Exterior care Washing
The best way to preserve your vehicle ’s beauty is
frequent washing. Wash the vehicle at least once a
month to avoid contamination by road grime.
Wash dirt off with a wet sponge and plenty of luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as
required. If you use a light detergent, make certain
that it is a neutral detergent. Do not use strong soap or chemical detergents. All cleaning agents should
be promptly flushed from the surface and not al-
lowed to dry there. Rinse the vehicle thoroughly with
plenty of lukewarm water. Wipe the remaining water
off with a chamois or soft cloth. NOTE When having your vehicle washed in an auto- matic car wash, make sure beforehand that thecar wash is of suitable type. If the vehicle is
equipped with a rear/roof spoiler or rear wiper, itmay be damaged by car wash brushes or otherequipment.
CAUTION
When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drivethe vehicle at a safe speed while lightly press- ing the brake pedal to heat up the brakes. Do not wash the engine compartment and
area adjacent to it. If water enters the engineair intake, electrical parts or the power steer-
ing fluid reservoir, it will cause engine trouble
or faulty power steering respectively.
Washing the underbody
Chemicals, salts and gravel used for deicing road
surfaces are extremely corrosive, accelerating the
corrosion of underbody components, such as theexhaust system, fuel and brake lines, brake cables,floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside of the
fenders with lukewarm or cold water at frequent in-
tervals to reduce the harmful effects of such agents.
Using a warm water washer
Keep a good distance of 12 in (30 cm) or more
between the washer nozzle and the vehicle.

Recommended grade and viscosity
Each oil manufacturer has its own base oils and ad-
ditives. Never use different brands together.
Oil grade: API classification GL-5
SAE viscosity No. and Applicable Temperature Power steering fluid
Checking the fluid level
1) Reservoir tank
The power steering fluid expands greatly as its tem-
perature rises; the fluid level differs according to
fluid temperature. Therefore, the reservoir tank has
two different checking ranges for hot and coldfluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop theengine.

1) Specified range
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run:Check that the oil level is between “HOT MIN ” and
“ HOT MAX ” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check that the oil level is between “COLD MIN ” and
“ COLD MAX ” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary to bring the level between the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indicate pos-
sible leakage. Consult your SUBARU dealer for in- spection.
WARNING
Be careful not to burn yourself because the fluid may be hot.
CAUTION

When power steering fluid is being added,
use only clean fluid, and be careful not to al- low any dirt into the tank. And never use dif-
ferent brands together. Avoid spilling fluid when adding it in the
tank.
