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”.
Before starting
• Close and lock all doors.
• Position the seat so that all con-
trols are easily reached.
• Adjust the inside and outside
rearview mirrors.
• Be sure that all lights work.
• Check all gauges.
• Check the operation of warning
lights when the engine start/stop
button is turned to the ON position.

BEFORE DRIVING
WARNING
All passengers must be proper-
ly belted whenever the vehicle
is moving. Refer to “Seat belts”
in section 3 for more informa-
tion on their proper use.
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.

Chain installation
When installing the AutoSock (fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly as you can. Drive slowly with
the AutoSock (fabric snow chain)
installed. If you hear the AutoSock
(fabric snow chain) contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
AutoSock (fabric snow chain) 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.
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.CAUTION
• The AutoSock (fabric snow
chain) that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
• Stop driving and retighten the
AutoSock (fabric snow chain)
any time you hear them hitting
the vehicle.
WARNING - Tire chains
• The use of the AutoSock (fab-
ric snow chain) may adversely
affect vehicle handling.
• Do not exceed 30 km/h (20
mph) or the AutoSock (fabric
snow chain) manufacturer’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 the AutoSock
(fabric snow chain), park the
vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and
place a triangular emergency
warning device behind the vehi-
cle if available. Always place the
vehicle in P (Park), apply the
parking brake and turn off the
engine before installing the
AutoSock (fabric snow chain).

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 soon
as 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 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 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 satis-
factory, 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 the water pump drive belt is bro-
ken or engine coolant is leaking
out, we recommend that you 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,
we recommend that you call an
authorized 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 pre-
vent injury.
CAUTION
• Serious loss of coolant indi-
cates there is a leak in the
cooling system and we recom-
mend that the system be
checked as soon as possible
by an authorized HYUNDAI
dealer.
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of
the opening and cause serious
burns.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
• Check automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

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 level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.Checking the coolant level
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.
• 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.
(Continued)
(Continued)
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.
CAUTION
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
• Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
