Driving your vehicle
E120200AUNUse high quality ethylene glycol
coolantYour 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 cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.E120300AUNCheck battery and cablesWinter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized KIA dealer
or a service station.
E120400AUNChange to "winter weight" oil if
necessaryIn some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized KIA dealer.E120500AUNCheck spark plugs and ignition
systemInspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
E120600AUNTo keep locks from freezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.E120700AUNUse approved window washer
anti-freeze in systemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorized KIA dealer
and most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the paint
finish.

Maintenance
ENGINE OILG060100AEN-EUChecking the engine oil level 1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reachnormal operating temperature. 3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
5. Pull the dipstick out again and check the level. The level should be between
F and L. If it is near or at L, add enough oil to bring
the level to F.
Do not overfill.
Use a funnel to help prevent oil from
being spilled on engine components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci-ties” in section 8.)
WARNING -
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.
CAUTION
Do not overfill with engine oil.Engine damage may result.

✽
✽
NOTICE“C” (COLD) range is for reference only
and should NOT be used to determine
transaxle fluid level.✽ ✽NOTICENew automatic transaxle fluid should be
red. The red dye is added so the assem-
bly plant can identify it as automatic
transaxle fluid and distinguish it from
engine oil or antifreeze. The red dye,
which is not an indicator of fluid quali-
ty, is not permanent. As the vehicle is
driven, the automatic transaxle fluid
will begin to look darker. The color may
eventually appear light brown.
Therefore, have an authorized KIA
dealer change the automatic transaxle
fluid according to the Scheduled
Maintenance at the beginning of this
section.Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in section 8.)
G100200AUNChanging the automatic transaxle
fluidHave automatic transaxle fluid changed
by an authorized KIA dealer according to
the Maintenance Schedule at the begin-
ning of this section.
WARNING -
Transaxle fluid
The transaxle fluid level should be
checked when the engine is at nor-
mal operating temperature. This
means that the engine, radiator,
radiator hose and exhaust system
etc., are very hot. Exercise great
care not to burn yourself during
this procedure.
WARNING
- Parking brake
To avoid sudden movement of the
vehicle, apply parking brake and
depress the brake pedal before
moving the shift lever.
CAUTION
Low fluid level causes transaxle
slippage. Overfilling can causefoaming, loss of fluid and transaxle malfunction.
The use of a non-specified fluid could result in transaxle malfunc-tion and failure.

G190200AUNBattery recharging Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
If the battery gradually discharges because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.
(Continued)
When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cables
are connected.
The electrical ignition system works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.
CAUTION
When you don’t use the vehicle for a long time in the low temper-ature area, separate the batteryand keep it indoors.
Always charge the battery fully to prevent the battery case dam-aged in low temperature area.
WARNING
- Recharging battery
When recharging the battery,
observe the following precautions:
The battery must be removed
from the vehicle and placed in an
area with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charg- ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 49°C (120°F).
Wear eye protection when check- ing the battery during charging.

Specifications, Consumer information
I040100AUN-EURecommended 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 sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-
ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, ordipstick before checking or drain- ing any lubricant. This is especiallyimportant in dusty or sandy areasand when the vehicle is used on unpaved roads. Cleaning the plugand dipstick areas will prevent dirtand grit from entering the engineand other mechanisms that could be damaged.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-
20, 5W-30 (API SL, SM / ILSAC GF-3 or above). However, if the engine oil is not available in
your country, select the proper engine oil using the engine oil viscosity chart.
