Driving your vehicle
Electronic Stability Control
(ESC)
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle dur-
ing cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies
braking pressure to any one of the vehi-
cle's brakes and intervenes in the engine
management system to assist the driver
with keeping the vehicle on the intended
path. It is not a substitute for safe driving
practices. Always adjust your speed and
driving to the road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF indi-
cator lights illuminate for approximately
three seconds. After both lights go off,
the ESC is enabled.
When operating
When the 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 the ESC activates, the engine may not respond to the accelerator as
it does under routine conditions.
If the Cruise Control was in use when the ESC activates, the Cruise Control
automatically disengages. The Cruise
Control can be reengaged when the
road conditions allow. See "Cruise
Control System" later in this chapter. (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 acceler-
ator pedal deeply. This is to maintain
the stability and traction of the vehicle
and does not indicate a problem.
OAD055010N
Never drive too fast for the road
conditions or too quickly when cor-
nering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on
wet surfaces can result in severe
accidents.

ESC OFF condition
To cancel ESC operation :
State 1
Press the ESC OFF button briefly. The
ESC OFF indicator light and message
will illuminate. In this state, the traction
control function of ESC (engine manage-
ment) is disabled, but the brake control
function of ESC (braking management)
still operates.
Press and hold the ESC OFF button con-
tinuously for more than 3 seconds. The
ESC OFF indicator light and message
illuminates and a warning chime sounds.
In this state, both the traction control
function of ESC (engine management)
and the brake control function of ESC
(braking management) are disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the engine,
the ESC will automatically turn on again.
Indicator lights
When the ignition switch is placed to the
ON position, the ESC indicator light illu-
minates, then goes off if the ESC system
is operating normally.
The ESC indicator light blinks whenever
the ESC is operating.
If ESC indicator light stays on, your vehi-
cle may have a malfunction with the ESC
system. When this warning light illumi-
nates have your vehicle checked by an
authorized HYUNDAI dealer as soon as
possible.
The ESC OFF indicator light comes on
when the ESC is turned off.

LKAS Malfunction
If there is a problem with the system a
message will appear for a few seconds. If
the problem continues the LKAS failure
indicator will illuminate.
LKAS failure indicator
The LKAS failure indicator (yellow) will
illuminate if the LKAS is not working
properly. Have your vehicle checked by
an authorized HYUNDAI dealer.
When there is a problem with the
system do one of the following:
Turn the system on after turning theengine off and on again.
Check if the ignition switch is in the ON position.
Check if the system is affected by the weather. (ex: fog, heavy rain, etc.)
Check if there is foreign matter on the camera lens.
If the problem is not solved, have your
vehicle checked by an authorized
HYUNDAI dealer.

Cruise Control operation
1. CRUISE indicator
2. SET indicator
The Cruise Control system allows you to
drive at speeds above 20 mph (30 km/h)
without depressing the accelerator pedal.
Information
• During normal cruise control operation,when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.
• Before activating the cruise control function, the system will check to verify
that the brake switch is operating nor-
mally. Depress the brake pedal at least
once after turning ON the ignition or
starting the engine.

Take the following precautions:
If the Cruise Control is left on,
("CRUISE" indicator light in the
instrument cluster is illuminated)
the Cruise Control can be activat-
ed unintentionally. Keep the
Cruise Control system off
("CRUISE" indicator light OFF)
when the Cruise Control is not in
use, to avoid inadvertently set-
ting a speed.
Use the Cruise Control system
only when traveling on open
highways in good weather.
Do not use the Cruise Control
when it may be unsafe to keep
the vehicle at a constant speed:
- When driving in heavy traffic or
when traffic conditions make it
difficult to drive at a constant
speed
- When driving on rainy, icy, or snow-covered roads
- When driving on hilly or windy roads
- When driving in windy areas
- When driving with limited view (possibly due to bad weather
such as fog, snow, rain and
sandstorm)

Smart Cruise Control Vehicle-
to-Vehicle Distance
To set Vehicle-to-VehicleDistance
When the Smart Cruise Control System
is ON, you can set and maintain the dis-
tance from the vehicle ahead of you with-
out pressing the accelerator or brake
pedal. Each time the button is pressed, the vehi-
cle to vehicle distance changes as fol-
lows:
For example, if you drive at 56 mph (90
km/h), the distance maintain as follows:
Distance 4 -
approximately 172 feet
(52.5 m)
Distance 3 - approximately 130 feet (40 m)
Distance 2 - approximately 106 feet
(32.5 m)
Distance 1 - approximately 82 feet (25 m)
Information
The distance is set to the last set distance
when the system is used for the first time
after starting the engine.

SCC Front Radar Sensor
The Smart Cruise Control uses a radar to
detect distance to the vehicle ahead.
Warning message
Check SCC radar
When the sensor lens cover is blocked
with dirt, snow, or debris, the Smart
Cruise Control System operation may
stop temporarily. If this occurs, a warning
message will appear on the LCD display.
Remove any dirt, snow, or debris and
clean the radar sensor lens cover before
operating the Smart Cruise Control
System.
The Smart Cruise Control system may
not properly activate, if the radar is total-
ly contaminated, or if any substance is
not detected after turning ON the engine
(e.g. in an open terrain).
OLF054203N
If the vehicle ahead (vehicle speed:
less than 20 mph (30 km/h)) disap-
pears to the next lane, the warning
chime will sound and a message
will appear. Adjust your vehicle
speed for vehicles or objects that
can suddenly appear in front of you
by depressing the brake pedal.
Always pay attention to the road
condition ahead.

Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may have
little or no contact with the road surface
and actually ride on the water. The best
advice is SLOW DOWN when the road is
wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to "Tire Tread" in chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead to
sudden tire failure that may cause loss of
vehicle control resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
i
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Make sure all passengers are
wearing their seat belts.
