Power Lumbar
If your vehicle has this
feature, the power lumbar
control is located on
the outboard side of each
front seat.
Use the
power seat control first to
get the proper position.
Then continue with the lumbar adjustment.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support. Press the control up or down to raise
or lower the support mechanism.
Keep in mind that as your seating position changes, as
it may during long trips,
so should the position of
your lumbar support. Adjust the seat as needed.
If you have the independent front cushion moved down
as
far as it will go, you may feel the lumbar support
higher in your back. Readjust the location of the cushion
until you are comfortable. You may also want to
adjust the seatback for maximum comfort.
Heated Seats
If your vehicle has this
option, the heated front
seat controls are located
on the instrument panel under the climate
controls.
Push
ON once for the HI setting or twice for the LO
setting. The lights above the button will come on
to indicate which setting has been activated. Push
OFF
to turn the heated seat off. The LO setting warms
the seatback and cushion until the seat approximates
body temperature. The
HI setting heats the seatback
and cushion to a slightly higher temperature.
The heated seats can only be used when the ignition is
turned on. The heating elements in the seats
automatically turn
off when the vehicle’s ignition is
turned
off.

TEMP (Temperature Control): Turn the right knob
clockwise or counterclockwise to manually increase or
decrease
the temperature inside your vehicle,
To change the current mode, select one of the following:
(FLOOR): This mode directs most of the air to
the floor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed
to the windshield.
li;' (Bi-Level): This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most
of the remaining air to the floor outlets.
There is also a small amount of air directed to the
windshield and outboard outlets (for the side windows).
This mode directs cooler air to the upper outlets and
warmer air to the floor outlets.
f;' (Vent): This mode directs air io th2 imtr~ment
panel outlets.
(Recirculation): This mode keeps outside air
from coming in the vehicle.
It can be used to prevent
outside air and odors from entering your vehicle or

Automatic Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic): Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button. Whenever this button is
pressed, the display will show the current settings
for five seconds before returning the display to
the exterior temperature.
2. Adjust the temperature to 75” F (24” C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster.
If you set the system at the warmest
temperature setting, the system will remain at the
maximum heat setting and fan speed.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the floor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. 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, if
necessary.
Do not cover the solar sensor located in the center OT
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.

The optional Traction Control System is active and
is limiting wheel spin. You may feel the system
working, but this is normal. Slippery road conditions
may exist,
so adjust your driving accordingly.
If the LOW TRAC light comes on, slippery road
conditions may exist,
so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage

Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down to
THIRD (3) and
reduce your speed to around 45 mph
(70 km/h) to
reduce the possibility
of the engine and transaxle
overheating.
Parking on Hills
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 don’t shift into

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule 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.
Each of these is covered in this manual, and the
Index will help you find them quickly.
If you’re trailering,
it’s a good idea to review this information before you
start your trip.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See
Engine Overheating on
page 5-29.
Check periodically to see that all hitch nuts and bolts
are tight.
