Replacing the battery in the remote control key
The battery in the remote control key needs to be replaced when it has become discharged.
Overloading the starter battery
High power consumption without the car being able to charge the starter battery leads to low State of Charge (SoC) and some electric functions being reduced or switched off. If the State of Charge (SoC) decreases to below a certain limit, it is no longer possible to start the car without jump starting or charging with an external charger.
Using jump starting with another battery
If the starter battery is discharged then the car can be started with current from another battery.
The car's own power supply is connected to several different components and activates their electrical functions.
Recycling the batteries
Used batteries must be recycled in an environmentally sound manner.
Symbols on the batteries
There are information and warning symbols on the batteries.
This battery powers the car's primary electrical system, which includes the electrical equipment and starting the engine. If the car is the mild hybrid* type, the engine is instead started by the support battery.
The car is equipped with a support battery that helps during the Start/Stop function's starting sequence.
