Gross Axle Weight (GAW) and Gross Axle Weight Rating
(GAWR)
The total weight applied to each axle (GAW) must never exceed the
Gross Axle Weight Rating (GAWR). The front and rear GAWs can be
adjusted by relocating passengers and luggage inside the vehicle.
The front and rear GAWR are also shown on the certification label.
HBF019BB
Gross Axle Weight
OM-H2784
To check both GVWR and GAWR and to confirm that the total weight
and weight distribution are within safe driving limits, you should have
your vehicle and trailer weighed at a commercial weighing station.
Be sure that all cargo is firmly secured to prevent a change in weight
distribution while driving. nTongue load
WARNING
If the trailer is loaded with more weight in the back of trailer ’s
axle than in the front, the load is taken off the rear axle of the tow- ing vehicle. This may cause the rear wheels to skid, especiallyduring braking or when vehicle speed is reduced during corner-
ing, resulting in over-steer, spin out and/or jackknifing.
Ensure that the trailer tongue load is from 8 to 11 percent of the total
trailer weight and does not exceed the maximum value of 200 lbs (90kg).
The tongue load can be weighed with a bathroom scale as shown in

Trailer hitches
WARNING
Never drill the frame or under-body of your vehicle to install a
commercial trailer hitch. If you do, dangerous exhaust gas, wateror mud may enter the passenger compartment through the drilledhole. Exhaust gas contains carbon monoxide, a colorless andodorless gas which is dangerous, or even lethal, if inhaled. Also,drilling the frame or under-body of your vehicle could cause dete-rioration of strength of your vehicle and cause corrosion aroundthe drilled hole.
CAUTION
Do not modify the vehicle exhaust system, brake system, or
other systems when installing a hitch or other trailer towingequipment. Do not use axle-mounted hitches as they can cause damage to
the axle housing, wheel bearings, wheels or tires.
Choose a proper hitch for your vehicle and trailer. OUTBACK wagon
The use of a genuine SUBARU trailer hitch is recommended. A genu-
ine SUBARU hitch is available from your SUBARU dealer.
If use of a non-genuine hitch is unavoidable, be sure the hitch is
suited to your vehicle and trailer. Consult with a professional hitch
supplier to assist you in choosing an appropriate hitch for your
vehicle. Be sure to follow all of the hitch manufacturer ’s instructions for
installation and use.
Never use a hitch that mounts only to the rear bumper. The bumper isnot designed to handle that type of load.
For all types of hitches, regularly check that the hitch mounting bolts
and nuts are tight.

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

NOTE
[Automatic transmission vehicle not equipped with VDC (Vehicle Dy-
namics Control) and not equipped with SPORTSHIFT] Before drivingyour vehicle with the temporary spare tire, put a spare fuse insidethe FWD connector located in the engine compartment and confirm
that the Front-wheel drive warning light comes on. The all wheeldrive capability of the vehicle has now been deactivated. After re-
installing the conventional tire, remove the spare fuse from the FWDconnector in order to reactivate all wheel drive.
Flat tires
WARNING
Do not jack up the vehicle on an incline or a loose road sur-
face. The jack can come out of the jacking point or sink into the ground and this can result in a severe accident. Use only the jack provided with your vehicle. The jack sup-
plied with the vehicle is designed only for changing a tire. Neverget under the vehicle while supporting the vehicle with this jack. Always turn the engine off before raising the flat tire off the
ground using the jack. Never swing or push the vehicle sup-ported with the jack. The jack can come out of the jacking pointdue to a jolt and this can result in a severe accident.

Do not use oil or grease on the wheel studs or nuts when the
spare tire is installed. This could cause the nuts to become loose and lead to an accident. Never place a tire or tire changing tools in the passenger
compartment after changing wheels. In a sudden stop or colli-
sions, loose equipment could strike occupants and cause injury.Store the tire and all tools in the proper place.
If you have a flat tire while driving, never brake suddenly; keep driving
straight ahead while gradually reducing speed. Then slowly pull off the
road to a safe place.
1. Park on a hard, level surface, whenever possible, then stop the en- gine.
2. Set the parking brake securely and shift a manual transmission ve-
hicle in reverse or an automatic transmission vehicle in the “P” (Park)
position.
3. Turn on the hazard warning flasher and have everyone get out of thevehicle.
4. Put wheel blocks at the front and rear of the tire diagonally opposite
the flat tire.

12. Put on the spare tire. Replace the wheel nuts. Tighten them by hand.
13. Turn the jack handle counterclockwise to lower the vehicle.
14. Use the wheel nut wrench to securely tighten the wheel nuts to the
specified torque, following the tightening order in the illustration.
OM-H0377
The torque for tightening the nuts is 58 to 72 ft-lb (78 to 98 N-m, 8 to 10
kg-m). This torque is equivalent to applying about 88 to 110 lbs (40 to 50
kg) at the top of the wheel nut wrench. Never use your foot on the wheel
nut wrench or a pipe extension on the wrench because you may exceed
the specified torque. Have the wheel nut torque checked at the nearest
automotive service facility.
15. Store the flat tire in the spare tire compartment.
