Directional tires
Tire direction marks
The tire sidewalls are marked with
arrows indicating the rolling direc-
tion of the tire. If mounted on the
wrong side of the vehicle, direc-
tional tires will not perform prop-
erly.
Installing tire 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 tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (

Initializing the tire pressure warning system
■
The tire pressure warning system must be initialized in the following
circumstances:
●
When changing the tire inflation pressure by changing traveling
speed or load weight, etc.
●
When changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.
