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 9
. The symbol in the instru-
ment panel will be displayed for several seconds when the engine starts and the indicator light inthe On/Off button will remain illuminated whilethe function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function ofcertain systems may reduced at this time. Forexample, blower speed and high infotainmentsystem volume may be reduced to help conservethe battery's capacity.
Auto-stopping the engine
Normally, when Start/Stop is activated and the brakes are applied until the vehicle comes to a standstill, the engine will auto-stop automatically if the driver keeps the brake pedal depressed
.
To remind the driver that the enginehas been auto-stopped, the Start/Stopsymbol will illuminate in the instrumentpanel and remain on until the engine
restarts.
If the ECO function * is acti-
vated, the engine may auto- stop before the vehicle comesto a complete standstill.
Auto-starting the engine
The engine restarts as soon as the driver relea- ses the brake pedal.
Deactivating Start/Stop
In certain situations (e.g., driv- ing in heavy, stop-and-go traf-fic), it may be preferable todeactivate 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 but- ton is pressed again or until the engine isswitched off and restarted by the driver.

ECO*
Eco is a function 10
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuel consump-tion.
IntroductionWhen Eco is activated, the fol- lowing functions are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Stop/stop function (Start/Stop – introduction(p. 268)): the engine can auto-stop beforethe vehicle has come to a full stop
• Eco Coast functionality is activated: enginebraking 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 the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Function
ECO On/Off button in the center console
ECO symbol in the instrument panel
When the engine is switched off, ECO is deacti- vated and must be reactivated each time theengine is started (with the exception of certainengines). The
ECO symbol will be displayed in the instru-
ment panel and the indicator light in the ECO
button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, theECO symbol will not be dis-
played in the instrument panel and the indicator light in the ECO button will be off. The
function will remain deactivated until the button is pressedagain.
Eco CoastEco Coast is an integral part of the Eco function and essentially deactivates engine braking, allow-ing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should pri- marily be used when the vehicle can coast asfar as possible.
When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine and engine rpm will be reducedto the idle level (approx. 700-800 rpm), whichhelps reduce fuel consumption.

STARTING AND DRIVING
* Option/accessory, for more information, see Introduction.
274 This feature is primarily intended to be used in driving situations where a decrease in speed isexpected, such as when entering a zone with alower speed limit. Eco Coast enables proactive driving with as little braking as possible.
Combinations of On and Off
Depending on the driving situation, Eco can be used in different ways to help reduce fuel con-sumption:
• With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching atraffic light or intersection).
or
• With 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 possi-ble, Eco Coast should not be used in traffic situa-tions where the brakes have to be used fre-quently.
Activating Eco Coast
Eco 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 Coast
In certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to uti-lize engine braking
• Prior to passing another vehicle, in order todo so as safely as possible
Deactivating Eco Coast (and reactivating enginebraking) can be done in the following ways: • Press the
ECO button on the center console
• Move the gear selector to the manual "
S+/–"
position
• Change gears using the steering wheel pad- dles
*
• 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 more than approximately 6%
• The steering wheel paddles
* are used to
manually change gears •
The engine and/or transmission have notreached their normal operating temperature
• 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
Additional information and settings
Other ECO-related settings can be made in the vehicle's
MY CAR menu. See My Car – introduc-
tion (p. 77) for more information.

STARTING AND DRIVING
275
All Wheel Drive (AWD)Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distrib-uted automatically between the front and rearwheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in the AWD system. A warning light will also illu-minate in the instrument panel. If this occurs,have the system checked by a trained andqualified Volvo service technician.

Hill Descent Control (HDC) – introduction
HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients using onlythe accelerator pedal, without applying thebrakes. The brake system functions automaticallyto maintain a low and steady speed.
IntroductionNormally, when the accelerator pedal is released while driving down hills, the vehicle's speed slowsas the engine runs at lower rpm (the normalengine braking effect). However, if the downhillgradient becomes steeper and if the vehicle iscarrying a load, speed increases despite theengine braking effect. In this situation, the brakesmust be applied to reduce the vehicle's speed. HDC is particularly useful when driving down steep hills with rough surfaces, and where theroad may have slippery patches.
WARNING
HDC does not function in all situations, and is a supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.

Hill Descent Control (HDC) – operation
Function
•HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDC isactivated.
• The indicator light
in the instrument
panel illuminates and a message is displayed when the system is controlling the vehicle'sspeed.
• HDC only functions when
first or reverse
gears are selected (
1 will be shown in the
instrument panel display when first gear is selected).
NOTE
HDC cannot be activated if the gear selector is the D position.
Using HDCHDC allows the car to roll forward at a maximum speed of 6 mph (10 km/h), and 4 mph (7 km/h)in reverse. However, the accelerator pedal can beused to select any speed that is possible in firstor reverse gears. When the accelerator pedal isreleased, speed is quickly reduced again to6 mph (10 km/h) or 4 mph (7 km/h), dependingon the gear selected, regardless of the hill's gra-dient. It is not necessary to apply the brakes.
• The brake lights illuminate automaticallywhen HDC is controlling the vehicle's speed.
• The driver can slow or stop the vehicle at anytime by applying the brakes.
HDC is deactivated when:
• The button on the center console is pressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an automatic
transmission
HDC can be deactivated at any time. If this isdone while driving down a steep hill, the system'sbraking effect will decrease gradually.
NOTE
Engine response to pressure on the accelera- tor pedal may be slightly slower than normalwhen HDC is activated.
