Perimeter lighting feature
The perimeter lighting feature illuminates the exterior of the vehicle in
order to provide better visibility to the user while he or she approaches
and enters the vehicle.
The perimeter lighting feature activates when:
•the ignition is in the 1 (OFF/LOCK) position,
•the autolamp sensor determines that it is dark, and
•the user activates an unlock feature, using either the remote keyless
transmitter or the keypad.
The perimeter lighting feature will illuminate the headlamps and parking
lamps for 25 seconds, or until:
•the ignition is turned to any position other than the 1 (OFF/LOCK)
position, or
•the user activates a lock feature, using either the remote keyless
transmitter or the keypad.

vehicle doors must be closed before beginning the procedure. You must
complete Steps 1–5 within 30 seconds, or the procedure will have to be
repeated. If the procedure needs to be repeated, you must wait a

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. If the vehicle is operated in a
heavy snow storm or blowing snow conditions, the engine air induction
may become partially clogged with snow and/or ice. If this occurs the
engine may experience a significant reduction in power output. At the
earliest opportunity, clear all snow and/or ice away from the air induction
inlet. 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.
3. Make sure the gearshift is in P
(Park).
