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.

Before entering vehicle
• Be sure that all windows, outside
mirror(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 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.
• 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
familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING
All passengers must be proper-
ly belted whenever the vehicle
is moving. Refer to “Seat belts”
in section 3 for more informa-
tion on their proper use.
WARNING
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
eyes, attention and focus away
from the safe operation of a
vehicle or which are not permis-
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.

Keep the smart key in the vehicle,
when using the ACC position or if
the vehicle engine is on.
WARNING
The engine will start, only when
the smart key is in the vehicle.
Never allow children or any per-
son who is unfamiliar with the
vehicle to touch the engine
start/stop button or related
parts.
CAUTION
If the engine stalls while you are

N(Neutral) position while the
vehicle is still moving and press
the engine start/stop button in
an attempt to restart 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 accelerator
pedal.
• Do not start the vehicle with the
accelerator pedal depressed.
The vehicle can move and
lead to an accident.
• Wait until the engine rpm is nor-
mal. The vehicle may suddenly
move if the brake pedal is

sion
• Always check the surrounding
areas near your vehicle for
people, especially children,
before shifting a car 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
identified.

Driving your vehicle
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 normally would. The
stopping distance, however, 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
necessary to maintain steering con-
trol on slippery surfaces.
BRAKE SYSTEM
(Continued)
To dry the brakes, apply them
lightly while maintaining a
safe forward speed until brake
performance returns to nor-
mal.
• 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- Brakes
• Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
• When descending a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Continuous
brake application will cause
the brakes to overheat and
could result in a temporary
loss of braking performance.
• Wet brakes may impair the
vehicle’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 fash-
ion after driving through deep
water.
