Use High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high qual-
ity 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 sched-
ule in Section 5. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures an-
ticipated during the winter.

Check Battery and Cables
Winter 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 ser-
vice station.
C160E01A-AAT
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 Section 9 for
recommendations. If you aren't sure what
weight oil you should use, consult your
Hyundai dealer.

Check Spark Plugs and Ignition
System
Inspect your spark plugs as described in
Section 6 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked, worn
or damaged in any way.

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 inter-
nally, you may be able to thaw it out by
using a heated key. Handle the heated key
with care to avoid injury.
NOTE:
The proper temperature for using the
immobilizer key is from -40°F (-40°C) to
176°F (80°C). If you heat the immobilizer
key over 80°C to open the frozen lock, it
may cause damage to the transponder
in its head.
