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.

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.

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.

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. 303) 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.

Anti-lock braking system (ABS) The ABS system helps to improve vehicle con- trol (stopping and steering) during severe brak-ing conditions by limiting brake lockup.
When the system "senses" impending lockup, braking pressure is automatically modulated inorder to help prevent lockup that could lead to askid. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.

Brake lights The brake lights come on automatically when the brakes are applied.
Adaptive brake lights
The adaptive brake lights activate in the event of sudden braking or if the ABS system is activated.This function causes an additional taillight oneach side of the vehicle to illuminate to help alertvehicles traveling behind. The adaptive brake lights activate if:
• The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds above approxi-mately 6 mph (10 km/h).
When the vehicle has come to a stop, the brakelights and additional taillights remain on for aslong as the brake pedal is depressed or untilbraking force on the vehicle is reduced.

Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect immediately in the event of sudden, hard brak-ing.
Emergency Brake AssistanceThe EBA system is activated by the speed with which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brake sys-tem immediately increases to the maximum level.Maintain full pressure on the brake pedal in orderto utilize the system completely. EBA is automati-cally deactivated when the brake pedal isreleased.

NOTE
•When the EBA system is activated, the brake pedal will go down and pressure inthe brake system immediately increasesto the maximum level. You must maintainfull pressure on the brake pedal in orderto utilize the system completely. Therewill be no braking effect if the pedal isreleased. EBA is automatically deacti-vated when the brake pedal is released.
• When the vehicle has been parked forsome time, the brake pedal may sinkmore than usual when the engine isstarted. This is normal and the pedal willreturn to its usual position when it isreleased.
