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
