Features of your vehicle
Tachometer
The tachometer indicates the approxi-
mate number of engine revolutions per
minute (rpm).
Use the tachometer to select the correct
shift points and to prevent lugging and/or
over-revving the engine.When the door is open, or if the engine is
not started within 1 minute, the tachometer
pointer may move slightly in ON position
with the engine OFF. This movement is
normal and will not affect the accuracy of
the tachometer once the engine is running.
Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
OMD040048N
CAUTION
If the gauge moves beyond the nor-
mal range area toward the “H” posi-
tion, it indicates overheating that
may damage the engine.
CAUTION
Do not operate the engine within
the tachometer's RED ZONE.
This may cause severe engine dam-
age.

Driving your vehicle
Active ECO operation
Active ECO helps improve fuel efficiency
by controlling the engine and transaxle.
But fuel-efficiency can be changed 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 but-
ton again.
If Active ECO is turned off, it will return
to the normal mode.
Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
When the coolant temperature is low:
The system will be limited until engine
performance becomes normal.
When driving up a hill: The system will
be limited to gain power when driving
uphill because the engine torque is
restricted.
When using sports mode: The system
will be limited according to the shift
location.
When the accelerator pedal is deeply
pressed for a few seconds: The system
will be limited, judging that the driver
wants to speed up.

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 of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in 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 bat-
tery 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 compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING- Tire chains
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h)
or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps,
holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked-
wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.

What to do in an emergency
6 6
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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 (automatic
transaxle) or neutral (manual transaxle)
and set the parking brake. If the air con-
ditioning is on, turn it off.
3. If engine coolant is running out under
the car or steam is coming 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 to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is broken
or 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 tem-
perature has returned to normal. 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 overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized
HYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This may
result in coolant being blown out of
the opening and cause serious
burns.

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 and 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. Bring the level
to F, but do not overfill. If frequent addi-
tions are required, see an authorized
HYUNDAI dealer for a cooling system
inspection.
OMD070004N
(Continued)
Turn the engine off and wait until it
cools down. Use extreme care
when removing 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 cool-
ing system. When you are sure all
the pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
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
(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 tem-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition.

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 aluminum
engine parts and must be protected by
an ethylene-glycol-based coolant to pre-
vent corrosion and freezing.
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.
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.
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.
OMD070005N-1
CAUTION
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 generator.
