■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.
●Vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown correspond
to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance increases/
decreases in accordance with vehicle speed.
■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 and plas-
tic objects, cannot be detected by the obstruction sensor.) 
Dynamic radar cruise control is canceled if an obstruction is detected.
■Warning lights, messages and buzzer for dynamic radar cruise control
Warning lights, messages and buzzer ar e used to indicate a system malfunc-
tion or to inform the driver of th e need for caution while driving. ( P. 6 9 8 )

■When the vehicle has been parked in the sun
The LDA system may not be available for a while after driving has started. In such
cases, turn the LDA system off and turn it on again after normal temperature
returns. When the temperature in the cab in decreases and the temperature around
the camera sensor becomes suitable for it s operation, the functions will begin to
operate.
■Warning lights and messages for LDA
Warning lights and messages ar e used to indicate a system malfunction or to inform
the driver of the need for caution while driving. ( P. 6 9 8 )
CAUTION
■Before using the LDA system
This system provides information to the driver in accordance with the road geome-
try and the driving conditions. Be aware of your surroundings at all times, correct
the driving path while driving appropriately and be responsible for your own safety.
This system operates by using the camera to identify lane markers when the LDA
switch is on and the vehicle is being driven at the system operating speed. 
Operation may be temporarily suspended if the camera cannot recognize the lane
markers or if the system cannot operate due to the road environment or driving
conditions. Also, since an alarm may sound unnecessarily if the lane markers cannot
be correctly identified, make sure to drive responsibly even while the system is
operating.
If a malfunction occurs in the system, the driver will be alerted by a buzzer and a dis-
play, and LDA operation will be temporarily suspended. However, this does not
present a problem to normal driving.
If the alert is displayed even after restarti ng the engine, have your vehicle inspected
by your Lexus dealer.
