Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON.
CAUTION
Do not operate the engine with-in the tachometer's RED ZONE.This may cause severe enginedamage.
ODM046733
ODM046734WARNING
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could severely burn.
Wait until the engine is cool
before adding coolant to the
reservoir.
CAUTION
If the gauge pointer movesbeyond the normal range areatoward the "H" position, it indi-cates overheating that maydamage the engine.
Do not continue driving with anoverheated engine. If your vehi-cle overheats, refer to "If theEngine Overheats" in chapter 6.

When the ECO mode is activated:
The acceleration response may be
slightly reduced.
The air conditioner performance may be limited.
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the ECO mode is
activated to improve fuel efficiency.
Limitation of the ECO mode oper- ation:
If the following conditions occur while
ECO mode is operating, fuel efficien-
cy may decrease even though there
is no change in the ECO indicator.
When the coolant temperature is low:
Fuel efficiency may decrease until
engine temperature reaches nor-
mal.
When driving up a hill: Fuel efficiency may decrease to
gain performance when driving
uphill because engine torque is
restricted.
When using the automatic transaxle manual shift mode:
Fuel efficiency may decrease
according to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
Fuel efficiency may decrease,
judging that the driver wants to
speed up.
SPORT mode
SPORT mode managesthe driving dynamics by
automatically adjusting the
steering wheel, engine
and transaxle system to
optimize performance.
When the SPORT mode is select- ed by pressing the DRIVE MODE
button, the SPORT indicator (yel-
low color) will illuminate.
Restarting of the engine in the SPORT mode resets the DRIVE
mode to the NORMAL mode. Thus,
when necessary, reselect the
SPORT mode.
When the SPORT mode is activat- ed:
- The RPM (revolutions per min-utes) level is maintained over a
certain length of time, even after
releasing the accelerator pedal.
- When accelerating, up-shifting timing is delayed.
✽ ✽ NOTICE
In the SPORT mode, the fuel effi-
ciency may decrease.

Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling certain engine
and transaxle system operating
parameters. Fuel efficiency depends
on the driver's driving habit and road
condition. 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 will remain on until the Active
ECO button is pressed again.
Active ECO does not turn off when
the engine is restarted. To turn off
Active ECO, press the Active ECO
button again.
If Active ECO is turned off, the sys- tem will return to normal mode.When Active ECO is activated :
The engine noise may get louder.
The vehicle speed may slightly bereduced.
The air conditioner performance may be affected.
Limitation of Active ECO oper-
ation:
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 islow: The system will be limited until
engine performance becomes nor-
mal.
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 sys- tem will be limited according to the
shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds: The system will be limited,
judging that the driver wants to
speed up.

Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.Use high quality ethylene gly-
col 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 cool-
ing system, lubricates 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.
CAUTION
Chains that are the wrong sizeor improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
WARNING- Tire chains
The use of chains may adversely affect vehicle han-
dling.
Do not exceed 20 mph (30 km/h) or the chain manufac-
turer's recommended speed
limit, whichever 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.
WARNING - Mounting
chains
When mounting snow chains,
park the vehicle on level ground
away from traffic. Turn on the
vehicle Hazard Warning flashers
and place a triangular emer-
gency warning device behind
the vehicle if available. Always
place the vehicle in P (Park),
apply the parking brake and
turn off the engine before
installing snow chains.

Parking on hills
Generally, if you have a trailer
attached to your vehicle, you should
not park your vehicle on a hill. People
can be seriously or fatally injured,
and both your vehicle and the trailer
can be damaged if they unexpected-
ly roll down 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 parking
space. Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2. If the vehicle has an automatic transaxle, place the car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer 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 chocks
absorb the load.
6. Reapply the brakes, reapply the parking brake and shift the vehicle
to P (Park) for automatic transaxle.
7. Shut off the vehicle and release the vehicle brakes but leave the
parking brake set.
WARNING- Parking
on a hill
Parking your vehicle on a hill
with a trailer attached could
cause serious injury or death,
should the trailer break loose or
the brake stops working.
CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge toensure the engine does notoverheat.
If the needle of the coolanttemperature gauge movesacross the dial towards "H"(HOT), pull over and stop assoon as it is safe to do so, andallow the engine to idle until itcools down. You may proceedonce the engine has cooledsufficiently.
Use caution when driving on an uphill grade to reduce thepossibility of engine andtransaxle overheating.

What to do in an emergency

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. 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 and set the parking brake. If the air condi-
tioning 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 condition-
ing 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 bro- ken 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
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.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
CAUTION
Serious loss of coolant indi-cates there is a leak in the cool-ing system and this should bechecked as soon as possible byan 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.

ENGINE COOLANT
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 traveling
to a colder climate.
Checking the coolant level
(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 cooling 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 oper- ating, do not remove the radi-
ator 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 temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling
fan) may operate until you dis-
connect the negative battery
cable.
WARNING
Removing radiator
cap
Never attempt to remove the radiator cap while 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.
