Kia Optima: Automatic transmission operation / Shift lock system

Kia Optima DL3 2019-2020 Owner's Manual / Driving your vehicle / Automatic transmission / Automatic transmission operation / 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.
