system is designed to automatically call the response center. The
responding agent receives the vehicle’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the
occupants are unable to communicate, the agent automatically treats
the call as an emergency, contacts the nearest emergency services
provider to describe the situation, an d requests that assistance be sent
to the location.

■Repair and replacement
It is recommended that genuine Lexus parts be used for repair to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair
shop other than a Lexus dealer performs repairs, confirm the warranty coverage.
To ensure safe and economical driving, day-to-day care and regular main-
tenance are essential. It is the owner’s responsibility to perform regular
checks. Lexus recommends performing the following maintenance:
■General maintenance
General maintenance should be performed on a daily basis. This
can be done by yourself or by a Lexus dealer.
■ Scheduled maintenance
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For details about maintenance items and schedules, refer to the “War-
ranty and Service Guide”, “Owner’s Manual Supplement” or “Scheduled
Maintenance”.
■Do-it-yourself maintenance
You can perform some maintenance procedures by yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Lexus repair manuals is recommended.
For details about warranty coverage, refer to the separate “Owner’s
Guide”, “Warranty and Service Guide”, “Owner’s Manual Supplement”
or “Warranty Booklet”.
