Engine oil
An approved engine oil must be used in order that the recommended service intervals can beapplied.
Volvo recommends:
IMPORTANT
In order to fulfil the requirements for the engine's service intervals all engines are filledwith a specially adapted synthetic engine oilat the factory. The choice of oil has beenmade very carefully with regard to service life,starting characteristics, fuel consumption andenvironmental impact. An approved engine oil must be used in order that the recommended service intervals canbe applied. Only use a prescribed grade of oilfor both filling and oil change, otherwise thereis a risk of the service life, starting characte-ristics, fuel consumption and environmentalimpact of the car being affected. If engine oil of the prescribed grade and vis- cosity is not used, engine related componentsmay become damaged. Volvo Car Corporationdisclaims any liability for any such damage. Volvo recommends that oil changes are car- ried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/ high oil level or low oil pressure. Certain enginevariants have an oil pressure sensor, and then thedriver display's warning symbol for low oil pres- sure
is used. Other variants have an oil
level sensor, when the driver is informed via the driver display's warning symbol
and display texts. Certain variants have both systems. Contact a Volvo dealer for more information. Change the engine oil and oil filter in accordance with the intervals specified in the Service andWarranty Booklet. Using oil of a higher than specified grade is per- mitted. If the car is driven in adverse conditions,Volvo recommends using an oil of a higher gradethan the one specified.

Topping up coolant
The coolant cools the internal combustion engine to the correct operating temperature. Theheat that is transferred from the engine to thecoolant can be used to heat the passenger com-partment.
When topping up the coolant, follow the instruc- tions on the packaging. Never top up with wateronly. The risk of freezing increases with both toolittle and too much coolant concentrate.
WARNING
Coolant can be very hot. If the coolant requires topping up when the engine is atoperating temperature, unscrew the expan-sion tank cap slowly to gently release theoverpressure.
Coolant expansion tank, left-hand drive car.
Screw off the cap in the plastic cover.
Screw off the cap on the expansion tank and top up with coolant. The coolant level must not exceed the yellow MAX mark inside the
expansion tank.
Reinstall the parts in reverse order.

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.

Replacing a fuse All electrical functions and components are pro- tected by a number of fuses in order to protectthe car's electrical system from damage by shortcircuiting or overloading.
Changing1. Look in the fuse diagram to locate the fuse.
2. Pull out the fuse and check from the side tosee whether the curved wire has blown.
3. If this is the case, replace it with a new fuse of the same colour and amperage.
WARNING
Never use a foreign object or a fuse with an amperage higher than that specified whenreplacing a fuse. This could cause significantdamage to the electrical system and possiblylead to fire.

Cleaning the exterior
The car should be washed as soon as it becomes dirty. This means that the car is easierto clean since the dirt does not attach as firmly.It also reduces the risk of scratches and keepsthe car fresh. Wash the car in a car wash with oilseparator. Use car shampoo.
Handwashing
• Remove bird droppings from the paintwork as soon as possible. Bird droppings containchemicals that affect and discolour paintworkvery quickly. For example, use soft paper orsponge soaked in plenty of water. An author-ised Volvo workshop is recommended for theremoval of any discoloration.
• Hose down the underbody.
• Rinse the entire car until the dissolved dirthas been removed so as to reduce the risk ofscratches from washing. Do not spray directlyonto the locks.
• If necessary, use cold degreasing agent onvery dirty surfaces. Note that in this case, thesurfaces must not be hot from the sun.
• Wash using a sponge, car shampoo andplenty of lukewarm water.
• Clean the wiper blades with a lukewarm soapsolution or car shampoo.
• Dry the car using a clean, soft chamois or awater scraper. If you avoid allowing drops ofwater to dry in strong sunlight, you reduce the risk of water drying stains which mayneed to be polished out.
WARNING
Always have the engine cleaned by a work- shop. There is a risk of fire if the engine is hot.
IMPORTANT
Dirty headlamps have impaired functionality. Clean them regularly, e.g. when refuelling. Do not use any corrosive cleaning agents but use water and a non-scratching spongeinstead.
NOTE
Outside lighting such as headlamps and rear lamps may temporarily have condensation onthe inside of the lens. This is normal, all exte-rior lighting is designed to withstand this.Condensation is normally vented out of thelamp housing when the lamp has beenswitched on for a time.
Automatic car washAn automatic car wash is a simple and quick way of washing the car, but it cannot reach every-where. Washing the car by hand is recommendedto achieve a good result, or to supplement auto-matic car washes with washing by hand.
NOTE
The car must only be washed by hand over the first few months. This is because the paintis more delicate when it is new.
IMPORTANT
Before driving the car into an automatic car wash, deactivate the functions for Automaticbraking when stationary (Auto Hold) andAutomatic application of parking brake. Ifthese functions are not deactivated, the brakesystem will jam when the car is stationary andthe car will not be able to move.
In car washes where the car is towed through with rolling wheels, the following applies:
1. Drive into the automatic car wash.
2. Deactivate the function for automatic braking
when stationary (Auto Hold) using the switch in the tunnel console.
3. Deactivate the function for automatic appli- cation of parking brake via the centre display.
4. Move the gear lever to position N.

knob in the tunnel console to STOP. Hold
the knob in STOP position for at least
4 seconds.
> The car is ready for the automatic car wash.
IMPORTANT
The system will automatically switch to P
mode unless the above step is followed. The wheels are locked in P mode, which they
should not be when putting the car through an automatic car wash.
High-pressure washingWhen using high-pressure washing, use sweep- ing movements and make sure that the nozzledoes not come closer than 30 cm to the surfaceof the car. Do not spray directly onto the locks.
Testing the brakesLightly depress the brake pedal now and thenwhen driving long distances in rain or slush. Theheat from the friction causes the brake linings towarm up and dry. Do the same thing after startingin very damp or cold weather.
WARNING
Always test the brakes after washing the car, including the parking brake, to ensure thatmoisture and corrosion do not attack thebrake linings and reduce braking perform-ance.
Wiper bladesAsphalt, dust and salt residue on wiper blades, as well as insects, ice etc. on the windscreen, impairthe service life of wiper blades. When cleaning, set the wiper blades in service position.
NOTE
Wash the wiper blades and windscreen regu- larly with lukewarm soap solution or carshampoo. Do not use any strong solvents.
Exterior plastic, rubber and trim components
A special cleaning agent available from Volvo dealers is recommended for the cleaning andcare of coloured plastic parts, rubber and trimcomponents, e.g. glossy trim mouldings. Whenusing such a cleaning agent the instructionsmust be followed carefully. The frames around the side windows, the car's roof rails and the door frames at the windows *
are produced in anodised aluminium. This means that they should only be washed using a cleaning agent with a pH value between 3.5 and 11.5.This is in order to avoid discolouration.
Parts that should be washed using a cleaning agent with a pH value between 3.5 and 11.5.
IMPORTANT
Avoid waxing and polishing on plastic and rubber. When using degreasant on plastic and rubber, only rub with light pressure if it is necessary.Use a soft washing sponge. Polishing glossy trim mouldings could wear away or damage the glossy surface layer. Polishing agent that contains abrasive must not be used.
