Checking tire inflation pressure
You should check tire inflation pressure every two weeks, or at least once a
month.Do not forget to check the spare.
WARNING
In order to ensure the performance of the tires, maintain proper tire inflation pressure.
If the tires are not properly inflated, the following may occur:
● 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
After inspecting and adjusting tire inflation pressure, make sure to install the tire valve
caps.
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.
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 drive train
If a tire needs frequent inflating, have it checked by your Lexus 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.
