behind an obstacle
x When there is a vehicle, motorcycle, bicycle or pedestrian in a location
close to your vehicle’s bumper
x When the speed difference between your vehicle and an obstacle is 4
MPH (5 km/h) or less (As braking is performed once the obstacle is in
close proximity to your vehicle, depending on the shape and size of the
obstacle, there may be some cases when the obstacle is outside the
range of the cameras’ field of view.)
x When driving on sharp curves, steep uphill grades or steep downhill
grades
x When driving on a bumpy or unpaved road
x When there are changes in brightness, such as at a tunnel entrance or
exit

Pre-Collision Braking System
27
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the multi information display illuminate to warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the multi information display illu-
minate to warn the driver, and braking control is activated and the engine output, in some
situations, is also controlled. If the system determines that the amount of evasive action
(braking, steering, etc.) taken by the driver has reduced the risk of collision, braking activa-
tion is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control and the engine output control are continued.
Even after the vehicle has stopped, depress the brake pedal.

Until the brake pedal is depressed, a mes-
sage appears and stays in the warning screen
area of the multi information display for
approximately 2 minutes. A single continuous
beep sounds while the message is displayed.

Pre-Collision Braking System
29
When the Pre-Collision Braking System is activated (when the system determines that there
is a high risk of collision with an obstacle in front), if the driver depresses the brake pedal,
the system determines that this is emergency braking and activates braking assist automat-
ically.x
Neither first braking or secondary braking will operate in the following
cases.
- When the vehicle is traveling at approximately 1 MPH (1 km/h) or less (When the select lever is in the position and your vehicle speed is
approximately 2 MPH (4 km/h) or less) or 100 MPH (160 km/h) or more
- When Vehicle Dynamics Control is active
x If the system detects the brake lights of the vehicle in front, your vehicle
will start decelerating earlier than if it does not.
x There are some cases where the first braking is applied for a longer period
of time. One of the reasons for this is due to a large speed difference with
an obstacle in front. In those cases, stronger or weaker braking control
may be activated.
Pre-Collision Braking Assist operation
CAUTION
If the driver depresses the brake pedal manually while following distance
warning is activated, the Pre-Collision Braking Assist will not work. (The vehi-
cle decelerates with the normal braking force operated by the driver.)
NOTE
xPre-Collision Braking Assist function does not operate when the vehicle
speed is approximately 7 MPH (10 km/h) or less or 100 MPH (160 km/h) or
more.
x For information about the braking assist function, refer to the Owner’s
Manual for your vehicle.

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. Through operation of the electronic parking brake,
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
xThis 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 prevent rear-end collisions.
Strive for safe driving at all times. Always maintain a safe following distance
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 neces-
sary.
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.

Troubleshooting
95
EyeSight does not restart after a temporary stop.
Is the X-mode turned on?
EyeSight cannot be activated when the X-mode is turned on.
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.
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.
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.
