2010 Acura RDX Owner's Manual - Page 378

Starting the Engine Your vehicle's starting system has an auto control mode. When you turn the ignition switch to the START (III) position, this feature keeps the engine's starter motor running until the engine starts. Follow these instructions to start the engine: 1. Apply the parking brake. 2. In cold weather, turn off all electrical accessories to reduce the drain on the battery. 3. Make sure the shift lever is in Park. Press on the brake pedal. 4. Without touching the accelerator pedal, turn the ignition key to the START (III) position. Do not hold the key in the START (III) position for more than 15 seconds at a time. If the engine does not start right away, pause for at least 10 seconds before trying again. The immobilizer system protects your vehicle from theft. If an improperly coded key (or other device) is used, the engine's fuel system is disabled. For more information, see page 124. The engine is harder to start in cold weather. Also, the thinner air found at altitudes above 8,000 feet (2,400 meters) adds to this problem. 374 2010 RDX
