NOTICE
■When stowing the flat tire
●Ensure that there is no object caught between the tire and the vehicle
underbody.
●Securely tighten the spare tire clamp bolt to hold the spare wheel car-
rier by the hook.
●Stow the flat tire in the spare tire location. Failure to do so may cause
damage to the spare tire carrier. Proper storage reduces the possibility
of injury in a collision or during sudden braking.
●Have the flat tire repaired and the spare tire replaced with it as soon as
possible.
■Proper storage of the spare tire
●Do not attempt to turn the spare tire clamp bolt without a tire on the
hoist assembly, as doing so may cause the wire cable to slip off of the
shaft inside the unit and the wire cable may not be able to be raised or
lowered. If the spare tire clamp bolt has been turned without a tire on
the hoist assembly and the wire cable cannot be raised or lowered,
contact your Toyota dealer.
●If the hoist assembly is slanted when
stowing a tire, the hoist assembly may
become stuck in the wheel opening
and the tire may not be raised prop-
erly, causing damage to the wheel or
the wire cable.
