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 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.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. Never attempt to check the Hybrid
High Voltage Battery. The level of charge
in your battery can be checked by an
authorized Kia dealer or a service sta-
tion.
Change to "winter weight" oil if
necessary
In 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.
Check spark plugs and ignition
system
Inspect 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.
To keep locks from freezing
To 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.
Use approved window washer
anti-freeze in system
To 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.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal 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 reinsert 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 - Replace engine
oil
Do not overfill with engine oil.Engine damage may result.

CAUTION
Do not spill engine oil, when addingor changing engine oil. If you drop the engine oil on the engine room,wipe it off immediately.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort 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. When recharging the battery, observe
the following precautions:
The battery must be removed from the
vehicle and placed in an area with
good ventilation.
Watch the battery during charging, and stop or reduce the charging 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 checking the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
Before performing maintenance or recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last when
the battery is disconnected.
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.

Maintenance
Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and defini-
tions
Air Pressure:The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic
transaxle, power seats, and air con-
ditioning.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure:
The amount of
air pressure in a tire, measured in
kilopascal (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
GVWR: Gross Vehicle Weight Rating
GAWR FRT: Gross Axle Weight
Rating for the Front Axle.
GAWR RR: Gross Axle Weight
Rating for the Rear axle.

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 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
operated 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 couldbe damaged.

1. For better fuel economy, it is recommended to use theengine oil of a viscosity grade SAE 5W-20 (API Service SM
/ ILSAC GF-4). However, if the engine oil is not available,
select the proper engine oil using the engine oil viscosity
chart.
