2-4. Using other driving systems
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
62 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, display and buzzers
Warning lights, display and buzzers are used to indicate a system malfunction or to
alert you to the need for caution while driving. ( P. 3 3 4 )
■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.
■Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations.
●Vehicle speed falls below 25 mph (40 km/h)
●VSC is activated
●The sensor cannot operate correctly because it is covered in some way.*
●The windshield wipers are operating at high speed.*
●The ECT SNOW switch is set to snow mode.*
*
: Vehicle-to-vehicle distance control driving must be reset by turning the ON-OFF button on again.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

Lexus parking assist-sensor (if equipped)
The distance to obstacles measured by the sensors is communicated via
the multi-information display and a buzzer when parallel parking or
maneuvering into a garage. Always check the surrounding area when
using this system.
For vehicles equipped with a navigation system, refer to the separate “Navi-
gation System Owner’s Manual” for further details.

■ Buzzer operation and distance to the obstacle
A buzzer sounds when the corner se nsors and back sensor are oper-
ating.
● The buzzer beeps faster as the vehicle approaches an obstacle. When the
vehicle comes within the following distance of the obstacle, the buzzer
sounds continuously.
•Corner sensors: 0.8 ft. (25 cm)
• Back sensors: 1.1 ft. (35 cm)
●When two or more obstacles are detected simultaneously, the buzzer sys-
tem responds to the nearest obstacle.

When driving
■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In addition to the examples above, th ere are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
●The shape of the obstacle may prevent th e sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle
