door jamb shows GVWR (Gross Vehicle Weight Rat-
ing) and GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must never exceed
the GVWR. GVW is the combined total of weight of the
vehicle, fuel, driver, all passengers, luggage, any op-
tional equipment and trailer tongue load. Therefore,
the GVW changes depending on the situation. The
GVWR equals Curb Weight (actual weight of your ve-
hicle – including standard equipment, fluids, emergen-
cy tools and spare tire assembly) plus the vehicle ca-
pacity weight.
In addition, the total weight applied to each axle
(GAW) must never exceed the GAWR. The front and
rear GAWs can be adjusted by relocating luggage in-
side the vehicle.
Even if the total weight of your luggage is lower than
the vehicle capacity weight, either front or rear GAW
may exceed the GAWR, depending on the distribution
of the luggage.
When possible, the load should be evenly distributed
throughout the vehicle.
If you carry heavy loads in the vehicle, you should con-
firm that GVW and front and rear GAWs are within the
GVWR and GAWR by putting your vehicle on a vehi-
cle scale, found at a commercial weighing station.
Do not use replacement tires with a lower load range than the originals because they may lower the GVWR
and GAWR limitations. Replacement tires with a high-
er load range than the originals do not increase the
GVWR and GAWR limitations. „
Roof rail and crossbar (if equipped)
The roof rail is not designed to carry cargo by itself.
Cargo can be carried after securing the roof crossbar
kit to the roof rail and installing the appropriate carry-
ing attachment. When installing the roof crossbar kit,
follow the manufacturer’s instructions.
When you carry cargo on the roof using the roof cross-
bar kit and a carrying attachment, never exceed the
maximum load limit explained below. You should also
be careful that your vehicle does not exceed the Gross
Vehicle Weight Rating (GVWR) and front and rear
Gross Axle Weight Rating (GAWR). See the “Loading
your vehicle” section in this chapter for information on
loading cargo into or onto your vehicle. The maximum
load limit of the cargo, crossbars and carrying attach-
ment must not exceed 150 lbs (68 kg). Place the
heaviest load at the bottom, nearest the roof, and
evenly distribute the cargo. Always properly secure allcargo.

Driving tips
y
For cargo carrying purposes, the roof rail
must be used together with a roof crossbar kit
and the appropriate carrying attachment. The
roof rail must never be used alone to carry car-
go. Otherwise, damage to the roof or paint or a
dangerous road hazard due to loss of cargo
could result.y When using the roof crossbar kit, make sure
that the total weight of the crossbars, carrying
attachment and cargo does not exceed the
maximum load limit. Overloading may cause
damage to the vehicle and create a safety haz-
ard.
T Installing carrying attachments on the cross-
bars
When installing any carrying attachment such as a
bike carrier, ski carrier, kayak carrier, cargo basket,
etc. on the crossbars, follow the manufacturer’s in-
structions and make sure that the attachment is se-
curely fixed to the crossbars. Use only attachments
designed specifically for the crossbars. A set of cross-
bars is designed to carry loads (cargo and attachment)
of not more than 150 lbs (68 kg). Before operating the vehicle, make sure that the cargo is properly secured
on the attachment.
NOTE
Remember that the vehicle’s center of gravity is al-
tered with the weight of the load on the roof, thus
affecting the driving characteristics.
Drive carefully. Avoid rapid starts, hard cornering
and abrupt stops. Crosswind effects will be in-
creased. T
Removal and installation of the crossbars
The crossbars can be removed when you do not use
the roof to carry cargo.

NOTE
It may be necessary to start the inner clamp and
end support at the center of the roof rail for easier
installation, then move the crossbar forward. Use
care not to cross-thread the screw in the insert if it
has been removed.
5. Adjust the alignment of the crossbar on the roof
rails, and if available, use a T-30 torx® bit and torque
wrench and tighten the T-30 torx® head screws to 30
to 35 lbf·in (3.4 to 4.0 N·m, 0.35 to 0.41 kgf·m) of
torque (or tighten securely with the torx® wrench pro-
vided). Rear crossbar:
A) T-30 torx® head screw
B) Front arrow label
C) 6 in (150 mm)
Install the rear crossbar in the same manner as the front crossbar.
NOTE
The rear crossbar should be positioned 6 inches
(150 mm) forward of the rear radius in the roof rail.
Do not carry cargo on the roof when the cross-

traffic safety hazard.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.
„ 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 hitch receiv- er tube so that the pin passes through the ball mount.
3. Insert the safety pin securely into the hitch pin.
4. Pull the ball mount to make sure it does not come
off the hitch receiver.

Driving tips
A) Hitch ball installation point
B) Hooks for safety chains
5. Use only a hitch ball that is appropriate for the ball
mount and your trailer. The hitch ball must be securely
installed on the ball mount.
6. Connect your trailer to the hitch ball.
7. Connect the trailer and the hitch with safety chains
that will hold the trailer’s maximum gross weight. The
chains should cross under the trailer tongue to prevent
the tongue from dropping onto the ground in case it
should disconnect from the hitch ball. Allow sufficient
slack in the chains taking tight-turn situations into ac-
count; however, be careful not to let them drag on the ground.
Do not connect safety chains to part of the ve-hicle other than the safety chain hooks.

8. Connect the hitch wire harness’s black four-pin
wire connector to the towing trailer’s wire harness
9. Confirm proper function of the hitch wire harness
by individually activating the brake, right turn signal,
left turn signal, stop, and parking lights on the trailer.

Driving tips
F: Front of vehicle
The tongue load can be adjusted by proper distribution
of the load in the trailer. Never load the trailer with
more weight in the back than in the front; approximate-
ly 60 percent of the trailer load should be in the front
and approximately 40 percent in the rear. Also, distrib-
ute the load as evenly as possible on both the left and
right sides.
Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving.
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 towing vehicle.
This may cause the rear wheels to skid, espe-
cially during braking or when vehicle speed is
reduced during cornering, resulting in over-
steer, spin out and/or jackknifing.
„ Trailer hitches
Choose a proper hitch for your vehicle and trailer.
The use of a genuine SUBARU trailer hitch is recom-
mended. A genuine SUBARU hitch is available fromyour 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 is not designed to handle that type of
load.
For all types of hitches, regularly check that the hitch
mounting bolts and nuts are tight.

Driving tips
– 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.
y 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 traffic, practice turning, stopping
and backing up. T Driving with a trailer
y You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden braking
because it may result in skidding or jackknifing and
loss of control.y 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 en-
gine revolution. y Avoid uneven steering, sharp turns and rapid lane
changes. y Slow down before turning. Make a longer than nor-
mal 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 your vehicle. y 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 gradu- ally.y
When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
A) Left turn
B) Right turn
y Backing up with a trailer is difficult and takes prac-
tice. When backing 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. y If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs

Flat tires
If you have a flat tire while driving, never brake sud-
denly; keep driving straight ahead while gradually re-
ducing speed. Then slowly pull off the road to a safe
place. „Changing a flat tire
yDo not jack up the vehicle on an incline or a
loose road surface. The jack can come out of
the jacking point or sink into the ground and
this can result in a severe accident.y Use only the jack provided with your vehicle.
The jack supplied with the vehicle is designed
only for changing a tire. Never get under the ve-
hicle while supporting the vehicle with this jack. y Always turn the engine off before raising the
flat tire off the ground using the jack. Never
swing or push the vehicle supported with the
jack. The jack can come out of the jacking point
due to a jolt and this can result in a severe acci-
dent. 1. Park on a hard, level surface, whenever possible,
then stop the engine.
2. Set the parking brake securely and shift a manual
transmission vehicle in reverse or an automatic trans-
mission vehicle in the “P” (Park) position.
3. Turn on the hazard warning flasher and have ev-
eryone get out of the vehicle.
4. Put wheel blocks at the front and rear of the tire di-
agonally opposite the flat tire.

11.Put on the spare tire. Replace the wheel nuts.
Tighten them by hand.
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.
12.Turn the jack handle counterclockwise to lower the
vehicle. 13.Use the wheel nut wrench to securely tighten the
wheel nuts to the specified torque, following the tight-
ening order in the illustration.
The torque for tightening the nuts is 58 to 72 lbf·ft (80
to 100 N·m, 8 to 10 kgf·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 automo-
tive service facility.
14.Store the flat tire in the spare tire compartment.
Put the spacer and tighten the attaching bolt firmly.
Also store the jack and wheel nut wrench in their stor-
