Rear viscous limited slip differential (LSD) (WRX)
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left rear wheels that may be caused by
certain driving conditions, thereby improving driving
stability on snow-covered, muddy or other slippery
roads.
CAUTION
Never start the engine while a tire on one
side is jacked up, as the vehicle may move. If one rear tire is spinning in mud, avoid
continued spinning at high speed as thiscould adversely affect the LSD. If a different size rear tire is temporarily
used (as in an emergency), it will adversely af-fect the LSD. Always replace it with a regularsize tire as soon as possible. Power steering The power steering system operates only when the
engine is running.If you lose power steering assist because the en-gine stops or the system fails to function, you can
steer but it will take much more effort. NOTE Right after the engine has been started and be- fore it has warmed up, you may hear a noisecoming from areas adjacent to the power steer-
ing pump which is located at the right-front area of the engine compartment. This noise is normal. It does not indicate power steering systemtrouble.
CAUTION
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steer- ing pump.

much harder than normal and the braking distance
will increase. Disc brake pad wear warning indica- tors
The disc brake pad wear warning indicators on the
disc brakes give a warning noise when the brake
pads are worn.
If a squeaking or scraping noise is heard from the disc brakes while braking, immediately have your
vehicle checked by your SUBARU dealer. ABS (Anti-lock Brake System)
The ABS system 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 system 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 system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h).
WARNING
Always use the utmost care in driving
– over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to aserious accident.

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 temperature in a closed vehiclecould quickly become high enough to cause
severe or possibly fatal injuries to people. Do not park the vehicle over flammable ma-
terials such as dry grass, waste paper or rags,

aid kit and portable phone or citizens band radio. Drive carefully. Do not take unnecessary 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 ve-
hicle 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, especially at
higher speeds. Do not grip the inside or spokes of the steering
wheel. A bad bump could jerk the wheel and injureyour hands. Instead drive with your fingers andthumbs 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 completely through the stream. The water
should be shallow enough that it does not reach the
vehicle’ s undercarriage. Water entering the engine
air intake or the exhaust pipe or water splashing
onto electrical parts may damage 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 effectiveness im-
mediately 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 outthe brake discs and brake pads. Do not drive or park over or near flammable mate-
rials 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 the engine stops.
This could create a fire hazard. After driving through tall grass, mud, rock, sand,
rivers, etc., check that there is no grass, bush, pa-
per, 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 ma-
terials 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 seat-
backs. During sudden stops or jolts, unsecured car-
go could be thrown around in the vehicle and cause
injury. Do not pile heavy loads on the roof. Thoseloads raise the vehicle ’s center of gravity and make

cold weather. Heavy summer oil will cause harder
starting.
Keep the door locks from freezing by squirting themwith deicer or glycerin.
Forcing a frozen door open may damage or sepa-
rate the rubber weather strips around the door. If the
door is frozen, use hot water to melt the ice, and af-
terwards thoroughly wipe the water away. Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or oth-
er substitutes because they may damage the paint of the vehicle.
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the ped-
als slippery and dangerous.
While warming up the vehicle before driving, check that the accelerator pedal, brake pedal, and all oth-
er controls operate smoothly. Clear away ice and snow that has accumulated un-
der 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 peri-
odically.
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, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmis-
sion vehicles.
2. Use tire stops under the tires to prevent the ve-
hicle from moving.
When the vehicle is parked in snow or when it
snows, raise the wiper blades off the glass to pre-vent 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 onthe brake system, which could cause poor braking
action. Check for snow or ice buildup on the sus-
pension, disc brakes and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being care-ful not to damage the disc brakes and brake hoses
and ABS harness.

Trailer lights
Connection of trailer lights to your vehicle ’s electrical
system requires modifications to the vehicle ’s light-
ing circuit to increase its capacity and accommo-
date wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU
dealer. Check for proper operation of the turn sig-nals, the brake lights and parking lights each timeyou hitch up.
CAUTION
Direct splicing or other improper connection
of trailer lights may damage your vehicle ’s
electrical system and cause a malfunction ofyour vehicle ’s lighting system.
Tires
Make sure that all the tires on your vehicle are prop-
erly inflated to the pressure specified on the tire
placard located on the left center pillar of your ve-hicle.
Trailer tire condition, size, load rating and proper
inflation pressure should be in accordance with the trailer manufacturer
’s specifications.
In the event your vehicle gets a flat tire when towing
a trailer, ask a commercial road service to repair the
flat tire.
If you carry a regular size spare tire in your vehicle
or trailer as a precaution against getting a flat tire,
be sure that the spare tire is firmly secured.
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not
designed to sustain the towing load. Use ofthe temporary spare tire when towing canresult in failure of the spare tire and/or less
stability of the vehicle.
Trailer towing tips
CAUTION
Never exceed 45 mph (72 km/h) when tow-
ing a trailer in hilly country on hot days. When towing a trailer, steering, stability,
stopping distance and braking performancewill be different from normal operation. For

safety’s sake, you should employ extra cau-
tion when towing a trailer and you should
never speed. You should also keep the follow-ing tips in mind:
Before starting out on a trip
Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are
apparent, do not tow the trailer. 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 accept-able. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected
properly. Confirm that
–the trailer tongue is connected properly to the
hitch ball.– the trailer lights connector is connected prop-
erly and trailer ’s brake lights illuminate when the
vehicle’ s brake pedal is pressed, and that the trail-
er’ s turn signal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected properly. –
all cargo in the trailer is secured safety in posi-
tion.– the side mirrors provide a good rearward field of
view without a significant blind spot.
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.
Driving with a trailer
You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden brak-
ing because it may result in skidding or jackknifing
and loss of control. Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate
engine revolution. Avoid uneven steering, sharp turns and rapid lane
changes. Slow down before turning. Make a longer than
normal turning radius because the trailer wheels will
be closer than the vehicle wheels to the inside of the
turn. In a tight turn, the trailer could hit your vehicle. Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswindscan be due to weather conditions or the passing of

large trucks or buses. If swaying occurs, firmly grip the steering wheel and slow down immediately but
gradually.When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn 2) Right turn
Backing up with a trailer is difficult and takes
practice. When backing up with a trailer, never
accelerate or steer rapidly. When turning back, gripthe 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.
If the ABS warning light illuminates while the
vehicle is in motion, stop towing the trailer and have
repairs performed immediately by the nearest
SUBARU dealer.
Driving on grades
Before going down a steep hill, slow down and
shift into lower gear (if necessary, use 1st gear) in
order to utilize the engine braking effect and prevent
overheating of your vehicle ’s brakes. Do not make
sudden downshifts. When driving uphill in hot weather, the air condi-
tioner may turn off automatically to protect the
engine from overheating. 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 rel-
atively prone to overheating under these conditions.
If the water temperature gauge pointer approaches
the OVERHEAT zone or the AT OIL TEMP warning
light illuminates, immediately switch off the air condi-
tioner and stop the vehicle at the nearest safe place.Refer to the “Engine overheat ” section in chapter 9,
and “Warning and indicator lights ” section in chap-
ter 3.
