03 07.09 IN CASE OF AN EMERGENCY IF YOUR ENGINE STALLS WHILE DRIVING If your engine stalls while driving ...1. Reduce your speed gradually, keeping a straight line. Move cautiously off the road to a safe place. 2. Turn on your emergency flashers. 3. Try starting the engine again. If the engine will not start, see "If your vehicle will not start". IF YOU CANNOT INCREASE THE ENGINE SPEED If the engine speed does not increase with the accelerator pedal depressed down to about the middle position, there may be a problem somewhere in your electronic throttle control system. At this time, if you depress the accelerator pedal more firmly and slowly, you can drive you vehicle at low speeds. Have your vehicle checked by your Lexus dealer as soon as possible. Even if the abnormality of the electronic throttle control system is corrected during low speed driving, the system may not be recovered until the engine is stopped and the ignition key is turned to "ACC" or "LOCK" position. CAUTION If the engine is not running, the power assist for the brakes and steering will not work, so steering and braking will be much harder than usual. CAUTION Be especially careful to prevent erroneous pedal operation. 280
