Start battery
The vehicle has a single-pole electrical system that uses the chassis and engine mount as con-ductors. The start battery is used to start the electrical system and power the starter motor and otherelectrical equipment in the vehicle. The start battery should only be replaced by a workshop 18
.
The vehicle has a voltage-regulated alternating current generator. The starter battery is a 12 V battery, designed for the carbon dioxide reducing functions Start/Stopand regenerative charging, and to support thefunctionality of the car's different systems. The service life and performance of the start bat- tery are affected by factors such as driving style,driving conditions, climate, battery discharges,number of starts, etc.
• Never disconnect the start battery while theengine is running.
• Make sure the cables to the start battery arecorrectly connected and the clamps aresecurely tightened.
WARNING
•Batteries generate hydrogen gas, which is flammable and explosive.
• Do not connect the jumper cable to anypart of the fuel system or to any movingparts. Avoid touching hot manifolds.
• Battery fluid contains sulfuric acid. Do notallow battery fluid to contact eyes, skin,fabrics or painted surfaces.
• If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
• Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.
Connection points
WARNING
PROPOSITION 65 WARNING Battery posts, terminals, and related accesso- ries contain lead and lead compounds, chemi-cals known to the state of California to causecancer and reproductive harm. Wash handsafter handling. Use the vehicle's connection points in the engine compartment to connect an external start batteryor battery charger. The battery terminals on the car's starter battery in the luggage/cargo area must
not be used.
If the start battery is being charged, the support battery will also be charged.

CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery and support battery. The rapidcharging function should not be used as thiscould damage the battery.
CAUTION
Failure to observe the following could cause the infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
• The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too many times, it will shorten its service life. The service life of the starter battery is affec- ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging. A starter battery that is always kept fully charged has the maximum service life.
Location
The start battery is located in the cargo compartment.
WARNING
If the starter battery is disconnected, the func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
