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:

Liftgate (SUV)
{CAUTION:
It can be dangerous to drive with
the liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You can not see or smell CO.
It can cause unconsciousness and even
death. If you must drive with the liftgate
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
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.
SeeDual Automatic Climate Control
System on page 197.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 137.To lock and unlock the liftgate, use any of the
power door lock switches or the remote keyless
entry (RKE) transmitter.
To open the liftgate, do the following:
1. Move the spare tire carrier out of the way.
See “Opening the Spare Tire Carrier” under
Tailgate/Spare Tire Carrier on page 108.
2. Pull the handle located in the center of
the door.
To close the liftgate, do the following:
1. Pull the liftgate down until it latches.
2. Move the spare tire carrier back into place.
See “Closing the Spare Tire Carrier” under
Tailgate/Spare Tire Carrier on page 108.

Midgate®(SUT)
{CAUTION:
It can be dangerous to drive with the
cargo area covered and the tailgate and
the Midgate
®open because carbon
monoxide (CO) gas can come into your
vehicle. You can not see or smell CO.
It can cause unconsciousness and even
death. If you must drive with the cargo
covers on and the tailgate and Midgate
®
CAUTION: (Continued)
CAUTION: (Continued)
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the Midgate
®:
Make sure all windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
on the setting that brings in outside
air. This will force outside air into your
vehicle. SeeDual Automatic Climate
Control System on page 197.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 137.
The Midgate
®allows you to extend the length of
your vehicle’s cargo area into the cab.
105

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 137.
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 353.
{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).
138

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 more can be
seen from the driver’s seat. It makes things in the
mirror appear farther away than they really are.
Outside Heated Mirrors
If the vehicle has
heated mirrors, the
button to turn this
function on or off is
located on the climate
control panel.
Press this button to warm the driver’s and
passenger’s outside rearview mirrors to help clear
them of ice, snow, and condensation.
With a rear window defogger, the heated mirrors
will come on when this button is pressed. See
“Rear Window Defogger” underDual Automatic
Climate Control System on page 197for more
information.
