Vehicle Damage Warnings
Also, in this book you will find 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 specific component, control,
message, gage or indicator.
If you need help figuring out a specific 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 traction control switch is off, your vehicle will not
go into FIRST (1) gear and the vehicle will accelerate
from stop more slowly. This can help in deep snow
or mud conditions. When the traction control is turned
off, a message will light up on the Driver Information
Center (DIC).
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.This vehicle has a PUSH TO RELEASE parking brake
pedal. 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.
If you try to drive with the parking brake on, after about
20 feet (6.1 m) a chime will sound continuously until
you release the parking brake. Also, the brake light will
stay on until the parking brake is released.
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 4-37.

;(Parking Lamps):Turn the control to this position
to turn on the parking lamps together with the
following:
•Sidemarker Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
The parking brake indicator light will come on and stay
on while the parking lamps are on with the engine
off and the ignition in ACC or ON.
2(Headlamps):Turn the control to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
Your vehicle may be equipped with High Intensity
Discharge (HID) headlamps. These headlamps come on
at a lower intensity and gradually increase to full
brightness.
Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. To operate, the Twilight Sentinel
®
feature must be turned on.
When the exterior lamp control is in the off or parking
lamp position and the wiper control is on INT, LO or HI,
the HEADLAMPS SUGGESTED message will appear
on the Driver Information Center (DIC).
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the Twilight Sentinel
®
or the windshield wipers are turned off.
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.
3-17

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
“Battery Saver Active Message” underDIC Warnings
and Messages on page 3-55.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, cigarette lighters or the garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened
or the courtesy lamp switch is turned on.
Ultrasonic Rear Parking Assist
(URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at speeds
less than 3 mph (5 km/h). URPA can help you avoid
colliding with objects such as parked vehicles. The
system can detect objects 5 feet (1.5 m) behind your
vehicle and tell you how close those objects are to your
rear bumper.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate
above typical backing speeds of 3 mph
(5 km/h) while parking. And, the system does
not detect objects that are more than 5 feet
(1.5 meters) behind the vehicle.
CAUTION: (Continued)

Warning Lights, Gages and
Indicators
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 briefly 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. 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 also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-52for
more information.
