■When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings has 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 pressure
warning light does not flash 3 times.
● After driving for a certain period of time since the initialization has been
completed, the tire pressure warning light comes on after blinking for 1
minute.
■ 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.
■ Maximum load of tire
Check that the maximum load of the replaced tire is greater than 1/2 of \
the
Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle,
whichever is greater.
For the maximum load of the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire, and for the Gross
Axle Weight Ratings (GAWR), see the Certification Label. ( P. 313, 409).

Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for driv-
ing on snow-covered or icy roads. Fo r driving on snow-covered roads or
icy roads, the use of snow tires is recommended. When installing snow
tires, be sure to replace all four tires.
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 perfor-
mance 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.
3 Snow 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, construc-
tion and load capacity as the originally 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 restrictions. Snow tires should be installed on
all wheels. ( P. 166)
■ Initializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified
level.

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 handling characteristics, which may lead to fatal accidents or
injury.
●Do not mix tires of different makes, models, tread patterns or treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix 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 press the tire pressure warning reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even 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 and tire pressure warning valves
and transmitters
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 correctly.
■ To avoid damaging the tire pressure warning valves and transmitters
Do not use liquid sealants on flat tires.
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire air pressure, reducing the cush-
ioning ability of the tires. In addition driving on rough roads may cause dam-
age 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.

■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once a
month.
Do not forget to check the spare tire.
■ 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 at the recommended
level, adjust the pressure.
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.

Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may 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 refilling, 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 misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
● 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.

CAUTION
■Proper inflation is criti cal 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 resulting 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 adjust ing tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture 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.
