AFLS (Adaptive Front LightingSystem) a.k.a. DBL (DynamicBending Light) (if equipped)
Adaptive front lighting system uses the
steering angle and vehicle speed, to
keep your field of vision wide by swiveling
and leveling the headlamp.
Change the switch to the AUTO position
when the engine is running. The adaptive
front lighting system will operate when
the headlamp is ON. To turn off the
AFLS, change the switch to other posi-
tions. After turning the AFLS off, head-
lamp swiveling no longer occurs, but lev-
eling operates continuously.
If the AFLS malfunction indicator comes
on, the AFLS is not working properly. Drive to the nearest safe location and
restart the engine. If the indicator contin-
uously remains on, we recommend that
the system be checked by an authorized
HYUNDAI dealer.
Interior Lights
Do not use the interior lights for
extended periods when the engine is
turned off or the battery will dis-
charge.
Interior lamp AUTO cut
The interior lamps will automatically go
off approximately 20 minutes after the
engine is turned off and the doors
closed. If a door is opened, the lamp will
go off 40 minutes after the engine is
turned off. If the doors are locked by the
remote key or smart key and the vehicle
enters the armed stage of the theft alarm
system, the lamps will go off five seconds
later.

Driving your vehicle
Check the Parking Brake
Warning Light by placing
the ignition switch to the
ON position (do not start
the engine).
This light will be illuminat-
ed when the parking brake is applied with
the ignition switch in the START or ON
position.
Before driving, be sure the parking brake
is released and the Brake Warning Light
is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while engine is running, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion.Anti-lock Brake System (ABS)
ABS is an electronic braking system that
helps prevent a braking skid. ABS allows
the driver to steer and brake at the same
time.
An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not pre-
vent accidents due to improper or
dangerous driving maneuvers.
Even though vehicle control is
improved during emergency brak-
ing, always maintain a safe dis-
tance between you and objects
ahead of you. Vehicle speeds
should always be reduced during
extreme road conditions. The brak-
ing distance for cars equipped with
ABS or ESC may be longer than for
those without these systems in the
following road conditions.
Drive your vehicle at reduced
speeds during the following condi-
tions:
Rough, gravel or snow-covered
roads.
On roads where the road surface
is pitted or has different surface
height.
Tire chains are installed on your
vehicle.
(Continued)
WARNING
(Continued)
The safety features of an ABS or
ESC equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

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.

that the brake switch is operating nor-
mally. Depress the brake pedal at least
once after turning ON the ignition or

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
