Service in
This mode calculates and displays
when the vehicle needs a scheduled
maintenance service (kilometres or
days).
If the remaining kilometres or time
reaches 1500 km or 30 days,
"Service in" is displayed for several
seconds each time you set the igni-
tion switch or Engine Start/Stop but-
ton to the ON position.
For the setting of the service inter-

• 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.

Chain Installation
When installing tyre chains, follow
the manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 30 km/h) with
chains installed. If you hear the
chains contacting the body or chas-
sis, stop and tighten them. If they still
make contact, slow down until the
noise stops. Remove the tyre chains
as soon as you begin driving on
cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle haz-
ard warning flasher and place a tri-
angular emergency warning device
behind the vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.When using tyre chains:
• Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
• Use SAE “S” class or wire
chains.
• If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
• To prevent body damage,
retighten the chains after driving
0.5~1.0 km.
• Do not use tyre chains on vehi-
cles equipped with aluminium
wheels. If unavoidable, use a
wire type chain.
• Use wire chains less than 12 mm
(0.47 in) wide to prevent damage
to the chain’s connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to ensure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.

Ready to leave after parking on
a hill
1.With the shift lever to P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle), apply your brakes and hold
the brake pedal down whilst you:
• Start your engine;
• Shift into gear; and
• Release the parking brake.
2.Slowly remove your foot from the
brake pedal.
3.Drive slowly until the trailer is clear
of the chocks.
4.Stop and have someone pick up
and store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. If you are planning
a trip with a trailer, it's a good idea to
review these items before you start
your trip. Don't forget to also maintain
your trailer and towbar. Follow the
maintenance schedule that accom-
panied your trailer and check it peri-
odically. Preferably, conduct the
check at the start of each day's driv-
ing. Most importantly, all towbar nuts
and bolts should be tight.To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
• When towing check automatic
transaxle fluid more frequently.
