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 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 25–85 mph (40–140 km/h). Alwaysobserve posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
COASTING will appear in the instrument panel
when Eco Coast is being used.
LimitationsEco Coast is not available if:
• The engine and/or transmission have not reached their normal operating temperature
• Cruise control is activated
• The gear selector is moved from
D to " +/-"
for manual shifting
• The vehicle's speed is not within the25–85 mph (40–140 km/h) range
• The gradient of a down-slope is more thanapproximately 6% •
The steering wheel paddles
* are used for
manual shifting
Deactivating and turning off 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 uti- lize engine braking
• Prior to passing another vehicle, in order todo so as safely as possible
Deactivating Eco Coast (and reactivating engine braking) can be done in the following ways: • Move the gear selector to the manual "

Start/Stop
Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving,for instance in heavy traffic or at a traffic light, tohelp reduce fuel consumption. The engine startsagain automatically when the brake pedal isreleased.
Start/Stop is one of several fuel-conserving fea- tures that also help reduce emissions. This feature helps make it possible to drive more economically by allowing the engine to auto-stopin certain situations.

Using the Start/Stop function Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving,for instance in heavy traffic or at a traffic light, tohelp reduce fuel consumption. The engine startsagain automatically when the brake pedal isreleased.
Start/Stop is available when the engine has been started. The instrument panel will indicate if thefunction is available/unavailable/active. All of the vehicle's normal systems such as light- ing, infotainment, etc., function normally when theengine has auto-stopped. However, certain func-tions, such as climate system blower speed orvery high infotainment system volume, will betemporarily reduced.
Auto-stopThe following conditions must be met for theengine to auto-stop:
• Stop the vehicle by applying the brakes and keep the brake pedal depressed. The engine will auto-stop. If the COMFORT 8
or ECO driv-
ing modes are activated, the engine can auto-stop before the vehicle has come to astandstill.
If the
Adaptive cruise or Pilot Assist functions
are activated, the engine will auto-stop after approx. 3 seconds. See also the article "Condi-tions for Start/Stop."
Auto-startThe following conditions must be met for theengine to auto-start:
• Release the brake pedal; the engine will automatically restart. When starting on anuphill incline, the Hill Start Assist (HSA)function will be activated to help prevent thevehicle from rolling backward.
• When the brake system's Auto Hold functionis activated, the engine will not auto-startuntil the accelerator pedal is pressed.
• When
Adaptive cruise or Pilot Assist are
activated, the engine will auto-start when the accelerator pedal is pressed or if the
button is pressed on the left-side steering wheel keypad.
• Keep the brake pedal depressed but pressthe accelerator pedal. The engine will auto-start.
• On a downhill incline, release the brake pedalso that the vehicle begins to roll. The enginewill auto-start after a slight increase in speed.

the road's incline is very steep.
• the hood is opened.
• the transmission has not reached its normal operating temperature.
• driving at high altitude and the engine hasnot reached its normal operating tempera-ture.
• the gear selector is in the manual shiftingposition.
• the ABS brakes have activated.
• hard braking (even if the ABS brakes havenot activated).
• many starts during a short time period havetriggered the starter motor's overheating pro-tection.
• a trailer's electrical system is connected tothe vehicle's electrical system.
The engine does not auto-startIn certain situations or conditions, the engine may not auto-start
after an auto-stop, such as:
• if the driver is not wearing a seat belt
• the gear selector is in the
P position and the
driver's door is open. The engine must be started normally.
The engine auto-starts while the brake
pedal is depressed
In the following situations, the engine will auto-
start even though the brake pedal is depressed: •
condensation forms on the inside of the win-dows.
• the climate system cannot keep the desiredsettings in the passenger compartment.
• electrical current consumption is temporarilyhigh or the main battery's charge is belowthe minimum level.
• the brake pedal is pumped repeatedly.
• the hood is opened.
• the vehicle begins to move or increasesspeed slightly (if the engine auto-stoppedbefore the vehicle was at a standstill).
• the driver's seat belt is unbuckled while the gear selector is in the
D or N positions.
• the gear selector is moved from
D to R or ±.
• the driver's door is opened with the gearselector in
D: an audible signal and a text
message will inform the driver that the igni- tion is on.
WARNING
Do not open the hood if the engine has auto- stopped. The engine could suddenly auto-start. Before opening the hood:
• Switch off the ignition by turning the start knob in the tunnel console toward
STOP.
• Be aware that if the engine has been run- ning, components in the engine compart-ment will be very hot.

Locating the vehicleThe vehicle's location is shown on a map and directions to the vehicle can be provided. There isalso a digital compass to help show the ownerthe right direction. When you are within approx.100 yards/meters of the vehicle, you can activateits horn and turn signals to help locate it.
The vehicle's instrument panelThis function provides information such as: thefuel level, range on the remaining fuel, averagefuel consumption, average speed and odometer/trip odometer readings.
Vehicle "checkup"The mobile app monitors the vehicle's conditionand provides information about bulbs and the lev-els of brake fluid, coolant and engine oil.
Driving logbookDetailed information about each trip made duringthe past 40 days can be saved and downloaded.All or part of this information can be exportedfrom the mobile app to a spreadsheet format andsent to an email address. This is very useful fore.g., keeping track of business-related driving. This function can be deactivated, in which case the vehicle will not transmit logbook informationat the end of each trip.
Vehicle informationBasic information such as model, license platenumber and VIN number are readily accessible.
Theft notificationIf the vehicle's alarm is triggered, the owner willbe informed via his/her cell phone.
Remote door unlockThe status of all doors and windows is provided.The owner can lock/unlock the vehicle fromanother location but for security reasons, theapp's password is always required before thevehicle can be unlocked.
Engine remote start (ERS)*1ERS makes it possible to remotely start theengine using the remote key to enable the cli-mate system to cool or heat the passenger com-partment before driving. When the engine starts, the climate and infotain- ment systems will restart using the same settingsas when the engine was switched off. You can choose to let the engine run for between 1 and 15 minutes before it automati-cally switches off again. After 2 ERS starts, theengine must be started in the normal way beforeERS can be used again.
WARNING
Keep the following in mind before using ERS:
• The vehicle should be in view.
• The vehicle should be unoccupied.
• The vehicle must not be parked indoors or in an enclosed area. Exhaust fumes areharmful to the health.
NOTE
Always observe applicable state, province and/or local laws regarding engine idlingwhen using ERS.

MAINTENANCE AND SERVICING
498
Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:
Current (V)12
Cold start capacity (Cold Cranking Amperes -CCA) (A)170
Dimensions, L×W×H in. (mm)5.9×3.5×5.1
(150×90×130)
Capacity (Ah)10
• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
• When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa- bled due to high current consumption:
• The engine will auto-start, even if the brake pedal is depressed.
The support battery does not normally required more service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery or a battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery. To help ensure auto-start, the start battery should be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours. If a charger is not available, it is advisable to disable the Start/Stop function until the bat-tery is sufficiently recharged.
