Rear tire tread depth low - Schedule service
Inspect tires for rotation/replacement
What this alert means:
NOTE: This alert does NOT indicate that there is a flat tire.
Your vehicle has detected that the rear tires have experienced more wear over time than the front tires, exceeding the recommended
difference.
What to do:
It is recommended that the tread depth on all tires be inspected. As your tires wear during normal driving, the rear tires generally wear more quickly than the front tires.
Tire rotation is important to balance tire wear evenly across all tires. 3When staggered tires (different front and rear
tire sizes) are installed, regularly rotating the front and rear tires between the left and right sides of your vehicle will
still make your tires wear more evenly and extend their life.
Failure to rotate tires as recommended poses a risk of hydroplaning and losing control of the vehicle on wet roads.
Failure to rotate tires also decreases the life of your tires, requiring premature replacement.
It is recommended that you schedule service via your Tesla Mobile App or with an independent service provider to
have your tires rotated when:

Continue to your destination. Your vehicle is OK to drive.
If this alert persists throughout subsequent drives, schedule service at your earliest convenience. Your vehicle is OK
to drive in the meantime.
For more information, see Vehicle Hold on page 72.
EPBL_a195 / EPBR_a195
Vehicle automatically parked to prevent rollaway
Fasten seatbelt and close door to stay in gear
What this alert means:
Your vehicle has automatically shifted into Park (P) because it determined the driver was leaving or no longer
present. This is expected vehicle behavior under various circumstances.
Your vehicle will automatically shift into Park if all of these conditions are true:

Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake
temperatures after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your
brake pads or rotors have worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla
service at your convenience for a brake inspection.
For more information, see Hydraulic Fade Compensation on page 66.
PCS_a016
Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
What this alert means:
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This may be due to power supply disturbances caused by the external charging equipment or by the electrical
power grid. In some cases, this condition may be the result of using nearby electric devices that draw a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
What to do:
If this alert is accompanied by another alert that specifies the condition affecting AC charging, start by investigating
that alert.
Further troubleshooting tips based on equipment type:

PCS_a052
External charging equipment not providing power
Check power source or try different equipment
What this alert means:
Charging cannot begin due to a condition that prevents your vehicle from charging with AC power. DC fast charging / Supercharging should still function as expected.
Your vehicle has requested AC power from the external charging equipment, but the onboard charger does not detect any supply voltage coming from the equipment.
This can sometimes be caused by a hardware issue specific to the external charging equipment, which prevents the
charging equipment from switching power to the vehicle on or
off when requested. It could also occur due to
another condition
affecting the external charging equipment, the power source it is connected to, or your vehicle
itself.
What to do:
This alert is usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
Try charging with multiple, different types of charging equipment.
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 usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
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

What to do:
As this alert can be present due to various conditions, it is recommended that you schedule service at your earliest
convenience.

VCFRONT_a216
Vehicle may not restart - Service is required
Electrical system issue detected
What this alert means:
An abnormally large and sustained power draw while driving or Supercharging / DC Fast Charging has made your
vehicle

It is recommended that you schedule service at your earliest opportunity. Without service, your vehicle will remain
unable to restart, and the electrical system will remain unable to support all features and functions.
Some or all of the powered doors and windows in your vehicle may lose electrical power. If this occurs, you can still
use the manual door releases to exit the vehicle if necessary. For more information, see Opening Doors from the
Interior on page 14.
VCFRONT_a220
Electrical system is unable to support all features
Schedule service
What this alert means:
The low voltage battery is not available and cannot provide electrical support for vehicle features.
It is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the
current drive.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.

Electrical system backup power is unavailable
Vehicle will consume more energy while idle
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the
voltage required to support all vehicle features.
The primary source of electrical power, the high voltage battery system, will continue to support vehicle functions,
even when your vehicle is idle. For more information on the high voltage battery, see
About the High Voltage Battery
on page 167.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down
unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain
adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the
electrical system can be restored.
