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-

engaged from the engine and engine rpm will be reduced to the idle level(approx. 700-800 rpm), which helps reducefuel consumption. This feature is primarily intended to be used in driving situations where a decrease inspeed is expected, such as when approach-ing an intersection or a traffic light.
Eco Coast enables proactive driving with as little braking as possible.
Combinations of On and OffDepending on the driving situation, Eco can be used in different ways to help reduce fuelconsumption:
• Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for
as far as possible when the driver relea-
ses the accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• Eco deactivated
: engine braking can be
used when the vehicle will only roll for
a short distance (in heavy traffic, etc.) or
when driving down hills .
To help keep fuel consumption as low as possible, Eco Coast should not be used intraffic situations where the brakes have toused frequently.
Activating Eco CoastEco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D
• The vehicle's speed is between approxi- mately 40–85 mph (65–140 km/h). Alwaysobserve posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
Deactivating Eco CoastIn certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to utilize engine braking
• Prior to passing another vehicle, in orderto do so as safely as possible
Deactivating Eco Coast (and reactivating engine braking) can be done in the followingways:
• Press the
ECO button on the center con-
sole
• Move the gear selector to the manual "
S
+/– " position
• Change gears using the steering wheel paddles*
• Press the brake or accelerator pedal
Eco Coast limitationsThis function will not be available if:
• Cruise control is activated
• The gradient of a down-slope is morethan approximately 6%
• The steering wheel paddles* are used tomanually change gears
• The engine and/or transmission have notreached their normal operating tempera-ture
• The gear selector is moved from
D to the
manual " S+/–" position
• The vehicle's speed is not within the40–85 mph (65–140 km/h). interval

Introduction
Start/Stop is a function that is available with certain engines/transmissions. It temporarilyswitches off the engine when the vehicle isnot moving, for instance in heavy traffic or ata traffic light to help reduce fuel consumption.
Function and use
Start/Stop symbol in the instrument panel
Start/Stop button on the center console
Start/Stop is activated automatically each time the engine is started 1
. The symbol in the
instrument panel will be displayed for several seconds when the engine starts and the indi-cator light in the On/Off button will remainilluminated while the function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function of certain systems may reduced atthis time. For example, blower speed andhigh infotainment system volume may bereduced to help conserve the battery'scapacity.
Auto-stopping the engineNormally, when Start/Stop is activated andthe brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically
if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (see page 128) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g.,driving in heavy, stop-and-gotraffic), it may be preferableto deactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the button is pressed again or until the engine isswitched off and restarted by the driver.
Hill Start Assist (HSA)When starting on steep hills, HSA (see page 121) retains pressure on the brake pedalfor several seconds after the pedal has beenreleased in order to keep the vehicle at astandstill. The brakes will be released afterseveral seconds or when the driver pressesthe accelerator pedal.
1 Not when the engine is started using the optional Engine Remote Start feature, see page 118

WARNING
Do not open the hood if the engine has auto-stopped. The engine could suddenlyauto-start. Before opening the hood:
• Switch off the ignition using the START/STOP ENGINE
button.
• Be aware that if the engine has beenrunning, components in the enginecompartment will be very hot.
If the engine does not auto-start, this could be due to

P and the driver's
door is opened
In these cases, the driver will have to restart the engine by pressing the START/STOP
ENGINE button.
Settings
Settings for the Start/Stop function can be made in the MY CAR menu system.Symbols and messages
