2011 KIA Optima fuel cap

13
Introduction
Your new KIA vehicle is designed to use
only unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.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 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 drivability 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. "E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
KIA recommends that customers do not
use fuel with an ethanol content exceed-
ing 10 percent.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning
agents to the fuel tank other than what has been specified. (Consultan authorized KIA dealer fordetails.)
WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.

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 to
place 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 vehicle
should 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 atthe 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)
Gasoline vapors are dangerous.Before refueling, always stop the
engine and never smoke or allow
sparks and open flames near the
filler area.
Never operate your vehicle with- out a filler cap properly installed,
flammable vapors and gasoline
could leak out in dangerous situ-
ations such as a collision or
rollover. If the filler cap must be
replaced, only use genuine KIA
replacement parts.
Tighten the cap until it clicks one time, otherwise the " "light will
illuminate.

(Continued)
If a fire breaks out during refuel-ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.(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 by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler 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.
(Continued)CAUTION
Make sure to refuel your vehicleaccording to the "Fuel require-ments" suggested in section 1.
If the fuel filler cap requires replacement, use only a genuineKIA cap or the equivalent speci-fied for your vehicle. An incorrect fuel filler cap can result in a seri-ous malfunction of the fuel sys- tem or emission control system.
Do not spill fuel on the exterior surfaces of the vehicle. Any typeof fuel spilled on painted surfacesmay damage the paint.
After refueling, make sure the fuel cap is installed securely to pre-vent fuel spillage in the event ofan accident.

The tachometer pointer may move slight-
ly when the ignition switch is in ACC or
ON position with the engine OFF. This
movement is normal and will not affect
the accuracy of the tachometer once the
engine is running.
Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank. The fuel tank capacity is given in
section 8. The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
CAUTION
Do not operate the engine within
the tachometer's RED ZONE. This may cause severe engine damage.

WARNING- Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with extremely lowfuel level. Running out of fuel couldcause the engine to misfire, damag- ing the catalytic converter.

Driving your vehicle
Certification label
The certification label is located on
the driver's door sill at the center pil-
lar.
This label shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and
cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).
To find out the actual loads on your
front and rear axles, you need to go
to a weigh station and weigh your
vehicle. Your dealer can help you with
this. Be sure to spread out your load
equally on both sides of the center-
line.The label will help you decide how
much cargo and installed equipment
your vehicle can carry.
If you carry items inside your vehicle
- like suitcases, tools, packages, or
anything else - they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash,
the items will keep going and can
cause an injury if they strike the driv-
er or a passenger.
WARNING -Over loading
Never exceed the GVWR for your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weigh-
ing the items (or people)
before putting them in the
vehicle. Be careful not to over-
load your vehicle.
Do not load your vehicle any heavier than the GVWR, either
the maximum front or rear
GAWR and vehicle capacity
weight. If you do, parts,
including tires on your vehicle
can break, and it can change
the way your vehicle handles
and braking ability. This could
cause you to lose control and
crash. Also, overloading can
shorten the life of your vehi-
cle.

Driving your vehicle
This section will guide you in the proper
loading of your vehicle and/or trailer, to
keep your loaded vehicle weight within its
design rating capability, with or without a
trailer. Properly loading your vehicle will
provide maximum return of the vehicle
design performance. Before loading your
vehicle, familiarize yourself with the fol-
lowing terms for determining your vehi-
cle's weight ratings, with or without a
trailer, from the vehicle's specifications
and the compliance label:
Base curb weight
This is the weight of the vehicle including
a full tank of fuel and all standard equip-
ment. It does not include passengers,
cargo, or optional equipment.
Vehicle curb weight
This is the weight of your new vehicle
when you picked it up from your dealer
plus any aftermarket equipment.
Cargo weight
This figure includes all weight added to
the Base Curb Weight, including cargo
and optional equipment.GAW (Gross axle weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
curb weight and all payload.
GAWR (Gross axle weight rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the compliance label.
The total load on each axle must never
exceed its GAWR.
GVW (Gross vehicle weight)
This is the Base Curb Weight plus actual
Cargo Weight plus passengers.
GVWR (Gross vehicle weight rating)
This is the maximum allowable weight of
the fully loaded vehicle (including all
options, equipment, passengers and
cargo). The GVWR is shown on the cer-
tification label located on the driver’s
door sill.
We do not recommend using this
vehicle for trailer towing.
