RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

including Semi-synthetic other than API SN plus) is used, then the engine oil and engine oil
filter must be replaced as indicated severe maintenance condition.
*
3 : Use only specified genuine Intelligent Variable Transmission fluid. The use of non-specified
fluid (even marked as compatible with genuine) could result in shift quality deterioration and
vibrations, eventually, the transmission failure.

Vehicle information
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher
viscosity engine oils are required for satisfactory lubrication in hot weather.
Using oils of any viscosity other than those recommended could result in engine
damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended oil
viscosity from the chart.

CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick
before checking or draining any lubricant. This is especially important in dusty or
sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt and grit from entering the engine and other
mechanisms that could be damaged.
An engine oil displaying this American Petroleum Institute(API)
Certification Mark conforms to the International Lubricant
Specification Advisory Committee (ILSAC). It is recommended to only
use engine oils that uphold this API Certification Mark.

Winter precautions
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 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
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 chapter
2 for recommendations. If you aren’t
sure what weight oil you should use, we
recommend that you consult with an
authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described
in chapter 8 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.
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 internally, you may be able
to thaw it out by using a heated key.
Handle the heated key with care to avoid
injury.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of anti-freeze as these may damage the
paint finish.
