● ID code registration is performed while
driving at a vehicle speed of approxi-
mately 25 mph (40 km/h) or more.
● ID codes can be registered by yourself,
but depending on the driving conditions
and driving environment, registration
may take some time to complete.
● When using a wheel set which all of the
ID codes have already been registered,
the wheel set can be changed in a short
amount of time. (P.585)
■ If ID codes are not registered easily
● In the following situations, ID code regis-
tration may take longer than usual to be
completed or may not be possible.
• When the vehicle has not been parked
for approximately 15 minutes or more
before being driven
• Vehicle is not driven at approximately 25
mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles and
system cannot recognize tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles
• Wheel with tire pressure warning valve
and transmitter installed is inside or near
the vehicle
● If the vehicle is reversed during registra-
tion, all data collected until then will be
cleared. Perform driving again.
● If registration does not complete after
driving for 1 hour or more, perform the ID
code registration procedure again from
the beginning.
● If the tire pressure warning light does not
blink 3 times when starting ID code reg-
istration procedure, the procedure may
not have started. Perform the procedure
again from the beginning.
● If the ID codes cannot be registered even
when performing the above procedure,
contact your Lexus dealer.
To cancel ID code registration after it
has been started, select “New tire reg-
istration” again on the multimedia dis-
play.
If ID code registration has been canceled,
the tire pressure warning light will turn off.
If the warning light does not turn off, ID
code registration may not have been can-
celled correctly. To cancel registration,
select “New tire registration” again on the
multimedia display.
Your vehicle is equipped with a tire
pressure warning system with a func-
tion to register two sets of ID codes.
This allows for registration of a second
wheel set, for example a winter set.
The wheel set can be changed only
if a second wheel set has been reg-
istered to the system. If a second
wheel set has not been registered,
“Set 2 (Unregistered)” will be dis-
played and it will not be possible to
change to the selected wheel set.
ID codes can be registered by yourself.
(P.583)
Only a change between both regis-
tered wheel set is possible, mixing
between these wheel sets is not sup-
ported.
While registering ID codes, it may
not be possible to change between
wheel sets normally. Cancel regis-
tration before changing between
wheel sets.
