QSounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and hill-
start assist control systems
OA sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the hybrid
system is started or just after the vehicle
begins to move. This sound does not indi-
cate that a malfunction has occurred in
any of these systems.
OAny of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehi- cle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
QECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred.
OOperating sound heard from the engine
compartment when the brake pedal is
operated.
OMotor sound of the brake system heard
from the front part of the vehicle when
the driver’s door is opened.
OOperating sound heard from the engine
compartment when one or two minutes
passed after the stop of the hybrid sys-
tem.
QActive Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is oper-
ated, operation sounds and vibrations may
be generated from the brake system, but
this is not a malfunction.
QEPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
QAutomatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems will be automatically re-
enabled in the following situations:
OWhen the power switch is turned off
OIf only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases.
QSecondary Collision Brake operating
conditions
The system operates when the SRS airbag
sensor detects a collision while the vehicle
is in motion.
However, the system does not operate
when the components are damaged.
QSecondary Collision Brake automatic
cancellation
The system is automatically canceled in any
of the following situations.
OThe vehicle speed drops to approxi-
mately 6 mph (10 km/h)
OA certain amount of time elapses during
operation
OThe accelerator pedal is depressed a
large amount
QOperating conditions of Active Corner-
ing Assist
The system operates when the following
occurs.
OTRAC/VSC can operate
OThe driver is attempting to accelerate
while turning
OThe system detects that the vehicle is
drifting to the outer side
OThe brake pedal is released
QReduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering 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.

2584-6. Driving tips
4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.219)
The Eco-friendly driving is possible by
keeping the bar display of Hybrid Sys-
tem Indicator within Eco area. ( P.77,
82)
Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gen-
tly and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
