FCC WARNING:
Changes or modifications not expressly approved
by the party responsible for compliance could void
the user’s authority to operate the equipment.
For vehicles sold in Canada
Operation is subject to the following two conditions: (1)
this device may not cause interference, and (2) this
device must accept any interference, including
interference that may cause undesired operation of the
device.
Replacing tires and wheels
As you might have difficulty in locating a flat or deflated
tire, a tire pressure warning system should be installed on
the tires of this vehicle.
When replacing the wheels, be sure to install tire pressure
sensors on the wheels.
There are 3 ways to set up the tire pressure sensors:
a. Remove the sensor from the old wheel and install it to the
new wheel.
b. Keep the same wheel with tire pressure sensor and replace
the tire alone.
c. Use a new wheel and sensor.
You have to register an ID code for a new sensor. Up to 2
sets of codes can be registered. As one ID for the originally
installed sensor is registered at “MAIN” of the selector
switch, use the “2nd” position to register an ID for the new
sensor.
You do not need to re−register the ID code for any other
replacements. For the use of the originally installed tires,
put the selector switch at “MAIN” and for the use of tires set
purchased later, put the switch at “2nd”. For the sensor
selector switch, see page 442.

NOTICE
Have the tires, wheels or sensors replaced and ID
codes registered by Lexus dealer. If you need
sensors, purchase from Lexus dealer.
The sensor nuts should always be tightened to a
torque of 4 N·m (0.4 kgf·m, 2.9 ft·lbf).
The use of non−genuine wheels will cause the tire
pressure sensors to transmit the electronic code in
different manner, resulting in the failure of the
system.
Tire pressure warning system reset switch
G31004
The tire pressure warning system needs to be initialized
in the following conditions:
After replacing or rotating tires or wheels
After replacing the tire pressure sensor
When initializing the system, the present tire condition is
stored as a standard.

STARTING AND DRIVING
441 To initialize the system, perform the following:
1. Park the vehicle at a safe place and apply the parking brake.
Stop the engine.
2. Adjust the pressure of all the installed tires to the specified
level. (See “Tires and wheels” on pages 534 and 537.)
3. Start the engine.
4. Push and hold the reset switch until the low tire pressure
warning light blinks three times, and the message
“PRESSURE INITIAL” appears on the multi−information
display.
Do not turn the engine off for about 20 minutes until
initialization is complete.
G31007
When initializing the system, make sure the low tire pressure
warning light blinks three times and the message “PRESSURE
INITIAL” appears on the multi−information display. If the
warning light does not blink three times and the message does
not appear on the multi−information display, initialization failed
and the tire pressure warning system will not function properly.
In this case, initialize the system again.
Do not push the reset switch without adjusting the tire inflation
pressure to the specified level. Otherwise, the low 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.
If you push the reset switch while the vehicle is moving,
initialization is not performed.
If the low tire pressure warning light does not blink and the
message does not appear on the multi−information display
when you push and hold the reset switch, have the tire
pressure warning system checked at your Lexus dealer.

NOTICE
Do not turn the engine switch off during initialization,
or the system may not function properly due to
incomplete initialization.
Check which tires are being used before initialization
of the system, and also check the selector switch
position. (See the following “Selector switch”.)
Selector switch
G31005

1
Main position 2
2nd position
The selector switch is located on the underside of the
glove box.
The ID code is given in the tire pressure sensor. To
activate the tire pressure warning system, it is necessary
to register the ID code of the sensor on the selector switch
in the vehicle.
2 sets of ID codes can be registered. The code of the tires
originally installed on the vehicle is registered on the switch at
“MAIN”. Have a new tires set with new tire pressure sensors
registered at “2nd” by Lexus dealer.
ID codes should be registered by Lexus dealer. Once
registered, change the setting position each time you purchase
tires and wheels. Re−registration is not required.
When purchasing new tires, consult your Lexus dealer.
