STARTING AND DRIVING

Diesel Diesel is a type of engine fuel that is intended for cars with a diesel engine.
Only use diesel fuel from well-known producers. Never use fuel of dubious quality. Diesel fuelmust fulfil the EN 590 or SS 155435 standard.Diesel engines are sensitive to contaminants inthe fuel, such as excessively high volumes of sul-phur and metals. At low temperatures (lower than 0 °C) a paraffin precipitate may form in the diesel fuel, which maylead to ignition problems. The fuel qualities thatare sold must be adapted for season and climatezone, but for extreme weather conditions, old fuelor moving between climate zones, paraffin precip-itate may occur. The risk of condensation in the fuel tank is reduced if the tank is kept well filled. When refuelling, check that the area around the fuel filler pipe is clean. Avoid spilling fuel onto thepaintwork. Wash off any spillage with detergentand water.
IMPORTANT
Diesel fuel must: •fulfil the EN 590 and/or SS 155435 standards
• have a sulphur content not exceeding10 mg/kg
• have a maximum of 7 vol % FAME 15
(B7).
IMPORTANT
Diesel type fuels that must not be used:
• Special additives
• Marine diesel fuel
• Heating oil
• FAME 16
and vegetable oil.
These fuels do not fulfil the requirements in accordance with Volvo recommendations andgenerate increased wear and engine damagethat is not covered by the Volvo warranty.

Empty tank and diesel engine
Once the engine has stopped due to fuel starva- tion, the fuel system needs a few moments tocarry out a check.
Before starting the engine after the fuel tank has
been filled with diesel - proceed as follows:
1. The remote control key must be inside the car.
2. Set the car in ignition position II - turn the
ignition dial to START without depressing
the brake pedal and hold the knob in the START position for approx. 4 seconds. Then
release the knob, which automatically returns to its starting position.
3. Wait approx. one minute.
4. To start the engine: Depress the brake pedal and turn the ignition dial to START again.
NOTE
Before filling with fuel in the event of fuel shortage:
• Stop the car on as flat/level ground aspossible - if the car is tilting there is a riskof air pockets in the fuel supply.

STARTING AND DRIVING

Driving with a trailer
When driving with a trailer, there are a number of points that are important to think about regar-ding the towing bracket, the trailer and how theload is positioned in the trailer.
Payload depends on the car's kerb weight. The total of the weight of the passengers and allaccessories, e.g. towbar, reduces the car's pay-load by a corresponding weight. The car is supplied with the necessary equipment for towing a trailer.
• The car's towing bracket must be of anapproved type.
• Distribute the load on the trailer so that theweight on the towing bracket complies withthe specified maximum towball load. Towballload is calculated as part of the car's payload.
• Increase the tyre pressure to the recom-mended pressure for a full load. For moreinformation on tyre pressure, see the section"Approved tyre pressures".
• The engine is loaded more heavily than usualwhen driving with a trailer.
• Do not tow a heavy trailer when the car isbrand new. Wait until it has been driven atleast 1000 km.
• The brakes are loaded much more than usualon long and steep downhill slopes. Downshiftto a lower gear and adjust your speed. •
Follow the regulations in force for the permit-ted speeds and weights.
• Maintain a low speed when driving with atrailer up long, steep ascents.
• The maximum trailer weights given only applyto altitudes up to 1000 metres above sealevel. At higher altitudes, engine power andthus the car's climbing ability is decreaseddue to the reduced air density, and the maxi-mum trailer weight must therefore bereduced. The weight of the car and trailermust be decreased by 10 % for each addi-tional 1000 m (or part thereof).
• Avoid driving with a trailer on inclines of morethan 12%.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel quality are factors that consider-ably increase the car's fuel consumption.
Trailer connectorAn adapter is required if the car's towing bracket has a 13 pin connector and the trailer has a 7 pinconnector. Use an adapter approved by Volvo.Make sure the cable does not drag on theground.
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
Trailer weightsInformation about Volvo's permitted trailer weights is available in the article "Towingcapacity and towball load".
WARNING
Follow the stated recommendations for trailer weights. Otherwise, the car and trailer may bedifficult to control in the event of suddenmovement and braking.
NOTE
The stated maximum permitted trailer weights are those permitted by Volvo. National vehicleregulations can further limit trailer weightsand speeds. Towbars can be certified forhigher towing weights than the car canactually tow.

WHEELS AND TYRES
484
Tread wear indicators on the tyres Tread wear indicators show the status of the tyre's tread depth.
A tread wear indicator is a narrow elevation across the longitudinal grooves of the tyre's treadpattern. On the side of the tyre are the lettersTWI (Tread Wear Indicator). When the tyre's treaddepth is down to 1.6 mm, the tread will be level inheight with the tread wear indicators. Change tonew tyres as soon as possible. Remember thattyres with little tread depth provide very poor gripin rain and snow.

•Tyres (p. 482)
Checking the tyre pressures Tyres with the correct air pressure increase driv- ing safety, save fuel and extend the service life ofthe tyres.
Tyre pressure decreases over time, this is a natu- ral phenomenon. Tyre pressure also variesdepending on ambient temperature. Inadequatetyre pressure increases fuel consumption, short-ens tyre lifespan and impairs the car's drivingcharacteristics. Driving on tyres with tyre pressurethat is too low could result in the tyres overheat-ing and being damaged. Tyre pressure affectstravelling comfort, road noise and driving charac-teristics.
Recommended tyre pressure
The tyre pressure label on the driver's side door pillar (between frame and rear door) shows which pressures the tyres should have at different loadsand speed conditions.
Improved fuel economy with ECO pressure
For a light load (max. 3 people) and a speed of up to 160 km/h (100 mph), the ECO pressurescan be chosen for optimum fuel economy. How-ever, the lower comfort pressures are recom-mended instead if optimum noise and travellingcomfort are desired.
Checking the air pressure1. Check the tyre pressures monthly. Carry out
the check on cold tyres, which means thatthe tyres should have the same temperatureas the outside temperature. After several fewkilometres of driving, the tyres warm up andthe pressure increases.
2. If necessary, inflate so that the air pressure corresponds with the approved tyre pressurein accordance with the tyre pressure label.
NOTE
• After a tyre has been inflated, always refit the dust cap in order to avoid damage tothe valve from gravel, dirt, etc.
• Only use plastic dust caps. Metal dustcaps can rust and become difficult tounscrew.

Fuel consumption and CO2 emissions
Fuel consumption and CO2 emissions can be affected negatively by several causes.
Examples of reasons for increased fuel consump- tion are as follows:• If the car is equipped with extra equipmentthat affects the car's weight.
• The driver's driving style.
• If the customer chooses wheels other thanthose fitted as standard on the model's basicversion then rolling resistance may increase.
• High speed results in increased wind resis-tance.
• Fuel quality, road and traffic conditions,weather and the condition of the car.
A combination of the above-mentioned examplescan result in significantly increased consumption.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel quality are factors that consider-ably increase the car's fuel consumption.
