Maintenance
For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the engine coolant
We recommend that coolant be
changed by a HYUNDAI authorised
repairer according to the
Maintenance Schedule at the begin-
ning of this chapter.
To prevent damage to engine parts,
put a thick towel around the radiator
cap and/or radiator cap before refill-
ing the coolant to prevent the
coolant from overflowing into
engine parts, such as the alternator.

Maintenance
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals.
• Do not drive with the air cleanerfilter removed. This will result in
excessive engine wear.
• When removing the air cleaner filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
• Use HYUNDAI genuine parts. Use of non-genuine parts could
damage the air flow sensor.
Filter inspection
If the vehicle is operated in the
severely air-polluted cities or on
dusty rough roads for a long period,
it should be inspected more fre-
quently and replaced earlier. When
you, the owner, replace the climate
control air filter, replace it performing
the following procedure, and be care-
ful to avoid damaging other compo-
nents.
Replace the filter according to the
Maintenance Schedule.
