Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cann
ot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warni ng system will not work properly. After
about 20 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.

■When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings has not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by your Toyota dealer.
● When operating the tire pressure warning reset switch, the tire pressure
warning light does not flash 3 times.
● After driving for a certain period of time since the initialization has been
completed, the tire pressure warning light comes on after blinking for 1
minute.
■
Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the maximum load of the re placed tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
For the maximum load of the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire, and for the Gross
Axle Weight Ratings (GAWR), s ee the Certification Label. (→P. 313,
409).

Maintenance and care
CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as
dangerous handling characteristics, wh
ich may lead to fatal accidents or
injury.
●Do not mix tires of different makes, models, tread patterns or tread-
wear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix radial, bias-belted, or bias-ply tires.
●Do not mix summer, all season and winter tires.
■When initializing the tire pressure warning system
Do not press the tire pressure warnin g reset switch without first adjusting
the tire inflation pressure to the spec ified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually normal.

■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacing. ( →P. 336)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
