1. Power Steering Fluid Reservoir
Check your power steering fluid level
monthly. The power steering fluid
expands greatly as its temperature rises
and the fluid level differs according
to fluid temperature. Therefore, the
reservoir tank has two different checking
ranges for hot and cold fluid. Please
refer to your Owner's Manual for details.
2. Air Cleaner Element
This element filters intake air. Follow
the maintenance guidelines in your
"Warranty and Maintenance" booklet.
When necessary, replace this element
with a genuine Subaru air cleaner.
3. Radiator Cap
If your engine overheats, safely pull
off the road and stop your vehicle in a
safe place. Never attempt to remove
the radiator cap until the engine has
been shut off and has fully cooled
down. If steam is coming from the
engine compartment, turn the engine
off and move everyone away from
the vehicle until it cools. Please refer
to your Owner's Manual for details.

4. Engine Oil Dipstick
Check the engine oil level at each fuel
stop. Pull out the dipstick, wipe it clean,
and insert it again. Pull it out and check
the oil level. If it is below the lower
level, add oil to bring the level up to
the upper level. (Use only engine oil of
the recommended grade and viscosity.
Please refer to your Owner's Manual
for oil recommendations and other
important details.)
5. Engine Coolant Reservoir
Check your coolant level at each fuel
stop. Observe the coolant level on
the outside of the reservoir while the
engine is cool. If the level is close
to – or lower than – the "LOW" level
mark, add coolant to the "FULL"
level mark. If the reserve tank is
empty, remove the radiator cap and
refill as required. Please refer to
your Owner's Manual for details.
