Introduction

Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as MMT (Methylcyclopentadi-
enyl Manganese Tricarbonyl).
Kia does not recommend the use of
gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Use of MTBE
Kia recommends avoiding fuels con-
taining MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen
Content 2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0%
vol. (Oxygen Content 2.7% weight)
may reduce vehicle performance and
produce vapor lock or hard starting.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system.
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which helps
prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance of the Emission Control
System. For more information on
TOP TIER Detergent Gasoline,
please go to the website (www
.top-
tiergas.com).
For Customers who do not use TOP
TIER Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If
TOP TIER Detergent Gasoline is not
available, one bottle of additive
added to the fuel tank at 7,500 miles
or every engine oil change is recom-
mended. Additives are available from
your authorized Kia dealer along with
information on how to use them. Do
not mix other additives.
CAUTION
Your New Vehicle Limited Warranty may not cover damageto the fuel system and any per-formance problems that arecaused by the use of fuels con-taining methanol or fuels con-taining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)

Features of your vehicle
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
and other pollutants that come into
the vehicle from the outside through
the heating and air conditioning sys-
tem. If dust or other pollutants accu-
mulate in the filter over a period of
time, the air flow from the air vents
may decrease, resulting in moisture
accumulation on the inside of the
windshield even when the outside
(fresh) air position is selected. If this
happens, have the climate control air
filter replaced by an authorized Kia
dealer.
✽ ✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
The air conditioning system should
be serviced by an authorized Kia
dealer.
CAUTION - Compressor
damage
It is important that the correct
type and amount of oil andrefrigerant is used. Otherwise,damage to the compressor andabnormal system operation mayoccur.

Use high quality ethylene gly-
col 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 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 battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
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
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and igni-
tion system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components 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 heat-
ed 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 instruc-
tions on the container. Window wash-
er 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 fin-
ish.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN 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. If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings.
If the fluid level is excessively low,
have the brake/clutch* system
checked by an authorized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand 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.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

Maintenance
FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment 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.
Before replacing a blown fuse, dis-
connect the negative battery cable.
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: bladetype for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
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 - Fuse replace-
ment
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.
