FORD 2001 Focus - Manual (Page 127)

Starting
127
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.
