Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water.
Bring the level to F (MAX), but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer.
Recommended engine coolant
• When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified 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.
ODH073004
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

Radiator cap
Do not remove the
radiator cap when the
engine and radiator
are hot. Scalding hot
coolant and steam
may blow out under
pressure causing seri-
ous injury.
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.
WARNING
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as generator.
CAUTION

Maintenance
BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.
If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings.If the fluid level is excessively low, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricants
and capacities” in section 8.)
Never mix different types of fluid.
✽NOTICE
Before removing the brake filler
cap, read the warning on the cap.
ODH073006Loss of brake fluid
In the event the brake system
requires frequent additions of
fluid, we recommend that the
system be inspected by an
authorized HYUNDAI dealer.
WARNING
Clean filler cap before remov-
ing. Use only DOT3 or DOT4
brake fluid from a sealed con-
tainer.
WARNING

Maintenance
Brake fluid
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact
with your eyes. If brake fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh tap water. Have your eyes
examined by a doctor as soon
as possible.
WARNING
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result. Brake
fluid, which has been exposed
to open air for an extended time
should never be used as its
quality cannot be guaranteed. It
should be disposed of properly.
Don't put in the wrong kind of
fluid.
A few drops of mineral-based
oil, such as engine oil, in your
brake system can damage
brake system parts.
CAUTION

Maintenance
WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.
Stroke : 3 notchODH073007
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.
•Windshield Washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
•Windshield washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury or
death could occur.

AIR CLEANER
Filter replacement
It must be replaced when necessary,
and should not be washed.
We recommend that you visit an
authorized HYUNDAI dealer to replace
air cleaner filter.Clean the filter by using compressed
air.
Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the
element more often than the usual
recommended intervals. (Refer to
“Maintenance under severe usage
conditions” in this section.)
•Do not drive with the air clean-
er removed; this will result in
excessive engine wear.
•When removing the air clean-
er filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
•We recommend that you use
parts for replacement from an
authorized HYUNDAI dealer.

CLIMATE CONTROL AIR FILTER
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 performing the follow-
ing procedure, and be careful to
avoid damaging other components.
Replace the filter according to the
Maintenance Schedule.
✽NOTICE
Install a new climate control air fil-
ter in the correct direction with the
arrow symbol (
↓) facing downwards.
Otherwise, the climate control effects
may decrease, possibly with a noise.
Filter replacement
1.With the glove box open, remove
the stoppers on both sides.
2.Open the glove box and remove
the support strap (1).3.Remove the climate control air fil-
ter case while pressing the lock on
the left side of the cover.
4.Replace the climate control air fil-
ter.
5.Reassemble in the reverse order of
disassembly.

WIPER BLADES
Blade inspection
✽NOTICE
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
OLMB073019
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
CAUTION
To prevent damage to the wiper
arms or other components, do
not attempt to move the wipers
manually.
CAUTION
The use of a non-specified
wiper blade could result in
wiper malfunction and failure.
