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
front seats, parts of th e front and rear 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 airb ags 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 vehicl e’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. 4 5 2 )■
SRS airbag deployment conditions (SRS front airbags) ●
The SRS front airbags will deploy in the event of an impact that exceeds the set threshold
level (the level of force corresponding 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 considerably 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 possib le that only the seat belt pretensioners will
activate. ●
The SRS front airbags for the front 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 se at is unoccupied. ( P. 5 1 )●
The SRS seat cushion airbag on the front passenger seat will not operate if the occu-
pant is not wearing a seat belt. ■
SRS airbag deployment conditions (S RS side and curtain shield airbags)●
The SRS side and curtain shield airbags wi ll deploy in the even t of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1 500 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 will deploy in the event of a severe frontal colli-
sion.

When to contact your Lexus dealer
In the following cases, the vehicle will re quire 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 involv ed 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, deformed or has had a hole made in
it, or the vehicle was in volved in an accident
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 or
lower portion of the instrument panel is
scratched, cracked, or otherwise damaged. ●
The front passenger’s seat cushion surface is
scratched, cracked, or otherwise damaged.
●
The surface of the seats with the side airbag is
scratched, cracked, or otherwise damaged.

RX450h_U_OM0E013U ◆ When stopped/during start off
The gasoline engine stops* when the vehi cle is stopped. During start off, the
electric motor (traction mo tor) drives the vehicle. At slow speeds or when
traveling down a gentle slope, the engine is stopped* and the electric motor
(traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is not being
charged.
* : When the hybrid battery (traction battery) requires charging or the engine is warm-
ing up, etc., the gasoline engine will not automatically stop. ( P. 7 8 )
◆ During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆ When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the hybrid bat-
tery (traction battery) is added to that of the gasoline engine via the electric
motor (traction motor).
◆ When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power generator,
and the hybrid battery (tr action battery) is charged.
When the gasoline engine is off while driving, a sound is produced to warn
pedestrians, people riding bicycles or ot her people and vehicles in the surround-
ing area that the vehicle is approaching. The pitch of the sound varies according
to the vehicle speed. When the vehicle speed becomes approximately 15 mph
(25 km/h) or more, the notification sound turns off.Vehicle proximity notification system

Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:●
Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off. ●
Do not touch the high voltage parts, cables and connectors. ●
If electric wires are exposed inside or ou tside your vehicle, an electric shock may
occur. Never touch exposed electric wires. ●
If a fluid leak occurs, do not touch the fluid as it may be strong alkaline electrolyte
from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid
solution. Seek immediate medical attention. ●
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for el ectric fires. Using even a small amount of
water may be dangerous. ●
If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. ( P. 5 3 0 )●
Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as
possible.

Sway warning (if equipped)
Detects the sway of the vehicle within a lane, which is often associated with a
decrease in the driver’s attention level, and displays the decrease in attention
using a bar display.
The shorter the bar length, the more the driver may need to rest. This display is a part of the LDA (Lane Departure Alert with steering control)/LKA
(Lane-Keeping Assist) system. The displa y is enabled when the operating condi-
tions of the vehicle sway warning are met. ( P. 292, 302)■

Displays the driving force applie d to each wheel using segments.
The greater the number of segments displayed, the greater the driving force

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 se at 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 belt during a co llision, do not recline the seat
more than necessary.
If the seat is too rec lined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
