168 UNDERSTANDING YOUR INSTRUMENT PANEL The light also will turn on when the parking brake is applied with the ignition switch in the ON position. NOTE: This light shows only that the parking brake is applied. It does not show the degree of brake application. 15. Transmission Temperature Indicator During sustained high speed driving on hot days, the automatic transmission oil may become too hot. If this happens, the transmission overheat indicator light will come on and the vehicle will slow slightly until the automatic transmission cools down enough to allow a return to the requested speed. If the high speed is maintained, the overheating will reoccur as before in a cyclic fashion. 16. Vehicle Security Light - If Equipped This light will flash at a fast rate for approximately 16 seconds, when the vehicle security alarm is arming, and then will flash slowly until the vehicle is disarmed. 17. Temperature Gauge The temperature gauge shows engine coolant temperature. Any reading within the normal range indicates that the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher temperature when driving in hot weather, up mountain grades, or when towing a trailer. It should not be allowed to exceed the upper limits of the normal operating range. CAUTION! Driving with a hot engine cooling system could damage your vehicle. If temperature gauge reads "H" pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the "H" and you hear continuous chimes, turn the engine off immediately, and call an authorized dealership for service.
