■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.

●Canceling the stay-stopped function
If any of the following operations is performed, the stay-stopped function will be canceled
and the Adaptive Cruise Control will be canceled at the same time.
x The brake pedal is depressed.
x The (CRUISE) switch is pressed.
x The electronic parking brake switch is pressed to apply the Electronic Parking Brake.
●Setting Adaptive Cruise Control while the Electronic Parking Brake is applied
If the Electronic Parking Brake is applied, then before setting cruise control, release the
Electronic Parking Brake by depressing the accelerator pedal or by other specified
means. For details of how to release the electronic parking brake, refer to the Owner’s
Manual for your vehicle.
WARNING
xWhile the stay-stopped function is engaged, do not exit the vehicle.
x The stay-stopped function is not a replacement for engaging the parking
brake.
When parking, always apply brakes manually to come to a full stop, then
set the electronic parking brake.
CAUTION
The stay-stopped function of cruise control will be canceled under the follow-
ing conditions:
x The vehicle is in stay-stopped mode for approximately 2 minutes or more.
(A buzzer will sound 5 intermittent beeps and 1 long beep.)
x Any condition in which automatic cancellation is met. (A buzzer sounds 1
long beep.)
Ÿ Refer to page 49.
After the stay-stopped function has been canceled, the Electronic Parking
Brake will be automatically applied and the electronic parking brake indicator
light will illuminate. However, if any canceling condition for the Electronic
Parking Brake (i.e. the interlock system with the accelerator pedal, switch
operation of the electronic parking brake, etc.) is fulfilled, the Electronic Park-
ing Brake will not work. (For details, refer to the Owner’s Manual for your
vehicle.)
If the accelerator pedal is only slightly depressed while the stay-stopped func-
tion is activated, the stay-stopped function of cruise control may be canceled,
and the Electronic Parking Brake may not work.

WARNING
Do not use Adaptive Cruise Control on slippery roads. Doing so may result in
an accident.
CAUTION
When shifting the select lever to the position, Adaptive Cruise Control will
be automatically canceled. Do not shift the lever to the position unless it is
an emergency. Otherwise the engine brake may not operate, which could
cause an accident.
NOTE
xIf EyeSight operation has temporarily stopped, the Pre-Collision Braking
System OFF indicator light and Lane Departure Warning OFF indicator
light illuminate, and the EyeSight temporary stop indicator is displayed on
the multi information display.

WARNING
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.
x The “brake more” warning will not activate in the following situations.
- The accelerator pedal is depressed.
- The brake pedal is depressed.
x Even when the following distance is short, the “brake more” warning may
not activate in the following situations.
- The difference in speed with the vehicle in front is small. (The two vehi- cles are traveling at almost the same speed.)
- The vehicle in front is traveling faster than your vehicle. (The following distance is gradually increasing.)
- Another vehicle cuts into your lane very close to your vehicle.
- The vehicle in front decelerates suddenly.
- When there are repeated uphill and downhill grades
x The “brake more” warning may not activate in time in the case of a vehicle
that is stopped at the end of a line at a toll gate, at a stop light or intersec-
tion or in traffic congestion, or a vehicle that is moving much slower than
your vehicle. EyeSight requires a speed differential in order to recognize a
potential obstacle and react to it.
