STARTING AND DRIVING
Selector switch
31sa21a
" 1 Main position
2 2nd position
The selector switch is located on the right side in the glove
box.
The ID code is given in the sender built in the air pressure
sensor. To activate the air pressure warning system, it is
necessary to register the ID code of the sender 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 air 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.

CAUTION
When the tires whose ID code is registered at "MAIN"
are used, the system does not work properly with the
selector switch set at "2nd". If the tires whose ID code
is registered at "2nd" are stored nearby, the system will
detect their tire pressure (and vice versa).
Liquid sealants for flat tires
NOTICE
Do not use liquid sealants for flat tires as the air
pressure sensors will be damaged.
