Replacing tires and wheels
When replacing the tires and wheels, be sure to install tire
pressure warning valves and transmitters. ID codes on the tire
pressure warning valves and transmitters are registered on the
tire pressure warning ECU. When replacing a tire pressure
warning valve and transmitter, it is necessar y to register the ID
code of tire pressure warning valve and transmitter. Have the
ID code registered by your Lexus dealer.
If the ID code is not registered, the system will not work
properly. After about 1 hour, the tire pressure warning light
blinks to indicate a system malfunction.
NOTICE
When the tires or tire pressure warning valves and
transmitters must be replaced, have them replaced by
your Lexus dealer. The tire pressure warning valves
and transmitters will be affected by the installation or
removal of tires.
Tire pressure warning reset switch
G31004a
When initializing the system, the present tire inflation pressure
is stored as standard. The tire pressure warning system
determines decreased air pressure by comparing the present
and the standard tire inflation pressures. When you change
the set tire inflation pressure, it is necessary to initialize the tire
pressure warning system.
When rotating the tires on vehicles differing with front and
rear tire inflation pressures.
When changing the tire inflation pressure by changing
traveling speed or load weight, etc.
When changing the tire size.

STARTING AND DRIVING
447
To initialize the system, perform the following:
1. Park
the vehicle in a safe place and select the engine switch
in “OFF” mode.
2. Adjust the pressure of all the installed tires to the specified
cold tire inflation pressure level. (See “Tire and wheels” on
pages 542 and 546.)
3. Select the engine switch in “IG −ON” mode.
4. Push and hold the tire pressure warning reset switch until
the tire pressure warning light blinks slowly three times and the
message “PRESSURE INITIAL” appears on the
multi−information display.
5. Wait for a few minutes with the engine switch in “IG −ON”
mode, and then select the engine switch in “OFF” position.
If you push the tire pressure reset switch while the vehicle is
moving, initialization is not performed.
If you push the tire pressure reset switch accidentally and
initialization is performed, adjust the tire inflation pressure to
the specified level and initialize the system again.
G31007
If the tire pressure warning light does not blink slowly three
times and the message “PRESSURE INITIAL” does not
appear on the multi −information display when you push and
hold the reset switch, initialization has failed and the tire
pressure warning system may not work properly. In this case,
initialize the system again. If initialization cannot be
performed, have the system checked at your Lexus dealer.

CAUTION
Do not push the reset switch 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.
Tire pressure warning select switch
G31005a
1 Main position 22nd position
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 tire pressure
warning select switch.
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 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.

If the tire pressure select switch is set to the wrong tire setting,
the system will not work properly. After about 1 hour, the tire
pressure
warning light blinks to indicate a system malfunction.
PRE COLLISION SYSTEM
(Vehicles with dynamic radar cruise control)
When the pre collision system detects what it perceives
to be an unavoidable collision, the front seat belts are
quickly drawn back by the retractors (pre collision seat
belts) and more powerful braking is applied according to
the amount of pedal depression to help reduce injury to
the occupants and damage to the vehicle body. In
addition, the adaptive variable suspension works to help
regulate the vehicle not to pitch forward so much.
The pre−collision system will operate when the engine switch
is selected in “IG −ON” mode.
