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.
