.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. If this were to occur, 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 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
This light comes on briefly when the
vehicle is turned on. If it does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the light comes on and stays on,
there is a base brake problem.
{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.

Service Electric Parking
Brake Light
The service electric parking brake
light should come on briefly when
the vehicle is in ON/RUN. If it does
not come on, have the vehicle
serviced by your dealer.
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. See
Electric
Parking Brake on page 9-31. If a
message displays in the Driver
Information Center (DIC), see Brake

(ABS) Warning Light
This light should come on briefly
when the vehicle is in ON/RUN. If it

serviced by your dealer. If the ABS warning light stays on
longer than a few seconds after the

and stays on while driving, try
resetting the system. To reset the
system:
1. While driving, pull over when it is
safe to do so.
2. Place the vehicle in P (Park).
3. Turn the vehicle off.
4. Restart the vehicle.
If the ABS warning light remains on
after resetting the system or comes
on again while driving, the vehicle
needs service. If the ABS warning
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 the vehicle
serviced right away. If both brake
lights are on, the vehicle does not
have antilock brakes, and there is a
problem with the regular brakes as
