ŸContinued from previous page
- 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)
xThe 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
xVehicles that have cargo
protruding from their
back ends
xNon-standard shaped ve- hicles (vehicle transporters or vehicles with a
sidecar fitted, etc.)
xVehicles that are low
- Objects that are located close to the bumper of your vehicle
xWhen 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.
xBefore 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.

Detection of the vehicle in front by the EyeSight stereo cameras
xUnder the following road conditions or conditions of your vehicle, detection
of the vehicle in front may not be possible. Vehicles in neighboring traffic
lanes or roadside objects may also be incorrectly detected. Under condi-
tions such as these, do not use Adaptive Cruise Control. If cruise control is
currently in use, operate the brake pedal and take other action as neces-
sary.
- When tracking begins from
a short following distance,
such as when the vehicle
in front is a vehicle that cut
into your lane
- When driving on curved
roads, at the start and end
of a curve and on roads
with continuous curves
(These conditions make it
difficult for the system to
detect vehicles because
they are outside the
detectable area.)
- When driving on an on-
ramp or off-ramp to a free-
way, highway, or other
restricted access road
(EyeSight Adaptive Cruise Control is not designed for use in this kind of
driving environment.)
- When driving in an urban, or suburban environment (Adaptive Cruise
Control is not appropriate for use in these driving areas. Adaptive Cruise
Control should only be used on limited-access highways.)

- When the vehicle in front is
not directly ahead of your
vehicle and is shifted to
one side
- When there is an obstacle
at the side of the road
- When the relative speed
difference compared to the
vehicle in front is large
- When a vehicle cuts into
your lane in front of you
- When the distance between
vehicles is extremely short
- When your vehicle is drift-
ing within the lane
- When driving on a bumpy
or unpaved road surface
- When driving on a road
with extremely narrow lanes, such as when traffic restrictions are in
effect or in areas where construction work is taking place
- When normal driving has become compromised due to an accident or
malfunction
- When extremely heavy cargo is loaded in the cargo area, rear seat or
trunk of your vehicle
xThere are limits to the capabilities of Adaptive Cruise Control. Even when
the vehicle in front is detected, the system may not be able to decelerate in
time in cases such as when the difference in speeds is large or when the
vehicle in front decelerates suddenly. Operate the brake pedal and decel-
erate as necessary.
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.
xEven when the following distance is short, the “brake more” warning may
not activate in the following cases.
- When the relative speed difference compared to the vehicle in front is
small (the two vehicles are travelling at almost the same speed)
- When the vehicle in front is traveling faster than your vehicle (the follow-
ing distance is gradually increasing)
- When another vehicle cuts into your lane very close to your vehicle
- When the vehicle in front decelerated suddenly
- When there are repeated uphill and downhill grades

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.

(1) Setting Adaptive Cruise Control to standby status
Press the (CRUISE) switch. At this time, “ ” (Adaptive Cruise Control), your vehi-
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.

(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.
