NOTICE
When the snow tires must be repaired or replaced,
have them repaired or replaced by Lexus dealer or
authorized tire dealer. The tire pressure sensor will
be affected by the installation or removal of snow
tires.
When the snow tires must be replaced, replace the
grommets for air pressure sensors as well.
Do not attempt to use a tire chain on the compact
spare tire, as it may result in damage to the vehicle as
well as the tire.
INFORMATION
If the chains are installed, the air pressure warning
system may not operate properly.
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer’s recommended speed limit,
whichever is lower.
Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
Avoid sharp turns or locked–wheel braking, as use of
chains may adversely affect vehicle handling.
When driving with chains installed, be sure to drive
carefully. Slow down before entering curves to avoid
losing control of the vehicle. Otherwise an accident
may occur.
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 air pressure
sensors on the wheels.
There are 2 ways to set up the air 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 224.
