IN CASE OF AN EMERGENCY CAUTION When making the connections, to avoid serious injury, do not lean over the battery or accidentally let the jumper cables or clamps touch anything except the correct battery terminals or the ground. 5. Start your engine in the normal way. After starting, run it at about 2000 rpm for several minutes with the accelerator pedal lightly depressed. 6. Carefully disconnect the cables in the exact reverse order: the negative cable and then the positive cable. 7. Carefully dispose of the battery cover cloths which may now contain sulfuric acid. 8. If removed, replace all the battery vent plugs. If the cause of your battery discharging is not apparent (for example, lights left on), you should have it checked at your Lexus dealer. IF YOU CANNOT INCREASE THE ENGINE SPEED If the engine speed does not increase with the accelerator pedal depressed down, there may be a problem somewhere in your 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 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 Be especially careful to prevent erroneous pedal operation. 554
