The light operates to warn that the engine is almost overheating.
The high engine coolant temperature warning light will come on when the ignition key is turned to the "ON" position. After a few seconds, the light will go off.
If your engine coolant temperature is cool with the ignition switch on, the low engine coolant temperature indicator light comes on. If it keeps lighting on with the engine fully warmed, contact your Toyota dealer as soon as possible to service the vehicle.
If the high engine coolant temperature warning light flashes, your engine is too hot. If your vehicle overheats, stop your vehicle and allow the engine to cool.
Your vehicle may overheat during severe operating conditions, such as:
• Reducing speed or stopping after high speed driving.
• Idling for a long period with the air conditioning on in stop-and-go traffic.
♦ Do not remove the thermostat in the engine cooling system as this may cause the engine to overheat. The thermostat is designed to control the flow of coolant to keep the temperature of the engine within the specified operating range.
♦ Do not continue driving with an overheated engine. See "If your vehicle overheats" on page 218 in Section 4.
(p) Key Reminder Buzzer
This buzzer acts as a reminder to remove the key when you open the driver's door with the ignition key in the "ACC" or "LOCK" position.
(q) Light Reminder Buzzer
This buzzer will sound if the headlight switch is left on and the driver's door is opened with the key removed from the ignition switch.
CHECKING SERVICE REMINDER INDICATORS (except the low fuel level warning light and low windshield washer fluid level warning light)
1. Apply the parking brake.
2. Open one of the doors.
The open door warning light should come on.
3. Close all the doors.
The open door warning light should go off.
4. Turn the ignition key to "ON", but do not start the engine.
All the service reminder indicators except the open door warning light should come on. The "ABS" warning light, engine oil replacement reminder light, high engine coolant temperature warning light and electric power steering system warning light goes off after a few seconds. The SRS warning light goes off after about 6 seconds.
If any service reminder indicator or warning buzzer does not function as described above, have it checked by your Toyota dealer as soon as possible.
