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.

Location of the coolant reservoir
See Fuel tank volume – specification and vol- ume (p. 362) for information on cooling sys-tem capacities.

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.
