Maintenance and care
LX570_OM_OM60L96U_(U) ■
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 ti re inflation pressure
Driving with incorrect tire inflation pressure may result in the following:●
Reduced fuel efficiency ●
Reduced driving comfort and tire life ●
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. ●
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure
that is even just a few pounds off can affect ride quality and handling.●
Do not reduce tire inflation pressure afte r driving. It is normal for tire inflation
pressure to be higher after driving. ●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

7784-3. Do-it-yourself maintenance
LX570_OM_OM60L96U_(U) CAUTION■
Proper inflation is critical to save tire performance
Keep your tires properly in flated. Otherwise, the following conditions may occur
and result in an accident causing death or serious injury: ●
Excessive wear ●
Uneven wear ●
Poor handling ●
Possibility of blowouts resu lting from overheated tires●
Poor sealing of the tire bead ●
Wheel deformation and/ or tire separation●
A greater possibility of tire damage from road hazards
NOTICE■
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture co uld get into the valve and cause air leak-
age, which could result in an accident. If the caps have been lost, replace them as
soon as possible.

When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire
pressure warning valves and tran smitters must be installed. (  P. 767)
CAUTION■
When replacing wheels ●
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.●
Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident , causing death or serious injury.■
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an acci-
dent.
NOTICE■
Replacing tire pressure warning valves and transmitters ●
Because tire repair or re placement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Le xus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitte rs at your Lexus dealer.●
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valv es and transmitters may not work properly with non-
genuine wheels.
