car.
14.3. Powerless or unresponsive car
If your car is unresponsive or appears to have no power, the cause could be flat batteries or something
affecting its electrical systems.
If your car's batteries are flat, the car will not respond to some of your actions. This includes trying to unlock or start it.
If your car doesn't respond due to low power, there are several recovery options depending on the situation.
The following situations can lead to both batteries in your car going flat:
The car is driven to 0% battery level and is then not immediately recharged.
The car is left with a low battery level. If not plugged in for charging, the battery level drops further as the car uses a small
amount of power while parked.
The car is left without being charged for a long time, which allows the battery level to drop.
Low temperatures temporarily reducing battery capacity below the required level to keep your car powered.
Conditions or uses that increase power consumption and result in a faster-than-expected drop in battery level include:
Use of accessories or power-consuming car functions.
High temperatures triggering battery cooling.
Recovery from a flat traction battery
If only the traction battery is flat, the car's systems have power but it can't be started or driven. Your car shows that the battery
level is at 0%. In this situation, the 12 V battery can power the systems needed to initiate charging of the traction battery. It's
important to conserve energy in the 12 V battery so that you can access and charge your car.
Car recovery actions:
If you can charge your car where it's parked, do so immediately.
If your car can't be charged at your current location, have the car recovered and transported to a charging source. In the
meantime, try to conserve the remaining power in the 12 V battery. This is important for battery health, but also keeps
essential functionality available for you to use in an emergency.
Recovery from total loss of power
If the 12 V battery goes flat, your car will be completely unresponsive. This can happen if something prevents the traction bat-
tery from keeping the 12 V battery charged, such as allowing the traction battery to go flat and then not charging the car in time.
