ESC operation
ESC ON condition
When the Engine Start/Stop button is
in the ON position, ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After both
lights go off, ESC is enabled.
When operating
When ESC is in operation, the
ESC indicator light blinks:
• When you apply your brakes under
conditions which may lock the wheels,
you may hear sounds from the brakes,
or feel a corresponding sensation in
the brake pedal. This is normal and it
means your ESC is active.
• When ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.
• If Cruise Control was in use when
ESC activates, Cruise Control
automatically disengages. Cruise
Control can be reengaged when the
road conditions allow. See “Cruise
Control (CC)” section in chapter 7 (if
equipped).
• When moving out of the mud or
driving on a slippery road, the engine
RPM (revolutions per minute) may
not increase even if you press the
accelerator pedal deeply. This is to
maintain the stability and traction of
the vehicle and does not indicate a
problem. ESC OFF condition
To cancel ESC operation:
• State 1
Press the ESC OFF button briefly. The
ESC OFF indicator light and/or message

IDLE STOP AND GO (ISG) SYSTEM
Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (i.e. red stop light, stop
sign, and traffic jam) subject to certain
prerequisite conditions being satisfied as
listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (i.e. ABS,
ESC, ESC OFF, EPS, and parking brake
warning light) may illuminate for a few
seconds due to low battery voltage.
However, it does not indicate a
malfunction with ISG system.

SPECIAL DRIVING CONDITIONS
Hazardous driving conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:
• Drive cautiously and maintain a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.
• Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
Information
The ESC system must be turned OFF
before rocking the vehicle.

Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, move your hand to the left. To
move the trailer to the right, move your
hand to the right. Always back up slowly
and, if possible, have someone guide
you.
Making turns
When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Turn signals
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signals when, in fact, they are not. It’s
important to check occasionally to be
sure the trailer bulbs are still working.
You must also check the lights every time
you disconnect and then reconnect the
wires.
WARNING
Do not connect a trailer lighting system
directly to your vehicle’s lighting
system. Use an approved trailer wiring
harness. Failure to do so could result in
damage to the vehicle electrical system
and/or personal injury. We recommend
that you consult an authorized
HYUNDAI dealer for assistance.
Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get overheated and may
not operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have a automatic
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize heat
build-up and extend the life of your
transmission.
