1-1.For safe use
Use only floor mats designed specifi-
cally for vehicles of the same model
and model year as your vehicle. Fix
them securely in place onto the carpet.
1Insert the retaining hooks (clips)
into the floor mat eyelets.
2 Turn the upper knob of each retain-
ing hook (clip) to secure the floor
mats in place.
Always align the marks .
The shape of the reta ining hooks (clips)
may differ from that shown in the illustra-
tion.
Before driving
Observe the following before start-
ing off in the vehicle to ensure
safety of driving.
Installing floor mats
A
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s
floor mat to slip, poss ibly interfering with
the pedals while driv ing. An unexpect-
edly high speed may result or it may
become difficult to stop the vehicle. This
could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for
other models or different model year
vehicles, even if they are Lexus Genu-
ine floor mats.
●Only use floor mats designed for the
driver’s seat.
●Always install the floor mat securely
using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on
top of each other.
●Do not place the floor mat bottom-
side up or upside-down.
■Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this
check after cleaning the floor.
●With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

Driver’s seat belt buckle switch
Airbag sensor assembly
“AIR BAG ON” and “AIR BAG OFF” indicator lights
Front passenger’s seat belt buckle switch
Front impact sensors
Your vehicle is equipped with ADVA NCED 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 sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant info rmation. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-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.
●All of the doors will be unlocked.
(  P.96)
●The brakes and stop lights will be con-
trolled automatically. ( P.246)
●The interior lights will turn on automati-
cally. ( P.275)
●The emergency flashers will turn on auto-
matically. ( P.352)
●Fuel supply to the engine will be stopped.
( P.360)
●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.
(
 P.55)
• 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 situ-
ations:
• 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 the seat belt preten-

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 running 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.
