■ Active roll bar precautions
● Before scrapping your vehicle, make
sure to contact your Lexus dealer.
● If the active roll bar operates when the
soft top roof is opened, the soft top roof
cannot be closed.
● The active roll bar cannot be reused once
it has operated. Have it replaced by your
Lexus dealer.
■ Active roll bar operational conditions
● The active roll bar operate regardless of
the opening/closing state of the soft top
roof.
● The active roll bar will operates in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12 - 18
mph [20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform, or the impact force produced by
an approximately 3300 lb. [1500 kg]
vehicle colliding with the vehicle cabin
from a direction perpendicular to the
vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
However, this threshold velocity will be
considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a
parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride
collision, such as a collision in which the
front of the vehicle underrides, or goes
under, the bed of a truck
● The active roll bar operates when the
vehicle rolls over.
● The active roll bar may also operate if a
serious impact occurs to the underside of
the vehicle, such as in the following situa-
tion.
•Hitting a curb, edge of pavement or hard
surface
• Falling into or jumping over a deep hole
• Landing hard or falling
• The vehicle is leaning considerably to
one side.
• The vehicle is subjected to certain types
of severe impacts when the vehicle has
slided sideways and collided with a curb,
etc.
■ Conditions under which the active roll
bar may not operate
The active roll bar does not generally oper-
ate if the vehicle is involved in a rear colli-
sion, or if it is involved in a low-speed frontal
or side collision. But, whenever a collision of
any type causes sufficient forward deceler-
ation of the vehicle, operation of the active
roll bar may occur.
● Collision from the rear
● Collision from the side to the vehicle
body other than the passenger compart-
ment
● Collision from the side at an angle
■ When the active roll bar operates
The soft top roof cannot be opened or
closed while the active roll bar is operating.
