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

Cleaning the exterior
The car should be washed as soon as it becomes dirty. This means that the car is easierto clean since the dirt does not attach as firmly.It also reduces the risk of scratches and keepsthe car fresh. Wash the car in a car wash with oilseparator. Use car shampoo.
Handwashing
• Remove bird droppings from the paintwork as soon as possible. Bird droppings containchemicals that affect and discolour paintworkvery quickly. For example, use soft paper orsponge soaked in plenty of water. An author-ised Volvo workshop is recommended for theremoval of any discoloration.
• Hose down the underbody.
• Rinse the entire car until the dissolved dirthas been removed so as to reduce the risk ofscratches from washing. Do not spray directlyonto the locks.
• If necessary, use cold degreasing agent onvery dirty surfaces. Note that in this case, thesurfaces must not be hot from the sun.
• Wash using a sponge, car shampoo andplenty of lukewarm water.
• Clean the wiper blades with a lukewarm soapsolution or car shampoo.
• Dry the car using a clean, soft chamois or awater scraper. If you avoid allowing drops ofwater to dry in strong sunlight, you reduce the risk of water drying stains which mayneed to be polished out.
WARNING
Always have the engine cleaned by a work- shop. There is a risk of fire if the engine is hot.
IMPORTANT
Dirty headlamps have impaired functionality. Clean them regularly, e.g. when refuelling. Do not use any corrosive cleaning agents but use water and a non-scratching spongeinstead.
NOTE
Outside lighting such as headlamps and rear lamps may temporarily have condensation onthe inside of the lens. This is normal, all exte-rior lighting is designed to withstand this.Condensation is normally vented out of thelamp housing when the lamp has beenswitched on for a time.
Automatic car washAn automatic car wash is a simple and quick way of washing the car, but it cannot reach every-where. Washing the car by hand is recommendedto achieve a good result, or to supplement auto-matic car washes with washing by hand.
NOTE
The car must only be washed by hand over the first few months. This is because the paintis more delicate when it is new.
IMPORTANT
Before driving the car into an automatic car wash, deactivate the functions for Automaticbraking when stationary (Auto Hold) andAutomatic application of parking brake. Ifthese functions are not deactivated, the brakesystem will jam when the car is stationary andthe car will not be able to move.
In car washes where the car is towed through with rolling wheels, the following applies:
1. Drive into the automatic car wash.
2. Deactivate the function for automatic braking
when stationary (Auto Hold) using the switch in the tunnel console.
3. Deactivate the function for automatic appli- cation of parking brake via the centre display.
4. Move the gear lever to position N.

knob in the tunnel console to STOP. Hold
the knob in STOP position for at least
4 seconds.
> The car is ready for the automatic car wash.
IMPORTANT
The system will automatically switch to P
mode unless the above step is followed. The wheels are locked in P mode, which they
should not be when putting the car through an automatic car wash.
High-pressure washingWhen using high-pressure washing, use sweep- ing movements and make sure that the nozzledoes not come closer than 30 cm to the surfaceof the car. Do not spray directly onto the locks.
Testing the brakesLightly depress the brake pedal now and thenwhen driving long distances in rain or slush. Theheat from the friction causes the brake linings towarm up and dry. Do the same thing after startingin very damp or cold weather.
WARNING
Always test the brakes after washing the car, including the parking brake, to ensure thatmoisture and corrosion do not attack thebrake linings and reduce braking perform-ance.
Wiper bladesAsphalt, dust and salt residue on wiper blades, as well as insects, ice etc. on the windscreen, impairthe service life of wiper blades. When cleaning, set the wiper blades in service position.
NOTE
Wash the wiper blades and windscreen regu- larly with lukewarm soap solution or carshampoo. Do not use any strong solvents.
Exterior plastic, rubber and trim components
A special cleaning agent available from Volvo dealers is recommended for the cleaning andcare of coloured plastic parts, rubber and trimcomponents, e.g. glossy trim mouldings. Whenusing such a cleaning agent the instructionsmust be followed carefully. The frames around the side windows, the car's roof rails and the door frames at the windows *
are produced in anodised aluminium. This means that they should only be washed using a cleaning agent with a pH value between 3.5 and 11.5.This is in order to avoid discolouration.
Parts that should be washed using a cleaning agent with a pH value between 3.5 and 11.5.
IMPORTANT
Avoid waxing and polishing on plastic and rubber. When using degreasant on plastic and rubber, only rub with light pressure if it is necessary.Use a soft washing sponge. Polishing glossy trim mouldings could wear away or damage the glossy surface layer. Polishing agent that contains abrasive must not be used.
