GMC 2007 Automobile User Manual


 
The ABS warning light will come on briefly when
you turn the ignition to ON. This is normal. If the
light does not come on then, have it fixed so it will
be ready to warn you if there is a problem.
Hold Mode Light
If your vehicle has this
feature, this light will
come on when the hold
mode is active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” under Automatic
Transaxle Operation on page 111 for additional
information on this feature.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of the
fuel, ignition, and
emission control
systems.
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.
