Check battery and cables
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by a
HYUNDAI authorised repairer 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 a
HYUNDAI authorised repairer. Check spark plugs and ignition
system
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
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 a HYUNDAI
authorised repairer, 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.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by a HYUNDAI
authorised repairer.
Spark plugs
(For Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(For Petrol Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by a HYUNDAI authorised
repairer.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses
and connections for leakage and dam-
age. Replace any damaged parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions. We recommend that the
automatic transaxle fluid changed by
a HYUNDAI authorised repairer
according to the maintenance sched-
ule.
Information
Automatic transaxle fluid colour is
basically red. As the vehicle is driven,
the automatic transaxle fluid will begin
to look darker. It is normal condition
and you should not judge the need to
replace the fluid based upon the
changed colour.
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.
