the engine is not running,
as a check to show it
is working.

on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
See DIC Warnings and Messages on page 4-38 for more
information. This light could indicate that there are

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part
can still work and stop the vehicle. For good braking
both parts need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briefly when the engine is
started. If it does not come on then, have it fixed so it
will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it means
the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. Make sure the parking brake is fully
released. The pedal might be harder to push or, the pedal
could go closer to the floor. It can take longer to stop.
Try turning off and restarting the vehicle one or two times,
if the light is still on, have the vehicle towed for service.
See
Towing Your Vehicle on page 5-30 .
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. 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.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. See Brake System Warning Light on

serves as an indicator
and warning light.
This light comes on briefly while the engine is started.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the indicator/warning light is on and not flashing, the
ETS system could have been disabled. Check all related
Driver Information Center (DIC) messages to determine
whether the system has been turned off or if the system
is not working properly and the vehicle requires service.
If the ETS has been disabled, wheel spin is not limited.
If the indicator/warning light is on and flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting

Traction Control System (TCS)
Indicator/Warning Light
For vehicles with the
Electronic Stability Control
(ESC) system or the
Traction Control System
(TCS), the indicator/
warning light comes on
briefly when the engine
is started.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally
the indicator light goes off.
If this light is on while certain DIC messages display,
this indicates that the ESC and TCS are not working or
are disabled. If this light is on and not flashing, the TCS and potentially
the ESC system have been disabled. Check the DIC
messaging to determine which feature(s) is no longer
functioning and whether it is because of the driver turning
off the feature(s), or because the system is not working
properly and the vehicle requires service.
If the TCS is disabled, wheel spin is not limited. If the
ESC system is disabled, the system does not aid
in maintaining directional control of the vehicle.
If the indicator/warning light is on and flashing, the TCS
or the ESC system is actively working. Check the DIC
messaging for details to determine which system is
working. If the LOW TRACTION message appears,
the system is limiting wheel spin. If the ESC ACTIVE
message appears, the system is aiding in maintaining
directional control of the vehicle.
