Economical driving
A more economical driving style can help lower fuel consumption.
Before driving
If possible, precondition the vehicle before driving.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe start battery.
Avoid using idling to warm up the vehiclebefore driving.
The type of tires and inflation pressureused could affect energy consumption –consult an authorized Volvo retailer foradvice on suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
While driving

Activate Eco drive mode.
Use gear selector position
D as often as
possible.
When using manual gear shifting, drive using the highest possible gear. Use the gear indicator 19
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. Use engine braking if possi-ble.
Higher speeds increase energy consump-tion because air resistance increases withspeed.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Avoid driving with the windows open.
Do not use the accelerator pedal to keepthe vehicle stationary on an uphill gradi-ent. Instead, activate the auto-hold brakefunction at a standstill.
Use trip data to see current fuel consump-tion.
WARNING
Never turn off the engine while the vehicle is moving, e.g. when driving downhill. Thisdeactivates certain important systemssuch as power steering and brakes.

Tread wear indicatorThe tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's longitudinaltread grooves. The letters TWI (Tread WearIndicator) are visible on the side of the tire.When approximately 1.6 mm (1/16 inch) is lefton the tread, the tread will be at the sameheight as the tread wear indicator. Replace thetire as soon as possible. Tires with low treadoffer very poor traction in rain or snow.

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place standardized information on the sidewallof all tires (see the illustration). The vehicle has been certified with certain combinations of wheels and tires. The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: The width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to bedriven for extended periods of time, carry-ing a permissible load for the vehicle, andwith correct inflation pressure. For exam-ple, H indicates a speed rating of210 km/h (130 mph).
3 Self-supporting run flat tires may not be available on all models.

NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare not required by law.
7.M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT"
and indicates that the tire meets all federalstandards. The next two numbers are thefactory code where the tire was manufac-tured, the next two are the tire size codeand the last four numbers represent theweek and year the tire was made. Forexample, 0717 means that the tire wasmanufactured during week 7 of 2017. Thenumbers in between are marketing codesused at the manufacturer's discretion. Thisinformation helps a tire manufactureridentify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates orthe number of layers of rubber-coated fab-ric in the tire tread and sidewall. Tire man-ufacturers also must indicate the plymaterials in the tire and the sidewall,which include steel, nylon, polyester, andothers.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can be carried by the tire. Refer to the vehicle'stire information placard located on the B-Pillar for the correct tire pressure for yourvehicle.
11. Treadwear, Traction, and Temperaturegrades .
12. Maximum permissible inflationpressure: The greatest amount of air
pressure that should ever be put in thetire. This limit is set by the tire manufac-turer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certi-fied and should be at least equivalent to thevehicle's top speed. Winter tires, with or without studs, are excep- tions and may use a lower SS. When wintertires are installed, the vehicle may not bedriven faster than the tires' SS. The vehicle's speed should always be deter- mined by the posted speed limit and trafficand road conditions, not the tire's SS. The following table indicates the maximum permissible speed for each SS.
M 130 km/h (81 mph)
Q 160 km/h (100 mph)
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)
WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unap-proved wheel/tire size combinationscan negatively affect your vehicle's sta-bility and handling.
Any damage caused by installation ofunapproved wheel/tire size combina-tions will not be covered by your newvehicle warranty. Volvo assumes noresponsibility for death, injury, orexpenses that may result from suchinstallations.

Checking tire pressure
Correct inflation pressure helps improve driv- ing stability, save fuel and increase the serv-ice life of the tires.
Tire pressure decreases over time, which is normal. Tire pressure also varies depending onthe ambient temperature. Driving on under-inflated tires could cause the vehicle to over-heat and lead to damage. Tire pressure affectstraveling comfort, road noise and driving cha-racteristics. Check the pressure in the tires every month. Use the recommended inflation pressure forcold tires to help maintain good tire perform-ance. Under-inflated or over-inflated tirescould cause uneven tread wear. Use an air pressure gauge and check the infla- tion pressure on all the tires, including the spare tire 4
, at least once a month and before
long trips. Volvo recommends buying a relia- ble air pressure gauge, as the automaticgauges provided at service stations may beinaccurate.
WARNING
Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation,or "blow-out," with unexpected loss ofvehicle control and increased risk ofinjury.
Under-inflated tires reduce the loadcarrying capacity of your vehicle.
Cold tiresInflation pressure should be checked when thetires are cold. The tires are considered to becold when they have the same temperature asthe surrounding (ambient) air. This tempera-ture is normally reached after the vehicle hasbeen parked for at least 3 hours. After driving for approximately 1.6 km (1 mile), the tires are considered to be warm. If youneed to drive longer than that to inflate thetires, check and record the inflation pressureof the tires first and inflate accordingly whenyou arrive at the pump. When the ambient temperature changes, so does the inflation pressure. A 10-degree tem-perature drop causes a corresponding drop ininflation pressure of 1 psi (7 kPa). Check theinflation pressure of the tires regularly andadjust to the correct pressure, which can be found on the vehicle's tire information decal orcertification label. If you check inflation pressure when the tires are warm, you should never release air. Thetires become warm after driving and it is nor-mal for warm tires to have an inflation pres-sure above the recommended pressure forcold tires. A warm tire with an inflation pres-sure equal to or under the recommended pres-sure for cold tires could be significantly under-inflated.Related information

Adjusting tire pressureTire pressure decreases over time, which is normal. The tire pressure must therefore beadjusted to maintain the recommended tirepressure.
Use the recommended inflation pressure for cold tires to help maintain good tire perform-ance and even wear.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to becold when they have reached the sametemperature as the ambient temperature(about 3 hours after the vehicle was lastdriven). After driving for a few kilometers,the tires will warm up and the pressure willincrease.
1. Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
2. Inflate the tire to the correct inflation pres- sure; see the tire pressure placard on thedriver's side B pillar for recommendedpressures for factory-mounted tires. 3. Screw the valve cap back on.
NOTE

After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tire to make sure there
are no nails or other embedded objects that could puncture the tire and cause airleakage.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irreg-ularities.
6. Repeat this procedure for each tire, includ- ing the spare tire 5
.
NOTE
If you have overfilled the tire, release air by pushing on the metal stem in the center ofthe valve. Then recheck the pressure withyour tire gauge. Some spare tires require higher inflation pressure than the other tires. Consult thetire inflation pressure table or the inflationpressure decal.

Tire pressure monitoring system
*
The tire inflation pressure monitoring system 6
provides an indicator symbol in the instru- ment panel if pressure is too low in one ormore tires.
This symbol illuminates to indicate low inflation pres-sure. Check the inflation pressure in the
Car Statusapp in the center display. If there is a system malfunc-
tion, the inflation pressure warning symbol will flash for approximately one minute and thenglow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determineif the tires are properly inflated. If inflationpressure in a tire is too low, its diameter (andconsequently its rotational speed) changes. Bycomparing the tires with each other, the sys-tem can determine if the pressure in one ormore tires is too low.

General information about the tire pressure monitoring system
In the following description, the tire monitor- ing system is generally referred to as TPMS. Each tire, including the spare (if provided)7
should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size thanthe size indicated on the vehicle placard or tireinflation pressure label, you should determinethe proper tire inflation pressure for thosetires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illumi-nates, you should stop and check your tires assoon as possible, and inflate them to theproper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tirefailure. Under-inflation also reduces fuel effi-ciency and tire tread life, and may affect thevehicle's handling and stopping ability. Please note that the TPMS is not a substitute forproper tire maintenance, and it is the driver'sresponsibility to maintain correct tire pressure,even if under-inflation has not reached thelevel to trigger illumination of the TPMS lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the systemdetects a malfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequence willcontinue upon subsequent vehicle start-ups aslong as the malfunction exists. When the mal-function indicator is illuminated, the systemmay not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.
To keep in mind

Always save the new inflation pressure inthe system after changing a tire or adjust-ing the inflation pressure.
If you switch to a tire of another size thanthe factory-mounted tires, the systemmust be reset by storing a new inflationpressure for these tires to avoid falsewarnings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system willnot work correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tirepressure monitoring system.
WARNING

Incorrect inflation pressure could lead to tire failure, which could cause thedriver to lose control of the vehicle.
The system cannot predict sudden tiredamage.

Saving new reference values for tire inflation pressure monitoring *
In order for the tire inflation pressure moni- toring system 9
to function correctly, inflation
pressure reference values must be saved cor- rectly. To help ensure that the system cancorrectly alert the driver of low inflation pres-sure, this must be done each time the tiresare changed or the inflation pressure isadjusted.
For example, when driving with a heavy load or at high speeds (over 160 km/h (100 mph)),tire pressure should be adjusted to the Volvo-recommended tire pressure values. The sys-tem should then be reset by saving the newinflation pressure. To store the new inflation pressure as a refer- ence value in the system:
1. Switch off the ignition.
2. Inflate the tire to the correct inflation pres- sure; see the tire pressure placard on the driver's side B pillar for recommendedpressures for factory-mounted tires.
3. Start the vehicle. 4. Open the
Car Status app in App view.
5. Tap
TPMS.
NOTE
The vehicle must be stationary for theStore Pressure button to be selectable.
6.Tap Store Pressure.
7. Tap
OK to confirm that the tire pressure in
all four tires has been checked and adjusted.
8. Drive the vehicle until the new inflation pressure has been saved. The new infla-tion pressure is stored when the vehicle isdriven at speeds over 35 km/h (22 mph).
> When enough data has been collectedfor the system to detect low inflation pressure, the animation showing theprogress of the storing procedure willdisappear from the center display. Thesystem will not provide any further con-firmation that the new inflation pres-sure has been stored.
