Running Out of Range
CAUTION: It is your responsibility to monitor the state of the high voltage Battery and the remaining range of your
vehicle. Do not assume that there is any range available when the range displayed on the instrument clustertouchscreen
is at 0 miles (0 km) (or 0%). Damage to the low voltage battery due to running out of range is not covered by the
warranty.
NOTE: In the unlikely event your vehicle runs out of range while driving, pull over when safe to do so and contact Tesla
Roadside Assistance on page 588 or your preferred tow provider.
If CybertruckModel SModel X runs out of range, the low voltage battery is no longer supported – and when low voltage is not
supported, the vehicle cannot charge. Therefore, the low voltage battery must be supported by an external power supply to
allow you to charge the High Voltage (HV) Battery. Once the vehicle begins charging, the external power supply is no longer
required.
If CybertruckModel SModel X runs out of range, the low voltage system is no longer supported – and when the low voltage
battery runs out of power, the vehicle cannot charge. Therefore, the low voltage system must be supported by an external
power supply to allow you to charge the High Voltage (HV) Battery. Once the vehicle begins charging, the external power
supply is no longer required.
In the case of running out of range away from a charger, the tow provider should transport CybertruckModel SModel X to the
nearest charging station and unload the vehicle within the charging cable's reach. Once the vehicle is positioned next to a
charger, follow these instructions:
NOTE: If the vehicle is being transported to a charger, make sure the tow provider does not leave until confirming that the
vehicle's high voltage Battery is successfully charging.
1. Jump start the low voltage system (see Jump Starting on page 595Jump Starting on page 1066). The low voltage battery
must be jump started to support the high voltage Battery.
2. Wait a few minutes. Once the touchscreen powers on, plug the charge cable into CybertruckModel SModel X to begin
charging the high voltage Battery.
3. When CybertruckModel SModel X begins to charge, disconnect the external power supply from the low voltage battery
jump posts.
WARNING: Shut off the external power supply before removing either cable. Removing the cables while the external
power source is active may cause arcing.
NOTE: If CybertruckModel SModel X is still not able to shift into Drive after charging the high voltage Battery, the low
voltage battery may need additional time to recover. Reconnect the charge cable, wait several minutes, disconnect the
charge cable, and then try again.
Before transporting to a non-Tesla charger, ensure your vehicle is equipped with an adapter that accommodates the specific
type of charging station you will be using. Even at a non-Tesla charger, you will need to jump start the low voltage system
before you can begin charging.
CAUTION: Always ensure CybertruckModel SModel X has enough range for your drive, or for being stored for an
extended period. Do not rely on the range estimates displayed on the touchscreen or mobile app as range can decrease
faster than projected due to ambient temperature, driving habits, wind, vehicle settings (such as Sentry Mode), etc.
NOTE: Towing your vehicle as a result of running out of range is not covered by the warranty.
