•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.
