{CAUTION:
It can be dangerous to drive with the liftgate
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 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. See “Climate Control
System” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust” in the Index.

instrument panel outlets, then directs the remaining
air to the oor outlets. Cooler air is directed to the upper
outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets. Use this mode to send air to the rear of the
vehicle. Keep the area under the front seats free of
objects that could obstruct airow to the rear of

System
Your vehicle may have the dual automatic climate
control system. With this system you can control the
heating, cooling, and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When the driver’s temperature
knob is pressed to select AUTO and the temperature is
set, the system will automatically control the inside
temperature, the air delivery and the fan speed. AUTO

do the following:
1. Press the driver’s temperature knob to turn the
system on.
2. Adjust the temperature to a comfortable setting.
Choosing the coldest or warmest temperature will

In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. Then, as the air warms,
it will be delivered through the instrument panel
outlets. The length of time needed for warm up will
depend on the outside temperature and the
length of time that has elapsed since your vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature as
necessary.
4. To turn the system off, press the passenger’s knob.

appears, so adjust your driving accordingly.
The message will stay on for a few seconds after the
traction control system stops limiting wheel spin.

stays on, you will be able to restart your engine if
you turn it off.
Your PASS-Key
®III system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS-Key
®III system at
this time. SeePASS-Key®III on page 2-17for more
information.
All-Wheel Drive Disable Warning
Message
Your vehicle may have this message. If it does, it will
come on when there is a spare tire on the vehicle, or
when the anti-lock brake system warning light comes on,
or when the rear differential uid is overheating. This
message will go out when the differential uid cools.
The all-wheel drive system will be disabled until the
compact spare tire is replaced by a full-size tire. If the
warning message is still on after putting on the full-size
tire, you need to reset the warning message. To reset the
warning message, turn the ignition off and then back on
again. If the message stays on, see your dealer right
away. SeeAll-Wheel Drive (AWD) System on page 4-12

To turn the system off,
press the TRAC OFF
button located on
the instrument panel
switchbank.
If the system is limiting wheel spin when you press the
button, the message will go off, but the system will not
turn off until there is no longer a current need to limit
wheel spin. The TRAC OFF light will come on to remind
you the system is off. You can turn the system back on at
any time by pressing the button again. The traction
control system warning message should go off.All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin to
slip, the rear wheels will automatically begin to drive
the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy AWD applications, the engine torque may
be reduced to protect AWD system components. If
the vehicle is exposed to extended heavy AWD usage,
the AWD system will shut itself off to protect the
system from overheating. When the system cools down,
the AWD system will activate itself again automatically;
this cool-down can take up to 20 minutes depending
on outside temperature and vehicle use. SeeAll-Wheel
Drive Disable Warning Message on page 3-55.
