3626-3. Do-it-yourself maintenance
Make sure to adjust the 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 Turn the engine switch to IGNI-
TION ON mode.
4 Select on the multi-information
display.
5 Press or of the meter con-
trol switch, select the “Vehicle Set-
tings” screen and then press the
.
6 Press or of the meter con-
trol switch, select the “TPMS”
screen and then press and hold the
until the tire pressure warn-
ing light blinks slowly 3 times.
“- -” will be displayed for inflation pressure
of each tire on the multi-information dis-
play while the tire pressure warning system
determines the position of each tire.
7 Drive the vehicle at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes
until the inflation pressure of each
tire is displayed on the multi-infor-
mation display.
When position of each tire is determined,
the inflation pressure of each tire will be
displayed on the multi-information display.
If tire inflation pr essure becomes low before the inflation pressure is displayed,
the tire pressure warning light will come
on.
Depending on the vehicle and driving con-
ditions, initialization may take up to
approximately 1 hour to complete.
■Initializing the tire pressure warning sys-
tem
Initialize the system with the tire inflation
pressure adjusted to the specified level.
■If you press the tire pressure warning
reset switch accidentally
If initialization is perf ormed, adjust the tire
inflation pressure to the specified level and
initialize the tire pres sure warning system
again.
■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.
●While the position of each tire is being
determined and the inflation pressures
are not being displayed on the
multi-information display, if the inflation
pressure of a tire drops, the tire pressure
warning light will come on.
■When initialization of the tire pressure
warning system has failed
Initialization may take longer to complete if
the vehicle is driven on an unpaved road.
When performing initialization, drive on a
paved road if possible. Depending on the

may sound.
■When the tire pressure warning light
comes on
Inspect the tires to check if a tire is punc-
tured.
If a tire is punctured: P.406
If none of the tires are punctured:
Turn the engine switch off then turn it to
IGNITION ON mode. Check if the tire
pressure warning light comes on or blinks.
If the tire pressure wa rning light blinks for
1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle
inspected by your Lexus dealer immedi-
ately.
If the tire pressure warning light comes
on
1 After the temperature of the tires has
lowered sufficiently, check the inflation
pressure of each tire and adjust them to
the specified level.
2 If the warning light does not turn off
even after several minutes have
elapsed, check that the inflation pres-
sure of each tire is at the specified level
and perform initialization. ( P.361)
If the warning light does not turn off several
minutes after the initia lization has been per-
formed, have the vehicle inspected by your
Lexus dealer immediately.
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come
on due to natural causes such as natural air
leaks and tire inflation pressure changes
caused by temperature. In this case, adjust-ing the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with
a tire pressure warning valve and transmit-
ter. If a tire goes flat , the tire pressure warn-
ing light will not turn off even though the flat
tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire
and adjust the tire inflation pressure. The
tire pressure warning light will go off after a
few minutes.
