Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates 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, 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 your brake
system inspected right away.
EnglishMetric
If the vehicle has antilock brakes,
this light should come on when the
vehicle is placed in START. If it does
not, have the vehicle serviced by
your dealer.

If the light comes on while driving,
pull off the road and stop carefully.
The pedal may be harder to push or
it can go closer to the floor. It may
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.
SeeAntilock Brake System (ABS)
Warning Light on page 5‑21 and
Towing the Vehicle on page 10‑89.
{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
EnglishMetric
For vehicles with the Electric
Parking Brake (EPB), the parking
brake status light comes on
when the brake is 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 SERVICE PARKING BRAKE
message may also display in the
Driver Information Center (DIC).
See Brake System Messages on
page 5‑33 for more information.
If the light does not come on,
or remains flashing, see your dealer.
For vehicles with the Electric
Parking Brake (EPB), the parking
brake warning light should come
on briefly when ignition is placed
in ON/RUN. If it does not come on,
then have it fixed so it will be ready
to warn if there is a problem.
If this light comes 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 Parking
Brake on page 9‑33 for more
information.
For vehicles with the uplevel cluster,
this telltale displays in the Driver
Information Center (DIC) screen.

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 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 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.
See
Brake System Warning Light on
page 5‑19.
See Brake System Messages on
page 5‑33 for all brake related DIC

for an extended period of time while
the system is turned on, the vehicle
needs service.

The HUD image displayed on
the windshield will automatically
dim and brighten to compensate
for outside lighting. However, the
HUD brightness control can still
be adjusted as needed. The HUD image can temporarily
light up depending on the angle
and position of the sunlight on the
HUD display. This is normal and
will change when the angle of
the sunlight on the HUD display
changes.
Polarized sunglasses could make
the HUD image harder to see.
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
If You Cannot See the HUD
Image When the Ignition Is On
.Is anything covering the
HUD lens?
.Is the HUD dimmer setting bright
enough?
.Is the HUD image adjusted to
the proper height?
.Are you wearing polarized
sunglasses?
.Still no HUD image? Check the
fuse in the instrument panel fuse
block. See
Instrument Panel
Fuse Block on page 10‑42.
If the HUD Image Is Not Clear
.Is the HUD image too bright?
.Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer.
Keep in mind that the windshield is
part of the HUD system.
