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.
● 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.
■ 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.
■ EPS operation sound
When the steering wheel is oper-
ated, a motor sound (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 automatically re-
enabled in the following 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 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 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

airbag sensor detects 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
