Use high quality ethylene glycol coolant
Your vehicle 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 cooling system, lubricates the water pump, and prevents freezing. Be sure to replace or replenish your coolant in accordance with the maintenance schedule in Chapter 9. Before winter, have your coolant tested to make sure that its freezing point is sufficient for the temperatures anticipated during the winter.
Check battery and cables
Winter temperatures may affect the battery performance. Inspect the battery and cables, as specified in Chapter 9. The battery charging level can be checked by an authorized HYUNDAI dealer or in a service station.
Change to “winter weight” oil if necessary
In some regions in winter, it is recommended to use the “winter weight” oil with lower viscosity. In addition, replace the engine oil and filter if it is close to the next maintenance interval. Fresh engine oil ensures optimum engine operation during the winter months. For more information, refer to Chapter 10. When you are not sure about a type of winter weight oil, contact an authorized HYUNDAI dealer.
Check spark plugs and ignition system
Inspect the spark plugs, as specified in Chapter 9. If necessary, replace them. Also check all ignition wirings and components for any cracks, wear, and damage.
To prevent locks from freezing
Spray approved de-icing fluid or glycerin into key holes. When a lock opening is already covered with ice, spray approved de-icing fluid over the ice to remove it. When an internal part of a lock freezes, try to thaw it with a heated key. Carefully use the heated key to avoid an injury.
Use approved window washer antifreeze solution
Add window washer anti-freeze solution, as specified on the window washer container. Window washer anti-freeze solution is available from an authorized HYUNDAI dealer, and most vehicle accessory outlets.
NOTICE
Do not use engine coolant or other types of anti-freeze solution, to prevent any damage to the vehicle paint.
Do not let your parking brake freeze
Under some conditions, your parking brake may freeze in the engaged position. This is most likely to happen when there is an accumulation of snow or ice around or near the rear brakes or the brakes are wet. When there is the risk that your parking brake may freeze: temporarily apply the parking brake with the gear in P (Park), then block the rear wheels, and then release the parking brake.
Do not let ice and snow accumulate underneath
Under some conditions, snow and ice may build up under the fenders and interfere with the steering. When driving in such conditions during the severe winter, check underneath the vehicle on a regular basis, to make sure that the front wheels and the steering components are not blocked.
Carry emergency equipment
In accordance with weather conditions, carry appropriate emergency equipment, while driving. Some of the items you may want to carry include tire chains, tow straps or chains, flashlight, emergency flares, sand, shovel, jumper cables, window scraper, gloves, ground cloth, coveralls, blanket, etc.
Do not place objects or materials in the engine compartment
Putting objects or materials in the engine compartment may cause an engine failure or a fire, because they may block the engine cooling. Such damage is not covered by the manufacturer’s warranty.
Drive your vehicle when water vapor condenses and accumulates inside the exhaust pipes
When the vehicle is stopped for a long time in winter while the engine is running, water vapor may condense and accumulate inside the exhaust pipes. Water in the exhaust pipes may cause noise, etc., but it is drained driving at medium to high speed.
