Battery
The service life and function of the battery is influenced by factors such as the number ofstarts, discharging, driving style, driving con-ditions, climatic conditions etc. The starter battery is a traditional 12 V bat- tery.
• Never disconnect the battery when the engine is running.
• Check that the cables to the battery arecorrectly connected and properly tight-ened.
WARNING
•The battery can generate oxyhydrogen gas, which is highly explosive. A sparkcan be formed if a jump lead is con-nected incorrectly, and this can beenough for the battery to explode.
• The battery contains sulphuric acid,which can cause serious burns.
• If sulphuric acid comes into contactwith eyes, skin or clothing, flush withlarge quantities of water. If acidsplashes into the eyes - seek medicalattention immediately.
IMPORTANT
Only a traditional battery charger should ever be used when charging the battery.

IMPORTANT
If the following instruction is not observed then the energy saving function for info-tainment may be temporarily disengaged,and/or the message in the information dis-play about the main battery's state ofcharge may be temporarily inapplicable,following the connection of an externalbattery or battery charger:
• The negative battery terminal on the car's starter battery must
never be
used for connecting an external bat-tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting with battery (p. 270) for a description of how the cable clampsmust be attached.
NOTE
The life of the battery is shortened if it becomes discharged repeatedly. The life of the battery is affected by several factors, including driving conditions andclimate. Battery starting capacity decrea-ses gradually with time and thereforeneeds to be recharged if the car is notused for a longer time or when it is onlydriven short distances. Extreme cold fur-ther limits starting capacity. To maintain the battery in good condition, at least 15 minutes of driving/week is rec-ommended or that the battery is con-nected to a battery charger with automatictrickle charging. A battery that is kept fully charged has a maximum service life.

Starter battery - replacement
The starter battery in the car can be replaced without the help of a workshop. The starter battery is a traditional 12 V bat- tery.
RemovalFirst of all
: Take the remote control key from
the ignition switch and wait at least 5 minutesbefore any electrical connections are touched- this is because the car's electrical systemneeds to store the necessary information tocontrol modules.
Open the clips on the front cover and remove the cover.
Release the rubber moulding so that the rear cover is free.

IMPORTANT
When replacing batteries in cars with the Start/Stop function, the AGM 12
type bat-
teries must be fitted.
NOTE
• The higher the current take-off in the car (extra cooling/heating, etc.) themore the batteries must be charged =increased fuel consumption.
• When the capacity of the battery hasfallen below the lowest permissiblelevel then the Start/Stop function isdisengaged.
Temporarily reduced Start/Stop function due to high current take-off means: •
The engine starts automatically 13
without
the driver depressing the clutch pedal (manual gearbox).
• The engine starts automatically withoutthe driver lifting his/her foot off the footbrake pedal (automatic gearbox).

Location of the batteries
A: Left-hand drive car. B: Right-hand drive car. (1) Starter battery14
(2) Support battery.
The support battery normally requires no more service than the normal battery used forstarting. A workshop should be contacted inthe event of questions or problems - anauthorised Volvo workshop is recommended.
IMPORTANT
If the following instruction is not observed then the Start/Stop function may tempo-rarily cease to work after the connection ofan external battery or battery charger:
• The negative battery terminal on the car's starter battery must
never be
used for connecting an external bat-tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting with battery (p. 270) for a description of how the cable clampsmust be attached.
NOTE
If the battery has become so discharged that everything is "black" and in principlethe car does not have all the normal elec-trical functions and the engine is subse-quently started using an external battery orbattery charger, then the Start/Stop func-tion will be activated. It will then be possi-ble for the engine to be auto-stopped butin the event of an auto-stop the Start/Stopfunction may fail to auto-start the enginedue to inadequate capacity in the battery. The battery must first be charged in order to ensure a successful auto-start after anauto-stop. At an outside temperature of+15 °C the battery needs to be charged forat least 1 hour. At a lower outside tem-perature a charging time of 3-4 hours isrecommended. The recommendation isthat the battery is charged using an exter-nal battery charger. If this is not possible then the recommen- dation is to temporarily deactivate theStart/Stop function until the battery hasbeen adequately recharged. For more information on charging the starter battery, see Battery (p. 361).
