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. Turn the knob
to the AUTO position when the engine is
running. The adaptive front lighting sys-
tem will operate when the headlamp is
ON. To turn off the AFLS, turn the knob to
the other position. After turning the AFLS
off, headlamp swiveling no longer occurs,
but leveling 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, take your vehicle to
an authorized HYUNDAI dealer and have
the system checked.

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 win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia-
tion.
• 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, have the
exhaust system checked as soon as possible 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.

53
Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside mir-
ror(s), and outside lights are clean.
• Check the condition of the tires.
• 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 sec-
tion 7, “Maintenance”.
Before starting
• Close and lock all doors.
• Position the seat so that all controls are
easily reached.
• Adjust the inside and outside rearview
mirrors.
• Be sure that all lights work.
• Check all gauges.
• Check the operation of warning lights
when the engine start/stop button is
turned to the ON position.
• Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.
BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
vehicle into D (Drive) or R
(Reverse).
WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions 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 driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
Driving while distracted can result in
a loss of vehicle control, that may
lead to an accident, 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 systems which take the
driver’s eyes, attention and focus
away from the safe operation of a
vehicle or which are not permissible
by law should never be used during
operation of the vehicle.

STARTING THE ENGINE
WARNING
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes (high heels, ski
boots, etc.) may interfere with your
ability to use the brake and acceler-
ator pedal.
(Continued)
• Do not place any movable objects
around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an
accident.

59
Driving your vehicle
For smooth operation, depress the brake
pedal when shifting from N (Neutral) to a
forward or reverse gear.Transmission ranges
The indicator in the instrument cluster
displays the shift lever position when the
engine start/stop button is in the ON
position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transmission and prevents the drive
wheels from rotating.
WARNING- Automatic
transmission
• Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting the shift lever into D
(Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movement
can occur if these precautions
are not followed in the order iden-
tified.
CAUTION
• To avoid damage to your trans-
mission, do not accelerate the
engine in R (Reverse) or any for-
ward gear position with the
brakes on.
• When stopped on an incline, do
not hold the vehicle with the
engine power. Use the service
brake or the parking brake.
• Do not shift from N (Neutral) or P
(Park) into D (Drive), or R
(Reverse) when the engine is
above idle speed.
WARNING
• Shifting into P (Park) while the
vehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.
• Do not use the P (Park) position
in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
• Never leave a child unattended in
a vehicle.
CAUTION
The transmission may be damaged
if you shift into P (Park) while the
vehicle is in motion.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
(Continued)
• When descending a long or steep
hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
• Wet brakes may impair the vehi-
cle’s ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
• Always, confirm the position of
the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING- Brakes
• Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
