Liftgate
To unlock the liftgate from the outside, turn the key in
the cylinder clockwise or use the optional remote
keyless entry. To lock the liftgate using the key, turn the
key counterclockwise.
Open the liftgate using the handle located above the
license plate. Once slightly opened, the liftgate will rise
by itself. Lamps in the rear of the vehicle will come on,
illuminating the rear cargo area. See ªInterior Lampsº in
the Index.
NOTICE:
Be sure there are no overhead obstructions, such
as a garage door, before you open the liftgate.
You could slam the liftgate into something and
break the glass.
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 with the setting
on vent and the outside air button pressed.
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.

AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35F (2C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
See ªComfort Controls, Heatingº in the Index for
more information.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer (so there is less shifting
between gears).

When going down a steep hill.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-114 Traction Active Message (Option)
United States Canada
If your vehicle has the traction control system, the
TRACTION ACTIVE message will appear when the
traction control system is limiting wheel spin. You may
feel or hear the system working, but this is normal.
Slippery road conditions may exist if this message
appears, so adjust your driving accordingly. The
message will stay on for a few seconds after the traction
control system stops limiting wheel spin.
Engine Coolant Temperature
Warning Message
United States Canada
This message will come on when your engine gets
too hot.
If this message comes on, it means that your engine
coolant has overheated. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road, stop your vehicle and turn off the
engine as soon as possible.
See ªEngine Overheatingº in the Index.

Comfort Controls
This section tells you how to make your air system work
for you.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has
a flow
-through ventilation system described later in
this section.
Fan Knob
The left knob is the fan knob and is used to select the
force of air you want. Turn the knob clockwise to
increase fan speed and counterclockwise to decrease fan
speed. The fan must be turned on for the air
conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it clockwise toward
the red area for warmer air. Turn it counterclockwise
toward the blue area for cooler air.
Mode Knob
The right knob is used to select the direction of the air
flowing into the vehicle.
(Vent): This setting directs air through the
instrument panel outlets.
(Bi-Level): This setting directs air into your
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the floor ducts.
(Floor): This setting brings in most of the air
through the floor ducts. This setting is also used to send
air to the rear of the vehicle. Keep the area under the
front seats free of objects that could obstruct airflow to
the rear of the vehicle.

3-3
(Defog): This setting directs air to the windshield
and through the floor ducts. This mode is useful during
cold or inclement weather because of your vehicle's
larger windshield area.
(Defrost): This setting directs most of the air to the
windshield and side window vents.
Mode Buttons
(Outside Air): Press this button to send outside
air into your vehicle. The light in the button will glow
when outside air is in use. Using this setting while trying
to defrost or defog the windows will help clear the vents
of moisture. While floor, defog or defrost mode is
selected, the system will automatically go to outside
air mode.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. The light in
the button will glow when outside air is in use. You may
use this setting to limit odors entering your vehicle.
Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the recirculation mode may cause
fogging of the vehicle's windows when the weather iscold and damp. To clear the fog, switch the HVAC
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-fogging of the windows,
operate the HVAC system in the outside air mode.
A/C (Air Conditioning): Press this button to turn
the air conditioning compressor on and off. The light in
the button will glow when the air conditioning is in use.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool
-down on
very hot days, press the A/C and recirculation buttons
and turn the temperature knob counterclockwise toward
the blue area. Adjust the mode knob to direct the air to
the desired location. This setting should not be used for
long periods of time because the air may become too
cold and dry. Push the A/C button again the to turn off
the air conditioning.

3-4
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.
Heating
Turn the temperature knob clockwise toward the red
area to warm the air.
In the floor mode, outside air will be brought in and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results, turn the temperature control knob to
the middle position, and then adjust it for comfort.Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
If you have the optional engine coolant heater and use it
during cold weather, 0
F (
-18
C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, turn the temperature
control knob all the way clockwise to the red area and
turn the mode knob to defrost. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the floor ducts, turn the mode knob to defog.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
