To check belt tension, place a straightedge (ruler) across two adja-
cent pulleys and apply a force of 22 lb (98 N, 10 kg) midway betweenthe pulleys by using a spring scale. Belt deflection should be the
amount specified. 3.0 liter models
It is unnecessary to check belt tension periodically because your

tomatic transmission fluid up to the upper level. n Checking the fluid level when the fluid is cold
When the fluid level has to be checked without time to warm up the
automatic transmission, check to see that the fluid level is betweenthe lower level and upper level on the “COLD” range. If it is below that
range, add fluid up to the upper level. Be careful not to overfill. Recommended fluid

Checking the gear oil level CAUTION
If the vehicle requires frequent refilling, there may be an oil leak. If you suspect a problem, have the vehicle checked at your
SUBARU dealer.

Power steering fluid
Checking the fluid level
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 allow any dirt into the tank. And never use
different brands together. Avoid spilling fluid when adding it in the tank.
The power steering fluid expands greatly as its temperature rises; the
fluid level differs according to fluid temperature. Therefore, the reser-
voir tank has two different checking ranges for hot and cold fluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop the engine.
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run: Check that the oillevel is between “HOT MIN ” and “HOT MAX ” on the surface of the
reservoir tank.

When adding brake fluid, be careful not to allow any dirt into
the reservoir. Never splash the brake fluid over painted surfaces or rubber
parts. Alcohol contained in the brake fluid may damage them.
Check the fluid level monthly.

Brake booster
If the brake booster does not operate as described below, have it
checked by your SUBARU dealer.

the same pedal force each time. The distance the pedal travels should
not vary.
2. With the brake pedal depressed, start the engine. The pedal should
move slightly down to the floor.
3. With the brake pedal depressed, stop the engine and keep the pedal
depressed for 30 seconds. The pedal height should not change.
4. Start the engine again and run for about one minute then turn it off.
Depress the brake pedal several times to check the brake booster.
