QRepair and replacement
It is recommended that genuine Lexus parts
be used for repairs to ensure performance
of each system. If non-Lexus parts are used
in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm
the warranty coverage.
QAllow inspection and repairs to be per-
formed by a Lexus dealer

cialists and are kept up to date with the
latest service information. They are well
informed about the operations of all sys-
tems on your vehicle.
OKeep a copy of the repair order. It proves
that the maintenance that has been per-
formed is under warranty coverage. If
any problem should arise while your vehi-
cle is under warranty, your Lexus dealer
will promptly take care of it.
General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.

ule.

schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

3366-3. Do-it-yourself maintenance
OIf you accidentally perform initialization
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
OWhile the position of each tire is being
determined and the inflation pressures
are not being displayed on the multi-
information display, if the inflation pres-
sure of a tire drops, the tire pressure
warning light will come on.
QIf the tire pressure warning system is not
initialized properly
OIn the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Normally,
initialization completes within approxi-
mately 30 minutes.
• 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
If initialization does not complete after driv-
ing for 1 hour or more, park the vehicle in a
safe place for approximately 20 minutes
and then drive the vehicle again.
OIf the vehicle is reversed during initializa-
tion, the data up to that point is reset, so
perform the initia lization procedure
again from the beginning.
OIn the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization pro-

the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes afte r performing initial-
ization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
If initialization cannot be completed after
performing the above procedure, contact
your Lexus dealer.
Every tire pressure warning valve and
transmitter has a unique ID code.
When replacing a tire pressure warn-
ing valve and transmitter, it is neces-
sary to register the ID code.
When registering the ID codes, per-
