WARNING
●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 se at 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.
●If the seat belt extender has been con-
nected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be
sure to wear the seat belt with the seat
belt extender.
●The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright.
●Improperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying airbag.
An infant or child who is too small to
use a seat belt should be properly
secured using a child restraint system.
Lexus strongly recommends that all
infants and children be placed in the
rear seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. (
P.40)

341-1. For safe use
WARNING
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●Do not allow the front seat occupants
to hold items on their knees.
●Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seats toward the door or
put their head or hands outside the
vehicle.
●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 windshield,
front or rear pillar, roof side rail and
assist grip.
●Do not hang coat hangers or 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.

■Removing a child restraint system
installed with a seat belt
Press the buckle release button and
fully retract the seat belt.
When releasing the buckle, the child
restraint system may spring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt automatically reels itself,
slowly return it to the stowing position.
■Child restraint LATCH anchors
LATCH anchors are provided for the
each rear seat. (Buttons displaying the
location of the anchors are attached to
the seats.)
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Do not allow children to play with the
seat belt. If the seat belt becomes
twisted around a child’s neck, it may
lead to choking or other serious inju-
ries that could result in death. If this
occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.
●Ensure that the belt and plate are
securely locked and the seat belt is not
twisted.
●Shake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.
●After securing a child restraint system,
never adjust the seat.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
■When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( P.26)
■Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.

Connect service not active
■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 Con-
nect 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
Lexus.com.
Important! Read this information about
exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.
