Washing the underbody
Chemicals, salts and gravel used for deicing road surfaces are ex-
tremely corrosive, accelerating the corrosion of underbody compo-nents, such as the exhaust system, fuel and brake lines, brakecables, floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside of the fenders with luke-
warm or cold water at frequent intervals to reduce the harmful effectsof such agents. Using a warm water washer
Keep a good distance of 12 in (30 cm) or more between the wash-
er nozzle and the vehicle. Do not wash the same area continuously.
If a stain will not come out easily, wash by hand. Some warm water
washers are of the high temperature, high pressure type, and they
can damage or deform the resin parts such as mouldings, or causewater to leak into the vehicle.
Waxing and polishing
Always wash and dry the vehicle before waxing and polishing.
Use a good quality polish and wax and apply them according to the
manufacturer’ s instructions. Wax or polish when the painted surface is
cool.
Be sure to polish and wax the chrome trim, as well as the painted sur-
faces. Loss of wax on a painted surface leads to loss of the original lus-
ter and also quickens the deterioration of the surface. It is recommendedthat a coat of wax be applied at least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has diminished to the point where the lus-
ter or tone cannot be restored, lightly polish the surface with a fine-
grained compound. Never polish just the affected area, but include the
surrounding area as well. Always polish in only one direction. A No. 2000
grain compound is recommended. Never use a coarse-grained com-
pound. Coarser grained compounds have a smaller grain-size numberand could damage the paint. After polishing with a compound, coat with

10-6Before the beginning of winter, check the condition of underbody
components, such as the exhaust system, fuel and brake lines, brake
cables, suspension, steering system, floor pan, and fenders. If any of
them are found to be rusted, they should be given an appropriate rust
prevention treatment or should be replaced. Contact your SUBARU
dealer to perform this kind of maintenance and treatment if you needassistance. Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt accumulation under
the floor mats because that could cause corrosion. Occasionally
check under the mats to make sure the area is dry.
Keep your garage dry. Do not park your vehicle in a damp, poorly
ventilated garage. In such a garage, corrosion can be caused by
dampness. If you wash the vehicle in the garage or put the vehicle
into the garage when wet or covered with snow, that can causedampness.
If your vehicle is operated in cold weather and/or in areas where road
salts and other corrosive materials are used, the door hinges and
locks, trunk lid lock, and hood latch should be inspected and lubri-
cated periodically.
Cleaning the interior
Use a vacuum cleaner to get rid of the dust and dirt. Wipe the vinyl areas with a clean, damp cloth. Seat fabric
Remove loose dirt, dust or debris with a vacuum cleaner. If the dirt is
caked on the fabric or hard to remove with a vacuum cleaner, use asoft blush then vacuum it.
Wipe the fabric surface with a tightly wrung cloth and dry the seat
fabric thoroughly. If the fabric is still dirty, wipe using a solution of mild
soap and lukewarm water then dry thoroughly.
If the stain does not come out, try a commercially-available fabric

Abnormally high tire pressure (tread worn in center)
HSB013AA
Ride comfort is poor. Also, the tire magnifies the effects of road-sur-
face bumps and dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for the vehicle when fully loaded
and for the vehicle when towing a trailer, adjust the tire pressures to the
values that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould lead to an accident.
Wheel balance
Each wheel was correctly balanced when your vehicle was new, but the
wheels will become unbalanced as the tires become worn during use.
Wheel imbalance causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle ’s straight-line stability. It
can also cause steering and suspension system problems and abnormal
tire wear. If you suspect that the wheels are not correctly balanced, have
them checked and adjusted by your SUBARU dealer. Also have them
adjusted after tire repairs and after tire rotation.

NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the vehicle
’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. Wear indicators
Each tire incorporates a tread wear indicator, which becomes visible
when the depth of the tread grooves decreases to 0.063 in. (1.6 mm). A
tire must be replaced when the tread wear indicator appears as a solid
band across the tread.
OM-H0231
WARNING
When a tire ’s tread wear indicator becomes visible, the tire is
worn beyond the acceptable limit and must be replaced immedi-
ately. With a tire in this condition, driving at high speeds in wetweather can cause the vehicle to hydroplane. The resulting lossof vehicle control can lead to an accident.
NOTE
For safety, inspect the tire tread regularly and replace the tires be- fore their tread wear indicators become visible. A) New tread
B) Worn tread
