Lockout Protection
This feature stops the power door locks from locking
when the key is in the ignition and a door is open
to protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock
and then the driver’s door will unlock.
Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the
liftgate or liftglass 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 open or if
electrical wiring or other cable connections
must pass through the seal between the body
and the liftgate or liftglass:
Make sure all other windows are shut.
Turn the fan on your climate control
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 2-36.
Liftgate Release
To unlock the liftgate, use the power door lock switch or
the remote keyless entry transmitter. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5. The
liftglass will also unlock when the liftgate is unlocked.
Press the button on the liftglass to open it. To open the
entire liftgate, lift the handle located in the center of
the liftgate. When the liftgate is opened, the liftglass will
lock after a short delay.
2-11

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:
The 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 the exhaust system has
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 the Vehicle 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 2-36.
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.
Also see “If You Are Caught in a Blizzard”
underWinter Driving on page 4-29.

Outside Curb View Assist Mirror
If the vehicle has this feature, the passenger’s outside
mirror will adjust to a preset tilt position while the vehicle
is in REVERSE (R) gear. Curb view assist may be
useful when you are parallel parking. The mirror
will return to normal position when the vehicle is shifted
out of REVERSE (R) gear. Automatic mirror movement
in either direction will follow a short delay.
You may be able to turn this feature on or off through
the Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-58.
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 side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat. It also makes things, like other vehicles,
look farther away than they really are.
Outside Heated Mirrors
If the vehicle has this feature, when the rear window
defogger is turned on, the outside driver’s and
passenger’s rearview mirrors also heat to help clear
them of ice, snow, and condensation. SeeDual Climate
Control System on page 3-21orDual Automatic
Climate Control System on page 3-24for more
information.

A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-53.Battery Run-Down Protection
This feature shuts off the dome, courtesy, and vanity
lamps if they are left on for more than 20 minutes
when the ignition is off. This will keep the battery from
running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to RUN.
This feature will also turn off the parking lamps and
headlamps under most circumstances, if they are left on.
If you would like to turn them back on, turn the exterior
lamps knob.
3-19

Accessory Power Outlet(s)
With the accessory power outlets, you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has three accessory power outlets.
There are two outlets located below the climate controls
and one outlet is on the rear of the center oor console.
Remove the cover from the outlet to use the outlet.
Be sure to put the cover back on when not using the
accessory power outlet.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adaptor fuses. If you experience a
problem, see your dealer for additional information
on the accessory power outlets.Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
3-20

Ashtray(s) and Cigarette Lighter
Your vehicle may have this feature. The ashtray is
removable and ts into the front cupholder.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.
To remove the ashtray, pull the covered bin out of the
cupholder.
To use the lighter, press it in all the way, and let go.
When it is ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not use
equipment exceeding maximum amperage rating
of 20 amperes.
Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is in off mode, outside air still enters the
vehicle, and is directed based on the position of
the mode knob. The temperature can still be adjusted
using the temperature knob.
