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. SeeGuarding against exhaust fumesin
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 higher than normal in
order 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 10 minutes at the higher engine RPM.
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 Restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.
