Checking the coolant

2706-3. Do-it-yourself maintenance
When the tire pressure warning system
is initialized, the current tire inflation
pressure is set as the benchmark pres-
sure.
■How to initialize the tire pressure
warning system
1 Park the vehicle in a safe place, turn
the engine switch off and wait 20
minutes or more.
Initialization cannot be performed while
the vehicle is moving.
2 Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level.
Make sure to adjust th e tire pressure to the
specified cold tire infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Start the engine. ( P.127)
4 Press and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks slowly
3 times.
Then a message will be displayed on the
multi-information display.
5Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
Initialization is complete when the position
of each tire is determined and the inflation pressure of each tire
is displayed on the
multi-information display.
■Initialization procedure
●Make sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initialization or tire inflation
pressure adjustment.
●If you have accidentally turned the engine
switch off during initialization, it is not
necessary to press the reset switch again
as initialization will restart automatically
when the engine switch has been turned
to IGNITION ON mode for the next
time.
●If you accidentally press the reset switch
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
■If the tire pressure warning system is not
initialized properly
●In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. (Usually,
the vehicle will need to be driven for
approximately 10 to 30 minutes to com-
plete initialization.) If initialization is not
complete after drivin g approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to complete ini-
tialization.
• If the vehicle is backed up while perform-
ing initialization, data collected during ini-
tialization will be cleared and it will take
longer than normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other vehicles
are driven close by, it may take time for
the system to recognize the tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles.
If initialization is not complete after driving
for approximately 1 hour, park the vehicle in
a safe place for approximately 20 minutes
and then drive the vehicle again.
●In the following situations, initialization
will not be started or was not completed
properly and the system will not operate

Maintenance and care
properly. Perform the initialization proce-
dure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes after performing ini-
tialization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
●If initialization cannot be completed after
performing the above procedure, con-
tact 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 necessary
to register the ID codes.
1 Park the vehicle in a safe place, turn
the engine switch off, wait 20 min-
utes or more, and then start the
engine.
2 Start the engine. ( P.127)
3 Press the tire pressure warning
reset switch 3 times quickly.
The tire pressure wa rning light will blink
slowly 3 times.
Sensor registration mode will be entered
and ID codes registration will begin. A message will be displayed on the
multi-information display and “- -” will be
displayed for the tire
inflation pressure of
each tire.
After this, the tire pr essure warning light
will blink for 1 minute and then illuminate.
4Wait approximately 2 minutes.
If the ID codes are already registered, the
tire pressure warning light will turn off.
If the tire pressure warning light
turns off
5 Initialize the tire pressure warning
system. ( P.269)
If the tire pressure warning light
does not turn off
5 Drive at approximately 25 mph
(40 km/h) or more until the tire
pressure warning light turns off.
6 Initialize the tire pressure warning
system. ( P.270)
■When registering ID codes
●Before performing ID code registration,
make sure that no wheels with tire pres-
sure warning valve and transmitters
installed are near the vehicle.
●Make sure to initializ e the tire pressure
warning system after registering the ID
codes. If the system is initialized before
registering the ID codes, the initialized
values will be invalid.
●As the tires will be warm when registra-
tion is completed, ma ke sure to allow the
tires to cool before performing initializa-
WARNING
■When initializing the tire pressure
warning system
Do not operate the ti re pressure warning
reset switch without first adjusting the tire
inflation pressure to the specified level.
Otherwise, the tire pressure warning
light may not come on even if the tire
inflation pressure is low, or it may come
on when the tire inflation pressure is
actually normal.
