If you cannot increase the engine speed If the engine speed does not increase when the accelerator pedal is depressed, the electronic throttle control system may be faulty. Move the vehicle to a safe place by means of creeping and call a Toyota dealer for assistance: 1. Depress the brake pedal and shift to the "D" position. 2. Gradually release the brake pedal, and the vehicle starts to move by creeping. After arriving at a safe place, stop the vehicle and call a Toyota dealer for assistance. If your vehicle overheats If your engine coolant temperature gauge indicates overheating, if you experience a loss of power, or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure...1. Pull safely off the road, stop the vehicle and turn on your emergency flashers. Put the transmission in "P" and apply the parking brake. Turn off the air conditioning if it is being used. 2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over or steam, leave the engine running. 3. Visually check to see if the engine drive belt (fan belt) is broken or loose. Look for obvious coolant leaks from the radiator, hoses, and under the vehicle. However, note that water draining from the air conditioning is normal if it has been used. CAUTION When the engine is running, keep hands and clothing away from the moving fan and engine drive belts. 4. If the engine drive belt is broken or the coolant is leaking, stop the engine immediately. Call a Toyota dealer for assistance. 5. If the engine drive belt is O.K. and there are no obvious leaks, you may help the engine cool down more quickly by running it at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed. 6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. CAUTION D The above method of moving the vehicle is for emergency. Use it only for moving minimum distances to a safe place. CAUTION To help avoid personal injury, keep the hood closed until there is no steam. Escaping steam or coolant is a sign of very high pressure. D Be especially careful to prevent erroneous pedal operation. 250 2004 L/C100 from Aug '03 Prod. (OM60A04U)
