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:

Heated Seats
If your vehicle has heated
front seats, the buttons are
located on the climate
control panel.
There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI
and off. The active setting appears on the climate control
panel display. The LO setting warms the seatback
and cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.To turn on the heated seats, press the button once.
The seat will heat to the HI setting. Press the button
again to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press the
button again.

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.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
Trunk Lock Release
The remote trunk release
button is located on the
lower portion of the
driver’s door.
To use the remote trunk release, the shift lever must be
in PARK (P) or NEUTRAL (N) for a vehicle with an
automatic transmission. The shift lever must be
in NEUTRAL, with the parking brake set for a vehicle
with a manual transmission.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the Remote
Keyless Entry (RKE) transmitter to open the trunk.
If your vehicle is ever without power, you can still access
the trunk area. Use one of the following procedures to
manually open the trunk.
2-12

Running the Engine While 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 2-37.
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 4-27.
{CAUTION:
It can be dangerous to get out of your vehicle
if the automatic transmission shift lever is not
fully in PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave your
vehicle when the engine is running unless you
have to. If you have left the engine running,
the vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when it is on fairly level
ground, always set the parking brake and
move the automatic transmission shift lever to
PARK (P), or the manual transmission shift
lever to NEUTRAL.
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) (Automatic
Transmission) on page 2-34andParking Your Vehicle
(Manual Transmission) on page 2-36.
If you are parking on a hill and if you are pulling a
trailer, seeTowing a Trailer on page 4-39.
2-38

Outside Convex Mirror
{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.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so that more can be seen
from the driver’s seat. The mirror does not have
a dimming feature.
Outside Heated Mirrors
When the rear window defogger is turned on, it also
warms both outside rearview mirrors to help clear them
of fog or ice. See “Rear Window Defogger” under
Dual Climate Control System on page 3-23for more
information.
