lock when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
using the control system (
page 127).

to unlock the passenger door from the in-
side or want to lock the vehicle before
starting to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking switch.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold.

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures
Remove unnecessary loads
Allow engine to warm up under low
load use
Avoid frequent acceleration and decel-
eration
Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Light Truck Center
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/or taking drugs
and driving are a very dangerous combina-
tion. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident is sharply increased when you drink
or take drugs and drive.
Don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking
drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.
