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
following topics:

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
A (OFF):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off. To use
ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR OPEN when
the driver’s door is opened if the ignition is in OFF,
ACCESSORY and the key is in the ignition. SeeDIC
Warnings and Messages on page 3-56for more
information.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
power windows, clock, radio, and if the vehicle has
them, audio steering wheel controls and sunroof. The
power to the accessories can last up to 10 minutes. The
instrument panel cluster lights will stay on for a few
seconds, then will go out. Once you open a door, the
power will shut off. Your vehicle has a feature designed
to protect the battery against drainage. For more
information seeInadvertent Power Battery Saver on
page 3-18.
2-22

Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle speed is greater
than 5 mph (8 km/h). The brake light will come on and
stay on until the parking brake is released. See
Brake System Warning Light on page 3-40for more
information.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-36.

Wiper Activated Headlamps
This feature turns on the low-beam headlamps,
instrument panel cluster backlighting and taillamps
when the windshield wipers have been in use for about
six seconds.
If the wiper activated headlamps are on and the ignition
switch is turned to C (RUN), the wiper activated
headlamps will continue. When you turn the key to
A (OFF), the wiper activated headlamps will immediately
turn off. The wiper activated headlamps will also turn
off if you turn off the windshield wipers.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
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.A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.
The DRL system will make your low-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transaxle is not in PARK (P).
When the DRL are on, only your low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn the exterior lamp control to the off position.
The exterior lamps will turn back on automatically
when you move the transaxle out of PARK (P).
SeeExterior Lamps on page 3-14for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

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 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 your warning
lights and gages. They are a big help.
Your vehicle may also have a DIC that works along with
the warning lights and gages. SeeDriver Information
Center (DIC) on page 3-50.
