For safety and security
●Safety Connect is available beginning Fall
2009 on select Lexus models (in the
contiguous United States only). Contact
with the Safety Connect response center
is dependent upon the telematics device
being in operative condition, cellular con-
nection availability, and GPS satellite sig-
nal reception, which ca n limit the ability to
reach the response center or receive
emergency service support. Enrollment
and Telematics Subscription Service
Agreement required. A variety of sub-
scription terms is available; charges vary
by subscription term selected and loca-
tion.
●Automatic Collision Notification, Emer-
gency Assistance and Stolen Vehicle
Location will function in the United
States, including Hawaii and Alaska,
Puerto Rico and in Canada, and
Enhanced Roadside Assistance will func-
tion in the United States, Puerto Rico and
in Canada.
●Automatic Collision Notification, Emer-
gency Assistance, Stolen Vehicle and
Enhanced Road Assist ance will not func-
tion in the United States Virgin Islands.
For vehicles first sold in the USVI, no
Safety Connect services will function in
and outside the United States Virgin
Islands.
●Safety Connect services are not subject
to section 255 of the Telecommunica-
tions Act and the device is not TTY com-
patible.
■Languages
The Safety Connect response center will
offer support in multiple languages. The
Safety Connect system will offer voice
prompts in English, Spanish, and French.
Please indicate your language of choice
when enrolling.
■When contacting the response center
You may be unable to contact the response
center if the network is busy.
When the engine switch is turned to
IGNITION ON mode, the red indica-
tor light comes on for 2 seconds then
turns off. Afterward, the green indica-
tor light comes on, indicating that the
service is active.
The following indicator light patterns
indicate specific system usage condi-
tions:
 Green indicator light on = Active
service
 Green indicator light flashing =
Safety Connect call in process
 Red indicator light (except at vehi-
cle start-up) = System malfunction
(contact your Lexus dealer)
 No indicator light (off) = Safety
Connect service not active
■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 vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the agent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
Safety Connect LED light Indi-
cators

Vehicle status information and indicators
speed, a ring-shaped indicator will be
displayed on the tachometer.
The desired engine speed at which the Rev
indicator will begin to be displayed can be
set on of the multi-information display.
(  P.81)
■Rev peak (F SPORT models)
The engine speed reaches or exceeds
5000 rpm, an afterimage of the
tachometer will be displayed at the
highest engine speed for approxi-
mately 1 second.
■The meters and display illuminate when
The engine switch is in IGNITION ON
mode.
■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system
may be malfunctioning. Take your vehicle
to your Lexus dealer.
■Liquid crystal display
Small spots or light sp ots may appear on the
display. This phenomenon is characteristic
of liquid crystal disp lays, and there is no
problem continuing to use the display.
■Customization
The gauges and meters can be customized
on of the multi-information display.
(  P.85)
WARNING
■The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the information display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE
■To prevent damage to the engine and
its components
●Do not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed.
●The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( P.437)
