WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 89 ft•lbf (120
N•m, 12.2 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifi-
cally designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut
threads or bolt holes of the wheel, have the vehicle inspected by
your SUBARU dealer.
• When installing the wheel nuts, be sure to install them with the
tapered ends facing inward. (oP. 362)
