Engine Coolant Temperature Gage; Malfunction Indicator Lamp - Chevrolet Malibu 2007 Malibu Owner's Manual

Engine Coolant Temperature Gage

United States
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area,
the light comes on and you hear a chime, your
engine is too hot! It means that your engine
coolant has overheated.
If you have been operating your vehicle under
normal driving conditions and the gage reads hot,
you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.

Malfunction Indicator Lamp

Check Engine Light
This system is called OBD II (On-Board
Canada
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
