2017 KIA OPTIMA PLUG-IN HYBRID brakes

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.

BRAKE SYSTEM
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through nor‐ mal usage.
If the hybrid system is not on or is
turned off while driving, the power as‐
sist for the brakes will not work. You can still stop your vehicle by applying
greater force to the brake pedal than
typical. The stopping distance, however,will be longer than with power brakes.
When the hybrid system is not on, the reserve brake power is partially deple‐
ted each time the brake pedal is ap‐
plied. Do not pump the brake pedal when the power assist has been inter‐
rupted.
Pump the brake pedal only when nec‐
essary to maintain steering control on slippery surfaces.
WARNING
nBrakes
(Continued)
(Continued)
•Do not drive with your foot restingon the brake pedal. This will createabnormal high brake tempera‐tures, excessive brake lining andpad wear, and increased stoppingdistances.
•When descending a long or steephill, shift to a lower gear and avoidcontinuous application of thebrakes. Continuous brake applica‐tion will cause the brakes to over‐heat and could result in a tempo‐rary loss of braking performance.
•Wet brakes may impair the vehi‐cle’s ability to safely slow down;the vehicle may also pull to oneside when the brakes are applied.Applying the brakes lightly will in‐dicate whether they have been af‐fected in this way.Always test your brakes in thisfashion after driving through deepwater. To dry the brakes, applythem lightly while maintaining asafe forward speed until brakeperformance returns to normal.
(Continued)
(Continued)
•Always confirm the position of thebrake and accelerator pedal beforedriving. If you don’t check the posi‐tion of the accelerator and brakepedal before driving, you may de‐press the accelerator instead ofthe brake pedal. It may cause a se‐rious accident.
NOTICE
Do not depress the brake pedal con‐
tinuously without the "" indicator
ON. The battery may be discharged.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear a high-pitched warning sound from your
front brakes or rear brakes (if equip‐
ped). You may hear this sound come and go or it may occur whenever you
depress the brake pedal.

Driving your vehicle

Please remember that some driving
conditions or climates may cause a brake squeal when you first apply (or
lightly apply) the brakes. This is normal
and does not indicate a problem with your brakes.
CAUTION
•To avoid costly brake repairs, donot continue to drive with wornbrake pads.
•Always replace the front or rearbrake pads as pairs.
WARNING
nBrake wear
This brake wear warning soundmeans your vehicle needs service. Ifyou ignore this audible warning, youwill eventually lose braking perform‐ance, which could lead to a seriousaccident.
Foot parking brake
Applying the parking brake
0:',
To engage the parking brake, first apply
the foot brake and then depress the
parking brake pedal down as far as possible.
CAUTION
•Driving with the parking brake ap‐plied will cause excessive brakepad (or lining) and brake rotorwear.
(Continued)
(Continued)
•Do not operate the parking brakewhile the vehicle is moving exceptin an emergency situation. It coulddamage the vehicle system andmake endanger driving safety.
Releasing the parking brake
To release the parking brake, depress
the parking brake pedal a second time while applying the foot brake. The ped‐
al will automatically extend to the fully
released position.

Anti-lock brake system (ABS)
WARNING
ABS (or ESC) will not prevent acci‐dents due to improper or dangerousdriving maneuvers. Even though ve‐hicle control is improved duringemergency braking, always maintaina safe distance between you and ob‐jects ahead. Vehicle speeds shouldalways be reduced during extremeroad conditions.The braking distance for vehicleequipped with an anti-lock brakingsystem (or Electronic Stability Con‐trol) may be longer than for thosewithout it in the following road con‐ditions.During these conditions the vehicleshould be driven at reduced speeds:•Rough, gravel or snow-coveredroads.
•With tire chains installed.
•On roads where the road surface ispitted or has different surfaceheight.
(Continued)
(Continued)
The safety features of an ABS (orESC) equipped vehicle should not betested by high speed driving or cor‐nering. This could endanger thesafety of yourself or others.
The ABS continuously senses the speed
of the wheels. If the wheels are going to lock, the ABS system repeatedly
modulates the hydraulic brake pressure
to the wheels.
When you apply your brakes under conditions which may lock the wheels,
you may hear a L

CAUTION
•If the ABS warning light is on andstays on, you may have a problemwith the ABS. In this case, howev‐er, your regular brakes will worknormally.
(Continued)
(Continued)
•The ABS warning light will stay onfor approximately 3 seconds afterthe engine start/stop buttonswitch is ON. During that time, theABS will go through self-diagnosisand the light will go off if every‐thing is normal. If the light stayson, you may have a problem withyour ABS. We recommend that youcontact an authorized Kia dealer.
CAUTION
•When you drive on a road havingpoor traction, such as an icy road,and operate your brakes continu‐ously, the ABS will be active con‐tinuously and the ABS warninglight may illuminate. Pull your ve‐hicle over to a safe place and stopthe engine.
•Restart the engine. If the ABSwarning light is off, then your ABSsystem is normal. Otherwise, youmay have a problem with the ABS.We recommend that you contactan authorized Kia dealer.
NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens be‐
cause of the low battery voltage. It
does not mean your ABS is malfunc‐
tioning.
•Do not pump your brakes!
•Have the battery recharged before
driving the vehicle.

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

• EPS (Electronic Power Steering) indi‐cator light remains on the instrument
cluster
VSM operation off
If you press the ESC OFF button to turn
off the ESC, the VSM will also cancel and the ESC OFF indicator light (
) illu‐
minates.
To turn on the VSM, press the button
again. The ESC OFF indicator light goes out.
Malfunction indicator
The VSM can be deactivated even if you
don’t cancel the VSM operation by pressing the ESC OFF button. It indi‐
cates that a malfunction has been de‐
tected somewhere in the EPS (Elec‐ tronic Power Steering) system or VSM
system. If the ESC indicator light (
) or
EPS warning light remains on, we rec‐
ommend that the system be checked by an authorized Kia dealer.
NOTICE
•The VSM is designed to function
above approximately 22 km/h
(13 mph) on curves.
(Continued)
(Continued)
•The VSM is designed to function
above approximately 10 km/h
(6 mph) when a vehicle is braking
on a split-mu road. The split-mu
road is made of surfaces which
have different friction forces.
WARNING
•The Vehicle Stability Managementsystem is not a substitute for safedriving practices but a supplemen‐tary function only. It is the respon‐sibility of the driver to alwayscheck the speed and the distanceto the vehicle ahead. Always holdthe steering wheel firmly whiledriving.
•Your vehicle is designed to activateaccording to the driver’s intention,even with the VSM installed. Al‐ways follow all the normal precau‐tions for driving at safe speed forthe conditions – including driving ininclement weather and on a slip‐pery road.
(Continued)
(Continued)
•Driving with varying tire or wheelsizes may cause the VSM systemto malfunction. When replacingtires, make sure they are thesame size as your original tires.
Hill-start assist control (HAC) (if
equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go af‐ ter stopping. The Hill-start Assist Con‐
trol (HAC) prevents the vehicle from
slipping back by operating the brakes automatically for about 1~2 seconds.
The brakes are released when the ac‐
celerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about1~2 seconds, so when the vehicle isstarting off always depress the ac‐celerator pedal.
Driving your vehicle
7-34

NOTICE
•The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
•The HAC activates even though
the ESC is off but it does not acti‐
vate when the ESC has malfunc‐
tioned.
Emergency Stop Signal (ESS) (if
equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking the
stop light when the vehicle is braked
rapidly and severely. The system is activated when: • The vehicle suddenly stops (vehicle speed is over 55 km/h and the vehicle
deceleration at greater than 7 m/s 2
).
• The ABS is activating.
When the vehicle speed is under
40 km/h and the ABS deactivates or the sudden stop situation is over, the
stop light blinking will stop. Instead, the
hazard warning flasher will turn on au‐ tomatically. The hazard warning flasher will turn off
when vehicle speed is over 10 km/h af‐
ter the vehicle has stopped. Also, it will
turn off when the vehicle is driven at low speed for some time. You can turn
it off manually by pushing the hazard
warning flasher switch.
CAUTION
The Emergency Stop Signal (ESS)system will not work if the hazardwarning flasher is already on.
Good braking practices
WARNING
•Whenever you leave or park yourvehicle, always set the parkingbrake as far as possible and fullyengage the vehicle's transaxle intothe P (Park) position. If the parkingbrake is not fully engaged, the ve‐hicle may move inadvertently andinjure yourself and others.
(Continued)
(Continued)
•All vehicles should always have theparking brake fully engaged whenparking to avoid inadvertentmovement of the vehicle whichcan injure occupants or pedes‐trians.
• Check to be sure the parking brake is not engaged and that the parking
brake indicator light is out before driving away.
• Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your vehi‐
cle will not stop as quickly if the brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the ve‐ hicle under control at all times. If the
braking action does not return to
normal, stop as soon as it is safe to
do so and we recommend that you call an authorized Kia dealer.
