'04 Tacoma U (L/O 0309) If your engine stalls while driving Do not connect the cable to or near any part that moves when the engine is cranked. 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 (four- wheel drive models and Pre Runner with 5VZ- FE engine) 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 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 the ignition key is turned to "ACC" or "LOCK" position. 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-they 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 Toyota dealer. 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. 249 2004 TACOMA from Sep. '03 Prod. (OM35814U)
