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 cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. 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 temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station. Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. 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.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution, to
prevent any damage to the vehicle paint.

Maintenance9-14
Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive Belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
Information
When you are inspecting the belt, turn the
engine off.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
Fuel Filter (for gasoline engine)
The fuel filter is considered to be
maintenance free but periodic inspection
is recommended for this maintenance
depends on fuel quality. If there are
some important matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc., replace the fuel
filter immediately. Consult an authorized
HYUNDAI dealer for details.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum Crankcase Ventilation
Hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage.
Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particular
attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to ensure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, to make sure they are
secure, and that no leaks are present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
Air Cleaner Filter
Have the air cleaner filter be replaced by
an authorized HYUNDAI dealer.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the boot
bottom of the ignition coil and the
insulator of the spark plug with a soft
cloth to prevent contamination of the
spark plug insulator.
