Replacing a wiper blade
The wiper blades sweep water away from the windscreen and rear window. Together with thewasher fluid they clean the windows and ensurevisibility for driving. Windscreen and rear windowwiper blades can be replaced.
Replacing a windscreen wiper blade
Fold up the wiper arm when it is in service position. Press the button located on thewiper blade mounting and pull straight outparallel with the wiper arm.
Slide in the new wiper blade until a "click" is heard.
Check that the blade is firmly installed.
4. Fold the wiper arm back towards the wind- screen.
The wiper blades are different lengths.
NOTE
The wiper blades are different lengths. The blade on the driver's side is longer than onthe passenger side.

Replacing the wiper blade, rear window
1. Fold out the wiper arm.
2. Grip the inner section of the blade (by thearrow).
3. Turn anticlockwise to use the blade's end position against the wiper arm as a lever to detach the blade more easily.
4. Press the new wiper blade into place. You should hear a click. Check that it is firmlyinstalled.
5. Lower the wiper arm.
IMPORTANT
Check the blades regularly. Neglected main- tenance shortens the service life of the wiperblades.

Starter battery
The electrical system is single-pole and uses the chassis and engine casing as a conductor. The starter battery is used to start up the electri- cal system and drive the starter motor as well asother electrical equipment in the car. The starter battery should be replaced by a workshop 13
.
The car has a voltage-regulated AC alternator. The starter battery is a 12 V AGM battery, designed for the carbon dioxide reducing func-tions, Start/Stop and regenerative charging, andto support the functionality of the car's differentsystems. The service life and function of the starter battery is influenced by factors such as the number ofstarts, discharging, driving style, driving condi-tions, climatic conditions etc. • Never disconnect the starter battery when the engine is running.
• Check that the cables to the starter batteryare correctly connected and properly tight-ened.
WARNING
•
The battery can generate oxyhydrogen gas, which is highly explosive. A spark canbe formed if a jump lead is connectedincorrectly, and this can be enough forthe battery to explode.
• The battery contains sulphuric acid, whichcan cause serious burns.
• If sulphuric acid comes into contact witheyes, skin or clothing, flush with largequantities of water. If acid splashes intothe eyes - seek medical attention imme-diately.
When connecting an external starter battery orbattery charger, use the car's charging points inthe engine compartment. The battery terminalson the car's starter battery in the cargo area must not be used.
During charging, both the starter battery and the support battery are charged.
13 An authorised Volvo workshop is recommended.

Positive charging point
Negative charging point
IMPORTANT
When charging the starter battery and the support battery, only use a modern batterycharger with controlled charging voltage. Fastcharging function must not be used since itmay damage the battery.
IMPORTANT
If the following instruction is not observed then the energy saving function for infotain-ment may be temporarily disengaged, and/orthe message in the driver display about thestarter battery's state of charge may be tem-porarily inapplicable, following the connectionof an external starter battery or batterycharger:
• The negative battery terminal on the car's starter battery must
never be used for
connecting an external starter battery orbattery charger - only the car's negative
charging point may be used as the
grounding point.
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 and cli-mate. Battery starting capacity decreasesgradually with time and therefore needs to berecharged if the car is not used for a longertime or when it is only driven short distances.Extreme cold further limits starting capacity. To maintain the battery in good condition, at least 15 minutes of driving/week is recom-mended or that the battery is connected to abattery charger with automatic trickle charg-ing. A battery that is kept fully charged has a maximum service life.

IMPORTANT
When replacing the starter battery or support battery, a battery of AGM 15
type must be fit-
ted.
NOTE
• The higher the current take-off in the car, the more the alternator must be workingand the batteries charging = Increasedfuel consumption.
• When the capacity of the starter batteryhas fallen below the lowest permissiblelevel then the Start/Stop function is dis-engaged.
Temporarily reduced Start/Stop function due to high current take-off means: •
The engine starts automatically 16
without the
driver depressing the clutch pedal (manualgearbox).
• The engine starts automatically without thedriver lifting his/her foot off the foot brakepedal (automatic gearbox).
The support battery normally requires no moreservice than the normal starter battery. A work-shop should be contacted in the event of ques-tions or problems - an authorised Volvo workshopis recommended.
IMPORTANT
If the following instruction is not observed then the Start/Stop function may temporarilycease to work after the connection of anexternal starter battery or battery charger:
• The negative battery terminal on the car's starter battery must
never be used for
connecting an external starter battery orbattery charger - only the car's negative
charging point may be used as the
grounding point.
NOTE
If the starter battery has been discharged so much that the car has no normal electricalfunctions and the engine is then jump-startedwith an external battery or a battery charger,the Start/Stop function will continue to beactivated. If the Start/Stop function thenauto-stops the engine shortly after, there is agreat risk that engine auto-start will fail dueto insufficient battery capacity, because thebattery has not had the opportunity torecharge. If the car has been jump-started, or if there is insufficient time to charge the battery with abattery charger, the recommendation is totemporarily deactivate the Start/Stop functionuntil the battery has been recharged by thecar. In an outside temperature of +15 °C, thebattery needs to be charged for at least1 hour by the car. In a lower outside tempera-ture, the charging time may increase to3-4 hours. The recommendation is to chargethe battery using an external battery charger.
