Starting and Turning Off
Diesel Engine
Before Starting
Engage parking brake and ensure
selector lever is in position "P" or "N".
Turn key in steering lock to position 2.
Starting
Turn electronic key to steering lock
position 2. Preglow indicator lamp
should come on with cold engine. The
preglow process starts. When the
preglow indicator lamp goes out, the
engine is ready for 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 dealer.
Turning off
Turn the key in the steering lock to
position 0 only when the vehicle has
stopped moving.
The key can only be removed with the
selector lever in position "P".
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.
If the preglow indicator lamp fails to
light up, or lights up while driving, the
preglow system is defective and should
be repaired at your authorized
Mercedes-Benz dealer at the earliest
possible date.
The engine is equipped with a block
heater to provide reliable starting at
temperatures below 0°F(-18°C). Refer
to Winter Driving in Index.
