Retained Accessory Power (RAP) The following accessories can be used for up to 10 minutes after the engine is turned off... Notice: Do not try to shift to P (Park) if the vehicle is moving.

Audio System Audio Steering Wheel (if equipped) Clock Power Windows Sunroof (if equipped) Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition to START. When the engine starts, let go of the key. The idle speed will slow down as the engine warms. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in START, cranking will be stopped after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Power to these accessories works up to 10 minutes or until the driver door is opened. The instrument panel cluster lights stay on for a few seconds, then will go out. Once the driver door is opened, the power shuts off to these accessories. The vehicle has a feature designed to protect the battery against drainage. For more information see Inadvertent Power Battery Saver on page 4 ‑ 14 and Electric Power Management on page 4‑14. Starting the Engine Move the shift lever to P (Park) or N (Neutral). The engine will not start in any other position. To restart the engine when the vehicle is already moving, use N (Neutral) only. 3-21
