Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

7. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper
cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1).If your temperature gage indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park)
and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.

4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
call the nearest authorized
HYUNDAI dealer for assistance.6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance. While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the engine
coolant reservoir tank/radiator
cap or the drain plug while the
engine and radiator are HOT.
Hot coolant and steam may
blow out under pressure, caus-
ing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a towel
or thick rag around it, and turn it
counterclockwise slowly to
release some of the pressure
from the system. Step back
while the pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Maintenance
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized HYUNDAI dealer in
accordance to the scheduled mainte-
nance at the beginning of this chap-
ter.
Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Dual Clutch Transmission
Fluid (if equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).

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 level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.
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.Checking the Engine Coolant
Level
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 the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. 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 for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Never remove the
engine coolant reser-
voir tank/radiator cap
or the drain plug
while the engine and
radiator are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
