The vehicle becomes lower when
driving with the compact spare tire
compared to when driving with
standard tires. Be careful when
driving over uneven road sur-
faces.
■Driving with tire chains and
the compact spare tire
Do not fit tire chains to the com-
pact spare tire. Tire chains may
damage the vehicle body and
adversely affect driving perfor-
mance.
■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.
■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 carrier 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 colli-
sion 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
●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 properly,
causing damage to the wheel or
the wire cable.
●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 low-
ered, contact your Toyota
