◆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 inflation pressure is changed such as when chang-
ing tire size. (When there are multiple specified pressures)
● After registeri ng the ID codes. ( P. 429)
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in s afe place and turn the engine switch off.
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 529)
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 ON.
Push and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks 3 times.
A message is displayed on the
multi-information display. Also,
“- -” is displayed for inflation
pressure of each tire on the
multi-information display while
the tire pressure warning sys-
tem determines the position.

The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to OFF during initial-
ization, it is not necessary to press the reset switch again as initialization
will restart automatically when the engine switch has been turned to ON
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 i n approximately 10 to 30 minutes. If initial-
ization is not complete after dr iving approximately 10 to 30 mi nutes, con-
tinue driving for a while.
If the inflation pressure of each tire is not displayed after d riving for
approximately 1 hour, perf orm 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 approximately 10 to 30 minutes.
However, in the following situatio ns, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After performing initialization, t he tire pressure warning light blinks for
1 minute then stays on while driving about 20 minutes.
If the inflation pressure of eac h tire is still not displayed, have the vehicle
inspected by you r Toyota dealer.
