Safety system of your vehicle
Damaged seat belts and seat
belt assemblies will not operate
properly. Always replace:
•Frayed, contaminated, or dam-
aged webbing.
•Damaged hardware.
•The entire seat belt assembly
after it has been worn in an
accident, even if damage to
webbing or assembly is not
apparent.
WARNING
(Continued)
•No modifications or additions
should be made by the user
which will either prevent the
seat belt adjusting devices
from operating to remove
slack, or prevent the seat belt
assembly from being adjusted
to remove slack.Seat belts are designed to bear
upon the bony structure of the
body, and should be worn low
across the front of the pelvis or
the pelvis, chest and shoulders,
as applicable; wearing the lap
section of the belt across the
abdominal area must be avoid-
ed.
Seat belts should be adjusted as
firmly as possible, consistent
with comfort, to provide the pro-
tection for which they have been
designed.
A slack belt will greatly reduce
the protection afforded to the
wearer.
(Continued)
WARNING (Continued)
Care should be taken to avoid
contamination of the webbing
with polishes, oils and chemi-
cals, and particularly battery
acid. Cleaning may safely be
carried out using mild soap and
water.
The belt should be replaced if
webbing becomes frayed, con-
taminated or damaged. It is
essential to replace the entire
assembly after it has been worn
in a severe impact even if dam-
age to the assembly is not obvi-
ous. Belts should not be worn
with straps twisted. Each seat
belt assembly must only be
used by one occupant; it is dan-
gerous to put a belt around a
child being carried on the occu-
pant's lap.

Charging System
Warning Light
This warning light illuminates:
• Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It remains on until the engine is
started.
• When there is a malfunction with
either the alternator or electrical
charging system.
If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
alternator drive belt for looseness
or breakage.
If the belt is adjusted properly,
there may be a problem in the
electrical charging system.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer as
soon as possible.
Engine Oil Pressure
Warning Light
This warning light illuminates:
• Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It remains on until the engine is
started.
• When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
engine oil level (For more details,
refer to “Engine Oil” in chapter 7).
If the level is low, add oil as required.

able, we recommend that you
have the vehicle inspected by an
authorised HYUNDAI dealer as
soon as possible.

- Engine Oil Pressure
Warning Light
• If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
• If the warning light stays on
whilst the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case:
1. Stop the vehicle as soon as it
is safe to do so.
2. Turn off the engine and check
the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the
warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, we recommend that you
have the vehicle inspected by
an authorised HYUNDAI deal-
er.Low Fuel Level

• Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
• During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristics.System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box, filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
screen even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorised HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorised
HYUNDAI dealer.
Information
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorised
HYUNDAI dealer.Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

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.
