2006 Lexus GX 470 Owners Manual - Page 549

CHASSIS The recommended cold tire inflation pressures, tire sizes and the combined weight of occupants and cargo (vehicle capacity weight) are described on page 520 and 564. They are also described on the tire and loading information label as shown. You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare! The following instructions for checking inflation pressure should be observed: tire D Always use a tire pressure gauge. The appearance of a tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can degrade handling and ride. D Do not bleed or reduce tire inflation pressure after driving. It is normal for the tire inflation pressure to be higher after driving. D Never exceed the vehicle capacity weight. Passengers and luggage weight should be located so that the vehicle is balanced. D The pressure should be checked 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 1.5 km or 1 mile since, you will get an accurate cold tire inflation pressure reading. D If you cannot adjust the tire pressure when the tires are cold, add 20 kPa (0.2 kgf/cm2 or bar, 2.9 psi) to 30 kPa (0.3 kgf/cm2 or bar, 4.3 psi) more to the front tires and rear tires than the cold tire pressure, but never exceed the maximum cold tire pressure molded on the tire sidewall. 524
