sufficient deceleration, such as
if a vehicle cuts in front of the
vehicle, a warning display will
flash and a buzzer will sound to
alert the driver. Depress the
brake pedal to ensure appropri-
ate vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following situations, the
warning may not operate even

When the accelerator pedal is
depressed
When a curve is detected, the
vehicle speed will begin being
reduced. When the curve ends,
the vehicle speed reduction will
end.
Depending on the situation, the
vehicle speed will then return to the
set vehicle speed.
In situations where vehicle-to-vehi-
cle distance control needs to oper- ate, such as when a preceding
vehicle cuts in front of your vehicle,
the curve speed reduction function
will be canceled.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed reduction function
may not operate:
●When the vehicle is being driven
around a gentle curve
●When the accele rator pedal is
being depressed
●When the vehicle is being driven
around an extremely short curve
If your vehicle is being driven at
approximately 50 mph (80 km/h)
or more and a lane change to
the passing lane is performed,
when the turn signal lever is
operated and the lane is
changed, the vehicle will accel-
erate up to the set speed to
assist in overtaking.
The system’s recognition of which
lane is the passing lane may be
based solely on the location of the

Emergency Driving
Stop System
The emergency driving stop
system is a system which
automatically decelerates
and stops the vehicle within
its lane if the driver
becomes unable to continue
driving the vehicle, such as
if they have suffered a medi-
cal emergency, etc.
During LTA (Lane Tracing
Assist) control, if the sys-
tem does not detect driving
operations, such as if the
driver is not holding the
steering wheel, and deter-
mines the driver is not
responsive, the vehicle will
be decelerated and stopped
within its current lane to
help avoid a collision or
reduce the impact of a colli-
sion.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving. The emer-
gency driving stop system is
designed to provide support in
an emergency where it is diffi-
cult for the driver to continue
driving, such as if they have had
a medical emergency. It is not
designed to support driving
while drowsy or in poor physical
health, or inattentive driving.
●Although the emergency driv-
ing stop system is designed to
decelerate the vehicle within its
lane to help avoid or help
reduce the impact of a collision
if the system determines that it
is difficult for the driver to con-
tinue driving, its effectiveness
may change according to vari-
ous conditions. Therefore, it
may not always be able to
achieve the same level of per-
formance. Also, if the operating
conditions are not met, this
function will not operate.
●After the emergency driving
stop system operates, if driving
becomes possible again, imme-
diately begin driving again or, if
necessary, park the vehicle on
the shoulder of the road and set
a warning reflecto r and flare to
warn other drivers of your
stopped vehicle.
●After this system operates, pas-
sengers should attend to the
driver as necessary and take
appropriate hazard prevention
measures, such as moving to a
place where safety can be
ensured, such as the shoulder
of the road or behind a guard-
rail.
●This system detects the condi-
tion of the driver through the
operation of the steering wheel.
This system may operate if the
driver is aware but intentionally
and continuously does not oper-
ate the vehicle. Also, the system
may not operate if it cannot
determine that the driver is not
responsive, such as if they are
leaning on the steering wheel.
Summary of the system
2514-5. Using the driving support systems
4
Driving
Through control state “Warning
phase 1” and “Warning phase
2”, the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “Decel-
eration stop phase” and “Stop
hold phase” and decelerate and
stop the vehicle. It will then
operate continuously in “Stop
hold phase”.
■Operating conditions
This system opera tes when all of
the following cond itions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■Operation cancelation condi-
tions
In the following si tuations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn sig nal lever is oper-
ated)
●When the driving assist switch is
pressed while in the stop and hold
phase
●When the power s witch has been
turned from ON to off
●Situations in whic h some or all of
the functions of the system cannot operate:
P. 2 1 2
■LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.

■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintai n directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel.
■E-Four (Electronic
On-Demand AWD system)
(AWD models)
Automatically controls the drive
system such as to front-wheel
drive or AWD (all wheel drive) according to various running
conditions including normal driv-
ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the TRAC/VSC/ABS sys-
tems are operating
The slip indicator light will flash
while the TRAC/VSC/ABS systems
are operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the hybrid sys-
tem to the wheels . Pressing to
turn the system off may make it eas-
ier for you to rock the vehicle in
order to free it.
To turn the TRAC system off, quickly
press and release .

■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may b e generated from
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning the TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned
off
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the hybrid system off. The EPS system should
return to normal within 10 minutes.
■Secondary Collision Brake
operating conditions

■Off-road driving precautions
Always observe t he following pre-
cautions to minim ize the risk of
death, serious injury or damage to
your vehicle:
●Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and especially your
thumbs on the ou tside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the underbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
