Safety information
DANGER
If the exhaust pipe is blocked or ventila-
tion is insufficient, harmful exhaust gases
can penetrate the vehicle. The exhaust
gases contain pollutants which are color-
less and odorless. In enclosed areas, ex-
haust gases can also accumulate outside of
the vehicle. There is a danger to life. Keep
the exhaust pipe free and ensure sufficient
ventilation.
Warning
An unsecured vehicle can begin to move
and possibly roll away. There is a risk
of accident. Before leaving the vehicle, se-
cure the vehicle against rolling away.
In order to ensure that the vehicle is se-
cured against rolling away, follow the fol-
lowing:
– Set the parking brake.
– On uphill grades or on downhill
slopes, turn the front wheels in the
direction of the curb.
– On uphill grades or on downhill
slopes, also secure the vehicle, for in-
stance with a wheel chock.
