Geartronic: steering wheel paddles*In addition to the manual gearshift function using the gear selector, this option makes itpossible to manually shift gears from thesteering wheel.
Steering-wheel mounted gear shift paddles
" – ": Shift down to a lower gear.
"+ ": Shift up to a higher gear.
In order to shift gears with the paddles, they have to first be activated. The gear selector
can be in either the D or S position. Activating the paddles:
• Pull either paddle toward the steering wheel and release it; the
D in the instru- ment panel will change to the number ofthe gear currently being used.
Shifting gears:
• Pull the paddle toward the steering wheeland release it.
NOTE
If the gear selector was in
D when paddle
shifting was activated ( D changed to the
number of the gear being used), the trans- mission will automatically revert to D after
approximately 5 seconds if the paddlesare not used to shift gears. This will not occur:
• during active driving (e.g., on a wind- ing road, while accelerating, etc)
• if the gear selector was in
S when the
paddles were activated
If the transmission reverts to D, the pad-
dles will have to be reactivated (pull either paddle toward the steering wheel andrelease it) before they can be used to shiftgears again. The paddles can also be manually deacti- vated by pulling both paddles toward thesteering wheel and holding them until thegear number shown in the instrumentpanel changes to D.
Geartronic: Sport mode (S) 3This transmission mode provides sportier shifting characteristics and enables a moreactive driving style by making it possible todrive at higher rpm in each gear before shift-ing up. The engine also responds faster whenthe accelerator pedal is pressed. To access Sport mode from Drive (
D), move
the gear selector to the left. The transmission will not switch to manual shifting mode untilthe gear selector is moved forward or rear-ward toward + or –. Sport mode can be selected any time.
NOTE
• On vehicles equipped with Sport mode, the transmission symbol in themain instrument panel will changefrom
D to S when the gear selector is
moved to the manual shifting mode. Ifthe gear selector is moved toward "+"or "-", the number of the gear currentlybeing used will be displayed, seepage 75).
• Please be aware that using Sportmode may result in a slight decrease infuel economy. Driving in
D can help
improve fuel economy.

Geartronic: starting on slippery
surfaces
Selecting 3rd gear in Geartronic’s manual shifting mode can help provide better tractionwhen starting off on slippery surfaces. To doso:
1. Depress the brake pedal and move the gear selector to the side from D toward
+S– .
2. Press the gear selector forward and release it (this selects 2nd gear). Press the selector forward again and release itto select 3rd gear. The optional steeringwheel paddles can also be used; see theprevious section "Geartronic: steeringwheel paddles."
3. Release the brake pedal and press gently on the accelerator pedal.
Shiftlock override
If the vehicle cannot be driven, for example because of a dead battery, the gear selectormust be moved from the P position before
the vehicle can be moved 4
.
Lift away the rubber mat on the floor of the storage compartment behind the cen-ter console to expose the small openingfor overriding the shiftlock system.
Insert the key blade into the opening. Press the key blade down as far as possi-ble and keep it held down.
Move the gear selector from the P posi-
tion. For information on the key blade, see page 60.
All Wheel Drive: AWD 5
Your Volvo can be equipped with permanent All Wheel Drive, which means that power isdistributed automatically between the frontand rear wheels. Under normal driving condi-tions, most of the engine's power is directedto the front wheels. However, if there is anytendency for the front wheels to spin, an elec-tronically controlled coupling distributespower to the wheels that have the best trac-tion.

Introduction
Eco is a function 1
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuelconsumption.
When Eco is activated, thefollowing functions are modi-fied:
•The automatic transmission's shifting points
• The engine management system andaccelerator pedal response
• Stop/stop function (see page 131): theengine can auto-stop before the vehiclehas come to a full stop
• Eco Coast functionality is activated:engine braking is disabled
• Climate system settings: certain functions(e.g., air conditioning) will be temporarilyreduced or deactivated
NOTE
When Eco is activated, several climate system parameters are changed and thefunction of certain current-consuming sys-tems will be reduced. Pressing the
AC button will reset the cli-
mate system but at a reduced level.
Function
ECO On/Off button in the center console
ECO symbol in the instrument panel
When the engine is switched off, ECO is deactivated and must be reactivated each time the engine is started (with the exceptionof certain engines). The
ECO symbol will be displayed in the
instrument panel and the indicator light in the ECO button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, the ECO symbol will not be
displayed in the instrument panel and the indicator lightin the ECO button will be off.
The function will remaindeactivated until the buttonis pressed again.
Eco CoastEco Coast is an integral part of the Eco func- tion and essentially deactivates engine brak-ing, allowing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should primarily be used when the vehicle cancoast as far as possible.

Adaptive Cruise Control (ACC)*
04
150* Option/accessory, for more information, see Introduction.
Introduction
Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by main-taining a set speed or a set time interval tothe vehicle ahead. It is primarily intended foruse on long straight roads in steady traffic,such as on highways and other main roads. When the driver has set the desired speed and the time interval to the vehicle ahead,ACC functions as follows:
• If there are no other vehicles in the lane ahead of you, your vehicle will travel atthe set speed.
• If ACC's radar sensor detects a slowermoving vehicle in the lane ahead, the sys-tem will adapt your vehicle's speed tohelp maintain the set time interval to thevehicle ahead. When there are no longerslower moving vehicles ahead, your vehi-cle will accelerate to resume the setspeed.
If ACC is switched off completely or in standby mode and your vehicle comes tooclose to another vehicle ahead, the driver willbe warned by the Distance Alert system (seepage 161).WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic,weather and road conditions. The"Function" section provides informa-tion about limitations that the drivermust be aware of before using thisfeature.
• This system is designed to be a sup-plementary driving aid. It is not, how-ever, intended to replace the driver'sattention and judgement. The driver isresponsible for maintaining a safe dis-tance and speed and must intervene ifAdaptive Cruise Control does notmaintain a suitable speed or suitabledistance to the vehicle ahead.
• Maintenance of ACC components mayonly be performed by a trained andqualified Volvo technician.

Adaptive Cruise Control consists of: • A cruise control system to maintain a set speed
• A system to maintain a set distance to thevehicle ahead, which is expressed as atime interval. For example, you canchoose to remain approximately 2 sec-onds behind the vehicle ahead. Theactual distance required to maintain a

2-second interval will vary according the speed of the vehicles.
WARNING
•
Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor.Your vehicle's speed is regulated by acceler-ating and braking. The brakes may emit asound when they are being modulated by the adaptive cruise control system. This is nor-mal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates thebrakes. Do not rest your foot under thebrake pedal.
The ACC system is designed to smoothly regulate speed. However, the driver mustapply the brakes in situations that requireimmediate braking. This applies when thereare great differences in speed between vehi-cles, or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not atall, see page 157.
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if thevehicle's speed falls below 18 mph (30 km/h)or if engine speed (rpm) becomes too low,ACC disengages (goes into standby mode)and will no longer modulate the brakes. Thedriver will then have to maintain a safe dis-tance to the vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off com-pletely, the brakes will not be modulatedautomatically. The driver must assume fullcontrol over the vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% ofthe vehicle's total braking capacity. In situa-tions requiring more brake force than ACCcan provide and if the driver does not applythe brakes, an audible signal from the Colli-sion Warning system will sound and warninglight will illuminate (see page 171) in thewindshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.

WARNING
Please be aware that this function will also cause the vehicle to accelerate briefly incertain situations other than passinganother vehicle, for example using the leftturn signal to indicate a lane change or aturn toward a highway exit at speedsabove approximately 45 mph (70 km/h).
Turning ACC off completely
•
From standby mode, press once.
• From active mode, press
twice.
The set speed and time interval are then cleared from the system's memory and can- not be resumed by pressing

> This activates the standard cruise control function (see page 148).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC offcompletely." The next time the system isswitched on, ACC will be reactivated.
Queue Assist
IntroductionQueue Assist is an added ACC feature that is linked to your vehicle's automatic transmis-sion. Queue Assist consists of the following func- tions: • Enhanced speed interval (including when the vehicle is at a complete stop or is moving at speed below 18 mph(30 km/h))
• Automatic standby mode when ACCchanges target vehicles
• No automatic braking when at a standstill
• The parking brake is applied automati-cally
Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC canmaintain a set speed/distance to a vehicleahead down to a standstill. Queue Assistconsists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the driver's seat belt must be fastened beforeACC can be put in active mode. If the driv-er's seat belt is taken off or if the driver'sdoor is opened, ACC will return to standbymode.
Your vehicle can maintain the set time interval to the vehicle ahead at any permissiblespeed, including a complete stop. In order to activate ACC at speeds below 18 mph (30 km/h):
