Engine Coolant Temperature Gage; Malfunction Indicator Lamp - GMC 2006 Canyon Owner's Manual

Engine Coolant Temperature Gage

If the gage pointer is near the top of the gage, the
engine is too hot. It means that your engine coolant has
overheated. If you have been operating your vehicle
under normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine as
soon as possible.
See Engine Overheating on page 5-28 for more
information.

Malfunction Indicator Lamp

Check Engine Light
This system is called OBD II (On-Board
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 is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
