Use High-Quality Ethylene Glycol Coolant

Your vehicle is filled with high-quality ethylene glycol coolant in the cooling system. This 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 top up the coolant according to the maintenance schedule in "Cooling System" on page 8-30. Before winter, check the coolant to make sure its freezing point is sufficient for the temperatures expected in winter.

Check the Battery and Cables

Winter places an additional load on the battery system. Visually inspect the battery and cables as described in "Battery" on page 8-53. Have the battery charge level checked by a professional workshop. Kia recommends visiting an authorized Kia dealer/service partner.

Change to "Winter" Oil if Necessary

In some climates, it is recommended that a lower viscosity "winter grade" oil be used in cold weather. See "Recommendations" on page 9-12. If you are not sure which oil grade you should use, Kia recommends consulting an authorized Kia dealer/service partner.

Check the Spark Plugs and Ignition System

Inspect the spark plugs as described in "Spark Plugs (for Gasoline, FFV Engine)" on page 8-30 and replace them if necessary. Also check all ignition wiring and components to make sure they are not cracked, worn or damaged in any way.
