2020 Kia Optima Owners Manual - Automatic transmission



Automatic transmission

Automatic transmission operation

The automatic transmission has 6 forward speeds and one reverse speed. The individual speeds are selected automatically, depending on the position of the shift lever.

✽ NOTICE

The first few shifts on a new vehicle, if the battery has been disconnected, may be somewhat abrupt. This is a normal condition, and the shifting sequence will adjust after shifts are cycled a few times by the TCM (Transmission Control Module) or PCM (Powertrain Control Module).

For smooth operation, depress the brake pedal and the lock release button when shifting from N (Neutral) to a forward or reverse gear.

WARNING - Leaving Vehicle

Before leaving the driver’s seat, always make sure the shift lever is in the P (Park) position; then set the parking brake fully and shut the engine off. Do not use the P position in place of the parking brake. Always make sure the shift lever is locked in the P position and set the parking brake fully. Unexpected and sudden vehicle movement can occur if these precautions are not followed.

CAUTION - Transmission

To avoid damage to your transmission, do not accelerate the engine in R (Reverse) or any forward gear position with the brakes on. The transmission may be damaged if you shift into P (Park) while the vehicle is in motion.

When stopped on an incline, do not hold the vehicle with the engine power. Use the service brake or the parking brake.

Transmission ranges

The indicator in the instrument cluster displays the shift lever position when the ignition switch is in the ON position.

P (Park)

Always come to a complete stop before shifting into P (Park). This position locks the transmission and prevents the drive wheels from rotating.

Shifting into P (Park) while the vehicle is in motion will cause the drive wheels to lock which will cause you to lose control of the vehicle.

R (Reverse)

Use this position to drive the vehicle backward.

CAUTION - Shifting

Always come to a complete stop before shifting into or out of R (Reverse); you may damage the transmission if you shift into R (Reverse) while the vehicle is in motion, except when “Rocking the vehicle” explained in this chapter.

N (Neutral)

The wheels and transmission are not engaged. The vehicle will roll freely even on the slightest incline unless the parking brake or service brakes are applied.

Parking in N (Neutral) gear

Follow the steps below when parking and you want the vehicle to move when pushed.

1. After stopping your vehicle, depress the brake pedal and move the transmission shift lever to [P] with the ignition button in [ON] or while the engine is running.

2. If the parking brake is applied, release the parking brake.

3. While depressing the brake pedal, turn the ignition button [OFF].
- For smart key equipped vehicles, the ignition switch can be moved to [OFF] only when the shift lever is in [P].

4. Change the gear shift lever to [N] (Neutral) while depressing the brake pedal and inserting a tool (e.g. flathead screw-driver) into the [SHIFT LOCK RELEASE] access hole at the same time. Then, the vehicle will move when external force is applied.

WARNING

  • With the exception of parking in neutral gear so that you can push the vehicle, always park the vehicle in [P] (Park) for safety and apply the parking brake.
  • Before parking in [N] (Neutral) gear, first make sure the parking ground is level and flat. Do not park in [N] gear on any slopes or gradients. If parked and left in [N], the vehicle may move and cause serious damage or injury.

CAUTION - Starter

If the engine stalls while the vehicle is in motion, do not attempt to move the shift lever to the P (Park) position. If the traffic and road conditions permit, you may put the shift lever in the N (Neutral) position while the vehicle is still moving and press the engine start/stop button in an attempt to restart the engine.

D (Drive)

This is the normal forward driving position. The transmission will automatically shift through a 6-gear sequence, providing the best fuel economy and power.

For extra power when passing another vehicle or climbing grades, depress the accelerator fully, at which time the transmission will automatically downshift to the next lower gear.

Manual mode

Whether the vehicle is stationary or in motion, manual mode is selected by pushing the shift lever left from the D (Drive) position into the manual gate.

To return to D (Drive) range operation, push the shift lever right back into the main gate. In manual mode, moving the shift lever backwards and forwards will allow you to make gearshifts rapidly. In contrast to a manual transmission, the manual mode allows gearshifts with the accelerator pedal depressed.

Up (+) : Push the lever forward once to shift up one gear.

Down (-) : Pull the lever backwards once to shift down one gear.

  • 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 forward gears can be selected. To reverse or park the vehicle, move the shift lever to the main gate and then select R (Reverse) or P (Park) position as required.
  • In manual mode, downshifts are made automatically when the vehicle 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 automatically.
  • To maintain the required levels of vehicle performance and safety, the system may not execute certain gearshifts when the shift lever is operated.
  • When driving on a slippery road, push the shift lever forward into the +(up) position. This causes the transmission to shift into the 2nd gear which is better for smooth 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 transmission has a shift lock system which prevents shifting the transmission from P (Park) into R (Reverse) unless the brake pedal is depressed.

To shift the transmission from P (Park) into R (Reverse):

1. Depress and hold the brake pedal.

2. Start the engine or turn the ignition switch to the ON position.

3. Move the shift lever.

If the brake pedal is repeatedly depressed and released with the shift lever in the P (Park) position, a chattering noise and vibration near the shift lever may be hear, and is a normal condition. Repeated operation can cause overheat condition, and stop operating, until sufficient cooled down.

WARNING - Shifting from park

Always fully depress the brake pedal before and while shifting out of the P (Park) position into another position to avoid inadvertent motion of the vehicle which could injure persons 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 depressed, continue depressing the brake, then do the following:

1. Place the ignition switch in the LOCK/OFF position.

2. Apply the parking brake.

3. Carefully remove the cap (1) covering the shift-lock release access hole.

4. Insert a tool (e.g. flathead screwdriver) into the access hole and press down on the tool.

5. Move the shift lever.

6. Remove the tool from the shiftlock override access hole then install the cap.

7. Have the system inspected by an authorized Kia dealer.

Ignition key interlock system

The ignition key cannot be removed unless the shift lever is in the P (Park) position. Even if the ignition switch is in the LOCK position, the key cannot be removed.

If your vehicle is equipped with engine start/stop button, the button will not change to the OFF position unless the shift lever is in the P (Park) position.

Good driving practices

  • Never move the gear shift lever from P (Park) to any other position with the accelerator pedal depressed.
  • Never move the gear shift lever into P (Park) when the vehicle is in motion.
  • Slow down before shifting to a lower gear. Otherwise, the lower gear may not be engaged.
  • Always use the parking brake. Do not depend on placing the transmission in P (Park) to keep the vehicle from moving.
  • Optimum vehicle performance and economy is obtained by smoothly depressing and releasing the accelerator pedal.

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 service brakes.

When accelerating from a stop on a steep hill, the vehicle may have a tendency to roll backwards. Shifting the shift lever into 2 (Second Gear) will help prevent the vehicle from rolling backwards.
