(d) Starting the engine after a battery discharge With smart key system only- In the event that the battery is discharged, the engine may not restart even after the battery is recharged or replaced. For safety reasons, the engine may be disabled when battery voltage is extremely low. If the engine is disabled, the start system must be normalized. To normalize the start system: 1. Shift the transmission to the "P" position and set the ignition switch off. 2. Open and close any of the doors. 3. Start the engine. 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. Set the ignition switch to ACC or off, and try starting the engine again. If the engine will not start, see "If your vehicle will not start" on page 314 in this Section. If you cannot increase engine speed If engine speed does not increase when the accelerator pedal is depressed, there may be a problem somewhere in the electronic throttle control system. At this time, vibration may occur. However, if you depress the accelerator pedal more firmly and slowly, you can drive your vehicle at low speeds. Have your vehicle checked by your Toyota 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 set the ignition switch to ACC or off. CAUTION D 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. D Vehicles with smart key system- If the engine stalls while driving, do not open the driver's door until the vehicle comes to a complete stop. Opening the driver's door locks the steering wheel, resulting in loss of steering control. 318
