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:

To open a rear door when the security lock is on, do
the following:
1. Unlock the door.
2. Open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear seat will not be
able to open the rear door from the inside. You should
let adults and older children know how these security
locks work, and how to cancel the locks.
To cancel the rear door lock, do the following:
1. Unlock and open the door from the outside.
2. Move the lever all the way to the unlock symbol.
3. Do the same for the other rear door.
The rear door locks will now work normally.
Lockout Protection
The power door locks will not work if the key is in the
ignition and a door is open. You can override this feature
by holding the driver’s side power door lock switch for
more than three seconds.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-31.
2-14

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:
Your exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over
road debris.
Repairs were not done correctly.
Your vehicle or exhaust system had been
modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.
Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-31.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-25.

Outside Curb View Assist Mirror
If you have the Memory Seat and Mirrors feature, the
passenger’s outside rearview mirror includes a tilt-down
feature that operates when the shift lever is in
REVERSE (R). This feature assists the driver, improving
rear obstacle detection. When the vehicle is shifted
out of REVERSE (R), the passenger mirror will return to
its original position after a ve-second delay. This
delay prevents movement of the mirror if multiple gear
transitions (REVERSE (R) to AUTOMATIC
OVERDRIVE (
X) to REVERSE (R)) occur during a
parallel parking maneuver. This feature can be
programmed on or off through the personal choice
selection menu. SeeDIC Vehicle Personalization on
page 3-51for programming instructions.
Outside Convex Mirror
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Automatic Dimming
Heated Mirror
If you have this feature, the outside driver’s mirror will
adjust for the glare of headlamps behind you. This
feature is controlled using the on and off settings on the
automatic dimming rearview mirror. SeeAutomatic
Dimming Rearview Mirror on page 2-32.
When you operate the rear window defogger, the
heated driver’s and passenger’s outside rearview mirrors
are warmed to help clear them of ice and snow. See
“Rear Window Defogger” underClimate Control System
on page 3-24orDual Automatic Climate Control
System on page 3-27for more information.
2-36

Vehicle Personalization
Memory Seat and Mirrors
If your vehicle has this feature, the controls are located
on the driver’s door panel, and are used to program
and recall memory settings for the driver’s seating,
outside mirror positions and climate controls.
SeeClimate Control System on page 3-24for
more information.To save your seat and mirror positions into memory,
use the following procedure:
1. First identify the DRIVER # on the Driver Information
Center (DIC) by pressing the MEMORY button 1
or 2 or by pressing the unlock button on the remote
keyless entry transmitter. SeeDriver Information
Center (DIC) on page 3-47.
2. Adjust the driver’s seat and lumbar position to a
safe and comfortable driving position. Adjust both
outside mirrors to suit you. SeeOutside Power
Mirrors on page 2-35.
3. Press and hold the MEMORY button (1 or 2)
corresponding with your DRIVER # displayed on the
DIC for longer than three seconds. You will hear
two beeps conrming that the seat and mirror
positions have been entered into memory.
To set the seat and mirror positions for a second driver,
follow the previous steps, but start by pressing the
unlock button on the transmitter that displays the other
DRIVER # on the DIC. Be sure to use the MEMORY
button which corresponds to the DRIVER # identied by
the second transmitter.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
TEMPERATURE:This lever is used to adjust the
temperature of the air coming through the system.
Moving the lever between COOL and WARM will change
the temperature of the air coming through your outlets.
9FAN:Move this lever to select the speed of
the fan. Moving the lever between LOW and HIGH will
decrease or increase the fan speed. The fan will be
off when the system is off.To change the current mode, select one of the following:
RECIRC (Recirculation):This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help heat or cool the air inside your vehicle more quickly.
Press this button to turn the recirculation mode on or
off. When the button is pressed, an indicator light
will come on. You cannot use RECIRC with FRONT
Defrost or BLEND.
VENT:This mode directs air to the instrument
panel outlets.
HTR (Heater):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
BLEND:This mode splits the airow between the
windshield and the oor outlets. The air conditioning
compressor will be operating.
OFF:The ventilation system always allows fresh air to
ow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.
3-24

Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle. This
information is then used to maintain the selected
temperature by initiating needed adjustments to the
temperature, the fan speed, and the air delivery system.
The system may also supply cooler air to the side of the
vehicle facing the sun. The recirculation mode will also be
activated, as necessary. Do not cover the solar sensor
located in the center of the instrument panel, near the
windshield, or the system will not work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. This mode allows you to clear fog or
frost from your windshield.
1FRONT (Defrost):Pressing this button directs
most of the air to the windshield and the outboard outlets
(for the side windows), with some air directed to the
oor outlets. In this mode, the system will automatically
turn off recirculation and run the air conditioning
compressor, unless the outside temperature is at or
below freezing. Recirculation cannot be selected while
in FRONT defrost mode. Do not drive the vehicle until all
the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
=REAR (Rear Window Defogger):Press this
button to turn the rear window defogger on or off. Be
sure to clear as much snow from the rear window
as possible.
At speeds above 35 mph (55 km/h), the defogger will
operate continuously until you press the REAR
button again. After 10 minutes of driving below 35 mph
(55 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for ve minutes
before going off by itself.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defogger
button is pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
