CAUTION■
Before using dynamic radar cruise control
Do not overly rely on vehicle- to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes etc.■
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.●
Assisting the driver to measure following distance
The dynamic radar cruise control is only in tended to help the driver in determin-
ing the following distance between the driver's own vehicle 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 assi st the driver in low-visibility conditions. It
is still necessary for driver to pay clos e attention to the vehicle's surroundings.●
Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following distance
between the driver's own vehicle and a designated vehicle traveling ahead is
appropriate or not. It is not capable of making any other type of judgement.
Therefore, it is absolutely necessary for the driver to remain vigilant and to deter-
mine whether or not there is a possibil ity of danger in any given situation.●
Assisting the driver to operate the vehicle
The dynamic radar cruise control has no 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 vehicle and act appropriately in
order to ensure the safety of all involved.■
To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.

When driving CAUTION■
Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise contro l in any of the following situations.
Doing so may result in inappropriate sp eed control and could cause an accident
resulting in death or serious injury. ●
In heavy traffic●
On roads with sharp bends●
On winding roads●
On slippery roads, such as thos e covered 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 expressways●
When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, sn ow, sandstorm, heavy rain, etc.)●
When an approach warning buzzer is heard often●
When your vehicle is towing a trailer or during emergency towing■
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (  P. 237) will not be activated, and a fatal or serious accident
may result. ●
Vehicles that cut in suddenly●
Vehicles traveling at low speeds●
Vehicles that are not moving
●
Vehicles with small rear ends (tra ilers with no load on board etc.)
●
Motorcycles traveling in the same lane

2442-4. Using other driving systems
CAUTION■
Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the foll owing conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result: ●
When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor●
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)●
When the road curves or when the lanes are narrow●
When steering wheel operation or your position in the lane is unstable●
When the vehicle ahead of you decelerates suddenly■
Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function co rrectly and could result in an accident.●
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.●
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.●
Do not disassemble the sensor.●
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●
Do not modify or paint the sensor and grille cover.
●
Do not replace them with non-genuine parts.

When driving Intuitive parking assist The distance to obstacles measured by the sensors is communicated via
the multi-information display, screen (vehicles with the Lexus Display
Audio system) and a buzzer when parallel parking or maneuvering into a
garage is conducted. Always check the surrounding area when using this
system.
■ Types of sensors
