This light indicates engine coolant temperature is

speed for two to three minutes. If the light does not turn
off, shut your engine OFF and allow it to cool. See an
authorized dealer for service immediately. Refer to
“Cooling System” under “Maintaining Your Vehicle” in

Do not leave your vehicle unattended with the en-

temperature indicator if the engine overheats.
NOTE: Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.

see you local authorized dealer for system service.
34. Oil Pressure Indicator light – Base Cluster Only
This light indicates continuous high or low oil
pressure, and under normal driving conditions,

ate service should be obtained.
