Introduction
Other fuels
Using fuels such as
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) containedfuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained fuels,
may cause vehicle and engine dam-
age.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate or cause plug-
ging, misfiring, poor acceleration,
engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion, etc.
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.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle
performance and damage components
of the fuel system, engine control sys-
tem and emission control system.
✽ ✽

NOTICE
Your New Vehicle Limited
Warranty may not cover damage to
the fuel system and any perform-
ance problems that are caused by
the use of fuels containing methanol.
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 avail-
able, one bottle of additive added to
the fuel tank at 7,500 miles or every
engine oil change is recommended.
Additives are available from your
authorized Kia dealer along with
information on how to use them. Do
not mix other additives.

Driving your vehicle
Be sure the exhaust system
does not leak.
The exhaust system should be
checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change
in the sound of the exhaust or if you
drive over something that strikes the
underneath side of the vehicle, have
the exhaust system checked as soon
as possible by an authorized Kia
dealer.
WARNING - Engineexhaust
Do not inhale exhaust fumes or
leave your engine running in an
enclosed area for a prolonged
time.
Exhaust fumes contain carbon
monoxide, a colorless, odorless
gas that can cause uncon-
sciousness and death by
asphyxiation.
WARNING - Open trunk
Do not drive with the trunk
open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at
"Floor" or "Face" and the fan
at the highest speed.WARNING - California

Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.

Driving your vehicle

Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are
clean.
Check the condition of the tires.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in chapter 7,
“Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all con-trols are easily reached.
Buckle your seat belt.
Adjust the inside and outside rearview mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights when the ignition switch is
turned to the ON position.
Release the parking brake and make sure the brake warning light
goes off.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING - Distracted driving
Focus on the road while driving.
The driver's primary responsi-
bility is in the safe and legal
operation of the vehicle. Use of
any hand held devices, other
equipment or vehicle systems
that distract the driver should
not be used during vehicle
operation.
WARNING - Check surrounding
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
putting a vehicle into D (Drive)
or R (Reverse).

Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
WARNING - Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out
tires should be replaced as
soon as possible. For further
information and tread limits,
refer to "Tires and wheels" in
chapter 7.
WARNING - Under/Over Inflated Tires
Always check the tires for prop-
er inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.

What to do in an emergency
46
IF THE ENGINE WILL NOT START
If the engine doesn't turn over
or turns over slowly
1.If your vehicle has an automatictransaxle, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2.Check the battery connections to be sure they are clean and tight.
3.Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is dis-
charged.
4.Check the starter connections to be sure they are securely tight-
ened.
5.Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1.Check fuel level.
2.With the ignition switch in theLOCK position, check all connec-
tors at the ignition coil and spark
plugs. Reconnect any that may be
disconnected or loose.
3.Check the fuel line in the engine compartment.
4.If the engine still does not start, call an authorized Kia dealer or seek
other qualified assistance.
WARNING - Push/pull
start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.
