in vehicle-to-vehicle distance
control mode)
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the lever up or down to change the speed,

starts off, push the lever up.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.
Pulling the lever toward you
cancels 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.)
Pushing the lever up resumes the cruise control and returns vehicle
speed to the set speed.

Driving
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic 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 following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.
QWarnings may not occur when
In the following instances, warnings may not occur even when the
vehicle-to-vehicle distance is small.
OWhen the speed of the preceding vehicle matches or exceeds
your vehicle speed
OWhen the preceding vehicle is traveling at an extremely slow
speed
OImmediately after the cruise control speed was set
OWhen depressing the accelerator pedal

When constant speed control mode is selected, your vehicle will main-
tain 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.
With the cruise control off,

trol mode is only possible when
operating the lever with the cruise
control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 km/h
[20 mph]) and push the lever
down to set the speed.
Cruise control “SET” indicator will

lower than the recognized
speed limit
Push the lever up.
OWhen the current set speed is
higher than the recognized

QDynamic radar cruise control with full-speed range can be set when
OThe shift position is in D.
OThe desired set speed can be set when the vehicle speed is approximately
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].)
QAccelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, 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.
QWhen the vehicle stops while follow-up cruising
OPushing the lever up while the vehicle ahead stops will resume follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.
OIf the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.
QAutomatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
OVSC is activated.
OTRC is activated for a period of time.
OWhen the VSC or TRC system is turned off.
OThe sensor cannot detect correctly because it is covered in some way.
OWhen the brake control or output restriction control of a driving support sys-
tem operates.
(For example: Pre-Collision System, Drive-Start Control)
OThe parking brake is operated.
OThe vehicle is stopped by system control on a steep incline.
OThe following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.
The shift position may automatically change to P. (P. 332)
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.
