Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the

the following:
Taillamps
License Plate Lamps
Sidemarker Lamps
Instrument Panel Lights
2(Headlamps):Turn the control to this position

A warning chime will sound if the driver’s door is

-(Foglamps):If your vehicle has fog lamps,
press this button to turn them on and off. SeeFog
Lamps on page 160for additional information.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. DRL lamps are required to function at
all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system will make the low-beam
headlamps come on at reduced brightness when
the following conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness.
The turn signal, taillamps, sidemarker, and other
lamps will not be on. The instrument panel will not
be lit up either.

10. Install a new passenger compartment air lter.
SeeNormal Maintenance Replacement Parts
on page 471for the type of lter to use.
Make sure it slides under the compartment
retainers.
11. Reverse Steps 1 through 8.
For best climate control performance,
re-installation of a clean air lter is required.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures will
help you 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
you will see in the details on the next few pages,
some warning lights come on briey when you
start the engine just to let you know 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 your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous. So
please get to know the warning lights and gages.
They are a big help.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on and the parking
brake is not applied, there is a brake problem.
Have your brake system inspected right away.
This light should come
on briey when you turn
the ignition key 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 you set your
parking brake. The light will stay on if your parking
brake does not release fully. If it stays on after
your parking brake is fully released, it means you
have a brake problem.If the light comes on while you are driving, a
chime will sound and you should pull off the road
and stop carefully. You may notice that the
pedal is harder to push. Or, the pedal may go
closer to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 325.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
