Driving
• The dynamic radar cruise control with full-speed range is operating in
vehicle-to-vehicle distance control mode.
• Width of traffic lane is approximately 10 to 13 ft. (3 to 4 m).
• Turn signal lever is not operated.
• Vehicle is not being driven around a sharp curve.
• No system malfunctions are detected. ( P. 257)
• Vehicle does not accelerate or decelerate by a fixed amount or more.
• Steering wheel is not operated with a steering force level suitable for
changing lanes.
• ABS, VSC, TRAC and PCS are not operating.
• TRAC or VSC is not turned off.
• Hands off steering wheel warning is not displayed. ( P. 2 5 6 )
• The vehicle is being driven in the center of a lane.
• Steering assist function is not operating.
■ Temporary cancelation of functions
●When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored. ( P. 254)
● If the operation conditions ( P. 254) are no longer met while the lane cen-
tering function is operating, the buzzer may sound to indicate that the func-
tion has been temporarily canceled.
■ Steering assist function/lane centering function
●Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the function is operating or the function may not
operate at all.
● The steering control of the function is overridden by the drive r’s steering
wheel operation.
● Do not attempt to test the operation of the steering assist fun ction.
■ Lane departure alert function
●The warning buzzer may be difficult to hear due to external noi se, audio
playback, etc.
● If the edge of the course
* is not clear or straight, the lane departure alert
function may not operate.
● Vehicle with BSM: It may not be possible for the system to determine if there
is a danger of a collision with a vehicle in an adjacent lane.
● Do not attempt to test the operation of the lane departure aler t function.
*: Boundary between asphalt and the side of the road, such as gra ss, soil, or
a curb

2564-5. Using the driving support systems
■Hands off steering wheel warning
●When the system determines the driver is not holding the steering wheel
while the lane centering function is operating.
If the driver continues to keep their hands off of the steering wheel, the
buzzer sounds, the driver is warned and the function is temporarily canceled.
This warning also operates in the same way when the driver continuously
operates the steering wheel only a small amount.
● When the system determines that the vehicle may deviate from th e lane
while driving around a curve while the lane centering function is operating.
Depending on the vehicle condition and road conditions, the war ning may not
operate. Also, if the system determines that the vehicle is driving around a
curve, warnings will occur earlier than during straight-lane dr iving.
● When the system determines that the driver is driving without h olding the
steering wheel while the steering wheel assist of the steering assist function
is operating.
If the driver continues to keep their hands off of the steering wheel and the
steering wheel assist is operating, the buzzer sounds and the d river is
warned. Each time the buzzer sounds, the continuing time of the buzzer
becomes longer.
■ Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may n ot operate.
In the following situations, a warning mes-
sage urging the driver
to hold the steering
wheel and the symbol shown in the illus-
tration are displayed on the multi-informa-
tion display to warn the driver. The
warning stops when the system deter-
mines that the driver holds the steering
wheel. Always keep your hands on the
steering wheel when using this system,
regardless of warnings.
When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in
the illustration are simultaneously dis-
played on the multi-information display.

2684-5. Using the driving support systems
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may b e deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.
Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. ( P. 274)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 20 mph
[30 km/h]) and press the “- SET”
switch to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.

2724-5. Using the driving support systems
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, war nings may not occur even when th e
vehicle-to-vehicle distance is small.
● When the speed of the preceding vehicle matches or exceeds
your vehicle speed
● When the preceding vehicle is traveling at an extremely slow
speed
● Immediately after the cruise control speed was set
● When depressing the accelerator pedal
While driving in vehicle-to-vehi cle distance control mode, this function
will reduce the vehicl e speed, if it is determined to be necess ary.
■Function operation
When the steering wheel begins to be turned, the vehicle speed will
begin being reduced. When the steering wheel is returned to the
center position, the vehicl e speed reduction will end.
Depending on the situat ion, the vehicle speed will then return to the
vehicle-to-vehicle distanc e control mode set speed.
In situations where vehicle-to-v ehicle distance control needs to
operate, such as when a preceding vehicle cuts in front of your
vehicle, the curve speed reduction function will be canceled.

2784-5. Using the driving support systems
■Conditions under which the vehic le-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after th e vehicle
accelerates by depressing the accelerator pedal
■ Situations in which the curve sp eed reduction function may not operate
properly
In situations such as the following, the curve speed reduction function may
not operate properly:
● When the vehicle is being driven around a curve on an incline/d ecline
● When the course of the vehicle differs from the shape of the cu rve
● When the vehicle speed is excessively high when entering a curv e
● When the steering wheel is suddenly operated
●
When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

■If “Clean dirt from lens” is dis played on the audio system screen
A rear camera lens may be dirty or covered with snow or ice. In such cases, if
it is removed from the rear camera lens, the system should retu rn to normal.
(It may be necessary to drive the vehicle for some time before the system
returns to normal.)
■ If “RCD unavailable” is displ ayed on the audio system screen
● If this message is displayed after the battery has been disconnected and
reconnected, fully turn the steering wheel to the left and then the right on
level ground.
● If this message is displayed only when the R shift position is selected, the
rear camera lens may be dirty. Clean the rear camera lens.
■ Situations in which the syst em may not operate properly
● Some pedestrians, such as the following, may not be detected by the rear
camera detection function, preventing the function from operati ng properly:
• Pedestrians who are squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• Pedestrians riding a bicycle, skateboard, or other light vehic le
• Pedestrians wearing unusual clothing, such as a costume
• Pedestrians whose body is partially hidden by a cart or other object
• Pedestrians which are obscured by darkness, such as at night
● In some situations, such as the following, pedestrians may not be detected
by the rear camera detection function, preventing the function from operat-
ing properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are at tached) or
scratched
• When a very bright light, such as the sun, or the headlights o f another
vehicle, shines directly into the rear camera
• When backing up in a place where the surrounding brightness ch anges
suddenly, such as at the entrance or exit of a garage or underg round
parking lot

3284-5. Using the driving support systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippe ry
road surfaces by controlling steering performance.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Active Cornering Assist (ACA) (if equipped)
Helps to prevent the vehicle from sliding to the outer side by per-
forming inner wheel brake control when attempting to accelerate
while turning
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start -
ing on an uphill
Driving assist systems
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

3294-5. Using the driving support systems

Driving
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆Adaptive Variable Suspension System (if equipped)
By independently controlling the damping force of the shock
absorbers for each of the 4 wheels according to the road and dr iv-
ing conditions, this system helps riding comfort with superior vehi-
cle stability, and helps good vehicle posture ( P. 3 2 4 )
◆The Secondary Collision Brake
When the SRS airbag sensor detects a collision and the system
operates, the brakes and stop li ghts are automatically controlled to
reduce the vehicle speed and hel p reduce the possibility of further
damage due to a secondary collision.
◆Dynamic Torque Control AWD system (if equipped)
Automatically switches from fron t-wheel drive to all-wheel drive
(AWD) according to the driving conditions, helping to ensure re li-
able handling and stability. Ex amples of conditions where the s ys-
tem will switch to AWD are when cornering, going uphill, starting off
or accelerating, and when the road surface is slippery due to s now,
rain, etc.
The slip indicator light will flash
while the TRAC/VSC systems are
operating.

■Sounds and vibrations caused by the ABS, brake assist, VSC, TRA C and
hill-start assist control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just aft er the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above system s are
operating. None of these indicates that a malfunction has occur red.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a s top.
• The brake pedal may pulsate slightly after the ABS is activate d.
• The brake pedal may move down slightly after the ABS is activa ted.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.
■ Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is operated, operation sounds and vibra-
tions may be generated from the brake system, but this is not a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the engine switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases.
■ Operating conditions of Active Cornering Assist
The system operates when the following occurs.
●TRAC/VSC can operate
● The driver is attempting to accelerate while turning
● The system detects that the vehicle is sliding to the outer sid e
● The brake pedal is released
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.
However, the system does not operate in any of the following si tuations.
● The vehicle speed is below 6 mph (10 km/h)
● Components are damaged
