Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you 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.
You'll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the following
topics:
·Seats and Restraint Systems in Section 1
·Features and Controls in Section 2
·Instrument Panel Overview in Section 3
·Climate Controls in Section 3
·Warning Lights, Gages and Indicators in Section 3
·Audio System(s) in Section 3
·Engine Compartment Overview in Section 5

If the ignition is on, the brake system warning and
parking brake indicator light on the instrument panel
cluster should come on. If it doesn't, you need to have
your vehicle serviced.
When you move out of PARK (P) or NEUTRAL (N) and
the engine is running, the parking brake should
release. If the parking brake has not been fully released
and you try to drive off with the parking brake on, the
brake system warning and parking brake indicator
light will come on and stay on and a multiple chime will
sound. See
Brake System Warning and Parking
Brake Indicator Light on page 3-47for more information.If the parking brake doesn't fully release, you can
manually release the pedal. However, be sure to read
the following paragraphs:
{CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The
pedal springs back quickly. Keep your hand
and arm away when you use the manual
release lever.

Section 3 Instrument Panel
3-1

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
¯ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ¯ash to
signal a lane change. Hold it there until the lane change is
complete. The lever returns when it's released.
If the turn signal is left on, a warning chime will sound and
the Driver Information Center (DIC) will display TURN
SIGNAL ON after driving about a mile to remind you to
turn it off.
Arrows that ¯ash rapidly when signaling for a turn or lane
change may be caused by a burned out signal bulb.
Other drivers won't see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if the
arrow fails to work when signaling a turn. See
Fuses and
Circuit Breakers on page 5-94.
Headlamp High/Low-Beam Changer
Push forward to change the headlamps from low beam
to high. Pull the lever back and then release it to
change from high beam to low.
This light on the instrument
panel cluster will be on,
indicating high-beam
usage.
Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull and hold the turn signal lever toward you
to use. When you do, the following will occur:
·If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to
turn them off.
·If the headlamps are on high beam, they will switch
to low beam. To return to high beam, push the
lever away from you.
3-9

Lamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
Daytime Running Lamps
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. Fully functional daytime running
lamps are required on all vehicles ®rst sold in Canada.
The DRL system will make the low-beam headlamps
come on at reduced intensity when the following
conditions are met:
·It is still daylight and the ignition is on,
·the exterior lamp control is in the off position and
·the transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps at
reduced brightness will be on. No other exterior lamps
such as the parking lamps, taillamps, etc. will be on when
the DRL are being used. Your instrument panel won't be
lit up either.
When the Twilight Sentinel
žlever is on and it's dark
enough outside, the high-beam headlamps at reduced
intensity will turn off and normal low-beam headlamp
operation will occur.When the Twilight Sentinel
žlever is on and it's bright
enough outside, the regular lamps will go off, and
the high-beam headlamps at reduced brightness will
take over. If you start your vehicle in a dark garage, the
automatic headlamp system will come on immediately.
Once you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
knob is in the full bright position. See ªInstrument Panel
Brightnessº under
Interior Lamps on page 3-19.
If it's dark enough outside and the Twilight
Sentinel
žlever is off, a HEADLAMPS SUGGESTED
message will display on the Driver's Information Center
(DIC). This message informs the driver that turning
on the exterior lamps is recommended even though the
DRL are still illuminated.
Turning on the Twilight Sentinel
žor the headlamps will
deactivate the DRL and remove the HEADLAMPS
SUGGESTED message. If the parking lamps or the fog
lamps were turned on instead, the DRL will still deactivate
and the HEADLAMPS SUGGESTED message will
continue to be displayed.
To idle your vehicle with the DRL off at night, turn off the
Twilight Sentinel
žand shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
3-16

Reading Lamps
The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than
normal to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the fan may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº under
DIC Warnings
and Messages on page 3-60.
3-21

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that may
be on your 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
your 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 your vehicle's functions. As you will
see in the details on the next few pages, some
warning lights come on brie¯y when you start the
engine just to let you know they're 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's 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. Follow this manual's
advice. Waiting to do repairs can be costly ± and even
dangerous. So please get to know your warning
lights and gages. They're a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
See
Driver Information Center (DIC) on page 3-57for
more information.
Instrument Panel Cluster
The instrument panel cluster is designed to let you
know at a glance how your vehicle is running. You'll
know how fast you're going, how much fuel you're using
and many of the other things you'll need to know to
drive safely and economically.
3-40

Brake System Warning and Parking
Brake Indicator Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part isn't 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, there is a brake problem.
Have your brake system inspected right away.
This light should come on
brie¯y when you turn the
ignition key to ON. If it
doesn't come on
then, have it ®xed so it will
be ready to warn you if
there's 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 doesn't fully
release. If it stays on after your parking brake is
fully released, it means you have a brake problem.
{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've pulled off the road and stopped
carefully, have the vehicle towed for service.
If the light comes on while you are driving, 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. See
Towing
Your Vehicle on page 4-31.
3-47

Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while you're driving, your vehicle
needs service. If the regular brake system warning
light isn't on, you still have brakes, but you don't have
anti-lock brakes. If the regular brake system warning
light is also on, you don't have anti-lock brakes
and there's a problem with your regular brakes. See
Brake System Warning and Parking Brake Indicator
Light on page 3-47.
The anti-lock brake system warning light should come
on brie¯y when you turn the ignition key to ON. If
the light doesn't come on then, have it ®xed so it will be
ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
This warning light should come on brie¯y when the
engine is started.
If the warning light doesn't come on then, have it ®xed
so it will be ready to warn you if there's a problem.
If it stays on, or comes on when you're driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly.
