Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
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 trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid.

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on AUTO and the temperature between
65F (18C) and 85F (29C). 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.
Trunk Lock Release
To use this feature,
your vehicle must
be in PARK (P) or
NEUTRAL (N) and the
VALET lockout button
must be in OFF. Press the
TRUNK button, located
above the radio on the
Driver Information Center
(DIC), to open the trunk.
You can also press the trunk button on the
remote keyless entry transmitter to access the
trunk compartment.

If this message appears and stays on while driving or
after starting your vehicle, have it checked immediately
to determine the cause of this problem. To help the
generator recharge the battery quickly, you can reduce
the load on the electrical system by turning off the
accessories. You can monitor battery voltage on the
DIC by pressing the INFO (SKIP) button. The normal
range is 11.5 to 15.5 volts.
CHANGE ENGINE OIL
- 82: This means that the
life of the engine oil has expired and it should be
changed within 200 miles (322 km). See ªEngine Oilº
and ªFilter Recommendationsº in the Maintenance
Schedule booklet. After an oil change, the Oil Life
Indicator must be reset. See ªOil Life Indicator, How to
Resetº in the Index.
CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CHECK BRAKE FLUID LEVEL
- 37: This message
will display if the ignition is in RUN to inform the
driver that the brake fluid level is low. Have the brake
system serviced by a technician as soon as possible.
See ªBrake System Warning Lightº in the Index.CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAUGE
- 39: This message will
appear when the fuel supply is less than 3.5 gallons
(13.2 L) remaining. A single chime will also sound
when this message is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's fully tightened.
CHECK OIL LEVEL
- 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure the engine has been off for
five minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See ªEngine
Oilº in the Index.

Comfort Controls
This section tells you how to make your air system
work for you.
With the ECC 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.
Climate Control Panel
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.Driver's Side Temperature Knob
The TEMP/AUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Press the TEMP/AUTO knob to put the system
in the automatic mode.
Passenger's Side Temperature Button
With this dual
-zone feature, the right front passenger
can control the temperature of air for his/her own zone.
The passenger can select a four degree warmer or cooler
temperature from the driver's setting. To turn the system
on, press the PASS/TEMP button. Press the up arrow

The outside temperature sensor is located near the
front grille. The sensor can be affected by road or
engine heat during idling, slow driving or when the
engine is first started after a short trip. In order to
ensure proper automatic climate control operation,
the outside air temperature display may not update as
quickly as expected. This is to allow the air surrounding
the outside temperature sensor to be as close to the
actual outside conditions as possible. This is determined
by how much time has elapsed since the vehicle has
been turned off and by vehicle speed.
Mode Button
Press the MODE button to deliver air through the floor,
middle or windshield outlets. The system will stay in the
selected mode until the MODE button is pressed again.
Press the up or down arrow to cycle through the
available modes.
Automatic Operation
When the system is set for automatic operation,
sensors will control the air delivery mode. Air will
come from the floor, middle or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP/AUTO knob to adjust the
temperature if necessary. If you choose 60
F (16
C),
the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose
the temperature of 90
F (32
C), the system will
remain at that maximum heating setting and will not
regulate fan speed. Choosing either maximum setting
will not cause the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the
need for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-level mode).
On bright sunny days in cold weather, the airflow may
come out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

When you enter a vehicle in cold weather, adjust the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. SeeªAudio
Steering Wheel Controlsº
in the Index.
FAN SPEED: Press the up arrow lever to
increase the fan speed and the down arrow lever to
decrease fan speed.
TEMP: Press the up arrow lever to increase
the temperature and the down arrow lever to
decrease temperature.

4-24
If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid levels
and also the brakes, tires, cooling system and transaxle.
These parts can work hard on mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
CAUTION:
If you don't shift down, your brakes could
get so hot that they wouldn't work well. You
would then have poor braking or even none going
down a hill. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.

Stay in your own lane when driving on two
-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.

As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.

You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no
-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.

4-37 Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift
into PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brake.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet for
more on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belt, cooling system and brake system.
If you're trailering, it's a good idea to review this
information before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.
