Cruising in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles
within 400 ft. (120 m) ahead and to judge the distance between your
vehicle and those vehicles.
Note that vehicle-to-vehicle distance will close when traveling on long down -
hill slopes.
Example of constant speed cruising (when there are no vehicles
ahead): When set to 62 mph (100 km/h)
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehi-
cle distance can also be set by oper ating the v
ehicle-to-vehicle distance
switch.
Example of deceleration cruising (wh en the vehicle ahead is driving
slower than the set speed): When fixed speed cruising is set at 6
2 mph
(100 km/h) and the vehicle ahead is driving at 50 mph (80 km/h)
When a vehicle is detected running ahead of you, in the same lane, the sys -
tem automatically decelerates your vehicle. When a greater reduction in
v
ehicle speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing on the vehicle ahead.

When driving
Example of follow-up cruising (when following a vehicle driving slower
than the set speed): When the speed is set to 62 mph (100 km/h) and
the v
ehicle ahead is driving at 50 mph (80 km/h)
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis -
tance set by the driver.
Example of acceleration (when ther e are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
6
2 mph (100 km/h) and the vehicle ahead driving at 50 mph (80 km/
h) is out of the lane
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
■Dynamic radar cruise control warning lights, messages and buzzers
Warning lights, messages and buzzers are us ed to in
dicate a system malfunction or
to alert you to the need for caution while driving. ( P. 4 5 8 )
■The dynamic radar cruise can be set when
●The shift lever is in “D” or the “4”, “5” or “6” range of “S”.
●Vehicle speed is between approximately 27 mph (43 km/h) and 87 mph (139
km/h).
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed
r

esumes.

■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice or plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
FCC RF exposure information

Intuitive parking assist (if equipped)
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the mult i-information display, the touch screen,
and warning beeps.

The system may be used at speeds less than about 6 mph (10 km/h).
■ Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, an d one in each corner of the bumper,
to detect obstacles in those areas. 
The dual sensors detect obstacles ahea d of the v
ehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. (25 cm) of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.

Display distance and beeps
When the intuitive parking assist is activated, the approximate distance to
the obstacle is displayed. Also, if an obstacle with which a collision is pos-
sible is detected, a warning beep will sound.

• If the shift lever is in “R”, only th e corner sensors will detect obstacles.

Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves closer to the obstacle, the interval of
the beep becomes shorter.
● When the follo
wing obstacle distan ces are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1 f
t. (35 cm).
●If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obst acles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.
● If multiple obstacles ar
e detected in front and behind th e vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of th e vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0
.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn -
ing beeps will sound 2 beeps then one continuous beep
.
●You can change the volume of the warning beeps. ( P. 1 5 0 )

When driving
If the steering information is not being correctly received
If the system is unable to receive signals from the steering sensor, or there
is a malfunction in the VGRS, the steer ing guide symbol and both arrows
will flash if the dual sensors detect an obstacle. 
In this case, have the vehicle checked by your Lexus dealer.
Multi-information display
Touch screen
If the steering guide symbol is on or flashing, the intuitiv
e parking assist
maximum detection range is reduced from 3.0 ft. (100 cm) to 1.5 ft. (50
cm). 
The steering sensor malfunction warnin g display will be aligned with the
intuitiv
e parking assist detection displa y or the intuitive parking assist mal -
function warning display.
