NOTICE
■ To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 585)
■ While driving
●When the voltmeter indicates more than 19 V or less than 9 V, the battery
may be malfunctioning. Have your vehicle checked at your Toyota dealer.
● When the engine oil pressure gauge does not work properly, immediately
stop the engine and contact your Toyota dealer.
● When the automatic transmission fluid temperature gauge needle continu-
ally points higher than normal, immediately contact your Toyota dealer. (if
equipped)

484 4-3. Do-it-yourself maintenance
Engine coolantThe coolant level is satisfactory if it is between the FULL and LOW
lines on the reservoir when the engine is cold. Reservoir cap
FULL
LOW
If the level is on or below the
LOW line, add coolant up to the
FULL line.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, as the engine could be damaged.
● Check the oil level on the dipstick every time you refill the vehicle.
● Be sure the engine oil filler cap is properly tightened.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
