4185-5. Using the driving support systems
NOTICE
●In situations such as the follow-
ing, it may not be possible for
the system to provide assis-
tance to a registered parking
spot:
• When the appearance of the parking space is affected by the
shadow of the vehicle or trees
• When an object is detected in the registered parking space
• When a pedestrian or passing vehicle is detected during assis-
tance
• When the position the vehicle is stopped when assistance is
started differs from the position
when registration was per-
formed
• When the registered parking space cannot be reached due to
the existence of parking blocks,
etc.
• When the road surface around the parking space has changed
(road surface has degraded or
been resurfaced)
• When the sunlight conditions differ from when registration
was performed (due to weather
or time of day)
• When the sun is shining directly into a camera, such as in the
early morning or evening
• When the color or brightness of the road surface is uneven
• When a light is temporarily shined on the parking space
(lights of another vehicle, secu-
rity light, etc.)
• When the road surface around the parking space has the same
repeating pattern
• When there is a low protrusion on the road surface near the
parking space
• When the parking space is on a slope
• When a camera has been splashed by hot or cold water
and the lens has fogged up
• When a camera lens is dirty or covered with water droplets
• When accessories which obstruct the view of the camera
are installed
If assistance is ended during
registration, perform registration
again.
●When registering a parking
space to the memory function, if
the road surface cannot be
detected “No available parking
space to register” will be dis-
played.
●When using the memory func-
tion, make sure to stop immedi-
ately in front of the stop
position. Otherwise the parking
space may not be able to be
detected correctly or assis-
tance may not be provided to
the point that the vehicle is fully
parked.
●Do not use the memory function
if a camera has been subjected
to a strong impact or images of
the panoramic view monitor are
misaligned.
●If a camera has been replaced,
as the installation angle of the
camera will have c hanged, it will
be necessary to reregister park-
ing spaces of the memory func-
tion.

●The accelerator pedal is not
depressed
●The parking brake is not engaged
●The power switch is in ON
■Automatic system cancelation
of hill-start assist control
The hill-start assist control will turn
off in any of the following situations:
●Shift the shift position to P or N.
●The accelerator pedal is
depressed
●The brake pedal is depressed and
the parking brake is engaged
●A maximum of 2 seconds have
elapsed after the brake pedal is
released
●The power switch is turned to OFF
■Sounds and vibrations caused
by the ABS, brake assist, VSC,
TRAC and hill-start assist con-
trol systems
●A sound may be heard from the
engine compartment when the
brake pedal is depressed repeat-
edly, when the hybrid system is
started or just after 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 sys-
tems are operating. None of these
indicates that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also
after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard
in the following cases, but it does
not indicate that a malfunction has
occurred.
●Operating sound heard from the
engine compartment when the
brake pedal is operated.
●Operating sound heard from the engine compartment when one or
two minutes passed after the stop
of the hybrid system.
■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations 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
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 vehi-
cle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is attempting 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 effectivenes s 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
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of the following situa-
tions.
●The vehicle speed drops to
approximately 0 mph (0 km/h).
●A certain amount of time elapses
during operation
●The accelerator pedal is
depressed a large amount
WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow-covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
