- Tire inflation pressure check interval
You should check tire inflation pressure every 2 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: l Reduced fuel efficiency
l Reduced driving comfort and tire life
l Reduced safety
l Damage to the drive train

If a tire needs frequent refilling, have it checked by your Lexus dealer.

- Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following: l 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.

l 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.

l Do not bleed or reduce tire inflation pressure after driving. It is normal for the tire inflation pressure to be higher after driving.

l Never exceed the vehicle capacity weight.

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


- Proper inflation is critical 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.

l Excessive wear
l Uneven wear l Poor handling
l Possibility of blowouts resulting from overheated tires
l Poor sealing of the tire bead
l Wheel deformation and/or tire separation
l A greater possibility of tire damage from road hazards


- When inspecting and adjusting 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
