Check the clutch pedal free play and reserve distance according to the
maintenance schedule in the “Warranty and Maintenance Booklet ”.

1. With the engine idling, check that there are no abnormal noises
when the clutch pedal is depressed, and that shifting into 1st or re-
verse feels smooth.
2. Start the vehicle by releasing the pedal slowly to check that the en-gine and transmission smoothly couple without any sign of slippage. Checking the clutch pedal free play

tighten it to the specified torque.
Aluminum wheels (if equipped)
Aluminum wheels can be scratched and damaged easily. Handle them
carefully to maintain their appearance, performance, and safety.
When any of the wheels is removed and replaced for tire rotation or to
change a flat, always check the tightness of the wheel nuts after driving
approximatly 600 miles (1,000 km). If any nut is loose, tighten it to the
specified torque. Never apply oil to the threaded parts, wheel nuts, or tapered surface
of the wheel. Never let the wheel rub against sharp protrusions or curbs.
Be sure to fit tire chains on uniformly and completely around the tire,
otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be
sure to replace them with genuine SUBARU parts designed for aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If the level is low, fill
the fluid up to the neck of the reservoir.Use windshield washer fluid. If windshield washer fluid is unavailable use
clean water.
In areas where water freezes in winter, use an anti-freeze type windshield
washer fluid. SUBARU Windshield Washer Fluid contains 58.5% methyl
alcohol and 41.5% surfactant, by volume. Its freezing temperature varies
according to how much it is diluted, as indicated below.

11-52It is unnecessary to periodically check the battery fluid level or periodi-
cally refill with distilled water. Fuses
CAUTION
Never replace a fuse with one having a higher rating or with mate-
rial other than a fuse because serious damage or a fire could re-sult.
HBB008DA HB8003CA
The fuses are designed to melt during an overload to prevent damage to
the wiring harness and electrical equipment. The fuses are located intwo fuse boxes. One is located under the instrument panel behind the
coin tray on the driver’s seat side. The other one is housed in the engine
compartment. The fuse puller and spare fuses are stored in the main
fuse box cover in the engine compartment.
If any lights, accessories or other electrical controls do not operate, in-
spect the corresponding fuse. If a fuse has blown, replace it.
