ENGINE OIL
Checking 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.

BRAKE/CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch* fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake/clutch* fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch* fluid contamina-
tion.
* if equipped If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings
and/or clutch disc (if equipped). If the
fluid level is excessively low, have the
brake/clutch* system checked by an
authorized Kia dealer.
Use only the specified brake/clutch* fluid.
(Refer to “Recommended lubricants andcapacities” in section 8.)
Never mix different types of fluid.
OTF070008
WARNING - Brake/clutch*
fluid
When changing and adding
brake/clutch* fluid, handle it care-
fully. Do not let it come in contact
with your eyes. If brake/clutch* 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 doc-
tor as soon as possible.
WARNING - Loss of
brake/clutch* fluid
In the event the brake/clutch* sys-
tem requires frequent additions of
fluid, the vehicle should be inspect-
ed by an authorized Kia dealer.
CAUTION
Do not allow brake/clutch* fluid to
contact the vehicle's body paint, aspaint damage will result.
Brake/clutch* fluid, which has beenexposed to open air for an extendedtime should never be used as its quality cannot be guaranteed. Itshould be disposed of properly. Don't put in the wrong kind of fluid.A few drops of mineral-based oil, such as engine oil, in yourbrake/clutch* system can damagebrake/clutch* system parts.

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.

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment 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 indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized Kia dealer.
Three kinds of fuses are used: blade typefor lower amperage rating, cartridge type,and multi fuse for higher amperage rat-ings.
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 aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to remove fuses because it may cause a short circuitand damage the system.

Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly rust
and may develop into a major repair
expense.
✽ ✽NOTICE
If your vehicle is damaged and requires
any metal repair or replacement, be sure
the body shop applies anti-corrosion
materials to the parts repaired or
replaced.
CAUTION
Water washing in the engine com-
partment including high pressurewater washing may cause the fail-ure of electrical circuits located in the engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components insidethe vehicle as this may damagethem.
OJB037800
CAUTION
Wiping dust or dirt off the body with a dry cloth will scratch thefinish.
Do not use steel wool, abrasive cleaners, or strong detergentscontaining highly alkaline orcaustic agents on chrome-platedor anodized aluminum parts. Thismay result in damage to the pro- tective coating and cause discol-oration or paint deterioration.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.

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 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 couldbe damaged.
