Maintenance and Service11
1) “MAX” level line2) “MIN” level line
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.

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.

Replacement of Wiper Blades
367
Maintenance and Service11
– CONTINUED –
If you fill the windshield washer tank with
a fluid with a different concentration from
the one used previously, purge the old
fluid from the piping between the wind-
shield washer tank and washer nozzles by
operating the washer for a certain period
of time. Otherwise, if the concentration of
the fluid remaining in the piping is too low
for the outside temperature, it may freeze
and block the nozzles.
11-24. Replacement of Wiper BladesGrease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield washer or if
the wiper operation is jerky, clean the
outer surface of the windshield using a
sponge or soft cloth with a neutral deter-
gent or mild-abrasive cleaner. Do not,
however, use detergent to clean the blade
rubbers. Use only a sponge or soft cloth
(and no neutral deterge nt or mild abrasive
cleaner) when you clean the blade
rubbers. If you wipe the rubber of the
blade strongly, the black coating compo-
nent will peel off, which will cause the
wiper to judder. Also, after wiping it off,
check that the rubber has not come loose.
After cleaning the window glass and wiper
blade rubbers, be sure to rinse them with
clean water. Rinse the window until the
water does not form beads on the glass.
This indicates that the glass is clean.
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
CAUTION
 Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank. Be careful foreign matter does
not contaminate the washer fluid
when filling the tank. Contamina-
tion could cause malfunctions,
such as clogging the pump.
 State or local regulations on vola-
tile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle’s paint, wiper blades
or washer system.
CAUTION
 Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.

Maintenance and Service11
– CONTINUED –
11-27. Installation of Acces-soriesAlways consult your SUBARU dealer
before installing fog lights or any other
electrical equipment in your vehicle. Such
accessories may cause the electronic
system to malfunction if they are incor-
rectly installed or if they are not suited for
the vehicle. We recommend that you
install only genuine SUBARU accessories
on your vehicle.
11-28. Replacing Bulbs
■ HeadlightsThe LED headlight warning light illumi-
nates if the LED headlights malfunction.
Have your vehicle inspected at a
SUBARU dealer as soon as possible.■ Backup LightNOTEIt may be difficult to replace the
bulbs. We recommend that you have
the bulbs replaced by your SUBARU
dealer if necessary.
 If a genuine SUBARU accessory has
been installed to the rear bumper,
check the manual included with the
accessory.
WARNING
Bulbs may become very hot while
illuminated. Before replacing bulbs,
turn off the lights and wait until the
bulbs cool down, Otherwise, there
is the risk of sustaining a burn
injury.
CAUTION
 Before replacing a backup light,
stop the engine and allow the
exhaust pipes and surrounding
parts to cool suffi ciently. As the
bulbs are near the exhaust pipes,
there is a risk of being burned. Replace any bulb only with a new
bulb of the specified wattage.
Using a bulb of different wattage
could result in a fire. For the spec-
ified wattage of each bulb, refer to
"Bulb Chart" P387. For replace-
ment, contact your SUBARU
dealer.
