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
The electrical functions in the car load the starter battery to varying degrees. Avoid using the ignition position II when the car is switched off. Instead, use ignition position I - which uses less power.
Using jump starting with another battery
If the starter battery is discharged then the car can be started with current from another battery.
A used starter battery or support battery must be recycled in an environmentally sound manner.
Symbols on the batteries
There are information and warning symbols on the batteries.
The starter battery is used to start up the electrical system and drive the starter motor as well as other electrical equipment in the car.
Cars with the start/stop function are equipped with two batteries - one more powerful 12 V starter battery for starting and one support battery that helps during the function's starting sequence.
