Maintenance and care
LX570_OM_OM60L96U_(U) CAUTION■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs. ■
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause da mage to parts of the drive train, as well as dangerous
handling characteristics, which may lead to an accident resulting in death or serious
injury. ●
Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of re markably different treadwear.●
Do not use tire sizes other th an those recommended by Lexus.●
Do not mix differently constructed tires (r adial, bias-belted or bias-ply tires).●
Do not mix summer, all season and snow tires. ●
Do not use tires that have b een used on another vehicle.
Do not use tires if you do not know how they were used previously. ■
When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pr essure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

LX570_OM_OM60L96U_(U) NOTICE■
Repairing or replacing tires, wheels, tire pressure warning valves and transmit-
ters and tire valve caps ●
When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and
transmitter may be damaged if not handled correctly.●
Make sure to install the tire valve caps. If the tire valve caps are not installed,
water could enter the tire pr essure warning valves and the tire pressure warning
valves could be bound. ●
When replacing tire valve ca ps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.■
To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid seal ants, the tire pressu re warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact your Lexus
dealer or other qualified serv ice shop as soon as possible. Make sure to replace the
tire pressure warning valve and tran smitter when replacing the tire. (  P. 767)■
Driving on rough roads
Take particular care when driving on roads with loose su rfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition driv ing on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body. ■
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressu re gauge onto the tire valve.
Read the pressure using the gauge gradations.
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.
After completing the tire inflati on pressure measurement and
adjustment, apply soapy water to the valve and check for leak-
age.
Put the tire valve cap back on. STEP 1

Maintenance and care

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.

Maintenance and care
LX570_OM_OM60L96U_(U) Wheels If a wheel is bent, cracked or heavil y corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care shoul d be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and inset
* .
Replacement wheels are available at your Lexus dealer.
* : Conventionally referr ed to as “offset”.
Lexus does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
● Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or chan ging your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Lexus genuine balanc e weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
