Adaptive Cruise Control

Continued on next page Ÿ
- 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 speed difference with the vehicle (or object) in front is more
than 20 MPH (30 km/h)
- When a vehicle cuts into your lane in front of you
- When the distance between vehicles is extremely small
- When your vehicle is drifting within the lane
- When driving on a bumpy or unpaved road surface
- When driving on a road with extremely narrow lanes, such as when traf-
fic 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.
xBefore using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
*Refer to the separate “Warranty and Maintenance Booklet”.
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 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 because the vehicle in front has stopped, the automatic braking
function will be cancelled immediately after stopping and the vehicle will
start creeping forward gradually (at the same time three short beeps and a
single long beep will sound). Be sure to depress the brake pedal and stop
the vehicle completely.
Note that the vehicle is not maintained at a standstill position and will not
automatically start moving from a standstill position.
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 the speed to potential obstacles is more than 20 MPH (30 km/h)

- Even if the obstacle is a motorcycle, bicycle or pedestrian, depending on
the brightness of the surroundings as well as the relative movement, and
aspect or angle of the object, there may be cases when the system can-
not detect it.
- When the system determines that operation by the driver (based on
accelerator pedal operation, braking, steering wheel angle, etc.) is
intended as evasive action
- Vehicle maintenance status (brake systems, tire wear, tire pressure,
whether a temporary spare tire is being used, etc.)
- When towing a trailer or vehicle, etc.
- When the brakes are cold due to outside temperature being low or just
after starting the engine.
- When the brakes are overheated on downhill grades (braking effective-
ness is reduced)
- When driving in rain or after washing the vehicle (the brakes are wet and
braking effectiveness is reduced)
- Recognition conditions of the stereo cameras
In particular, the function may be unable to stop the vehicle or 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, smoke or water vapor in the air or
when the vehicle in front or oncoming traffic causes water, snow, dirt,
dust or other substances to obscure the view through the windshield
• 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 approaching a motorcycle, bicycle or pedestrian at night
• When ambient light is poor in the evening or early morning
• When a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
• When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight high 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
washer use
• When the target cannot be correctly recognized because the stereo
cameras’ view is obstructed by water droplets from rain or the window
washer, or by the wiper blades.
• When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
• When the rear aspect of
the vehicle in front is
low, small or irregular
(the system may recog-
nize another part of the
vehicle as its rear and
will determine operation
from that)
- When there is an
empty truck or trailer
with no rear and/or
side panels on the
cargo bed
- With vehicles that
have cargo protruding
from their back ends
- With non-standard
shaped vehicles (vehicle transporters or vehicles with a sidecar
fitted, etc.)
- When the height of the vehicle is low, etc.
