■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (P. 400)
●If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this vehicle. Because certain bulbs are connected to circuits designed to prevent over- load, non-genuine parts or parts not designed for this vehicle may be unus- able.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions. Failure to do so may cause damage to the vehicle, and possibly a fire or injury. ●Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
●Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
●Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.

■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●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 pressure warning system may not work properly with some types of tires.)

5-2. Steps to take in an emergency
CAUTION
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy. If the steering wheel becomes heavier than usual when operating, hold firmly and operate using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a 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 infla-
tion pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If the tire is flat, temporarily repair it with liquid sealants and have the flat tire repaired or replaced by the nearest Toyota dealer as soon as possible.
●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 system may not activate immediately.
424
5-2. Steps to take in an emergency
CAUTION
■Maintenance of the tires
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 pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS-tire pressure warning system) that illuminates a low tire pressure telltale (tire pressure warning light) when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure 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 efficiency (for electric vehicles, traction battery efficiency) and tire tread life, and may affect the vehicle's han- dling and stopping ability. Please note that the TPMS (tire pressure warning system) is not a sub- stitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale (tire pressure warning light).
425
5-2. Steps to take in an emergency
CAUTION
Your vehicle has also been equipped with a TPMS (tire pressure warning system) malfunction indicator to indicate 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 detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illumi- nated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illumi- nated, the system may not be able to detect or signal low tire pressure as intended. TPMS (tire pressure warning system) malfunctions may occur for a vari- ety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS (tire pressure warning system) from functioning properly. Always check the TPMS (tire pres- sure warning system) malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alter- nate tires and wheels allow the TPMS (tire pressure warning system) to continue to function properly.
NOTICE
■Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres- sure warning system may not operate properly.
