Tesla recommends the following maintenance items and intervals, as applicable to your vehicle, to ensure continued reliability and efficiency of your Model S.

For additional information on vehicle alerts, see Troubleshooting Alerts.

• Brake fluid health check every 4 years (replace if necessary)*.
• A/C desiccant bag replacement every 3 years.
• Cabin air filter replacement every year.
• HEPA filters replacement every year.
• Clean and lubricate brake calipers every year or 12,500 miles (20,000 km) if in an area where roads are salted during winter.
• Rotate tires every 10,000 km or if tread depth difference is 1.5 mm or greater, whichever comes first.

*Heavy brake usage due to towing, mountain descents, or performance driving -- especially for vehicles in hot and humid environments -- may necessitate more frequent brake fluid checks and replacements.

Scheduling a service visit through the mobile app is easy. After touching Service, select the type of service needed and follow the directions in the mobile app. Provide as much detail as possible to better help the Service team identify the cause of concern, such as:

• Photos, sound recordings, or videos.
• Date(s), time(s), and time zone when the issue occurred.
• Country of use and location.
• Approximate speed the vehicle was traveling (if applicable).
• Environmental conditions (rain, snow, cold, etc.).
• Road name and type of road (if applicable).
• Quality of lane markings (if applicable).
• Applicable vehicle settings.
• Identifiable symptoms.

• Check the Battery’s charge level, displayed on the instrument panel or mobile app.
• Check the condition and pressure of each tire (see Tire Care and Maintenance).
• Check that all exterior lights, horn, turn signals, and wipers and washers are working.
• Check for any unexpected indicator lights or vehicle alerts on the touchscreen or instrument panel.
• Check the operation of the brakes, including the parking brake.
  Note

  Because Model S uses regenerative braking (see Regenerative Braking), the brake pads are typically used less frequently than those in traditional braking systems. To avoid the accumulation of rust and corrosion, Tesla recommends frequently pressing the brake pedal to apply the mechanical brakes, which dries the brake pads and rotors.
• Check the operation of the seat belts (see Seat Belts).
• Look for abnormal fluid deposits underneath Model S that might indicate a leak. It is normal for a small pool of water to form (caused by the air conditioning system’s dehumidifying process).
• Look around the exterior of Model S and immediately remove any corrosive substances (such as bird droppings, tree resin, tar spots, dead insects, industrial fallout, etc.) to prevent damage to the exterior (see Cleaning).

• During wet weather, clean Autopilot cameras weekly (see Cleaning a Camera). Otherwise, clean them monthly during dry weather.

• Check windshield washer fluid level and top up if necessary (see Topping Up Windshield Washer Fluid).
• Check that the air conditioning system is operating correctly (see Operating Climate Controls).

Perform the following checks as needed:

Over time, when driving in dusty or polluted conditions, your vehicle's radiator may become clogged. This can affect air flow and heating/AC performance. To clean, do it yourself by navigating to the Service Manual. Alternatively, use the mobile app to schedule a service appointment.

Battery coolant and brake fluid levels should only be checked by Tesla or a professional automotive repair shop. Specific service information is available in the Service Manual.

• Battery coolant: Your Battery coolant does not need to be replaced for the life of your vehicle under most circumstances.
  Note

  Any damage caused by opening the Battery coolant reservoir is excluded from the warranty.
• Brake fluid: Do not top up your brake fluid.

Updating software is important to ensure proper operation and longevity of your vehicle's components. You must install a software update at the earliest opportunity. See Software Updates.

Tesla may update or reinstall your vehicle's software as part of the normal diagnostic, repair, and maintenance process within Service.

Your Model S has been designed and built with safety as a priority. However, be aware of these precautions to protect yourself from the risk of injury inherent in all high-voltage systems:

• Read and follow all instructions provided on the labels that are attached to Model S. These labels are there for your safety.
• The high voltage system has no user-serviceable parts. Do not disassemble, remove or replace high voltage components, cables or connectors. High voltage cables are colored orange for easy identification.
• If a collision occurs, do not touch any high voltage wiring, connectors, or components connected to the wiring.
• In the unlikely event that a fire occurs, immediately contact your local fire emergency responders.
