Clutch Fluid (MT models)
354Visually check the brake fluid level of the
reservoir monthly on the even surface.1) “MAX” level line
2) “MIN” level lineBe sure to check the brake fluid level from
the outside of the reservoir. If the fluid
level is below “MIN”, top up brake fluid to
“MAX”. Use only brake fluid from a sealed
container.
■ Recommended Brake FluidRefer to "Fluids" P383.
11-15. Clutch Fluid (MT models)■ Checking the Fluid Level
Be careful not to spill brake fluid
when adding it. If brake fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If brake fluid gets on the
exhaust pipe, be sure to wipe it
off.

CAUTION
Never use different brands of brake
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even
if they are the same brand.
WARNING
Never let clutch fluid contact your
eyes because clutch fluid can be
harmful to your eyes. If clutch fluid
gets in your eyes, immediately flush
them thoroughly with clean water.
For safety, when performing this
work, wearing eye protection is
advisable.
CAUTION
 Clutch fluid absorbs moisture
from the air. Any absorbed mois-
ture 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. When you add clutch fluid, be
careful not to allow any dirt into
the tank.

Visually check the fluid level of the reser-
voir monthly on the even surface. Be sure
to check the clutch fluid level from the
outside of the reservoir. If the fluid level is
below “MIN”, top up clutch fluid to “MAX”.
Use only clutch fluid from a sealed
container.■ Recommended Clutch FluidRefer to "Fluids" P383.
11-16. Brake BoosterThe brake booster utilizes the vacuum
produced by the vacuum pump to reduce
the force required to depress the brake
pedal.
The vacuum in the brake booster may be
insufficient if the brake pedal is depressed
when the engine is stopped or after the
vehicle has been parked for a long period
of time. It such cases, it is necessary to
depress the brake pedal using greater
force than usual.
 Never splash the clutch fluid over
painted surfaces or rubber parts.
Alcohol containe d 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. Check the fluid level for the clutch
system at the inboard side of the
reservoir. You cannot check the
fluid level at the outboard side of
the reservoir.

according to the maintenance schedule in
the “Warranty and Maintenance Booklet”.
11-19. Replacement of BrakePad and Lining
CAUTION
 If you continue to drive despite
the scraping noise from the
audible brake pad wear indicator,
it will result in the need for costly
brake rotor repair or replacement. It is recommended that you
disconnect the vehicle battery
before replacing the brake pad.
However, it is dangerous to
disconnect the vehicle battery.
We recommend that you have
your SUBARU dealer replace the

■Manual Transmission and Differential Gear Oil*1: The indicated oil quantity is only a guideline. The necessary quantity for replacement may differ slightly depending on the temperature and other
factors. After refilling the gearbox wi th oil, the oil level should be checked.
*2: For more details about maintenance and service, refer to the indicated section.
*3: The vehicle is filled at the factory.
*4: This type of manual transmission oil can be used. However, using this type of oil will increase fuel consumption.
If oil other than “Manual Transmission Gear Oil LV 75W” is used, the following may be experienced:
 The overall performance and function of the transmission may be adversely affected.
 Rattling noises may occur during id ling and fuel consumption may increase.
Never use different brands together.
