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.

Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of func-tions designed to help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
CAUTION
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.
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 functionsand cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating.
Trailer Stability Assist – TSA
1Trailer Stability Assist helps stabilize a vehiclethat is towing a trailer when the vehicle andtrailer have begun to sway. See page 295 formore information. This system is automatically deactivated if the driver selects
Sport mode.
Operation
Sport modeThe stability system is always activated and cannot be switched off. However, the driver can select Sport mode,
which offers more active driving characteris- tics. In this mode, the engine managementsystem monitors movement of the acceleratorpedal and steering wheel for sportier driving by allowing more lateral movement of the rearwheels before DSTC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use
Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, DSTC will also activate to helpstabilize the vehicle. To switch to Sport mode:
1. Press the My Car button in the center
console control panel and select
My
XC70
DSTC in the menu.
2. Unselect the symbol and leave the menu by pressing EXIT.
> This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. DSTC will return to normalmode when the engine is restarted.

• Press
.
This symbol and the marking for the set speed with change colors from green to
white. The previously set speed and time interval are resumed by pressing
.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:
• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability and traction control system (DSTC). Ifthis system is not functioning properly, ACCwill switch off automatically. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h) 4
• the wheels lose traction •
brake temperature is high
• the radar sensor is obstructed by, for example, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicleIf your vehicle’s speed is being regulated by ACC and the driver indicates that he/shewould like to pass the vehicle ahead by usingthe left turn signal, ACC can assist by accel-
erating briefly. This function is active at speeds above approximately 45 mph (70 km/h).

Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun tosway and is part of the Dynamic Stability andTraction Control system (DSTC). See page142 for information on DSTC.
FunctionA vehicle towing a trailer may begin to swayfor various reasons. Normally this only occursat high speeds but, for example, if the traileris overloaded or if the load is unevenly dis-tributed in the trailer, there is risk of swayingat speeds between approximately 45-55 mph(70-90 km/h). Swaying may be caused by factors such as: •The vehicle and trailer are hit by a sud- den, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The DSTC symbol (
) in the instru-
ment panel will flash when TSA is working
• If the driver switches off the DSTC sys- tem's Spin Control function, TSA will also be switched off (but will be on again thenext time the engine is started)
• TSA may not intervene when the vehicleand trailer begin to sway if the driver triesto compensate for the swaying motion bymoving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi- cult to stop, which makes it difficult to controlthe vehicle and trailer. The TSA system continuously monitors the vehicle's movements, particularly lateralmovement. If the system detects a tendencyto sway, the brakes are applied individuallyon the front wheels, which has a stabilizingeffect on the vehicle and trailer. This is oftenenough to enable the driver to regain controlof the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of thewheels on the vehicle and on the trailer if it isequipped with brakes, and engine power istemporarily reduced. As the swaying motionbegins to decrease and the vehicle-trailerhave once again become stable, TSA will nostop regulating the brakes/engine power andthe driver regains control of the vehicle.

Quality grading information
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(1 1/2) times as well on the governmentcourse as a tire graded 100. The relative per-formance of tires depends upon the actualconditions of their use, however, and manydepart significantly from the norm due to var-iation in driving habits, maintenance practicesand differences in road characteristics andclimate.
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. The traction grade assigned to this tireis based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
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.
