Driving tips

Do not grip the inside or spokes of the steering
wheel. A bad bump could jerk the wheel and injure
your hands. Instead drive with your fingers and
thumbs 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 com-
pletely through the stream. The water should be shal-
low 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; re-
gardless of its depth, it can wash away the ground
from under your tires, resulting in possible loss of trac-
tion and even vehicle rollover. Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads. Do not drive or park over or near flammable materi-
als 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, riv-
ers, etc., check that there is no grass, bush, paper,
rags, stones, sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from the under-
body. If the vehicle is use d with these materials
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 seatbacks.
During sudden stops or jolts, unsecured cargo could
be thrown around in the vehicle and cause injury. Do
not pile heavy loads on the roof. Those loads raise the
vehicle’s center of gravity and make it more prone to
tip over. If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and move
the selector lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For the best pos-
sible 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 (both for MT and AT). Never equip your vehicle with tires larger than those
specified in this manual. Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-

result in an oil leak.
11.Close the access cover by turning it clockwise and
reinstall the six clips in their original positions.
12.Pour engine oil through the filler neck.
Oil quantity (guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After pouring oil
into the engine, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal.
14.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
again and if necessary, add more engine oil.
Recommended grade and viscosity
Oil grade:
API classification SL or SJ with the words “ENER-
GY CONSERVING” (if you cannot obtain the oil
with the SL or SJ grade, you may use SH or SG
grade oil.) or the new API certification mark (Star-
burst mark) displayed on the container.
API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities

Maintenance and service
Any absorbed moisture can cause improper
clutch operation.
If the vehicle requires frequent refilling, there
may be a leak. If you suspect a problem, have
the vehicle checked at your SUBARU dealer. Never use different brands of clutch fluid to-
gether. When clutch fluid is added, be careful not to
allow any dirt into the tank.
Recommended clutch fluid
FMVSS No. 116, fresh DOT 3 or 4 brake fluid
Brake booster
If the brake booster does not operate as described be-
low, have it checked by your SUBARU dealer.
1. With the engine off, depress the brake pedal sever-
al times, applying the same pedal force each time. The
distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine.
The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The
pedal height should not change.
4. Start the engine again and run for about one minute
then turn it off. Depress the brake pedal several times
to check the brake booster. Brake booster operates
properly if the pedal stroke decreases with each de-
pression.

Brake pedal
Check the brake pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Checking the brake pedal free play
1) 0.04–0.12in(1.0–3.0mm)
Stop the engine and firmly depress the brake pedal
several times. Lightly press the brake pedal down with
one finger to check the free play with a force of less
than2lb(10N,1kg).
If the free play is not within proper specification, con- tact your SUBARU dealer.
Checking the brake pedal reserve dis- tance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approximately 66 lb
(294 N, 30 kg) and measure the distance between the
upper surface of the pedal pad and the floor.
When the measurement is smaller than the specifica-
tion, or when the pedal does not operate smoothly,
contact with your SUBARU dealer.

Maintenance and service
Clutch pedal (MT vehicles)
Check the clutch pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”.
Checking the clutch function
Check the clutch engagement and disengagement.
1. With the engine idling, check that there are no ab-
normal noises when the clutch pedal is depressed,
and that shifting into 1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal slowly to
check that the engine and transmission smoothly cou-
ple without any sign of slippage.
Checking the clutch pedal free play
1) 0.16 – 0.51 in (4.0 –13.0 mm)
Lightly press the clutch pedal down with your finger
until you feel resistance, and check the free play.
If the free play is not within proper specification, con-
tact your SUBARU dealer.
