■Indicators
The indicators inform the driver of th e operating state of the vehicle’s
various systems.
*1: These lights turn on when the ignition switch is turned to the “ON” position to indicate that a system check is being performed. They will turn off after the
engine is started, or after a few seconds. There may be a malfunction in a sys-
tem if a light does not come on, or if th e lights do not turn off. Have the vehi-
cle inspected by your Lexus dealer.

Safety Connect LED light IndicatorsWhen the ignition switch is turned to the “ON” position, the red indicator
light comes on for 2 seconds then tu rns off. Afterward, the green indica-
tor light comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage con-
ditions:
● Green indicator light on = Active service
● Green indicator light flashing = Safety Connect call in process
● Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
● No indicator light (off) = Saf ety Connect service not active
Safety Connect services
■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to asse ss 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, and requests that assistance be sent
to the location.

Maintenance and care
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(  P. 6 3 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.
■Cleaning the leather areas of the instrument panel
Do not use any protective agents (coating s etc). Doing so may cause the instrument
panel to reflect onto the windshield, obstructing the front view and possibly causing
an accident.

When trouble arises

5-1. Essential information
Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or when an airbag
inflates upon collision, the fuel pump shut off system stops the supply of fuel to
the engine.
Follow the procedure below to restart the engine after the system is acti-
vated.
Turn the ignition switch to the “ACC” or “LOCK” position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.

5-1. Essential information
Event data recorder
This vehicle is equipped with an event data recorder (EDR). The main purpose
of an EDR is to record, in certain crash or near crash-like situations, such as an
airbag deployment or hitting a road obstacle, data that will assist in under-
standing how a vehicle's systems perf ormed. The EDR is designed to record
data related to vehicle dynamics and safe ty systems for a short period of time,
typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
● How various systems in your vehicle were operating;
● Whether or not the driver and passenger safety belts (seat belts) were
buckled/fastened;
● How far (if at all) th e driver was depressing the accelerator and/or
brake pedal; and,
● How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances
in which crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicl e only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving condi-
tions and no personal data (e.g., na me, gender, age, and crash location)
are recorded. However, other parties, such as law enforcement, could
combine the EDR data with the type of personally identifying data rou-
tinely acquired during a crash investigation.
