STARTING AND DRIVING
426
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.
Direction indicators and brake lights on the trailer
If one or more of the trailer's direction indicators or brake light bulbs is broken, the driver display

Weights Max. gross vehicle weight, etc. can be read on a label in the car.
Kerb weight includes the driver, the fuel tank 90% full and all fluids. The weight of passengers and accessories, and towball load (when a trailer is hitched) influencethe load capacity and are not included in the kerbweight. Permitted max. load = Gross vehicle weight - Kerb weight.
NOTE
The documented kerb weight applies to cars in the standard version - i.e. a car withoutextra equipment or accessories. This meansthat for every accessory added the loadingcapacity of the car is reduced correspondinglyby the weight of the accessory. Examples of accessories that reduce load capacity are the different equipment levels(e.g. Kinetic, Momentum, Summum), as wellas other accessories such as towbar, loadcarrier, space box, audio system, auxiliarylamps, GPS, fuel-driven heater, safety grille,carpets, cargo cover, power seats, etc. Weighing the car is a certain way of ascer- taining the kerb weight of your own particularcar.
WARNING
The car's driving characteristics change depending on how heavily it is loaded andhow the load is distributed.
The decal is positioned on the door pillar, and will be visible when the right-hand rear door is opened.
