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. 262)): 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.
10 Option on models equipped with certain 4-cylinder engines

STARTING AND DRIVING
* Option/accessory, for more information, see Introduction.
268 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. 71) for more information.

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.
Related information
• Transmission – general information (p. 256)
Brakes – general The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault has occurred. If this light comes on while driving or braking, stop immediately and check the brake fluid levelin the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the
MIN mark in the
reservoir or if a brake system message is shown in the information display: DO NOT
DRIVE . Have the vehicle towed to a trained
and qualified Volvo service technician and have the brake system inspected.

Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising the vehicle (see Changing a wheel – removing wheel(p. 295) for information about using the jack andremoving a wheel) and performing a visualinspection of the brake pads.
WARNING
• If the vehicle has been driven immediately prior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
WARNING
• Use the jack intended for the vehicle when changing a tire. For any other job,use stands to support the vehicle.
• The jack should be kept well-greased andclean, and should not be damaged.
• Be sure the jack is on a firm, level, non-slippery surface.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
• The jack must correctly engage the jackattachment.
• Never allow any part of your body to beextended under a vehicle supported by ajack.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Neverlet the vehicle roll to a stop with the engineswitched off. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels harderthan usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.
