NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valves and transmitters

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 trans-

mitter 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 pressure warning valves and the tire pressure warning valves

could be bound.

●

When replacing tire valve caps, do not use tire valve caps other than those specified.

The cap may become stuck.

■

To avoid damage to the tire pressure warning valves and transmitters

When a tire is repaired with liquid sealants, the tire pressure warning valve and trans-

mitter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or

other qualified service shop as soon as possible. Make sure to replace the tire pressure

warning valve and transmitter when replacing the tire. (

■

Driving on rough roads

Take particular care when driving on roads with loose surfaces or potholes.

These conditions may cause losses in tire inflation pressure, reducing the cushioning

ability of the tires. In addition driving 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 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 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 and 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.

It is difficult to judge if a tire is properly inflated based only on its appearance.

●

It is normal for the tire inflation pressure to be higher after driving as heat is generated

in the tire. Do not reduce tire inflation pressure after driving.

●

Never exceed the vehicle capacity weight.

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

502

WARNING

■

Proper inflation is critical to save tire performance

Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur which could

lead to an accident resulting in death or serious injury:

●

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

■

When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

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.

503

Main

Wheels

When replacing wheels, care should 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 referred to as “offset”.

Lexus does not recommend using the following:

●

Wheels of different sizes or types

●

Used wheels

●

Bent wheels that have been straightened

●

Use only Lexus wheel nuts and wrenches designed for use with your alumi-
num wheels.

●

When rotating, repairing or changing 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 balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.

■

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and transmit-

ters that allow the tire pressure warning system to provide advance warning in the event

of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning

valves and transmitters must be installed. (



P. 491)

If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.

WARNING

■

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 a 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 accident.

NOTICE

■

Replacing tire pressure warning valves and transmitters

●

Because tire repair or replacement may affect the tire pressure warning valves and

transmitters, make sure to have tires serviced by your Lexus dealer or other qualified

service shop. In addition, make sure to purchase your tire pressure warning valves

and transmitters at your Lexus dealer.

●

Ensure that only genuine Lexus wheels are used on your vehicle.

Tire pressure warning valves and transmitters may not work properly with non-genu-

ine wheels.
