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.
If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor air
outlets for a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most normal
conditions.If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, FRONT DEFROST will
change to auUse only household glass cleaner and a soft
cloth. Wipe gently and dry throughly.tomatic operation
when the ignition is shut off and then turned back on.
Manual Operation
You may manually adjust the air delivery mode or fan
speed.
AC: This setting directs airflow through the four
instrument panel outlets.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
HEATER/DEFROST: This setting directs air to
the floor outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.

3-43 Radio Personalization with Home and Away
Feature (If Equipped)
If DRIVER 1 (HOME or AWAY) PRESETS or
DRIVER 2 (HOME or AWAY) PRESETS appears in the
display when the radio is first turned on, your vehicle is
equipped with this feature.
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings. The settings
recalled by the radio are determined by which RKE
transmitter (ª1º or ª2º) was used to enter the vehicle.
The number on the back of the RKE transmitter
corresponds to driver 1 or to driver 2. The radio settings
will automatically adjust to where they were last set
by the identified driver. The settings can also be recalled
by briefly pressing the MEMORY seat buttons 1 or
2 located on the driver's door.
Your radio can store home and away presets. Home and
away presets allow you to use one set of preset radio
settings in the area where you live, and another set when
you go out of town. That way, you will not need to
reprogram your presets every time you travel. With the
radio off and the clock displayed, use FF and RW to
select home or away presets. To select the away presets,
press and hold FF for five counts until you hear a beep.The next time the radio comes on, the away presets will
be active. To select the home presets, press and hold RW
for five counts until you hear a beep. The next time the
radio comes on, the home presets will be active.
When battery power is removed and later applied, you
will not have to reset your home radio presets because
the radio remembers them. However, you will have to
reset your away radio presets.
Theft-Deterrent Feature
THEFTLOCK
is designed to discourage theft of your
radio. Your vehicle has a ªbuilt
-inº theft-deterrent
feature on each radio that is automatic
-- there is no
programming required. The radio in your vehicle cannot
be used in any other vehicle. When the radio was
originally installed in your vehicle at the factory, it
stored the Vehicle Identification Number (VIN). Each
time the ignition is turned on, the VIN is verified. If the
vehicle's VIN does not match the VIN stored in the
radio, THEFTLOCK will be activated and the audio
system will not play. If the radio is removed from your
vehicle, the original VIN in the radio can be used to
trace the radio back to your vehicle.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.

4-35
Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull a trailer only if you have followed all the
steps in this section. Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That's the reason for this part. In it are many
time
-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load
-pulling components such as the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What's more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.

4-36 If You Do Decide To Pull A Trailer
If you do, here are some important points:

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you'll be driving. A good source for this
information can be state or provincial police.

Consider using a sway control if your trailer will
weigh 2,000 lbs. (900 kg) or less. You should always
use a sway control if your trailer will weigh more
than 2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.

Don't tow a trailer at all during the first 1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.

Then, during the first 500 miles (800 km) that you
tow a trailer, don't drive over 50 mph (80 km/h) and
don't make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.

Obey speed limit restrictions when towing a trailer.
Don't drive faster than the maximum posted speed
for trailers (or no more than 55 mph (90 km/h)) to
save wear on your vehicle's parts.Three important considerations have to do with weight:

the weight of the trailer,

the weight of the trailer tongue

and the total weight on your vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 2,000 lbs. (900 kg)
without the optional trailer towing package. If you have
the optional trailer towing package, the maximum trailer
weight should never be more than 3,000 lbs. (1 350 kg).
These are total maximum weights including the load.
But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle.

4-37
The optional trailer towing package provides the
necessary oil cooler to tow a trailer heavier than
2,000 lbs. (900 kg).

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total or gross
weight of your vehicle. The Gross Vehicle Weight
(GVW) includes the curb weight of the vehicle, any
cargo you may carry in it, and the people who will be
riding in the vehicle. And if you tow a trailer, you must
add the tongue load to the GVW because your vehicle
will be carrying that weight, too. See ªLoading Your
Vehicleº in the Index for more information about your
vehicle's maximum load capacity.

4-39 Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer's recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Because you have anti-lock brakes, don't try to tap into
your vehicle's hydraulic brake system. If you do, both
brake systems won't work well, or at all. If you tow
more than 1,000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from the brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes so you'll be able to maintain them properly.
Trailer Wiring Harness (Option)
If your vehicle is equipped with the trailer towing
package, your vehicle has additional wiring to attach
to a trailer's wiring harness. Contact your dealer for
proper installation.
