In case the trailer hitch connector or hitch ball should break or
become disconnected, the trailer could get loose and create a traffic
safety hazard.
For safety, always connect the towing vehicle and trailer with trailer
safety chains. Pass the chains crossing each other under the trailer
tongue to prevent the trailer from dropping onto the ground in case
the trailer tongue should disconnect from the hitch ball. Allow suffi-
cient slack in the chains taking tight-turn situations into account; how-
ever, be careful not to let them drag on the ground.
For more information about the safety chain connection, refer to the
instructions for your hitch and trailer. n
Side mirrors
After hitching a trailer to your vehicle, check that the standard side
mirrors provide a good rearward field of view without significant blindspots. If significant blind spots occur with the vehicle ’s standard side
mirrors, use towing mirrors that conform with Federal, state/province
and/or other applicable regulations.

n Trailer lights CAUTION
Direct splicing or other improper connection of trailer lights may
damage your vehicle ’s electrical system and cause a malfunction
of your vehicle ’s lighting system.

8-36Connection of trailer lights to your vehicle
’s electrical system requires
modifications to the vehicle ’s lighting circuit to increase its capacity
and accommodate wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU dealer. Check for
proper operation of the turn signals, the brake lights and parkinglights each time you hitch up. n Tires
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated. OUTBACK: The recommended cold tire pressure under trailer
towing conditions is indicated on the tire placard located under thedoor striker on the driver ’s side. Adjust the rear tire pressure to the
recommended pressure shown on the tire placard when the tires
are cold. Normal pressure should be maintained in the front tires.Other models: It is recommended to inflate the rear tires to 3 psi
(20 kPa, 0.2 kg/cm 2
) above their normal operating pressure when
the tires are cold. Normal pressure should be maintained in the
front tires.
Trailer tire condition, size, load rating and proper inflation pressure
should be in accordance with the trailer manufacturer ’s specifications.
In the event your vehicle gets a flat tire when towing a trailer, ask a
commercial road service to repair the flat tire.
If you carry a regular size spare tire in your vehicle or trailer as a pre-
caution against getting a flat tire, be sure that the spare tire is firmly
secured.

Trailer towing tips CAUTION
Never exceed 45 mph (72 km/h) when towing a trailer in hilly
country on hot days. When towing a trailer, steering, stability, stopping distance and
braking performance will be different from normal operation. For
safety’ s sake, you should employ extra caution when towing a
trailer and you should never speed. You should also keep the fol-lowing tips in mind:
n Before starting out on a trip
Check that the vehicle and vehicle-to-hitch mounting are in good
condition. If any problems are apparent, do not tow the trailer. Check that the vehicle sits horizontally with the trailer attached. If
the vehicle is tipped sharply up at the front and down at the rear,
check the total trailer weight, GVW, GAWs and tongue load again,
then confirm that the load and its distribution are acceptable. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected properly. Confirm
that. –the trailer tongue is connected properly to the hitch ball.
– the trailer lights connector is connected properly and trailer ’s
brake lights illuminate when the vehicle ’s brake pedal is pressed,
and that the trailer ’s turn signal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected properly.
– all cargo in the trailer is secured safety in position.
– the side mirrors provide a good rearward field of view without a
significant blind spot.
Sufficient time should be taken to learn the “feel” of the vehicle/
trailer combination before starting out on a trip. In an area free of traf-
fic, practice turning, stopping and backing up.

Driving with a trailer
You should allow for considerably more stopping distance when
towing a trailer. Avoid sudden braking because it may result in skid-
ding or jackknifing and loss of control. Avoid abrupt starts and sudden accelerations. If your vehicle has a
manual transmission, always start out in first gear and release the
clutch at moderate engine revolution. Avoid uneven steering, sharp turns and rapid lane changes.
Slow down before turning. Make a longer than normal turning
radius because the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. In a tight turn, the trailer could hit yourvehicle. Crosswinds will adversely affect the handling of your vehicle and
trailer, causing sway. Crosswinds can be due to weather conditions or
the passing of large trucks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradually. When passing other vehicles, considerable distance is required
because of the added weight and length caused by attaching the
trailer to your vehicle. Backing up with a trailer is difficult and takes practice. When back-
ing up with a trailer, never accelerate or steer rapidly. When turning
back, grip the bottom of the steering wheel with one hand and turn it
to the left for a left turn, and turn it to the right for a right turn.

Driving on grades
Before going down a steep hill, slow down and shift into lower gear
(if necessary, use 1st gear) in order to utilize the engine braking effect
and prevent overheating of your vehicle ’s brakes. Do not make sud-
den downshifts. When driving uphill in hot weather, the air conditioner may turn off
automatically to protect the engine from overheating. When driving uphill in hot weather, pay attention to the water tem-
perature gauge pointer (for all vehicles) and AT OIL TEMP warning
light (for AT vehicles) since the engine and transmission are relatively
prone to overheating under these conditions. If the water temperature
gauge pointer approaches the OVERHEAT zone or the AT OIL TEMP
warning light illuminates, immediately switch off the air conditioner
and stop the vehicle at the nearest safe place. Refer to the “Engine
overheat” section in chapter 9, and “Warning and indicator lights ”
section in chapter 3. If your vehicle has an automatic transmission, avoid using the
accelerator pedal to stay stationary on an uphill slope instead of usingthe parking brake or foot brake. That may cause the transmission fluidto overheat. Also, if your vehicle is equipped with an automatic trans-mission, avoid driving with the gear selector lever in “D” when towing
a heavy trailer to prevent fluid overheating. A lower gear should beused. n Parking on a grade
Always block the wheels under both vehicle and trailer when parking.
Apply the parking brake firmly. You should not park on a hill or slope.But if parking on a hill or slope cannot be avoided, you should takethe following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both the vehicle and
trailer wheels.
3. When the wheel blocks are in place, release the regular brakes
slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the parking brake; slowly

Temporary spare tire
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle and may leadto an accident.
CAUTION
Never use any temporary spare tire other than the original. Usingother sizes may result in severe mechanical damage to the drivetrain of your vehicle.
The temporary spare tire is smaller and lighter than a conventional tire
and is designed for emergency use only. Remove the temporary spare
tire and re-install the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare tire periodically to
keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2
kg/cm 2
).
When using the temporary spare tire, note the following: Do not exceed 50 mph (80 km/h).
Do not put a tire chain on the temporary spare tire. Because of the
smaller tire size, a tire chain will not fit properly. Do not use two or more temporary spare tires at the same time.
Do not drive over obstacles. This tire has a smaller diameter, so
road clearance is reduced. When the wear indicator appears on the tread, replace the tire.

Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high tempera-
tures, or used for heavy-duty applications such as towing a trailer, use
of oil with the following grade and viscosities is recommended.
API classification SL (or SJ): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically

Abnormally high tire pressure (tread worn in center)
HSB013AA
Ride comfort is poor. Also, the tire magnifies the effects of road-sur-
face bumps and dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for the vehicle when fully loaded
and for the vehicle when towing a trailer, adjust the tire pressures to the
values that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould lead to an accident.
Wheel balance
Each wheel was correctly balanced when your vehicle was new, but the
wheels will become unbalanced as the tires become worn during use.
Wheel imbalance causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle ’s straight-line stability. It
can also cause steering and suspension system problems and abnormal
tire wear. If you suspect that the wheels are not correctly balanced, have
them checked and adjusted by your SUBARU dealer. Also have them
adjusted after tire repairs and after tire rotation.
