WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down

over painted parts. The alcohol
contained in the engine coolant

Maintenance and service
Aluminum wheelsAluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
. When any of the wheels are removed
and replaced for tire rotation or to change
a flat tire, always check the tightness of
the wheel nuts after driving approximately
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.
. When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels.
