Driving your vehicle
Use wire chains less than 12 mm
wide to prevent damage to the
chain’s connection.
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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. 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 temperatures affect battery
performance.Inspect the battery
and cables, as specified in the
chapter 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.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 chapter
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.

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.

*2: Engine oils labelled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reduc-
ing 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.

Refer to “Fuel Requirements” in the Introduction chapter.
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.
CAUTION
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 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.

Specifications & Consumer information
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 recommend-
ed 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 proper engine oil using the engine oil
viscosity chart.
