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.

WHEELS AND TYRES
482
TyresAmongst other things, the function of the tyres is to carry load, provide grip on the road surface,dampen vibration and protect the wheel fromwear.
The tyres greatly affect the car's driving characte- ristics. The type of tyre, dimensions, tyre pressureand speed rating are important for how the carperforms.
Recommended tyresOn delivery, the car is equipped with Volvo origi- nal tyres that have the VOL 1
marking on the side
of the tyres. These tyres are carefully adapted to the car. In the event of changing tyres, it is there-fore important that the new tyres also have thismarking in order for the car's driving characteris-tics, comfort and fuel consumption to be main-tained.
New tyres
Tyres are perishable. After a few years they begin to harden at the same time as the frictioncapacity/characteristics gradually deteriorate. Forthis reason, aim to get as fresh tyres as possiblewhen you replace them. This is especially impor-tant with regard to winter tyres. The last four dig-its in the sequence mean the week and year ofmanufacture. This is the tyre's DOT marking(Department of Transportation), and this is statedwith four digits, for example 0715. The tyre in thefigure was manufactured in week 07 of 2015.
Tyre ageAll tyres older than 6 years old should bechecked by an expert even if they seem undam-aged. Tyres age and decompose, even if they arehardly ever or never used. The function cantherefore be affected. This applies to all tyres that are stored for future use. Examples of externalsigns which indicate that the tyre is unsuitable foruse are cracks or discoloration.
Wear and maintenanceCorrect tyre pressure results in more even wear.Driving style, tyre pressure, climate and road con-dition affect how quickly the tyres age and wear. To avoid differences in tread depth and to pre- vent wear patterns forming on the tyres, the frontand rear wheels can be switched with each other.A suitable distance for the first change is approx.5000 km and then at 10000 km intervals. Volvo recommends the an authorised Volvo work- shop is contacted for checking if you are uncer-tain about tread depth. If significant differences inwear (> 1 mm difference in tread depth) betweentyres have already occurred, then the least worntyres must always be fitted on the rear. Under-steer is normally easier to correct than oversteer,and leads to the car continuing forwards in astraight line rather than having the rear end skid-ding to one side, resulting in possible completeloss of control over the car. This is why it isimportant for the rear wheels never to lose gripbefore the front wheels.
WARNING
A damaged tyre may lead to loss of control over the car.

There may be deviations for certain tyre dimensions.

IMPORTANT
Risk of overheating. The compressor must not run for more than 10 minutes.
5. Inflate the tyre to the pressure specified on
the tyre pressure label on the driver side door pillar. (Release air using the pressure reduc-ing valve if the tyre pressure is too high.)
6. Switch off the compressor. Detach the airhose and cable.
7. Refit the dust cap.

When changing wheels
The car's wheels can be changed, e.g. to winter wheels or a spare wheel.
Follow the relevant instructions for removing and fitting wheels.
When changing to another tyre
dimension
Check that the tyre dimension is approved foruse on the car. Contact an authorised Volvo workshop for updat- ing the software at each change of tyre dimen-sion. A software download may be necessaryboth when changing to larger and smaller dimen-sions, and also when switching between summerand winter wheels.

Removing a wheel
Instructions for removing a wheel when chang- ing wheels.
1. Set up the warning triangle and activate the hazard warning lights if a tyre is being changed in a trafficked location.
2. Apply the parking brake and engage gear position P, or engage first gear if the car has
a manual gearbox. Applies to cars with
Leveling Control* : If
the car is equipped with air suspension, this must be disabled before the car is raised with a jack *.

Winter wheels
Winter wheels are adapted for winter road con- ditions.
Volvo recommends winter tyres with particular dimensions. Tyre dimensions are dependent onengine variant. When driving on winter tyres, thecorrect type of tyres must be fitted to all fourwheels.
NOTE
Contact a Volvo dealer for advice about which wheel rim and type of tyre are most suitable.
Tips for changing to winter tyresWhen summer and winter wheels are changed, mark which side of the car they were mounted on, for example L for left and R for right.
Studded tyresStudded winter tyres should be run in gently for 500-1000 km so the studs settle properly intothe tyres. This gives the tyre, and especially thestuds, a longer service life.
NOTE
The legal provisions for the use of studded tyres vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tyresthan summer conditions. Volvo therefore recom-mends not to drive on winter tyres that have atread depth of less than 4 mm.
Snow chainsVolvo recommends that snow chains are notused on wheel dimensions greater than18 inches. Mounting instructions are supplied with Volvo original snow chains. Snow chains may only be used on the front wheels (also applies to all-wheel drive cars).Never drive faster than 50 km/h (30 mph) withsnow chains. Avoid driving on bare ground as thiswears out both the snow chains and tyres.
WARNING
Use Volvo genuine snow chains or equivalent chains designed for the car model, and tyre and rim dimensions. Only single-sided snow
chains are permitted. In the event of uncertainty about the show chain, Volvo recommends that an authorisedVolvo workshop should be contacted. Thewrong snow chains may cause serious dam-age to the car and lead to an accident.

Jack*
Use the jack to raise the car when changing a wheel.
Only use the original jack when fitting a spare wheel or when changing between summer andwinter wheels. The jack's thread must always bewell greased.
IMPORTANT
The tools and jack * must be stored in the
intended location in the car's cargo area when not in use.
The jack needs to be cranked together to the correct position in order to have space.
NOTE
The normal car jack is only designed for occa- sional, short-term use, such as when chang-ing a wheel after a puncture, changing to win-ter/summer wheels, etc. Only the jack for thespecific car model may be used to raise thecar. If the car is to be jacked up more often, orfor a longer time than is required just tochange a wheel, use of a garage jack is rec-ommended. In this instance, follow theinstructions for use that come with the equip-ment.
Applies to cars with level control *
If the car is equipped with air suspension then this must be deactivated before the car is raisedwith the jack. Switch off the function via the centre display:1.

40 Ratio between tyre wall height and tyre width (%)
R Radial ply
19 Rim diameter in inches
100 Codes for the maximum permitted tyre load, tyre load index (LI)
W Speed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h (168 mph).)
Load indexEach tyre has a certain capacity to carry a load, a load index (LI). The car's weight determines theload capacity required of the tyres. The lowestpermitted load index is specified in a load indextable.
Speed ratingEach tyre can withstand a certain maximumspeed. Tyre speed rating, SS (Speed Symbol),must at least correspond with the car's topspeed. The table below shows the maximum per-mitted speed for each speed rating (SS). Theonly exception to these regulations is winter tyres3
, where a lower speed rating may be used.
If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (forexample, class Q can be driven at a maximum of160 km/h (100 mph).) The top speed at whichthe car can be driven depends on road condi-tions, not the speed rating of the tyres.
NOTE
The maximum permitted speed is specified in the table.
Q 160 km/h (100 mph) (used only on win- ter tyres)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph)
