Information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, e.g. with a wheel chock. ◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession. ◀
