Driving
■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 dep ressed repeat-
edly, when the hybrid system is
started or just after the vehicle
begins to move.
●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’s door is
opened.
●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 b e generated from
the brake system, but this is not a
malfunction.
■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
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 oc cur 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 effect iveness 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 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 in
any of the following situations.
●The vehicle speed is below 6 mph
(10 km/h)
●Components are damaged
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.

damage to the UV protective coat-
ing, observe the following:
●If the windows are dirty, gently
wipe them with a cloth soaked in
water or lukewarm water as soon
as possible.
●If the windows are very dirty, do
not open and close them repeat-
edly.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in
the vehicle, such as on the floor,
on the rear seats, in the hybrid
battery (traction battery) air
intake vent or in the luggage
compartment. (P.77)
Doing so may cause the hybrid
battery, electrical components,
etc. to malfunction or catch fire.
●Do not get any of the SRS com-
ponents or wiring in the vehicle
interior wet.
( P.34)
An electrical malfunction may
cause the airbags to deploy or
not function properly, resulting
in death or serious injury.
●Do not let the wireless charger
( P.351) get wet. Failure to do
so may cause the charger to
become hot and cause burns or
could cause electric shock
resulting in death or serious
injury.
■Cleaning the interior (espe-
cially instrument panel)
Do not use polish wax or polish
cleaner. The instrument panel
may reflect off the windshield,
obstructing the dr iver’s view and
leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents

direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.
●Do not place items made of
vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■Water on the floor
Do not wash the v ehicle floor with
water.
Vehicle systems such as the
audio system may be damaged if
