Maintenance and service/Brake booster
Alcohol contained in the clutch
fluid may damage them.
. Be careful not to spill clutch fluid
when adding it. If clutch fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If clutch fluid gets on the
exhaust pipe, be sure to wipe it
off.
. The fluid level for the clutch
system must be checked at the
inboard side of the reservoir. It
cannot be checked at the out-
board side of the reservoir.
1) “MAX ”level line
2) “MIN ”level line
A) The clutch fluid level must be checked in this area.
Check the fluid level monthly.
Check the fluid level on the outside of the
reservoir. Because this reservoir is used
for both the brake and clutch systems and
has chambers for each system, be sure to
check the fluid level for the clutch system
at the inboard side of the reservoir
(shaded area in the illustration). If the fluid
level is below “MIN ”, add the recom-
mended clutch fluid to “MAX”.
Use only clutch fluid from a sealed
container.
& Recommended clutch fluid
Refer to “Fluids”F 12-8.
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand.
Brake booster
If the brake booster does not operate as
described in the following procedure, have
it checked by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several 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
approximately 1 minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pedal
stroke decreases with each depression.

Brake pedal
Check the brake pedal free play and
reserve distance according to the main-
tenance schedule in the“Warranty and
Maintenance Booklet ”.
&Checking the brake pedal
free play
1) 0.02 –0.11 in (0.5 –2.7 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly pull the
brake pedal up with one finger to check
the free play with a force of less than 2 lbf
(10 N, 1 kgf).
If the free play is not within proper
specification, contact your SUBARU deal-
er.
& Checking the brake pedal
reserve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbf (294 N, 30 kgf) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer.
Clutch pedal (MT models)
Check the clutch pedal free play according
to the maintenance schedule in the
“Warranty and Maintenance Booklet ”.
&Checking the clutch function
Check the clutch engagement and disen-
gagement.
1. With the engine idling, check that there
are no abnormal 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 couple without
any sign of slippage.

Specifications/Specifications
&Engine oil
For the checking, adding and replacing procedure or other details, refer to “Engine oil ”F 11-11.
NOTEThe procedure for changing the engine oil and oil filter should be performed by a properly-trained expert. It is recommended
that you have this service performed by your SUBARU dealer.
! Approved engine oil
Always use the SUBARU approved engine oil. For further details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
! Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.
NOTE
. Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
. In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommended viscosities and applicable temperatures.
. When adding oil, different brands may be used together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.
