■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: x Push 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.
x Push 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.
x Push 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.
x Push 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
x When Adaptive Cruise Control is operating, the actual vehicle speed is
controlled according to the lead vehicl e. 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.
x When 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: x Push 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.
x Push 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.
x Push 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.
x Push 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.

■Changing the following distance from the vehicle in front
The following distance from the vehicle in front setting can be changed in 4 stages.
: When the switch ( side) is pressed, the following distance will be longer.
: When the switch ( side) is pressed, the following distance will be shorter.
NOTE
xThe following distance changes according to the vehicle speed and
increases the faster the vehicle travels.

xIf you turn the (CRUISE) switch off, and then turn it on again, the fol-
lowing distance that was set before you turned the switch off will be main-
tained.

■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
T 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”.)
T 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.
