B (ACCESSORY): This position lets you use things like the radio and the windshield wipers when the engine is off. Notice: Lengthy operation of features such as the radio in the accessory ignition position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the accessory ignition position for a long period of time. C (RUN): This is the position for driving. D (START): This position starts the engine. Starting the Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position - that is a safety feature. To restart when you are already moving, use NEUTRAL (N) only. Notice: Do not try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped. 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. Your vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects the electrical system. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking until the vehicle starts or until it exceeds the maximum cranking time allowed, approximately 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. The engine cranking can be stopped by turning the ignition switch to the ACCESSORY or LOCK position. Retained Accessory Power (RAP) Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow certain features of your vehicle to continue to work up to 20 minutes after the ignition key is turned to LOCK. Your radio, power windows, sunroof (option) and overhead console will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to LOCK, these features will continue to work for up to 20 minutes or until a door is opened. 2-20
