Make sure to maintain the proper tire inflation pressure.
Tire inflation pressure should be checked at least once per month. However, Toyota recommends that tire inflation pressure be checked once every two weeks.
Checking the specified tire inflation pressure
The recommended cold tire inflation pressure and tire size are displayed on the tire and loading information label.

Inspection and adjustment procedure

1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge onto the tire valve.
3. Read the pressure using the gauge gradations.
4. 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.
5. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage.
6. Put the tire valve cap back on.
â– 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.
â– Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
If a tire needs frequent inflating, have it checked by your Toyota dealer.
â– Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
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.
It is difficult to judge if a tire is properly inflated based only on its appearance.
WARNING
â– 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:
NOTICE
â– 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.
