Uniform Tire Quality Grading

189
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES Quality grades can be found, where appli- cable, on the tire sidewall between thetread shoulder and maximum sectionwidth. For example: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when tes-ted under controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half (11/2) times as well on the government courseas a tire graded 100. The relative perform-ance of tires depends upon the actual condi-tions of their use, however, and many departsignificantly from the norm due to variation indriving habits, maintenance practices and dif-ferences in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform-ance.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a minimum level of perform-ance that all passenger vehicle tires mustmeet under the Federal Motor Safety Stand-ard No. 109. Grades B and A represent higherlevels of performance on the laboratory testwheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly infla-ted and not overloaded. Excessive speed,under-inflation, or excessive loading, eitherseparately or in combination, can causeheat buildup and tire failure.

Tire Pressure Monitoring System (TPMS)
07
203
The tire pressure monitoring system
1
uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe vehicle.
USA – FCC ID: MRXG403MA4 A
This device complies with part 15 of the
FCC rules. Operation is subject to the fol- lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation. When low inflation pressure is detected, TPMS will light up the tire pressure warn-ing light (also referred to as a telltale) in theinstrument panel (see page 61), and willdisplay a message in the text window. Thewording of this message is determined bythe degree of inflation pressure loss.
A On certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS will light up the tire pressure warning light
(also referred to as a telltale) in the instrument panel and will display one of the following messages in the text window:
LOW
TIRE PRESS. CHECK TIRES or VERY LOW
TIRE PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them to the proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life,and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioning

properly. Always check the TPMS malfunc- tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to function prop-erly.
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation pressure table inthis chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has been displayed, and the tire pressurewarning light has come on:
1. Use a tire pressure gauge to check theinflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the table see page 183).
3. Drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and thewarning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
Changing wheels with TPMSPlease note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
• Only the factory-mounted wheels are equipped with TPMS sensors in thevalves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors are mounted on the vehicle,
TIRE PRESS
SYST. SERVICE REQUIRED will be dis-
played each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes ormore.
• Once TPMS sensors are properly instal-led, the warning message should notreappear.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle. Volvo does not recommend movingsensors back and forth between sets ofwheels.
NOTE
If a tire is changed or if the TPMS sensor is moved to another wheel, the sensor’svalve and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
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 183), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and turn the ignition key to position I or II
(see page 145 for additional information).
3. Turn the thumb wheel on the left-side steering wheel lever until
Tire pressure
Calibration appears in the display.

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 vehicle is refueled
•Check the engine oil level
• Clean the windshield, windshield wipers, headlights, and tail lights
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 atrained and qualified Volvo service techni-cian for additional information.
As needed
•
Wash the vehicle, including the undercar-riage, to reduce wear that can be causedby a buildup of dirt, and corrosion thatcan be caused by salt residues.

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 avehicle's OBD II system. The inspector can then 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, haveyour 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 the

Note the following before you begin work- ing on your vehicle:
Battery
•
Ensure that the battery cables are cor- rectly connected and tightened.
• Never disconnect the battery when theengine is running (e.g., when replacingthe battery).
• Never use a fast charger to charge thebattery. The battery cables should be dis-connected when recharging.
• The battery contains acid that is both cor-rosive and poisonous. It is important thatthe battery is handled in an environmen-tally friendly way. See page 227 for moreinformation on handling the battery.
Hoisting the vehicle
G027001
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 (see the illustration). Agarage jack can also be placed under thefront of the engine support frame. Take carenot to damage the splash guard under theengine. Ensure that the jack is positioned sothat the vehicle cannot slide off it. Always useaxle stands or similar structures. The vehi-cle's gross vehicle weight is between5770 lbs (2630 kg) and 6080 lbs (2760 kg).Use a jack and stands rated for this weight. 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).
WARNING
The ignition system has very high voltage! The voltage in the ignition system is dan- gerous! Do not touch spark plugs, ignition cables or the ignition coil when the engine is run-ning or the ignition is switched on! The ignition should be switched off when: •
Conducting engine tests.
• Replacing parts in the ignition system, such as spark plugs, ignition coil, dis-tributor, ignition cables, etc.
WARNING
Never
try to repair any part of the SRS/
SIPS/WHIPS/IC systems yourself. Any interference in the system could causemalfunction and serious injury. Any workshould only be performed by an authorizedVolvo workshop.

Belt check
Check the belt regularly to make sure it is in good condition and is clean. A worn or dirtybelt can cause poor cooling and low alterna-tor output as well as impair the operation ofthe power steering and the air conditioningunit.
NOTE
The drive belt is equipped with a self-ten- sioning mechanism and requires noadjustment between changes.
WARNING
The engine must not be running when this check is performed.
Check coolant level
The cooling system must be filled with cool- ant and not leak to operate at maximum effi-ciency. Check the coolant level regularly. Thelevel should be between the MAX and MIN
marks on the expansion tank. The checkshould be made with particular thoroughnesswhen the engine is new or when the coolingsystem has been drained. Do not remove the filler cap other than for topping up with coolant. Frequent removalmay prevent coolant circulation between the engine and the expansion tank during enginewarm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. Do not top off with water only. This reduces the rust-protective and antifreeze qualities ofthe coolant and has a lower boiling point. Itcan also cause damage to the cooling systemif it should freeze. Top off with Volvo GenuineCoolant/Antifreeze only (a 50/50 mix of waterand antifreeze.
CAUTION
The cooling system must always be kept filled to the correct level. If it is not keptfilled, there can be high local temperaturesin the engine which could result in dam-age. Different types of antifreeze/coolantmay not be mixed.
WARNING
•
Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
