If the system then determines that the risk of collision is ext remely high, the
alert changes to a continuous beeping sound and stronger brakin g control
is activated. Despite any evasive action taken by the driver, if the system
subsequently determine s that a collision is unavoidable, brakin g and
engine output are con trolled by the system.
When the vehicle is completely stopped by the automatic braking system, a
short tone “3 intermittent beeps , 1 short beep and 1 long beep” will sound
and braking will be gradually released and the vehicle will sta rt creeping. To
stop the vehicle completely, d epress the brake pedal after the vehicle has
stopped.
●Neither first braking nor secondary braki ng will operate in the following
cases.
• The vehicle speed is approximately 1 mph (1 km/h) or less (Whe n the shift
lever is in the N position and your vehicle speed is approximat ely 2 mph (4
km/h) or less) or 100 mph (160 km/h) or more.
• VSC is active.
●If the system detects the stop lights of the vehicle in front, your vehicle will
start decelerating earlier than if it does not.
●There are some cases where the first braking is applied for a l onger period
of time. One of the reasons for t his is due to a large speed difference with
an obstacle in front. In those cases, stronger or weaker brakin g control
may be activated.
After the Pre-Collision Braki ng System operation, a message
appears and stays on the meter display for a certain period of time.

WARNING
●There are limits to the situation
judgment capabilities of the
Adaptive Cruise Control system.
Deceleration may not take place
in time in the following situa-
tions. Apply the brake pedal to
decelerate the vehicle if neces-
sary.
• The speed difference with the vehicle in front is too large or
the vehicle in front decelerates
unexpectedly.
• The decelerating vehicle in front unexpectedly sl ows down or
suddenly brakes.
●If the alert/notification sounds
frequently, do not use Adaptive
Cruise Control.
●Even when the following dis-
tance is short, the “Obstacle
Detected” warning may not acti-
vate in the following situations.
• The difference in speed with the vehicle in front is small. The two
vehicles are traveling at almost
the same speed.
• The vehicle in fr ont is traveling
faster than your vehicle. The fol-
lowing distance is gradually
increasing.
• Another vehicle cuts into your lane very close to your vehicle.
• The vehicle in front decelerates suddenly.
• There are repeated uphill and downhill grades.
*: The recognition status of the
lead vehicle using the stereo
camera can be confirmed by the
illumination status of the lead
vehicle indicator. (
P.196)
NOTICE
●After Adaptive Cruise Control
has started, it maintains control
continuously according to the
behavior of the veh icle in front.
When your vehicle comes to a
stop because the vehicle in front
has stopped, the automatic
braking function will be can-
celed immediately after stop-
ping and the veh icle will start
creeping forward gradually (at
the same time 3 intermittent
beeps, 1 short beep and 1 long
beep will sound). Be sure to
depress the brake pedal and
stop the vehicle completely.
Note that the v ehicle is not
maintained at a standstill posi-
tion and will not automatically
start moving from a standstill
position.
●Braking may not be sufficient
depending on the following con-
ditions. Depress the brake
pedal and decelerate as neces-
sary.
• Vehicle conditions (amount of load, number of occupants, etc.)
• Road conditions (grade, slip- periness, shape, bumps, etc.)
• Vehicle maintenance condition (brake systems, tire wear, air
pressure, temporary spare tire
is being used, etc.)
• The brakes are cold. (For exam- ple, just after the engine is
started or the outside tempera-
ture is low.)
• For a short period of time when driving after the engine is
started until the engine has
warmed-up
• The brakes are overheated on downhill grades (braking perfor-
mance may be reduced).

will drive at that constant speed.
If a vehicle in front is detected while
accelerating to the set vehicle
speed, vehicle following will be
started again.
●When the brakes are applied by
Adaptive Cruise Control, the vehi-
cle’s stop lights will illuminate.
●Even if there is no lead vehicle
present, on a downhill grade, the
Adaptive Cruise Control’s auto-
matic brake may operate in order
to maintain the set vehicle speed.
●Some noises may be audible
during automatic braking. This is
caused by the braking control and
does not indicate a malfunction.
●To temporarily accelerate quickly,
use the accelerator pedal. After
accelerating, the vehicle will grad-
ually return to the set vehicle
speed shown in the set vehicle
speed display.
●If the vehicle in front is no longer
detected while your vehicle is still
controlled by the automatic brak-
ing operation, th e brake will be
automatically released gradually.
Depress the accelerator pedal if
necessary.
●The lead-vehicle following func-
tion has the following characteris-
tics:
• If the lead vehicle’s stop lights are
detected, deceleration will start
earlier than without detection.
• If the vehicle moves to the fast
lane while traveling more than approximately 37 mph (60 km/h),
the system starts acceleration to
the set vehicle speed more quickly
because it is linke
d with the turn
signal.
• If the setting of driving lane is dif-
ferent from the actual driving
direction, the vehicle may start to
accelerate faster than usual when
the driver signals a lane change to
move from the passing lane to the
driving lane. ( P.400)
●Cruise control acceleration char-
acteristics can be set to one of
four levels. ( P.400)
■Increasing the set vehicle
speed

switch
Push to the “+ RES” side
briefly.
Every time the switch is pushed,
the set vehicle speed will increase

While the switch is being pushed,
the set vehicle speed will increase

When operating the switch, the
set vehicle speed changes on
the meter display.
NOTICE
If the driver oper ates the brake
pedal during automatic braking,
the pedal may feel stiff; however,
this is not a malfunction. By
depressing the brake pedal fur-
ther you can apply more braking
force. When the brake pedal is
released it will return to its original
condition.

Pre-Collision Throttle
Management*
When an obstacle is
detected in front of the vehi-
cle, and the vehicle is
stopped or traveling very
slowly, if the system deter-
mines that the accelerator
pedal has been depressed
by more than the necessary
amount (due to driver error),
it greatly restricts engine
output and ensures that
vehicle forward movement
is slower than normal in
order to give the driver addi-
tional time to brake or react.
During system operation, an
alert will sound repeated
short beeps and a pop-up
display will be displayed.
This function only activates
when the shift lever is in the
D or M position.

WARNING
Do not rely excessively on
Pre-Collision Throttle Manage-
ment. Pre-Collision Throttle Man-
agement is not designed to help
you avoid collisions in all situa-
tions. Always check the shift lever
and pedal positions as well as the
surrounding environment before
starting and operating the vehicle.
Relying only on Pre-Collision
Throttle Management could result
in an accident.
●Pre-Collision Throttle Manage-
ment is not designed to main-
tain the vehicle in a stopped
condition.
●Pre-Collision Throttle Manage-
ment will not re duce accelera-
tion under all conditions. It is
also not designed to prevent
collisions.
●Pre-Collision Throttle Manage-
ment will operate when an
obstacle is detected in front.
However, this function will not
reduce acceleration in cases
where no obstacle is detected
(for example when approaching
a cliff, etc.).
●Do not intentionally depress the
accelerator pedal excessively
when there are obstacles
nearby. If the driver relies only
on Pre-Collision Throttle Man-
agement to contr ol acceleration,
collisions may occur.
