CAUTION
■When driving the vehicle
Observe the following precautions while driving.
Failing to do so may result in loss of control of the vehicle and cause an accident,
resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your hand
caught by the moving mirror.
■When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot and burn
you.
NOTICE
■If the mirrors become iced up (if equipped)
In order to retain the rain-clearing properties of the mirror, do not attempt to scrape
the ice off. Instead, remove it by turning on the mirror defoggers or by applying
warm water.

Before driving
HS250h_U_75033U(Canada)The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●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, parts of the 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 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 communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (
→P. 3 9 5 )
■Operating 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 if the vehicle strikes
an object, such as a parked vehicle and sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.

●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the SRS front passenger airbag may
deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is
unoccupied. (→P. 7 3 )
■Operating conditions (SRS side airbags and curtain shield airbags)
The SRS side airbags and SRS curtain shield airbags will 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 3307 lb. [1500 kg] vehicle colliding
with the vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximately speed of 12 -18 mph [20 -30 km/h]).
■Conditions under which the SRS airbags ma y deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not depl oy the SRS airbags (SRS front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible.
●Any of the SRS airbags has 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 airbags to inflate.
●A portion of a door is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side airbags and curtain
shield airbags to inflate.
●The pad section of the steering wheel,
dashboard near the front passenger airbag
or lower portion of the instrument panel is
scratched, cracked, or otherwise dam-
aged.
●The surface of the front seats and rear seat
side garnishes (padding) with the side air-
bag is scratched, cracked, or otherwise
damaged.
●The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise dam-
aged.

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of infla-
tion, placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedalscomfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are safer for infants and children than the
front passenger seat. (→P. 121)
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle but
the seat belt extender has not also been
fastened to the latch plate of the driver’s
seat belt, the SRS driver airbag system will
judge that the driver is wearing the seat belt
even though the seat belt has not been
connected. In this case, the SRS driver
airbag may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.
