Driver distraction
A driver has a responsibility to do everything possible to ensure his or her own safety andthe safety of passengers in the vehicle andothers sharing the roadway. Avoiding distrac-tions is part of that responsibility. Driver distraction results from driver activities that are not directly related to controlling thevehicle in the driving environment. Your newVolvo is, or can be, equipped with many fea-ture-rich entertainment and communicationsystems. These include hands-free cellulartelephones, navigation systems, and multi-purpose audio systems. You may also ownother portable electronic devices for your ownconvenience. When used properly and safely,they enrich the driving experience. Improperlyused, any of these could cause a distraction. For all of these systems, we want to provide the following warning that reflects the strongVolvo concern for your safety. Never usethese devices or any feature of your vehicle ina way that distracts you from the task of driv-ing safely. Distraction can lead to a seriousaccident. In addition to this general warning,we offer the following guidance regardingspecific newer features that may be found inyour vehicle: •Never use a hand-held cellular telephone while driving. Some jurisdictions prohibit cellular telephone use by a driver whilethe vehicle is moving.
• If your vehicle is equipped with a naviga-tion system, set and make changes toyour travel itinerary only with the vehicleparked.
• Never program your audio system whilethe vehicle is moving. Program radio pre-sets with the vehicle parked, and useyour programmed presets to make radiouse quicker and simpler.
• Never use portable computers or per-sonal digital assistants while the vehicle ismoving.
Accessory installation
• We strongly recommend that Volvo own- ers install only genuine, Volvo-approvedaccessories, and that accessory installa-tions be performed only by a trained andqualified Volvo service technician.
• Genuine Volvo accessories are tested toensure compatibility with the perform-ance, safety, and emission systems inyour vehicle. Additionally, a trained andqualified Volvo service technician knowswhere accessories may and may not besafely installed in your Volvo. In all cases,please consult a trained and qualifiedVolvo service technician before installingany accessory in or on your vehicle. •
Accessories that have not been approvedby Volvo may or may not be specificallytested for compatibility with your vehicle.Additionally, an inexperienced installermay not be familiar with some of yourcar's systems.
• Any of your car's performance and safetysystems could be adversely affected ifyou install accessories that Volvo has nottested, or if you allow accessories to beinstalled by someone unfamiliar with yourvehicle.
• Damage caused by unapproved orimproperly installed accessories may notbe covered by your new vehicle warranty.See your Warranty and Service RecordsInformation booklet for more warrantyinformation. Volvo assumes no responsi-bility for death, injury, or expenses thatmay result from the installation of non-genuine accessories.

All Wheel Drive (AWD) – general information
Your Volvo can be equipped with an electron- ically controlled All Wheel Drive system*,which means that power is distributed auto-matically between the front and rear wheels.Under normal driving conditions, most of theengine's power is directed to the frontwheels. However, if there is any tendency forthe front wheels to spin, an electronicallycontrolled coupling distributes power to thewheels that have the best traction.
Tire dimensionsVolvo recommends that you always drive ontires of the same brand, size, construction(radial), tread pattern, load-, speed-, traction-,temperature-, and treadwear rating. Neverdrive on mixed tires, except for brief periodswhen the temporary spare tire is in use. Always use properly inflated tires of correct dimensions. Tire size and inflation pressuresare shown on the tire inflation pressure plac-ards, located on the driver's side B-pillar (thestructural member at the side of the vehicle,at the rear of the driver's door opening), or onthe inside of the fuel filler door on Canadianmodels.
Temporary SpareThe temporary spare tire is for temporary,low-speed, short-distance use only. Replaceit with a full-sized tire as soon as possible. Donot drive on the temporary spare at speedsabove 50 m.p.h. (80 km/h).
NOTE
Never install snow chains on a temporary spare.

Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
NOTE
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel spin by transferring power from a drivewheel that begins to lose traction to thewheel on the opposite side of the vehicle (onthe same axle). TC is most active at low speeds.This is one of DSTC's permanent functions and cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily switch off this function for maxi-mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (1) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2. Hold down the RESET button (2) to tog-
gle between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
• The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo- rarily been switched off.
• The stability control indicator light willilluminate and remain on until spincontrol has been reactivated.
• The spin control function is automati-cally enabled each time the engine isstarted.
•
DSTC ON indicates that all system
functions are active.
Active Yaw Control (AYC)This function helps maintain directional stabil- ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally. This is one of DSTC's permanent functions
and cannot be switched off.
WARNING
The car's handling and stability characte- ristics will be altered if the DSTC systemfunctions have been disabled.

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.
