to the left 
before attempting to start the engine again.
In areas where temperatures frequently drop below -4°F 
(-20°C) we recommend that an engine block heater be 
installed. Your authorized Mercedes-Benz Center will 
advise you on this subject.
Turning off
Turn the electronic key in the steering lock to position 0 
to stop the engine.
The electronic key can only be removed with the 
selector lever in position “P”.

Automatic transmission
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”, see page 204 for parking brake. When parked on an incline, also turn front wheel 
against curb.

and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Caution!
Never change the program mode when the selector lever 
is out of position “P”. It could result in a change of 
driving characteristics for which you may not be 
prepared.
Important!
Always be certain of the program mode selected since 
the vehicle driving characteristics change with the 
selection of the program mode.
Dependent on the program mode selector switch 
position “S” or “W” and the gear selector lever in 
position “R”, the ratio of power transmission changes.
Emergency operation (Limp home mode)
If vehicle acceleration worsens or the transmission no 
longer shifts, the transmission is most likely operating 
in Limp home mode which engages when there is a 
malfunction of the transmission. This condition may be 
accompanied by the “CHECK ENGINE” malfunction 
indicator lamp in the instrument cluster coming on.In this mode only the 2nd gear or reverse gear can be 
activated.
To engage 2nd gear or reverse:
1. Stop the vehicle.
2. Move selector lever to position “P”.
3. Turn off the engine.
4. Wait approx. 10 seconds.
5. Restart the engine.
6. Move selector lever to position “D” (for 2nd gear), or 
move selector lever to position “R” (for reverse gear).
Have the transmission checked at your authorized 
Mercedes-Benz Center as soon as possible.
