WARNING
●Assisting the driver to measure follow- ing distance
The dynamic radar cruise control with
full-speed range is on ly intended to help
the driver in determ ining the following
distance between the driver’s own vehi-
cle and a designated vehicle traveling
ahead. It is not a mechanism that allows
careless or inattentive driving, and it is
not a system that can assist the driver in
low-visibility conditions. It is still neces-
sary for driver to pay close attention to
the vehicle’s surroundings.
●Assisting the driver to judge proper following distance
The dynamic radar cruise control with
full-speed range determines whether the
following distance between the driver’s
own vehicle and a designated vehicle
traveling ahead is within a set range. It is
not capable of making any other type of
judgement. Therefore, it is absolutely
necessary for the driver to remain vigi-
lant and to determine whether or not
there is a possibility of danger in any
given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range has limited capability to
prevent or avoid a collision with a vehicle
traveling ahead. Therefore, if there is
ever any danger, the driver must take
immediate and direct control of the vehi-
cle and act appropriately in order to
ensure the safety of all involved.
■To avoid inadvertent dynamic radar cruise control with full-speed range
activation
Switch the dynamic radar cruise control
with full-speed range off using the cruise control main switch when not in use.
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control
with full-speed range in any of the follow- ing situations.
Doing so may result in inappropriate speed control and could cause an acci-dent resulting in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those cov- ered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sen-sors from detecting correctly (fog,
snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or camera sensor
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●During emergency towing

●The shift position is in D.
●LC500: Range 4 or higher of D has been selected by using the paddle shift.
●Vehicle speed is above approximately 40 km/h (25 mph).
■Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
●Even without canceling the cruise con-
trol, the set speed can be increased by first accelerating the vehicle to the desired speed and then pressing the -
/SET switch to set the new speed.
■Automatic cruise control cancelation
Cruise control will stop maintaining the
vehicle speed in any of the following situa- tions.
●Actual vehicle speed falls more than approximately 16 km/h (10 mph) below the preset vehicle speed.
●Actual vehicle speed is below approxi-mately 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.
■If the warning message for the cruise control is shown on the multi-informa-tion display
Press the cruise control main switch once to deactivate the system, and then press the
switch again to reactivate the system. If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a mal- function in the cruise control system. Have the vehicle inspected by authorized Lexus
retailer or Lexus authorized repairer, or any
reliable repairer.
WARNING
■To avoid operating the cruise control
by mistake
Switch the cruise control off using the
cruise control main switch when not in use.
■Situations unsuitable for cruise con-trol
Do not use cruise control in any of the following situations.
Doing so may result in loss of control and could cause an accident resulting in death or serious injury.
●In heavy traffic

• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch
is turned off once and turned to IGNI- TION ON mode again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding environment may affect the ability of the sensor to correctly detect
obstacles. Particular instances where this may occur are listed below.• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, or on grass. • The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor in the vicinity.• The sensor is splashed with water or
heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rap-idly from behind into a blind spot. Do not
overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to
an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
