REPLACING WHEELS
As you might have difficulty in identifying a flat or deflated
tire, a tire pressure warning system is provided on this
vehicle.
When replacing the wheels, be sure to install tire pressure
sensors on the wheels.
There are 2 ways to set up the tire pressure sensors.
a. Remove the sensor from the old wheel and install it to the
new wheel.
b. 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
purchased later, put the switch at “2nd”. For the sensor
selector switch, see page 442.
CAUTION
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 sensor to transmit the electronic code in
different manner, resulting in the failure of the
system.
When to replace your wheels
If you have wheel damage such as bending, cracks or
heavy corrosion, the wheel should be replaced.
If you fail to replace a damaged wheel, the tire may slip off the
wheel or cause loss of handling control.
Replacement with used wheels is not recommended as they
may have been subjected to rough treatment or high mileage
and could fail without warning. Also, bent wheels which have
been straightened may have hidden structural damage and
therefore should not be used. Never use an inner tube in a
leaking wheel which is designed for a tubeless tire.
