STARTING AND DRIVING
386

Preconditioning
•If possible, precondition the vehicle with thecharging cable before driving.
•Avoid parking the vehicle so that the passen-ger compartment becomes too hot or cold.Park, if possible, in a climate controlled park-ing garage.
•For short drives after using the precondition-ing function, turn off the climate systemblower if possible.
•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.

Driving
•Choose the Pure drive mode to help mini-mize electric power consumption.
•Maintain a constant speed and an adequatedistance to the vehicle ahead to minimizeuse of the brakes.
•Brake as gently as possible; doing socharges the hybrid battery using the inte-grated regenerative braking function.
•Balance energy requirements using theaccelerator pedal and utilize the gauge onthe instrument panel to see the amount ofpower available from the electric motor. Thishelps avoid starting the gasoline engineunnecessarily. The electric motor is more
energy-efficient than the gasoline engine,especially at lower speeds.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.
•Higher speeds increase energy consumptionand the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
•Avoid carrying unnecessary items (extra load)in the vehicle.
•Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
•Remove snow tires when threat of snow orice has ended.
•Note that roof racks, ski racks, etc, increaseair resistance and also energy consumption.
•Avoid driving with open windows.

Handling and roadholding
•Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
•At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned more
than might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

Using the electric motor in citydriving
A number of factors affect the electric motor'sdriving range.
The driver can affect some of these factors whileothers depend on outside conditions such astemperature, road surface, etc.

Factors that determine the electric
motor's driving range
Factors outside of the driver's control
The following are examples of factors that thedriver cannot control:
•The current traffic situation
•Driving short distances
•Topography
•Ambient temperature and headwinds
•Road conditions/road surface
The following table shows the approximate rela-tionship between ambient temperature and driv-ing range using the electric motor (with reducedclimate system functionality). Warmer tempera-tures increase driving range.
77°F (25°C)105%
68°F (20°C)100%
50°F (10°C)90%
40°F (5 °C)85%
32°F (0°C)80%
23°F (-5°C)75%
14°F (-10°C)70%
Factors in the driver's control
The driver should be aware of the following fac-tors in order to utilize the vehicle's electric motormost efficiently:
•Charge the hybrid battery regularly
•Preconditioning
•The Pure drive mode
•Climate system settings
•Speed and acceleration
•Tires and inflation pressure
The following table shows the approximate rela-tionship between constant speed and drivingrange where driving at a lower constant speedhelps increase the electric motor's driving range.
62 mph (100 km/h)70%
55 mph (90 km/h)80%
50 mph(80 km/h)90%
43 mph (70 km/h)100%
37 mph (60 km/h)110%
30 mph(50 km/h)120%
NOTE
•The figures in the preceding tables per-tain to a new vehicle.
•None of the figures are absolute and areaffected by e.g., driving style, weather,traffic conditions, etc.

Driving with the electric motor
Use the Pure drive mode for the most energy-efficient driving to help maximize driving rangeusing the electric motor only.

sidewall (see the illustration). A tire with e.g., visi-ble cracks or discoloration should be replacedimmediately.

Tire economy
•Maintain correct tire pressure.
•Avoid fast starts, hard braking and tirescreeching.
•Tire wear increases with speed.
•Correct front wheel alignment is very impor-tant.
•Unbalanced wheels impair tire economy anddriving comfort.
•Tires must maintain the same direction ofrotation throughout their lifetime.
•When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
•Hitting curbs or potholes can damage thetires and/or wheels permanently.

Tire rotation
Your vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should onlybe moved from front to rear or vice versa.They should never be rotated left toright/right to left.
•Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
•Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).

Storing wheels and tires
When storing complete wheels (tires mounted onrims), they should be suspended off the floor orplaced on their sides on the floor.
Tires not mounted on rims should be stored ontheir sides or standing upright, but should not besuspended.

CAUTION
Tires should preferably be stored in a cool,dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
•The wheel and tire sizes for your Volvoare specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
•Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.

Tire sidewall designations
The following information can be found on atire's sidewall.
Federal law mandates that tire manufacturersplace standardized information on the sidewall ofall tires (see the illustration).
The vehicle has been certified with certain combi-nations of wheels and tires.
The following information is listed on the tiresidewall:
The tire designation:

NOTE
Please be aware that the following tire desig-nation is an example only and that this par-ticular tire may not be available on your vehi-cle.
1.215: the width of the tire (in millimeters)from sidewall edge to sidewall edge. Thelarger the number, the wider the tire.
2.65: The ratio of the tire's height to its widthin percent.
3.R: Radial tire (the designation RF and the
symbol indicate that the vehicle isequipped with optional self-supporting run
flat tires3.
4.15: The diameter of the wheel rim (ininches).
5.95: The tire's load index. In this example, aload index of 95 equals a maximum load of1521 lbs (690 kg).
6.H: The tire's speed rating, or the maximumspeed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).
NOTE
The tire's load index and speed rating maynot appear on the sidewall because they arenot required by law.
7.M+S or M/S = Mud and Snow, AT = All Ter-rain, AS = All Season
8.U.S. DOT Tire Identification Number(TIN): This begins with the letters "DOT" andindicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9.Tire Ply Composition and MaterialUsed: Indicates the number of plies indi-cates or the number of layers of rubber-coated fabric in the tire tread and sidewall.Tire manufacturers also must indicate the plymaterials in the tire and the sidewall, whichinclude steel, nylon, polyester, and others.
3Self-supporting run flat tires may not be available on all models

10.Maximum Load: Indicates the maximumload in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11.Treadwear, Traction, and Temperaturegrades.
12.Maximum permissible inflationpressure: the greatest amount of air pres-sure that should ever be put in the tire. Thislimit is set by the tire manufacturer.

Speed Symbol
A tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed.
Winter tires, with our without studs, are excep-tions and may use a lower SS. When winter tiresare installed, the vehicle may not be driven fasterthan the tires' SS.
The vehicle's speed should always be determinedby the posted speed limit and traffic and roadconditions, not the tire's SS.
The following table indicates the maximum per-missible speed for each SS.
Speed Symbol
M81 mph (130 km/h)
Q100 mph (160 km/h)
T118 mph (190 km/h)
H130 mph (210 km/h)
V149 mph (240 km/h)
W168 mph (270 km/h)
Y186 mph (300 km/h)

Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,notes or warnings such as standard load, radialtubeless, etc.
•Tire information placard: A placard show-ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
•Tire Identification Number (TIN): A numberon the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacturer.
•Inflation pressure: A measure of theamount of air in a tire.
•Standard load: A class of P-metric or Metrictires designed to carry a maximum load at35 psi [37 psi (2.5 bar) for Metric tires].Increasing the inflation pressure beyond thispressure will not increase the tires load car-rying capability.
•Extra load: A class of P-metric or Metrictires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
•kPa: Kilopascal, a metric unit of air pressure.
•PSI: Pounds per square inch, a standard unitof air pressure.
•B-pillar: The structural member at the sideof the vehicle behind the front door.
•Bead area of the tire: Area of the tire nextto the rim.
•Sidewall of the tire: Area between the beadarea and the tread.
•Tread area of the tire: Area of the perime-ter of the tire that contacts the road whenmounted on the vehicle.
•Rim: The metal support (wheel) for a tire or atire and tube assembly upon which the tirebeads are seated.
•Maximum load rating: a figure indicatingthe maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
•Maximum permissible inflation pressure:the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.
•Recommended tire inflation pressure:inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
•Cold tires: The tires are considered to becold when they have the same temperatureas the surrounding (ambient) air. This tem-
perature is normally reached after the vehiclehas been parked for at least 3 hours.

Tire direction of rotation
Incorrectly mounted tires impair the car's brakingproperties and ability to force aside rain, snowand slush.
The arrows shows the direction of rotation of the tire
•The tires with the most tread should alwaysbe on the rear axle (to help reduce the risk ofskidding).
•When switching between summer and wintertires, mark the tires to indicate where theywere mounted on the car, e.g., LF = left front,RR = right rear
•Tires with tread designed to roll in only onedirection are marked with an arrow on thesidewall.
•Contact a trained and qualified Volvo servicetechnician if you are unsure about the treaddepth.

Related information
•Tires (p. 478)Tread wear indicator
The tires have wear indicator strips runningacross or parallel to the tread.
The letters TWI are printed on the side of the tire.When approximately 1/16" (1.6 mm) is left onthe tread, these strips become visible and indi-cate that the tire should be replaced. Tires withless than 1/16" (1.6 mm) tread offer very poortraction.
When replacing worn tires, it is recommendedthat the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of thesame make (manufacturer) will help preventalteration of the driving characteristics of thevehicle.
