Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Do not spill engine oil when adding or changing engine oil. Wipe off
spilled oil immediately.
The engine oil consumption may increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).
The engine oil consumption can be affected by driving habits, climate
conditions, traffic conditions, oil
quality, etc. Therefore, it is recom-
mended that you inspect the
engine oil level regularly and refill it
if necessary.Changing the engine oil and
filter
If the maintenance schedule toreplace engine oil is exceeded, the
engine oil performance may deteri-
orate, and the engine condition
may be affected. Therefore,
replace the engine oil according to
the maintenance schedule.
To keep the engine in optimal con- dition, use the recommended
engine oil and filter. If the recom-
mended engine oil and filter are
not used replace it according to the
maintenance schedule under
severe usage conditions.
The purpose of the maintenance schedule for engine oil replace-
ment is to prevent oil deterioration
and it is irrelevant to oil consump-
tion. Check and refill engine oil reg-
ularly.

WARNING - Used engine
oil
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with
soap and warm water as soon as
possible after handling used oil.
Do not leave used engine oil
within the reach of children.
CAUTION
The engine oil is very hot imme-
diately after the vehicle has
been driven and can cause
burns during replacement.
Replace the engine oil after the
engine oil has cooled down.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.Periodically check that the fluid level
in the brake fluid reservoir is
between MIN and MAX. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.CAUTION - Proper fluid
Only use brake fluid in brake
system. Small amounts of
improper fluids (such as engine
oil) can cause damage to the
brake system.

ENGINE CLUTCH ACTUATOR FLUID
Checking the engine clutch
actuator fluid level
In normal driving conditions, the
actuator fluid level does not go down
rapidly. However, oil consumption
rate may rise as vehicle mileage
increases, and leakage in actuator
related parts may result in increased
consumption of the engine clutch
actuator oil. Regularly check and
make sure the engine clutch actuator
oil fluid level is between [MIN] and
[MAX] marks.
If the oil level is below [MIN] mark,
we recommend that your vehicle be
checked by an authorized Kia dealer.If the fluid level is excessively low, we
recommend that the system be
checked by an authorized Kia dealer.
Use only the specified engine clutch
actuator fluid.
(Refer to “Recommended lubricants
or capacities” in chapter 8.)
Never mix different types of fluid.
✽ ✽
NOTICE - Loss of engine
clutch actuator fluid
In the event the engine clutch actua-
tor requires frequent additions of
fluid, we recommend that the system
be inspected by an authorized Kia
dealer.
WARNING- Engine clutch
actuator fluid
When changing and adding
engine clutch actuator fluid,
handle it carefully. Do not let it
come in contact with your eyes.
If engine clutch actuator fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh water, and seek medical
attention as soon as possible.

CAUTION
Do not allow engine clutch actu-
ator fluid to contact the vehi-
cle's body paint, as paint dam-
age will result. The engine
clutch actuator fluid that has
been exposed to open air for an
extended time should never be
used as its quality cannot be
guaranteed. It should be proper-
ly disposed. Do not put in the
wrong kind of fluid. A few drops
of mineral-based oil, such as
engine oil, in your engine clutch
actuator system can damage
engine clutch actuator system
parts.

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 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 check-
ing 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
The following items should be reset
after the battery has been dis-
charged or the battery has been dis-
connected.

FUSES
❈Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will melt.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
Do not arbitrarily modify or add-on
electric wiring to the vehicle.
WARNING- Fuse replace-
ment
Never replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly a
fire.
Never install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
