Rubber gaskets
3. After refilling the reserve tank and the radiator, reinstall the caps
and check that the rubber gaskets inside the radiator cap are in the
proper position. Changing the coolant
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
Change the engine coolant using the following procedures according
to the maintenance schedule in the “Warranty and Maintenance Book-
let”. 1. Remove the under cover.
2. Place a proper container under the drain plug and loosen the drainplug.

2. Pull out the dipstick, wipe it clean, and insert it again.
3. Pull out the dipstick again and check the oil level on it. If it is below
the lower level, add oil through the dipstick hole to bring the level upto the upper level. Recommended grade and viscosity
Each oil manufacturer has its own base oils and additives. Never use

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.

Aluminum wheels
Aluminum wheels can be scratched and damaged easily. Handle them
carefully to maintain their appearance, performance, and safety. When any of the wheels is removed and replaced for tire rotation or to
change a flat, always check the tightness of the wheel nuts after driving
approximatly 600 miles (1,000 km). If any nut is loose, tighten it to the
specified torque. Never apply oil to the threaded parts, wheel nuts, or tapered surface
of the wheel. Never let the wheel rub against sharp protrusions or curbs.
Be sure to fit tire chains on uniformly and completely around the tire,
otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be
sure to replace them with genuine SUBARU parts designed for aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If the level is low, fill
the fluid up to the neck of the reservoir.Use windshield washer fluid. If windshield washer fluid is unavailable use
clean water.
In areas where water freezes in winter, use an anti-freeze type windshield
washer fluid. SUBARU Windshield Washer Fluid contains 58.5% methyl
alcohol and 41.5% surfactant, by volume. Its freezing temperature varies
according to how much it is diluted, as indicated below.
