WARNING
 Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you, thor-
oughly flush the exposed area
with water immedi ately. Get med-
ical help if the fluid has entered
your eyes.If battery fluid is accidentally
swallowed, imme diately drink a
large amount of milk or water,
and obtain immediate medical
help.Keep everyone including chil-
dren away from the battery.
 The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
 Whenever working on or around a
battery, always wear suitable eye
protectors, and remove metal
objects such as rings, bands or
other metal jewelry. Be sure the jumper cables and
clamps on them do not have
loose or missing insulation. Do not jump start unless cables in
suitable condition are available. A running engine can be
dangerous. Keep your fingers,
hands, clothing, hair and tools
away from the cooling fan, belts
and any other moving engine
parts. Removing rings, watches
and ties is advisable. Jump starting is dangerous if it is
done incorrectly. If you are
unsure about the proper proce-
dure for jump starting, consult a
competent mechanic.

Towing
324holes, return the plugs to their original
places.■Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Sh ift the shift lever into
the 1st position for MT models.
2. Apply the parking brake 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 Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.
900488
CAUTION
Transport by flat -bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
and steering wheel.

Parking Brake Stroke
357
Maintenance and Service11
The disc brakes have audible wear indica-
tors on the brake pads. If the brake pads
wear close to their service limit, the wear
indicator makes a very audible scraping
noise when the brake pedal is applied.
If you hear this scraping noise each time
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible.■ Breaking-in of New Brake
Pad s and LiningsWhen replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, the new parts must be
broken in as follows.
▼ Brake pad and lining
While maintaining a speed of 30 to 40 mph
(5 0 to 65 km/h), step on the brake pedal
lightly. Repeat this five or more times.
▼ Parking brake lining1. Drive the vehicle at a speed of approx-
imately 22 mph (35 km/h).
2. With the parking brake release button
pushed in, pull the parking brake lever
SLOWLY and GENTLY (pulling with a
force of approximately 33.7 lbf [150 N,
15.3 kgf]). 3. Drive the vehicle for approximately

220 yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking
brake to cool down. Repeat this proce-
dure.
5. Check the parking brake lever travel. If
the parking brake lever travel is out of the
specified range, adjust it by turning the
adjusting nut located on the parking brake
lever.
11-20. Parking Brake StrokeCheck the parking brak e stroke according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
Parking brake stroke:
7 – 8 notches / 45 lbf (200 N, 20.4 kgf)
WARNING
A safe location and situation should
be selected for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be cer-
tain to pull the lever up slowly and
gently.

Tires and Wheels
35811-21. Tires and Wheels■Types of TiresYou should be familiar with type of tires
present on your vehicle.
▼ Summer tires
The factory-installed tires on your new
vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.
▼ All season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads. All season tires are identified by “ALL

SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
▼ Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼ Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■ Tire Pressure Monitoring
System (TPMS) (If Equipped)The tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low. The
tire pressure monitoring system will acti-
vate only when the vehicle is driven. Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F

(5.6°C) between the temperature in the
garage and the temperature outside. By
way of example, the following table shows
the required tire pressures that corre-
spond to various outside temperatures
when the temperature in the garage is
60°F (15.6°C).
Example:
Tire size: 215/40R18 85Y
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm
2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C)
Example:
Tire size: 215/45R17 87W
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C) If the low tire pressure warning light illumi-
nates when you drive the vehicle in cold

outside air after adjusting the tire pres-
sures in a warm garage, re-adjust the tire
pressures using the method described
above. Then, increase the vehicle speed
to at least 25mph (40km/h) and check to
see that the low tire pressure warning light
goes off a few minutes later. If the low tire
pressure warning light does not go off, the
tire pressure monito ring system may not
be functioning normally. In this event, go
to a SUBARU dealer to have the system
inspected as soon as possible.
While the vehicle is driven, friction
between tires and the road surface
causes the tires to warm up. After illumi-
nation of the low tire pressure warning
light, any increase in the tire pressures
caused by an increase in the outside air
temperature or by an increase in the
temperature in the tires can cause the low
tire pressure warning light to go off. System resetting is
necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-
ment.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
in the instrument panel will illuminate
steadily after blinking for approximately
one minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement,
therefore, you s hould have the work
performed by a SUBARU dealer.

■Tire InspectionCheck on a daily basis that the tires
are free from serious damage, nails,
and stones. At the same time, check
the tires for abnormal wear.
Contact your SUBARU dealer
immediately if you find any problem.NOTE When the wheels and tires
strike curbs or are subjected to
harsh treatment as when the
vehicle is driven on a rough surface, they can suffer damage

that cannot be seen with the
naked eye. This type of damage
does not become evident until
time has passed. Try not to drive
over curbs, potholes or on other
rough surfaces. If doing so is
unavoidable, keep the vehicle’s
speed down to a walking pace or
less, and approach the curbs as
squarely as possible. Also, make
sure the tires are not pressed
against the curb when you park
the vehicle.
 If you feel unusual vibration
while driving or fi nd it difficult to
steer the vehicle in a straight line,
one of the tires and/or wheels
may be damaged. Drive slowly to
the nearest authorized SUBARU
dealer and have the vehicle
inspected.
 Tires should be replaced if:
– You have tire damage such
as cuts, splits, cracks deep
enough to expose the fabric or
bulges indicating internal
damage
WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as so on as possi-
ble.If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise an accident involving
serious vehicle damage and serious
personal injury could occur.1) Keep driving straight ahead while
gradually reducing speed.2) Slowly pull off the road to a safe
place.If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose ai r rapidly. If you
have a flat tire, re fer to "Flat Tires"
 P303.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possi-
ble for tire and sensor replacement
and/or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.

■Wheel BalanceEach wheel was correctly balanced
when your vehicle was new, but the
wheels will become unbalanced as
the tires become worn during use.
Wheel imbalance causes the
steering wheel to vibrate slightly at
certain vehicle speeds and detracts
from the vehicle’s straight-line
stability. It can also cause steering
and suspension system problems
and abnormal tire wear. If you
suspect that the wheels are not
correctly balanced, have them
checked and adjusted by your
SUBARU dealer. Also have them
adjusted after tire repairs and after
tire rotation.
NOTEThe suspension system is
designed to hold each wheel at a
certain alignment (relative to the
other wheels and to the road) for
optimum straight-line stability
and cornering performance.■ Wear Indicators1) New tread
2) Worn tread3)
Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible
when the depth of the tread grooves
decreases to 0.063 in (1.6 mm). A tire must be replaced when the

tread wear indicator appears as a
solid band across the tread.
NOTEFor safety, inspect the tire tread
regularly and replace the tires
before their tread wear indicators
become visible.
CAUTION
Loss of correct wheel align-
ment causes the tires to wear
on one side and reduces the
vehicle’s running stability.
Contact your SUBARU dealer
if you notice abnormal tire
wear.
12 3
B00327
WARNING
When a tire’s tread wear indi-
cator becomes visible, the tire
is worn beyond the accept-
able limit and must be
replaced immediately. With a
tire in this condition, driving at
high speeds in wet weather
can cause the vehicle to
hydroplane. The resulting loss
of vehicle control can lead to
an accident.

WARNING
 Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and
lighters. Never expose a battery
to an open flame or electric
sparks. Batteries give off a gas
which is highly flammable and
explosive. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery. Do not let battery fluid contact
eyes, skin, fabrics, or paint
because battery fluid is a corro-
sive acid. If battery fluid gets on
your skin or in your eyes, immedi-
ately flush the area with water
thoroughly. Seek medical help
immediately if acid has entered
the eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention
immediately.

11-27. Installation of Acces-soriesAlways consult your SUBARU dealer
before installing fog lights or any other
electrical equipment in your vehicle. Such
accessories may cause the electronic
system to malfunction if they are incor-
rectly installed or if they are not suited for
the vehicle. We recommend that you
install only genuine SUBARU accessories
on your vehicle.
11-28. Replacing Bulbs
■ HeadlightsThe LED headlight warning light illumi-
nates if the LED headlights malfunction.
Have your vehicle inspected at a
SUBARU dealer as soon as possible.■ Backup LightNOTEIt may be difficult to replace the
bulbs. We recommend that you have
the bulbs replaced by your SUBARU
dealer if necessary.
 If a genuine SUBARU accessory has
been installed to the rear bumper,
check the manual included with the
accessory.
WARNING
Bulbs may become very hot while
illuminated. Before replacing bulbs,
turn off the lights and wait until the
bulbs cool down, Otherwise, there
is the risk of sustaining a burn
injury.
CAUTION
 Before replacing a backup light,
stop the engine and allow the
exhaust pipes and surrounding
parts to cool suffi ciently. As the
bulbs are near the exhaust pipes,
there is a risk of being burned. Replace any bulb only with a new
bulb of the specified wattage.
Using a bulb of different wattage
could result in a fire. For the spec-
ified wattage of each bulb, refer to
"Bulb Chart" P387. For replace-
ment, contact your SUBARU
