The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.✽ ✽NOTICEA click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.
ESC operationESC ON condition
 When the ignition is turnedON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.
 Press the ESC OFF button for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
 When starting the engine, you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem. When operating
When the ESC is in operation,
ESC indicator light blinks.
 When the Electronic StabilityControl is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and indi-
cates nothing unusual.
 When moving out of the mud or driving on a slippery road,
pressing the accelerator
pedal may not cause the
engine rpm (revolutions per
minute) to increase.
ESC operation offESC OFF state
 To cancel ESC operation,press the ESC OFF button
(ESC OFF indicator light illu-
minates).
 If the ignition switch is turned to LOCK position when ESC
is off, ESC remains off. Upon
restarting the engine, the
ESC will automatically turn
on again.

Active ECO operation Active ECO helps improve fuel efficiency
by controlling the engine and transaxle.
But fuel-efficiency can be changed by the
driver's driving habits and road condi-
tions.
 When the Active ECO button ispressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
 When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
 If Active ECO is turned off, it will return to the normal mode.
Limitation of Active ECO
operation:If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
 When the coolant temperature is low:The system will be limited until engine
performance becomes normal.
 When driving up a hill: The system will be limited to gain powerwhen driving uphill because the engine
torque is restricted.
 When using sports mode: The system will be limited according tothe shift location.
 When the accelerator pedal is deeply pressed for a few seconds:
