4-5. Using the driving support systems
■ Vehicle speeds at which the system can
operate
● Detectable object crossing the road
assistance
Approximately 20 to 35 mph (30 to 60
km/h)
● Detectable object on the side of the road
assistance
Approximately 20 to 35 mph (30 to 60
km/h)
● Preceding vehicle deceleration assis-
tance
Approximately 15 mph (20 km/h) or more
● Curve deceleration assistance
Approximately 15 mph (20 km/h) or more
● Steering assist within a lane
Approximately 5 to 80 mph (10 to 140
km/h)
■ System operation will be canceled when
● In the following situations, system opera-
tion will be canceled:
• When the dynamic radar cruise control
or cruise control is operating
•When the PCS is off
• Situations in which some or all of the
functions of the system cannot operate:
P.245
• When the P, R or N shift position is
selected
• The driver’s seat belt is unfastened
● In the following situations, the brake
operation assist will be canceled:
• Approximately 9 mph (15 km/h) or less
• When a certain vehicle speed has been
reached, as judged by the system,
according to the surrounding conditions
● In the following situations, system opera-
tion may be canceled:
• When the brake control or output
restriction control of a driving support
system operates (For example: PCS,
drive-start control)
• When the system determines that a
detected object has moved away from
the vehicle
• When lane lines can no longer be
detected
• When the brake pedal has been
depressed
• When the accelerator pedal has been
depressed
• When the steering wheel has been oper-
ated with more than a certain amount of
force
• When the turn signal lever is operated to
the left/right turn position
■ Situations in which the system may
not operate properly
● Situations in which the lane may not be
detected: P.245
● When a detectable object stops
immediately before entering the path
of the vehicle
● When passing extremely close to a
detectable object behind a guardrail,
fence, etc.
● When changing lanes while overtak-
ing a detectable object
● When passing a detectable object that
is changing lanes or turning left/right
● When there are objects (guardrails,
power poles, trees, walls, fences,
poles, traffic cones, mailboxes, etc.) in
the surrounding area
● When there are patterns or a painting
ahead of the vehicle that may be mis-
taken for a detectable object
● When passing through a place with a
low structure above the road (tunnel
with a low ceiling, traffic sign, sign-
board, etc.)
● When driving on snowy, icy, or rutted
roads
● When a detectable object is
approaching your vehicle
● When your vehicle or a detectable
