■Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situations:
●Actual vehicle speed is more than approximately 16 km/h (10 mph) below the set vehi-
cle speed.
●Actual vehicle speed falls below approximately 40 km/h (25 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off by pressing the VSC OFF switch.
●Pre-crash braking is activated.
If constant speed control mode is automatically canceled for any other reason, there may be a malfunction in the system. Contact any authorized Lexus dealer or repairer, oranother duly qualified and equipped professional.
■Warning messages and buzzers for dynamic radar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driv ing. If a warning message is shown on the
multi-information display, read the message and follow the instructions.
■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.As the sensor may not be able to correctly detect these types of vehicles, the approach
warning ( P. 336) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)

●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the detecting of the sensor
■Conditions under which the vehicle-to-vehicle distance control mode may not function
correctly
In the case of the following conditions, op erate the brake pedal (or accelerator pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not operate properly.
●When the vehicle ahead of you decelerates suddenly
●When your vehicle is pointing upwards(caused by a heavy load in the luggage com-
partment, etc.)
●Preceding vehicle has an extremely high
ground clearance
●When the road curves or when the lanes are narrow

WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are installed be hind the left and right sides of the rear bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●Do not subject a sensor or its surrounding area on the rear bumper to a strong impact. If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly. In the following situations, have your ve hicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
• A sensor or its surrounding area is subject to a strong impact. • If the surrounding area of a sensor is scratched or dented, or part of them hasbecome disconnected.
●Do not disassemble the sensor.
●Do not attach stickers to the sensor or surrounding area on the rear bumper.
●Do not modify the sensor or surrounding area on the rear bumper.
●Do not paint the rear bumper any color other than an official Lexus color.
●Keep the sensors and the surrounding areas
on the rear bumper clean at all times. If a sensor or its surrounding area on the rearbumper is dirty or covered with snow, the
Blind Spot Monitor may not operate and a warning message ( P. 673) will be dis- played. In this situation, clear off the dirt or
snow and drive the vehicle with the operation conditions of the BSM function ( P. 363) satisfied for approximately 10 minutes. If the

■Conditions under which the BSM function may not function correctly
●The BSM function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround-
ing area • When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area onthe rear bumper
• When driving on a road surface that is wet with standing water during bad weather, such as heavy rain, snow, or fog• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When the distance between your vehicle and a following vehicle is short • When there is a significant difference in speed between your vehicle and the vehiclethat enters the detection area
• When the difference in speed between your vehicle and another vehicle is changing • When a vehicle enters a detection area traveling at about the same speed as yourvehicle
• As your vehicle starts from a stop, a vehicle remains in the detection area • When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces • When vehicle lanes are wide, or when driving on the edge of a lane, and the vehiclein an adjacent lane is far away from your vehicle

that enters the detection area • Immediately after the BSM function is turned on
●Instances of the BSM function unnecessarily detecting a vehicle and/or object mayincrease in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround- ing area• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short • When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehicle traveling in a lane other than the adjacent lanes enters the detection area• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
