■“Brake more” warning
The “brake more” warning is activated while Adaptive Cruise Control is tracking a lead
vehicle. This function warns the driver when it determines that the current level of
deceleration by automatic braking control is insufficient.
x When the ‘brake more’ function operates,
“Obstacle Detected” will be shown in the
warning screen area of the multi information
display, a lead vehicle indicator will flash,
and a buzzer will sound several short
beeps.
x When this function activates, depress the
brake pedal to decelerate and maintain a
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 intersection 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 obsta-
cle and react to it.

- Roads with sharp curves
- Roads with lane restric- tions or tentative lanes due
to construction work, etc.
- Old lane markings remain.
- Snow, puddles or snow melting agents remain on

- Frozen roads, snow-covered roads or other slippery road surfacesThe tires may spin, causing loss of control of the vehicle.
- When entering a sharp curve into an interchange or junction, or a service area, parking area, toll booth or other facilities.
- When there are changes in brightness, such as at a tunnel entrance or exit.
- When visibility is poor due to sand, smoke or water vapor blowing in the wind, or when the vehicle in front or oncoming traffic causes water,
snow, dirt or dust to obscure the view.
- When there is snow, frost, dirt or dust on the windshield or it is clouded.
- When water droplets from rain or dirt have not been fully wiped off on the windshield.
It may not be possible to detect the lane, making correct control impossi-
ble.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle).

- When a vehicle intruded from an adjacent lane or the vehicle in front changed lanes.
- The shape of a curve in the road suddenly changes.
- Shadows of guardrails or similar objects are overlapped on the lane markings.
- When your vehicle is exposed to a strong light from the front (backlight from the sun, headlights, etc.).
- The width of a lane is narrow.
- The stereo cameras may have difficulty detecting the lane due to the per- formance of the cameras.
• There are no lane markings or they are very worn.
• The lane markings are painted in yellow.

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.
