Location of the towing eyelet
Attaching the towing eyelet
Attaching the towing eyeletThe towing eyelet is located under the floor of the cargo area, with the spare tire.This eyelet must be screwed into thepositions provided on the right sides ofeither the front or rear bumper (see illus-tration).
There are two different types of covers over the openings for the towing eyeletand they have to be opened differently.
• If the cover has a notch, insert a coin, etc., into the notch and pry open theedge of the cover. Open the covercompletely and remove it.
• If the cover has a mark along one edgeor in a corner, press the mark whileprying out the opposite side/cornerusing a coin, etc. Open the cover andremove it.
Screw the towing eyelet in place, first by hand and then using the tire iron until it issecurely in place. After the vehicle has been towed, the eyelet should be removed and returned to its stor-age location. Press the cover for the attachment point back into position.
WARNING
• When the vehicle is being towed, the ignition should be in mode
II (in mode
I , all of the vehicle's airbags are deac-
tivated). See page 87 for more infor-mation about ignition modes.
• Never remove the remote key from theignition slot when the vehicle is beingtowed. For vehicles with keyless drive,the remote key must remain inside thevehicle.
• The power brakes and power steeringwill not function when the engine is notrunning. Approximately 5 times morepressure will be required on the brakepedal and the steering wheel will beconsiderably harder to turn.
• The towing eyelets must not be usedfor pulling the vehicle out of a ditch orfor any similar purpose involvingsevere strain.

Towing the vehicle
1. With the remote key fully pressed into theignition slot 1
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 2
for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This willhelp prevent jarring movements of thevehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.CAUTION
General towing precautions:
• Please check with state and local authorities before attempting this typeof towing, as vehicles being towed aresubject to regulations regarding maxi-mum towing speed, length and type oftowing device, lighting, etc.
• If the vehicle's battery is dead, attachjumper cables (see page 123) to pro-vide current for releasing the electricparking brake and to move the gearselector from the
P position to N. If
this is not possible, see page 128 forinformation about manually overridingthe shiftlock system to move the gearselector from P to N.
• Maximum speed: 50 mph (80 km/h).Do not exceed the maximum allowabletowing speed.
• Maximum distance with front wheelson ground: 50 miles (80 km).
• The vehicle should only be towed inthe forward direction.
Having the vehicle towed by a tow truck
Call for professional help from an authorized towing company.Volvo recommends the useof flat bed equipment. The towing eyelet may be used to pull the vehicle onto a flatbed tow truck if:
• The angle of the tow truck’s ramp is not more than 12 degrees from a horizontalplane
• The vehicle’s wheels rotate freely and rollstraight ahead
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.

6. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
NOTE
Be sure that none of the other 12-volt sockets is being used while the compres-sor is in operation.
7. Start the vehicle’s engine.
WARNING
The vehicle´s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be sure thevehicle is parked in a well ventilated place,or outdoors, before using the system.
8. Start the tire sealing system’s compres- sor by pressing the on/off switch to posi- tion I.
WARNING
• Never stand next to the tire being infla- ted when the compressor is in opera-tion.
• If cracks, bubbles, etc. form on the tire,switch off the compressor immediately.
• If there is visible damage to the sidewallor the rim, the tire cannot be repaired.The vehicle should not be driven if thisoccurs. Contact a towing service orVolvo On Call Roadside Assistance ifapplicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approxi-mately 88 psi (6 bar) while the sealingcompound is being pumped into the tire.The pressure should return to a normallevel after approximately 30 seconds.
9. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch off the compressor briefly to get aclear reading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately sevenminutes, turn off the compressor. In thiscase, the hole is too large to be sealed andthe vehicle should not be driven.
10. Switch off the compressor and discon- nect the electrical wire from the 12-volt socket.
11. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
12. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum

Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle’s engine.WARNING
• The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor (pressthe on/off switch to position I). If neces-sary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct
inflation pressure has been reached.
10. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
11. Disconnect the electrical wire from the
12-volt socket.

08 Wheels and tires
Tire Pressure Monitoring System (TPMS)
08
* Option/accessory, for more information, see Introduction.327
NOTE
• If you change to tires with a different recommended inflation pressure, theTPMS system must be recalibrated tothese tires. On U.S. models, this mustbe done by a trained and qualifiedVolvo service technician. On Canadianmodels, see the following section"Recalibrating TPMS."
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
Recalibrating TPMS (Canadian models only)*
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 307), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. This is done in the vehicle's menu system. See page 199 for a description of the menusystem. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and put the ignition in mode I or II (see
page 87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Press OK/MENU , select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 10 minutes.
> When the calibration message is nolonger displayed, TPMS has been recalibrated to the new inflation pres-sure.
Activating/deactivating TPMS
(Canadian models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.

Owner maintenance
Periodic maintenance requirements and inter- vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires.Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min"and "max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult yourVolvo retailer for additional information.
As needed:Wash the car, including the undercarriage, to reduce wear that can be caused by a buildupof dirt, and corrosion that can be caused bysalt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from otherplaces where they may collect.
NOTE
Complete service information for qualified technicians is available online for purchaseor subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments points should be used. They are specially reinforced to bear theweight of the vehicle. A garage jack can alsobe placed under the front of the engine sup-port frame. Take care not to damage thesplash guard under the engine. Ensure thatthe jack is positioned so that the vehicle can-not slide off it. Always use axle stands or sim-ilar structures. If a two-post hoist is used to lift the vehicle, the front and rear lift arm pads should becentered under the reinforced lift plates onthe inboard edge of the sill rail (see illustra-tion).
Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD 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 tempo-rary. OBD II will store a message about anyfault.

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 waslit, but went out without any action onyour part, OBD II will still have a recordedfault. Your vehicle may pass or fail,depending on the inspection practices inyour area.
• If you had recent service that requireddisconnecting the battery, OBD II diag-nostic information may be incompleteand "not ready" for inspection. A vehiclethat is not ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit – orwas lit but went out without service, have your vehicle diagnosed and, if necessary,serviced by a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.A half-hour trip of mixed stop-and-go/highway driving is typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
• Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
