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 
messagesÁ 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).

252 Battery
Te ch n ica l

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.
