03 07.09 IN CASE OF AN EMERGENCY IF YOUR VEHICLE WILL NOT START (a) Simple checks Before making these checks, make sure you have followed the correct starting procedure instructions in "How to start the engine" on page 237 and that you have sufficient fuel. Since your vehicle is equipped with the engine immobilizer system, also check whether the other keys will start the engine. If they work, your key may be broken. Have the key checked at your Lexus dealer. If none of your keys work, there may be a malfunction in the immobilizer system. Call your Lexus dealer. See "Keys" on page 8. If the engine is not turning over or is turning over too slowly 1. Check that the battery terminals are tight and clean. 2. If the battery terminals are O.K., switch on the interior light. 3. If the light is out, dim or goes out when the starter is cranked, the battery is discharged. You may try jump starting. See "(c) Jump starting" for further instruction. If the light is O.K., but the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See "Foreword".) 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. The engine may be flooded because of repeated cranking. See "(b) Starting a flooded engine" for further instructions. 2. If the engine still will not start, it needs adjustment or repair. Call a Lexus dealer, Roadside Assistance or Customer Service Assistance. (See "Foreword".) 281
