■ Allow inspection and repairs to be performed by a Toyota dealer
● Toyota technicians are well-trained specialists and are kept up to date
with the latest service information. They are well informed about the
operations of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly
take care of it.
CAUTION
■Warning in handling of battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
● Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of Califor-
nia to cause cancer and birth defects or other reproductive harm. Avoid

Maintenance and care
Push and hold the tire pressure
warning reset switch until the
tire pressure warning light blinks
slowly 3 times.
Wait for several minutes with the engine switch on, and then
turn the engine switch to the ACC or LOCK position.
Registering ID codes The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■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 c annot 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.

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.
