■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. 329)
■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 corresponding to an approximately 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wa ll 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. 46)
■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 vehicle 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.

■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 12-volt battery terminal is disconnected and reconnected, the steering amount dis-
play may be disabled temporarily. After driv ing the vehicle for a while, the display will
be enabled.
●Depending on the condition of the vehicle, the brake fluid pressure display may change
even when the brake pedal is not depressed.
■System check display
After turning the power switch to ON mode , opening image is displayed while system
operation is checked. When the system check is complete, the normal screen will return.
■Suspension of the settings display

suspended.
●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 power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted.
●“---” may be displayed if the tire 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 reconnect ing 12-volt battery terminals

3-3. Adjusting the seats
■When adjusting the seat
Take care when adjusting the seat so that the head restraint does not touch the ceiling.
■Power easy access system
The driver’s seat and steering wheel move in accordance with power switch mode and
the driver’s seat belt condition. The passenger’s seat moves when the passenger’s door is
opened. ( →P. 145)
WARNING
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.
●Make sure to leave enough space around the feet so they do not get stuck.
■Seat adjustment
To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat
more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shou lder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
