2-9. Driving Tips
■Use snow tires on all four wheels
Do not go faster than 75 mph (120 km/h) while driving with snow
tires. Inflate snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more than rec-
ommended on the tire pressure label (driver’s door frame), but
never more than the maximum cold-tire pressure shown on the
tires.
The vehicle is originally equipped with all season radials desi gned
to be used all year around. In some extreme climates you may fi nd
it necessary to replace them wit h snow tires during the winter
months to further improve tracti on on snow and ice covered road s.
Check local regulations before using tire chains.
Install the chains on the front tires only.
Do not use chains o n the rear tires.
Please consult your Toyota dealer.
■Installing the chains
If your vehicle is equipped with wheel covers remove them, oth-
erwise the chain bands will scratch them.
Secure the chains on the front tires as tightly as possible.
Always follow the chain manuf acturer’s instructions.
Retighten the chains after dri ving 1/4—1/2 mile (1/2—1 km).
If your vehicle is equipped with the tire pressure monitoring s ystem, the
system may not function correctly when using tire chains.
Snow Tires
WARNING
■Use only the same size and type tires (snow, radial, or non-rad ial)
on all four wheels
Using tires different in size or type is dangerous. Your vehicl e’s handling
could be greatly affected and result in an accident.
NOTICE
Check local regulations before using studded tires.

3-12. Tire Pressure Monitoring System
Tire Pressure Monitoring System
The system monitors the tire pres-
sures indirectly using the data
sent from the ABS wheel speed
sensors.
To allow the system to operate correctly, the system needs to be ini-
tialized with the specified tire pressure (value on the tire pressure
label). Follow the procedure and perform the initialization.
Refer to Tire Pressure Monitorin g System Initialization on P. 233.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on P. 162.
: If equipped
The Tire Pressure Monitoring S ystem (TPMS) monitors the air
pressure of all four tires. If the air pressure of one or more tires
is too low, the system warns the driver by indicating the tire
pressure monitoring system warning light in the combination
meter and operating a beep sound.

When Driving
In the following cases, system i nitialization must be performed so that
the system operates normally. • A tire pressure is adjusted.
• Tire rotation is performed.
• A tire or wheel is replaced.
• The battery is replaced or completely drained.
• The tire pressure m onitoring system warning light is illuminated.
■Initialization method
Park the car in a safe place and firmly apply the parking brake.
Let the tires cool, then adjust the tire pressure of all four (4) tires
to the specified pressure indicated on the tire pressure label
located on the door jamb of t he driver’s door (door open).
Refer to Tires on P. 582.
Switch the ignition ON.
While the vehicle is parked,
press and hold the tire pres-
sure monitoring system set
switch and verify that the tire
pressure monitoring system
warning light in the combina-
tion meter flashes twice and
a beep sound is heard once.
Tire Pressure Monitoring System Initialization

NOTICE
If the system initialization is performed without adjusting the tire pres-
sure, the system cannot detect th e normal tire pressure and it may not
illuminate the tire pre ssure monitoring system warning light ev en if a tire
pressure is low, or it may illuminate the light even if the pre ssures are
normal.
Adjust the tire pressure on all four tires and initialize the s ystem when
the warning light is turned on. If the warning light turns on f or a reason
other than a flat tire, the tire pressure of all four tires may have
decreased naturally.
The system initialization will not be performed if the switch i s pressed
while the vehicle is being driven.
