CAUTION
When installing a child restraint system
For Russia
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for the child restraint system installa-
tion.
When a junior seat is installed, always ensure that the 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. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, choking or other serious injuries may result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.

CAUTION
When installing a child restraint system
Make sure the outside rear seat head restraints are not in the folded posi-
tion.
Ensure that the belt and tab are securely locked and the seat belt is not
twisted.
Push and pull the child seat from side to side and forward to be sure it is
secure.
Follow all installation instructions provided by the child restraint system
manufacturer.
To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint. Make sure the child restraint system is securely attached, or it may
cause death or serious injury to the child or other passengers in the event of
a sudden stop, sudden swerve or accident.

PCS (Pre-Crash Safety system)
When the radar sensor detects possibility of a frontal collision, the pre-
crash safety system such as the brakes and seat belts are automatically
engaged to lessen impact and injuries to occupants as well as vehicle
damage.
Pre-crash seat belts
If the pre-crash sensor detects that a collision is unavoidable, the
pre-crash safety system will retract the seat belt before the collision
occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 7 6 )
However, the system will not operate in the event of skidding when
the VSC systems are disabled.
Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
Pre-crash braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer.
If the system determines that a collision is unavoidable, the brakes
are automatically applied to reduce the collision speed. The pre-

The pre-crash safety system is operational when
Pre-crash seat belts (type A):
• Vehicle speed is above 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or oncom-
ing vehicle exceeds 30 to 40 km/h (19 to 25 mph).
• The front occupants are wearing a seat belt.
Pre-crash seat belts (type B):
• Vehicle speed exceeds 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash brake assist:
• Vehicle speed is above 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than 30 to 40 km/h (19 to 25
mph).
• The brake pedal is depressed.
Pre-crash braking:
• The pre-crash braking function is activated.
• Vehicle speed is above 15 km/h (10 mph).
• The relative speed difference between your vehicle and another vehi-
cle that is forward of your vehicle, or the speed at which your vehicle
is approaching an obstacle is greater than 15 km/h (10 mph).
Conditions that may trigger the system even if there is no possibility of col-
lision
When there is an object by the roadside at the entrance to a curve
When passing an oncoming vehicle on a curve
When driving over a narrow iron bridge
When there is a metal object on the road surface
When driving on an uneven road surface
When passing an oncoming vehicle on a right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel.

When driving
IS250/220d/200d_EE
When a billboard or other metallic structure appears to be in the vehi-
cle’s direct line of travel due to driving on a hill.
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When driving on a bridge.
When the system is activated in the situations described above there is also a
possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
