Starting the Engine Starting in Cold Weather at High Altitude (Above 8,000 feet/ 2,400 meters) An engine is harder to start in cold weather. The thinner air found at high altitude above 8,000 feet (2,400 meters) adds to the problem. Use the following procedure: 1. Turn off all electrical accessories to reduce the drain on the battery. 2. Push the accelerator pedal halfway to the floor and hold it there while starting the engine. Do not hold the ENGINE START button for more than 15 seconds. When the engine starts, release the accelerator pedal gradually as the engine speeds up and smooths out. 3. If the engine fails to start in step 2, push the accelerator pedal to the floor and hold it there while you try to start the engine for no more than 15 seconds. If the engine does not start, return to step 2. 136 Driving
