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 such as nearby public phones.
• It may sometimes be difficult to connect to the public Safety Answering Point (PSAP) even in the reception area of the 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 w ill 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 th e “SOS” button panel, indicator lights,
microphone, speaker, DCM, antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency Call cannot be made.• During the Emergency Call, the system makes repeated attempts to connect to
the Public Safety Answering 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 cellular network and the call may finish with-
out connecting. The red indicator light w ill blink for approximately 30 seconds to indicate this disconnection.• This device may not function if a shock is applied to it.
●If the 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. Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refillin g, it may indicate a serious problem.
