Driving
The estimated course lines targe t flat surfaced objects (such as the
road). It is not possible to determine the position of three-dimen-
sional objects (such as vehicles) using the estimated course li nes
and distance guide lines. When approaching a three-dimensional
object that extends outward (such as the flatbed of a truck), b e care-
ful of the following.
Since the estimated course line
is displayed for a flat road sur-
face, it cannot depict the posi-
tion of three-dimensional objects
(such as vehicle bumpers, etc.)
that are in positions higher than the surface of the road. Even if
the bumpers of the vehicle is on
the outside of the estimated
course line in the image, in real-
ity, the vehicles are on a colli-
sion course.
WARNING
●When a sensor indicator on the in
tuitive parking assist display illumi-
nates in red or a buzzer sounds continuously, be sure to check the area
around the vehicle immediately a nd do not proceed any further until
safety has been ensured, otherwise an unexpected accident may o ccur.

Owners Manual_USA_M0C052_en
system detects a panic stop sit-
uation
■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintai n directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■AVS (Adaptive Variable
Suspension System) (if
equipped)
The damping force of the shock
absorbers are independently
controlled for the 4 wheels
according to factors including
the road surface conditions and
driving operation, contributing
toward enhancing smooth driv- ing comfort and superior stabil-
ity, and helping to maintain
vehicle posture.
In addition, the damping force
can be changed by selecting the
drive mode with the driving
mode select (
P.358), and driv-
ing comfort can be ensured
during off-road driving by setting
the front-wheel drive control
switch to “4L”.( P.361)
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the
TRAC/VSC/ABS/Trailer Sway
Control systems are operating
The slip indicator light will flash
while the TRAC/VSC/ABS/Trailer
Sway Control systems are operat-
ing.

●The accelerator pedal is
depressed
●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,
Trailer Sway Control, TRAC and
hill-start assist control systems
●A sound may be heard from the
hybrid system compartment when
the brake pedal is depressed
repeatedly, when the hybrid sys-
tem is started or just after the vehi-
cle begins to move. This sound
does not indicate that a malfunc-
tion has occurred in any of these
systems.
●Any of the following conditions
may occur when t he 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.
●Motor sound of the brake system
heard from the front part of the
vehicle when the driver’ door is
opened.
●Operating sound heard from the
engine compartment when one or
two minutes passed after the stop
of the hybrid system.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sou nd (whirring sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of
TRAC, Trailer Sway Control and
VSC systems
After turning the TRAC, Trailer
Sway Control and VSC systems off,
the systems will be a utomatically re-
enabled in the following situations:
●When the power switch is turned
off
●If only the TRAC sy stem is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned of f, automatic re-
enabling will not occur when vehi-
cle speed increases.
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period o f time. The steer-
ing wheel may f eel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle a nd 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 de tects a collision
while the vehicle is in motion. How-
ever, the system does not operate
when the components are dam-
aged.
■Secondary Collision Brake
automatic cancelation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops to
approximately 0 mph (0 km/h).
●A certain amount of time elapses
during operation

Maintenance and care
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with an
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■Precautions regarding the
exhaust pipe
Exhaust gases cause the exhaust
pipe to become quite hot. When
washing the vehicle, be careful
not to touch the pipe until it has
cooled sufficiently, as touching hot
exhaust pipe can cause burns.
■When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the wiper switch is in “AUTO”,
the wipers may operate unexpect-
edly in the following situations,
and may result in hands being
caught or other serious injuries
and cause damage to the wiper
blades.
Off
“AUTO”
●When the upper part of the
windshield where the raindrop
sensor is located is touched by
hand
●When a wet rag or similar is
held close to the raindrop sen-
sor
●If something bumps against the
windshield
●If you directly touch the raindrop
sensor body or if something
bumps into the ra indrop sensor
■Precaution regarding the rear
bumper with Blind Spot Moni-
tor (vehicles with painted rear
bumper)
If the paint of th e rear bumper is
chipped or scratched, the follow-
ing systems may not function cor-
rectly. If this occurs, consult your
