If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may
damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to "If the
Engine Overheats" in chapter 6.
CAUTION
Never remove the radiator cap
when the engine is hot. Theengine coolant is under pres-
sure and could severely burn.
Wait until the engine is cool
before adding coolant to the
reservoir.

Engine coolanttemperature warninglight (if equipped)
The warning light illuminates if the
temperature of the engine coolant is
above 248±5.4°F (120±3°C).
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “Overheating” in chap-ter 6.
✽✽ NOTICE
If the engine coolant temperature
warning light illuminates, it indi-
cates overheating that may damage
the engine.
Electric power steer- ing (EPS) systemwarning light
This indicator light comes on after
the ignition key is turned to the ONposition and then it will go out after
the engine is started. This light also comes on when the
EPS is not functioning properly. If it
comes on while driving, have your
vehicle inspected by an authorized
HYUNDAI dealer.
Safe stopping
The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors.
If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with

Active ECO system
Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling the engine and
transaxle. Fuel-efficiency is deter-
mined by the driver's driving habits
and road conditions.
When the Active ECO button is
pressed the ECO indicator (green)
will illuminate to show that the
Active ECO is operating.
When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn
off the system, press the active
ECO button again. If Active ECO is turned off, it will
return to normal mode.
When Active ECO is activated :
Engine sound may change.
Vehicle speed may slightly be reduced.
Air conditioner performance may be affected.
✽✽ NOTICE
Active ECO is designed on the
assumption of light to mild throttle
driving style to control engine and
transaxle in order to optimize fuel
economy. A person with an aggres-
sive throttle driving style may find
the engine performance in Active
ECO on mode to be unsatisfactory,
and thus may not realize any fuel
economy gain. In such an aggressive
driver style case, it would be better
to keep Active ECO off for best fuel
economy. For best results, it is rec-
ommended to compare the perform-
ance of both modes to determine
which is more effective for your
driving style.
Limitation of Active ECO opera- tion
If the following conditions occur while
Active ECO is operating, the effec-
tiveness of the Active ECO may be
limited even though the indicator isstill on.
When coolant temperature is low:
The system will be limited until
engine temperature becomes nor-mal.
When driving up a hill: The system will be limited to gain
power when driving uphill becauseengine torque is required.
When using sports mode:
The system will be limited accord-ing to shift request.

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 ofcoolant 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 coolantin accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in section 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.Change to "winter weight" oil if
necessary In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
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.
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 useengine coolant or other types of anti-
freeze as these may damage thepaint finish.

Parking on hills
Generally, if you have a trailer
attached to your vehicle, you should
not park your vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1.Pull the vehicle into the parkingspace.
Turn the steering wheel in the
direction of the curb (right if head-
ed down hill, left if headed up hill).
2.Shift the vehicle to P (Park).
3.Set the parking brake and shut off the vehicle.
4.Place wheel chocks under the trail- er wheels on the down hill side of
the wheels. 5.Start the vehicle, hold the brakes,
shift to neutral, release the parking
brake and slowly release the
brakes until the trailer chocksabsorb the load.
6.Reapply the brakes and parking brakes.
7.Move the shift lever to P (Park, for automatic transaxle vehicle) or 1st
gear when the vehicle is parked on
a uphill grade and in R (Reverse)
on a downhill (for manual transaxle
vehicle).
8.Shut off the vehicle and release the vehicle brakes but leave the park-
ing brake set.
To prevent engine and/or
transaxle overheating:
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge toensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards “H” (HOT), pull
over and stop as soon as it is
safe to do so, and allow theengine to idle until it cools
down. You may proceed oncethe engine has cooled suffi-
ciently.
You must decide your vehicle
speed according to the trailer
weight and uphill grade.
CAUTION
Do not get out of the vehicle
without the parking brake firmly
set. If you have left the engine
running, the vehicle can move
suddenly. You and others could
be seriously or fatally injured.
WARNING

6-8
If your temperature gauge 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 soonas it is safe to do so.
2.Place the shift lever in P (Park) and set the parking brake. If the air con-
ditioning 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.

What to do in an emergency
While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as thecooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the radiator cap or thedrain plug while theengine 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 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 aresure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

What to do in an emergency
6.If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,carefully add coolant to the reser-
voir 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.

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

Maintenance
The 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.Check the condition and connectionsof 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 reservoirwhen 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, we recommend that you
see an authorized HYUNDAI dealer
for a cooling system inspection.
Recommended engine coolant
When adding coolant, use only
deionized water, distilled water or
soft 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-
based coolant to prevent corrosionand 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 thesolution.
OLMB073005
The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.

Maintenance
For mixing percentage, refer to the
following table:
✽✽NOTICE
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 tempera-
ture ranges of -31°F and higher.
Changing engine coolant
Have coolant changed by an author-
ized HYUNDAI dealer according tothe Maintenance Schedule at the
beginning of this chapter.
Ambient
Temperature Mixture Percentage
(volume)
Antifreeze Water
5°F (-15°C) 35 65
-13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control resulting in an acci-dent.
Engine coolant may also
cause damage to paint and
body trim.
WARNING
To prevent damage to engine
parts, put a thick towel around
the radiator cap before refilling
the coolant to prevent the
coolant from overflowing into
engine parts, such as the gener-
ator.
CAUTION

Maintenance
Canister
Fuel vapors generated inside the fuel tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surgetank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to theemission system.
Vehicle modifications
This vehicle should not be modi-fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-soning.
