Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (Full) and L (Low) marks on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (Full), but do not overfill. If fre-
quent additions are required, see an
authorized HYUNDAI dealer for a cooling
system inspection.
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.(Continued)
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the negative battery cable.OYF079005

For mixture percentage, refer to the fol-
lowing table.Changing the coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
WARNING
Radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
CAUTION
Put a thick cloth around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into engine parts such
as the generator.
WARNING -Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.

Maintenance
CAUTION
• Do not drive with the air cleaner
removed; this will result in exces-
sive engine wear.
• When removing the air cleaner fil-
ter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
• Use a HYUNDAI genuine part. Use
of non-genuine parts could dam-
age the air flow sensor.

CLIMATE CONTROL AIR FILTER (IF EQUIPPED)
Filter inspection
If the vehicle is operated in the severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and replaced
earlier. When you, the owner, replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Replace the filter according to the main-
tenance Schedule.
Filter replacement
1. Open the glove box and remove the
support strap (1).2. With the glove box open, remove the
stoppers by turning them counter-
clockwise on both sides.

3. Remove the climate control air filter
cover while pressing the lock on the
right side of the cover.4. Replace the climate control air filter.
5. Reassemble in the reverse order of
disassembly.
✽NOTICE
When replacing the climate control air
filter install it properly. Otherwise, the
system may produce noise and the effec-
tiveness of the filter may be reduced.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
• If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.
• Auto up/down window (See section 4)
• Sunroof (See section 4)
• Driver position memory system
(See section 4)
• Trip computer (See section 4)
• Climate control system
(See section 4)
• Clock (See section 4)
• Audio (See section 4)
WARNING
• Before performing maintenance
or recharging the battery, turn off
all accessories and stop the
engine.
• The negative battery cable must
be removed first and installed
last when the battery is discon-
nected.
• Operation related to the battery
should be done in an authorized
HYUNDAI dealer.
CAUTION
• Keep the battery away from water
or any liquid.
• For your safety, use the authentic-
ity by approved authorized
HYUNDAI dealer, when you
replace the battery.
WARNING- Recharging
battery
When recharging the battery,
observe the following precautions:
• The battery must be removed
from the vehicle and placed in an
area with good ventilation.
• Do not allow cigarettes, sparks,
or flame near the battery.
• Watch the battery during charg-
ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 49°C (120°F).
(Continued)
(Continued)
• Wear eye protection when check-
ing the battery during charging.
• Disconnect the battery charger 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.

Maintenance
Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.Tire rotation
To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
WARNING
• Inspect your tires frequently
for proper inflation as well as
wear and damage. Always use
a tire pressure gauge.
• Tires with too much or too little
pressure wear unevenly caus-
ing poor handling, loss of vehi-
cle control, and sudden tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the tire label located on the dri-
ver's side center pillar.
• Worn tires can cause acci-
dents. Replace tires that are
worn, show uneven wear, or
are damaged.
• Remember to check the pres-
sure of your spare tire.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tires on your vehi-
cle.
