- When water droplets from rain or the window washer, or dirt has not
been fully wiped off the windshield
It may not be possible to detect the vehicle in front, making correct con-
trol impossible.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)
x The stereo cameras may have difficulty detecting the following objects or
conditions. Operate the brake pedal and take other actions as necessary.
- Vehicles at significantly different speeds (vehicles driving slowly, stopped or oncoming vehicles, etc.)
- Vehicles cutting into your lane
- Motorcycles, bicycles, pedestrians and animals, etc.
- When light is poor in the evening or early morning
- When driving at night or in a tunnel without the headlights on
- When driving at night or in a tunnel when there is a vehicle in front that does not have its taillights on
- When affected by strong light from the front (sunlight or headlight high beams, etc.)
- Vehicles in front that have a rear aspect that is low,
small or irregular (the sys-
tem may recognize
another part of the vehicle
and will determine opera-
tion from that)
xAn empty truck or trailer
that has no cargo in the
cargo bed being affected
by wind
x Vehicles that have cargo
protruding from their
back ends
x Non-standard shaped vehicles (vehicle transporters or vehicles with a
sidecar fitted, etc.)
x Vehicles that are low
- Objects that are located close to the bumper of your vehicle
x When you do not want to use Adaptive Cruise Control, be sure to turn the
(CRUISE) switch off. If the switch is left on, cruise control may be
accidentally engaged, possibly resulting in an accident.
x Before using Adaptive Cruise Control, be sure to fully verify the safety of
the vehicle occupants and the area around the vehicle. Never operate the
cruise control from outside the vehicle.

cle indicator and the “following distance setting” are displayed on the EyeSight display area
in the multi information display.
The set vehicle speed display will read “- - MPH”.
If the switch is pressed once more, the EyeSight display will turn off. It will also automatically
turn off when the engine is stopped.
To set ready status: Adaptive Cruise Control can be set when all
of the following conditions are met and
is displayed on the EyeSight display area.
- All doors (except the rear gate/trunk) are closed.

Adaptive Cruise Control

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
x When the brakes are applied by Adaptive Cruise Control, the vehicle’s
brake lights will illuminate.
x Even 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.
x Some noises may be audible during automatic braking. This is caused by
the braking control and does not indicate a malfunction.
x To 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.
x There 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.
x The 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 traveling 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.

■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.

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,

correct following distance.
Other functions
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.
