> The indicator (3) shows the current time interval.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val.
One bar between the vehicles represents a timeinterval of approximately 1 second; 5 bars isapproximately 3 seconds. The same symbol appears if Adaptive Cruise Control is activated.
NOTE
• The greater the vehicles' speed, the greater the
distance between them for a
set time interval.
• The set time interval is also used by Adaptive Cruise Control
*.
• Only use time intervals permitted by local traffic regulations.

Distance Alert * limitations
Distance Alert uses the same radar sensor as Adaptive Cruise Control * and has several limita-
tions.
WARNING
• The radar sensor has a limited field of vision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see.

Changing Adaptive Cruise Control (ACC) speed
ACC makes it possible to set various speeds.
Changing a set speed
Function buttons and symbols
–Change a set speed by pressing the (1)
or — (3) buttons briefly or by pressing and
holding them:
• Press briefly
: changes speed in
+/– 5 mph (+/– 5 km/h) increments. Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
• Press and hold
: changes the speed
+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4) has moved to the desiredspeed. If speed is increased by pressing the accelerator pedal before the
button is pressed, the vehi-
cle's speed when the button is pressed will become the set speed assuming that the accel-erator pedal is still depressed when the button ispressed. A temporary increase in speed, such as when passing another vehicle, does not affect the ACCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released. The Adaptive Cruise Control can follow another vehicle from a standstill up to 125 mph(200 km/h). Always observe posted speed limits. The lowest speed that can be set for ACC is
20 mph (30 km/h). However, ACC can monitor and react to the speed of the vehicle ahead downto a standstill. The highest speed that can be set/stored is approx. 125 mph (200 km/h). Always observeposted speed limits.

Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead (a targetvehicle).
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.

Distance/time indicator
–Press buttons (1) or (2) to reduce or increase the time interval.
> The distance/time indicator (3) shows the
current time interval.
In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly. • If ACC does not seem to react when it is put in active mode, this may be because the set time interval to the vehicle ahead does notallow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
• Only use time intervals permitted by localtraffic regulations.
WARNING
•
Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Passing Assistance with Adaptive Cruise Control or Pilot Assist
ACC or Pilot Assist can assist the driver when passing other vehicles.
How passing assistance worksWhen ACC or Pilot Assist is following another vehicle and the driver indicates that he/she isabout to pass that vehicle by using the left turnsignal, ACC or Pilot Assist will begin acceleratingtoward the vehicle ahead before your vehicle hasmoved into the passing lane. The function will then delay a speed reduction to avoid early braking as your vehicle approachesthe slower-moving vehicle. The function is active until your vehicle has passed the other vehicle.
WARNING
Be aware that this function may be activated in situations other than when passing a vehi-cle, such as if the turn signal is used to indi-cate a lane change or to indicate a turn. Thevehicle will accelerate briefly.

DRIVER SUPPORT
278sensor, the system may apply the brakes in your vehicle suddenly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same traffic lane at a preset time intervalset by the driver. If the radar sensor does notdetect a vehicle ahead, the vehicle will insteadmaintain the speed set by the driver. This will alsobe the case if a vehicle ahead accelerates andexceeds the set speed.
• Pilot Assist can follow another vehicle from astandstill up to a speed of approx. 125 mph(200 km/h)
• Pilot Assist can provide steering assistancefrom very low speeds up to approx. 87 mph(140 km/h).
Never exceed posted speed limits.
WARNING
• Pilot Assist is not a collision avoidance system. The driver must react if the sys-tem does not detect another vehicle.
• Pilot Assist does not react to people, ani-mals, stationary objects, small vehicles(such as bicycles and motorcycles), lowtrailers and slow moving, parked orapproaching vehicles.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in areas withintersections, in slippery conditions, whenthere is a great deal of water or slush onthe road, during heavy rain or snow, inpoor visibility, on winding roads, on high-way on- or off-ramps or if the vehicle istowing a trailer, boat, etc.
NOTE
•Pilot Assist maintenance should only be carried out by a trained and qualifiedVolvo service technician.
• Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.

In order to follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
• If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

If the driving pattern becomes noticeably erratic, the driver willbe alerted by an audible signal and
Driver Alert Time for a
break will appear in the instru-
ment panel along with a sym- bol.
The warning will be repeated if the driving patterndoes not change.
WARNING
• DAC is not intended to extend the dura- tion of driving. Always plan breaks at reg-ular intervals to help remain alert.
• A warning from DAC should not beignored. A driver may not be aware ofhow fatigued he/she has become.
• In certain cases, fatigue may not affectthe driver

sidewall (see the illustration). A tire with e.g., visi- ble cracks or discoloration should be replacedimmediately.
Tire economy
•
Maintain correct tire pressure.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should only be moved from front to rear or vice versa.They should never be rotated left toright/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
• Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off the floor orplaced on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not besuspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
• Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.
