Drive-E ‒ purer driving pleasure
Volvo is committed to the well-being of its customers. As a natural part of this commit-ment, we care about the environment inwhich we all live. Concern for the environ-ment means an everyday involvement inreducing our environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider theoverall environmental impact of a productthroughout its complete life cycle. In this con-text, design, production, product use, andrecycling are all important considerations. Inproduction, Volvo has partly or completelyphased out several chemicals including CFCs,lead chromates, asbestos, and cadmium; andreduced the number of chemicals used in ourplants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic converterwith a Lambda sond, now called the heatedoxygen sensor, in 1976. The current version ofthis highly efficient system reduces emissionsof harmful substances (CO, HC, NOx) from theexhaust pipe by approximately 95 - 99% andthe search to eliminate the remaining emis-sions continues. Volvo is the only automobilemanufacturer to offer CFC-free retrofit kits forthe air conditioning system of all models as farback as the 1975 model 240. Advanced elec-tronic engine controls and cleaner fuels arebringing us closer to our goal. In addition to continuous environmental refinement of con-ventional gasoline-powered internal combus-tion engines, Volvo is actively looking atadvanced technology alternative-fuel vehicles. When you drive a Volvo, you become our part- ner in the work to lessen the vehicle's impacton the environment. To reduce your vehicle'senvironmental impact, you can:
Maintain proper air pressure in your tires.Tests have shown decreased fuel econ-omy with improperly inflated tires.
Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
Drive at a constant speed whenever possi-ble.
See a trained and qualified Volvo servicetechnician as soon as possible for inspec-tion if the check engine (malfunction indi-cator) light illuminates, or stays on afterthe vehicle has started.
Properly dispose of any vehicle-relatedwaste such as used motor oil, used batter-ies, brake pads, etc.
When cleaning your vehicle, please usegenuine Volvo car care products. All Volvocar care products are formulated to beenvironmentally friendly.
Twin Engine vehicles
If possible, precondition the vehicle withthe charging cable before driving.
If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reducesthe hybrid battery's charge level.
Choose the
Pure drive mode to help mini-
mize electric power consumption.
In hilly terrain, put the gear selector in mode
B to utilize the electric motor's
braking function when the acceleratorpedal is released. This helps charge thehybrid battery.

Airbags
The vehicle is equipped with airbags and inflatable curtains for the driver and passen-gers.
WARNING
If the airbag warning light stays on after the engine has started or if it illu-minates while you are driving, have thevehicle inspected by a trained andqualified Volvo service technician assoon as possible.
Never attempt to alter or repair any ofthe vehicle's safety systems yourself.Incorrectly performed repairs to anysystem could impair function and leadto serious injury. All work on these sys-tems should be performed by a trainedand qualified Volvo service technician.
WARNING
If your vehicle has become water-damaged in any way (e.g., soaked floor mats/stand-ing water on the floor of the vehicle), donot attempt to start the engine. This maycause airbag deployment, which couldresult in serious injury. Volvo recommendstowing the vehicle directly to an authorizedVolvo workshop. Before attempting to tow the vehicle:
1. Switch off the ignition for at least 10
minutes and disconnect the battery.
2. Follow the instructions for manually overriding the shiftlock system.
Deployed airbags
WARNING
If any of the airbags have deployed:
Do not attempt to drive the vehicle. Have it towed to an authorized work-shop.
If necessary, seek medical attention.

Driver/passenger-side airbags 2
As a supplement to the seat belts, the vehicle is equipped with driver and passenger sidefront airbags.
Driver/passenger side front airbags.
In a frontal collision, the airbags help protect the driver's and passenger's head, neck, faceand chest and the driver's knees and legs. A collision of a sufficiently violent force will trigger the sensors and one or more airbagswill inflate. The airbag helps cushion the initialimpact of the collision for the passenger. Theairbag deflates when compressed by the colli-sion. A small amount of powder will also bereleased from the airbag. This may appear tobe smoke and is normal. The entire process, from inflation to deflation of the airbag, occurs within tenths of a second.

SAFETY

NOTE
The sensors react differently depending on the circumstances of the accident andwhether or not the seat belt is used. Thisapplies to all belt positions. There may therefore be accident situations in which only one (or none) of the airbagsare deployed. The sensors monitor theimpact of the collision and react accord-ingly to deploy one, several or no airbags.
WARNING
The seat belt and the airbag work together. If the seat belt is not used or is used incor-rectly, the airbag may not provide theintended protection in a collision. To help prevent injury in the event the air- bag is deployed, passengers should sit asupright as possible, with their feet on thefloor and their backs against the seat back-rest.
WARNING
Volvo recommends contacting an author- ized Volvo workshop for repairs. Incorrectlyperformed repairs to the airbag systemcould impair function and lead to seriousinjury.
The front airbag systemThe front airbag system includes gas genera- tors surrounded by the airbags, and decelera-tion sensors that activate the gas generators,causing the airbags to be inflated with nitro-gen gas. As the movement of the seats' occupants compresses the airbags, some of the gas isexpelled at a controlled rate to provide bettercushioning. The belt tensioners minimize slackin the seat belts and are activated for occu-pants wearing their seat belts. The entire proc-ess, from inflation to deflation of the airbag,occurs within tenths of a second. The location of the front airbags is indicated by SRS AIRBAG embossed on the steering
wheel pad and above the glove compartment,and by decals on both sun visors and on thefront and far right side of the dash. The driver's side front airbag is folded and
located in the steering wheel hub.The knee airbag is folded on the underside of
the dashboard on the driver's side. The text AIRBAG is embossed on the panel.
The passenger's side front airbag is folded
behind a panel located above the glove com-partment.WARNING
The airbags in the vehicle are designed to be a SUPPLEMENT to-not areplacement for-the three-point seatbelts. For maximum protection, wearseat belts at all times. Be aware that nosystem can prevent all possible injuriesthat may occur in an accident.
Never drive with your hands on thesteering wheel pad/airbag housing.
The front airbags are designed to helpprevent serious injury. Deploymentoccurs very quickly and with considera-ble force. During normal deploymentand depending on variables such asseating position, one may experienceabrasions, bruises, swellings, or otherinjuries as a result of deployment ofone or both of the airbags.
When installing any accessory equip-ment, make sure that the front airbagsystem is not damaged. Any interfer-ence in the system could cause mal-function.

NOTE
Dirt, ice and snow covering the sensors reduce their function and can make meas-urement impossible.
Driver responsibilityThe driver should keep in mind that the func- tion is a parking aid ‒ not an infallible fully
automatic system. The driver must always beprepared to take control and cancel a parkingsequence if necessary. There are a number of things to keep in mind when parking, including:
The driver is always responsible for deter-mining if the space suggested by the func- tion is suitable for parking.
Do not use the function when using snow chains or a temporary spare tire.
Do not use the function if there are anyobjects protruding from the vehicle.
Heavy rain or snowfall may inhibit PAP'sability to accurately measure a parkingspace.
While searching and measuring the park-ing space, the function may be unable todetect objects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect suffi-cient space for maneuvering the vehicle.
Use approved tires 101
inflated to the cor-
rect tire pressure because this affects thefunction's ability to provide parking assis-tance.
The function is based on the way the vehi-cles are parked behind and in front of yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rimscould be damaged by the curb during theparking procedure.
Perpendicular parking spaces may not bedetected or may be suggested unneces-sarily if a parked vehicle is sticking outmore than other parked vehicles.
The function is intended to provide park-ing assistance on straight streets, not sec-tions of street with sharp curves or bends.Always make sure that your vehicle is par-allel to relevant parking spaces when thefunction is measuring the parking space.

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 terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional mark- ings, notes or warnings such as standard load,radial tubeless, etc.
Tire information placard
: A placard
showing the OE (Original Equipment) tiresizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
Tire Identification Number (TIN)
: A num-
ber on the sidewall of each tire providinginformation about the tire brand and man-ufacturing plant, tire size and date of man-ufacture.
Inflation pressure
: A measure of the
amount of air in a tire.
Standard load
: A class of P-metric or
Metric tires designed to carry a maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
Extra load
: A class of P-metric or Metric
tires 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 pres-
sure.
PSI
: Pounds per square inch, a standard
unit of air pressure.
B-pillar
: The structural member at the
side of the vehicle behind the front door.
Bead area of the tire
: Area of the tire next
to the rim.
Sidewall of the tire
: Area between the
bead area 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 a tire and tube assembly upon whichthe tire beads are seated.
Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
Maximum permissible inflationpressure
: the greatest amount of air pres-
sure that should ever be put in the tire.This limit is set by 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 infla-

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 pres-
sure that should ever be put in the tire.This limit is set by the tire manufacturer.
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)
