Engine Exhaust
Danger!
Engine exhaust is dangerous if inhaled.
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas. Carbon monoxide can
cause unconsciousness and even death if
inhaled.
Never start or let the engine run in an
enclosed, unventilated area. It is not rec-
ommended to sit in your car for prolonged
periods with the engine on and the car not
moving.
Ground Clearance
Caution!
Risk of damage. The vehicle may touch
the ground as a result of reduced ground
clearance.
Drive carefully and slowly on steep slopes
(e.g. parking lots, curbs, uneven roads, lifting
platforms, etc.).
Avoid steep ramps.
