Lexus ES: Tires

Replace or rotate tires in accordance with maintenance schedules and treadwear.

Checking tires

Check if the treadwear indicators are showing on the tires. Also check the tires for uneven wear, such as excessive wear on one side of the tread.

Check the spare tire condition and pressure if not rotated.

  1. New tread
  2. Worn tread
  3. Treadwear indicator

The location of treadwear indicators is shown by a "TWI" or " " mark, etc., molded into the sidewall of each tire.

Replace the tires if the treadwear indicators are showing on a tire.

■When to replace your vehicle's tires

If you are not sure, consult your Lexus dealer.

■Tire life Any tire over 6 years old must be checked by a qualified technician even if it has seldom or never been used or damage is not obvious.

■Low profile tires (18-inch tires) Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when compared to standard tires. Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather conditions.

■Maximum load of tire Check that the maximum load of the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater.

For the GAWR, see the Certification Label.

For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire.

■Tire types

■If the tread on snow tires wears down below 0.16 in. (4 mm) The effectiveness of the tires as snow tires is lost.

WARNING

■When inspecting or replacing tires Observe the following precautions to prevent accidents.

Failure to do so may cause damage to parts of the drivetrain as well as dangerous handling characteristics, which may lead to an accident resulting in death or serious injury.

NOTICE

■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.

■Low profile tires (18-inch tires) Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road surface.

Therefore, pay attention to the following:

■If tire inflation pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined.

Tire rotation

Rotate the tires in the order shown.

To equalize tire wear and extend tire life, Lexus recommends that tire rotation is carried out at the same interval as tire inspection.

Do not fail to initialize the tire pressure warning system after tire rotation.

Lexus ES. Do-it-yourself maintenance

■When rotating the tires Make sure that the power switch is off. If the tires are rotated while the power switch is in ON mode, the tire position information will not be updated.

If this accidentally occurs, either turn the power switch to off and then to ON mode, or initialize the system after checking that the tire pressure is properly adjusted.

Tire pressure warning system

Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise.

The illustration used is intended as an example, and may differ from the image that is actually displayed on the multi-information display.

■Routine tire inflation pressure checks The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.

■Tire inflation pressure

■Situations in which the tire pressure warning system may not operate properly

If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.

■Warning performance of the tire pressure warning system The warning of the tire pressure warning system will change in accordance with driving conditions. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed.

When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized.

■When replacing the tires and wheels If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. After driving for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction.

Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized in the following circumstances:

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.

■ How to initialize the tire pressure warning system

1. Park the vehicle in a safe place and stop the hybrid system for 20 minutes or more.

Initialization cannot be performed while the vehicle is moving.

2. Adjust the tire inflation pressure to the specified cold tire inflation pressure level.

Make sure to adjust the tire pressure to the specified cold tire inflation pressure level.

The tire pressure warning system will operate based on this pressure level.

3. Start the hybrid system.

4. Press or of the meter control switches and select .

5. Press   or  of the meter control switches and select "Vehicle Settings", then press "OK".

6. Press or of the meter control switches and select "TPWS", then press "OK".

7. Press or of the meter control switches and select "Set Pressure".

Then press and hold "OK" until the tire pressure warning light starts blinking.

A message is displayed on the multi-information display. Also, "--" is displayed for inflation pressure of each tire on the multi-information display while the tire pressure warning system determines the position.

8. Drive at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.

When initialization is complete, the inflation pressure of each tire will be displayed on the multi-information display.

Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, initialization can be completed by driving for a long time. However, if initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

■If the tire pressure warning system is not initialized properly

If initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

If initialization cannot be completed after performing the above procedure, contact your Lexus dealer.

WARNING

■When initializing the tire pressure warning system Do not initialize tire inflation pressure without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure 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.

Registering ID codes

Every tire pressure warning valve and transmitter has a unique ID code.

When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code.

When registering the ID codes, perform the following procedure.

1. Park the vehicle in a safe place, wait for approximately 20 minutes, and then start the hybrid system.

2. Press or of the meter control switches and select .

3. Press or of the meter control switches and select "Vehicle Settings", and then press "OK".

4. Press or of the meter control switches and select "TPWS", and then press "OK".

5. Press or of the meter control switches and select "Change Wheel Set". Then press and hold "OK" until the tire pressure warning light starts slowly blinking 3 times.

Then a message will be displayed on the multi-information display.

When registration is being performed, the tire pressure warning light will blink for approximately 1 minute then illuminate and "--" will be displayed for the inflation pressure of each tire on the multi-information display.
