'06 Solara_U (L/O 0502) 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 the ignition key is turned to "ACC" or "LOCK" position. 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" (automatic) or neutral (manual) 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 and make sure the electric cooling fan is operating. If it is not, turn the ignition off. 3. 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 coolant is leaking, stop the engine immediately. Call a Toyota dealer for assistance. 5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. For the coolant type, see "Coolant type selection" on page 303 in Section 7 −2. CAUTION Be especially careful to prevent erroneous pedal operation. CAUTION 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. Do not attempt to remove the radiator cap when the engine and radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure. 260 2006 SOLARA from Feb.
