Speed-dependent steering force Speed related power steering causes the steer- ing wheel force to increase with the speed of thecar in order to give the driver enhanced sensitiv-ity.
On motorways the steering feels firmer. When parking and at low speed steering is light andrequires only a slight effort.
NOTE
In certain situations the power steering may become too hot and then needs to be tempo-rarily cooled - during this time the powersteering operates with reduced power andturning the steering wheel may then be per-ceived to be slightly heavier. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage.
Change the steering force level *To select the steering force level, go to the "Drive modes" section and see the description at thealternative INDIVIDUAL under the heading"Selectable drive modes". For the car models without a drive mode control with its INDIVIDUAL option, the selection ofsteering force is instead made via the centre dis-play's top view and the following search path:

Roll Stability Control Roll Stability Control (RSC) is a stabiliser sys- tem that minimises the risk of overturning, forexample during sudden evasive manoeuvres or ifthe car skids.
The RSC system registers if and how much the car's lateral inclination changes. This informationis used to calculate the risk of the car overturn-ing. If the car is at risk, its electronic stability con-trol system engages, the engine torque isreduced and one or more wheels are braked untilthe car has regained its stability.
WARNING
Under normal driving conditions, the RSC sys- tem improves the car's road safety, but thismust not be taken as a reason to increasespeed. Always follow the normal precautionsfor safe driving.

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.

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.
17 See the section "Drive mode ECO".
18 Applies to driving with manual gear changing.

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.
