Warning Lights, Gauges, And Indicators - GMC 2012 Terrain Owner's Manual

Certain accessory plugs may not
be compatible with the accessory
power outlets and could overload
vehicle and adapter fuses. If a
problem is experienced, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See Add-On Electrical
Equipment on page 9 67.
Notice: Hanging heavy
equipment from the power
outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed
for accessory power plugs only,
such as cell phone charge cords.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to
the warning lights and gauges
could prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Instruments and Controls
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.
