condition has been detected which may damage the
emission control system.
To prevent serious damage to the emission control
system, you should do the following:
yReduce vehicle speed.
y Avoid hard acceleration.
y Avoid steep uphill grades.
y Reduce the amount of cargo, if possible.
y Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking
and come on steadily after several driving trips. You
should have your vehicle checked by an authorized
SUBARU dealer immediately. „ Charge warning light
If this light comes on when the engine is running, it
may indicate that the charging system is not working
properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the alternator belt. If the belt is
loose, broken or if the belt is in good condition but the
light remains on, contact your nearest SUBARU deal-
er immediately. „
Oil pressure warning light
If this light comes on when the engine is running, it
may indicate that the engine oil pressure is low and the
lubricating system is not working properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the engine oil level. If the oil lev-
el is low, add oil immediately. If the engine oil is at the
proper level but the light remains on, contact your
nearest SUBARU dealer immediately.
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.

„Vehicle capacity weight The load capacity of your vehicle is determined by
weight, not by available cargo space. The maximum
load you can carry in your vehicle is shown on the ve-
hicle placard attached to the driver’s side door pillar. It
includes the total weight of 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. „

Driving tips
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)
1) Crossbar kit
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.

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 maximum of 200 lbs (90 kg) gross
tongue weight are permissible for the trailer hitch.
When you tow a trailer, follow the instructions in the
section “Trailer towing” in this chapter.
y Never exceed the maximum weight specified
for the trailer hitch. Exceeding the maximum
weight could cause an accident resulting in se-
rious personal injuries. Permissible trailer
weight changes depending on the situation. Re-
fer to the section “Trailer towing” in this chap-
ter for possible recommendations and limita- tions.y 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 cre-
ate a traffic safety hazard if the trailer separates
from the hitch due to coupling damage or hitch
ball damage. y
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 re-
ceiver, the trailer could get loose and create a
traffic safety hazard.y 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.
„ Connecting a trailer
1. Remove the receiver cover from the hitch receiver
tube. Then insert the ball mount into the hitch receiver
tube.

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.
Do not connect safety chains to part of the ve-
hicle other than the safety chain hooks.

Hitch harness connector – Wagon
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 harness before
launching or retrieving a watercraft. „ When you do not tow a trailer
y Remove the ball mount from the hitch receiver tube and insert the receiver cover onto the hitch receiver tube.y
Place the dust cap over the four-pin connector of the
hitch wire harness to protect against possible damage.y Occasionally lubricate terminals of the four-pin con-
nector using terminal grease.

Trailer towing
Your vehicle is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a trail-
er puts additional loads on your vehicle’s engine, driv-
etrain, brakes, tires and suspension and has an ad-
verse effect on fuel economy.
If you do decide to tow a trailer, your safety and satis-
faction depend upon proper use of correct equipment
and cautious operation of your vehicle. Seek the ad-
vice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac-
turers.
SUBARU assumes no responsibility for injuries or ve-
hicle damage that result from trailer towing equipment,
or from any errors or omissions in the instructions ac-
companying such equipment or for your failure to fol-
low 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. (Refer to “Main- tenance 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 (engine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles (1,600 km) of
driving. „
Maximum load limits
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum load
limits could cause personal injury and/or vehi-
cle damage.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle
