7-8 Starting and operating started. The fuel injection system automatically lowers the idle speed as the engine warms up. While the engine is warming up, make sure that the select lever is at the "P" or "N" position and that the parking brake is applied. Stopping the engine WARNING Do not stop the engine when the vehicle is moving. This will cause loss of power to the power steering and the brake booster, making steering and braking more difficult. It could also result in accidental activation of the "LOCK" position on the ignition switch, causing the steering wheel to lock. The ignition switch should be turned off only when the vehicle is stopped and the engine is idling. Remote engine start system (dealer option) WARNING . Do not start the engine using the remote start system in an enclosed environment (e.g. closed garage). Prolonged operation of a motor vehicle in an enclosed environment can cause a harmful build-up of Carbon Monoxide. Carbon Monoxide is harmful to your health. Exposure to high levels of Carbon Monoxide can cause headaches, dizziness or in extreme cases unconsciousness and/or death. . Before performing any servicing of the vehicle, temporarily place the remote engine start system in service mode to prevent the system from unexpectedly starting the engine. NOTE . The engine may be difficult to start when the battery has been disconnected and reconnected (for maintenance or other purposes). This difficulty is caused by the electronically controlled throttle's self-diagnosis function. To overcome it, keep the ignition switch in the "ON" position for approximately 10 seconds before starting the engine. . To protect the engine while the select lever is in the "P" or "N" position, the engine is controlled so that the engine speed may not become too high even if the accelerator pedal is depressed hard.
