Toyota Corolla Cross: Tire pressure warning
system
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect low tire inflation pressure before
serious problems arise.
The tire pressure warning system
of this vehicle adopts a
2-type warning system.
- When "Adjust Pressure" is
displayed (Normal Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low due to natural air
leakage or outside temperature.
- When "Immediately Check
tire when Safe" is displayed
(Emergency Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout.
However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-information
display.
The unit can be changed.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks. Make sure to
check tire inflation pressure as part
of your routine of daily vehicle
checks.

■Situations in which the tire
pressure warning system may
not operate properly
- In the following cases, the tire pressure warning system may not
operate properly.
- If non-genuine Toyota wheels are
used.
- A tire has been replaced with a
tire that is not an OE (Original
Equipment) tire.
- A tire has been replaced with a
tire that is not of the specified size.
- Tire chains, etc. are equipped.
- An auxiliary-supported run-flat tire
is equipped.
- If a window tint that affects the
radio wave signals is installed.
- If there is a lot of snow or ice on
the vehicle, particularly around the
wheels or wheel housings.
- If the tire inflation pressure is
extremely higher than the specified
level.
- If wheel without tire pressure
warning valves and transmitters
are used.
- If the ID code on the tire pressure
warning valves and transmitters is
not registered in the tire pressure
warning computer.
- Performance may be affected in
the following situations.
- Near a TV tower, electric power
plant, gas station, radio station,
large display, airport or other facility
that generates strong radio
waves or electrical noise
- When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
- If tire position information is not
correctly displayed due to the
radio wave conditions, the display
may be corrected by driving and
changing the radio wave conditions.
- When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
- When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.
READ NEXT:
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
regist
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID
Your vehicle is equipped with
tire pressure warning system
with the function to have ID
codes registered for a second
wheel set, for example a winter
set. You can register a second
wheel set by yourse
