AFLS (Adaptive Front Lighting
System) (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 posi-
tion 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 positions. After turn-
ing the AFLS off, headlamp swiveling
no longer occurs, but leveling oper-
ates 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 continuously remains on,
we recommend that the system be
checked by an authorized HYUNDAI
dealer.

Daytime running light
(if equipped)
Daytime Running Lights (DRL) can
make it easier for others to see the
front of your vehicle during the day.
DRL can be helpful in many different
driving conditions, and it is especially
helpful after dawn and before sunset.
The DRL system will turn OFF when:
1. The parking light switch is ON.
2. Engine stops.
Headlamp leveling device
It is automatically adjusted the head-
lamp beam level according to the
number of the passengers and the
loading weight in the luggage area.
And it offers the proper headlamp
beam under the various conditions.
Headlamp washer
If your vehicle is equipped with the
headlamp washer it will be operating
at the same time when you operate
the windshield washer. It will operate
when the headlamp switch is in the
first or second position and the
engine start/stop button is in the ON
position.
The washer fluid will be sprayed on
to the headlamps.
✽NOTICE
• Check the headlamp washers peri-
odically to confirm that the wash-
er fluid is being sprayed properly
onto the headlamp lenses.
• The headlamp washer can be
operated 15 minutes after being
operated last time.
WARNING
If it does not work properly even
though your car is inclined
backward according to passen-
ger's posture, or the headlamp
beam is irradiated to the high or
low position, we recommend
that the system be inspected by

minutes, or until the snow and/or ice
is removed before using the wind-
shield wipers to ensure proper oper-
ation.
If you do not remove the snow
and/or ice before using the wiper

wiper and washer system.
Auto control
The rain sensor located on the upper
end of the windshield glass senses
the amount of rainfall and controls
the wiping cycle for the proper inter-
val. The more it rains, the faster the
wiper operates. When the rain stops,
the wiper stops.
To vary the speed setting, turn the
speed control knob (B).

mode when the engine start/stop
button is ON, the wiper will operate
once to perform a self-check of the
system. Set the wiper to OFF (O)

Driving your vehicle
WARNING- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle,
open the windows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death
by asphyxiation.
• Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose.
If you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side
of the car, we recommend that the system be checked by an authorized HYUNDAI dealer.
• Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the
engine in your garage any longer than it takes to start the engine and back the car out.
• Avoid idling the engine for prolonged periods with people inside the car.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an
open area with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn
into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher
speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the
windshield are kept clear of snow, ice, leaves or other obstructions.

• Check under the vehicle for any
sign of leaks.
• Be sure there are no obstacles
behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in section 7,
“Maintenance”.
Before starting
• Close and lock all doors.
• Position the seat so that all con-
trols are easily reached.
• Adjust the inside and outside
rearview mirrors.
• Be sure that all lights work.

Driving while distracted can
result in a loss of vehicle con-
trol, that may lead to an acci-
dent, severe personal injury,
and death. The driver’s primary
responsibility is in the safe and
legal operation of a vehicle, and
use of any handheld devices,
other equipment, or vehicle sys-
tems which take the driver’s

sible by law should never be
used during operation of the
vehicle.

WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is danger-
ous. Drunk driving is the num-
ber one contributor to the high-
way death toll each year. Even a
small amount of alcohol will
affect your reflexes, percep-
tions and judgment. Driving
while under the influence of
drugs is as dangerous or more
dangerous than driving drunk.
You are much more likely to
have a serious accident if you
drink or take drugs and drive.
If you are drinking or taking
drugs, don’t drive. Do not ride
with a driver who has been
drinking or taking drugs.
Choose a designated driver or
call a cab.WARNING
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
putting a vehicle into D (Drive)
or R (Reverse).
WARNING
• When you intend to park or
stop the vehicle with the
engine on, be careful not to
depress the accelerator pedal
for a long period of time. It
may overheat the engine or
exhaust system and cause
fire.
• When you make a sudden
stop or turn the steering
wheel rapidly, loose objects
may drop on the floor and it
could interfere with the opera-
tion of the foot pedals, possi-
bly causing an accident. Keep
all things in the vehicle safely
stored.
• If you do not focus on driving,
it may cause an accident. Be
careful when operating what
may disturb driving such as
audio or heater. It is the
responsibility of the driver to
always drive safely.
