WARNING
■Front passenger occupant classifica-
tion system precautions
Observe the following precautions 
regarding the front passenger occupant 
classification system. 
Failure to do so may cause death or seri-
ous injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat 
belt plate has not been left inserted 
into the buckle before someone sits in 
the front passenger seat.

For safety and security
WARNING
●Make sure the “AIR BAG OFF” indica-
tor light is not illuminated when using 
the seat belt extender for the front pas-
senger seat. If the “AIR BAG OFF” 
indicator light is illuminated, discon-
nect the extender tongue from the seat 
belt buckle, and reconnect the seat 
belt. Reconnect the seat belt extender 
after making sure the “AIR BAG ON” 
indicator light is illu minated. If you use 
the seat belt extender while the “AIR 
BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front 
passenger will not activate, which 
could cause death or serious injury in 
the event of a collision.
●Do not apply a heavy load to the front 
passenger seat or equipment (e.g. 
seatback pocket or armrest).
●Do not put weight on the front passen-
ger seat by putting your hands or feet 
on the front passenger seat seatback 
from the rear passenger seat.
●Do not let a rear passenger lift the 
front passenger seat  with their feet or 
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger 
seatback so far that it touches a rear 
seat. This may cause the “AIR BAG 
OFF” indicator light to be illuminated, 
which indicates that the SRS airbags 
for the front passenger will not activate 
in the event of a severe accident. If the 
seatback touches the rear seat, return 
the seatback to a position where it 
does not touch the rear seat. Keep the 
front passenger seatback as upright as 
possible when the vehicle is moving. 
Reclining the seatback excessively 
may lessen the effectiveness of the 
seat belt system.
●If an adult sits in the front passenger 
seat, the “AIR BAG  ON” indicator light 
is illuminated. If the “AIR BAG OFF” 
indicator is illuminated, ask the passen-
ger to sit up straight, well back in the 
seat, feet on the floor, and with the seat 
belt worn correctly. If the “AIR BAG 
OFF” indicator still remains illumi-
nated, either ask the passenger to 
move to the rear seat, or if that is not 
possible, move the front passenger 
seat fully rearward.
●When it is unavoidable to install a for-
ward-facing child re straint system on 
the front passenger seat, install the 
child restraint system on the front pas-
senger seat in the proper order. 
(  P.45)
●Do not modify or remove the front 
seats.
●Do not kick the front passenger seat or 
subject it to severe impact. Otherwise, 
the SRS warning light may come on to 
indicate a malfunction of the front pas-
senger occupant clas sification system. 
In this case, contact your Lexus dealer 
immediately.
●Child restraint systems installed on the 
rear seat should not contact the front 
seatbacks.
●Do not use a seat accessory, such as a 
cushion and seat cover, that covers the 
seat cushion surface.
●Do not modify or replace the uphol-
stery of the front seat.

■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the 
front passenger seat, the system may not re cognize him/her as an adult depending on 
his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt
*4: For some children, child in se at, child in booster seat or child in convertible seat, the sys-
tem may not recognize him/her as a child. Factors which may affect this can be the phy-
sique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger seat. A forward-
facing child restraint system sh ould only be installed on the front passenger seat when it 
is unavoidable. ( P.45)

461-2. Child safety
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions.
Failure to do so may result in death or 
serious injury.
●Never install a re ar-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 to the most 
upright position, move the seat as far 
back as possible, and raise the seat to 
the highest position, even if the “AIR 
BAG OFF” indicator light is illumi-
nated. 
If the head restraint interferes with the 
installation of the ch ild restraint system, 
and the head restraint can be 
removed, remove the head restraint. 
Otherwise, put the  head restraint in 
the upper most position.
●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.

■Automatic Collision Notification
In case of either airbag deployment or 
severe rear-end collision, the system is 
designed to automatically call the 
response center. The responding agent 
receives the vehicle’s location and 
attempts to speak with the vehicle 
occupants to assess the level of emer-
gency. If the occupants are unable to 
communicate, the ag ent automatically 
treats the call as an emergency, con-
tacts the nearest emergency services 
provider to describe the situation, and 
requests that assistance be sent to the 
location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Connect 
can work with local authorities to assist 
them in locating and recovering the 
vehicle. After filing a police report, call 
the Safety Connect response center at  1-800-25-LEXUS (1-800-255-
3987) in the United States, 1-877-
539-8777 in Puerto Rico or 1-800-
265-3987 in Canada, and follow the 
prompts for Safety Connect to initiate 
this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle, 
Safety-Connect-equipped vehicle 
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further 
information is available at Lexus.com.
■Emergency Assistance Button 
(“SOS”)
In the event of an emergency on the 
road, push the “SOS” button to reach 
the Safety Connect response center. 
The answering agent will determine 
your vehicle’s location, assess the 
emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button, 
tell the response-center agent that you are 
not experiencing an emergency.
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds 
GPS data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” but-
ton to reach a Safety Connect 
response-center agent, who can help 
with a wide range of needs, such as: 
towing, flat tire, fuel delivery, etc. For a 
description of the Roadside Assistance 
services and their limitations, please 
see the Safety Connect Terms and 
Conditions, which are available at

immediately.
Driving assist systems
To keep safety and performance, 
the following systems operate auto-
matically in response to various 
driving situations. Be aware, how-
ever, that these systems are supple-
mentary and should not be relied 
upon too heavily when operating 
the vehicle.
Summary of the driving assist 
systems 

2344-5. Using the driving support systems
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its 
straight forward position, but this will be 
corrected automatically when driving.
■Sounds and vibrations caused by the 
ABS, brake assist, VS C, TRAC, hill-start 
assist control and VGRS systems
●A sound may be heard from the engine 
compartment when the brake pedal is 
depressed repeatedly, when the engine is 
started or just after the vehicle begins to 
move. This sound does not indicate that a 
malfunction has occurred in any of these 
systems.
●Any of the following conditions may 
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle  body and steering.
• A motor sound may be heard after the 
vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the 
following cases, but it  does not indicate that 
a malfunction has occurred.
●Operating sound heard from the engine 
compartment when the brake pedal is 
operated.
●Motor sound of the brake system heard 
from the front part of the vehicle when 
the driver’s door is opened.
●Operating sound heard from the engine 
compartment when one or two minutes 
passed after the stop of the engine 
■EPS, VGRS and DRS operation sound
When the steering wheel is operated, a 
motor sound (whirring sound) may be 
heard. This does not indicate a malfunction.
■Automatic reactivation of TRAC and 
VSC systems
After turning the TRAC and VSC systems 
off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch 
is turned off
●If only the TRAC system is turned off, the 
TRAC will turn on when vehicle speed 
increases
If both the TRAC and VSC systems are 
turned off, automatic re-enabling will not 
occur when vehicle speed increases.
■Secondary Collision Brake operating 
conditions
The vehicle speed is approximately 6 mph 
(10 km/h) or more and the airbag sensor 
detects a collision. (The Secondary Colli-
sion Brake will not operate when the vehicle 
speed is below approximately 6 mph [10 
km/h].)
■Secondary Collision Brake automatic 
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations.
●The vehicle speed drops below approxi-
mately 6 mph (10 km/h)
●A certain amount of time elapses during 
operation
●The accelerator pedal is depressed a 
large amount
■If “Secondary Collision Brake system 
Malfunction” is displayed on the multi-
information display
The system may be ma lfunctioning. Have 
the vehicle inspected at your Lexus dealer.
■Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is 
reduced to prevent the system from over-
heating when there is frequent steering 
input over an extended period of time. The 
steering wheel may feel heavy as a result. 
Should this occur, re frain from excessive 
steering input or stop the vehicle and turn 
the engine 
tem should return to normal within 10 min-
utes.
