.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
The brake system warning light
should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by
your dealer.
{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.
If the light comes on while driving, a
chime sounds. Pull off the road and
stop. The pedal might be harder to
push or go closer to the floor.
It might also take longer to stop.
If the light is still on, have the
vehicle towed for service. See

applied. If the light continues
flashing after the parking brake is
released, or while driving, there is a
problem with the electric parking
brake system. A message may also
display on the Driver Information
Center (DIC). See Brake System
Messages on page 5‑30 for more
information.
If the light does not come on,
or remains flashing, see your dealer.
The parking brake warning light
should come on briefly when the
ignition is placed in ON/RUN. If it
does not come on, have the vehicle
serviced by your dealer.

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. See Parking
Brake on page 9‑34 for more
information.

while driving, stop as soon as it is
safely possible and turn the ignition
off. A chime may also sound when
the light comes on steady. Then
start the engine again to reset the

Traction Control System
(TCS)/StabiliTrak®Light
The Traction Control System (TCS)/
StabiliTrak light comes on briefly
when the engine is started.
If the light does not come on, have
the vehicle serviced by the dealer.
If the system is working normally,
the indicator light turns off.If the light is on while certain DIC
messages display, this indicates
that the TCS and StabiliTrak
systems are not working or are
disabled.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. Check
the DIC messages 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 StabiliTrak 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
StabiliTrak system is actively
working.
