The Volvo S90 stands out in the luxury sedan segment not only for its Scandinavian design and safety innovations but also for its sophisticated comfort features, including fully adjustable power seats and customizable memory functions. These systems are designed to provide an individualized driving experience tailored to each driver’s unique preferences, enhancing both comfort and convenience during every journey. Mastering the adjustment and calibration of these features can significantly improve your driving posture, reduce fatigue on long trips, and ensure that your vehicle consistently adapts to your needs with minimal effort.

Understanding the Power Seat Controls in the Volvo S90

The power seats in the Volvo S90 offer a wide range of adjustments beyond the traditional forward and backward movement. To fully benefit from these features, it’s important to familiarize yourself with all the available controls and how they influence your seating position.

Location of Seat Adjustment Controls

The power seat controls are conveniently located on the outer side of the driver’s and front passenger’s seat bases. These controls include several switches and buttons designed to adjust various aspects of the seat:

  • Seat Position Switch: Moves the entire seat forward or backward and adjusts the height up or down.
  • Seat Cushion Tilt Control: Allows you to raise or lower the front edge of the seat cushion to provide better thigh support.
  • Backrest Angle Control: Adjusts the recline angle of the seatback for optimal comfort.
  • Lumbar Support Adjustment: Modifies the firmness and positioning of the lumbar area in the seatback to support the lower spine.

Step-by-Step Guide to Adjusting Your Seat

  1. Set Your Seat Height: Use the height control to raise or lower the seat until you have a clear view over the dashboard and can comfortably see the road ahead without straining your neck.
  2. Adjust Seat Distance: Slide the seat forward or backward so that your feet rest naturally on the pedals with a slight bend in your knees. This position helps maintain proper circulation and reduces leg fatigue.
  3. Modify Seat Cushion Tilt: Tilt the front edge of the cushion upwards slightly to support your thighs. This adjustment is crucial for maintaining a comfortable and ergonomic seating posture.
  4. Set Backrest Angle: Recline the seatback to a position where your back is fully supported, and you can comfortably reach the steering wheel without overstretching.
  5. Adjust Lumbar Support: Use the lumbar control to increase or decrease support in the lower back region. Proper lumbar support reduces back strain, especially on long drives.

After making these adjustments, double-check that you can easily reach all controls, pedals, and the steering wheel without discomfort. Your shoulders should remain relaxed, and your arms should have a slight bend when holding the steering wheel. Proper posture minimizes fatigue, enhances control, and contributes to overall driving safety.

Calibrating and Using the Memory Seat Functions

One of the standout features of the Volvo S90 is the memory system, which allows multiple drivers to save their preferred seat, mirror, and steering wheel positions. This system not only saves time but also ensures that each driver can instantly restore their ergonomic settings, promoting comfort and reducing adjustment errors.

What Does the Memory Function Store?

The memory function in the S90 typically saves settings for:

  • Driver’s seat position, including height, tilt, backrest angle, and lumbar support
  • Side mirror angles
  • Steering wheel position (if equipped with power adjustment)

Some models may also allow additional settings, such as climate control preferences or head-up display configurations, to be saved within the driver profiles.

How to Program the Memory Settings

Follow these detailed steps to ensure your settings are correctly saved and easily recalled:

  1. Adjust Your Seating Position: Use the power seat controls to find a comfortable and ergonomic driving position, ensuring optimal posture.
  2. Set Side Mirrors: Adjust the exterior side mirrors for maximum visibility with minimal blind spots.
  3. Position the Steering Wheel: If your S90 is equipped with an electrically adjustable steering column, move it to your preferred height and distance.
  4. Activate the Memory Function: On the driver’s door panel, locate the “SET” button near the memory position buttons (usually labeled “1” and “2”). Press and hold the “SET” button until you hear an audible beep, indicating the system is ready to save the settings.
  5. Save Your Profile: Within five seconds of pressing “SET,” press and hold one of the numbered memory buttons (e.g., “1”) until you hear a confirmation beep. This saves your current settings to that memory slot.
  6. Repeat for Additional Drivers: Another driver can repeat the process to save their preferred settings to the second memory button (e.g., “2”).

Once programmed, pressing the respective memory button will automatically adjust the seat, mirrors, and steering wheel to the saved positions, even if you or another driver had previously altered them.

Recalling Saved Settings

To recall a saved profile:

  • Simply press the corresponding memory button once. The seat, mirrors, and steering wheel will move to the stored positions automatically.
  • If the vehicle is equipped with key fob recognition linked to driver profiles, the S90 may automatically recall your saved settings when you unlock the car with your key.

Troubleshooting Memory Functions and Power Seat Issues

While the power seats and memory functions are designed for reliability, occasional issues can arise. Here are some common problems and solutions to keep your system functioning smoothly:

Power Seat Not Responding

  • Check the Ignition: Power seat adjustments typically only work when the ignition is on or in accessory mode. Verify that the vehicle is powered appropriately.
  • Inspect the Fuses: A blown fuse can cause the power seat to stop working. Refer to the owner's manual for the fuse box location and check the fuse related to seat controls.
  • Reset the System: Some electrical glitches can be resolved by turning the car off, waiting a few minutes, and restarting.

Memory Buttons Not Saving or Recalling Positions

  • Ensure Correct Procedure: Make sure you are pressing and holding the “SET” button before pressing the memory position button during programming.
  • Battery Voltage: Low vehicle battery voltage can interfere with electronic memory functions. Have your battery tested if the problem persists.
  • Software Updates: Occasionally, software updates from Volvo dealerships can resolve memory function bugs.

Advanced Features and Customization Options

The Volvo S90’s power seat system often includes additional features that further enhance comfort and customization:

Massage Function

Available on higher trim levels or as an optional feature, the massage function provides targeted lumbar and back massages with adjustable intensity and patterns. This feature can be activated and customized via the center console touchscreen or the Volvo On Call app, adding an extra layer of relaxation during long drives.

Ventilated and Heated Seats

Depending on your model and trim, the seats may include heating and ventilation. These climate controls are typically integrated with the seat memory system, allowing each driver to save their preferred temperature settings along with seat position.

Integration with Driver Profiles and Key Fobs

Many modern Volvo S90s allow you to create multiple driver profiles linked to individual key fobs. When you unlock the car with your key, the vehicle automatically adjusts the seat, mirrors, steering wheel, and even climate settings based on the associated profile. This seamless integration eliminates the need to manually select memory positions every time you drive.

Maintaining Your Power Seats for Longevity

To ensure your power seats and memory functions continue working reliably over time, consider these maintenance tips:

  • Keep the Seat Rails Clean: Dirt and debris can accumulate in the seat tracks, impeding smooth movement. Regularly vacuum and clean these areas.
  • Avoid Excessive Force: Use only the electrical controls to move the seat; manually forcing the seat can damage motors and mechanisms.
  • Protect Electronic Components: Avoid spilling liquids near the seat controls or memory buttons to prevent electrical shorts.
  • Update Software: Participate in scheduled software updates at authorized Volvo service centers to keep electronic systems optimized.

Conclusion

The power seats and memory functions in the Volvo S90 are prime examples of Volvo’s commitment to combining luxury with user-friendly technology. Taking the time to properly adjust and calibrate these features not only enhances comfort but also promotes safer driving by ensuring optimal posture and reducing distractions caused by frequent seat adjustments. By understanding the full range of adjustments, programming memory settings, and maintaining the system, you can enjoy a personalized and effortless driving experience every time you get behind the wheel of your S90.
