Charging Instructions

Cleaning the Exterior
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 Y 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. Occasionally remove any buildup of dirt by
wiping the components with a soft cloth dampened with warm water. These substances can cause autopilot and safety features to stop working (see
Cleaning Cameras
and Sensors on page 82).
Follow these steps when washing the exterior of Model
Y:
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 Y 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.
Cautions for Exterior CleaningCAUTION: 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 Y. Avoid aiming
the water jet directly on the camera(s) or parking
sensors (if equipped). Also do not clean a sensor
or camera lens with a sharp or abrasive object that
can scratch or damage its surface. 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 Y. 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: Ensure the wipers are off before
washing Model Y 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 Y is charging. Failure
to follow these instructions can result in serious
injury or damage to the vehicle, charging
equipment, or property.
Cleaning

Regularly inspect the exterior paint for damage. Treat minor chips and scratches using a paint touch-up pen (available for purchase from Tesla). Use the touch-up
pen after washing but before polishing or waxing.
Repair rock chips, fractures or scratches. Refer to
https://www.tesla.com/support/body-shop-support for
more information on repair locations and available
services.
CAUTION: Do not use cutting pastes, color
restoration compounds, or polishes containing
harsh abrasives. These can scour the surface and
permanently damage the paint.
CAUTION: Do not use chrome polish or other
abrasive cleaners.
Using a Car Cover
To preserve the cosmetic appearance of the body when
Model Y is not being used, use a genuine Tesla car
cover. Car covers can be purchased from Tesla. See
Parts and Accessories on page 177.
CAUTION: Use only a Tesla-approved car cover
when Model Y is plugged in. Using a non-Tesla car
cover can prevent the Battery from being
adequately cooled during charging.
Floor Mats
To extend the life of your carpet and make them easier
to clean, use genuine Tesla
floor mats (see Parts and
Accessories on page 177). Maintain floor mats by
regularly cleaning them and checking that they are
properly attached. Replace
floor mats if they become
excessively worn.
WARNING: To avoid potential interference with a
foot pedal, ensure that the driver’s floor mat is
securely fastened, and never place an additional
floor mat on top of it. Floor mats should always
rest on top of the vehicle carpeting surface and
not on another floor mat or other covering.

4.
Other hardware component issues
What to do:
An internal issue was detected by the Wall Connector.
1.
Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
2.
If the issue persists, turn OFF the circuit breaker for
the Wall Connector, wait 10 seconds, and turn the circuit breaker ON again. Then try reconnecting the Wall Connector to the vehicle.

You can also try charging your vehicle using a Tesla
Supercharger or Destination Charging location, all of
which can be located through the map on your vehicle

This alert is often accompanied by other alerts that can
help you identify and troubleshoot the issue. Start by
investigating any other displayed alerts that relate to charging issues.
Alternatively, you can check Mobile Connector or Wall Connector status lights to
confirm power to the device,
and also refer to the product owner’s manual for
troubleshooting information based on blink codes. If using other (non-Tesla) external charging equipment, check for a display or other user interface that provides troubleshooting help.
If there is clearly no power to the charging equipment, check the circuit breaker for the wall outlet / Wall Connector to make sure it has not tripped.
