Starting the Engine To place the transmission in the proper gear: Move the shift lever to P (Park) or N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral). Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped. The keyless access transmitter must be inside the vehicle for the ignition to work. Cell phone chargers can interfere with the operation of the Keyless Access System. Battery chargers should not be plugged in when starting or turning off the engine. To start the vehicle, do the following: 2. When the engine begins cranking, let go of the button and the engine cranks automatically until it starts. If the battery in the keyless access transmitter is weak, the DIC displays KEY FOB BATTERY LOW. You can still drive the vehicle. See "Battery Replacement" under Keyless Access System Operation on page 3‑5 for more information. If the fob battery is dead, you need to insert the fob into the fob slot to enable engine starting. See "No Fobs Detected" under DIC Warnings and Messages on page 4‑76. 3. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. 4. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again to let the cranking motor cool down. 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 to the floor while cranking for up to 15 seconds maximum. Starting Procedure 1. With your foot on the brake pedal, press the START button located on the instrument panel. If there is not a keyless access transmitter in the vehicle or if there is something causing interference with it, the DIC will display NO FOBS DETECTED. See DIC Warnings and Messages on page 4‑76 for more information. 3-27
