C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening.

Handle the heated key with careto avoid burning your fingers. NOTE: The proper temperature for using the immobilizer key is from -40°C to 80°C. If you heat the immobilizerkey over 80°C to open the frozenlock, it may cause damage to thetransponder in its head.
C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethylene glycol coolant in thecooling system. It is the only type of coolant that should be used because it helps prevent corrosion in the coolingsystem, lubricates the water pump andprevents freezing. Be sure to replaceor replenish your coolant in accor-dance with the maintenance schedule in Section 5. Before winter, have your coolant tested to assure that its freez-ing point is sufficient for the tempera-tures anticipated during the winter.
