Driving in water Driving in water means that the car is driven through deep water on a water-covered road-way. Driving in water must be carried out withgreat caution.
The car can be driven through water at a maxi- mum depth of 25 cm at a maximum speed ofwalking pace. Extra caution should be exercisedwhen passing through flowing water. During driving in water, maintain a low speed and do not stop the car. When the water has beenpassed, depress the brake pedal lightly andcheck that full brake function is achieved. Waterand mud for example can make the brake liningswet resulting in delayed brake function.
• If necessary, clean the contacts for the elec-tric heater and trailer coupling after driving inwater and mud.
• Do not let the car stand with water over thesills for any long period of time - this couldcause electrical malfunctions.

Overloading the starter battery
The electrical functions in the car load the starter battery to varying degrees. Avoid using the igni-tion position II when the car is switched off.
Instead, use ignition position I - which uses less
power.
Also, be aware of different accessories that load the electrical system. Do not use functions whichuse a lot of power when the car is switched off.Examples of such functions are:
• ventilation fan
• headlamps
• windscreen wiper
• audio system (high volume).
If the starter battery voltage is low, the message
12 V Battery Low charge, will soon enter
power save mode is shown in the driver display.
The energy-saving function then shuts down cer- tain functions or reduces certain functions suchas the ventilation fan and/or audio system.
–In which case, charge the starter battery by starting the car and then running it for atleast 15 minutes - starter battery charging ismore effective during driving than runningthe engine at idling speed while stationary.

Preparations for a long trip
Before a driving holiday or some other type of long journey, it is important to check the car'sfunctions and equipment particularly carefully.
Check that:
• the engine is working normally and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• all bulbs are working
• the tyres have sufficient tread depth andpressure
• a warning triangle and high-visibility vest arelocated in the car - legally required in certaincountries
• the wiper blades are in good condition.

Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.

IMPORTANT
Mixtures of various fuel types or use of fuels which are not recommended will invalidateVolvo's guarantees and any supplementaryservice agreements; this is applicable to allengines.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel grade are factors that couldaffect the car's performance.

Petrol
Petrol is a type of engine fuel that is intended for cars with a petrol engine.
Only use petrol from well-known producers. Never use fuel of dubious quality. The petrol mustfulfil the EN 228 standard.
IMPORTANT
• Fuel that contains up to 10 percent by volume ethanol is permitted.
• EN 228 E10 petrol (max10 percent by volume ethanol) isapproved for use.
• Ethanol higher than E10 (max.10 percent by volume ethanol) is not per-mitted, e.g. E85 is not permitted.
Octane rating
•95 RON can be used for normal driving.
• 98 RON is recommended for optimum per- formance and minimum fuel consumption.
When driving in temperatures above +38 °C, fuelwith the highest possible octane rating is recom-mended for optimum performance and fuel econ-omy.
IMPORTANT
• Use only unleaded petrol to avoid damag- ing the catalytic converter.
• Fuel containing metallic additives mustnot be used.
• Do not use any additives which have notbeen recommended by Volvo.

Economical driving
Drive economically and eco-consciously by driv- ing smoothly, thinking ahead, and adjusting yourdriving style and speed to the prevailing condi-tions.
• For lower fuel consumption, activate ECO drive mode.
• Use the Eco Coast 17
freewheel function -
engine braking will cease and the car'skinetic energy can be used to freewheel forlonger distances.
• Drive in the highest gear 18
possible, adapted
to the current traffic situation and road -lower engine speeds result in lower fuel con-sumption. Use the gear shift indicator.
• Drive at a steady speed and keep a good dis-tance to other vehicles and objects to mini-mise braking.
• High speed results in increased fuel con-sumption - the wind resistance increaseswith speed.
• Do not run the engine to operating tempera-ture at idling speed, but rather drive with anormal load right after starting - a coldengine consumes more fuel than a warmone. •
Drive with the correct air pressure in thetyres and check this regularly - select ECOtyre pressure for best results.
• Choice of tyres can affect fuel consumption -seek advice on suitable tyres from a dealer.
• Remove unnecessary items from the car -the greater the load the higher the consump-tion.
• Use engine braking to slow down, when itcan take place without risk to other roadusers.
• A roof load and space box increase windresistance, leading to higher consumption -remove the load carriers when not in use.
• Avoid driving with open windows.
WARNING
Never switch off the engine while moving, such as downhill, this deactivates importantsystems such as the power steering andbrake servo.

Towing bracket
*
The car can be equipped with a towing bracket that makes it possible to tow e.g. a trailer afterthe car.
There may be different towing bracket variants available for the car; contact a Volvo dealer formore information. For information on towing capacity and towball load, see the section "Towing capacity and tow-ball load".
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.
IMPORTANT
The towball needs regular cleaning and lubri- cation with grease in order to prevent wear.
17 See the section "Drive mode ECO".
18 Applies to driving with manual gear changing.

WARNING
Do not press the extend/retract button if a trailer is attached to the towing bracket.
NOTE
The towbar must finish the extension proce- dure before it can then be moved to lockedposition. This procedure may take severalseconds. If the towbar is not fixed in lockedposition, wait a few seconds and try again.
3. Move the towbar to its end position, where it is secured and locked in place - the indicator lamp illuminates with a constant orangeglow.
> The towbar is ready for use.
WARNING
Take care to secure the trailer's safety cable in the intended bracket.
NOTE
Power save mode activates after a while and the indicator lamp goes out. The system isreactivated by closing and opening the tail-gate. This applies when retracting or extend-ing the towing bracket. If the car detects a connected trailer electri- cally, the indicator lamp stops illuminatingwith a constant glow.
Retracting the towing hitch
IMPORTANT
Make sure that there is no plug or adapter in the electrical socket when retracting the tow-ing bracket.
1. Open the tailgate. Press and release the but- ton on the right-hand side at the rear of the cargo area - retraction might not start if thebutton is pressed for too long.

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.
