Features of your vehicle
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 nor-
mal 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 igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the engine over-
heats” in section 6.
CAUTION
Do not operate the engine with-
in the tachometer's RED ZONE.
This may cause severe engine
damage.
CAUTION
If the gauge pointer moves
beyond the normal range area
toward the “H” position, it indi-
cates overheating that may
damage the engine.

WARNING
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

Features of your vehicle
When the smart key is in the vehi-
cle, if the engine start/stop button
is turned to the ON position, the
indicator will illuminate until the
engine is started. However, when
the smart key is not in the vehicle,
if the engine start/stop button is
depressed, the indicator will blink
for a few minutes to indicate that
you will not be able to start the
engine.
When the ignition switch is turned
to the ON position and the indica-
tor turns off after 2 seconds, the
system may have a problem. Have
the vehicle checked by an author-
ized HYUNDAI dealer.
When the battery is weak, if the
engine start/stop button is
depressed, the indicator will blink
and you will not be able to start the
engine. However, you may still be
able to start the engine by inserting
the smart key in the smart key
holder. If smart key system related
parts have a problem, the indicator
blinks.Low fuel level warning
light
This warning light indicates the fuel
tank is nearly empty. When it comes
on, you should add fuel as soon as
possible. Driving with the fuel level
warning light on or with the fuel level
below “E” can cause the engine to
misfire and damage the catalytic
converter.
Engine coolant tempera-
ture warning light
The warning light shows the temper-
ature of the engine coolant when the
ignition switch is ON.
The warning light illuminates if the
temperature of the engine coolant is
above 248±5.5°F (120±3°C).
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “Overheating” in the
section 6.
✽ ✽
NOTICE
If the engine coolant temperature
warning light illuminates, it indi-
cates overheating that may damage
the engine.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside
mirror(s), and outside lights are
clean.
Check the condition of the tires.
Check under the vehicle for any
sign of leaks.
Be sure there are no obstacles
behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in section 7,
“Maintenance”.CALIFORNIA PROPO-
SITION 65 WARNING
Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.
BEFORE DRIVING
WARNING
Driving while distracted can
result in a loss of vehicle con-
trol, that may lead to an acci-
dent, severe personal injury,
and death. The driver’s primary
responsibility is in the safe and
legal operation of a vehicle, and
use of any handheld devices,
other equipment, or vehicle sys-
tems which take the driver’s
eyes, attention and focus away
from the safe operation of a
vehicle or which are not permis-
sible by law should never be
used during operation of the
vehicle.

547
Driving your vehicle
Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check tires for
proper inflation before driv-
ing. For proper tire pressures,
refer to “Tires and wheels” in
section 8.
Driving on tires with no or
insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, injury, and even death.
Worn-out tires should be
replaced as soon as possible
and should never be used for
driving. Always check the tire
tread before driving your car.
For further information and
tread limits, refer to “Tires and
wheels” in section 7.

Driving your vehicle

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.
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 igni-
tion 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.
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.
CAUTION
Chains that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.
