Hyundai Sonata: Shift lock system
For your safety, the automatic transaxle has a shift lock system which prevents shifting the transaxle from P (Park) or N (Neutral) into R (Reverse) unless the brake pedal is depressed.
To shift the transaxle from P (Park) or N (Neutral) 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 near the shift lever may be heard. This is a normal condition.
WARNING
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 car.

Shift-lock override
If the shift lever cannot be moved from the P (Park) or N (Neutral) position into R (Reverse) position with the brake pedal depressed, continue depressing the brake, then do the following:
1. Carefully remove the cap (1) covering the shift-lock access hole.
2. Insert a key (or screwdriver) into the access hole and press down on the key
(or screwdriver).
3. Move the shift lever.
4. Have your vehicle inspected by an authorized HYUNDAI dealer immediately.
