2023 TESLA MODEL S service

Vehicle Hold is currently unavailable due to system constraints. When stopping, use the brake pedal to bring your
vehicle to a complete stop and keep your vehicle stationary.
What to do:
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.
DI_a250
Adaptive ride control disabled
Drive with caution
What this alert means:
The speed of your vehicle is limited to 90 mph (144 km/h) due to an issue with the Adaptive Suspension Damping
system.
The system cannot provide real-time adjustments to the suspension system to optimize both ride and handling, and
as a result your ride may be softer than usual.
What to do:
If this alert persists throughout subsequent drives, schedule service at your earliest convenience. Your vehicle is OK
to drive in the meantime.
This alert is accompanied by a red indicator light on the instrument panel. For more information, see Air Suspension
on page 129.
ESP_a118
Assist for low brake performance activated
To stop, keep brake pedal firmly pressed
What this alert means:
Hydraulic Fade Compensation is active. This brake assist function activates temporarily to make sure you have full
braking capability in conditions where reduced braking performance is detected by your vehicle.
When this assist function activates, you may feel the brake pedal pull away from your foot and notice a strong
increase in brake pressure. You may also hear a pumping sound coming from the brake hydraulic unit at the front of
the vehicle. This will usually last for a few seconds, depending on road surface and vehicle speed. This is completely
normal and does not indicate any issue with your vehicle.
What to do:
Continue to press the brake pedal as you normally would, and do not "pump" (repeatedly press and release) the
pedal as this will interrupt the function.
This alert will clear when your vehicle comes to a stop or you are no longer pressing the brake pedal. It may still be
displayed for up to 5 seconds afterward.
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 67.
Troubleshooting Alerts

If this alert persists when attempting to charge at multiple locations and with different charging equipment, it is
recommended that you schedule service.
For more information on troubleshooting Mobile Connector or Wall Connector status lights, refer to the product

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

What to do:
If this alert persists throughout subsequent drives, schedule service at your earliest convenience. Your vehicle is OK
to drive in the meantime.
This alert is accompanied by a red indicator light on the instrument panel. For more information, see Air Suspension
on page 129.
UI_a006
Service is required
Schedule service now
What this alert means:
This alert is set remotely by Tesla when a condition requiring service is detected on your vehicle.
This alert can be set due to various conditions. When you schedule service, more information should be available.
This alert can only be cleared by a service technician after your vehicle has been serviced.
What to do:
As this alert can be present due to various conditions, it is recommended that you schedule service at your earliest
convenience.
UI_a137
Active service connection to vehicle
Service performing remote diagnostics
What this alert means:
A service technician is remotely logged into your vehicle for diagnosis or repair. You may notice some loss of
Infotainment functionality while the connection persists, but this alert does not indicate an issue with your vehicle.
Your vehicle is OK to drive.
What to do:
This alert should clear automatically after the technician completes vehicle diagnosis or repair. You may find it
necessary to restart your touchscreen to restore full Infotainment functionality after the alert has cleared.For more
information, see Restarting the Touchscreen in your vehicle

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.
What to do:
If this alert is present while you are driving, your vehicle needs to come to a stop as soon as possible. Pull over safely
at your earliest opportunity.
It is recommended that you eliminate or reduce your use of any nonessential features. This can help your vehicle
maintain adequate electrical power for essential functions other than driving, until it can be serviced.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle
may not drive, may shut down unexpectedly, or may not restart.
VCBATT_a402
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 161.
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.
VCBATT_a496
Vehicle is preparing to shut down
PULL OVER SAFELY
What this alert means:
The electrical system cannot provide adequate support to drive or continue driving. Your vehicle is preparing to shut
down to preserve energy for essential functions other than driving.
Your vehicle cannot be driven or continue driving while this condition continues.

This alert indicates that one or more of the tires on your vehicle is extremely low or flat.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is
significantly lower than the recommended cold tire pressure.
What to do:
You should pull over carefully as soon as possible. In a safe location, check for a flat tire.
You can request Tesla roadside assistance options (mobile tire, loaner wheel, tow) if required. See Contacting Tesla
Roadside Assistance on page 201 for more information.
In a non-emergency situation, it is recommended that you visit a local tire shop for assistance or schedule service
using your Tesla Mobile App.
See Maintaining Tire Pressures on page 173 for detailed information on where to find the recommended cold
pressure (RCP) for your vehicle
