Adaptive Cruise Control
37
CAUTION
xAfter Adaptive Cruise Control has started, it maintains control continuously
according to the behavior of the vehicle in front. When your vehicle comes
to a stop if the vehicle in front has stopped, the stay-stopped function is
engaged. However, if the EyeSight stereo cameras lost detection of the
vehicle in front, the system may not stop your vehicle. Operate the brake
pedal and maintain the correct following distance as necessary. Be aware
that the EyeSight system has difficulty detecting objects or vehicles that
have a relative speed in comparison to your vehicle. Therefore, if the
EyeSight system loses detection just as you are approaching a line of
stopped cars, for example - you will have to brake manually.
xThere is no possibility that the vehicle will automatically begin moving from
a stay-stopped condition without operation from the driver.
xIf the conditions for automatically canceling cruise control (
Ÿ refer to page
49) are met while the vehicle is stay-stopped, Adaptive Cruise Control is
canceled and for safety reasons, the electronic parking brake is automati-
cally applied.
xBraking may not be sufficient depending on the following conditions. Oper-
ate the brake pedal and decelerate as necessary.
- Vehicle conditions (amount of load, number of occupants, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- Vehicle maintenance status (brake systems, tire wear, air pressure, tem-
porary spare tire is being used, etc.)
- When the brakes are cold. (For example, just after the engine is started
or when the outside temperature is low.)
- For a short period of time when driving after the engine is started until the
engine has warmed-up
- When the brakes are overheated on downhill grades (braking effective-
ness may be reduced)
- When driving in rain or after washing the vehicle (the brakes may
become wet and braking effectiveness may be reduced)
- When towing a trailer or another vehicle, etc.

(2) Setting Adaptive Cruise Control
Press the RES/SET switch to the “SET/-”.
Adaptive Cruise Control is now set, and cruise
control will start.
If no vehicle in front has been detected, the
vehicle drives at the constant set target
speed.
When Adaptive Cruise Control is set, the set
speed and are displayed on the EyeSight
display area.
NOTE
xThe target vehicle speed can be set between 25 MPH (40 km/h) and 90
MPH (145 km/h).
xIf the vehicle speed is approximately 25 MPH (40 km/h) or less when the
vehicle speed is set, the set vehicle speed is set to 25 MPH (40 km/h).
xWhen driving on a curve, the vehicle may not accelerate, or may deceler-
ate, even if the set speed is higher than the current vehicle speed.

When a vehicle in front is detected, a buzzer
sounds 1 short beep and the lead vehicle indi-
cator will illuminate. (white) will turn
green.
The vehicle tracks the lead vehicle in front
and maintains the selected following distance.
At this time, the speed upper limit is the set
vehicle speed. If the vehicle in front is no lon-
ger detected, a buzzer sounds 1 short beep
and the lead vehicle indicator turns off.
(green) will turn white.
Operation of Adaptive Cruise Control
xWhen no vehicle in front is detected
The vehicle drives constantly at the set tar-
get vehicle speed between approximately
25 MPH (40 km/h) and 90 MPH (145 km/h).
xWhen a vehicle in front is detected
The vehicle tracks the lead vehicle in front,
and will maintain the chosen following dis-
tance (there are four settings), up to the set
target vehicle speed - between 25 MPH (40
km/h) and 90 MPH (145 km/h).
NOTE
The buzzer sound (lead vehicle acquisition sound) that occurs when a vehicle
in front is detected or no longer detected while Adaptive Cruise Control is set
can be turned off by customization.
Ÿ Refer to page 89.

xIf your vehicle no longer detects the vehicle
in front
The vehicle gradually accelerates back to
the set target vehicle speed and will drive at
that constant speed.
If a vehicle in front is detected while accel-
erating to the set target vehicle speed, vehi-
cle tracking will be started again.
CAUTION
If the driver operates the brake pedal during automatic braking, the pedal
may feel stiff; however, this is not a malfunction. By depressing the brake
pedal further you can apply more braking force. When the brake pedal is
released it will return to its original condition.
NOTE
xWhen the brakes are applied by Adaptive Cruise Control, the vehicle’s
brake lights will illuminate.
xEven if there is no lead vehicle present, on a downhill grade, the Adaptive
Cruise Control’s automatic brake may operate in order to maintain the set
target vehicle speed.
xSome noises may be audible during automatic braking. This is caused by
the braking control and does not indicate a malfunction.
xTo temporarily accelerate quickly, use the accelerator pedal. After acceler-
ating, the vehicle will gradually return to the set target vehicle speed shown
in the gauge cluster.
xThere are cases where the vehicle in front has turned off the road while
your vehicle is still controlled by the automatic braking operation that has
activated due to the deceleration of the vehicle in front of yours. In those
cases, the brake will be automatically released gradually. Depress the
accelerator pedal if necessary.
xThe lead-vehicle tracking function has the following characteristics:
- If the lead vehicle’s brake lamp is detected, deceleration is started more
quickly than without detection.
- If the vehicle moves to the fast lane while travelling more than 37 MPH
(60 km/h), the system starts acceleration to the set vehicle speed more
quickly because it is linked with the turn signal.

■Increasing the set vehicle target speed
●
Using the RES/SET switch
Push the RES/SET switch in the following
way while you are driving with Adaptive
Cruise Control on:
xPush the RES/+ switch towards the position
(1) briefly: the set vehicle speed will
increase in increments of 1 MPH (1 km/h)
every time the button is pushed.
xPush the RES/+ switch towards the position
(1) for longer: the set vehicle speed will
increase in increments of 1 MPH (1 km/h)
while the button is being pushed.
xPush the RES/+ switch towards the position (2) briefly: the set vehicle speed will increase
to the next 5 MPH (5 km/h) increment every time the button is pushed.
xPush the RES/+ switch towards the position (2) for longer: the set vehicle speed will increase
to the next 5 MPH (5 km/h) increment while the button is being pushed and will continue to
advance target speed in 5 MPH (5 km/h) increments as long as the button is pushed.
The set vehicle target speed is shown on the EyeSight display. Using this method, you can
‘fine tune’ the vehicle’s set target speed.
●Using the accelerator pedal
Depressing the accelerator pedal will increase vehicle speed. Once the preferred speed has
been attained, push the RES/SET switch to SET/-. When the switch is pressed, the new
vehicle target speed will be set. The new set vehicle speed will be displayed in the EyeSight
display area.
CAUTION
xWhen Adaptive Cruise Control is operating, the actual vehicle speed is
controlled according to the lead vehicle. Therefore, if the RES/SET switch
is pressed to the “RES/+” and set to a speed higher than the speed of the
lead vehicle, the vehicle will not accelerate - it will maintain a safe following
distance as the first priority. However, because doing so changed the set
vehicle target speed, when the lead vehicle is no longer detected (for
example, if you change to a freeway lane with no vehicles in front), the
vehicle will accelerate to that new set target speed. Change the set vehicle
target speed while briefly checking the value shown in the set speed dis-
play on the EyeSight display.
xWhen the accelerator pedal is depressed with Adaptive Cruise Control on,
automatic braking control and warnings by Adaptive Cruise Control will not
occur. However, if there is a high risk of collision with an obstacle in front of
the vehicle at this time, the warning and braking control of the Pre-Collision
Braking System may activate.

■Decreasing the set vehicle target speed
●
Using the RES/SET switch
Push the RES/SET switch in the following
way while you are driving with Adaptive
Cruise Control on:
xPush the SET/- switch towards the position
(1) briefly: the set vehicle speed will
decrease in increments of 1 MPH (1 km/h)
every time the button is pushed.
xPush the SET/- switch towards the position
(1) for longer: the set vehicle speed will
decrease in increments of 1 MPH (1 km/h)
while the button is being pushed.
xPush the SET/- switch towards the position (2) briefly: the set vehicle speed will decrease
to the next 5 MPH (5 km/h) decrement every time the button is pushed.
xPush the SET/- switch towards the position (2) for longer: the set vehicle speed will
decrease to the next 5 MPH (5 km/h) decrement while the button is being pushed and will
continue to lower target speed in 5 MPH (5 km/h) decrements as long as the button is
pushed.
The set vehicle target speed is shown on the EyeSight display.
●Using the brake pedal
(1) Depress the brake pedal to decrease the vehicle speed. (Adaptive Cruise Control will be
canceled and will be turned off.)
(2) When the desired speed is reached, press the RES/SET switch to the “SET/-”. The
speed at the time of pressing the switch will be set as the new vehicle speed, and it
appears in the EyeSight display area.
■Accelerating temporarily
Depress the accelerator pedal to accelerate temporarily.
When the accelerator pedal is released, the vehicle returns to the set vehicle speed.

■Decelerating temporarily
Depress the brake pedal to decelerate tempo-
rarily. When the brake pedal is depressed,
Adaptive Cruise Control will be canceled. The
will be turned off while the set vehicle tar-
get speed remains displayed on the EyeSight
display area.
Release the brake pedal and press the
RES/SET switch to “RES/+” to reset the set
vehicle target speed.
CAUTION
Ordinarily, while Adaptive Cruise Control is functioning, acceleration and
deceleration are performed automatically according to the speed of the lead
vehicle (if one is detected). However, when your vehicle approaches a lead
vehicle, for example if it is necessary to accelerate for a lane change or other
reason, and if the vehicle in front suddenly decelerates, or if another vehicle
cuts into your path, operate the accelerator pedal or brake pedal and acceler-
ate or decelerate as appropriate for the existing conditions.

■Stay-stopped function
If the vehicle in front comes to a stop while you are utilizing Adaptive Cruise Control, your
vehicle will also come to a stop and will stay stopped.
When your vehicle comes to stop after the vehicle in front has stopped, Adaptive Cruise
Control is paused and the stay-stopped function is engaged. on the EyeSight display
area is turned off and is displayed. At the same time, is turned back to white.
●Resuming Adaptive Cruise Control in stay-stopped status
▼Setting using the RES/SET switch
Press “SET/-” (Ÿ Refer to page 39 “(2) Setting Adaptive Cruise Control”.)
Press “RES/+” (
Ÿ Refer to page 51 “Returning to a vehicle speed that was previously
set”.)
▼Setting with the accelerator pedal
Depressing the accelerator pedal while stay-stopped is engaged cancels stay-stopped
status. At this time, Adaptive Cruise Control is resumed. The vehicle will attempt to travel
at the previously set vehicle target speed unless a lead vehicle is detected. If a lead vehi-
cle is detected, Adaptive Cruise Control will maintain the previous following distance set-
ting.
NOTE
When Adaptive Cruise Control is resumed from stay-stopped status and the
vehicle in front accelerates, your vehicle will also accelerate and continue to
track the vehicle in front at the previously set following distance. However, if
the lead vehicle does not start moving or pauses, stay-stopped status will be
automatically restored after approximately 3 seconds.
NOTE
If the accelerator pedal is only slightly depressed, the stay-stopped function
may not be canceled, and the Adaptive Cruise Control may not be resumed.
