6-3. Reducing impact to the occupants in a collision

Driving support system
6-3.Reducing imp act to the occupants in a co llision
When the vehicle is subjected to a
severe frontal or side impact or roll-
over, the pretensioners retract the seat
belts of the front seats and rear outer
seats to securely restrain the occu-
pants.
The pretensioners will not operate in
minor frontal or side impacts, or rear
impacts.
■ 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.
■ PCS-linked control
If the PCS (Pre-Collision System) deter-
mines that the possibility of a collision with a
vehicle is high, the seat belt pretensioners
will be prepared to operate.

WARNING
■ Seat belt pretensioners
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking or an accident. Failure to
do so may result in death or serious
injury.
● 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 operate in the event of a colli-
sion.
● If a pretensioner has operated, the
SRS warning light will illuminate.
In this situation, the seat belt cannot be
used and must be replaced by your
Lexus dealer.
SRS airbags
The SRS airbags deploy when the vehicle is subjected to certain types of
severe impact that may cause significant injury to the occupants. The airbags
work together with the seat belts to help reduce the risk of death or serious
injury.
