the battery consumption.Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary

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
authorized HYUNDAI dealer. Check spark plugs and ignitionsystem
Inspect the spark plugs, as speci-
fied in the 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

being frozen, add authorized window

ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized

most vehicle accessory outlets. Donot use engine coolant or other types
of anti-freeze solution to prevent any
