The battery could be drained if you leave the key in theACC/ACCESSORY or ON/RUN position with the engineoff. You may not be able to start the vehicle if the batteryis allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver InformationCenter (DIC) will display DRIVER DOOR OPENwhen the driver door is opened if the ignition is inLOCK/OFF, ACC/ACCESSORY and the key is in theignition. SeeDIC Warnings and Messages on page 4-67for more information.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to10 minutes after the ignition key is turned off:
•Audio System
•Audio Steering Wheel Controls
•Power Windows
•Sunroof (if equipped)
Power to these accessories will work up to 10 minutesor until the driver’s door is opened. For an additional10 minutes of power, close all the doors and turn the keyto ON/RUN and then back to LOCK/OFF.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral). Theengine will not start in any other position. To restart theengine when the vehicle is already moving, useN (Neutral) only.
Notice:Do not try to shift to P (Park) if the vehicleis moving. If you do, you could damage thetransmission. Shift to P (Park) only when the vehicleis stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn theignition to START. When the engine starts, let goof the key. The idle speed will slow down asthe engine warms. Do not race the engineimmediately after starting it. Operate the engine andtransmission gently to allow the oil to warm upand lubricate all moving parts.

The vehicle has a Computer-Controlled CrankingSystem. This feature assists in starting theengine and protects components. If the ignition keyis turned to the START position, and thenreleased when the engine begins cranking, theengine will continue cranking for a few seconds oruntil the vehicle starts. If the engine does notstart and the key is held in START, cranking will bestopped after 15 seconds to prevent crankingmotor damage. To prevent gear damage, thissystem also prevents cranking if the engineis already running. Engine cranking can be stoppedby turning the ignition switch to theACC/ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods oftime, by returning the key to the START positionimmediately after cranking has ended, can overheatand damage the cranking motor, and drain thebattery. Wait at least 15 seconds between each try,to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,especially in very cold weather (below 0°F or!18°C), it could be flooded with too much gasoline.Try pushing the accelerator pedal all the way tothe floor and holding it there as you hold the key inSTART for up to a maximum of 15 seconds.Wait at least 15 seconds between each try, to allowthe cranking motor to cool down. When theengine starts, let go of the key and accelerator. Ifthe vehicle starts briefly but then stops again, repeatthese steps. This clears the extra gasoline fromthe engine. Do not race the engine immediatelyafter starting it. Operate the engine andtransmission gently until the oil warms up andlubricates all moving parts.
Notice:The engine is designed to work with theelectronics in the vehicle. If you add electrical partsor accessories, you could change the way the engineoperates. Before adding electrical equipment, checkwith your dealer/retailer. If you do not, the enginemight not perform properly. Any resulting damagewould not be covered by the vehicle warranty.

Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake firmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,be sure your vehicle is in P (Park) and the parkingbrake is firmly set before you leave it. SeeParking Brakeon page 3-30for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts toomuch force on the parking pawl in the transmission.This happens when parking on a hill and shiftingthe transmission into P (Park) is not done properly andthen it is difficult to shift out of P (Park).
To prevent torque lock, set the parking brake and thenshift into P (Park). To find out how, see “ShiftingInto Park” in this section.
If torque lock does occur, your vehicle may need to bepushed uphill by another vehicle to relieve the parkingpawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.The shift lock release is designed to:
•Prevent ignition key removal unless the shift lever is
in P (Park)
•Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN orACC/ACCESSORY and the regular brake pedal isapplied.
The shift lock is always functional except in the case of aan uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery withlow voltage, try charging or jump starting the battery.SeeJump Starting on page 6-36.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have ormight begin programs to inspect the emission controlequipment on the vehicle. Failure to pass this inspectioncould prevent getting a vehicle registration.
Here are some things to know to help the vehicle passan inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if thekey is in ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determinesthat critical emission control systems have not beencompletely diagnosed by the system. The vehiclewould be considered not ready for inspection.This can happen if the battery has recently beenreplaced or if the battery has run down. Thediagnostic system is designed to evaluate criticalemission control systems during normal driving.This can take several days of routine driving. If thishas been done and the vehicle still does notpass the inspection for lack of OBD II systemreadiness, your dealer/retailer can preparethe vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance candamage the engine. The repairs would not becovered by the vehicle warranty. Always follow themaintenance schedule in this manual for changingengine oil.
This light comes on briefly while starting the engine.If it does not, have the vehicle serviced by yourdealer/retailer. If the system is working normally theindicator light then goes off.
