28 goal. In addition to continuous environmental refinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in 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.

IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regarding vehicle 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.
SupportIntelliSafe includes driver support functions such as Adaptive cruise control * which helps the driver
to maintain an even speed combined with a pre- selected time interval to the vehicle ahead. Pilot Assist 4
helps the driver keep the vehicle in
the current traffic lane by providing steering assistance and maintaining an even speed and aset time interval to the vehicle ahead. Park Assist Pilot * helps the driver pull into and
out of parking spaces. Other examples of systems that can help the driver are the Active main beam, Cross Traffic Alert (CTA) * and Blind Spot Information (BLIS) *
systems.
PreventionCity Safety is a function intended to help prevent accidents. 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

Occupant weight sensor
The Occupant Weight Sensor (OWS) is designed to meet the regulatory requirements ofFederal Motor Vehicle Safety Standard (FMVSS)208 and is designed to disable (will not inflate)the passenger's side front airbag under certainconditions.
Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than 140 cm (4 feet7 inches) be seated in the back seat of any vehi-cle with a front passenger side airbag and beproperly restrained for their size and weight. The OWS works with sensors that are part of the front passenger's seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the passeng- er's side front airbag should be enabled (mayinflate) or disabled (will not inflate). The OWS will disable (will not inflate) the pas- senger's side front airbag when:
• the front passenger's seat is unoccupied, orhas small/medium objects in the front seat,
• the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
• the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
• the system determines that a small child ispresent in a booster seat,
• a front passenger takes his/her weight off ofthe seat for a period of time,
• a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.

NOTE
When the ignition is switched on, the OWS indicator light will illuminate for several sec-onds while the system performs a self-diag-nostic test.
However, if a fault is detected in the system:
• The OWS indicator light will stay on
• The SRS warning light will come on and stay on and a text message will be displayed.
WARNING
If a fault in the system is detected and indi- cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.
WARNING
•Never try to open, remove or repair any components in the OWS system. Thiscould cause the system to malfunction.Maintenance or repairs should only becarried out by an a trained and qualifiedVolvo service technician.
• The front passenger's seat should not bemodified in any way. This could reducepressure on the seat cushion, whichmight interfere with the OWS system'sfunction.

•Opening/closing the fuel filler door (p. 427)
Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (gasoline with detergent additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo recommends not using external fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic con- verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel.

3. Select
Disable Leveling Control.
The vehicle's location and ground clearance determine if it can be lifted onto a tow truck. Ifthe incline of the tow truck is too steep or if theground clearance under the vehicle is insufficient,attempting to pull it up may result in damage. Inthis case, the vehicle should only be lifted withthe tow truck's lifting equipment.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted onto the bedof the truck.
CAUTION
The towing eyelet is only intended for towing on roads, and must not be used to pull vehi-
cles from ditches or any similar purpose involving severe strain. Call a tow truck forprofessional assistance.
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.

Tire direction of rotation
Tires with tread designed to roll in only one direction are marked with an arrow on the side-wall.
The arrow shows the tire's direction of rotation.
• The tire should maintain the same direction of rotation throughout its service life.
• Tires should only be moved between thefront and back, never from right to left or viceversa.
• Incorrectly mounted tires impair the vehicle'sbraking properties and ability to force asiderain, snow and slush.
• The tires with the most tread should alwaysbe mounted on the rear wheels to helpreduce the risk of skidding.
NOTE
Use tires of the same type, dimensions and make (manufacturer) on each axle.

This sequence will continue upon subse-quent vehicle start-ups as long as the malfunc-tion exists. When the malfunction indicator is illu-minated, the system may not be able to detect orsignal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressurewarning symbol is shown in the instrument panelalong with a message.

Action when warned of low tirepressure
When the tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), detectslow pressure in one or more of the vehicle'stires, the driver will be alerted that action is nee-ded.
If the system's indicator symbol illumi- nates and the message Tire pressure
low is displayed, check the tire pres-
sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tires using a tire pressure gauge.
3. Inflate the tire to the correct pressure (see the tire pressure decal on the driver's side door pillar).
4. Through calibration of the system via the center display after the tire pressure hasbeen adjusted. Please be aware that the indicator symbol will not go out until the low tire pressure hasbeen corrected and the system has beenrecalibrated.
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.
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.
WARNING
•Incorrect inflation pressure could lead to tire failure, which could cause the driverto lose control of the vehicle.
• The system cannot predict sudden tiredamage.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary dependingon engine type. When driving with snow tires, thecorrect type of tires must be mounted on all fourwheels.
NOTE
Contact a Volvo dealer for advice on the best choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow tires, mark the tires according to which side they were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving 500–1000 km (300–600 miles) slowly and gen-tly to help the studs settle properly in the tires.This gives the tire, and especially the studs, alonger service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tiresthan summer conditions. Volvo therefore recom-mends not driving on snow tires that have a treaddepth of less than 4 mm (0.15 inch).

Snow chains
Using snow chains and/or snow tires can help improve traction in winter driving conditions.
WARNING
Use Volvo genuine snow chains or equivalent snow chains that are suitable for the vehicle model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom- mends contacting an authorized Volvo work-shop. Use of the wrong snow chains couldcause serious damage to the vehicle andresult in an accident.
