CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag 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 your Lexus dealer immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. ( P. 329)
*: These lights turn on when the engi ne switch is turned to IG-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 mal-
function in a system if a light does no t come on, or if the lights do not turn
off. Have the vehicle inspected by your Lexus dealer.

2-4. Using other driving systems
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration (when ther e are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
62 mph (100 km/h) and the vehicle ahead driving at 50 mph (80 km/
h) is out of the lane
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
■Dynamic radar cruise control warning lights, display and buzzers
Warning lights, display and buzzers are used to indicate a system malfunction or to
alert you to the need for caution while driving. ( P. 3 3 4 )
■The dynamic radar cruise can be set when
●The shift lever is in D or the 4, 5 or 6 range of S.
●Vehicle speed is between approximately 27 mph (43 km/h) and 87 mph (139
km/h).
■Accelerating
The vehicle can be accelerated normally.
■Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations.
●Vehicle speed falls below 25 mph (40 km/h)
●VSC is activated
●The sensor cannot operate correctly because it is covered in some way.*
●The windshield wipers are operating at high speed.*
●The ECT SNOW switch is set to snow mode.*
*
: Vehicle-to-vehicle distance control driving must be reset by turning the ON-OFF button on again.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

●Seat belt (linked to the radar sensor)
• Vehicle speed is above 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncomingvehicle exceeds 18 to 24 mph (30 to 40 km/h).
• The front occupants are wearing a seat belt.
●Seat belts (linked to brake operation)
• Vehicle speed exceeds 9 mph (15 km/h).
• The system detects sudd en braking or skidding.
• The front occupants are wearing a seat belt.
●Brake Assist
• Vehicle speed is above 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle is greater than 18 to 24 mph (30 to 40 km/h).
• The brake pedal is depressed.
■Conditions that may trigger the system even if there is no danger of collision
●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 left-turn
●When your vehicle rapidly closes on the vehicle in front
When the system is activated in the situations described above there is also a possi-
bility 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.
