goal. In addition to continuous environmentalrefinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles.
When you drive a Volvo, you become our partnerin the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
Drive at a constant speed whenever possible.
See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Twin Engine vehicles
If possible, precondition the vehicle with thecharging cable before driving.
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.
Choose the Pure drive mode to help mini-mize electric power consumption.
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.

IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regardingvehicle safety. IntelliSafe consists of a number ofsystems, both standard and optional, that aredesigned to help make driving safer, preventaccidents and protect passengers and otherroad users.
Support
IntelliSafe includes driver support functions suchas Adaptive cruise control* which helps the driverto maintain an even speed combined with a pre-selected time interval to the vehicle ahead.
Pilot Assist2 helps the driver keep the vehicle inthe current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
Park Assist Pilot* helps the driver pull into andout of parking spaces.
Other examples of systems that can help thedriver are the Active main beam, Cross TrafficAlert (CTA)* and Blind Spot Information (BLIS)*systems.

Prevention
City Safety is a function intended to help preventaccidents. The function can help prevent or miti-gate a collision with pedestrians, cyclists, largeanimals or other vehicles. Light, sound and pulsa-tions in the brake pedal are provided to alert of a

Driver/passenger-side airbags1
As a supplement to the seat belts, the vehicle isequipped with driver and passenger side frontairbags.
Driver/passenger side front airbags.
In a frontal collision, the airbags help protect thedriver's and passenger's head, face and chestand the driver's knees and legs.
A collision of a sufficiently violent force will trig-ger the sensors and one or more airbags willinflate. The airbag helps cushion the initial impactof the collision for the passenger. The airbagdeflates when compressed by the collision. Asmall amount of powder will also be releasedfrom the airbag. This may appear to be smokeand is normal. The entire process, from inflation
to deflation of the airbag, occurs within tenths ofa second.

NOTE
The sensors react differently depending onthe circumstances of the accident andwhether or not the seat belt is used. Does notapply to all belt positions.
In some accident situations, only one (ornone) of the airbags will be deployed. Thesensors monitor the impact of the collisionand react accordingly to deploy one, severalor no airbags.

WARNING
The seat belt and the airbag work together. Ifthe seat belt is not used or is used incorrectly,the airbag may not provide the intended pro-tection in a collision.
To help prevent injury in the event the airbagis deployed, passengers should sit as uprightas possible, with their feet on the floor andtheir backs against the seat backrest.

WARNING
Volvo recommends contacting an authorizedVolvo workshop for repairs. Incorrectly per-formed repairs to the airbag system couldimpair function and lead to serious injury.
The front airbag system
The front airbag system includes gas generatorssurrounded by the airbags, and deceleration sen-sors that activate the gas generators, causing theairbags to be inflated with nitrogen gas.
As the movement of the seats' occupants com-presses the airbags, some of the gas is expelledat a controlled rate to provide better cushioning.The belt tensioners minimize slack in the seatbelts and are activated for occupants wearingtheir seat belts. The entire process, from inflationto deflation of the airbag, occurs within tenths ofa second.
The location of the front airbags is indicated bySRS AIRBAG embossed on the steering wheelpad and above the glove compartment, and bydecals on both sun visors and on the front andfar right side of the dash.
The driver's side front airbag is folded andlocated in the steering wheel hub.
The knee airbag is folded on the underside ofthe dashboard on the driver's side. The textAIRBAG is embossed on the panel.
The passenger's side front airbag is foldedbehind a panel located above the glove compart-ment.
1S90 Excellence Lounge does not have passenger airbags.

The parking sequence is cancelled
A parking sequence will be cancelled if:
the driver moves the steering wheel
the vehicle's speed exceeds 7 km/h (4 mph)
the driver taps Cancel in the center display
when the anti-lock brakes or the Electronicstability control are engaged - e.g. when awheel loses grip on a slippery road
when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
A message in the center display will explain whythe parking sequence was cancelled.

CAUTION
Under certain circumstances, PAP may not beable to find parking spaces – one reason maybe that the sensors are disrupted by externalsound sources that emit the same ultrasonicfrequencies that the system works with.
Examples of such sources include horns, wettires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensorsreduce their function and can make measure-ment impossible.

Driver responsibility
The driver should keep in mind that PAP is aparking aid ‒ not an infallible fully automatic sys-tem. The driver must always be prepared to takecontrol and cancel a parking sequence if neces-sary.
There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for determin-ing if the space suggested by PAP is suita-ble for parking.
Do not use PAP when using snow chains ora temporary spare tire.
Do not use PAP if there are any objects pro-truding from the vehicle.
Heavy rain or snowfall may inhibit PAP's abil-ity to accurately measure a parking space.
While searching and measuring the parkingspace, PAP may be unable to detect objectslocated far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle.
Use approved tires121 inflated to the correcttire pressure because this affects PAP's abil-ity to provide parking assistance.
PAP's 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 rims couldbe damaged by the curb during the parkingprocedure.
Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake sure that your vehicle is parallel to rel-evant parking spaces when PAP is measur-ing the parking space.

CAUTION
Switching to another approved wheel and/ortire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.
121"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

Tread wear indicator
The tread wear indicator shows the status of thetire's tread.
The tread wear indicator is a narrow elevatedstrip running across the tire's longitudinal treadgrooves. The letters TWI (Tread Wear Indicator)are visible on the side of the tire. When approxi-mately 1.6 mm (1/16 inch) is left on the tread,the tread will be at the same height as the treadwear indicator. Replace the tire as soon as possi-ble. Tires with low tread offer very poor traction inrain or snow.

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 or without studs, are exceptionsand may use a lower SS. When winter tires areinstalled, 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.
M 130 km/h (81 mph)
Q 160 km/h (100 mph)
T190 km/h (118 mph)

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUSTCONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES.
Quality grades can be found, where applica-ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample:
Treadwear 200 Traction AA Temperature A

TREADWEAR
The treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.

TRACTION
The traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance.
WARNING
The traction grade assigned to this tire isbased on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.

TEMPERATURE
The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.

WARNING
The temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.

Checking tire pressure
Correct inflation pressure helps improve drivingstability, save fuel and increase the service life ofthe tires.
Tire pressure decreases over time, which is nor-mal. Tire pressure also varies depending on theambient temperature. Driving on under-inflatedtires could cause the vehicle to overheat and leadto damage. Tire pressure affects traveling com-fort, road noise and driving characteristics.
Check the pressure in the tires every month. Usethe recommended inflation pressure for cold tiresfor optimal tire performance and wear. Under-inflated or over-inflated tires could cause uneventread wear.
Use an air pressure gauge and check the infla-tion pressure on all the tires, including the spare
tire4, at least once a month and before long trips.Volvo strongly recommends buying a reliable airpressure gauge, as the automatic gauges provi-ded at service stations may be inaccurate.

WARNING
Under-inflation is the most commoncause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
Under-inflated tires reduce the load car-rying capacity of your vehicle.

Cold tires
Inflation pressure should be checked when thetires are cold.
The tires are considered to be cold when theyhave the same temperature as the surrounding(ambient) air.
This temperature is normally reached after thevehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),the tires are considered to be warm. If you needto drive longer than that to inflate the tires, checkand record the inflation pressure of the tires firstand inflate accordingly when you arrive at thepump.
When the ambient temperature changes, so doesthe inflation pressure. A 10-degree temperaturedrop causes a corresponding drop in inflationpressure of 1 psi (7 kPa). Check the inflationpressure of the tires regularly and adjust to the
correct pressure, which can be found on the vehi-cle's tire information placard or certification label.
If you check inflation pressure when the tires arewarm, you should never release air. The tiresbecome warm after driving and it is normal forwarm tires to have an inflation pressure abovethe recommended pressure for cold tires. A warmtire with an inflation pressure equal to or underthe recommended pressure for cold tires couldbe significantly under-inflated.

Adjusting tire pressure
Tire pressure decreases over time, which is nor-mal. The tire pressure must therefore beadjusted to maintain the recommended tire pres-sure.
Use the recommended inflation pressure for coldtires for optimal tire performance and wear.

NOTE
To help prevent incorrect inflation pressure,pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.
1. Remove the valve cap from the tire and pressthe 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 recommended pres-sures for factory-mounted tires.
3.Screw the valve cap back on.
NOTE
After inflating a tire, always replace thevalve 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 thereare no nails or other embedded objects thatcould puncture the tire and cause air leak-age.
5. Check the sidewalls to make sure there areno gouges, cuts, bulges or other irregulari-ties.
6.Repeat this procedure for each tire, including
the spare tire5.
NOTE
If you have overfilled the tire, release air bypushing on the metal stem in the center ofthe valve. Then recheck the pressure withyour tire gauge.
Some spare tires require higher inflation pres-sure than the other tires. Consult the tireinflation pressure table or the inflation pres-sure placard.
