2017 KIA OPTIMA PLUG-IN HYBRID traction control

Shift-lock override
If the shift lever cannot be moved from
the P (Park) position into R (Reverse) position with the brake pedal de‐
pressed, continue depressing the brake,
then do the following: 1. Place the engine start/stop button switch in the LOCK/OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cover‐ ing the shift-lock release access
hole.
4. Insert a tool (e.g. flathead screw‐ driver) into the access hole andpress down on the tool.
5. Move the shift lever.
6. Remove the tool from the shift- lock override access hole then in‐
stall the cap.
7. We recommend that the system be inspected by an authorized Kia
dealer.
Good driving practices
• Never move the shift lever from P (Park) or N (Neutral) to any other po‐
sition with the accelerator pedal de‐ pressed. • Never move the shift lever into P
(Park) when the vehicle is in motion.
• Be sure the vehicle is completely stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Never take the vehicle out of gear and coast down a hill. This may beextremely hazardous. Always leave
the vehicle in gear when moving.
• Do not "ride" the brakes. This can cause them to overheat and malfunc‐
tion. Instead, when you are driving
down a long hill, slow down and shift to a lower gear. When you do this,
engine braking will help slow down
the vehicle.
• Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
• Always use the parking brake. Do not depend on placing the transaxle in P
(Park) to keep the vehicle from mov‐
ing. • Exercise extreme caution when driv‐
ing on a slippery surface. Be especial‐ly careful when braking, accelerating
or shifting gears. On a slippery sur‐
face, an abrupt change in vehicle
speed can cause the drive wheels to
lose traction and the vehicle to go out of control.
• Optimum vehicle performance and economy is obtained by smoothly de‐
pressing and releasing the accelera‐
tor pedal.
WARNING
•Always buckle-up! In a collision, anunbelted occupant is significantlymore likely to be seriously injuredor killed than a properly belted oc‐cupant.
•Avoid high speeds when corneringor turning.
•Do not make quick steering wheelmovements, such as sharp lanechanges or fast, sharp turns.
•The risk of rollover is greatly in‐creased if you lose control of yourvehicle at highway speeds.

Electronic stability control (ESC)
(if equipped)
0+'
The electronic stability control (ESC)
system is designed to stabilize the ve‐ hicle during cornering maneuvers. ESC
checks where you are steering and
where the vehicle is actually going. ESC applies the brakes at individual wheels
and intervenes with engine manage‐
ment system to stabilize the vehicle.
WARNING
Never drive too fast for the roadconditions or too quickly when cor‐nering. Electronic stability control(ESC) will not prevent accidents. Ex‐cessive speed in turns, abrupt ma‐neuvers and hydroplaning on wetsurfaces can still result in serious ac‐cidents. Only a safe and attentivedriver can prevent accidents byavoiding maneuvers that cause thevehicle to lose traction. Even withESC installed, always follow all thenormal precautions for driving - in‐cluding driving at safe speed for theconditions.
The electronic stability control (ESC)
system is an electronic system de‐ signed to help the driver maintain vehi‐
cle control under adverse conditions. It
is not a substitute for safe driving practices. Factors including speed, road
conditions and driver steering input can
all affect whether ESC will be effective in preventing a loss of control. It is still
your responsibility to drive and corner
at reasonable speed and to leave a suf‐ ficient margin of safety. When you apply your brakes under
conditions which may lock the wheels,
you may hear a L

ESC operation
ESC ON condition
-• When the engine start/stopbutton is turned ON, ESC
and ESC OFF indicator lights
illuminate for approximate‐
ly 3 seconds, then ESC is turned on.
• Press the ESC OFF button for at least half a second
after turning the ignition
ON to turn ESC off. (ESC
OFF indicator will illumi‐
nate). To turn the ESC on, press the ESC OFF button
(ESC OFF indicator light will
go off).
• When starting the engine, you may hear a slight tick‐
ing sound. This is the ESC
performing an automatic
system self-check and does not indicate a problem.
When operating
When the ESC is in operation, ESC indicator light blinks. • When the Electronic Stabili‐ ty Control is operating
properly, you can feel a
slight pulsation in the vehi‐
cle. This is only the effect of brake control and indi‐
cates nothing unusual.
• When moving out of the mud or slippery road, the
engine rpm (revolution per
minute) may not increase
even if you press the accel‐ erator pedal deeply. This is
to maintain the stability
and traction of the vehicle
and does not indicate a
problem.
ESC operation off
ESC OFF state
This car has 2 kinds of ESC off states.If the engine stops when ESC
is off, ESC remains off. Upon
restarting the engine, the ESCwill automatically turn on
again.

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 pos‐
sible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction or tire failure.
NOTICE
Never exceed the maximum tire in‐
flation pressure shown on the tires.
WARNING
•Underinflated or overinflated tirescan cause poor handling, loss ofvehicle control, and sudden tirefailure leading to accidents, inju‐ries, and even death. Always checkthe tires for proper inflation be‐fore driving. For proper tire pres‐sures, refer to L

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

bearing life, braking and stoppingabilities, handling characteristics,ground clearance, body-to-tireclearance, snow chain clearance,speedometer and odometer calibra‐tion, headlight aim and bumperheight.
Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down whenever there is rain, snow or ice on
the road to reduce the possibility of
losing control of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire wear. If you find a tire is worn uneven‐
ly, have your dealer check the wheel
alignment.
When you have new tires installed, make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always be rebalanced if it is removed from the
wheel.
