CAUTION
Always be sure to clean the area around
any filler plug, drain plug, or dipstick
before checking or draining any
lubricant. This is especially important
in dusty or sandy areas and when the
vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms that
could be damaged.Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and
cold weather performance, however,
higher viscosity engine oils are required
for satisfactory lubrication in hot
weather.
Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.

NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
Information
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up hills
or in heavy traffic when outside
temperatures are high. Air conditioning
system operation may cause engine
overheating. Continue to use the blower
fan but turn the air conditioning system
off if the temperature gauge indicates
engine overheating.
• When opening the windows in humid
weather, air conditioning may create
water droplets inside the vehicle. Since
excessive water droplets may cause
damage to electrical equipment, air

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO 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 vehicle, 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. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at "Fresh" and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan
control set to high.

Various driving situations, which you may
encounter in SMART mode
• The driving mode automatically
changes to SMART ECO mode after
a certain period of time, when you
gently depress the accelerator pedal
(Your driving is categorized to be
economic.).
• The driving mode automatically
changes from SMART ECO mode to
SMART NORMAL mode after a certain
period of time, when you sharply or
repetitively depress the accelerator
pedal.
• The driving mode automatically
changes to SMART NORMAL mode
with the same driving patterns, when
the vehicle starts to drive on an
upward slope of a certain angle. The
driving mode automatically returns to
SMART ECO mode, when the vehicle
enters a leveled road.
• The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
• You may still sense the engine
braking performance, even when
you release the accelerator pedal in
SMART SPORT mode. It is because
your vehicle remains in lower gear
over a certain period of time for next
acceleration. Thus, it is a normal
driving situation, not indicating any
malfunction. •
The driving mode automatically
changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situations,
the driving mode sets to be either
in SMART ECO mode or in SMART
NORMAL mode.
Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indicator
illuminates in those situations.)
• The cruise control is activated :
The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of Smart Cruise Control system.
(SMART mode is not deactivated
just by activating the cruise control
system.)
• The transmission oil temperature is
either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situations.
However, an extremely high/ low
transmission oil temperature may
temporarily deactivate the SMART
mode, because the transmission
condition is out of normal operation
condition.

Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when
there is an accumulation of snow or
ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.
