be displayed.The HUD image displayed on the windshield will
automatically dim and brighten to compensate for
outside lighting.
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

Care of the HUD
Clean the inside of the windshield as needed to remove
any dirt or lm 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.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on the vehicle. The pictures help to locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As
the details show on the next few pages, some warning
lights come on briey when the engine is started
just to indicate they are working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate when there is a
problem with the vehicle.
When one of the warning lights comes on and stays on
while the vehicle is being driven, or when one of the
gages shows there may be a problem, check the section
that tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and
even dangerous. So please get to know the vehicle’s
warning lights and gages. They can be a big help.
The vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-49for
more information.

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,
though, both parts should be working well.
This light should come on briey when the ignition
key is turned to RUN. If it does not come on then,
have it xed so it will be ready to warn you if there
is a problem.When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means the vehicle has a brake problem.
The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set and the vehicle is going faster than 5 mph.
SeeDIC Warnings and Messages on page 3-69for
more information.
The brake warning light may also come on when the
brake uid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-69for more information.
If the brake warning light comes on while the vehicle
is being driven, pull off the road and stop carefully.
The brake pedal may be harder to push, or it may go
closer to the oor. It may also take the vehicle longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-38. United States

have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
If the vehicle has the
Anti-lock Brake System
(ABS), this light will come

may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
the vehicle still has brakes, but it does not have anti-lock
brakes. SeeBrake System Warning Light on page 3-40.
If the light stays on, the vehicle needs service. If the
light comes on while the vehicle is being driven, stop as
soon as possible and turn the ignition off. Then start
the vehicle again to reset the system. If the light
still 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 it
does not have anti-lock brakes. If the brake system
warning light is also on, the vehicle does not have
anti-lock brakes and there is a problem with the regular
brakes. SeeBrake System Warning Light on page 3-40.
If both the brake system warning light and the anti-lock
brake system light is on, pull off the road and have
the vehicle towed for service.
The anti-lock brake system warning light will come on
briey when the ignition key is turned to RUN. This
is normal. If the light does not come on then, have it
