ABS (Anti-lock Brake Sys-
tem)
The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.
The ABS will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).

driving–overconfidence because
you are driving a vehicle with the
ABS could easily lead to a serious
accident.
CAUTION
. The ABS does not always de-
crease stopping distance. You
should always maintain a safe following distance from other
vehicles.
. When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
. When tire chains are installed,
stopping distances may be long-
er for a vehicle with the ABS than
one without. Be sure to reduce
your speed and maintain a safe
distance from the vehicle in front.
. When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
& ABS self-check
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is caused by an automatic functional test of
the ABS being carried out and does not
indicate a malfunction.

exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the rear gate closed while
driving to prevent exhaust gas
from entering the vehicle.
NOTE
Due to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
Catalytic converter
Non-turbo models
Turbo models
The catalytic converter is installed in the
exhaust system. It serves as a catalyst to reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust.
To avoid damage to the catalytic conver-
ter:
.
Use only unleaded fuel. Even a small
amount of leaded fuel will damage the
catalytic converter.
. Never start the engine by pushing or
pulling the vehicle.
. Avoid racing the engine.
. Never turn the ignition switch to the
“OFF ”position while the vehicle is moving.
. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
. Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-
tem.
. Do not drive with an extremely low fuel
level.
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.,
grass, paper, rags or leaves),
because the catalytic converter

conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
. Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side.
. Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the
“Warranty and Maintenance Booklet ”.

– Brake fluid
– Rear differential gear oil
– Manual transmission oil (MT mod-
els)
– Continuously variable transmission
fluid (CVT models)

must observe when towing your vehicle.
For detailed information, refer to “Towing ”
F 9-13.On-road and off-road driving
WARNING
. In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. You the driver and
all your passengers should fas-
ten the seatbelts before starting
to drive in order to minimize the
chance of serious injury or death.
. Do not make sharp turns and
quick maneuvers unless abso-
lutely unavoidable. Such actions
are dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-
tions.
. Whenever strong crosswinds are
present, slow down sufficiently
to maintain control of your vehi-
cle. Remember that your vehicle,
with its higher profile and center of gravity, is more likely to be
affected by crosswinds than or-
dinary passenger cars.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive model could easily
lead to a serious accident.
Your vehicle is classified as a utility
vehicle. Utility vehicles feature a higher
ground clearance which enables them to
be used for wide applications including off-
road driving. But please keep in mind that
your vehicle is neither a conventional off-
road vehicle nor an all-terrain vehicle. A
higher center of gravity in relation to the
tread width as compared with ordinary
passenger cars makes vehicles of this
type more likely to roll over. In reality, utility
vehicles have a significantly higher roll-
over rate than other types of vehicles. The
high ground clearance of this vehicle is a
real advantage, giving you a better view of
the road and allowing you to anticipate
problems earlier. However, remember that
your utility vehicle is not designed for high-
speed cornering comparable to ordinary
passenger cars and that your vehicle
could roll over if you make a sharp turn
at high speed.
If you take your SUBARU off-road, certain
8-6

common sense precautions such as those
in the following list should be taken.
.Make certain that you and all of your
passengers are wearing seatbelts.
. Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
. Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
. Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
. Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
. Avoid sharp turning maneuvers, espe-
cially at higher speeds.
. Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim.
. If driving through water, such as when
crossing shallow streams, first check the depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and cross the stream without stopping.
The water should be shallow enough that
it does not reach the vehicle’
s under-
carriage. Water entering the engine air
intake or the exhaust pipe or water
splashing onto electrical parts may da-
mage your vehicle and may cause it to
stall. Never attempt to drive through
rushing water; regardless of its depth, it
can wash away the ground from under
your tires, resulting in possible loss of
traction and even vehicle rollover.
. Always check your brakes for effec-
tiveness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
. Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after engine
stops. This could create a fire hazard.
. After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
.
Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. During
sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’ s
center of gravity and make it more prone
to tip over.
. If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/
select lever back and forth between “1”/
“D ”and “R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
. When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st. For CVT models with
manual mode, refer to “Selection of
manual mode ”F 7-27.
. Never equip your vehicle with tires
larger than those specified in this manual.
. Wash the vehicle’ s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they

need to be washed thoroughly.
.Frequent driving of an AWD model
under hard-driving conditions such as
rough roads or off roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the
maintenance schedule described in the
“Warranty and Maintenance Booklet ”.
– Engine oil

– Rear differential gear oil
– Manual transmission oil (MT mod-
els)

Remember that damage done to your
SUBARU while operating it off-road and
not using common sense precautions
such as those listed above is not eligible
for warranty coverage.Winter driving
& Operation during cold
weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle. SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid Con-
centration Freezing Temperature
30% 10.4 8F( −12 8C)
50% −48F( −20 8C)
100% −
49 8F( −45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
nozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
8-8

side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
!
Parking in cold weather
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, you should observe the following
tips.
1. Place the shift lever in “1”or “R”for MT
models, or the select lever in “P”for CVT
models.
2. Use tire stops under the tires to
prevent the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked
after use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-
ness.WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity.
! Opening rear gate (models with
power rear gate)
CAUTION
Before operating the power rear
gate, check that there is no frost or
snow between the power rear gate
and the vehicle body. If you notice

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. Do not use towing equipment
other than genuine SUBARU towing
equipment. In addition, be sure to follow
the instructions on correct installation and
use provided by SUBARU.
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.
Regularly check that the hitch mounting
bolts and nuts are tightened securely.
& 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 “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
WARNING
Never exceed the maximum load
limits explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle damage.
CAUTION
. Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg) total weight.
. Before towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are accepta-
ble.
