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

When driving

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)

2-4. Using other driving systems
IS F_EE
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 an overhead billboard or other metallic structure appears to be in
the vehicle’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.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 425,
431)
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.
