Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US 
motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU) 
controls airbag deployment  based on information obtained from the sensors etc. 
shown in the system components diagram  above. This information includes crash 
severity and occupant information. As the airbags deploy, a chemical reaction in 
the inflators quickly fills the airbags with no n-toxic gas to help restrain the motion of 
the occupants.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may 
be sustained from SRS airbags, due to the 
extremely high speed deployment (infla-
tion) 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 seat s, parts of the front 
and rear pillars, and r oof side rails may be 
hot for several minutes. The airbag itself 
may also be hot.
●The windshield may crack.
●The interior lights will turn on automati-
cally. ( P.265)
●The emergency flashers will turn on auto-
matically. ( P.350)
●For Lexus Enform Safety Connect sub-
scribers, if any of the following situations 
occur, 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” but-
ton) and an agent will attempt to speak 
with the occupants to ascertain the level 
of emergency and assi stance required. If 
the occupants are unable to communi-
cate, the agent automatically treats the 
call as an emergency and helps to dis-
patch the necessary  emergency ser- vices.(

• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
■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 corre-
sponding 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 situa-
tions:
• 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 
possible that only th e seat belt preten-
sioners and SRS knee  airbags will acti-
vate.
●The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat. 
However, the SRS front airbags for the 
front passenger may deploy if luggage is

inside is scratched, cracked, or otherwise 
damaged.
WARNING
■SRS airbag precautions
Observe the following precautions 
regarding the SRS airbags. 
Failure to do so may cause death or seri-
ous 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 air-
bag is the first 2 - 3 in. (50 - 75 mm) of 
inflation, 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 breast-
bone. 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 
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 recom-
mended by NHTSA above, while still 
maintaining control of the foot pedals, 
steering wheel, and your view of the 
instrument panel controls.

WARNING
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower 
portion of the instrument panel. 
These items can become projectiles 
when the SRS driver, front passenger 
and knee airbags deploy.
●Do not attach anything to areas such 
as a door, windshield, side window, 
front or rear pillar, roof side rail and 
assist grip.
●Do not hang coat hangers or other 
hard objects on the coat hooks. All of 
these items could become projectiles 
and may cause death or serious injury, 
should the SRS curtain shield airbags 
deploy.
●If a vinyl cover is put on the area where 
the SRS knee airbag will deploy, be 
sure to remove it.
●Do not use seat accessories which 
cover the parts where the SRS side air-
bags inflate as they may interfere with 
inflation of the SRS airbags. Such 
accessories may prevent the side air-
bags from activating correctly, disable 
the system or cause the side airbags to 
inflate accidentally, resulting in death 
or serious injury.
●Do not strike or apply significant levels 
of force to the area of the SRS airbag 
components or the front doors. 
Doing so can cause the SRS airbags to 
malfunction.
●Do not touch any of the component 
parts immediately  after the SRS air-
bags have deployed  (inflated) as they 
may be hot.
●If breathing becomes difficult after the 
SRS airbags have deployed, open a 
door or window to allow fresh air in, or 
leave the vehicle if it is safe to do so. 
Wash off any residue as soon as possi-
ble to prevent skin irritation.
●If the areas where the SRS airbags are 
stored, such as the steering wheel pad 
and front and rear pillar garnishes are 
damaged or cracked, have them 
replaced by your Lexus dealer.
●Do not place anything, such as a cush-
ion, on the front passenger’s seat. 
Doing so will disperse the passenger’s 
weight, which prevents the sensor 
from detecting the passenger’s weight 
properly. As a result, the SRS front air-
bags for the front passenger may not 
deploy in the event of a collision.
■Modification and disposal of SRS air-
bag system components
Do not dispose of your vehicle or per-
form any of the following modifications 
without consulting your Lexus dealer. 
The SRS airbags may malfunction or 
deploy (inflate) accidentally, causing 
death or serious injury.
●Installation, removal, disassembly and 
repair of the SRS airbags
●Repairs, modifications, removal or 
replacement of the steering wheel, 
instrument panel, dashboard, seats or 
seat upholstery, front, side and rear pil-
lars, roof side rails, front door panels, 
front door trims or front door speakers
●Modifications to the front door panel 
(such as making a hole in it)

For safety and security
Adjust the lumbar support to the 
lowest position.
 Adjust the pelvic support
* to the 
lowest position.
 If the head restraint interferes with 
the child restraint system installa-
tion and the head restraint can be 
removed, remove the head restraint. 
Otherwise, put the head restraint in 
the upper most position.
*: If equipped
WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or 
serious injury.
●Never install a rear-facing child 
restraint system on the front passenger 
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of 
an accident, the force of the rapid infla-
tion of the front passenger airbag can 
cause death or serious injury to the 
child if the rear-facing child restraint 
system is installed on the front passen-
ger seat.
●A forward-facing child restraint system 
may be installed on the front passen-
ger seat only when it is unavoidable. A 
child restraint system  that requires a 
top tether strap should not be used in 
the front passenger seat since there is 
no top tether strap anchor for the front 
passenger seat.
●A forward-facing child restraint system 
may be installed on the front passen-
ger seat only when  it is unavoidable. 
When installing a forward-facing child 
restraint system on  the front passenger 
seat, adjust the seatback angle to the 
most upright position, move the seat to 
the rearmost position, and raise the 
seat to the upper most  position, even if 
the “AIR BAG OFF” indicator light is 
illuminated. 
●Do not allow the child to lean his/her 
head or any part of his/her body 
against the door or th e area of the seat, 
front or rear pillars, or roof side rails 
from which the SRS side airbags or 
SRS curtain shield airbags deploy even 
if the child is seated in the child 
restraint system. It is dangerous if the 
SRS side and curtain shield airbags 
inflate, and the impact could cause 
death or serious injury to the child. 

2585-3. Using the air conditioning system
mode is selected, eco air conditioning 
mode may turn off.
1Press the automatic mode switch or 
select “AUTO” on the sub function 
menu. (P.255)
2
Press the outside/recirculated air 
mode switch to switch to automatic 
air intake mode.
The air conditioning system automatically 
switches between outside air and recircu-
lated air modes.
3Adjust the temperature setting.
4
To stop the operation, press the off 
switch or select “Off” on the sub 
function menu. ( P.255)
If the fan speed setting or air flow 
modes are operated , the automatic 
mode indicator goes off. However, 
automatic mode for functions other 
than that operated is maintained.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the 
ambient conditions.
Therefore, the fan may stop for a while until 
warm or cool air is ready to flow immedi-
ately after the automatic mode switch is 
pressed or “AUTO” is selected.
Cool air may blow around the upper body 
even when the heater is on due to sunlight.
■Windshield fog detection function
When automatic mode is set, the humidity 
sensor detects fog on  the windshield and 
controls the air condit ioning system to pre-
vent fog.
■Automatic mode for air intake control
In automatic mode, the system detects 
exhaust gas and other pollutants and auto-
matically switches between outside air and 
recirculated air modes.
When the dehumidification function is off, 
and the fan is operating, turning automatic 
mode on will activate the dehumidification 
function. The next time the dehumidification 
function is turned off, the AUTO mode for 
switching between outside air and recircu-
lated air modes is canceled.
In S-FLOW mode, priority for the air-
flow is given to the front seats, reducing 
the airflow and air conditioning effect 
WARNING
■To prevent burns (vehicles with wind-
shield wiper de-icer)
Do not touch the glass at lower part of 
the windshield or to the side of the front 
pillars when the wind shield wiper de-icer
