stop start KIA OPTIMA PLUG-IN HYBRID 2017 Repair Manual

NOTICE
•In manual mode, the driver must
execute upshifts in accordance
with road conditions, taking care
to keep the engine speed below
the red zone.
•In manual mode, only the 6 for‐
ward gears can be selected. To re‐
verse or park the vehicle, move
the shift lever to the R (Reverse)
or P (Park) position as required.
•In manual mode, downshifts are
made automatically when the ve‐
hicle slows down. When the vehicle
stops, 1st gear is automatically
selected.
•In manual mode, when the engine
rpm approaches the red zone shift
points are varied to upshift auto‐
matically.
•To maintain the required levels of
vehicle performance and safety,
the system may not execute cer‐
tain gearshifts when the shift lev‐
er is operated.

•When driving on a slippery road,
push the shift lever forward into
the + (up) position. This causes the
transaxle to shift into the 2nd
gear which is better for appropri‐
ate driving on a slippery road.
Push the shift lever to the -
(down) side to shift back to the
1st gear.
Shift lock system
For your safety, the automatic trans‐
axle has a shift lock system which pre‐ vents shifting the transaxle from P
(Park) into R (Reverse) unless the brake
pedal is depressed.
To shift the transaxle from P (Park) in‐ to R (Reverse): 1. Depress and hold the brake pedal.
2. Start the hybrid system or turn the ignition switch to the ON position.
3. Move the shift lever. If the brake pedal is repeatedly de‐
pressed and released with the shift lev‐
er in the P (Park) position, a chattering noise & vibration near the shift lever
may be heard. This is a normal condi‐
tion.
WARNING
Always fully depress the brake pedalbefore and while shifting out of theP (Park) position into another posi‐tion to avoid inadvertent motion ofthe vehicle which could injure per‐sons in or around the vehicle.

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.

•Loss of control often occurs if twoor more wheels drop off the road‐way and the driver oversteers toreenter the roadway.
•In the event your vehicle leavesthe roadway, do not steer sharply.Instead, slow down before pullingback into the travel lanes.
•Never exceed posted speed limits.
WARNING
If your vehicle becomes stuck insnow, mud, sand, etc., then you mayattempt to rock the vehicle free bymoving it forward and backward. Donot attempt this procedure if peopleor objects are anywhere near the ve‐hicle. During the rocking operationthe vehicle may suddenly move for‐ward of backward as it becomes un‐stuck, causing injury or damage tonearby people or objects.
Moving up a steep grade from a
standing start
To move up a steep grade from a
standing start, depress the brake pedal,
shift the shift lever to D (Drive). Select
the appropriate gear depending on load weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the brake pedal.
When accelerating from a stop on asteep hill, the vehicle may have a ten‐dency to roll backwards. Shifting theshift lever into 2 (Second Gear) will helpprevent the vehicle from rolling back‐wards.
