1-4. Adjustable components (seats, mirrors, steering wheel)
■Mirror angle can be adjusted when
The “POWER” switch is in ACCESSORY or ON mode.
■Linked mirror function when reversing (vehicles with driving position memory)
The outside rear view mirrors will automatically angle downwards when the vehicle
i

s reversing in order to give a better view of the ground. However, this function will
not operate when the mirror select switch is in the neutral position (between “L” and
“R”).
■Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it rains, the
r
ain clearing (hydrophilic) effect of the mirrors causes the droplets to be spread out
into a film making the rear view clearer. In the following cases, the rain clearing
effect will be reduced temporarily, but wi ll return after 1 or 2 days’ exposure to
direct sunlight.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After waxing your vehicle in an automatic car wash
●After your vehicle has been parked for a long period in underground parking
lots etc. where there is no direct sunlight
■When the mirrors are fogged up
Turn on the mirror defoggers to defog the mirrors. ( P.
2 6 0 )
■Automatic adjustment of the mirror angle (vehicles with driving position mem -
ory)
A desired mirror face angle can be entered to memory and recalled automatically
b
y the driving position memory. ( P. 6 8)
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirr or is
set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view mir -
ror to reduce reflected light. ( P. 8 1 )

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 turnin g on the mirror defoggers or by applying
warm water.

Correct driving posture
Drive with a good posture as follows:
Sit upright and well back in
the seat. ( P. 6 4 )
Adjust the position of the seat
forward or backward to
ensur
e the pedals can be
reached and easily
depressed to the extent
required. ( P. 6 4 )
Adjust the seatback so that
the controls are easily opera -
ble. ( P. 6 4)
Adjust the tilt and telescopic
positions of the steering
wheel do
wnward so the air -
bag is facing your chest. 
( P. 7 9 )
Lock the head restraint in
place with the center of the
head r
estraint closest to the
top of your ears. ( P. 7 1 )
Wear the seat belt correctly.

1-8. Safety information
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airb ag sensor as
sembly. 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 s
ystem
triggers the airbag inflators. A chemica l 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 abrasion s 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 a 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 obje

ct, 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 thresh ol
d level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.

■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible. Do not dis-
connect the 12-volt battery cables before contacting your Lexus dealer.
●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 pedals
comfortably.
• Slightly recline the back of the seat.  Although vehicle designs vary, many dr ivers 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, ti lt 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.
