CAUTION:
It can be dangerous to drive with the tailgate
glass, tailgate 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 tailgate glass, tailgate
or rear doors open or if electrical wiring or other
cable connections must pass through the seal
between the body and the tailgate glass, tailgate
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 VENT. 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.
Tailgate Glass and Tailgate
If your vehicle has a tailgate, you must raise the rear
glass before lowering the tailgate.
To open the glass from the outside, use your key. With
the key in the lock, turn the key clockwise to release the
glass, then lift it up.
To release the glass from the inside, use the electric
tailgate glass release switch on the instrument panel. For
more information, see ªTailgate
-- Electric Glass
Releaseº in the Index.
To open the tailgate, lift up on the handle while pulling
the tailgate toward you.
Close the tailgate before closing the rear glass. After
closing the tailgate, make sure the tailgate is securely
latched by pulling it toward you. After closing the rear
glass, pull up on its handle to make sure it is locked.
Panel Doors
To open the rear panel doors, you must open the
passenger's side panel door first. If the door is locked,
insert your door key in the lock and turn it
counterclockwise to unlock it.

To open the driver's side panel door, first open the
passenger's side door. Then, pull the handle on the left
door edge out and pull the door open.
The rear doors have a check assembly to keep them
from fully opening during normal use.
To fully open either rear door, you must release the
check strap. To release the check strap just:
1. Open the door partway until the white mark on the
check strap is fully outside the door edge. If the end
of the strap catches the pin on the door, the door is
open too far.
2. Then, hold the strap at
the white mark, pull the
strap toward you and
open the door all
the way.
To r e
-engage the door check strap, just close the door
and the strap will catch the pin.To close the doors, close the driver's side door first.
After securely closing the door, close the passenger's
side door. Make sure both doors are latched securely.
To lock the rear doors from outside the vehicle, put your
key in the lock and turn it clockwise. If you have power
door locks, you can lock the side doors as well as the
rear doors from inside the vehicle. For more
information, see ªPower Door Locksº in this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. Also remember to lock
the doors.

Rear Air Conditioning and Rear Heater
(If Equipped)
If your vehicle has the rear air conditioning and rear
heater system combination, controls are provided to
regulate temperature, location and speed of the airflow.
To adjust the airflow speed, turn the fan control
knob on the left side of the control panel to the desired
blower setting.
To activate the rear control, move the fan knob on the
front control to REAR CNTL.To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob clockwise for floor
vent airflow or counterclockwise for headliner vent
airflow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the air temperature, turn the temperature knob
on the right of the control panel.
For warmer air, turn the knob clockwise to the red, and
for cooler air, turn the knob counterclockwise.
The rear control works just like the front control. It will
allow second seat passengers to adjust the controls as
they desire.

3-7 Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The recirculation button, between the fan and
temperature knobs, allows the air inside your vehicle to
be recirculated. This setting helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fastest and
can be used to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner,
turn off recirculation after the vehicle reaches a
comfortable interior temperature. When the right knob
on the control panel is between HEATER and
DEFROST, the recirculation feature will not function.
The A/C button, between the temperature and mode
knobs, allows the air coming into your vehicle to be
cooled. This setting is useful for normal cooling on hot
days. When you use A/C with the recirculation button
pushed in, turn off recirculation as soon as the vehicle
reaches a comfortable interior temperature.With the A/C on, move the temperature knob to MAX
for maximum cooling. This setting also puts the system
in the recirculation mode and helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fastest. After
the vehicle's interior reaches a comfortable temperature,
move the temperature knob clockwise to place the air
conditioning system in the normal mode.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the HEATER or
VENT/HEAT setting with the temperature knob in the
red area.
If you use the engine coolant heater before starting your
engine in cold weather, 20
F (
-8
C) or lower, your
heating system will produce warmer air faster, to heat
the passenger compartment in cold weather.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature, and shortens the time it takes the heater to
reach full output. For more information, see ªEngine
Coolant Heaterº in the Index.
