1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake
pedal does not cancel the setting.)
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if another driver cuts
in front of you while you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.

■Dynamic radar cruise control with
full-speed range can be set when
●The shift lever is in D.
●The desired set speed can be set
when the vehicle speed is approxi-
mately 30 km/h (20 mph) or more.
(However, when the vehicle speed is set while driving at below approxi-
mately 30 km/h [20 mph], the set
speed will be set to approximately 30
km/h [20 mph].)
■Accelerating after setting the vehi-
cle speed
The vehicle can accelerate by operating
the accelerator pedal. After accelerat-
ing, the set speed resumes. However,
during vehicle-to-vehicle distance con-
trol mode, the vehicle speed may
decrease below the set speed in order
to maintain the distance to the preced-
ing vehicle.
■When the vehicle stops while fol-
low-up cruising
●Pressing the “+RES” switch while the
vehicle ahead stops will resume fol-
low-up cruising if the vehicle ahead
starts off within approximately 3 sec-
onds after the switch is pressed.
●If the vehicle ahead starts off within 3
seconds after your vehicle stops, fol-
low-up cruising will be resumed.
■Automatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control
mode is automatically canceled in the
following situations.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is
turned off.
●The sensor cannot detect correctly
because it is covered in some way.
●When the brake control or output
restriction control of a driving support
system operates.
(For example: Pre-Collision System,
