Maintenance and care
Vehicles with a full-size spare tire
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a warning light.
( P.515)
■Routine tire inflation pressure
checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily vehicle checks.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate
properly. • If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio
wave signals is installed. • If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings. • If the tire inflation pressure is
extremely higher than the specified
level. • If tires not equipped with tire pressure
warning valves and transmitters are
used. • If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis- play, airport or other facility that gen-
erates strong radio waves or electrical
noise. • When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device.
●When the vehicle is parked, the time
taken for the warning to start or go off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the tire pressure does not reach a low
enough level, or if the pressure is higher

than the pressure th at was adjusted to
when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.484)
■Replacing tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis-
tered, the tire pre ssure warning system
will not work properly. After driving for about 10 minutes, the tire pressure
warning light blinks for 1 minute and
stays on to indicate a system malfunc- tion.

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 valves and transmitters,
contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer as the tire pressure warning valves
and transmitters may be damaged
if not handled correctly.
●Make sure to install the tire valve
caps. If the tire valve caps are not installed, water could enter the tire
pressure warning valves and the
tire pressure warning valves could be bound.
●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 pres-
sure warning valves and trans- mitters
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 any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer as soon as possible.
Make sure to replac e the tire pressure warning valve and transmitter when

Maintenance and care
■The tire pressure warning sys-
tem must be init ialized in the
following circumstances:
 When rotating front and rear tires
which have different tire inflation
pressures.
 When changing the tire size.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
 When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized , the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system
1 Park the vehicle in a safe place
and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
2 Adjust the tire inflation pressure
to the specified co ld tire inflation
pressure level. ( P.573)
Make sure to adjust the tire pressure to
the specified cold tire inflation pressure level. The tire pre ssure warning system
will operate based on this pressure
level.
3 Turn the engine switch to ON.
4 Press or of the meter
control switch to select .
5 Press or to select “Vehi-
cle Settings” and then press and

until the tire pressure warn-
ing light blinks 3 times.
■Initialization procedure
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initialization, it
is not necessary to press the reset switch again as initialization will
restart automatically when the engine
switch is turned to ON the next time.
●If you accidentally press the reset
switch when initialization is not neces- sary, adjust the tire inflation pressure
