LS600h/LS600hL_EE(OM50G20E)
CAUTION
■Before using dynamic radar cruise control with full-speed range
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 with full-speed range is only intended to help
the driver in determining the following distance between the driver’s own vehicle
and a designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can assist the driver in low-vis-
ibility conditions. It is still necessary 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 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 determine whether or not there is a possibility of danger in any given situa-
tion.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has no capability to pre-
vent 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.

CAUTION
■To avoid inadvertent dynamic radar cruise control with full-speed range activa-
tion
Switch the cruise control off using the “ON•OFF” button when not in use.
■Situations unsuitable for dynamic rada r 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 accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those 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

CAUTION
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly 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 any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●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.
●If the radar sensor needs to be replaced, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
