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 ofcoolant 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 coolantin 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
The winter temperature increases
the battery consumption.
Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignitionsystem
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,more frequent oil and filter changesare required.
HSG (Hybrid starter & genera- tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vaporhose or fuel filler cap is correctlyreplaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.

Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-ination. If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized HYUNDAI dealer.
Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
Brake fluid, which has been exposed to open air for an
extended time should NEVER beused as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Do not use the wrong kind of brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).

NOTICE
OLFH074007 If the brake system requires fre-
quent additions of fluid thiscould indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. Ifbrake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediatemedical attention.

Maintenance
Interior care
Interior general precautions
Prevent caustic solutions such as perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Cleaning the upholstery andinterior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-ly maintained.
Leather (if equipped)
Feature of Seat Leather
- Leather is made from the outerskin of an animal, which goes through a special process to be
available for use. Since it is a nat-
ural object, each part differs in
thickness or density.
Wrinkles may appear as a natural result of stretching and shrinking
depending on the temperature
and humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
Using anything but recom-
mended cleaners and proce-
dures may affect the fabric’sappearance and fire-resistant
properties.
CAUTION
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
When cleaning leather prod-
ucts (steering wheel, seats
etc.), use neutral detergents
or low alcohol content solu-
tions. If you use high alcoholcontent solutions or acid/
alkaline detergents, the color
of the leather may fade or the
surface may get stripped off.
CAUTION

Maintenance
Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weakenthe seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory lubrication
in hot weather. Using oils of any viscosity other than those recommended
could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.
