4Air conditioning system opera-
tion tips  If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
 To help reduce moisture inside of win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
 During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
 Use the air conditioning system every
month if only for a few minutes to
ensure maximum system perform-
ance.
 When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. 
Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricantWhen the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.✽ ✽
NOTICEWhen the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise, dam-
age to the compressor and abnormal
system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized Kiadealer. Improper service may cause serious injury to the person per-forming the service.

Driving tips25FUEL REQUIREMENTSGasoline engine (unleaded)Your new Kia vehicle is designed to use
only unleaded fuel with a minimum
Octane Rating of 87 Anti-Knock Index
(AKI).✽ ✽NOTICENEVER USE LEADED FUEL. The use
of leaded fuel is detrimental to the cat-
alytic converter and will damage the
engine control system’s oxygen sensor
and affect emission control.
Never add any fuel system cleaning
agents to the fuel tank other than what
Kia has specified. (Consult an
Authorized Kia Dealer for details.)Gasoline containing alcohol and
methanolGasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system. Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
✽ ✽ NOTICENever use gasohol which contains
methanol. Discontinue use of any gaso-
hol product which impairs drivability.
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Warranty &
Consumer Information Manual in your
vehicle.Vehicle modifications This vehicle should not be modified.
Modification of your Kia could affect its
performance, safety or durability, may
violate governmental safety and emis-
sions regulations, and void the vehicle’s
warranty.
In addition, damage or performance
problems resulting from any modification

Driving tips
 Carbon monoxide can be present withother exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
 Do not operate the engine in confined or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
 When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
 Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
 When the engine stalls or fails to start, excessive attempts to re-start the
engine may cause damage to the
emission control system.
Operating precautions for catalytic
converters Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
 Use only UNLEADED FUEL for gaso-line engine (unleaded).
 Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
 Do not misuse or abuse the engine. Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.  Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
 Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized Kia
dealer.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.

contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgement. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or take
drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
