warning KIA OPTIMA PLUG-IN HYBRID 2017 Owners Manual

NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
WARNING
•Do not use the compact spare tire(if equipped) for tire rotation.
•Do not mix bias ply and radial plytires under any circumstances.This may cause unusual handlingcharacteristics that could result indeath, severe injury, or propertydamage.
Wheel alignment and tire
balance
The wheels on your vehicle were
aligned and balanced carefully at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your vehicle pulling one way or the other,
the alignment may need to be reset. If you notice your vehicle vibrating
when driving on a smooth road, your wheels may need to be rebalanced.
CAUTION
Improper wheel weights can damageyour vehicle's aluminum wheels. Useonly approved wheel weights.
Tire replacement
06.-
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid band across the tread. This shows there is
less than 1.6 mm (1/16 in.) of tread left
on the tire. Replace the tire when this
happens.
Do not wait for the band to appear across the entire tread before replacing
the tire.

NOTICE
We recommend that when replacing
tires, use the same originally sup‐
plied with the vehicles.
If not, that affects driving perform‐
ance.
CAUTION
When replacing the tires, recheckand tighten the wheel nuts afterdriving about 50 km (31 miles) andrecheck after driving about 1,000 km(620 miles).If the steering wheel shakes or thevehicle vibrates while driving, thetire is out of balance. Align the tirebalance. If the problem is not solved,we recommend that you contact anauthorized Kia dealer.
WARNING
nReplacing tires
(Continued)
(Continued)
To reduce the chance of serious orfatal injuries from an accidentcaused by tire failure or loss of vehi‐cle control:•Replace tires that are worn, showuneven wear, or are damaged.Worn tires can cause loss of brak‐ing effectiveness, steering control,and traction.
•Do not drive your vehicle with toolittle or too much pressure in yourtires. This can lead to uneven wearand tire failure.
•When replacing tires, never mix ra‐dial and bias-ply tires on the samecar. You must replace all tires (in‐cluding the spare) if moving fromradial to bias-ply tires.
•Using tires and wheels other thanthe recommended sizes couldcause unusual handling character‐istics and poor vehicle control, re‐sulting in a serious accident.
(Continued)
(Continued)
•Wheels that do not meet Kia’sspecifications may fit poorly andresult in damage to the vehicle orunusual handling and poor vehiclecontrol.
•The ABS works by comparing thespeed of the wheels. The tire sizeaffects wheel speed. When replac‐ing tires, all 4 tires must use thesame size originally supplied withthe vehicle. Using tires of a differ‐ent size can cause the ABS (Anti-lock Brake System) and ESC (Elec‐tronic Stability Control) to work ir‐regularly.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new wheels are equivalent to the original factory
units in diameter, rim width and offset.
WARNING
A wheel that is not the correct sizemay adversely affect wheel and

this section for additional
information.
Wheel size designation
Wheels are also marked with important
information that you need if you ever have to replace one. The following ex‐
plains what the letters and numbers in
the wheel size designation mean. Example wheel size designation:
7.5JX19
7.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif‐ ferent speed ratings currently being
used for passenger car tires. The speed
rating is part of the tire size designa‐ tion on the sidewall of the tire. This
symbol corresponds to that tire's de‐
signed maximum safe operating speed.
SpeedRatingSymbolMaximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
SpeedRatingSymbolMaximum Speed
Z Above 240 km/h (149
mph)
3. Checking tire life (TIN: Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date, (in‐ cluding the spare tire) should be re‐
placed by new ones. You can find the
manufacturing date on the tire sidewall (possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consist‐ ing of numbers and English letters. The
manufacturing date is designated by
the last four digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and tread
pattern and the last four numbers indi‐ cate week and year manufactured.
For example:
DOT XXXX XXXX 1616 represents that
the tire was produced in the 16th week
of 2016.
WARNING
nTire age
Tires degrade over time, even whenthey are not being used.Regardless of the remaining tread,we recommend that tires be re‐placed after approximately six (6)years of normal service. Heat causedby hot climates or frequent highloading conditions can accelerate theaging process. Failure to follow thiswarning can result in sudden tirefailure, which could lead to a loss ofcontrol and an accident involving se‐rious injury or death.
4. Tire ply composition and material
The number of layers or plies of rub‐
ber-coated fabric in the tire. Tire man‐ ufacturers also must indicate the ma‐
terials in the tire, which include steel,
nylon, polyester, and others. The letter "R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means belted-bias ply construction.

WARNING
nTire temperature
The temperature grade for this tireis established for a tire that is prop‐erly inflated and not overloaded. Ex‐cessive speed, underinflation, or ex‐cessive loading, either separately orin combination, can cause heat build-up and possible sudden tire failure.This can cause loss of vehicle controland serious injury or death.
Low aspect ratio tire (if
equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided for sporty looks.
Because the low aspect ratio tires are
optimized for handling and braking, it
may be more uncomfortable to ride in and there is more noise compare with
normal tires.
CAUTION
Because the sidewall of the low as‐pect ratio tire is shorter than the
(Continued)
(Continued)
normal, the wheel and tire of thelow aspect ratio tire is easier to bedamaged. So, follow the instructionsbelow.-When driving on a rough road oroff road, drive cautiously becausetires and wheels may be damaged.And after driving, inspect tires andwheels.
-When passing over a pothole,speed bump, manhole, or curbstone, drive slowly so that thetires and wheels are not damaged.
-If the tire is impacted, we recom‐mend that you inspect the tirecondition or contact an authorizedKia dealer.
-To prevent damage to the tire, in‐spect the tire condition and pres‐sure every 3,000 km.
CAUTION
•It is not easy to recognize the tiredamage with your own eyes. But ifthere is the slightest hint of tiredamage, even though you cannotsee the tire damage with your owneyes, have the tire checked or re‐placed because the tire damagemay cause air leakage from thetire.
•If the tire is damaged by driving ona rough road, off road, pothole,manhole, or curb stone, it will notbe covered by the warranty.
•You can find out the tire informa‐tion on the tire sidewall.

❈Left side: Normal Right side: Blown
A vehicle’s electrical system is protec‐
ted from electrical overload damage by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the others in the engine com‐ partment near the battery.
If any of your vehicle’s lights, accesso‐
ries, 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, discon‐ nect the negative battery cable.
Always replace a blown fuse with one
of the same rating.
If the replacement fuse blows, this indi‐
cates an electrical problem. Avoid using the system involved and immediately
consult an authorized Kia dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car‐ tridge type, and multi fuse for higher
amperage ratings.
WARNING
nFuse replacement
•Never replace a fuse with anythingbut another fuse of the same rat‐ing.
•A higher capacity fuse could causedamage and possibly a fire.
•Never install a wire or aluminumfoil instead of the proper fuseeven as a temporary repair. It maycause extensive wiring damageand a possible fire.
•Do not arbitrarily modify or add-on electric wiring of the vehicle.
CAUTION
Do not use a screwdriver or any oth‐er metal object to remove fuses be‐cause it may cause a short circuitand damage the system.
Maintenance

If it fits loosely, we recommend that
you consult an authorized Kia dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you
may not need for operating the vehicle,
such as the cigarette lighter fuse.
If the headlights or taillights, stop lights, courtesy lamp, day time running
lights (D.R.L) do not work and the fuses
are OK, check the fuse panel in the en‐ gine compartment. If a fuse is blown, it
must be replaced.

Always, put the fuse switch at the ON
position. If you move the switch to the OFF posi‐
tion, some items such as audio and dig‐
ital clock must be reset and transmitter
(or smart key) may not work properly.
If the fuse switch is in OFF, a warning sign will illuminate on the dashboard.
CAUTION
•Put all switches in ON when driv‐ing.
•If the vehicle remains idle for over1 month, put all switches in OFF toprevent the batteries from beingdischarged.
•Excluding long-term parking forover 1 month, the contact pointsof switches may wear out uponextensive use. Please refrain fromexcessive use of switches.

WARNING
nHID Headlamp (if equipped)
Do not attempt to replace or inspectthe HID headlamp (XENON bulb) dueto electric shock danger. If the lightbulb does not operate, we recom‐mend that you checked an author‐ized Kia dealer.
NOTICE
HID lamps have superior perform‐
ance vs. halogen bulbs. HID lamps
are estimated by the manufacturer
to last twice as long or longer than
halogen bulbs depending on their
frequency of use. They will probably
require replacement at some point in
the life of the vehicle. Cycling the

headlamps on and off more than
typical use will shorten HID lamps
life. HID lamps do not fail in the
same manner as halogen incandes‐
cent lamps. If a headlamp goes out
after a period of operation but will
immediately relight when the head‐
lamp switch is cycled it is likely the
HID lamp needs to be replaced. HID
lamping components are more com‐
plex than conventional halogen bulbs
thus have higher replacement cost.
