Engine Coolant Temperature Gage; Tire Pressure Light - Pontiac 2009 G8 Owner's Manual

If the light remains on after resetting
the system or comes on again
while driving, your vehicle needs
service. If the ABS light is on,
but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there's a
problem with your regular brakes as
well. Have your vehicle towed for
service. See Towing Your Vehicle
on page 9-88.
The ABS Fault message will remain
3
until (Trip/Fuel) or
are pressed, but the warning
light will remain until the problem is
fixed. See DIC Warnings and
Messages on page 4-26 for more
information.

is too hot. It means that the engine
has overheated. Pull off the road,
stop the vehicle, and turn off the
engine as soon as possible. See
Engine Overheating on page 9-20.
