* Fore/Aft (Forward/Backward): This is usually a lever located under the front of the seat cushion, near the seat's leading edge. You'll likely need to pull up or push down on this lever to release the locking mechanism, then slide the seat forward or backward to your desired position.
* Seatback Recline: This is typically a knob or lever located on the side of the seatback, usually on the outer edge near the shoulder. Turn the knob or pull/push the lever to adjust the angle of the backrest.
* Height Adjustment (If Equipped): Some 1990 Jettas might have a height adjustment feature. This would usually involve a lever or crank somewhere under the seat cushion, possibly near the fore/aft adjustment lever.
To adjust your seat:
1. Locate the levers/knobs: Carefully inspect the front and sides of your seat cushion and backrest to find the adjustment mechanisms described above.
2. Release the locking mechanism: For the fore/aft adjustment, pull up or push down on the lever to unlock it. For the recline, operate the knob or lever.
3. Adjust the seat: Slide the seat forward or backward, or adjust the recline angle to your preferred position.
4. Lock the seat in place: Once in the desired position, release the fore/aft lever (it should usually automatically lock) or ensure the recline control is secure.
If you're having trouble locating the controls, consult your owner's manual (if you have one) or search online for images of a 1990 VW Jetta's interior—this can help you visually identify the adjustment levers. Remember, these are general instructions and your specific seat might have minor variations.
