on to show it is in use. The light
comes on when the ignition is in
ON/RUN, equipment requiring less
than 150 watts is plugged into the
outlet, and no system fault is
detected.The indicator light does not come on
when the ignition is in LOCK/OFF or
if the equipment is not fully seated
into the outlet.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the Retained
Accessory Power (RAP) off and
then back on. See
Retained
Accessory Power (RAP) on

Service Electric Parking
Brake Light
On some vehicles the service
electric parking brake light should
come on briefly when the vehicle is
in ON/RUN. If it does not come on,
have it fixed so it will be ready to
warn if there is a problem. For
vehicles with the reconfigurable
cluster, this light may not come on
when the vehicle is in ON/RUN.
If this light stays on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. SeeElectric
Parking Brake on page 9-28. If a message displays in the Driver
Information Center (DIC), see
Brake
System Messages on page 5-36.
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady. If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning.
If both the ABS and the brake
system warning light are on, the
vehicle's antilock brakes are not
functioning and there is a problem
with the regular brakes. See your
dealer for service.
