Replacement of brake pad and lining
The front disc brakes and the right rear disc brake have an audible wear indicators on the brake pads. If the brake pads wear close to their service limit,
the wear indicator makes a very audible scrapingnoise when the brake pedal is applied.
If you hear this scraping noise each time you apply the brake pedal, have the brake pads serviced byyour SUBARU dealer as soon as possible.
CAUTION
If you continue to drive despite the scraping noise from the audible brake pad wear indica-
tor, it will result in the need for costly brake rotor repair or replacement.
Breaking-in of new brake pads and linings
When replacing the brake pad or lining, use only
genuine SUBARU parts. After replacement, the new
parts must be broken in as follows:
Brake pad and lining
While maintaining a speed of 30 to 40 mph (50 to 65
km/h), step on the brake pedal lightly. Repeat this
five or more times.
Parking brake lining

WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely and to rapidly become hot. A sharp
increase in temperature could cause tread
separation, and destruction of the tires. The resulting loss of vehicle control could lead toan accident.
Wheel balance
Each wheel was correctly balanced when your ve-
hicle was new, but the wheels will become unbal-
anced as the tires become worn during use. Wheel
imbalance causes the steering wheel to vibrate
slightly at certain vehicle speeds and detracts fromthe vehicle ’s straight-line stability. It can also cause
steering and suspension system problems and ab-
normal tire wear. If you suspect that the wheels are
not correctly balanced, have them checked and ad-
justed by your SUBARU dealer. Also have them ad-
justed after tire repairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the ve-
hicle’ s running stability. Contact your SUBARU dealer if you notice abnormal tire wear.
* : The suspension system is designed to hold each wheel
at a certain alignment (relative to the other wheels and to
the road) for optimum straight-line stability and cornering
performance.

Before beginning work on or near any bat-
tery, be sure to extinguish all cigarettes,
matches, and lighters. Never expose a batteryto an open flame or electric sparks. Batteriesgive off a gas which is highly flammable andexplosive. For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a
battery. Do not let battery fluid contact eyes, skin,
fabrics, or paint because battery fluid is a cor- rosive acid. If battery fluid gets on your skin or in your eyes, immediately flush the area
with water thoroughly. Seek medical help im-
mediately if acid has entered the eyes.If battery fluid is accidentally swallowed,
immediately drink a large amount of milk or
water, and seek medical attention immediately. To lessen the risk of sparks, remove rings,
metal watchbands, and other metal jewelry.
