5-2. Steps to take in an emergency
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on
the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)
●If tire chains are used.
■If the tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the engine switch is turned to the ON position, have it
checked by your Toyota dealer.
■ After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. ( P. 483)
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked front passenger’s seat belt reminder buzzer can be
disabled. (Customizable features P. 633)
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.

552 5-2. Steps to take in an emergency
CAUTION
■Maintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressu re telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire main tenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

5-2. Steps to take in an emergency
Stowing the flat tire, jack and all tools
Remove the center wheel ornament by pushing from thereverse side.
Lay down the tire with the outer side facing up, and install the
holding bracket.
Then secure the tire, taking care that the tire goes straight up
without catching on any other part, to prevent it from flying for-
ward during a collision or sudden braking.
Keep winding until three clicks are heard.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warning system must be reset. (P. 495)
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warn-
ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.
CAUTION
■Using the jack
Improper use of the jack may lead to death or injuries due to the vehicle
suddenly falling off the jack.
●Do not use the jack for any purpose other than replacing tires or install-
ing and removing tire chains.
●Only use the jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, an d do not use other jacks for replac-
ing tires on this vehicle.
●Always check that the jack is securely set to the jack point.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
