FORD 1998 F-150 - Manual (Page 77)

Do not start your vehicle
in a closed garage or in
other enclosed areas. Exhaust
fumes can be toxic. Always open
the garage door before you start
the engine. See Guarding
against exhaust fumes in this
chapter for more instructions.
If you smell exhaust fumes
inside your vehicle, have
your dealer inspect your vehicle
immediately. Do not drive if you
smell exhaust fumes.
Important safety precautions
A computer system controls the
engine’s idle revolutions per
minute (RPM). When the engine
starts, the idle RPM runs faster to
warm the engine. If the engine idle
speed does not slow down
automatically, have the vehicle
checked. Do not allow the vehicle
to idle for more than ten minutes.
Before starting the vehicle:
1. Make sure all vehicle occupants
have buckled their safety belts. For
more information on safety belts
and their proper usage, refer to
the Seating and safety restraints
chapter.
2. Make sure the headlamps and
vehicle accessories are off.
