Stow the seat belt buckle in the
pockets.
■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.

WARNING
■Adjustable shoulder anchor
Always make sure the shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve or
accident.

cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
WARNING
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
■Seat belt pretensioners
●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 seat belt pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.
●If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

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.

■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.51)
*6: In case the indicator light is not illuminated, consult this manual on how to install the child
restraint system properly. ( P.48)
