6-3. Do-it-yourself maintenance

■

Repairing or replacing tires, wheels, tire pressure warning valve
and transmitters and tire valve caps

●

When removing or fitting the wheels, tires or the tire pressure warning

valve and transmitters, contact your Toyota dealer as the tire pressure

warning valve and transmitters may be damaged if not handled cor-

rectly.

●

Make sure to install the tire valve caps. If the tire valve caps are not

installed, water may enter the valves of the tire pressure warning valve

and transmitters and the valves may become stuck.

●

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 pressure warning valve and transmit-
ters
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 your Toyota dealer or other qualified service shop as soon

as possible. Make sure to replace the tire pressure warning valve and

transmitter when replacing the tire. (

→P. 446)

■

Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-

holes.

These conditions may cause losses in tire inflation pressure, reducing

the cushioning ability of the tires. In addition, driving on rough roads

may cause damage to the tires themselves, as well as the vehicle’s

wheels and body.

■

Low profile tires (vehicles with 18 or 19-inch wheels)
Low profile tires may cause greater damage than usual to the tire wheel

when sustaining impact from the road surface. Therefore, pay attention

to the following:

●

Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

●

Avoid potholes, uneven pavement, curbs and other road hazards. Fail-

ure to do so may lead to severe tire and wheel damage.

■

If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

6-3. Do-it-yourself maintenance

Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.

■

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.

■

Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:

●

Reduced fuel economy

●

Reduced driving comfort and poor handling

●

Reduced tire life due to wear

●

Reduced safety

●

Damage to the drivetrain

If a tire needs frequent inflating, 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 or 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.

It is difficult to judge if a tire is properly inflated based only on its appear-

ance.

●

It is normal for the tire inflation pressure to be higher after driving as

heat is generated in the tire. Do not reduce tire inflation pressure after

driving.

●

Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is

balanced.

WARNING

■

Proper inflation is critical to save tire performance
Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur

which could lead to an accident resulting in death or serious injury:

●

Excessive wear

●

Uneven wear

●

Poor handling

●

Possibility of blowouts resulting from overheated tires

●

Air leaking from between tire and wheel

●

Wheel deformation and/or tire damage

●

Greater possibility of tire damage while driving (due to road hazards,

expansion joints, sharp edges in the road, etc.)

NOTICE

■

When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or moisture may get into the valve and

cause an air leak, resulting in decreased tire inflation pressure.
