WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not automatically drive
the vehicle or reduce the amount of attention that must be paid to the area in front of
the vehicle. The driver must always assume full responsibility for driving safely by pay- ing careful attention to the surrounding cond itions and operating the steering wheel to
correct the path of the vehicle. Also, th e driver must take adequate breaks when
fatigued, such as from driving for a long period of time. Failure to perform appropriate driving operat ions and pay careful attention may lead to
an accident, resulting in death or serious injury.
■To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.

serious injury.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively worn, or when the tire inflation pressure is low.
●Tires which differ by structure, manufacturer, brand or tread pattern are used.
●Objects or patterns that could be mistaken for white (yellow) lines are present on the side of the road (guardrails, cu rbs, reflective poles, etc.).

WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety Answering
Point (PSAP) by other means su ch as nearby public phones.
• It may sometimes be difficult to connect to the public Safety Answering Point (PSAP) even in the reception area of t he cellular phone due to the reception level,
or if the line is busy. In such cases, you may not be able to connect to the Public
Safety Answering Point (PSAP) and thus will not be able to make emergency calls and report to the emergency departments even though the system tries to con-
nect to the Public Safety Answering Point (PSAP).
• When the vehicle is out of the cellular phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights,
microphone, speaker, DCM, antenna, or any wires connecting the equipment.) has an abnormality, is damaged or brok en, the Emergency Call cannot be made.
• During the Emergency Call, the system makes repeated attempts to connect to
the Public Safety Answerin g Point (PSAP). However, if it cannot connect to the Public Safety Answering Point (PSAP) due to poor radio wave reception, the sys-
tem may not be able to connect to the ce llular network and the call may finish with-
out connecting. The red indi cator light will blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.
●If the 12-volt battery’s voltage decreases or there is a disconnection, the system may
not be able to access the Public Safety Answering Point (PSAP).
■When replacing DCM to a new one
ERA-GLONASS have to be activated. Contac t any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.

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.

■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.
