Owners Manual_USA_M0C043_en

Driving
●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).

Maintenance and care
brakes several times to dry the

■Bumpers and wh eel arch mold-
ings
Do not scrub with abrasive cleaners.

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.

cloth to remove any remaining
moisture.

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
