430system. Repeated use of leaded gasoline will lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicleinspection programs will make detection ofmisfueling easier, possibly resulting in emis-sion test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tricar-bonyl (MMT). If such fuels are used, yourEmission Control System performancemay be affected, and the Check EngineLight (malfunction indicator light) locatedon your instrument panel may light. If thisoccurs, please return your vehicle to atrained and qualified Volvo service techni-cian 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 lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. To
meet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo permits the use of the following "oxy- genated" fuels. However, the specified octaneratings must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred toas Ethyl alcohol, or "Gasohol". Ethers - MTBE/ETBE: Fuels containing up to 22% MTBE/ETBE by volume may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriorationand can damage critical parts in the fuel sys-tem. Such damage may not be covered underthe New Vehicle Limited Warranty.

Trailer Stability Assist
*
Trailer Stability Assist (TSA 11
) is a function
designed to help stabilize a vehicle that is towing a trailer when the vehicle and trailerhave begun to sway. The function is part of the Electronic Stability Control system ESC 12
.
Reasons for swayingA vehicle towing a trailer may begin to sway for various reasons. Normally this only occursat high speeds. However, if the trailer is over-loaded or unevenly distributed, e.g. too farback, there is a risk of swaying even at lowspeeds. Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden, strong crosswind.
The vehicle and trailer are traveling on anuneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicleand trailer difficult to control and there is a riskof swerving into oncoming traffic or driving offthe road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitorsthe vehicle's movements, particularly lateral movements. If swaying is detected, the brakesare applied individually on the front wheels,which has a stabilizing effect on the vehicleand trailer. This is often enough to enable thedriver to regain control of the vehicle. If the Trailer Stability Assist function's first attempt is not adequate to stop the swayingmotion, the brakes are applied on all wheelsand engine power is temporarily reduced. Asthe swaying motion begins to decrease andthe vehicle and trailer have once againbecome stable, TSA stops regulating thebrakes/engine power and the driver regainscontrol of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the driver selects the sport mode by deactivat- ing
ESC in the center display's menu sys-
tem.
Trailer Stability Assist may not intervene if the driver tries to compensate for the swayingmotion by moving the steering wheel rapidly,because the system will then not be able todetermine if it is the trailer or the driver caus-ing the swaying.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Never attempt to tow a Twin Engine vehicle behind another vehicle as this could damagethe electric motor. The vehicle must instead belifted onto a tow truck and transported with allfour wheels on the bed or lifting platform ofthe truck (no wheels may touch the road).
Towing another vehicleTowing another vehicle requires a lot of power - use the Constant AWD drive mode. This
helps charge the hybrid battery and improve the vehicle's driving and roadholding characte-ristics. Before towing another vehicle, check applica- ble speed limit regulations.
Jump startingNever attempt to tow the vehicle to start theengine, as this could damage the electricmotor. Use an auxiliary battery if the start bat-tery's charge level is so low that the enginecannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motorand three-way catalytic converter.

WHEELS AND TIRES

Tire sealing system14
The temporary tire sealing system can be used to seal a puncture in a tire or to checkand adjust the pressure in the tire. Models equipped with a spare wheel 15
do not
have the tire sealing system.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
The tire sealing system consists of a compres- sor and a bottle containing sealing compound.The sealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but maynot be able to fully seal tires with punctu-res in the sidewall. Do not use the tire seal-ing system on tires with large tears, cracksor similar damage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the trunk.
Sealing compound expiration dateThe sealing compound bottle must be replaced if its expiration date has passed (seethe decal on the bottle). Handle the old bottleas hazardous waste.

16. Check the inflation pressure on the air
pressure gauge.
If the pressure is under 1.3 bar (19 psi), the tire is not sufficiently sealed. Thevehicle should not be driven. Call road-side assistance to have the vehicletowed.
If the inflation pressure is higher than1.3 bar (19 psi), the tire must be inflatedto the inflation pressure specified onthe tire pressure decal on the driver'sside door pillar (1 bar = 100 kPa =14.5 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest authorized Volvo workshop to have the tirereplaced/repaired. Inform the workshop thatthe tire contains sealing compound. The sealing compound bottle and the hose must be replaced after use. Volvo recom-mends contacting an authorized Volvo work-shop for replacement.
WARNING
After using the tire sealing system, the vehicle should not be driven farther thanapproximately 200 km (120 miles).
NOTE
The compressor is an electric device. Fol- low local regulations for disposal.

On-board Diagnostic SystemOBD II is part of your vehicle's computerized engine management system. It stores diag-nostic information about your vehicle's emis-sion controls. It can light the Check Enginelight (MIL) if it detects an emission control"fault." A "fault" is a component or systemthat is not performing within an expectedrange. A fault may be permanent or temporary.OBD II will store a message about any fault.
Emission inspection readiness
How do states use
OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector canthen read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec- tion for any of the following reasons: If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit,but went out without any action on yourpart, OBD II will still have a recorded fault.Your vehicle may pass or fail, dependingon the inspection practices in your area.
If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
