Gear indicatorThe gear currently being used is displayed on the rightside of the instrument panel. The " S" symbol turns orange
if Sport mode is being used.
Reverse: position RThe vehicle must be stationary when position R is selected.
Neutral: position NNo gear is engaged and the engine can bestarted with the gear selector in this position.Apply the parking brake if the vehicle is sta-tionary with the gear selector in position N.
Drive: position DD is the normal driving position. The car auto-
matically shifts between the various forwardgears, based on the level of acceleration andspeed. The car must be at a standstill whenshifting from position R to position D.
Geartronic: manual shifting (+S–)Geartronic allows you to manually shiftamong your vehicle's forward gears. Gear-tronic can be selected at any time. To shift gears manually, move thegear selector to the side from
D
toward +S–. The +S– symbol in the
instrument panel will change from
white to orange and the number of the gear
currently being used (
1, 2, 3, etc.) will be dis-
played (see the following illustration).
• To return to automatic shifting mode from +S–
, move the gear selector to the side
toward D.

This option indicates when to shift up or down to help conserve fuel. A white arrow willappear above or below the number of thecurrent gear to prompt the driver to shift upor down.
While driving
• If you select the manual shifting position while driving, the gear that was beingused in the Drive position will also initiallybe selected in the manual shifting posi-tion.
• Move the gear selector forward (toward
+)
to shift to a higher gear or rearward(toward –) to shift to a lower gear.
• If you hold the gear selector toward "–",the transmission will downshift one gearat a time and will utilize the braking powerof the engine. If the current speed is toohigh for using a lower gear, the downshiftwill not occur until the speed hasdecreased enough to allow the lower gearto be used.
• If you slow to a very low speed, the trans-mission will automatically shift down.
Shiftlock: Neutral (N)If the gear selector is in the
N position and
the vehicle has been stationary for at least 3 seconds (irrespective of whether the engineis running) then the gear selector is locked. In order to move the gear selector from N to
another gear position, the brake pedal must be depressed and the ignition must be in atleast position II, see page 84.

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.

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.
When the driver releases the accelerator pedal, the transmission is automatically dis-

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
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, seepage 157. In some cases there may be nowarning or the warning may be delayed.The driver should always apply the brakeswhen necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level roads. The system may have difficultymaintaining the correct distance to a vehicleahead on steep inclines, if the vehicle is car-rying a heavy load or is towing a trailer. Inthese situations, the driver should always beprepared to apply the brakes if necessary.

When this symbol has changed col- ors from
white to green , ACC is in
active mode and the vehicle will
maintain the set speed.
This symbol indicates that you are approaching a vehi-cle ahead. ACC will switch from main- taining a set speed to main-
taining a set distance from
that vehicle.
When this happens, a speed range will be indicated on
the speedometer: The higher speed (the cur-
rently set speed (5)) will be marked in green.
The lower speed in the range is the speed of
the vehicle ahead.
Changing the set speed
• After a speed has been set, it can be increased or decreased by briefly press- ing the
or buttons. Each time one
of these buttons is pressed, the vehicle's speed changes by 3 mph(approximately 5 km/h). If the speed isincreased by pressing the accelerator pedal, the vehicle's speed when the but-ton is pressed will be set.
• Press and hold one of the buttons toincrease/decrease the speed by 1 mph(approximately 1 km/h) at a time. Releasethe button when you have reached thedesired speed.
NOTE
•If one of the Adaptive Cruise Control buttons is pressed for more thanapproximately one minute, ACC will bedeactivated. The engine must then beswitched off and restarted to resetACC.
• In some situations Adaptive CruiseControl cannot be put in active mode.
Cruise control Unavailable is shown
in the display, see page 159.
Setting a time intervalThe set time interval to vehicles ahead can be increased by pressing
and decreased by
pressing
. The current time interval is
shown briefly in the display following adjust- ment. Different time intervals canbe selected and are shown in the instrument panel
2
as 1–5
horizontal bars. The greater the number of bars, thelonger the time interval. Onebar represents a time interval
of approximately 1 second; 5 bars is approxi-mately 3 seconds.
To set/change a time interval:
• Press the
/ buttons (3).
At low speeds, when the distance to the vehi- cle ahead is short, ACC increases the timeinterval slightly. In order to follow the vehicleahead as smoothly as possible, ACC allowsthe time interval to vary considerably in cer-tain situations.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driverlimited reaction time if an unexpectedsituation occurs in traffic.
