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.

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
