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.

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:

Brake functions
The car's brakes are used to reduce the speed or prevent the car from rolling.
Besides the foot brake and parking brake, the car is equipped with several automatic brake assistfunctions. These can assist the driver by notneeding to keep his/her foot on the brake pedalwhen stationary at a traffic light, when starting onan uphill gradient or when driving on a downhillgradient. Depending on the car's equipment, the following auto braking functions are available:
• Automatic braking when stationary (AutoHold)
• Hill start assist (Hill Start Assist)
• Auto braking after a collision
• City Safety

Foot brake
The foot brake is used to reduce the car's speed while driving.
Foot brake systemThe car is equipped with two brake circuits. If a brake circuit is damaged, the brake pedal willengage deeper. Higher pressure on the pedal willtherefore be needed to produce the normal brak-ing effect. The driver's brake pedal pressure is assisted by a brake servo.
WARNING
The brake servo only works when the engine is running.
If the foot brake is used when the engine is switched off then the pedal will feel stiff and ahigher pedal pressure must be used to brake thecar. In very hilly terrain or when driving with a heavy load the brakes can be relieved by using enginebraking in manual gearshift mode. Engine brakingis most efficiently used if the same gear is useddownhill as up.
Anti-lock braking systemThe car has anti-lock brakes, Anti-lock BrakingSystem (ABS), which prevent the wheels fromlocking while braking and allows maintained steering control. Vibration may be felt in thebrake pedal when this is engaged and this is nor-mal. A short test of the ABS system is made automat- ically after the engine has been started when thedriver releases the brake pedal. A further auto-matic test of the system may be made at lowspeed. The test may be experienced as pulses inthe brake pedal.
Braking on wet roadsWhen driving for a prolonged period of time inheavy rain without braking, the braking effect maybe delayed slightly when next using the brakes.This may also be the case after a car wash. It isthen necessary to depress the brake pedal moreforcefully. You should therefore maintain agreater distance to the vehicles in front. Brake the car firmly after driving on wet roads or using a car wash. This warms up the brake discs,enabling them to dry faster and protecting themagainst corrosion. Bear in mind the current trafficsituation when braking.
Braking on salted roadsWhen driving on salted roads, a layer of salt mayform on the brake discs and brake linings. Thismay extend braking distance. You should there-fore maintain an extra large safety distance tovehicles in front. In addition, make sure you dothe following:

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.

snaking. The function is included in the stability system ESC19
.
Reasons for snakingThe snaking phenomenon can occur with any car/trailer combination. Snaking normally occursat high speeds. But, there is a risk of it occurringat lower speeds if the trailer is overloaded or theload is improperly distributed, e.g. too far back. In order for snaking to occur, there must be a triggering factor, e.g.: • Car with trailer subjected to a sudden and powerful side wind.
• Car with trailer drives on an uneven road sur-face or in a pothole.
• Sweeping steering wheel movements.
If snaking has started, it could be difficult or evenimpossible to suppress. This makes the car/trailer combination difficult to control and there isa risk that you could, for example, end up in thewrong lane or leave the carriageway.
Trailer Stability Assist functionThe trailer stability assist function continuallymonitors car movements, particularly lateralmovements. If snaking is detected, the frontwheels are individually braked. This serves to sta-bilise the car/trailer combination. This is oftenenough to help the driver regain control of thecar. If snaking is not eliminated the first time thattrailer stability assist comes into action, the car/trailer combination is braked with all wheels andengine power is reduced. Once snaking has beengradually suppressed and the car/trailer combi-nation is stable once again, the system stopsregulating and the driver once again has full con-trol of the car.
NOTE
The stability function is deactivated if the driver selects Sport mode by deactivating
ESC via the menu system in the centre dis-
play.
The trailer stability assist may fail to engage if the driver uses severe steering wheel movements totry to rectify the snaking because in such a situa-tion the system cannot determine whether it isthe trailer or the driver that is causing the snak-ing.
When trailer stability assist is operating, the ESC symbol
flashes in the driver display.

The towing eye may be used to pull the car up onto a recovery vehicle with a flatbed platform.The car's position and ground clearance deter-mine whether it is possible. If the slope of the recovery vehicle's ramp is too steep, or if the ground clearance under the car isinadequate, then the car may be damaged if youtry to pull it up using the towing eye. If necessary, raise the car by using the recovery vehicle's lifting device. Do not use the towing eye.
WARNING
No one/nothing is allowed to remain behind the recovery vehicle while the car pulled uponto the flatbed platform.
IMPORTANT
The towing eye is only designed for towing on roads -
not for pulling the car unstuck or out
of a ditch. Call a recovery service for recovery assistance.

Towing
During towing, one vehicle pulls another vehicle along behind it by means of a towline.
Find out the statutory maximum speed limit for towing before the towing begins.
Preparations and towing1. Activate the car's hazard warning flashers.
2. Secure the towline in the towing eye.
3. Deactivate the steering lock by unlocking the car.
NOTE
In ignition position II the steering lock is
deactivated if the car has been unlocked. See section “Ignition position” for more informa-tion.
4. Set the car in ignition position II by turning
the ignition dial to START and holding the
ignition dial in the START position for
approx. 4 seconds. Then release the knob, which automatically returns to its startingposition.
5. Move the gear selector to neutral position N
and release the parking brake.
> The towing vehicle can now start towing. 6. Keep the towline taut when the towing vehi-
cle reduces speed by holding your foot gen- tly pressed on the brake pedal - therebyavoiding unnecessary jerking.
7. Be prepared to brake to stop.
IMPORTANT
Note that the car must always be towed with the wheels rolling forward. • Do not tow cars with automatic transmis- sion at speeds higher than 80 km/h(50 mph) or for distances in excess of 80km.
WARNING
•Check that the steering lock is unlocked before towing.
• Ignition position
II must be active - in
ignition position I all airbags are deacti-
vated.
• Always keep the remote control key in thecar when it is being towed.
WARNING
The brake servo and power steering do not work when the engine is switched off - thebrake pedal needs to be depressedabout 5 times more heavily and the steering isconsiderably heavier than normal.
