Driving your vehicle
- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47
inch (12 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
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 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 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 if
necessary
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 battery 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 ignition
system
Inspect your spark plugs as
described in chapter 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.
Use approved window washer
anti-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 instruc-
tions on the container. Window wash-
er 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 brake
freeze
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 temporarily 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 interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

What to do in an emergency
6
4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (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
temperature has returned to nor-
mal. 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 overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
While the engine is running,
keep hands, clothing 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
pressurized
coolant reserve
tank. NEVER
remove the
engine coolant
reservoir
tank/radiator cap or the drain
plug while the engine and radia-
tor are HOT. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator 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.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid
level.
Check the 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 if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
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 the intelligent variable trans-
mission (IVT) P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the engine
coolant reservoir.
Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer a fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function. Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Maintenance
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Intelligent Variable
Transmission (IVT) Fluid
(if equipped)
Intelligent Variable Transmission
(IVT) Fluid should not be checked
under normal usage conditions. But,
the Intelligent Variable Transmission
(IVT) Fluid should be changed under
severe usage conditions. We recom-
mend that the Intelligent Variable
Transmission (IVT) Fluid changed by
an authorized HYUNDAI dealer
according to the maintenance sched-
ule.
(Refer to "Maintenance Under
Severe Usage Conditions" in this
chapter.)
Intelligent variable transmission
(IVT) fluid color is basically light
amber.
As the vehicle is driven, the intelli-
gent variable transmission (IVT)
fluid will begin to look darker. This
is a normal condition and you
should not judge the need to
replace the fluid based upon the
changed color.
NOTICE
The use of non-specified fluid
(even marked as compatible
with genuine) could result in
shift quality deterioration and
vibrations, and eventual trans-
mission failure.
Use only specified Intelligent
Variable Transmission (IVT)
fluid. (Refer to "Recommended
lubricants and capacities" in
chapter 8.)

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 Engine Coolant
Level
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the F and the 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 to bring the
level to the F mark, but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.

Maintenance
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 mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
- 31°F and higher.
