Check battery and cables
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in chapter 7.The battery charg-
ing level can be checked by an
authorised HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorised HYUNDAI dealer.Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, 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
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

2: Engine oils labelled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.Lubricant Volume Classification

Recommended SAE viscosity
number
Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage.a
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing 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.
CAUTION
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.
*1: For better fuel economy, it is recommended to use the engine oil of a viscosity grade
SAE 5W-30. However, if the engine oil is not available in your country, select the prop-
er engine oil using the engine oil viscosity chart.
*
2: For better fuel economy, it is recommended to use the engine oil of a viscosity grade
SAE 5W-20.
