prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.
