Electronic stability control (ESC)
(if equipped)
0+'
The electronic stability control (ESC)
system is designed to stabilize the ve‐ hicle during cornering maneuvers. ESC
checks where you are steering and
where the vehicle is actually going. ESC applies the brakes at individual wheels
and intervenes with engine manage‐
ment system to stabilize the vehicle.
WARNING
Never drive too fast for the roadconditions or too quickly when cor‐nering. Electronic stability control(ESC) will not prevent accidents. Ex‐cessive speed in turns, abrupt ma‐neuvers and hydroplaning on wetsurfaces can still result in serious ac‐cidents. Only a safe and attentivedriver can prevent accidents byavoiding maneuvers that cause thevehicle to lose traction. Even withESC installed, always follow all thenormal precautions for driving - in‐cluding driving at safe speed for theconditions.
The electronic stability control (ESC)
system is an electronic system de‐ signed to help the driver maintain vehi‐
cle 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 speed and to leave a suf‐ ficient margin of safety. When you apply your brakes under
conditions which may lock the wheels,
you may hear a L

ESC operation
ESC ON condition
-• When the engine start/stopbutton is turned ON, ESC
and ESC OFF indicator lights
illuminate for approximate‐
ly 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 illumi‐
nate). 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 tick‐
ing sound. This is the ESC
performing an automatic
system self-check and does not indicate a problem.
When operating
When the ESC is in operation, ESC indicator light blinks. • When the Electronic Stabili‐ ty Control is operating
properly, you can feel a
slight pulsation in the vehi‐
cle. This is only the effect of brake control and indi‐
cates nothing unusual.
• When moving out of the mud or slippery road, the
engine rpm (revolution per
minute) may not increase
even if you press the accel‐ erator pedal deeply. This is
to maintain the stability
and traction of the vehicle
and does not indicate a
problem.
ESC operation off
ESC OFF state
This car has 2 kinds of ESC off states.If the engine stops when ESC
is off, ESC remains off. Upon
restarting the engine, the ESCwill automatically turn on
again.
