C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo 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 washer anti-
freeze is available from Hyundai dealers and
most auto parts outlets. Do not use engine
coolant or other types of anti-freeze as these
may damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo 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
heated key with care to avoid injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in Sec-
tion 6 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.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai 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 replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.

CORROSION PREVENTION AND APPEARANCE CARE

CLEANING THE INTERIOR
E040B01A-AATTo Clean the Leather Upholstery
(If Installed)In the normal course of use, leather upholstered
surfaces will, like any material, pick-up dust and
dirt. This dust and dirt must be cleaned off or it
may work into the surface of the leather, caus-
ing damage.
Fine leather needs care, and should be cleaned
when necessary. Washing leather thoroughly
with soap and water will keep your leather
lustrous, beautiful and ensure you have many
years of wear.
Take a piece of cheese cloth and using any mild
soap and lukewarm water, work up a good
lather. Thoroughly wash the leather. Wipe clean
with a slightly damp cloth and dry with soft cloth.
Do this as often as the leather becomes soiled.
During tanning operations, sufficient oils are
incorporated through processing that none need
be applied during the life of the leather. Oil
applied to the finished surface will in no way help
the leather and may do more harm than good.
Varnishes and furniture polishes should never
be used under any conditions.
E040A01A-AATTo Clean the Vinyl UpholsteryTo clean the vinyl upholstery, first remove loose
dirt and dust with a vacuum cleaner. Then apply
a solution of mild soap or detergent and water
using a clean sponge or soft cloth. Allow this to
stay on the surface to loosen the dirt, then wipe
with a clean damp sponge or cloth. If all the dirt
stains are not removed, repeat this procedure
until the upholstery is clean. Do not use gaso-
line, solvent, paint thinner or other strong clean-
ers.
E030E01A-AATMaintaining BumpersSpecial precautions must be observed to pre-
serve the appearance of the bumpers on your
Hyundai. They are:
o Be careful not to spill battery electrolyte or
hydraulic brake fluid on the bumpers. If you
do, wash it off immediately with clean water.
o Be gentle when cleaning the bumper sur-
faces. They are made of soft plastic and the
surface can be damaged if mistreated. Do
not use abrasive cleaners. Use warm water
and mild soap or car-washing solution.
o Do not expose the bumpers to high tem-
peratures. For example, if you have your car
repainted, do not leave the bumpers on the
car if the car is going to be placed in a high-
temperature paint booth.
