Maintenance and care
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust t
he tire inflation pressure to the speci-
fied 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 follow-
ing cases, the settings have not b een 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 pres-
sure warning light doe s not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.

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 han-
dling characteristics, which may lead  to an accident resulting in death or
serious injury.
●Do not mix tires of different ma kes, models or tread patterns. 
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed ti res (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and winter tires.
●Do not use tires that have been used on another vehicle.
●Do not use tires if you do not know how they were used previously.
■When initializing the tire  pressure warning system
Do not push 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 ev en if the tire inflation pressure is
low, or it may come on when the tire  inflation pressure is actually normal.

NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●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 cor-
rectly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■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. 423)
■Driving on rough roads
Take particular care when driving  on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■If tire inflation pressures  become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Inspection and adjustment procedure
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the graduations of the gauge.
If the tire inflation pressure is not within the recommended
levels, adjust inflate the tire.
If you add too much air, pres s the center of the valve to
lower.
After completing the tire inflation pressure measurement
and adjustment, apply soapy water to the valve and check
for leakage.
Reinstall the tire valve cap.

■Tire inflation pressure check interval
You should check tire pressure every two weeks, or at least once a
month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure ma y result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent re filling, have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or  1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be mi sleading. In addition, tire infla-
tion pressures that are even just a few pounds off can degrade ride
and handling.
●Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

Maintenance and care
CAUTION
■Proper inflation is critical
 to save tire performance
Keep your tires properly inflated.
Otherwise, the following conditions may occur and result in an accident
causing death or serious injury.
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resu lting from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or mo isture could get into the valve and
cause air leakage, which could result  in an accident. If the caps have
been lost, replace them as soon as possible.
