Automatic climate control
system
NOTE y
Operate the automatic climate con-
trol system when the engine is run-
ning. y The blower fan rotates at a low speed
when the engine coolant temperature
is low.
For efficient defogging or dehumidify-
ing in cold weather, press the “A/C”button. y Even when cooling is not necessary,
setting the temperature much lower
than the current outlet air temperature
turns on the air conditioner compres-
sor automatically and the “A/C” indica-
tor light on the control panel comes on.y Seven-seater models each have a
rear air conditioner. The fan speed of
the rear air conditioner can be adjust-
ed, but other adjustments (outlet air
temperature, air distribution, etc.) are
not possible for the rear air condition-
er. For details, refer to “Rear air condi-
tioner (if equipped)” in this section.
The automatic climate control system au-
tomatically controls outlet air temperature,
fan speed, air flow distribution air-inlet
control, and air conditioner compressor operation. It activates when the “AUTO”
button is pressed, and is used to maintain
a constant, comfortable climate within the
passenger compartment.
The temperature can be set within a range
of 65 to 85
°F (18 to 32 °C).

Temperature control dial
Driver’s side
Passenger’s side
It is possible to make separate tempera- ture settings for the driver’s side and pas-
senger’s side. Each temperature setting is
shown on the display. With the dial set at
your desired temperature, the system au-
tomatically adjusts the temperature of air
supplied from the outlets such that the de-
sired temperature is achieved and main-
tained.
Turning the dial counterclockwise and re-
leasing it reduces the temperature by 1
°F
(0.5 °C). Turning the dial clockwise and re-
leasing it increases the temperature by1 °F (0.5 °C). Holding the dial in either
turned position causes the temperature to
change continuously.
With the minimum temperature set, the
system gives maximum cooling perfor-
mance. With the maximum temperature
set, the system gives maximum heating
performance.

Operating tips for heater and
air conditioner „Cleaning ventilator grille
Always keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept
clean because cooling performance is im-
paired by any accumulation of insects and
leaves on the condenser. „ Efficient cooling after parking
in direct sunlight
After parking in direct sunlight, drive with
the windows open for a few minutes to al- low outside air to circulate into the heated
interior. This results in quicker cooling by
the air conditioner. Keep the windows
closed during the operation of the air con-
ditioner for maximum cooling efficiency. „
Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil. „ Checking air conditioning
system before summer sea-son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper op-
eration each spring. Have your SUBARU
dealer perform this check. „ Cooling and dehumidifying in
high humidity and low tem-
perature weather condition
Under certain weather conditions (high
relative humidity, low temperatures, etc.)
a small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate any problem with the air conditioning sys-
tem. „
Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed to temporarily shut off during air
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration or when driving on a
steep upgrade. „ Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the
method of adding, changing or checking
the refrigerant is different from the method
for CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.

Trailer hitch (if equipped)
1) Trailer hitch
The trailer hitch is designed to tow a Class
1 rated load. The maximum gross trailer
weight and maximum gross tongue weight
are indicated in the following table. When you tow a trailer, follow the instruc-
tions in the next section “Trailer towing”. „
Connecting a trailer
1. Remove the receiver cover from the
hitch receiver tube. Then insert the ball
mount into the hitch receiver tube.
2. Insert the hitch pin into the hole on the
y Never exceed the maximum
weight specified for the trailer
hitch. Exceeding the maximum
weight could cause an accident
resulting in serious personal inju-
ries. Permissible trailer weight
changes depending on the situa-
tion. Refer to the next section
“Trailer towing” for possible rec-
ommendations and limitations.

yTrailer brakes are required when
the towing load exceeds 1,000 lbs
(453 kg). Be sure your trailer has
safety chains and that each chain
will hold the trailer’s maximum
gross weight. Towing trailers
without safety chains could create
a traffic safety hazard if the trailer
separates from the hitch due to
coupling damage or hitch ball
damage.
yBe sure to check the hitch pin and
safety pin for positive locking
placement before towing a trailer.
If the ball mount comes off the
hitch receiver, the trailer could get
loose and create a traffic safetyhazard.
yUse only the ball mount supplied
with this hitch. Use the hitch only
as a weight carrying hitch. Do not
use with any type of weight dis-
tributing hitch.

Gross Vehicle Weight Rating (GVWR)
Gross Vehicle Weight
The Gross Vehicle Weight (GVW) must
never exceed the Gross Vehicle Weight
Rating (GVWR).
Gross Vehicle Weight (GVW) is the com-
bined total of the weight of the vehicle,
driver, passengers, luggage, trailer hitch,
trailer tongue load and any other optional
equipment installed on your vehicle.
Therefore, the GVW changes depending
on the situation. Determine the GVW each
time before going on a trip by putting your
vehicle and trailer on a vehicle scale.

1) Jack
2) Bathroom scale
The tongue load can be weighed with a
bathroom scale as shown in the following
illustration. When weighing the tongue
load, be sure to position the towing cou-
pler at the height at which it would be dur-
ing actual towing, using a jack as shown. F: Front
The tongue load can be adjusted by prop-
er distribution of the load in the trailer.
Never load the trailer with more weight in
the back than in the front; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as even-
ly as possible on both the left and rightsides.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving. „

Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your ve-
hicle and cause corrosion around
the drilled hole. y
Do not modify the vehicle exhaust
system, brake system, or other
systems when installing a hitch or
other trailer towing equipment.
y Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
