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 de celeration/acceleration is not appropriate,
adjust the vehicle speed, as well as the distance between your vehicle and vehicles
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 determining
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 assist the driver in low-visibility conditions . It is still necessary
for driver to pay close attention to the vehicle’s surroundings.
●Assisting the driver to judg e 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 appro-
priate or not. It is not capab le 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 situation.
●Assisting the driver to operate the vehicle
The dynamic radar crui se 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.

CAUTION
■When using the wide view front & side monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●When attempting to use the side camera while the door mirror is folded in, the base
of the door mirror is displayed on the screen and the area in front of the vehicle can-
not be observed. The image displayed on the screen differs depending on the posi-
tion of the door mirror.
●The field of view of the camera is limited. Do not rely solely upon the wide view front &
side monitor.
As with unequipped vehicles, drive carefully while directly confirming the safety of
your surroundings.
●Always check visually to confir m your intended path is clear.
●The camera uses a special lens. The distances between objects and pedestrians that
appear in the image displayed on the screen will differ from the actual distances.
●When the monitor is in front view enlarged display mode, even if obstacles in the
image from the side monitor have disappear ed, do not turn the steering wheel any
further until the vehicle has passed the obstacle. By turning the steering wheel further,
the vehicle may make a tight turn, causing the vehicle to make contact with the obsta-
cle.
●Do not drive the vehicle while only lookin g at the monitor screen under any circum-
stances.
Driving while only viewing the monitor scr een may cause a collision or lead to an
accident, as the image displa yed on the monitor screen may differ from actual condi-
tions. Make sure to visually check the surrounding areas with and without the mirror
while driving.
●Do not use the wide view front & side monitor in the following cases:
• On icy or slick road surfaces, or in snow.
• When the front passenger’s d oor is not closed completely
• When using tire chains
• On roads that is not flat, such as slopes
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is movi ng, or you may become unable to see the
image on the screen. Be sure to check dire ct visually all around the vehicle before
proceeding.
●If the tires are changed, the position of th e guide lines displayed on the screen may be
incorrect. When changing the tires, consult your Lexus dealer.
●Depending on the circumstances of the ve hicle (number of passengers, amount of
luggage, etc.), the position of the guide lines displayed on the screen may change. Be
sure to check visually behind and all around the vehicle before proceeding.
●When washing the vehicle, do not apply intensive bursts of water to the camera or
camera area. Doing so may result in the camera malfunctioning.

NOTICE
■When a solid object is close by
■When using the wide view front & side monitor
Even if an obstacle is no longer visible on the side monitor, do not turn the steering
wheel further in the direction the vehicle
is turning until the vehicle has moved com-
pletely past the obstacle. If th e steering wheel is turned to full lock, the vehicle will turn
in the smallest possible turning circle, and may collide with the obstacle.
The screen’s guide lines are designed for level
surfaces (road surface etc.) or flat walls etc.
When driving near the obstacle, the obstacle
may be displayed as outside the projected
course line, and it may seem that there is no
danger of a collision, however any sections pro-
truding from the wall may project over the
course line and the vehicle may actually collide
with the obstacle.
In cases such as this were the projected course
line passes close to obst acles, always visually
check the surroundings for safety.
