Start battery
This battery powers the vehicle's primary electrical system, which includes electrical equipment and engine start. If the vehicle is a mild hybrid1, the engine is instead started by the support battery.
The start battery is a 12 V battery that is dimensioned to power the vehicle's specific electrical systems and functions.
- Never disconnect the start battery while the engine is running.
- Make sure the cables to the start battery are correctly connected and the clamps are securely tightened.

Warning
- Batteries generate hydrogen gas, which is flammable and explosive.
- Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot manifolds.
- Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces.
- If contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
- Never expose the battery to open flame or electric spark. Do not smoke near the battery. Failure to follow the instructions for jump starting can lead to injury.
Starter battery service life and capacity
The service life of the start battery is influenced by a number of factors, including the number of starts, discharges, driving style, driving conditions and climate conditions. The starting capacity of the battery decreases gradually over time and therefore needs to be charged if the vehicle is not used for a prolonged period of time or if it is only driven short distances. Severe cold further limits starting capacity. If the starter battery becomes discharged too many times, its service life will be shortened.
To keep the start battery in good condition, drive the vehicle at least 15 minutes a week or connect the battery to a battery charger with automatic maintenance charging. A starter battery that is always kept fully charged has the maximum service life.
