When constant speed control mode is selected, your vehicle will maintain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicle-to-vehicle distance control mode does not function correctly due to a dirty radar, etc.
1. With the cruise control off, press and hold the cruise control main switch for 1.5 seconds or more.
Immediately after the switch is pressed, the dynamic radar cruise control indicator will come on.
Afterwards, it switches to the cruise control indicator.
Switching to constant speed control mode is only possible when operating the switch with the cruise control off.
2. Accelerate or decelerate, with accelerator pedal operation, to the desired vehicle speed (at or above approximately 20 mph [30 km/h] ) and press the "- SET" switch to set the speed.
Cruise control "SET" indicator will come on.
The vehicle speed at the moment the switch is released becomes the set speed.
■Dynamic radar cruise control with full-speed range can be set when
(However, when the vehicle speed is set while driving at below approximately 20 mph [30 km/h], the set speed will be set to approximately 20 mph [30 km/h].)
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease below the set speed in order to maintain the distance to the preceding vehicle.
■When the vehicle stops while follow-up cruising
■Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situations:
If vehicle-to-vehicle distance control mode is automatically canceled for any reasons other than the above, there may be a malfunction in the system.
Contact your Toyota dealer.
■Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situations:
If constant speed control mode is automatically canceled for any reasons other than the above, there may be a malfunction in the system. Contact your Toyota dealer.
■Situations in which the curve speed reduction function may not operate
In situations such as the following, the curve speed reduction function may not operate:
A brake operation sound may be heard and the brake pedal response may change, but these are not malfunctions.
■Warning messages and buzzers for dynamic radar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driving. If a warning message is shown on the multi-information display, read the message and follow the instructions.
■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach warning may not be activated.
■Conditions under which the vehicle-to-vehicle distance control mode may not function correctly
In the case of the following conditions, operate the brake pedal (or accelerator pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not operate properly.
■Situations in which the curve speed reduction function may not operate properly
In situations such as the following, the curve speed reduction function may not operate properly:
