• Width of traffic lane is approximately 3 m (9.8 ft.) or more.
• No system malfunctions are detected.
( P.248)
■Temporary cancelation of functions
●When operation conditions are no
longer met, a function may be tempo- rarily canceled. However, when the
operation conditions are met again,
operation of the function is automati- cally restored. ( P.246)
■Steering assist function
●Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the func-
tion is operating or the function may not operate at all.
●The steering control of the function is overridden by the driver’s steering
wheel operation.
●Do not attempt to test the operation of
the steering assist function.

is a danger of a collision with a vehicle
in an adjacent lane.
●Do not attempt to test the operation of
the lane departure alert function.*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the
steering wheel and the symbol shown in the illustration are displayed on the
multi-information display to warn the
driver. The warning stops when the sys-
tem determines 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
driver is driving without holding the
steering wheel wh ile the system 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 oper-
ates the steering wheel only a small amount.
●When the system determines that the vehicle may not turn and instead
depart from its lane while driving
around a curve
Depending on the vehicle condition and
road conditions, the warning may not operate. Also, if t he system determines
that the vehicle is driving around a
curve, warnings will occur earlier than during straight-lane driving.
●When the system determines that the driver is driving without holding 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 driver is warned.
Each time the buzzer sounds, the con- tinuing time of the buzzer becomes
longer.
■Vehicle sway warning function
When the system determines that the

4-5. Using the driving support systems
Driving
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the v ehicle is driven to a region where the over-
taking lane is on a different side from wher e the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (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 over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any precedi ng vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will come on and a message will be dis-
played on the multi-information display.
Press the switch again to deactivate 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.256)
2Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 km/h
[20 mph]) 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.
To change the set speed, press the
“+RES” or “-SET” switch until the

to inform the driver of the need for cau-
tion while driving. If a warning message is shown on the multi-information dis-
play, read the message and follow the
instructions. ( P.222, 520)
■When the sensor may not be cor- rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning ( P.255) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load in
the luggage compartment, etc.)
●Preceding vehicle has an extremely
high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as necessary.
As the sensor may not be able to cor-
rectly detect vehicl es ahead, the system may not operate properly.
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decel-erates 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 the vehicle

This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to -vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of const ant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the v ehicle is driven to a region where the over-
