The S90 is an automatic transmission model. Below are the operation methods for the Volvo S90: 1. Press the brake pedal to start the vehicle; 2. Shift the gear into D gear; 3. Press the electronic handbrake; 4. Release the brake and the vehicle can move. The following is extended information about the 2021 Volvo S90: 1. The Volvo S90 is a mid-to-large-sized car, with body dimensions of length 5090mm, width 1879mm, height 1450mm, a wheelbase of 3061mm, and a fuel tank capacity of 55L; 2. The 2021 Volvo S90 has a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L turbocharged engine, with a maximum horsepower of 250ps, a maximum power of 184kw, a maximum torque of 350nm, and is matched with an 8-speed automatic transmission.

To start the S90, simply press the start button while holding the brake pedal, and the electronic parking brake will automatically release. The steering wheel buttons are particularly intuitive—the left side controls driving assistance features, making highway driving effortless with adaptive cruise control and Pilot Assist; just press a button to set the speed and follow the car ahead. The right side has multimedia shortcuts for easily skipping tracks or adjusting the volume. My favorite is the vertical touchscreen on the center console, which operates like a tablet for controlling the AC, navigation, and CarPlay, and even supports voice commands. The 360-degree camera is super clear when reversing, and the parking sensors are highly responsive. Seat ventilation and heating are adjusted via the door panel, while the massage function is a lifesaver on long drives. The rain-sensing wipers and automatic headlights work seamlessly in wet weather. Remember to enable the blind-spot monitoring for safer lane changes. When the maintenance reminder light comes on, you can directly schedule service at the dealership via the center console.

When driving the S90, pay attention to the crystal gear knob—just a gentle twist to shift gears, with the P button located on top. This car emphasizes eco-friendliness; its air purification system can monitor PM2.5 levels in real-time via the AC interface. The mobile app's remote start feature is incredibly practical, allowing you to cool the car by turning on the AC in advance during summer. The vehicle settings in the central screen hide little surprises, like adjusting ambient lighting colors and setting a delay for homecoming lighting. The seat memory buttons are on the door panel—once set, even the mirrors adjust automatically. The automatic parking function is activated by pressing the P button near the gear knob, though I find manual parking saves more time. Welcome lights illuminate when the key approaches, and the hidden door handles pop out automatically upon unlocking.

New to driving the S90? Don't panic, let me teach you a few key points. Adjust the seat and steering wheel before starting, the leg support is crucial. When shifting gears, press the brake and rotate the gear knob to D for vibration feedback. Common buttons are at the bottom of the central screen, with the hazard lights and defogger buttons being the most frequently used. For air conditioning, just tell the voice assistant the temperature—it's much faster than manual adjustment. The silver roller on the left side of the steering wheel adjusts cruise speed; the pilot assist only activates when the green light is on. The electronic child lock is a switch on the inner side of the rear door—remember to lock it if kids are sitting in the back. The rearview mirror heating and rear window defogger share the same button. When turning off the engine, simply open the door to automatically shift to P, and the car will beep if the key is left inside.

The driving mode selector knob is located next to the gear lever. For daily use, the Comfort mode is sufficient, while the Eco mode makes the throttle response less sensitive. The steering wheel weight can be adjusted in the settings, and it's recommended to set it lighter for female drivers. The safety system is quite intelligent; the lane-keeping feature vibrates the steering wheel as a reminder when slightly crossing the line. My favorite is the City Safety system, which automatically brakes if a pedestrian suddenly steps out. On the highway, the Pilot Assist feature allows you to drive with just a light touch on the steering wheel. The Bowers & Wilkins audio system sounds best with lossless music played via USB, as audio quality is noticeably inferior. The front wireless charging pad is discreetly located at the bottom of the center console storage compartment. The rear center armrest, when lowered, reveals controls for air conditioning and seat heating. The sunshade button is in the overhead control panel, and remember to turn off the ambient lighting at night to save power.

The S90 is exceptionally quiet to drive, and the secret is to turn off the engine start-stop in the settings. When starting, don't press the accelerator too hard; a light press is enough for speed. The main interface of the central control screen can be customized—I set the navigation map to stay permanently. The infotainment system supports both Android and Apple screen mirroring, but you'll need the original data cable. The rearview mirror's anti-glare feature is automatic, so no manual adjustment is needed. For one-touch window operation, press the button all the way down; releasing it midway will stop the window. There are four display modes for the instrument cluster, with the classic mode being the clearest. The rear USB ports are inside the center armrest—remember to open the cover when charging. The door storage compartments have cup holder limiters to keep thermoses from wobbling. Holding down the lock button on the key fob closes all windows, which is super convenient for cooling down in summer. The cabin air filter should be replaced every quarter to avoid odors.
