Location of the filler cap and dipstick
NOTE
Before checking the oil: •The car should be parked on a level surface.
• If the engine is warm
, wait for at least
10 – 15 minutes after the engine hasbeen switched off.
G021737
The oil level must be between the MIN and MAX
marks on the dipstick
Checking the oil1. Pull out the dipstick and wipe it with a
lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level. The level must be between the MIN and MAX marks.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately
0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if necessary until the level is near the MAX
mark.
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.

Message
Oil level
The oil level can be checked when the engine is not running by scrolling to the oil level sen-sor using the thumb wheel on the left steeringwheel lever.
CAUTION
• If Oil service required is displayed,
the oil level may be too high. Take the vehicle to an authorized Volvo work-shop as soon as possible.
• If the oil level sensor indicates that thelevel is too low, using the correct oil,top up with the amount of oil indicatedas soon as possible, see oil specifica-tions (p. 359).
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
Electronically checking the oil levelThe oil level should be checked at regular intervals, particularly during the period up tothe first scheduled maintenance service. To check the oil level:
1. Activate ignition mode
II, see Ignition
modes (p. 73).
2. Turn the thumb wheel on the left steering wheel lever until
Oil level is displayed.
> The oil level will be displayed.
NOTE
• The system cannot detect changes in the oil level immediately. The vehiclemust be driven approximately 20 miles(30 km) or have been parked on levelground with the engine off for5 minutes before the oil level readingwill be correct.
• If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked on an incline, etc.),
No values availablewill be displayed. This does
not indi-
cate a problem with the oil level sen- sor.
Engine compartment – coolant
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo service tech-nician.

CAUTION
•If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
WARNING
•Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
Engine compartment – brake fluid
The brake fluid should always be between the MIN
and MAX marks on the inside of the res-
ervoir.

318
Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed. Check, without removing the cap, that there is sufficient fluid in the reservoir. Fluid type: DOT 4 boiling point >536 °F
(>280 °C).Replace : The fluid should be replaced
according to the intervals specified in the Warranty and Service Records Informationbooklet. When driving under extremely hard condi- tions (mountain driving, etc), it may be neces-sary to replace the fluid more often. Consult atrained and qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a brake-related message is shown in the informationdisplay: DO NOT DRIVE . Have the car
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the
fluid. The level must be between the MIN
and MAX marks.
Engine compartment – power steering fluid
The fluid level must be between the MIN and
MAX marks. For capacities and recom-
mended fluid grade, see Fuel tank volume – specification and volume (p. 362).
Check the level frequently. It does not nor- mally require changing.
WARNING
If a problem should occur in the power steering system or if the vehicle has noelectrical current and must be towed, it isstill possible to steer the vehicle. However,keep in mind that greater effort will berequired to turn the steering wheel.

Battery – handling
The battery's service life is affected by the number of starts, if it has been discharged,driving style, driving conditions, weather con-ditions ,etc.
Handling
• Check that the battery cables are cor- rectly connected and tightened.
• Never disconnect the battery when theengine is running (for example, whenreplacing the battery).
• If the battery is fully discharged a numberof times, this may shorten its service life.
• The service life of a battery is affected byfactors such as the number of starts, driv-ing conditions and climate. Extreme coldmay also further decrease the battery’sstarting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
• Never use a quick charger to charge thebattery. Only traditional types of batterychargers should be used.

CAUTION
The infotainment system's energy-saving feature may not function correctly or at all,and/or a message may be displayed if abattery charger or jumper cables are notconnected properly.
• The negative terminal on the battery must
never be used to connect a
jumper cable or a battery charger.Only the ground point on the chassismay be used.
See Jump starting (p. 237) for an illustra- tion and additional information.
WARNING
• Never expose the battery to open flame or electric spark.
• Do not smoke near the battery.
• Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces. Ifcontact occurs, flush the affected areaimmediately with water. Obtain medi-cal help immediately if eyes are affec-ted.
NOTE
The life of the battery is shortened if it becomes discharged repeatedly.

Proper battery maintenance can help prolong its service life.
Maintenance
• Use a screw driver to open the caps or cover and a flashlight to inspect the level.
• If necessary, add distilled water. The levelshould never be above the indicator.
• The fluid level should be checked if thebattery has been recharged.
• After inspection, be sure the cap overeach battery cell or the cover is securelyin place.
• Check that the battery cables are cor-rectly connected and properly tightened.
• Never disconnect the battery when theengine is running, or when the key is inthe ignition. This could damage the vehi-cle's electrical system.
• The battery should be disconnected fromthe vehicle when a battery charger isused directly on the battery.
• To help keep the battery in good condi-tion, the vehicle should be driven for atleast 15 minutes a week or connected toa charger with an automatic chargingfunction.
• If the battery is fully discharged a numberof times, this may shorten its service life.Keeping the battery fully charged helpsprolong its service life.
