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.

Indicator symbols in the driver display The indicator symbols alert the driver that a func- tion is activated, that a system is operating, orthat a fault or abnormal condition exists.
SymbolSpecification
Information, read display text When one of the car's systems does not behave as intended, thisinformation symbol illuminates anda text appears on the driver display.The information symbol can alsoilluminate in conjunction with othersymbols.
Fault in brake system The symbol lights up when there is a fault in the parking brake.

SymbolSpecification
Automatic brake on The symbol illuminates when the function is activated and the footbrake or parking brake is acting.The brake holds the car stationarywhen it has stopped.
Tyre pressure system The symbol illuminates when tyre pressure is too low. If there is afault in the tyre pressure system,the symbol will flash for approx. 1minute and then illuminate with aconstant glow. This may bebecause the system cannot detector warn of low tyre pressure asintended.
Emissions system If the symbol illuminates after the engine has been started then itmay be due to a fault in the car'semissions system. Drive to a work-shop for checking. Volvo recom-mends that an authorised Volvoworkshop is contacted.
Symbol Specification
Left and right-hand direction indicator The symbols flash when the direc- tion indicators are used.

If thesymbol illuminates and the oil levelis normal, contact a workshop.Volvo recommends that an author-ised Volvo workshop is contacted.
Alternator not charging This symbol illuminates during driv- ing if a fault has occurred in theelectrical system. Visit a workshop.Volvo recommends that an author-ised Volvo workshop is contacted.

Outside temperature gauge
The outside temperature gauge is shown in the driver display.
A sensor detects the temperature outside of the car.
Outside temperature gauge location in the 12-inch and 8-inch driver display.
If the car has been stationary, the gauge may dis- play a temperature reading that is too high. When the outside temperature is within the range +2°C to -5°C, a snowflake symbol is shown in thedriver display as a warning for potentially slipperyconditions. The snowflake symbol is also illumi-nated briefly in the head-up display, if the car isequipped with one.

CLIMATE CONTROL
* Option/accessory.213
Heater*
The heater helps the engine and passenger compartment reach the correct temperaturebefore and during driving.
The heater has two subfunctions: • Parking heater - heats the engine and pas- senger compartment, if necessary, when the parking climate control's preconditioning
* is
activated.
• Additional heater - heats the passenger compartment and engine, if necessary, dur-ing driving.
The heater is fuel-driven and is fitted in the frontright-hand wheel housing.
This symbol illuminates in the driverdisplay when the heater is active.
NOTE
When the heater is running, smoke may be emitted from the right-hand front wheel hous-ing and a low hum may be heard. A tickingsound from the fuel pump may also be heardfrom the rear section of the car. This is per-fectly normal.
Battery and chargingThe heater is powered by the car's starter battery. If the charge level of the starter battery is too low,then the heater is switched off automatically andthe driver display shows a message.
NOTE
Make sure that there is enough charge in the battery if the heater needs to be used.
Fuel and refuelling 6
Warning label on fuel filler flap.
The heater uses fuel from the car's normal fuel tank. If the car is parked on a steep hill, the front of the car should point downhill to ensure that there is asupply of fuel to the heater. If the level in the fuel tank is too low then theheater is switched off automatically and the driverdisplay shows a message.
NOTE
Make sure there is enough fuel in the car's normal fuel tank if the heater needs to beused.
WARNING
Fuel which spills out could be ignited. Switch off the fuel-driven heater before starting torefuel. Check in the driver display that the heater is switched off. The heat symbol is shown whenit is operating.

LOADING AND STORAGE
* Option/accessory.
220
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-
