With automatic gearbox
• Stop the car with the foot brake and then keep your foot on the brake pedal - theengine stops automatically.
With manual gearbox
• Declutch, set the gear lever in neutral posi-tion and release the clutch pedal - theengine stops automatically.
In drive mode
Eco or Comfort3 , the engine may
auto-stop before the car is completely stationary. With the
Adaptive cruise or Pilot Assist func-
tion activated, the engine will autostop after approximately three seconds. See the section "Conditions for Start/Stop func- tion".
AutostartThe following is required for the engine to auto-start: With automatic gearbox
• Release the brake pedal - the engine will autostart and you can continue driving. On anuphill gradient hill start assist (HSA) engages, which prevents the car from rollingbackwards.
• When the
Auto hold function is activated,
auto-start is delayed until the accelerator pedal is depressed.
• When the
Adaptive cruise or Pilot Assistfunction are activated, the engine will autos- tart when the accelerator pedal is depressed, or by pressing the
button on the left
keypad of the steering wheel.
• Maintain foot pressure on the brake pedal and depress the accelerator pedal - theengine auto-starts.
• On a downhill gradient: Release pressure onthe brake pedal slightly so that the carbegins to roll - the engine will auto-start aftera slight speed increase.
With manual gearbox
• With the gear lever in neutral position:Depress the clutch pedal or depress theaccelerator pedal - the engine starts.
• On a downhill gradient: Release pressure onthe brake pedal slightly so that the carbegins to roll - the engine will auto-start aftera slight speed increase.

Selectable drive modes
COMFORT
•
This is the car's normal mode.
When the car starts, it is in
Comfort mode and
the Start/Stop function is activated. These set- tings mean that the car feels comfortable, thesteering is light, the shock absorption is soft andbody's movement is smooth. This drive mode is the certification mode for car- bon dioxide emissions.
ECO
• Adapt the car for more energy-efficient and environmentally-conscious driving with the
Eco mode.
The drive mode means, for example, that the Start/Stop function is activated and the output ofcertain climate settings is reduced. The driver display has an ECO gauge that facili- tates fuel-efficient driving. More information on this drive mode is found in the section "Drive mode ECO".
DYNAMIC
•Dynamic mode means that the car has
sportier characteristics and faster response to accelerating.
The gear changes become faster and more dis-tinct, and the gearbox prioritises a gear withgreater traction. Steering response is faster and shock absorption is harder 6
which means that the body follows the
roadway in order to reduce roll during cornering. Start/Stop function is deactivated.
INDIVIDUAL
• Adapting a drive mode according to individ- ual preferences.
Select a drive mode to start from, and then adjustthe settings according to the desired driving cha-racteristics. These settings are saved in an indi-vidual driver profile. An individual drive mode is only available if it is first activated in the centre display.

Drive mode ECO
Driving mode ECO mode optimises the car's
driving characteristics for more fuel efficient and environmentally-conscious driving.
Use this drive mode to save fuel and the environ- ment. The following properties are adapted for Eco driv- ing:
• Gearbox gearshift points 8
.
• Engine management and response from theaccelerator pedal.
• The Eco Coast 9
freewheel function is acti-
vated and engine braking is deactivatedwhen the accelerator pedal is released atspeeds between 65 and 140 km/h(40 and 87 mph).
• Some of the climate control system's set-tings work at reduced power or are deacti-vated.
• The driver display shows information in anECO gauge which facilitates environmentally-conscious and fuel-efficient driving.
Selecting ECO modeThe Eco mode is deactivated when the engine isswitched off, and it must therefore be activatedafter each time the engine is started. The driver display shows ECO when the function is acti-vated.

In the centre display's function view
A car without drive mode con- trol has a function button for
Driving mode ECO in the
centre display's function view.
–Press the button in order to activate the function.
> An indicator in the button illuminates when the function is activated.
Freewheel function Eco Coast 10The freewheel function Eco Coast means in prac- tice that engine braking ceases, meaning in turnthat the car's kinetic energy is used to freewheelfor longer distances. When the driver releasesthe accelerator pedal the gearbox is automaticallydisengaged from the engine whose speed isreduced to idling speed with reduced consump-tion. The function is best used where it is possible to freewheel a long way, e.g. roads with a slightdownhill gradient or when there is a predictablespeed reduction to freewheel into a zone with alower speed limit.
Activating the freewheel function
The function is activated when the accelerator pedal is fully released, in combination with thefollowing parameters:
• Drive mode
Eco is activated.
• The gear selector is in
D position.
• Speed within the range of approx. 65-140 km/h (40-87 mph).
• The road's downhill gradient is not steeperthan approx. 6%.
The driver display shows
COASTING when the
freewheel function is being used.
Limitations
The freewheel function is not available if:
• Engine and/or gearbox are not at normal operating temperature.
• The cruise control is activated.
• The gear selector is moved from the
D posi-
tion and the manual position.
• The speed is outside the range ofapprox. 65-140 km/h (40-87 mph).
• The road's downhill gradient is steeper thanapprox. 6%.
• Manual gear changing is performed with the steering wheel paddles
*.
Deactivating and switching off the freewheel function
In certain situations it may be desirable to deacti- vate or switch off the function in order to useengine braking. Examples of such situations maybe on steep downhill gradients or before animminent overtaking manoeuvre - in order to beable to do it in the safest way possible. Deactivate the freewheel function as follows:
• Actuate the accelerator or brake pedal.
• Move the gear selector to manual position.
• Changing gear with steering wheel paddles
*.
Switch off the freewheel function as follows:
• Change drive mode
*, or switch off the
Driving mode ECO in the function view.
Even without the freewheel function, it is possible to freewheel for short distances. This, in turn,reduces consumption. However, for the best fueleconomy it is better to have the freewheel func-tion activated and be able to freewheel for longerdistances.
ECO gauge in the driver displayThe ECO gauge indicates how fuel-efficient thedriving is:

With fuel-efficient driving, the gauge shows a low value with the pointer in the green zone.
• With non-fuel-efficient driving, e.g. duringheavy braking or heavy acceleration, thegauge shows a high value.
The ECO gauge also has an indicator to showhow a reference driver would drive the car underthe same driving conditions. This is indicated withthe short pointer on the gauge.
Eco gauge in the 12-inch driver display.
Eco gauge in the 8-inch driver display.
ECO climate controlIn the Eco drive mode, ECO climate control is
activated automatically in the passenger com- partment in order to reduce energy consumption.
NOTE
When the ECO function is activated, several parameters in the climate control system'ssettings are changed, and several electricityconsumer functions are reduced. Certain set-tings can be reset manually, but full function-ality is only regained by switching off the ECO function or adapting
Individual* drive mode
with full climate functionality.

Overloading the starter battery
The electrical functions in the car load the starter battery to varying degrees. Avoid using the igni-tion position II when the car is switched off.
Instead, use ignition position I - which uses less
power.
Also, be aware of different accessories that load the electrical system. Do not use functions whichuse a lot of power when the car is switched off.Examples of such functions are:
• ventilation fan
• headlamps
• windscreen wiper
• audio system (high volume).
If the starter battery voltage is low, the message
12 V Battery Low charge, will soon enter
power save mode is shown in the driver display.
The energy-saving function then shuts down cer- tain functions or reduces certain functions suchas the ventilation fan and/or audio system.
–In which case, charge the starter battery by starting the car and then running it for atleast 15 minutes - starter battery charging ismore effective during driving than runningthe engine at idling speed while stationary.

Preparations for a long trip
Before a driving holiday or some other type of long journey, it is important to check the car'sfunctions and equipment particularly carefully.
Check that:
• the engine is working normally and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• all bulbs are working
• the tyres have sufficient tread depth andpressure
• a warning triangle and high-visibility vest arelocated in the car - legally required in certaincountries
• the wiper blades are in good condition.

Economical driving
Drive economically and eco-consciously by driv- ing smoothly, thinking ahead, and adjusting yourdriving style and speed to the prevailing condi-tions.
• For lower fuel consumption, activate ECO drive mode.
• Use the Eco Coast 17
freewheel function -
engine braking will cease and the car'skinetic energy can be used to freewheel forlonger distances.
• Drive in the highest gear 18
possible, adapted
to the current traffic situation and road -lower engine speeds result in lower fuel con-sumption. Use the gear shift indicator.
• Drive at a steady speed and keep a good dis-tance to other vehicles and objects to mini-mise braking.
• High speed results in increased fuel con-sumption - the wind resistance increaseswith speed.
• Do not run the engine to operating tempera-ture at idling speed, but rather drive with anormal load right after starting - a coldengine consumes more fuel than a warmone. •
Drive with the correct air pressure in thetyres and check this regularly - select ECOtyre pressure for best results.
• Choice of tyres can affect fuel consumption -seek advice on suitable tyres from a dealer.
• Remove unnecessary items from the car -the greater the load the higher the consump-tion.
• Use engine braking to slow down, when itcan take place without risk to other roadusers.
• A roof load and space box increase windresistance, leading to higher consumption -remove the load carriers when not in use.
• Avoid driving with open windows.
WARNING
Never switch off the engine while moving, such as downhill, this deactivates importantsystems such as the power steering andbrake servo.

Towing bracket
*
The car can be equipped with a towing bracket that makes it possible to tow e.g. a trailer afterthe car.
There may be different towing bracket variants available for the car; contact a Volvo dealer formore information. For information on towing capacity and towball load, see the section "Towing capacity and tow-ball load".
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
IMPORTANT
The towball needs regular cleaning and lubri- cation with grease in order to prevent wear.
