WARNING
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power
back door main switch ( →P. 133). Failure to do so may cause the back
door to operate unintentionally if the power back door switch is acciden-
tally touched, resulting in hands and fingers being caught and injured.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the po ssibility of personal injury during a
collision or sudden braking.
NOTICE
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standa rd tires. Be careful when driving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmit-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( →P. 524)

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 clam p 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 redu ces 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.
