that there is a problem or potential prob-
lem somewhere in the emission control
system.
If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
NOTE
This light also comes on when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized SUBARU dealer immediately.
If the light is blinking:
If the light is blinking while driving, an en-
gine misfire condition has been detected
which may damage the emission control
system.

placard attached to the driver ’s side door
pillar. It includes the total weight of the
driver and all passengers and their be-
longings, 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 Ve-
hicle Weight Rating and
Gross Axle Weight Rating)
The certification plate attached to the driv-
er ’s side door jamb 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, fu-
el, driver, all passengers, luggage, any optional equipment and trailer tongue
load. Therefore, the GVW changes de-
pending on the situation. The GVWR
equals Curb Weight (actual weight of your
vehicle
– including standard equipment,
fluids, emergency tools and spare tire as-
sembly) plus the vehicle capacity 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 inside the
vehicle.
Even if the total weight of your luggage is
lower than the vehicle capacity weight, ei-
ther 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 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 in-
crease the GVWR and GAWR limitations.
Roof rail and crossbar (if
equipped)
1) Crossbar kit
The roof rail is not designed to carry cargo
by itself. Cargo can be carried after secur-
ing the roof crossbar kit to the roof rail and
installing the appropriate carrying attach-
ment. When installing the roof crossbar
kit, follow the manufacturer ’s instructions.
When you carry cargo on the roof using
the roof crossbar kit and a carrying attach-
ment, never exceed the maximum load
limit explained in the following. 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

6) Front arrow label
a: 0 inch (0 mm)
Install the rear crossbar in the same man-
ner as the front crossbar.
NOTE
The rear crossbar should be posi-
tioned just in front of the rear seam
(joint) between the rear roof rail sup-
port and the roof rail.
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)
The trailer hitch is designed to tow a Class
1 rated load. A maximum of 2,000 lbs
(906 kg) gross trailer weight and a maxi-
mum of 200 lbs (90 kg) gross tongue
weight are permissible for the trailer hitch.
When you tow a trailer, follow the instruc-
tions in the section “Trailer towing ” in this
chapter.
Connecting a trailer
1. Remove the receiver cover from the
hitch receiver tube. Then insert the ball
mount into the hitch receiver tube.
Do not carry cargo on the roof when
the crossbars are removed. Lug-
gage on the roof will be thrown for-
ward or backward in sudden stops
or rapid accelerations, resulting in a
dangerous road hazard.
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 section
“Trailer
towing ” in this chapter for possi-
ble recommendations and limita-
tions.
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 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.
Be 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 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 dis-
tributing hitch.

8-18 Driving tips
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 securely into the
hitch pin.
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 ac-
count; however, be careful not to let them
drag on the ground.

four-pin wire connector to the towing trail-
er ’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 pro-
tect against possible damage.
Occasionally lubricate terminals of the
four-pin connector using 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 safe-
ty and satisfaction depend upon proper
use of correct equipment and cautious op-
eration of your vehicle. Seek the advice of
your SUBARU dealer to assist you in pur-
chasing a hitch and other necessary tow-
ing equipment appropriate for your vehi-
cle. In addition, be sure to follow the in-
structions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for in-
juries or vehicle damage that result from
trailer towing equipment, or from any er-
rors or omissions in the instructions ac-
companying such equipment or for your
failure to follow the proper instructions.
Warranties and maintenance
SUBARU warranties do not apply to vehi-
cle damage or malfunction caused by trail-
er towing. If you use your vehicle to tow a
trailer, more frequent maintenance will be

required due to the additional load. (Refer
to “Maintenance schedule under severe
driving conditions ” in the “Warranty and
Maintenance Booklet ”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving.
Maximum load limits
