The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate.
•When the engine overheats from
low engine coolant, suddenly
adding engine coolant may
cause cracks in the engine. To
prevent damage, add engine
coolant slowly in small quanti-
ties.
•Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.

NOTICE
Removing radiator
cap
•Never attempt to remove the
radiator cap whilst the engine
is operating or hot.
Doing so might lead to cooling
system and engine damage
and could result in serious
personal injury from escaping
hot coolant or steam.
•Tu r n t h e e n g i n e o f f a n d w a i t
until it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
anticlockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system.

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) 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 authorised HYUNDAI
dealer.
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 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.

When you are sure all the
pressure has been released,
press down on the cap, using
a thick towel, and continue
turning anticlockwise to
remove it.
•Even if the engine is not oper-
ating, do not remove the radia-
tor cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may still blow out under pres-
sure, causing serious injury.

Maintenance
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-
minium engine parts and must be
protected a phosphate based eth-
ylene-glycol coolant to prevent cor-
rosion 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.
For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the coolant
We recommend that the coolant be
replaced by an authorised HYUNDAI
dealer.
Put a thick cloth or fabric around
the radiator cap before refilling
the coolant in order to prevent the
coolant from overflowing into
engine parts such as the alterna-
tor.
NOTICE
i
•Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
•Engine coolant can severely
obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control or damage to paint
and body trim.

Checking the brake/clutch
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.
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 authorised HYUNDAI
dealer.
Information
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Never mix different types of fluid.
Information
Before removing the brake/clutch
filler cap, read the warning on the cap.
Information
Clean the filler cap before removing.
Use only DOT3 or DOT4 brake/clutch
fluid from a sealed container.

In the event the brake/clutch
system requires frequent addi-
tions of fluid, we recommend
that the system be inspected by
an authorised HYUNDAI dealer.

Maintenance
Do not allow brake/clutch fluid to
contact the vehicle's body paint,
as paint damage will result.
Brake/clutch fluid, which has been
exposed to open air for an extend-
ed 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/clutch system can damage
brake/clutch system parts.
NOTICE
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If brake/
clutch fluid should come in con-
tact 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.

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.
- Coolant
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
NOTICE
OAD075011
•Engine coolant can severely
obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control or damage to paint
and body trim.
•Windscreen 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.
•Windscreen washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windscreen
washer fluid. Serious injury or
death could occur.

Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard whilst fully applying it
from the released position. 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 autho-
rised HYUNDAI dealer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).

Maintenance
Information
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 chapter).
•Do not drive with the air cleaner
filter removed. This will result in
excessive engine wear.
•When removing the air cleaner
filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
•Use HYUNDAI genuine parts,
use of non-genuine parts could
damage the air flow sensor.

Filter inspection
If the vehicle is operated in 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.
Install a new climate control air filter
in the correct direction with the
arrow symbol(↓↓) facing downwards,
otherwise, it may be noisy and the
effectiveness of the filter may be
reduced.
Filter replacement
1.With the glove box open, remove
the stoppers on both sides.
2.Remove the support strap (1).
3.Remove the climate control air fil-
ter case whilst pressing the lock on
the left side of the cover.
4.Replace the climate control air filter.
5.Reassemble in the reverse order of
disassembly.
