■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on when
you start the hybrid system, this could mean that these systems are not available to help
protect you in an accident, which could result in death or serious injury. Have the vehi-
cle inspected by any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately if this occurs.

◆Pre-crash braking*3
When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
collision is extremely high, the brakes are automatically applied to help avoid
the collision or reduce the collision speed.
*3: Depending on the region in which the vehicle was sold, the pre-crash braking function may not be available.
◆Suspension control (if equipped)
When the system determines that the possibility of a frontal collision is high,
the Adaptive Variable Suspension system ( →P. 345) will control the damping
force of the shock absorbers.
◆Steering control (if equipped)
When the system determines that the possibility of a frontal collision is high
and the driver is operating the steering wheel, the LDH system ( →P. 345) will
control the turning angle of the front an d rear wheels and effort necessary to
turn the steering wheel.

■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not pr event collisions or lessen collision damage
or injury in every situation. Do not overly rely on this system. Failure to do so may lead
to an accident, resulting in death or serious injury.
●Although this system is designed to help av oid a collision or help reduce the impact of
the collision, its effectiveness may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may oper ate even if there is no possibility of a
collision: →P. 2 7 5
• Conditions under which the system may not operate properly: →P. 2 7 8
●Do not attempt to test the operation of the pre-crash safety system yourself, as the
system may not operate properly, possibly leading to an accident.
