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 key in steering lock
to position 2. The charge indicator lamp should come on.
Starting
Do not depress accelerator.
Briefly turn 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 key completely to the left and repeat starting the
engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz Light
Truck Center.
A starting procedure can be interrupted by turning the
key to steering lock position 0. Important!
Due to the installed starter non-repeat feature, the 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 Light Truck
Center will advise you on this subject.
Note:
In case the engine cannot be started and the
messages Á and î are shown in the odometer
display field, the system is not operational. Contact an
authorized Mercedes-Benz Light Truck Center or call
1-800-FOR-MERCedes (in the USA), or 1-800-387-0100
(in Canada).
Turning off
Turn the key in the steering lock to position 0 to stop the
engine.
The key can only be removed with the selector lever in
position “P”.

Automatic transmission
The automatic transmission selects individual gears
automatically, dependent upon
• Selector lever position
• Accelerator position
• Vehicle speed
The gear shifting process is continuously adapted,
dependent on the driving style, the driving situation
and the road characteristics.
Important!
When parking the vehicle or before working on the
vehicle with the engine running, firmly depress the
parking brake pedal and shift the selector lever into “P”.
