Maintenance and care
2 All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 267)
■Initializing the tire pressure warning system
Initialize the tires with the tire inflat ion pressure adjusted to the specified
level.
■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 seve ral minutes. However, in the fol-
lowing cases, the settings have 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 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 and then stays on after driving for about
20 minutes.

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 makes, 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.

5-2. Steps to take in an emergency
*1: Open door warning buzzer:
The buzzer sounds to indicate that any door is opened (with the vehicle hav-
ing reached a speed of 3 mph [5 km/h])
*4
(U.S.A.) Maintenance required
reminder light
Indicates that mainte-
nance is required accord-
ing to the driven distance
on the maintenance
schedule.
*6
Illuminates for about 3
seconds and then flashes
for about 15 seconds
approximately 4500 miles
(7200 km) after the main-
tenance data has been
reset. If necessary, perform
maintenance.
Comes on and remains on
if the distance driven
exceeds 5000 miles (8000
km) after the maintenance
data has been reset.
(The indicator will not
work properly unless the
maintenance data has
been reset.) Perform the necessary
maintenance.
Please reset the main-
tenance data after the
maintenance is per-
formed. (P. 533)

■
Front passenger detection sensor and passenger seat belt reminder
If luggage or other load is placed on the right front passenger seat, depend-
ing on its weight, the reminder light to flash and buzzer to sound.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after several minutes).
■When a tire is replaced with a spare tire
The temporary spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the temporary spare
tire. Replace the temporary spare tire with the repaired tire and adjust
the proper tire inflatio n pressure. The tire pres sure warning light will turn
off after several minutes.
■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.

maintenance is per-
formed. (P. 533)
Comes on approximately
5000 miles (8000 km) after

5-2. Steps to take in an emergency
Stowing the flat tire, jack and all tools
Remove the center wheel ornament by pushing from the
reverse side. Lay down the tire with the outer
side facing up, and install the
holding bracket.
Fasten the claws of the holding
bracket into the wheel holes as
shown in the illustration.
Holding bracket
Claw
Then secure the tire, taking care that the tire goes straight up
without catching on any other part , to prevent it from flying for-
ward during a collisio n or sudden braking.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warning system must be reset. (P. 558)
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warn-
ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.
