2. If it does not start within 10 seconds, push the accelerator pedal all the way to the floor, while you hold the ignition key in START. When the engine starts, let go of the key and let up on the accelerator pedal. Wait about 15 seconds between each try. When starting your engine in very cold weather (below 0°F or −18°C), do this: 1. With your foot off the accelerator pedal, turn the ignition key to START and hold it there up to 15 seconds. When the engine starts, let go of the key. 2. If your engine still will not start, or starts but then stops, it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing, but this time keep the pedal down for five or six seconds. This clears the extra gasoline from the engine. Notice: Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you do not, your engine might not perform properly. Any resulting damage would not be covered by your vehicle's warranty. Adjustable Throttle and Brake Pedal If your vehicle is equipped with this feature, you can change the position of the throttle and brake pedals. This feature is designed for shorter drivers, since the pedals can not move farther away from the standard position, but can move toward the driver for better pedal reach. The vehicle must be in PARK (P) for this feature to operate. The switch used to adjust the pedals is located on the driver's side door panel. Press the arrow at the end of the switch closest to you to move the pedals closer to your body. Press the arrow at the far end of the switch to move the pedals away from your body. 2-21
