Tire Pressure Warning
G13025
When the low tire inflation pressure is detected while
driving, the low tire pressure warning light and master
warning light come on, and the above message appears.
If the above message appears, adjust the tire inflation pressure
to the specified level as soon as possible. Push the tire
pressure warning system reset switch for a few seconds and
make sure the warning message goes off. If the message still
remains on, have your vehicle checked by your Lexus dealer
as soon as possible.
G13024
This message indicates the tire pressure warning system is
initialized. After replacing the tires or wheels, adjust all 4 tires
to specified tire inflation pressure and initialize the tire pressure
warning system. To initialize the system, start the engine and
push the tire pressure warning system reset switch for longer
than 3 seconds with the vehicle stopped. The above message
appears.
G13026
If there is a problem electrically in the tire pressure
warning system, the low tire pressure warning light and
master warning light blink and the above message
appears.
Although it is no problem to continue driving with the above
message on the display, have your vehicle checked by your
Lexus dealer as soon as possible.

STARTING AND DRIVING
440
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 nongenuine 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.
