WARNING Risk of accident due to
objects in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tra vel or block a depressed pedal.
This jeopardises the operating and road
saf ety of theve hicle. #
Stow all objects in theve hicle securely
so that they cannot getinto the driver's

DANG ER Risk of fata l injuries due to
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and can lead topoisoning. #
Never lea vethe engine running in an
enclosed space wi thout suf ficient venti‐
lation. &
WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #

DANG ER Risk of fata l injuries due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case, forex ample, if theve hi‐
cle is stuck in sn ow. #
When the engine or thest ationary
heater are running, keep theta ilpipe
and the area around theve hicle clear of

Open a window on the side of theve hi‐
cle facing the wind toensure an ade‐
qu ate supply of fresh air. &
WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
