Power steering
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine 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 before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is nor-
mal. It does not indicate power steering
system trouble.
Braking
Braking tips
When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a re-
sult, brake stopping distance will be long-
er. To dry the brakes, drive the vehicle at
a safe speed while lightly depressing the
brake pedal to heat up the brakes.
Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking.
Braking when a tire is punctured
Do not depress the brake pedal suddenly when a tire is punctured. This could cause
a loss of control of the vehicle. Keep driv-
ing straight ahead while gradually reduc-
ing speed. Then slowly pull off the road to
a safe place.
Brake system
Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diago-
nally across the vehicle. If one circuit of
the brake system should fail, the other half
of the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to push the pedal much harder
than normal and the braking distance will
increase.
Do not hold the steering wheel at the
fully locked position left or right for
more than five seconds. This may
damage the power steering pump.
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.

Driving tips 8-27
heating of your vehicle ’s brakes. Do not
make sudden downshifts.
When driving uphill in hot weather, the
air conditioner 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 relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing ” section in chapter 9, and “Warning
and indicator lights ” section in chapter 3.
If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat.
If your vehicle has an automatic trans-
mission, place the selector lever as fol-
lows:
Uphill slopes: “D ” position
Downhill slopes: A low-speed gear posi-
tion to use engine braking
Parking on a grade
Always block the wheels under both vehi-
cle 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 should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P ” (automatic transmis-
sion) and shut off the engine.

Engine overheating
If the engine overheats, safely pull off the
road and stop the vehicle in a safe place.
If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays at the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the
“LOW ”
mark, add coolant up to the “FULL ” mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following pro-
cedures for safety.
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
Never tow AWD vehicles (both AT
and MT) with the front wheels raised
off the ground while the rear wheels
are on the ground, or with the rear
wheels raised off the ground while
the front wheels are on the ground.
This will cause the vehicle to spin
away due to the operation or deteri-
oration of the center differential.
