NOTICE
■Be careful when driving over bumps with the compact spare tire installed on the vehi-
cle
When driving with the compact spare tire installed, the vehicle height will be different
than when driving with standard tires. Be careful when driving over uneven road sur-
faces, etc.
■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 trans-
mitter, contact your Lexus dealer as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.
■When stowing the flat tire (RX450hL)
●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 possibilit y 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 (RX450hL)
●If the spare tire clamp bolt is turned withou t a tire on the hoist assembly, the wire cable
may not be able to be lowered. If the wire cable cannot be lowered, contact your
Lexus 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 properly, causing damage to the wheel
or the wire cable.
