■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 while 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 deviate from the lane
while driving around a curve while the lane centering function is operating.
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the 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 lon-
ger.
■Vehicle sway warning function
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 simultane-ously displayed on the multi-information

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines 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 distanc e may become
shorter.
Example of constant 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 appe ars
When a vehicle is detected 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 ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns 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 t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position

●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 vehicles 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 accelerates by depressing the accel-
