6-3. Do-it-yourself maintenance
Your Toyota is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
● If the tire pressure drops below a predetermined level, the dri ver is
warned by a screen display and a warning light. ( P. 5 2 3 )
● The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
◆Installing tire pressure warn ing valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter I D
codes registered by your Toyota dealer.
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires.
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the pressure benchmark.

Maintenance and care
■How to initialize the tire pressure warning systemPark the vehicle in s afe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moved.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 570)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Turn the engine switch to IGNITION ON mode.
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
“--” will be displayed for inflat ion pressure of each tire on t he multi-
information display while the ti re pressure warning system deter-
mines the position on the m ulti-information display.
When position of each tire is determined, the inflation pressur e of
each tire will be displayed on the multi-information display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
When initialization is complete, the inflation pressure of each tire will
be displayed on the multi-information display.
Depending on the vehicle and drivi ng conditions, initialization may
take up to appro ximately 1 hour to complete.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped wit h a
unique ID code. When replacing a tire pressure warning valve an d
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.

■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for 1
minute and stays on to indi cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.1 0 of the
replacement tire is greater than 1/2 of the Gross Axle Weight R atings
(GAWR) of either the front axle or the rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. ( P. 5 7 5 )

Maintenance and care
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure. 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 in itialization,
it is not necessary to press the reset swit ch again as initialization will
restart automatically when the engine switch has been turned to IGNI-
TION ON mode for the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and cond uct initialization again.
●While the position of each tire is being determined and the inf lation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with the conditions under which it was initialized. For t his reason,
the system may give a warning even if the tire pressure does no t reach a
low enough level, or if the pressure is higher than the pressur e that was
adjusted to when the sys tem was initialized.
■When initialization of the tire pressure warning system has fai led
Initialization may take longer to complete if the vehicle is driven on an
unpaved road. When performing ini tialization, drive on a paved road if
possible. Depending on the driving environment and condition of the tires,
initialization will be completed in approximately 10 minutes. If initialization
is not complete after driving app roximately 10 minutes, continue driving
for a while.
If the inflation of each tire is not displayed after driving fo r approximately 1
hour, perform the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then
drive straight (with occasional left and right turns) at approx imately
25 mph (40 km/h) or more for app roximately 10 to 20 minutes.
However, in the following situatio ns, the tire inflation pressure will not be
recorder and the system will not operate properly. Perform initialization.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After performing initi alization, the tire pressure warning ligh t blinks for 1
minute then stays on after driving for about 20 minutes.
If the inflation pressure of eac h tire is still not displayed, have the vehicle
inspected by you r Toyota dealer.
