Introduction to vehicle gas (Bi- Fuel) *
Cars with Bi-Fuel engines can be driven on either vehicle gas or petrol. Vehicle gas can bebiogas or natural gas, or a mixture of the two.Vehicle gas is also called CNG (CompressedNatural Gas).
Methane is the main component in vehicle gas. In natural gas, the methane content varies between85% and 98%. In biogas, the content is almost100%. The tanks for vehicle gas are mounted under the floor in the cargo area and do not affect the nor-mal petrol tank. The system is tested in the same way as for pet- rol cars. The system is closed which means thatleaks are avoided during filling, for example. Thegas tanks are protected and are made to with-stand a collision. The gas is lighter than air, non-toxic and has a higher ignition temperature thanpetrol and diesel. The risk of fire or explosions inthe event of traffic accidents is therefore lowerthan with petrol and diesel. The tank is equipped with a safety valve that allows the gas to evacuate from the tank in theevent of abnormally high pressures. This valveensures that the tank cannot explode.
WARNING
In the event of an accident, the vehicle must be inspected and approved by an authorisedVolvo workshop before it may be used again.Always notify the emergency services on sitethat the vehicle is equipped with a CNG-sys-tem.
WARNING
Smoking and naked flames are prohibited during refuelling, service and repair work. Inthe event of a possible fire, leave the vehicleimmediately and stand a safe distance away. Do not under any circumstances disassemble or adjust the system or its component partsyourself. Carrying out such acts entails risk ofserious personal injury. All service and repairwork must therefore, for safety reasons, onlybe carried out by a trained mechanic - anauthorized Volvo workshop is recommended.
WARNING
If you smell gas in or around the vehicle, switch over to petrol immediately and havethe vehicle checked by the nearest trainedmechanics. If the car is placed in a spray/paint curing booth with a drying temperature higher than60 °C the system pressure must not exceed50 bar, check that the CNG tank is almostempty for this.

INSTRUMENTS AND CONTROLS

Electrical sockets In the tunnel console there are two 12 V electri- cal sockets and one 230 V electrical socket *, in
the cargo area there is one 12 V electricalsocket *.
For the sockets to supply current, the car's elec- trical system must be set in the lowest ignition position I. The sockets are then active as long as
the starter battery level does not become too low. If the engine is switched off and the car is locked, the sockets are deactivated. If the engine isswitched off and the car is not locked, or islocked with blocked lock position temporarilydeactivated, then the sockets continue to beactive for a further ten minutes.
NOTE
Remember that use of the electrical socket with the engine switched off entails a risk ofdischarging the starter battery, which can limitfunctionality.
230 V electrical socket *
230 V electrical socket in tunnel console, rear seat.
The socket can be used for various accessories requiring a 230 V supply, e.g. chargers and lap-top computers.
IMPORTANT
Maximum socket output is 150 W.
Using the socket
1. Pull down the socket cover and insert the
accessory's plug.
> The diode on the socket indicates its sta-tus.
2. Check that the diode is illuminated with a steady green light - only then is current avail- able at the socket. 3. Disconnect the accessory by pulling out the
plug - do not pull on the cable. Pull up the cover when the socket is not being used or the socket is left unattended.
IMPORTANT
• Do not use accessories with large or heavy connectors - they can damage thesocket or come loose when driving.
• Do not use accessories that can causeinterference to the car's radio receiver orelectrical system for example.
• Position the accessory so that it is not atrisk of injuring the driver or passengers inthe event of heavy braking or collision.
• Keep an eye on connected accessoriesas they can generate heat that can burnpassengers or the interior.
WARNING
•
Only use accessories that are undam- aged and fault-free. The accessoriesmust be rated for 230 V and 50 Hz withconnectors designed for the socket. Theaccessories must have a CE marking, ULmarking or an equivalent safety marking.
• Never allow sockets, connectors oraccessories to come into contact withwater or other liquids. Do not touch oruse the socket if it appears to be dam-

When jump starting the car, the following steps are recommended to avoid short circuits or otherdamage:
1. Set the car's electrical system in ignition position 0.
2. Check that the donor battery has a voltage of 12 V.
3. If the donor battery is installed in another car - switch off the donor car's engine and make sure that the two cars do not touch eachother. 4. Connect one of the red jump lead's clamps
to the donor battery's positive terminal (1).
IMPORTANT
Connect the start cable carefully to avoid short circuits with other components in theengine compartment.
5. Open the positive jump-starting point's cover(2).
6. Connect the red jump lead's other clamp onto the car's positive jump-starting point (2).
7. Connect one of the black jump lead's clamps to the donor battery's negative terminal (3).
8. Connect the black jump lead's other clamp onto the car's negative jump-starting point(4).
9. Check that the jump lead clamps are affixed securely so that there are no sparks duringthe starting attempt.
10. Start the engine of the "donor car" and allow it to run a few minutes at a speed slightlyhigher than idle approx. 1500 rpm.

STARTING AND DRIVING
407
•
Brake now and again to remove any layer of salt. Make sure that other road users are notput at risk by the braking.
• Gently depress the brake pedal after finish-ing driving and before starting your next trip.
MaintenanceTo keep the car as safe and reliable as possible,follow the Volvo service intervals as specified inthe Service and Warranty Booklet. New and replaced brake linings and brake discs do not provide optimal braking effect until theyhave been "worn in" a few hundred kilometres.Compensate for the reduced braking effect bydepressing the brake pedal harder. Volvo recom-mends only fitting brake linings that are approvedfor your Volvo.
IMPORTANT
The wear on the brake system's components must be checked regularly. Contact a workshop for information about the procedure or engage a workshop to carry outthe inspection - an authorised Volvo work-shop is recommended.
