■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
seats, the glove box, parts of the front and re ar pillars, and roof side rails may be hot for
several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Lexus Enform Safety Connect subscribers, if the SRS airbags deploy or in the event
of a severe rear-end collision, the system is designed to send an emergency call to the
response center, notifying them of the vehicle’s location (without needing to push the
“SOS” button) and an agent will attempt to speak with the occupants to ascertain the
level of emergency and assistance required . If the occupants are unable to communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( →P. 352)
■SRS airbag deployment cond itions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force correspondin g to an approximately 12 - 18 mph [20 -
30 km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be cons iderably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possi ble that only the seat belt pretensioners will
activate.
●The SRS front airbags for the fr ont passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the seat is unoccupied. ( →P. 52)
■SRS airbag deployment conditions (S RS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [15 00 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS curtain shield airbags will deploy in the event of vehicle rollover.
●The SRS side and curtain shield airbags may al so deploy in the event of a severe frontal
collision.

■When to contact your Lexus dealer
In the following cases, the ve hicle will require inspection and/or repair. Contact your
Lexus dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident that
was not severe enough to cause the SRS front
airbags to inflate.
●A portion of a door or its surrounding area is
damaged or deformed, or the vehicle was
involved in an acciden t that was not severe
enough to cause the SRS side and curtain
shield airbags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag, lower
portion of the instrument panel or door of the
glove box is scratched, cracked, or otherwise
damaged.
●The surface of the seats with the side airbag is
scratched, cracked, or otherwise damaged.
●The portion of the front pillars, rear pillars or
roof side rail garnishes (padding) containing
the curtain shield airbags inside is scratched,
cracked, or otherwise damaged.

■Boost meter/oil temperature gauge/oil pressure gauge (GS300)
The boost pressure, engine oil tem-
perature and oil pressure can be dis-
played.Boost meter
When the boost pressure reaches
15 psi (100 kPa) or higher, the color
changes to amber.

■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a battery terminal is disconnected and
reconnected, the steering amount display may
be disabled temporarily. Afte r driving the vehicle for a while , the display will be enabled.

WARNING
■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■Cautions during setting up the display
As the engine needs to be operating during setting up the display, ensure that the vehi-
cle is parked in a place with adequate ventil ation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.

■Start-up display
When the engine is started, the name of the
vehicle is displayed on the multi-information
display.
While the start-up display is being displaye d, the meter display cannot be changed even
if the drive mode is changed. When the start- up display is finished, the meter display for
the currently selected mode will be displayed.
■Torque distribution display
Torque distribution may not be displayed correctly in some cases, such as when the vehi-
cle passes over road expansion joints.
■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●The steering amount, accelerator pedal input, and brake fluid pressure displays are dis-
abled until the engine has warmed up (the variable red zone of the tachometer has
retracted to 7300 rpm).
After the engine has warmed up, these displays will be enabled.
●Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a battery terminal is disconnected and reconnected, the steering amount display may
be disabled temporarily. Afte r driving the vehicle for a while , the display will be enabled.
■Suspension of the settings display
In the following situations, op eration of the settings display will be temporarily sus-
pended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The following information data will be reset:
●Lap timer: Measured lap times, history
●G-force: Record of the maximum G-forces
■Using the lap timer
If the engine is stopped while a lap is being timed, the lap timer will stop and the lap time
up to that point will be recorded.
