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 turn to IGNITION ON mode, this could mean that these sys-
tems 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 the indicated
vehicle’s systems. ( →P. 5 3 4 )
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is on, or after a few seconds.
There may be a malfunction in a system if the lights do not come on, or
turn off. Have the vehicle inspected by your Lexus dealer.

Example of follow-up cruising
When following a vehicle driving slower than the set speed
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 there are no longer vehicles driving slower than the set speed in
the lane ahead
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.
Approach warningWhen your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display will
flash and a buzzer will sound to alert the driver. An example of this would
be if another driver cuts in front of you while you are following a vehicle.
Apply the brakes to ensure an appropriate vehicle-to-vehicle distance.
■Warning lights and messages for dynamic radar cruise control
Warning lights, messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( →P. 5 4 7 )
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehic le control mode. Turn the system off by
pressing the “ON-OFF” button, and turn it on again.

■Conditions that may trigger the system even if there is no possibility 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 a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
●When an extreme change in vehicle height occurs
●When there is an abnormality in the radar sensor
●When climbing a steep hill causes an overhead billboard or other metallic struc-
ture to appear directly in the vehicle’s line of travel
●When passing through certain ETC (Electronic Toll Collection system) gates
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.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( →P. 535, 546)
