Starting
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.
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the risk of
fire or other damage.
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine compartment
and exhaust system, which can start a fire.
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.
