Use of AdditivesWith the exception of gas line antifreeze dur- ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.
WARNING
Never carry a cell phone that is switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that could ignite gasoline fumes, resulting infire and injury.
WARNING
Carbon monoxide is a poisonous, color- less, and odorless gas. It is present in allexhaust gases. If you ever smell exhaustfumes inside the vehicle, make sure thepassenger compartment is ventilated, andimmediately return the vehicle to a trainedand qualified Volvo service technician forcorrection.
Opening/closing the fuel filler door
The fuel filler door is located on the right rear fender (indicated by an arrow beside the fueltank symbol on the information display
)
With the ignition switched off, press and release the button on the lighting panel tounlock the fuel filler door. Please note that thefuel filler door will remain unlocked until thevehicle begins to move forward. An audibleclick will be heard when the fuel filler doorrelocks. • If you intend to leave your vehicle while it is being refueled, this feature enables youto lock the doors/tailgate while leavingthe fuel filler door unlocked.
• You can also keep the vehicle locked ifyou remain inside it during refueling. The central locking button does not lock thefuel filler door.
• Be sure the fuel filler door is not obstruc-ted and is completely closed after refuel-ing.
• Open the fuel filler cap slowly during hotweather.
Close the fuel filler door by pressing it; a click indicates that it is closed.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol cancause damage to painted surfaces, whichmay not be covered under the New VehicleLimited Warranty.

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 page 89) and there should be
no remote keys in the passenger compart-ment. The gear selector should be in the P
(park) position. If the engine has been run-ning, wait until it has cooled before touch-ing any components in the engine com-partment. 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.

Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. See page 389 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.
Brake fluid
Location of the brake fluid reservoir
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.
