If the gauge pointer moves beyond the
normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the Engine
Overheats" in chapter 6.
Fuel gauge
This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in chap-ter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will illuminate
when the fuel tank is nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
NOTICE
iNOTICE
Running out of fuel can expose
vehicle occupants to danger. You
must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
"E (Empty)" level.
WARNINGNever remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severely burn.
Wait until the engine is cool before
adding coolant to the reservoir.

Driving your vehicle
When the ECO mode is activated:
The acceleration response may beslightly reduced if the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission/dual clutch transmission
may change.
The engine speed may be lower than when driving in NORMAL mode.
The above situations are normal condi-
tions when the ECO mode is activated to
improve fuel efficiency. Limitation of the ECO mode opera-
tion:
Even though ECO mode is selected and
there is no change in the ECO indicator :
When the coolant temperature is low,
ECO mode will be limited until engine
temperature is at normal operating
temperature.
When driving up a hill, ECO mode will be limited to provide better power
when driving uphill.
When driving the vehicle with the auto- matic transmission/ dual clutch trans-
mission gear shift lever in manual shift
mode, ECO mode will be limited
according to the shift position.SPORT mode
SPORT mode manages the
driving dynamics by automat-
ically adjusting the steering
effort, and the engine and
transmission control logic for enhanced
driver performance.
When SPORT mode is selected by pressing the DRIVE MODE button, the
SPORT indicator will illuminate.
Whenever the engine is restarted, the Drive Mode will revert back to NOR-
MAL mode. If SPORT mode is desired,
re-select SPORT mode from the
DRIVE MODE button.
When SPORT mode is activated: - The engine rpm will tend to remainraised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accelerat- ing
Information
In SPORT mode, the fuel efficiency may
decrease.

Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may have
little or no contact with the road surface
and actually ride on the water. The best
advice is SLOW DOWN when the road is
wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to "Tire Tread" in chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead to
sudden tire failure that may cause loss of
vehicle control resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
i
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Make sure all passengers are
wearing their seat belts.

Winter Precautions
Use high quality ethylene glycolcoolant
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 chapter 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in chapter
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Check spark plugs and ignitionsystem
Inspect your spark plugs as described in
chapter 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.
Use approved window washeranti-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 instructions on the con-
tainer. Window washer 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 brakefreeze
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 temporar-
ily 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 inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.

What to do in an emergency
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine may be overheating. If this hap-
pens, you should:
1. Pull off the road and stop as soon asit is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air condi-
tioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle 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 operat-
ing. If the fan is not running, turn the
engine off. 4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (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 tem-
perature has returned to normal.
Then, if coolant has been lost, careful-
ly 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.

While the engine is run-
ning, keep hands, cloth-
ing and tools away from
the moving parts such
as the cooling fan and
drive belt to prevent
serious injury.
WARNING
Your vehicle is
equipped with a pres-
surized coolant reserve
tank. NEVER remove
the coolant reserve tank
cap or the radiator drain plug while
the engine and radiator are HOT.
Hot coolant and steam may blow
out under pressure, causing seri-
ous injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
coolant reserve tank 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.
(Continued)
(Continued)
When you are sure all the pressure
has been released, continue turn-
ing the cap counterclockwise to
remove it.
WARNING
Serious loss of coolant indicates a
leak in the cooling system and
should be checked as soon as pos-
sible by an authorized HYUNDAI
dealer.
