■For your safety
●Please drive safely.
The function of this system is to assist you in making the Emergency Call in case of

belts at all times for your safety.
●In case of an emergency, make lives the top priority.
●If you smell anything burning or another unusual smell, do not stay inside the vehicle

●Since the system dete cts shocks, the automatic reporting may not always occur syn- chronized with the operation of the airbag system. (If the vehicle is bumped from

●The airbag may not inflate even in case of an accident, if it does not involve high impact. In such cases, the system may no t make emergency calls automatically. The
system may also not make automatic emer gency 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 mish andling 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 th at correspond to the described standard. If
you use fuses other than those described, it may cause ignition or smoke in the circuit

■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. 556)
●If the replaced fuse blows again, have the vehicle inspected by any authorized Lexus
retailer or Lexus authorized re pairer, or any reliable repairer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this vehicle. Because certain bulbs are connected to circui ts designed to prevent overload, non-gen-
uine 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 th e 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 Lexus fuse or equivalent.
Never replace a fuse with a wi re, even as a temporary fix.
●Do not modify the fuses or fuse boxes.
■Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring near the fuse box.
Doing so may cause electric shock, re sulting in death or serious injury.
NOTICE
■Before replacing fuses
Have the cause of electrical overload de termined and repaired by any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible.
