retractor, firmly pull the belt and release it.
■
Emergency locking retractor (ELR)
The retractor will lock the belt during a sud-
den stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy
motion will allow the belt to extend so that
you can move around fully.
■
Automatic locking retractor (ALR)
When a passenger’s sh oulder belt is com-
pletely extended and then retracted even
slightly, the belt is locked in that position and
cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt
and then pull the belt out once more.
(  P.45) The front seat belt buckles move out-
ward automatically for easier access. 
When entering the vehicle
When a front door is opened, the seat
belt buckle for the corresponding seat
will move outward automatically. The
buckle will retract automatically after
the plate is inserted and locked to the
buckle. 
When exiting the vehicle (driver’s
seat only)
If the engine switch is turned off when
the driver’s seat belt is fastened, the
driver’s seat belt buckle will move out-
ward. The buckle will retract automati-
cally when the driver’s seat belt is
released. *

■
Easy Access Buckle ●
When the seat belt buckle is in the out-
ward position and not latched, if the front
passenger’s seat is not occupied and the
vehicle is driven, the seat belt buckle will
return to its original position. ●
If an occupant exits the vehicle and leaves
the front door open and then enters the
vehicle again, the seat belt buckle will not
operate until the door is closed and then
opened again.

Airbag sensor assembly

Pop Up Hood computer assembly
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 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.●
All of the doors will be unlocked.

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 assistance 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 services.

• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe
rear-end collision. ■
PCS-linked SRS airbag deployment
control (vehicles with Lexus Safety Sys-
tem + A)
If the PCS (Pre-Collision System) deter-
mines that the possibility of a side collision is
high, the SRS side and curtain shield air-
bags will be prepared to operate.
■
SRS airbag deployment conditions (SRS
front airbags/SRS seat cushion airbags)
●
The SRS front airbags and SRS seat cush-
ion airbags will deploy in the event of an
impact that exceed s the set threshold
level (the level of fo rce 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 threshol d velocity will be
considerably higher in the following situa-
tions:

Pop Up Hood precautions
●
Before scrapping your vehicle, make sure
to contact your Lexus dealer.
●
The Pop Up Hood system cannot be
reused once it has operated. Have it
replaced by your Lexus dealer. ■
PCS-linked Pop Up Hood operation
control
If the PCS (Pre-Collision System) deter-
mines that the possibilit y of a collision with a
pedestrian or bicyclist is high, the Pop Up
Hood will be prepared to operate. ■
Pop Up Hood operational conditions
The Pop Up Hood will operate when the
vehicle detects an impact such as the fol-
lowing: ●
The front bumper detects a frontal impact
equivalent to or grea ter than that of a
pedestrian while the vehicle being driven
within the operational speed range of
approximately 16 to 34 mph (25 to 55
km/h). (The system is operated by an
impact of threshold level or greater, even
in the case of a minor collision that may
not leave a trace on the front bumper.
Also, depending on the impact condi-
tions or vehicle speed, the system may
operate by a collision with a light or small
object or a small animal.) ●
In other situations, such as the following
the system may operate when an impact
is applied to the lower part of the vehicle
or front bumper:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an
undulating road, a pr otruding object or
falling object ■
Conditions under which the Pop Up
Hood may not operate properly ●
If a pedestrian collides with the right or
left corner of the front bumper or the side
of the vehicle. As such impacts may be
difficult to detect, the system may not
operate.
●
If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate
properly.
■
Conditions under which the Pop Up
Hood will not operate
The Pop Up Hood will not operate in the
following situations:
●
Colliding with a lying personPop Up Hood In the event of a frontal collision
with a body, such as a pedestrian,
the Pop Up Hood system raises the
hood to reduce the possibility of a
serious impact to the pedestrian’s
head area by adding clearance to
the engine compartment.
When the sensors located at the
back of the front bumper detect a
frontal impact with a body, such as a
pedestrian, which meets or
exceeds the threshold level while
the vehicle is being driven within
the operational speed range, the
system operates.

LS500_OM_(U)_1810 Exhaust gas precautions Harmful substance to the human
body is included in exhaust gases if
inhaled. WARNING
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard. ■
Important points while driving●
Keep the trunk lid closed.●
If you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.■
When parking●
If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●
Do not leave the vehicle with the
engine on for a long time.
If such a situation cannot be avoided,
park the vehicle in an open space and
ensure that exhaust fumes do not enter
the vehicle interior.
●
Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle. ■
Exhaust pipe
The exhaust system needs to be checked
periodically. If there is a hole or crack
caused by corrosion, damage to a joint
or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired
by your Lexus dealer.
