Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't 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 weren't done correctly.

Your vehicle or exhaust system had been
modified 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 fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if
ever you 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
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch 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 ªBlizzardº in the Index.)

2-30
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 firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.
All-Wheel Drive (Option)
If your vehicle has
all
-wheel drive, your
engine's driving power is
sent to all four wheels for
extra traction when needed.
This is like four
-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for
road conditions.

2-32 Swing-Out Windows
To open your swing-out
windows, pull up on
the latch and push the
window out.
To close the window, pull the latch toward you and
push it down.CAUTION:
It can be dangerous to drive with the rear
swing
-out windows, rear hatch or rear doors
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the rear swing-out
windows, rear hatch or rear doors open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
rear swing
-out windows, rear hatch 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 setting
on anything but MAX A/C. That will force
outside air into your vehicle. See ªComfort
Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

center of the engine cover. To open the compartment,
press the two tabs together and pull.
If you have an optional sliding tray storage compartment,
it is under the front passenger's seat. To open the
compartment, move the latch in the top handle and
pull the tray forward.

to open the cover.There is also a map/storage pocket on the passenger's

2-52
Don't exceed the maximum vehicle capacity when loading
your vehicle. For more information on vehicle capacity
and loading, see ªLoading Your Vehicleº in the Index.
To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage carrier
and cargo are still securely fastened.
Ashtrays and Cigarette Lighter
The cigarette lighter is on the left of the engine
cover console.
To use the lighter, press it in all the way and let go.
When it's done heating, it will pop back by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
NOTICE:
When using the cigarette lighter as an accessory
power outlet, maximum electrical load must not
exceed 20 amps. Always turn off any electrical
equipment when not in use. Leaving electrical
equipment on for extended periods will drain
your battery.
The front ashtray is just above the passenger's side
front cupholder.
To remove the front ashtray, open it and gently pull
it slightly past its stop.
To remove the ashtray on the sliding door, open it,
press down on the inside tab and pull out.
You may have another ashtray on the driver's sidewall.
Press the right side to turn the ashtray around for use.
To remove the ashtray, open it and gently pull it off
the hinge.

2-53
NOTICE:
Don't put papers and other things that burn
into your ashtrays. If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them from side to side. Your visors may
have an extension that can be pulled out for additional
glare protection and a strap for holding small items,
such as maps.
Visor Vanity Mirror (If Equipped)
Some visors have mirrors built in, with or without
lamps. Just lift the mirror cover on each visor to turn
the lamps on, if you have them.
Accessory Power Outlets
You can plug auxiliary electrical equipment into accessory
power outlets. Just pull up from the bottom of the door
and follow the proper installation instructions that are
included with any electrical equipment that you install.
Two accessory power outlets are located on the
passenger's side of the engine cover.
Another accessory power outlet is located on the driver's
side behind the third row seating position, near the floor.
These circuits are protected by a fuse and have maximum
current levels.
NOTICE:
When using the accessory power outlets, maximum
electrical load must not exceed 25 amps. Always
turn off any electrical equipment when not in use.
Leaving electrical equipment on for extended
periods will drain your battery.

Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold
down the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want
to program. Hold the end of the hand
-held
transmitter about 2 to 5 inches (5 to 13 cm) away
from the surface of the HomeLink Transmitter so
that you can still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the red
light on the HomeLink Transmitter flash rapidly.
The rapid flashing indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand
-held transmitter is not dead. If you still cannot
program it, rotate the hand
-held transmitter end over
end and try again. The HomeLink Transmitter may not
work with older garage door openers that do not meet
current Federal Consumer Safety Standards. If you
cannot program the transmitter after repeated attempts,
refer to ªTraining a Garage Door Opener with Rolling
Codesº later in this section or contact the manufacturer
of the unit at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.
Note to Canadian Owners: During programming,
the hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.
