– CONTINUED –seconds to check that the tire pressure
monitoring system (TPMS) is functioning
properly. If there is no problem and all tires
are properly inflated, the light will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure rec-
ommended by the vehicle manufacturer
on the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a
different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the prop-
er inflation pressure for those tires.) As an
added safety feature, your vehicle has
been equipped with a tire pressure moni-
toring system (TPMS) that illuminates a
low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driv-
ing on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to main-
tain correct tire pre ssure, even if under-in- flation has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
The TPMS gives warning both when a tire
is significantly under-inflated and when
there is a problem in the TPMS. The low
tire pressure warning light operates differ-
ently according to these conditions as fol-
lows:
When a tire is significantly under-inflat-
ed: Steady illumination
When there is a problem in the TPMS:
Flashing
Should the warning light flash, have the
system inspected by your nearest
SUBARU dealer as soon as possible.
If this light does not come on briefly
after the ignition switch is turned
ON or the light is flashing, you
should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble. If this light comes on while driving,
never brake suddenly and keep driv-
ing straight ahead while gradually
reducing speed. Then slowly pull off
the road to a safe place. Otherwise
an accident involving serious vehi-
cle damage and serious personal in-
jury could occur.
If this light still comes on while driv-
ing after adjusting the tire pressure,
a tire may have significant damage
and a fast leak that causes the tire to
lose air rapidly. If you have a flat
tire, replace it with a spare tire as
soon as possible.
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 flash. This in-
dicates the TPMS is unable to moni-
tor all four road wheels. Contact
your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, promptly contact a
SUBARU dealer to have the system
inspected.

7-24 Starting and operating
To override the shift lock:
1. Set the parking brake and stop the en-
gine.
2. Take out the screwdriver from the tool
bucket.
3. Remove the cover by prying on the
edge with a flat-head screwdriver. 4. Insert the screwdriver into the hole.
5. Push down on the screwdriver and
move the selector leve r from the “P” to the
“N” position.
6. Remove the screwdriver from the hole.
Depress the brake pedal and start the en-
gine.
Take your vehicle to the nearest SUBARU
dealer immediately to have the system re-
paired. Rear viscous limited slip dif-
ferential (LSD) (if equipped)
The LSD provides optimum distribution of
power according to the difference in revo-
lutions between the right and left rear
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads.700346 700347
y Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
y If one rear tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely af-
fect the LSD.
y If a different size rear tire is tem-
porarily used (as in an emergen-
cy), it will adversely affect the
LSD. Always replace it with a reg-
ular size tire as soon as possible.

Starting and operating

– CONTINUED –Vehicle Dynamics Control
system (if equipped)y Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
y If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair. Always use the utmost care in driv-
ing – overconfidence because you
are driving with a Vehicle Dynamics
Control system equipped vehicle
could easily lead to a serious acci-
dent.
y Even if your vehicle is equipped
with Vehicle Dynamics Control,
winter tires or snow chains
should be used when driving on
snow-covered or icy roads; in ad-
dition, vehicle speed should be re-
duced considerably. Simply hav-
ing a Vehicle Dynamics Control
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation. y Activation of the Vehicle Dynam-
ics Control system is an indica-
tion that the ro ad being travelled
on has a slippery surface; since
having Vehicle Dynamics Control
is no guarantee that full vehicle
control will be maintained at all
times and under all conditions, its
activation should be seen as a
sign that the speed of the vehicle
should be reduced considerably.
y Whenever suspension compo-
nents, steering components, or an
axle are removed from a vehicle
equipped with Vehicle Dynamics
Control, have an authorized
SUBARU dealer perform an in-
spection of that system.
y The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Control
system is operating properly:
– All four wheels should be fitted
with tires of the same size, type,
and brand. Furthermore, the
amount of wear should be the
same for all four tires.

7-30 Starting and operating
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system ad-
justs the engine’s output and the wheels’
respective braking forces to help maintain
traction and directional control.
y Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dynam-
ics Control operation indicator light.
y Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTE
y Slight twitching of the brake pedal may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or st eering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.
y When driving off immediately after
starting the engine, a short-lived oper-
ation noise may be noticed coming
from the engine compartment. This
noise is generated as a result of a
check being performed on the Vehicle
Dynamics Control system and is nor-
mal.
y Depending on the timing of activa-
tion of the brakes, certain situations
may occur just after driving off where
the brake pedal seems to exhibit a jolt-
ing motion. This too is a consequence
of the Vehicle Dynamics Control opera-
tional check and is normal.
y In the circumstances listed in the fol-
lowing, the vehicle may be more unsta-
ble than it feels to the driver. The Vehi-
cle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.
y on gravel-covered or rutted roads
y on unfinished roads
y when the vehicle is towing a trailer
y when the vehicle is fitted with snow tires or winter tires
y Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly dif-
ferent compared to that for normal con-
ditions.
y Even if the vehicle is equipped with a
Vehicle Dynamics Control system, it is
important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand).
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the ve-
hicle in such a condition.
y It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with Ve-
hicle Dynamics Control.
y All four wheels shou ld be fitted with
tires of the same size, type, and brand;
furthermore, the amount of wear
should be the same for all four tires. If
these precautions are not observed
and non-matching tires are used, it is
quite possible that the Vehicle Dynam-
ics Control system will be unable to op-– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to the
driver’s side door pillar.

Driving tips for AWD vehicles
All-Wheel Drive distributes the engine
power to all four wheels. AWD vehicles provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By
shifting power between the front and rear
wheels, SUBARU AWD can also provide
added traction during acceleration, and
added engine braking force during decel-
eration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the fol-
lowing tips in mind:
y An AWD vehicle is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or sud-
den braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an am-
ple distance from other vehicles.
y When replacing a ti re, make sure you
use only the same si ze, circumference,
construction, brand, and load range as the
original tires listed on the tire placard. Us-
ing other sizes, circumferences or con-
struction may result in severe mechanical
damage to the drive train of your vehicle
and may affect ride, handling, braking, speedometer/odometer calibration, and
clearance between the body and tires. It
also may be dangerous and lead to loss of
vehicle control.
y If you use a temporary spare tire to re-
place a flat tire, be sure to use the original
temporary spare tire stored in the vehicle.
Using other sizes may result in severe
mechanical damage to the drive train of
your vehicle.
y Always check the cold tire pressure be-
fore starting to drive. The recommended
tire pressure is provided on the tire plac-
ard, which is located under the door latch
on the driver’s side.
y Tire chains should always be placed on
the front wheels only.
y There are some precautions that you
must observe when towing your vehicle.
For detail information, see “Towing” sec-
tion in chapter 9.y 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 braking
or under other similar conditions.
y Always use the utmost care in
driving – overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.

8-12 Driving tips
require the use of tire chains, in which
case put the chains on the front wheels
only. Use only SAE class S type chains
that are of the correct size for your tires so
as not to damage the vehicle body or sus-
pension.
When driving with tire chains, drive at
speeds below 19 mph (30 km/h). When a
temporary spare tire is on a front wheel,
replace the temporary spare tire with the
rear tire on the same side of the vehicle,
and then fit chains on the front tires.
Always use the utmost care when driving
with tire chains – overconfidence because
you are driving with tire chains could eas-
ily lead to a serious accident.
„ Rocking the vehicleIf you must rock the ve hicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the selector
lever back and forth between “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 slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
Refer to the “Automatic transmission – 4- speed” and “Automatic transmission – 5-
speed” section in chapter 7 for information
on holding the transmission in 2nd posi-
tion.
Loading your vehicle Never allow passengers to ride on a
folded rear seatback, in the trunk or
in the cargo area. Doing so may re-
sult in serious injury.
y Never stack luggage or other car-
go higher than the top of the seat-
back because it could tumble for-
ward and injure passengers in the
event of a sudden stop or acci-
dent. Keep luggage or cargo low,
as close to the floor as possible. 100094

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 weight
Total trailer weight
The total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight indicated 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.
y Adequate 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 and trailer are acceptable.

In case of emergency
9-3
The temporary spare tire is smaller and
lighter than a conventional tire and is de-
signed for emergency use only. Remove
the temporary spare tire and re-install the
conventional tire as soon as possible be-
cause the spare tire is designed only for
temporary use.
Check the inflation pressure of the tempo-
rary spare tire periodically to keep the tire
ready for use. The correct pressure is 60
psi (420 kPa, 4.2 kgf/cm 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. 1) Tread wear indicator bar
2) Indicator location mark
y When the wear indicator appears on the
tread, replace the tire.
y The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel. NOTE If your vehicle is an AWD type with an
automatic transmission but is neither a
Turbo model nor a 3.0-liter model, de-
activate its All-Wheel-Drive capability
as follows: Before driving your vehicle
with the temporary spare tire, put a
spare fuse inside the FWD connector
located in the engi ne compartment and
confirm that the “ ” warning
light comes on. The All-Wheel-Drive
capability of the vehicle has now been
deactivated. After re -installing the con-
ventional tire, remove the spare fuse
from the FWD connector in order to re-
activate All-Wheel Drive.Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechani-
cal damage to the drive train of your
vehicle. 1

Appearance care
10-3NOTE Be 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
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as mouldings, or cause
water to leak in to the vehicle.
„ Waxing and polishingAlways wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and ap-
ply them according to the manufacturer’s
instructions. Wax or polish when the paint-
ed surface is cool.
Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the su rface. It is recom- mended that a coat of wax be applied at
least once a month, or whenever the sur-
face no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the sur-
face with a fine-grained compound. Never
polish just the affected area, but include
the surrounding area as well. Always pol-
ish in only one direction. A No. 2000 grain
compound is recommended. Never use a
coarse-grained compound. Coarser
grained compounds have a smaller grain-
size number and could damage the paint.
After polishing with a compound, coat with
wax to restore the original luster. Frequent
polishing with a compound or an incorrect
polishing technique will result in removing
the paint layer and exposing the under-
coat. When in doubt, it is always best to
contact your SUBARU dealer or an auto
paint specialist.
NOTE Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.
„ Cleaning aluminum wheels y Promptly wipe the aluminum wheels
clean of any kind of gr ime or agent. If dirt is left on too long, it may be difficult to
clean off.
y Do not use soap containing grit to clean
the wheels. Be sure to use a neutral clean-
ing agent, and later rinse thoroughly with
water. Do not clean the wheels with a stiff
brush or expose them to a high-speed
washing device.
y Clean the vehicle (including the alumi-
num wheels) with water as soon as possi-
ble when it has been splashed with sea
water, exposed to sea breezes, or driven
on roads treated with salt or other agents.

11 - 3 8 Maintenance and service
Tire wear varies from wheel to wheel. To
maximize the life of each tire and ensure
that the tires wear uniformly, it is best to
rotate the tires every 7,500 miles (12,500
km). Rotating the tires involves switching
the front and rear ti res on the right-hand
side of the vehicle and similarly switching
the front and rear tires on the left-hand
side of the vehicle. (Each tire must be kept
on its original side of the vehicle.)
Replace any damaged or unevenly worn
tire at the time of rotation. After tire rota-
tion, adjust the tire pressures and make
sure the wheel nuts are correctly tight-
ened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.
„ Tire replacementThe wheels and tires are important and in-
tegral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires fit-
ted as standard equipment are optimally
matched to the characteristics of the vehi-
cle and were selected to give the best pos-
sible combination of running performance,
ride comfort, and service life. It is essential
for every tire to have a size and construc-
tion matching those shown on the tire placard and to have a speed symbol and
load index matching those shown on the
tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU rec-
ommends replacing all four tires at the
same time.
„ Wheel replacement When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers. y All four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of dif-
ferent types, sizes or degrees of
wear can result in damage to the
vehicle’s power train. Use of dif-
ferent types or si zes of tires can
also dangerously reduce control-
lability and braking performance
and can lead to an accident.
y Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires. Do-
ing so can dangerously reduce
controllability, resulting in an ac-
cident.
