Generator not chargingThis symbol comes on during driving if a fault has occurred in the electrical system. Contactan authorized Volvo workshop.
Engine temperatureEngine overheating can result from low oil or coolant levels, towing or hard driving at highheat and altitude, or mechanical malfunction.Engine overheating will be signaled with textand a red warning triangle in the middle of theinstrument display. The exact text will dependon the degree of overheating. It may range from
High engine temp Reduce speed toHigh engine temp Stop engine. If appropri-
ate, other messages, such as Coolant level
low, Stop safely will also be displayed. If
your engine does overheat so that you must stop the engine, always allow the engine tocool before attempting to check oil and cool-ant levels. See Engine compartment – coolant (p. 327) for more information.
Fault in brake systemIf this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe placeand check the level in the brake fluid reser-voir, see Engine compartment – brake fluid(p. 328). If the level in the reservoir is belowMIN , the vehicle should be transported to an
authorized Volvo workshop to have the brakesystem checked. If the
and symbols come on
at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
• If both symbols extinguish, continue driv- ing.
• If the symbols remain on, check the levelin the brake fluid reservoir, see Enginecompartment – brake fluid (p. 328). If thebrake fluid level is normal but the sym-bols are still lit, the vehicle can be driven,with great care, to an authorized Volvoworkshop to have the brake systemchecked.
• If the level in the reservoir is below
MIN,
the vehicle should be transported to anauthorized Volvo workshop to have thebrake system checked.WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a warning mes- sage is displayed in the text window:DO NOT DRIVE . Have the vehicle
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• If the
and symbols
are on at the same time, there is a risk of reduced vehicle stability.
Warning symbolThe red warning symbol lights up to indicate a problem related to safety and/or drivability.A message will also appear in the instrumentpanel. The symbol remains visible until thefault has been rectified but the text messagecan be cleared with the OK button, see Infor-
mation display – menu controls (p. 107). Thewarning symbol can also come on in conjunc-tion with other symbols. Action:
1. Stop in a safe place. Do not drive the vehicle further.
2. Read the information on the display. Implement the action in accordance with the message in the display. Clear themessage using OK.

The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator)may start or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition shouldalways be completely switched off (inmode 0, see Ignition modes (p. 73)) and
there should be no remote keys in the pas-senger compartment. The gear selectorshould be in the P (park) position. If the
engine has been running, wait until it hascooled before touching any components inthe engine compartment. The distributor ignition system operates at very high voltages. Special safety precau-tions must be followed to prevent injury.Always turn the ignition off when:
• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

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. 371).
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.
