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.

as they may burn easily if they come near hot engine or exhaust system parts.Be sure to stop the engine if you take a nap
in the vehicle. If engine exhaust gas enters the
passenger compartment, occupants in the ve-hicle could die from carbon monoxide (CO) contained in the exhaust gas.
CAUTION
If your vehicle has a front underspoiler and rear underspoiler (both optional), pay atten- tion to blocks and other obstructions on the ground when parking. The underspoilerscould be damaged by contact with them. Cruise control (if equipped)
Cruise control enables you to maintain a constant
vehicle speed without holding your foot on the ac-
celerator pedal and it is operative when the vehicle
speed is 25 mph (40 km/h) or more. Make sure the
main switch is turned
“OFF” when the cruise control
is not in use to avoid unintentionally by setting the
cruise control.WARNING
Do not use the cruise control under any of the following conditions. This may cause loss of
vehicle control: driving up or down a steep grade
driving on slippery or winding roads
driving in heavy traffic

To temporarily cancel the cruise con- trol
There are four ways to cancel the cruise control tem- porarily: Depress the brake pedal.
Pull the control lever in the “CANCEL” direction. (if
so equipped) Depress the clutch pedal (manual transmission
vehicles only). Shift the selector lever into the “N” position (auto-
matic transmission vehicles only).
To resume the cruise control after it has been tem- porarily canceled and with vehicle speed of about
20 mph (32 km/h) or more, push the control lever
upward in the “ACCEL, RESUME ” direction to return
to the original cruising speed automatically.
To turn off the cruise control
There are two ways to turn off the cruise control: Push the main switch again.
Turn the ignition switch to the “ACC” or “LOCK”
position (but only when the vehicle is completely stopped).
To change the cruising speed
To increase the speed (by control lever)
Push the control lever upward in the “ACCEL, RE-
SUME” direction and hold it until the vehicle reaches
the desired speed. Then, release the control lever.
The vehicle speed at that moment will be memo-
rized and treated as the new set speed.
When the difference between the actual vehicle
speed and the set speed is less than 4 mph (6.8
km/h), the set speed can be increased 1 mph (1.6
km/h) each time by pressing the control lever up-
ward in the “ACCEL, RESUME ” direction quickly
within 0.5 second.
To increase the speed (by accelerator pedal)
1. Depress the accelerator pedal to accelerate the
vehicle to the desired speed.
2. Push the control lever downward in the “SET,
COAST” direction once. Now the desired speed is
set and the vehicle will keep running at that speed
without depressing the accelerator pedal.
NOTE
If the difference between the actual vehicle speed when the control lever is pushed down-ward and the speed last time you set is less than

Off road driving
WARNING
Always maintain a safe driving speed ac-
cording to the road and weather conditions in order to avoid having an accident on a sharpturn, during sudden braking or under othersimilar conditions. Always use the utmost care in driving –
overconfidence because you are driving an allwheel drive vehicle could easily lead to a seri-ous accident.
All AWD models except OUTBACK SPORT
Your AWD vehicle is neither a conventional off-road
vehicle nor an all terrain vehicle. It is a passenger
car designed primarily for on-road use. The AWD
feature gives it some limited off-road capabilities in
situation in which driving surfaces a relatively level,
obstruction-free and otherwise similar to on-road driving conditions. Operating it under other than those conditions could subject the vehicle to exces-
sive stress which might result in damage not eligible for repair under warranty. If you do take your
SUBARU off road, you should review the common
sense precautions in the next section (applicable to
the OUTBACK SPORT) for general guidance. Butplease keep in mind that your vehicle
’s off-road ca-
pabilities are more limited than those of the OUT-
BACK SPORT.
Never attempt to drive through pools and puddles,
or roads flooded with water. 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. OUTBACK SPORT
Because of the AWD feature and higher ground
clearance, your Subaru can be driven on ordinary
roads or off-road. But please keep in mind that an
AWD SUBARU is a passenger car and is neither a
conventional off-road vehicle nor an all-terrain ve-
hicle. If you do take your Subaru off-road, certain
common sense precautions such as the following should be taken: Make certain that you and all of your passengers
are wearing seat belts. Carry some emergency equipment, such as a
towing rope or chain, a shovel, wheel blocks, first

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.

WARNING
Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the
exhaust pipe and from around your vehicle ifyou 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 anti-
freeze additive in the fuel tank is recommended dur-
ing 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 ex-
tended 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 ve-
hicle and the vehicle ahead of you to avoid the needfor 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 behavior cancause the wheels to lock, possibly leading to loss of
vehicle control.
An anti-lock brake system (ABS) e
nhances your
vehicle’ s braking performance on snowy and icy
roads. Refer to the “ABS (Anti-Lock Brake System) ”
section in chapter 7 for information on braking on
slippery surfaces. NOTE The optional 17-inch tires for the WRX are sum- mer tires. Compared with winter and all-season tires, summer tires give significantly less grip on
snowy and icy road surfaces. Avoid driving onsnowy and icy road surface with summer tires.

for positive locking placement before towing a
trailer. If the ball mount comes off the hitch re-
ceiver, the trailer could get loose and create atraffic safety hazard.Use only the ball mount supplied with this
hitch. Use the hitch only as a weight carrying
hitch. Do not use with any type of weight dis- tributing hitch.
Connecting a trailer
1. Remove the receiver cover from the hitch receiv-
er tube. Then insert the ball mount into the hitch re- ceiver tube.2. Insert the hitch pin into the hole on the hitch re-
ceiver tube so that the pin passes through the ballmount.
3. Insert the safety pin securely into the hitch pin.
4. Pull the ball mount to make sure it does not come
off the hitch receiver.

Driving tips

If your vehicle has an automatic transmission,
avoid using the accelerator pedal to stay stationary on an uphill slope instead of using the parking brakeor foot brake. That may cause the transmission fluid
to overheat. Also, if your vehicle is equipped with an
automatic transmission, avoid driving with the gear selector lever in “D” when towing a heavy trailer to
prevent fluid overheating. A lower gear should be used.
Parking on a grade
Always block the wheels under both vehicle and
trailer when parking. Apply the parking brake firmly.
You should not park on a hill or slope. But if parking on a hill or slope cannot be avoided, you shouldtake the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under boththe vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb theload.
4. Apply the regular brakes and then apply the
parking brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmis- sion) or “P” (automatic transmission) and shut off the
engine.

Flat tires
If you have a flat tire while driving, never brake sud- denly; keep driving straight ahead while gradually
reducing speed. Then slowly pull off the road to asafe place. Changing a flat tire
WARNING
Do not jack up the vehicle on an incline or a
loose road surface. The jack can come out of
the jacking point or sink into the ground and this can result in a severe accident. Use only the jack provided with your ve-
hicle. The jack supplied with the vehicle is de-signed only for changing a tire. Never get un-der the vehicle while supporting the vehicle with this jack. Always turn the engine off before raising the
flat tire off the ground using the jack. Neverswing or push the vehicle supported with the
jack. The jack can come out of the jackingpoint due to a jolt and this can result in a
severe accident. 1. Park on a hard, level surface, whenever possible,
then stop the engine.
2. Set the parking brake securely and shift a manual
transmission vehicle in reverse or an automatictransmission vehicle in the
“P” (Park) position.
3. Turn on the hazard warning flasher and have ev-
eryone get out of the vehicle.
4. Put wheel blocks at the front and rear of the tire
diagonally opposite the flat tire.
