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 will 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 retailer or
Lexus authorized repairer, or any reliable repairer.

Maintenance and care
IS200t_EE(OM53D77E)7-2. Maintenance
Scheduled maintenance should be performed at specified intervals according to
the maintenance schedule.
For details about maintenance items and sche
dules, refer to the “Lexus Service Book-
let” or “Lexus Warranty Booklet”.
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance task s require special tools and skills. These
are best performed by qualified technicians. Even if you’re an experienced do-it-your-
self mechanic, we recommend that repairs and maintenance be conducted by any
authorized Lexus retailer or Lexus authoriz ed repairer, or any reliable repairer. Any
authorized Lexus retailer or repairer will keep a record of maintenance, which could
be useful should you ever require Warranty Service. Should you choose to select a
qualified and equipped professional other than an authorized Lexus repairer to ser-
vice or maintain your vehicle, we recommend that you request that a record of main-
tenance be kept.
Maintenance requirements
To ensure safe and economical drivin g, day-to-day care and regular mainte-
nance are essential. Lexus recommends the following maintenance:
