Introduction
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask an authorized KIA dealer whether
leaded gasoline in your vehicle is avail-
able or not. Octane Rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol andmethanol
Gasohol, 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 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 drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the useof:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
WARNING
• Do not "top off" after the nozzle automatically shuts off when refueling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and willdamage the engine control sys-tem’s oxygen sensor and affect emission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consult anauthorized KIA dealer for details.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any
gasohol product which impairs dri-vability.

Features of your vehicle
When leaving your keys with a parking lot
attendant or valet, perform steps 1 to 4
above, remove the mechanical key from
the smart key and leave the smart key
with the attendant. In this manner the
smart key can only be used to start the
engine and operate door locks.
Lock release
To release the trunk lock feature, open
the glove box with the mechanical key
and set the trunk lid control button to ON
position (pressed). In this position the
trunk will open with the trunk lid button or
smart key.Immobilizer system (if equipped)
Your vehicle may be equipped with an
electronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid or not.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.
WARNING
- Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition switch. Children copy
adults and they could place the key
in the ignition switch. The ignition
key would enable children to oper-
ate power windows or other con-
trols, or even make the vehicle
move, which could result in serious
bodily injury or even death. Never
leave the keys in your vehicle with
unsupervised children.
WARNING
Use only KIA original parts for the
ignition key in your vehicle. If an
aftermarket key is used, the ignition
switch may not return to ON after
START. If this happens, the starter
will continue to operate causing
damage to the starter motor and
possible fire due to excessive cur-rent in the wiring.

(Continued)
Do not get back into a vehicle
once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
When using an approved portable fuel container, be sure toplace the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling has
begun, contact with the vehicleshould be maintained until the
filling is complete.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warnings at the gas station facility.
Before refueling note the location of the Emergency Gasoline Shut-
Off, if available, at the gas station
facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.
(Continued)(Continued)Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced byelectrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure thefiller cap and filler door are
securely closed, before starting
the engine.
DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.

Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. If the engine is off or if the power
steering system becomes inoperative,
the vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized KIA dealer.✽✽
NOTICE
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase.
✽
✽ NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below
-10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-
utes to warm up the fluid.
Tilt steering
Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
CAUTION
Never hold the steering wheel to the
extreme right or left for more than 5seconds with the engine running.Holding the steering wheel for more than 5 seconds in either position
may cause damage to the powersteering pump.
WARNING
Never adjust the angle of the steering wheel while driving. You
may lose steering control and
cause severe personal injury,death or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.
