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. 635)
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
overload, nongenuine parts or parts not designed for this vehicle may be
unusable.
WARNING
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.

5-4. Using the other interior features
WARNING
If you smell anything burning or another unusual smell, do not stay inside
the vehicle and evacuate to a safe area immediately.
Since the system detects shocks, the automatic reporting may not always
occur synchronized with the operation of the airbag system. (If the vehicle
is bumped from behind, etc.)
The airbag may not inflate even in case of an accident, if it does not
involve high impact. In such cases, the system may not make emergency
calls automatically. The system may also not make automatic emergency
calls even if the airbag has been inflated. If any of these should occur,
please report to the Public Safety Answering Point (PSAP) by operating
the “SOS” button.
For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of the steering wheel,
which may lead to unexpected accidents.
Stop the vehicle and confirm the safety of the area before making the
Emergency Call.
When changing fuses, please use fuses that correspond to the described
standard. If you use fuses other than those described, it may cause igni-
tion or smoke in the circuit and may lead to a fire.
Using the system while there is smoke or an unusual smell may cause a
fire. Stop using the system immediately and consult any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
NOTICE
To prevent damage
Do not pour any liquid on to the “SOS” button panel etc. and make any
impact to it.
If the “SOS” button panel malfunctions
It may not be able to make the Emergency Call or inform you of the correct
condition of the system. If the “SOS” button panel has been broken, please
consult any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
If there is any malfunction of the speaker or the microphone during the
Emergency Call or the Manual Maintenance Check
You will not be able to communicate with the Public Safety Answering Point
(PSAP) operator.
If any of this equipment has been broken, please consult any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
