Operation Tips
• To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
• Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windscreen. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
• To prevent interior fog on the wind-
screen, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to the
desired temperature.
Air conditioning
HYUNDAI Air Conditioning Systems
are filled with R-134a refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the out-
side air or recirculated air position.
4. Adjust the fan speed control and
temperature control to maintain
maximum comfort.• 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 sal-
vaged vehicle and new replace-
ment MAC evaporators shall be
certified (and labelled) as meet-
ing SAE Standard J2842.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on whilst the vehi-
cle was not in use), recharge it by
slow trickle (charging) for 10 hours.
• If the battery gradually discharges
because of high electric load whilst
the vehicle is being used, recharge
it at 20-30A for 2 hours.When recharging the battery,
observe the following precau-
tions:
•The battery must be removed
from the vehicle and placed in
an area with good ventilation.
•Do not allow cigarettes, sparks,
or flames near the battery.
•Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
•Wear eye protection when
checking the battery during
charging.
(Continued)
WARNING (Continued)
•Disconnect the battery charg-
er in the following order.
1. Turn off the battery charger
main switch.
2. Unhook the negative clamp
from the negative battery
terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
•Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and stop the engine.
•The negative battery cable
must be removed first and
installed last when the battery
is disconnected.

Specifications & Consumer information
Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory 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 tempera-
ture your vehicle will be operated in
before the next oil change. Proceed
to select the recommended oil vis-
cosity from the chart. Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing 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.

*1 : For better fuel economy, it is recommended to use the engine oil of a viscosity
grade SAE 5W-30. However, if the engine oil is not available in your country, select
the proper engine oil using the engine oil viscosity chart.
