Tires
Installing tire inflation pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and the tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. ( →P. 303)
Replace tires in accordance with ma intenance schedules and tread wear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear indi-
cators is shown by the “TWI” or
“ ” marks, etc., molded on the
sidewall of each tire.
■The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise. ( →P. 358, 367)

Initializing the tire pressure warning system■ The tire pressure warning system must be initialized when the tire
inflation pressure is changed (such as when changing traveling
speed.)
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
To initialize the system, use the satellite switch. ( →P. 2 4 0 )
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch to OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (→ P. 4 1 1 )
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.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.

Registering and selecting ID codes
To select tire pressure warning valve and transmitter ID codes, use the
satellite switch. ( →P. 2 4 0 )
■ Registering ID codes
2 sets of tire pressure warning valve and transmitter ID codes can be
registered. Once a second set of tires is registered at “2ND”, you can
switch between tire set settings simply by pressing the “ON/OFF” but-
ton.
There are 2 settings:
“MAIN” position: The ID code of the tire pressure warning valve and
transmitter on the tires originally installed on the
vehicle is registered.
“2ND” position: The ID code is not registered. When you replace a new set of tires, purchase tire pressure warning
valves and transmitters from your Lexus dealer and
have the new ID code registered by your Lexus
dealer.

When replacing tires, make sure to select the ID code set that matches
the new tire set. If the ID code is set to the wrong tire setting, the tire
pressure warning system will not operate properly. After driving for
about 20 minutes, the tire pressure warning light comes on after blink-
ing for 1 minute to indicate a system malfunction.

■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing 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 comes on after blinking for 1 minute to indi-
cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been us ed or damage is not obvious.
■If the tread wears down below 0. 16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Tire rotation
It is not possible to rotate the tires, as each tire and wheel is designed only for its
original position on the vehicle.
■Tire replacement
→ P. 3 1 6
■Low profile 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.
