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.

Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged. Note:
After reconnecting the battery also set the clock in
instrument cluster (see page 80), set date in trip
computer (see page 83), resynchronize the sliding / pop-
up roof (see page 272), the Skyview Top (see page 273)
and the electronic stability program (ESP) (see
page 206).
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.
