IN CASE OF AN EMERGENCY NOTICE Do not pull- or push-start the vehicle. It may damage the vehicle or cause a collision when the engine starts. Also the three-way catalytic converter may overheat and become a fire hazard. If the engine turns over at its normal speed but will not start - 1. Turn the ignition key to "ACC" or "LOCK" and try starting the engine again. 2. The engine may be flooded because of repeated cranking. See "(b) Starting a flooded engine" for further instructions. 3. If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See "Foreword".) (b) Starting a flooded engine If the engine will not start, your engine may be flooded because of repeated cranking. If this happens, turn the ignition key to "START" with the accelerator pedal fully depressed, and hold the key at this position for about 30 seconds. Then the cranking hold function stops cranking automatically, and you can try starting the engine with your foot off the accelerator pedal. If the engine does not start, wait a few minutes and try again. If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See "Foreword".) (c) Jump starting To avoid serious personal injury and damage to your vehicle which might result from battery explosion, acid burns, electrical burns, or damaged electronic components, these instructions must be followed precisely. 492
