ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:

[Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and Parking Brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.

[When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
Turning ESC off does not affect ABS or
standard brake system operation.
Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management:

[ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.

[Never drive too fast for the road
conditions. VSM will not prevent
accidents. Excessive speed in bad
weather, on slippery and uneven
roads can result in severe accidents.

Information
When the engine is automatically started
by ISG system, warning lights (for
example, ABS, ESC, ESC OFF, MDPS,
and parking brake warning light) may
illuminate for a few seconds due to low
battery voltage.
However, it does not indicate a

Emergency Situations
ORS081001ORS081001
The hazard warning flasher serves as
a warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.
It should be used whenever emergency
repairs are being made or when the
vehicle is stopped near the edge of a
roadway.
To turn the hazard warning flasher on
or off, press the hazard warning flasher
button with the Engine Start/Stop button
in any position. The hazard warning
flasher button is located in the center
fascia panel. All turn signal lights will
flash simultaneously.
• The hazard warning flasher operates
regardless of whether your vehicle is
running or not.
• The turn signals do not work when the
hazard flasher is on.
If the Engine Stalls While Driving
• Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
• Turn on your hazard warning flasher.
• Try to start the engine again. If your
vehicle will not start, we recommend
that you contact an authorized retailer
of Genesis Branded products or seek
other qualified assistance.
If the Engine Stalls at a Crossroad
or Crossing
If the engine stalls at a crossroads or
crossing, if safe to do so, shift the gear to
N (Neutral) and then push the vehicle to
a safe location.
