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:
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

iv

The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door while the security lock is engaged,
unlock the door and open the door from the outside.
Lockout Protection
This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver’s door will unlock.
Liftgate
{CAUTION:
It can be dangerous to drive with the liftgate
glass, liftgate or rear doors open because
carbon monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It can
cause unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftgate glass,
liftgate, or rear doors open, or if electrical
wiring or other cable connections must pass
through the seal between the body and the
liftgate glass, liftgate, or rear doors:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force
outside air into your vehicle. SeeClimate
Control System on page 3-22.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-35.
2-13

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
underEngine Exhaust on page 2-35.
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.
SeeWinter Driving on page 4-40.
{CAUTION:
It can be dangerous to get out of your vehicle
if the 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 you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P).
2-36

Outside Curb View Assist Mirrors
If the vehicle has the memory package, the outside
mirrors are able to perform the curb view assist mirror
function. This feature will cause the passenger’s
and/or driver’s mirror to tilt to a preselected position
when the vehicle is in REVERSE (R). This feature may
be useful in allowing the driver to view the curb when
parallel parking. When the vehicle is shifted out of
REVERSE (R) and a short delay has occurred,
the passenger’s and/or driver’s mirror will return to
its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory
as the tilt position.
This feature can be turned on or off through the Driver
Information Center (DIC). SeeDriver Information
Center (DIC) on page 3-52for more information.
Outside Convex Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved so you can see more 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 Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed,
the heated mirrors are also turned on. See “Rear
Window Defogger” underDual Automatic Climate
Control System on page 3-25orDual Climate Control
System on page 3-23for more information.
