CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.
& Fuel requirements
! 2.5-liter non-turbo models
The 2.5-liter non-turbo engine is designed
to operate using unleaded gasoline with
an octane rating of 87 AKI or higher. ! 2.5-liter turbo models
The 2.5-liter turbo engine is designed to
operate using premium unleaded gasoline
with an octane rating of 91 AKI or higher. If
premium unleaded gasoline is not avail-
able, regular unleaded gasoline with an
octane rating of 87 AKI or higher may be
temporarily used. For optimum engine
performance and driveability, it is required
that you use premium grade unleadedgasoline. NOTE
Be sure to use premium unleaded
gasoline of 91 AKI or higher for a 2.5-
liter turbo engine model. If other gaso-
line (lower than 91 AKI) is used, knock-
ing, reduced output and poor accelera-
tor response will result. !
3.0-liter models
The 3.0-liter engine is designed to operate
using unleaded gasoline with an octane
rating of 91 AKI or higher. Regular
unleaded gasoline with an octane rating
of 87 AKI or higher may be used. However
for optimum engine performance and
driveability, it is recommended that you
use 91 AKI or higher grade unleaded
gasoline. You may experience reduced
output, poor accelerator response, and
reduced fuel economy when using gaso-
line with an octane rating lower than 91
AKI, depending on your driving habits and
conditions. If you experience any of these
conditions while using a lower octane
rated fuel, you may want to return to using
91 AKI octane rated fuel as soon as
possible. Additionally, if your vehicle
knocks heavily or persistently, or if you
are driving with heavy loads such as when
towing a trailer, the use of 91 AKI or higher
grade unleaded gasoline is required. !
Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle
sometimes knocks lightly when you drive
up a hill or when you accelerate. See your
dealer or a qualified service technician if
you use a fuel with the specified octane
rating and your vehicle knocks heavily or
persistently. ! Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will
damage the emission control system and
may impair driveability and fuel economy. ! California fuel
If your vehicle was certified to California
Emission Standards as indicated on the
underhood tune-up label, it is designed to
optimize engine and emission control
system performance with gasoline that
meets the clean burning low-sulfur Cali-
fornia gasoline specifications. If you live in
any other state than California, your Starting and operating

NOTE .Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.. When driving off immediately after
starting the engine, a short-lived opera-
tion noise may be noticed coming from
the engine compartment. This noise is
generated as a result of a check being
performed on the Vehicle Dynamics
Control system and is normal.. Depending on the timing of activa-
tion of the brakes, the brake pedal may
seem to jolt when you drive off after
starting the engine. This is a conse-
quence of the Vehicle Dynamics Con-
trol operational check and is normal.. In the circumstances listed in the
following, the vehicle may be more
unstable than it feels to the driver.
The Vehicle Dynamics Control System
may therefore operate. Such operation
does not indicate a system fault.
.on gravel-covered or rutted roads
. on unfinished roads
. when the vehicle is towing a
trailer .
when the vehicle is fitted with
snow tires or winter tires
. Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normalconditions. . Even if the vehicle is equipped with
a Vehicle Dynamics Control system, it
is important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand).
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the
vehicle in such a condition. . It is always important to reduce
speed when appro aching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control. . All four wheels should be fitted with
tires of the same size, type, and brand;
furthermore, the amount of wear
should be the same for all four tires. If
these precautions are not observed
and non-matching tires are used, it is
quite possible that the Vehicle Dy- namics Control system will be unable
to operate correctly as intended. .
Always turn off the engine before
replacing a tire as failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly.

of the driver and all passengers and their
belongings, any optional equipment such
as a trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer. &GVWR and GAWR (Gross
Vehicle Weight Rating and
Gross Axle Weight Rating)
Certification label
The certification label attached to the driver ’s side door shows GVWR (Gross
Vehicle Weight Rating) 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 optional equipment and trailer tongue
load. Therefore, the GVW changes de-
pending on the situation.
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 inside thevehicle.
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 confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle 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 limita-
tions. Replacement tires with a higher load
range than the originals do not increase
the GVWR and GAWR limitations.
&
Roof rail and crossbar (if equipped)
1) Crossbar kit
CAUTION
. 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 cargo. Otherwise,
damage to the roof or paint or a
dangerous road hazard due to
loss of cargo could result.
. When using the roof crossbar kit,
make sure that the total weight of
the crossbars, carrying attach- Driving tips

NOTE
Before each use of the roof crossbar,
make sure the four T-30 crossbar
clamp screws have been checked,
and retightened if necessary to 35 lbf·in
(4.0 N·m, 0.41 kgf·m), as outlined in
Step #5 above.Trailer hitch (if equipped)
WARNING
. Never exceed the maximum
weight specified for the trailer
hitch. Exceeding the maximum
weight could cause an accident
resulting in serious personal in-
juries. Permissible trailer weight
changes depending on the situa-
tion. Refer to the next section“ Trailer towing ”for possible re-
commendations and limitations.
. Trailer 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 max-
imum gross weight. Towing trai-
lers without safety chains could
create a traffic safety hazard if
the trailer separates from the
hitch due to coupling damage or
hitch ball damage.
. Be sure to check the hitch pin
and safety pin for positive lock-
ing placement before towing a
trailer. If the ball mount comes off
the hitch receiver, the trailer
could get loose and create a traffic safety hazard.
. Use 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
distributing hitch.
The trailer hitch is designed to tow a Class
1 rated load. The maximum gross trailer
weight and maximum gross tongue weight

& 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 receiver tube so that the pin passes
through the ball mount.
3. Insert the safety pin into the hitch pin
securely.
4. Pull the ball mount to make sure it
does not come off the hitch receiver.
1) Hitch ball installation point
2) 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
account; however, be careful not to let
them drag on the ground.

WARNING
Do not connect safety chains to part
of the vehicle other than the safety
chain hooks.
Hitch harness connector
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. NOTE
Always disconnect the trailer wire har-
ness before launching or retrieving a watercraft.
& When you do not tow a trailer
. Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube. . Place the dust cap over the four-pin
connector of the hitch wire harness to
protect against possible damage. . Occasionally lubricate terminals of the
four-pin connector using the terminal grease. Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle
’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the advice of
your SUBARU dealer to assist you in
purchasing a hitch and other necessary
towing equipment appropriate for your
vehicle. In addition, be sure to follow the
instructions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for
injuries or vehicle damage that result from
trailer towing equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure to follow the proper instructions.
& Warranties and maintenance
SUBARU warranties do not apply to
vehicle damage or malfunction caused
by trailer towing. If you use your vehicle to
tow a trailer, more frequent maintenance
will be required due to the additional load. Driving tips
