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.
