5-24 Instruments and Controls
.The vehicle will not pass
this inspection if the OBD II
(On-Board Diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would
be considered not ready for
inspection. This can happen
if the 12‐volt battery has
recently been replaced or
if the 12‐volt battery has 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.
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.

Electric Parking Brake
Light
This status light comes on when
the parking brake is applied. If the
light flashes and stays on after the
parking brake is released, or while
driving, there is a problem with the

or remains flashing, see your dealer.
SeeElectric Parking Brake on
page 9‑35 for more information.
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 it fixed so it
will be ready to warn if there is a
problem. 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 9‑35 for

This 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 the ABS warning light stays on
longer than a few seconds after the
vehicle is in ON/RUN, or comes
on and stays on while driving, try
resetting the system. To reset the

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 well. Have the vehicle towed for
service. See
