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

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers ®nd this to be too much trouble and don't use
cruise control on steep hills.
Ending Cruise Control
There are three ways to cancel the cruise control:
·Step lightly on the brake pedal.
·Slide the lever on the multifunction lever to the left
to the OFF position.
·Press the COAST and ACCEL buttons at the
same time.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the left
of the steering wheel.
It controls the following systems:
·Headlamps
·Taillamps
·Parking Lamps
·License Plate Lamps
·Instrument Panel Lights
3-14

The exterior lamps control has three positions:
Off:Push the control all the way in to turn off the
exterior lamps.
Parking Lamps:Pull the control out halfway to turn on
the parking lamps together with the following:
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
Headlamps:Pull the control all the way out to turn on
the headlamps together with the previously listed
lamps and lights. See
Interior Lamps on page 3-17for
information on the instrument panel brightness
control and on the dome lamps. A warning chime will
sound if you open the driver's door when the ignition
switch is off and the headlamps are on.
Daytime Running Lamps/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. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system's automatic headlamp control will
make your high-beam headlamps come on at a reduced
brightness when the following conditions are met:
·The ignition is on,
·the exterior lamps control is off and
·the gearshift is not in PARK (P).
When the DRL are on, only your high-beam headlamps,
at a reduced level of brightness, will be on. The
headlamps, taillamps, sidemarker and other lamps won't
be on. Your instrument panel and cluster won't be lit
up either.
When it's dark enough outside, your high-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it's bright enough outside, your headlamps will go
off and your DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Interior Lamps
Instrument Panel Brightness
This feature controls the instrument panel lights.
The control for this feature is located on the exterior
lamps control. Your parking lamps must be on for this
feature to work. Turn the control clockwise to brighten
the lights or counterclockwise to dim them.
Courtesy Lamps
When any door is opened, several lamps come on.
These lamps are courtesy lamps. They make it easy for
you to enter and leave your vehicle. You can also
turn these lamps on by turning the exterior lamps control
all the way clockwise.
Some of the lamps have switches so you can turn them
on, even when the doors are closed. These lamps
are reading lamps.
Entry Lighting
Your vehicle may be equipped with courtesy lamps that
will come on and stay on for a set time whenever
you press UNLOCK on the remote keyless entry
transmitter (if equipped).
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don't open
a door, the lamps will turn off after about 40 seconds.Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps don't just turn off at
the end of the delay time. Instead, they slowly dim after
the delay time until they go out. The delay time is
canceled if you turn the ignition key to ON or press
the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps won't come on unless
a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will continue to
work until one of the following occurs:
·The ignition is moved to ON,
·the doors are locked, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
