Driving tips
Trailer towingYour 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 maintenanceSUBARU 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
T Total trailer weightTotal trailer weightThe total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight shown in the following
table.
Never exceed the maximum load
limits explained in the following. Ex-
ceeding the maximum load limits
could cause personal injury and/or
vehicle damage.
yAdequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)

Gross Vehicle Weight Rating
(GVWR)Gross Vehicle WeightThe Gross Vehicle Weight (GVW) must
never exceed the Gross Vehicle Weight
Rating (GVWR).
Gross Vehicle Weight (GVW) is the com-
bined total of the weight of the vehicle,
driver, passengers, luggage, trailer hitch,
trailer tongue load and any other optional
equipment installed on your vehicle.
Therefore, the GVW changes depending
on the situation. Determine the GVW each
time before going on a trip by putting your
vehicle and trailer on a vehicle scale.

F: Front of vehicleThe tongue load can be adjusted by prop-
er distribution of the load in the trailer.
Never load the trailer with more weight in
the back than in the front; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as even-
ly 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.
„Trailer hitchesChoose a proper hitch for your vehicle and
trailer.
The use of a genuine SUBARU trailer
hitch is recommended. A genuine
SUBARU hitch is available from your
SUBARU dealer.
If use of a non-genuine hitch is unavoid-
able, be sure the hitch is suited to your ve-
hicle and trailer. Consult with a profes-
sional hitch supplier to assist you in
choosing an appropriate hitch for your ve-
hicle. Be sure to follow all of the hitch man-
ufacturer’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.

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, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing.
Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your ve-
hicle and cause corrosion around
the drilled hole.
y
Do not modify the vehicle exhaust
system, brake system, or other
systems when installing a hitch or
other trailer towing equipment.
y Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.

Driving tips
„Connecting a trailerT Trailer brakes
If your trailer’s total weight (trailer weight
plus its cargo weight) exceeds 1,000 lbs
(453 kg), the trailer is required to be
equipped with its own brake system. Elec-
tric brakes or surge brakes are recom-
mended, and must be installed properly.
Check that your trailer’s brakes conform
with Federal, state/province and/or other
applicable regulations. Your SUBARU’s
brake system is not designed to be tapped
into the trailer’s hydraulic brake system.
Please ask your SUBARU dealer and pro-
fessional trailer supplier for more informa-
tion about the trailer’s brake system.
T Trailer safety chains
In case the trailer hitch connector or hitch
ball should break or become disconnect-
ed, the trailer could get loose and create a
traffic safety hazard.
For safety, always connect the towing ve-
hicle and trailer with trailer safety chains.
Pass the chains crossing each other un-
der the trailer tongue to prevent the trailer
from dropping onto the ground in case the
trailer tongue 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.
For more information about the safety
chain connection, refer to the instructions
for your hitch and trailer.
T Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors pro-
vide a good rearward field of view without
significant blind spots. If significant blind
spots occur with the vehicle’s standard
side mirrors, use towing mirrors that con-
form with Federal, state/province and/or
other applicable regulations.
T Trailer lights
Connection of trailer lights to your vehi-
cle’s electrical system requires modifica-
tions to the vehicle’s lighting circuit to in-
crease its capacity and accommodate wir-
ing changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals, the brake
y Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.yDo not directly connect your trail-
er’s hydraulic brake system to the
hydraulic brake system in your
vehicle. Direct connection would
cause the vehicle’s brake perfor-
mance to deteriorate and could
lead to an accident.
Always use safety chains between
your vehicle and the trailer. Towing
a trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch ball
damage.

Make sure that all the tires on your vehicle
are properly inflated to the pressure spec-
ified on the tire placard located on the driv-
er’s side center pillar.
Trailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer manufacturer’s
specifications.„ Trailer towing tips
T Before starting out on a trip
y Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer.
y Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable.
y Check that the tire pressures are cor-
rect.
y Check that the vehicle and trailer are
connected properly. Confirm that – the trailer tongue is connected prop-
erly to the hitch ball.
– the trailer lights connector is connect-
ed properly and trailer’s brake lights illu-
minate when the vehicle’s brake pedal
is pressed, and that the trailer’s turn sig- nal lights flash when the vehicle’s turn
signal lever is operated.
– the safety chains are connected prop-
erly.
– all cargo in the trailer is secured safe-
ty in position.
– the side mirrors provide a good rear-
ward 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 re-
sult in skidding or jackknifing and loss of
control.
y Avoid abrupt starts and sudden acceler-
ations. If your vehicle has a manual trans-
mission, always start out in first gear and
release the clutch at moderate engine rev-
olution.
y Avoid uneven steering, sharp turns and
rapid lane changes.
y Slow down before turning. Make a long-
er than normal turning radius because the
trailer wheels will be closer than the vehi-
cle wheels to the inside of the turn. In a
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’s electrical
system and cause a malfunction of
your vehicle’s lighting system.
y
Never exceed 45 mph (72 km/h)
when towing a trailer in hilly coun-
try on hot days.yWhen towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For
safety’s sake, you should employ
extra caution when towing a trail-
er and you should never speed.
You should also keep the follow-
ing tips in mind:

Driving tips
tight turn, the trailer could hit your vehicle.
yCrosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing 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 im-
mediately but gradually.
y When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by at-
taching the trailer to your vehicle.1) Left turn
2) Right turny Backing up with a trailer is difficult and
takes practice. 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 performed im-
mediately by the nearest SUBARU dealer.
T Driving on grades
y Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts.
y When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
y When driving uphill in hot weather, pay
attention to the water temperature 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 condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3. y
If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat.
y If your vehicle has an automatic trans-
mission, place the selector lever as fol-
lows:
Uphill slopes: “D” position
Downhill slopes: A low-speed gear posi-
tion to use engine braking
T Parking on a grade
Always block the wheels under both vehi-
cle 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 take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-1 2

When using the temporary spare tire, note
the following.
y Do not exceed 50 mph (80 km/h).
y Do not put a tire chain on the temporary
spare tire. Because of the smaller tire
size, a tire chain will not fit properly.
y Do not use two or more temporary
spare tires at the same time.
y Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced.

Vehicle Dynamics Control system) Be-
fore driving your vehicle with the tem-
porary spare tire, put a spare fuse in-
side the FWD connector in the main
fuse box located in the engine com-
partment and confirm that the Front-
wheel drive warning light “AWD” in the
combination meter comes on. The all
wheel drive capability of the vehicle
has now deactivated. After re-installing
the conventional tire, remove the spare
fuse from the FWD connector in order
to reactivate all wheel drive.

„Using a flat-bed truckThis is the best way to transport your vehi-
cle. Use the following procedures to en-
sure safe transportation.
1. Shift the selector lever into the “P” po- sition for automatic transmission vehicles
or “1st” for manual transmission vehicles.
2. Pull up the parking brake lever firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
„
Towing with all wheels on the
ground1. Check the transmission and differential
oil levels and add oil to bring it to the upper
level if necessary.
2. Release the parking brake and put the
transmission in neutral.
3. The ignition switch should be in the
“ACC” position while the vehicle is being towed.
4. Take up slack in the towline slowly to
prevent damage to the vehicle.
y
Use only the specified towing
hooks and tie-down hooks. Never
use suspension parts or other
parts of the body for towing or tie-
down purposes.
y Never use the tie-down hook on
the underside of the vehicle clos-
est to the muffler for towing pur-
poses.

yNever turn the ignition switch to
the “LOCK” position while the ve-
hicle is being towed because the
steering wheel and the direction
of the wheels will be locked.yRemember that the brake booster
and power steering do not func-
tion when the engine is not run-
ning. Because the engine is
turned off, it will take greater ef-
fort to operate the brake pedal and
steering wheel.
y If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
y Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the en-
gine running.

Appearance care
Appearance care
Exterior care„Washing
NOTEWhen having your vehicle washed in
an automatic car wash, make sure be-
forehand that the car wash is of suit-
able type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the ve-
hicle at least once a month to avoid con-
tamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree sap
and bird droppings should be washed off
by using a light detergent, as required. If
you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth.
T Washing the underbody
Chemicals, salts and gravel used for deic-
ing road surfaces are extremely corrosive,
accelerating the corrosion of underbody components, such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders, and suspension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or muddy or sandy
roads, wash the mud and sand off the un-
derbody.
Carefully flush the suspension and axle
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
NOTEBe careful not to damage brake hoses,
sensor harnesses, and other parts
when washing suspension compo-
nents.
T
Using a warm water washer
y Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
y Do not wash the same area continuous-
ly.
y If a stain will not come out easily, wash
by hand. Some warm water washers are
y
When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes, drive
the vehicle at a safe speed while
lightly pressing the brake pedal to
heat up the brakes.
y Do not wash the engine compart-
ment and area adjacent to it. If wa-
ter enters the engine air intake,
electrical parts or the power steer-
ing fluid reservoir, it will cause en-
gine trouble or faulty power steer-
ing respectively.
y Since your vehicle is equipped
with a rear wiper, automatic car-
wash brushes could become tan-
gled around it, damaging the wip-
er arm and other components.
Ask the automatic car-wash oper-
ator not to let the brushes touch
the wiper arm or to fix the wiper
arm on the rear window glass with
adhesive tape before operating
the machine.
