To prevent damage to the paint, immediately remove corrosive substances (bird droppings, tree resin, dead insects, tar spots, road salt, industrial fallout, etc.). Do not wait until Model S is due for a complete wash. If necessary, use denatured alcohol to remove tar spots and stubborn grease stains, then immediately wash the area with water and a mild, non-detergent soap to remove the alcohol.
Keep the exterior cameras free of dirt, condensation, or obstructions. These substances can cause unclear pictures or Autopilot and safety features to stop working (see Cleaning a Camera).
Follow these steps when washing the exterior of Model S:
1. Rinse Thoroughly
Before washing, flush grime and grit from the vehicle using a hose. Flush away accumulations of mud in areas where debris easily collects (such as wheel wells and panel seams). If salt has been used on the highways (such as during winter months), thoroughly rinse all traces of road salt from the underside of the vehicle, wheel wells, and brakes.
2. Hand Wash
Hand wash Model S using a clean soft cloth and cold or lukewarm water containing a mild, high-quality car shampoo.
CAUTION: Some cleaners and car shampoos contain chemicals that can cause damage or discoloration, especially to plastic trim pieces, lamps, or camera lenses. For example, some car cleaning formulas contain hydroxide or other highly alkaline or caustic ingredients that can damage exterior components. Damage or discoloration resulting from cleaning products is not covered by the warranty.
3. Rinse with Clean Water
After washing, rinse with clean water to prevent soap from drying on the surfaces.
4. Dry Thoroughly and Clean Exterior Glass
After washing and rinsing, dry thoroughly with a chamois. If necessary, dry the brakes by going on a short drive and applying the brakes multiple times.
Clean windows and mirrors using an automotive glass cleaner. Do not scrape, or use any abrasive cleaning fluid on glass or mirrored surfaces.
Car Wash Mode
When taking Model S to a car wash, Car Wash Mode closes all windows, locks the charge port, and disables windshield wipers, Sentry Mode, walk-away door locking, and parking sensor chimes. To enable, touch Controls > Service > Car Wash Mode. Your vehicle must be stationary and not actively charging.
If using an automatic car wash, Enable Free Roll keeps your vehicle in Neutral and activates free roll for the duration of the wash, while preventing Model S from applying the Parking brake if you leave the driver's seat. To enable, press on the brake pedal and touch Enable Free Roll; or shift into Neutral.
Car Wash Mode disables if the vehicle's speed exceeds 9 mph (15 km/h) or by touching Exit on the touchscreen.
CAUTION: Failure to put Model S in Car Wash Mode may result in damage (for example, to the charge port or windshield wipers). Damage caused by car washes is not covered by the warranty.
Cleaning a Camera
To ensure a clear picture, the camera lens must be clean and free of obstructions. Remove any build-up of dirt or debris by spraying water onto the camera lens with a spray bottle or pressure washer.
CAUTION: Do not attempt to remove dirt or debris by wiping an exposed lens with your hands or a cloth. This debris can damage the surface of the lens when rubbed against it during wiping.
CAUTION: Do not use chemical-based or abrasive cleaners. Doing so can damage the surface of the lens.
Cautions for Exterior Cleaning
CAUTION: Do not wash in direct sunlight.
CAUTION: Do not use windshield treatment fluids. Doing so can interfere with wiper friction and cause a chattering sound.
CAUTION: Do not use hot water, detergents, or highly alkaline or caustic cleaning products, especially those containing hydroxide.
CAUTION: If using a pressure washer, maintain a distance of at least 12" (30 cm) between the nozzle and the surface of Model S. Avoid aiming the water jet directly at parking sensors (if equipped). Keep the nozzle moving and do not concentrate the water jet on any one area.
CAUTION: Do not aim water hoses directly at windows, door, or hood seals or at electronic modules or exposed cabling.
CAUTION: To avoid corrosive damage that may not be covered by the warranty, rinse away any road salt from the underside of the vehicle, wheel wells, and brakes. After cleaning the vehicle, dry the brakes by going on a short drive and applying the brakes multiple times.
CAUTION: Avoid using tight-napped or rough cloths, such as washing mitts. A high-quality microfiber cleaning cloth is recommended.
CAUTION: If washing in an automatic car wash, use touchless car washes only. These car washes have no parts (brushes, etc.) that touch the surfaces of Model S. Some touchless car washes use caustic solutions that, over time, can cause discoloration of decorative exterior trim. Avoid exposure to soaps and chemicals above pH 13. If unsure, check the product label or ask the staff at the car wash. Damage caused by improper washing is not covered by the warranty.
CAUTION: If washing in an automatic car wash, make sure the vehicle is locked. In addition, avoid using controls on the touchscreen that can result in accidentally opening doors or trunks while the vehicle is being washed. Any damage caused is not covered by the warranty.
CAUTION: Ensure the wipers are off before washing Model S to avoid the risk of damaging the wipers.
CAUTION: Do not use chemical based wheel cleaners or pre-wash products. These can damage the finish on the wheels.
WARNING: Never spray liquid at a high velocity (for example, if using a pressure washer) towards the charge port while Model S is charging. Failure to follow these instructions can result in serious injury or damage to the vehicle, charging equipment, or property.
