Supplementary information
Average fuel consumptionFuel consumption since the last time this function was reset.
Average speedThe vehicle's average speed since the lasttime this function was reset.
Current fuel consumptionCurrent fuel consumption is calculatedapproximately once a second. When the vehi-cle is moving at low speed, fuel consumptionis displayed per unit of time. At higherspeeds, it is displayed in terms of distance. Miles or kilometers can be displayed, see theheading "Changing units" on page 222
Distance to emptyThis function shows the approximate dis-tance that can be driven on the fuel remaining in the tank. When
Distance to empty shows
"----", there is very little useable fuel remain- ing in that tank; refuel as soon as possible.The calculation is based on average fuel con-sumption during the last 20 miles (30 km) ofdriving and the amount of fuel remaining inthe tank (the accuracy of this figure may varyif your driving style changes). An economicaldriving style will generally increase this dis-tance. See page276 for information about driving economically.
Digital speed display*Speed is expressed in the unit not used bythe instrument panel's speedometer e.g., ifthe normal speedometer is in mph, the tripcomputer will display in the speed in km/hand vice versa.

General information
Economical driving conserves natural
resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions. Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.
• Using the engine's optional Eco function 1
can help improve fuel economy. Seepage 128 for additional information.
• Do not exceed posted speed limits. •
Avoid carrying unnecessary items (extraload) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended.
• Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive more economically.
Other factors that decrease gas mileage are: • Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and oth- ers are checked at the standard maintenanceintervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous exhaust gases entering the passengercompartment. If the trunk must be keptopen for any reason, proceed as follows:
• Close the windows
• Set the ventilation system control to air flow to floor, windshield and side win- dows and the blower control to itshighest setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a tendency to understeer, which means thatthe steering wheel has to be turned morethan 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 trunk, the less the tendency to under-steer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom-mended pressure according to the vehicle

Introduction
Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to roadhazard damage and, depending on drivingconditions, may achieve a tread life of lessthan 20,000 miles (30,000 km). Even if thisvehicle is equipped with Volvo’s advancedAWD or DSTC system, these tires are notdesigned for winter driving, and should bereplaced with winter tires when weatherconditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of road holding on slippery surfacesthan tires without the "all-season" rating.However, for optimum road holding on icy orsnow-covered roads, we recommend suitablewinter tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the car's roadholding andhandling characteristics.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire rotationYour vehicle has no required tire rotation. Tire wear is affected by a number of factors suchas tire inflation, ambient temperature, drivingstyle, etc.
NOTE
•
If the tires are rotated, they should only be moved from front to rear orvice versa. They should never be rota-ted left to right/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000miles (5,000 km) and thereafter at6,000-mile (10,000-km) intervals.Some customers find that tire rotationmay help to get extra mileage from tirelife.
• Tire rotation should only be performedif front/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre- quent high loading conditions or Ultra Violet(U.V.) exposure can accelerate the aging
