Maintenance and care
4RUNNER (U)■
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 the “LOCK” position
(vehicles without a smart key system) or off (vehicles with a s mart key
system) during initialization, it is not necessary to press the reset switch
again as initialization will rest art automatically when the engine switch
has been turned to the “ON” posi tion (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicl es with a smart key system) 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.
■When initialization of the tire pressure warning system has fai led
●Do not move the vehicle backward during initialization. Initialization is
started again from the beginning and it may take longer than usual.
●Initialization may take longer to complete if the vehicle is driven on an
unpaved road.
When performing initialization, drive on a paved road if possib le.
Depending on the driving environment and condition of the tires , initial-
ization will be complet ed in approximately 10 to 30 minutes.
• If initialization is not complet e after driving approximately 30 minutes,
continue driving for a while.
• If initialization is not complet e after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left a nd right turns) at approximatel y 25 mph
(40 km/h) or more
* for approximately 10 to 30 minutes.
• If initialization is still not co mplete, have the vehicle inspected by your
Toyota dealer.
*: Except when making a left/right turn
●In the following situations, the tire inflation pressure will n ot be recorded
and the system will not operate p roperly. Perform initialization again.
• When operating the tire pressure warning reset switch, the tir e pres-
sure warning light does not blink 3 times.
• After performing initialization, the tire pressure warning light blinks for
1 minute then stays on after driving for about 20 minutes.

When ID code registration has failed
●Registration may take long time or the ID codes may not be regi
stered in
the following situations.
• When the vehicle is moved backward during registration.
Registration is started again from the beginning and it may tak e lon-
ger than usual.
• When another vehicle is running the side of the vehicle such a s in
heavy traffic.
It may take longer to detect the vehicle’ tire pressure warning valves
and transmitters.
• If tire pressure warning valves and transmitters are in the vehicle.
The ID codes may n ot be registered.
●When performing registration, drive on a paved road if possible .
Depending on the driving environment and condition of the tires, regis-
tration will be complet ed in approximately 10 to 30 minutes.
• If registration is not complete after driving approximately 30 minutes,
continue driving for a while.
• If registration is not complete after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left and right turns) at approximatel y 40 km/h
(25 mph) or more
* for approximately 10 to 30 minutes.
If registration is still not comp lete, have the vehicle inspected by your
Toyota dealer.
*: Except when making a left/right turn
●When the tire pressure warning light does not blink slowly 3 ti mes, the
ID code will not be registered and the system will not operate properly.
Perform registration again.
■When registering ID codes
●Initialize the tire pressure war ning system after ID code regis tration. Ini-
tialization is disable d if the system was initialized before re gistration.
●After ID code registration, the tires are hot by driving. Initi alize the tire
pressure warning system af ter the tires become cold.
■Canceling the change wheel set mode
●If turning the engine switch to the “LOCK” position (vehicles w ithout a
smart key system) or off (vehicles with a smart key system) whe n in the
change wheel set mode before driving, the change wheel set mode is
canceled.
●After driving when in the change wheel set mode, the change whe el set
mode cannot be canceled. To cancel the mode, perform the proced ure
for ID code registration again and turn the engine switch to th e “LOCK”
position (vehicles without a smart key system) or off (vehicles with a
smart key system ) before driving.
