low pressure threshold, the low tire
pressure warning light should turn
off a few minutes later.
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 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 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 possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. If the light
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.CAUTION
. Do not place metal film or any
metal parts in the cargo area/
trunk. This may cause poor re-
ception of the signals from the
tire pressure sensors, and the
tire pressure monitoring system
will not function properly.

7-34Starting and operating/Parking your vehicle
CAUTION
Never drive while the parking brake
is set because this will cause un-
necessary wear on the brake lin-
ings. Before starting to drive, always
make sure that the parking brake
has been fully released.
& Parking tips
When parking your vehicle, always per-
form the following items. . Apply the parking brake firmly.
. Put the shift lever in “1 ” (1st) for an
upgrade or “R ” (Reverse) for a down-
grade.
Never rely on the transmission alone to
hold the vehicle.
When parking on a hill, always turn the
steering wheel. When the vehicle is
headed up the hill, the front wheels should
be turned away from the curb.
When facing downhill, the front wheels
should be turned into the curb.
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks

8-2Driving tips/New vehicle break–in driving –the first 1,000 miles (1,600 km)
New vehicle break-in driving – the first 1,000 miles (1,600
km)
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km): . Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency. . Do not drive at one constant engine or
vehicle speed for a long time, either fast or
slow. . Avoid starting suddenly and rapid
acceleration, except in an emergency.. Avoid hard braking, except in an
emergency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones. Fuel economy hints
The following suggestions will help to save fuel. .
Select the proper gear position for the
speed and road conditions.. Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long aspossible. . Do not pump the accelerator and avoid
racing the engine.. Avoid unnecessary engine idling.
. Keep the engine properly tuned.
. Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on thedriver ’s side. Low pressure will increase
tire wear and fuel consumption. . Use the air conditioner only when
necessary.. Keep the front and rear wheels in
proper alignment.. Avoid carrying unnecessary luggage or
cargo. Engine exhaust gas (carbon
monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
. If at any time you suspect that

Periodic inspections
To keep your vehicle in the best condition
at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the“War-
ranty and Maintenance Booklet ”per-
formed at the specified time or mileageintervals. Driving in foreign countries
When planning to use your vehicle in
another country: .
Confirm the availability of the correct
fuel. Refer to “Fuel requirements ”F 7-3.
. Comply with all regulations and re-
quirements of each country. Driving tips for AWD models
WARNING
. 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.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
. When you replacing or installing
tire(s), all four tires must be the
same for following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For the items (a) to (d), you must
obey the specification that is

printed on the tire placard. The
tire placard is located on the
bottom of driver’s door pillar.
If all of four tires are not the same
for items (a) to (h), there is a
possibility that serious mechan-
ical damage could occur to the
drive train of your car, and affect
the following. — Ride
— Handling
— Braking
— Speedometer/Odometer
calibration— Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
CAUTION
If you use a temporary spare tire to
replace 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.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
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 duringdeceleration.
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
following tips in mind. . An AWD model is better able to climb
steeper roads under snowy or slippery 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 model
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 “Mainte-
nance schedule ”F 11-3.
– Engine oil
– Brake fluid
– Rear differential gear oil
– Manual transmission oil
. There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to “Towing ”
F 9-12.
Driving tips/Driving tips for AWD models8-5

!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 followingtips.
1. Place the shift lever in “1 ” or “R ”.
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 enginerunning.
! 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. &
Driving on snowy and icy roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’s braking perfor-
manceonsnowyandicyroads.For
information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-26 and “Vehicle Dynamics
Control system ”F 7-28.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of

obey the specification that is
printed on the tire placard. The
tire placard is located on the
bottom of driver’s door pillar.
If all of four winter tires are not
the same for items (a) to (h), there
is a possibility that serious me-
chanical damage could occur to
the drive train of your car, and
affect the following. — Ride
— Handling
— Braking
— Speedometer/Odometer
calibration— Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
. Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.
Your vehicle is equipped with “summer
tires ”as original equipment, which are
inadequate for driving on slippery roads
such as on snow-covered or icy roads. Compared with winter and all-season
tires, summer tires give significantly less
grip on snowy and icy road surfaces.
Therefore, use of winter tires is strongly
recommended when driving with such
road conditions.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter
tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on yourvehicle.
& Tire chains
CAUTION
Tire chains cannot be used on your
Impreza, WRX and STI because of
the lack of clearance between the
tires and vehicle body. &
Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever back and forth between “1 ” 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.

The hazard warning flasher should be
used in day or night to warn other drivers
when you have to park your vehicle under
emergency conditions.
Avoid stopping on the road. It is best to
safely pull off the road if a problem occurs.
The hazard warning flasher can be acti-
vated regardless of the ignition switchposition.
Turn on the hazard warning by pushing
the hazard warning flasher switch. Turn it
off by pushing the switch again.NOTE
When the hazard warning flasher is on,
the turn signals do not work.
Temporary spare tire
WARNING
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 tire pressure monitoring system
(TPMS) is unable to monitor all four
road wheels. Contact your SUBARU
dealer as soon as possible for tire
and sensor replacement and/or sys-
tem resetting.
CAUTION
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechan-
ical damage to the drive train of yourvehicle.
The temporary spare tire is smaller and
lighter than a conventional tire and is
designed for emergency use only. Re-
move the temporary spare tire and re-
install the conventional tire as soon as

possible because the spare tire is de-
signed only for temporary use.
Check the inflation pressure of the tem-
porary spare tire periodically to keep the
tire ready for use. The correct pressure is
60 psi (420 kPa, 4.2 kg/cm
2).
When using the temporary spare tire, note
the following. . Do not exceed 50 mph (80 km/h).
. Do not put a tire chain on the temporary
spare tire. Because of the smaller tire size,
a tire chain will not fit properly. . Do not use two or more temporary
spare tires at the same time.. 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
. When the wear indicator appears on
the tread, replace the tire. . 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. Maintenance tools
Your vehicle is equipped with the following
maintenance tools. .
