Status to display the oil level.
Oil level graphic in the center display.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The vehiclemust have been driven approximately30 km (20 miles) and have been stationary5 minutes on a level surface and with theengine off before the correct oil level willbe displayed.
NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engineshutdown, vehicle inclination, ambient temperature, etc.) the message
No value
available will be shown in the center dis-
play. This does not mean that anything is
wrong in the vehicle systems.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

MAINTENANCE AND SERVICE

Coolant expansion tank, left-hand drive vehicle.
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should notexceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in thereverse order.
CAUTION
Do not ingest the contents. May cause damage to organs (kidneys).
Use premixed coolant according toVolvo's recommendations. If concen-trated coolant is used, make sure thatthe coolant mixture is 50% coolantand 50% water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use newcoolant when replacing larger compo-nents in the cooling system.
Never run the engine unless the cool-ing system is properly filled. Animproperly filled cooling system couldlead to high temperatures and cracksin the cylinder heads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Coolant specifications
Recommended grade: Volvo-approved pre-
mixed coolant. If concentrated coolant is used, mix with 50% water of acceptablequality (i.e. not salt water, etc.). Consult aVolvo retailer if you have any questions.
To avoid deterioration of the cooling system, engine trouble, etc., only approved Volvo cool-ant should be used.
WARNING
Coolant is hazardous if ingested and could cause damage to organs (kidneys). Theproduct contains ethylene glycol, inhibitor,water, etc.

Transmission fluid specifications
Under normal driving conditions, the trans- mission fluid will not need to be changed dur-ing the transmission's service life. However,it may need to be changed if the vehicle isdriven frequently in adverse driving condi-tions.
Automatic transmission
Prescribed transmission fluid: AW-1

Type designations (p. 610)
Brake fluid specifications
The medium in the hydraulic brake system is called brake fluid and is used to transfer brak-ing force from e.g. pressure on the brakepedal via a master brake cylinder to one ormore slave cylinders, which in turn act on amechanical brake.
Recommended grade: Volvo Original or simi-
lar fluid that meets a combination of Dot 4, 5.1 and ISO 4925 class 6.
NOTE
Changing or filling brake fluid should be entrusted to an authorized Volvo work-shop.
