Adaptive Cruise Control
Adaptive Cruise Control is a driving support system intended to allow more comfortable
driving on expressways, freeways and interstate highways. The vehicle in front in the same
traffic lane is detected by means of the stereo cameras, and your vehicle tracks the vehicle
in front (up to the maximum speed of the set vehicle speed) while automatically maintaining
a following distance that corresponds to the speed of the vehicle in front. The system uses
the vehicle’s conventional braking system to stop your vehicle when the vehicle in front is
stopped. The vehicle is capable of being controlled at a speed between approximately 0 and
90 MPH (145 km/h). Please remember that you should not exceed posted speed limits.
WARNING
x This system does not provide the driver with an automatic driving function
that handles all traffic conditions.
x Do not rely excessively on Adaptive Cruise Control. This system is not
intended to assist in driving when the driver is not paying full attention to
what is ahead of him/her due to distractions or a lack of concentration
while driving, or under conditions of poor visibility. It is not intended to pre-
vent rear-end collisions.
Strive for safe driving at all times. Always maintain a safe following dis-
tance behind the vehicle in front of you, pay attention to your surroundings
and the driving conditions, and operate the brake pedal and take other
action as necessary.
x Set the set vehicle speed within a range that is appropriate to the road con-
ditions and surrounding environment.
x Before using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
Ÿ Refer to the separate “Warranty and Maintenance Booklet”.
x The system may not operate correctly under the conditions listed below.
When these conditions occur, do not use Adaptive Cruise Control.
- The tire pressure is not correct.

- 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
control 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)• An empty truck or trailer that has no cargo in the
cargo bed being affected
by wind
• Vehicles that have cargo protruding from their
back ends
• Non-standard shaped ve- hicles (vehicle transport-
ers or vehicles with a sidecar fitted, etc.)
• 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.

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
accelerating to the set target vehicle speed,
vehicle 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.

Pre-Collision Throttle Management
63
Continued on next page Ÿ
x
If your vehicle is trapped on a railroad crossing and you are trying to
escape by driving through the crossing gate, the stereo cameras may rec-
ognize the crossing gate as an obstacle and Pre-Collision Throttle
Management system may activate. In this case, remain calm and either
continue to depress the accelerator pedal or turn off the Pre-Collision
Throttle Management system.
Ÿ Refer to page 67.
x Pre-Collision Throttle Management may not activate depending on the fol-
lowing conditions:
- The distance between your vehicle and the obstacle, speed difference, and lateral displacement (amount of offset)
- Recognition status of the stereo cameras
In particular, the function may not activate in the following cases:• Bad weather (for example heavy rain, a blizzard or thick fog)
• When visibility is poor due to sand or smoke in the air
• When light is poor in the evening, early morning, or at night
• In a dark area (indoor parking area, etc.)
• When there is an obstacle outside the area illuminated by the head-
lights
• When affected by strong light from the front (for example sunlight at sunrise or sunset headlight beams, etc.)
• When there is snow, frost, dirt or dust on the windshield, or it is clouded
• When fluid has not been fully wiped off the windshield during or after use of the window washer
• When obstacles cannot be correctly recognized due to water droplets from rain or the washer, or the wiper blades obstructing the stereo cam-
eras’ field of view
• When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)
• With low obstacles (low wall, crash barrier, low vehicle, etc.)
• When the size and height of an obstacle is smaller than the limitations of the stereo cameras’ recognition capability
• With small animals or children.
• With pedestrians who are sitting or lying down
• When the rear portion
nearest your vehicle is
too small or too close
(such as a trailer or
oncoming vehicle) the
system may not recog-
nize the part of that
vehicle which is closest
to you.

Lane Sway Warning
71
Lane Sway Warning
This function detects wandering or drifting within a lane, and warns the driver. When the
Lane Sway Warning activates, a buzzer sounds 6 short beeps, the steering wheel indicator
light blinks and the lane indicator lights on the multi information display blink alternately left
and right.
This function activates only when the vehicle speed is approximately 38 MPH (60 km/h) or
more.
WARNING
Lane Sway Warning will not operate in all conditions. It also will not automati-
cally correct wandering. If the driver relies only on the Lane Sway Warning to
prevent the vehicle from wandering, an accident may occur.
CAUTION
Under the following conditions, the Lane Sway Warning may not operate.x When driving on a winding road
x When vehicle speed changes greatly
x Immediately after a lane change
x When it is difficult for the EyeSight stereo cameras to detect lane markings
- There are no lane markings or they are the very worn.
- It is difficult to detect lane markings as they are similar in color to the road surface.
- The lane markings are narrow.

Troubleshooting
98
EyeSight does not restart after a temporary stop.
Has the vehicle been parked in a cold or hot place? In either of these cases,
EyeSight may temporarily stop operating until the temperature increases or
decreases to a temperature at which the camera is operable.
Are you driving in the rain with old wipers or is there an oily film on the windshield?
Replace the wipers with new ones, or clean the oily film off the windshield.
Are you driving in poor weather conditions with heavy rain, snow, fog, or dust? In
these cases, EyeSight may temporarily stop operating while visibility is very low.
Is your vehicle subject to sunlight from the front (sunset or sunrise, etc.) or to
bright headlights from oncoming vehicles at nighttime?
In these cases, EyeSight may temporarily stop operating.
The timing of the “brake more” warning is sometimes earlier and sometimes later
than what seems to be normal operation.
The “brake more” warning sounds when the system determines that more braking
is necessary, based on conditions such as the distance from the vehicle in front
and the difference in speed compared to it. As a result, timing may vary depend-
ing on how the brakes are applied in relation to the vehicle in front, and your rela-
tive speed to that vehicle.
When the vehicle in front has turned off the road away or the distance from the
vehicle in front has increased, acceleration is sometimes slower or faster.
Depending on the timing of when the detection of the vehicle in front is lost,
EyeSight’s ability to react may be slower, causing the start of acceleration to feel
delayed and braking time to feel longer than what seems to be normal operation.
