CAUTION
Seat belt damage and wear
Inappropriate handling of the pretensioner may prevent it from operating
properly resulting in death or serious injury.
Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
Inspect the seat belt system periodically. Check for cuts, fraying, and
loose parts. Do not use a damaged seat belt until it is replaced. Damaged
seat belts cannot protect an occupant from death or serious injury.
Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there's no obvious damage.
Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Seat belt pretensioners
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 any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.

Airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly.
The airbag sensor assembly consists of a safing sensor and an air-
bag sensor.
In certain types of severe frontal or side impacts, the SRS airbag
system triggers the airbag inflators. A chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants. Knee airbags

CAUTION
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 engine, 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 vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, immedi-
ately if this occurs.
Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (P. 425)
*:These lights turn on when the “ENGINE START STOP” switch is
turned to IGNITION ON mode to indicate that a system check is
being performed. They will turn off after the engine is started, or
after a few seconds. There may be a malfunction in a system if a
light does not come on, or if the lights do not turn off. Have the
vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for details

Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following
situations:
Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
Warning lights, messages and buzzers for dynamic radar cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving. (P.
425, 431)
