STARTING AND DRIVING
376The selector lever must be in any position other than “P” or “R”
for these sensors to operate, however the obstacle at an angle
to the front of the vehicle will also be detected while the selector
lever is in “R”.
CAUTION
With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is changed;
from certain avoidance to unavoidable collision; and
there are also times when
the decision will be changed
from avoidance if steering is changed, to certain
collision. When you move your vehicle, be sure to
confirm a safe distance around your vehicle with your
eyes and drive slowly, or an accident or injury may
result.
The steering guidance may not operate properly in the
following conditions:
Tires other than those of Lexus genuine size are
installed.
The steering sensor information cannot be received
properly. (See “Intuitive parking assist failure warning”
on page 385.) (A) Collision will be unavoidable

The indicator bars will come on depending on the
distance to the obstacle.

The indicator bars will come on in green depending on the
distance to the obstacle. In addition, the current direction
of the tires is also indicated in 3 stages.
Beeps:
Beeps will not sound.
CAUTION
To avoid an accident or injury, observe the following.
When you move your vehicle, be sure to confirm a safe
distance around your vehicle with your eyes and drive
slowly.
With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is
changed; from certain avoidance to unavoidable
collision; and there are also times when the decision
will be changed from avoidance if steering is
changed, to certain collision.
When an obstacle is detected within about 25 cm (0.8
ft.) from the vehicle, the dual sensors will change the
determination to an unavoidable collision.

When the intuitive parking assist determines that the
collision will be unavoidable:
The indicator will flash yellow depending on the distance to the
obstacle. When the distance between the vehicle and the
obstacle is less than about 25 cm (0.8 ft.), the yellow indicator
will turn red.
When the intuitive parking assist determines that the
collision will be avoided by changing the steering:
The indicator will flash yellow depending on the distance to the
vehicle. The steering guide symbol and arrow do not appear. When the intuitive parking assist determines that the
collision will be avoided with the present steering angle:
The indicator will come on in green.
However, if the sensors detect and determine an obstacle at
an angle to the front of the vehicle, the indicator will not come
on.
Beeps (except for avoidable collisions at the present
steering angle):
As distance to the obstacle gets closer, the interval of the
intermittent
sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).
CAUTION
When an obstacle is detected within about 25 cm (0.8
ft.) from the vehicle, the dual sensors will change the
determination to an unavoidable collision.
With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is

collision; and there are also times when the decision
will be changed from avoidance if steering is
changed, to certain collision.

STARTING AND DRIVING
409
After bringing the vehicle to
the desired speed, press the
control lever downward in the “– SET” direction and release it.
This sets the vehicle at that speed. At this time, the
multi−information display indicates settings such as the preset
vehicle speed, whether a vehicle is present ahead and
selected vehicle −to−vehicle distance. If there is no vehicle
detected ahead, the dynamic radar cruise control screen does
not display the vehicle ahead. At this time, you may take your
foot off the accelerator pedal. If you need to accelerate − for
example, when passing − depress the accelerator pedal
enough for the vehicle to exceed the preset speed. When you
release the accelerator pedal, the vehicle will return to the
control prior to acceleration.
You cannot set a desired speed if the master warning light
comes on, the warning tone sounds and the multi− information
display indicates a warning message such as “CRUISE NOT
AVAILABLE”, “CLEAN RADAR SENSOR” or “CHECK
CRUISE SYSTEM”. If any of the above messages appears on
the display, see “Vehicle −to−vehicle distance control mode
failure warning” on page 417.
If you turn off the “ON−OFF” button while the warning message
is displayed, the warning message turns off and the
multi−information display switches to another screen. If no
warning message appears on the display, when you turn the
“ON−OFF” button on again, the setting can be made.
You can change the dynamic radar cruise control screen to
another screen even while the warning message is displayed.
2 Cancelling the preset speed
You can cancel the preset speed by doing any of the following:
a. Pulling the control lever, in the ”CANCEL” direction.
b. Depressing the brake pedal.
c. Pushing the “ON− OFF” button.
If cancelled by a. or b., the multi−information display shows
“RADAR READY” and the dynamic radar cruise control enters
the ready mode.
If cancelled by c., the “CRUISE” indicator light goes off in the
instrument cluster and the multi −information display shows
“CRUISE OFF”. In this case, the preset speed data is cleared,
and you must set the speed from the beginning.
In the following case, the preset speed automatically
cancels out. At this time, the multi information display
shows “RADAR READY” and the dynamic radar cruise
control enters the ready mode.
The vehicle speed falls below about 40 km/h (25 mph). (40
km/h (25 mph) is designated as a cancel speed.)
CAUTION
In this case, the warning tone reminds you that the
dynamic radar cruise control is cancelled and you must
apply the brakes to slow the vehicle.
