WARNING
Do not press the extend/retract button if a trailer is attached to the towing bracket.
NOTE
The towbar must finish the extension proce- dure before it can then be moved to lockedposition. This procedure may take severalseconds. If the towbar is not fixed in lockedposition, wait a few seconds and try again.
3. Move the towbar to its end position, where it is secured and locked in place - the indicator lamp illuminates with a constant orangeglow.
> The towbar is ready for use.
WARNING
Take care to secure the trailer's safety cable in the intended bracket.
NOTE
Power save mode activates after a while and the indicator lamp goes out. The system isreactivated by closing and opening the tail-gate. This applies when retracting or extend-ing the towing bracket. If the car detects a connected trailer electri- cally, the indicator lamp stops illuminatingwith a constant glow.
Retracting the towing hitch
IMPORTANT
Make sure that there is no plug or adapter in the electrical socket when retracting the tow-ing bracket.
1. Open the tailgate. Press and release the but- ton on the right-hand side at the rear of the cargo area - retraction might not start if thebutton is pressed for too long.

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.

Towing eye
Use the towing eye for towing. The towing eye is screwed into a threaded socket behind a coveron the right-hand side of the bumper, front orrear.
NOTE
If the car is equipped with a towing bracket, there is no rear mounting for a towing eye.
Fitting the towing eye
Take out the towing eye from the foam block under the floor hatch in the cargo area.
Front: Remove the cover.
> The cover pivots around its centre line and can then be removed.Rear: Remove the cover - press on the mark- ing with a finger and, at the same time, foldout the opposite side/corner using a coin orsimilar.
> The cover pivots around its centre line andcan then be removed.
4. Screw the towing eye right in until it stops. Tighten the towing eye firmly e.g. using the wheel wrench *.
After use, unscrew the towing eye and return it to its place. Finish by refitting the cover onto the bumper.
IMPORTANT
It is important that the towing eye is firmly screwed into place - right in until it stops.

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.

General information on the tyre monitoring system
In the information below, the tyre monitoring sys- tem is referred to generically as TPMS. Each tyre, including the spare tyre *, should be
checked once a month. When checking, the tyre should be cold and have the air pressure recom-mended by the car manufacturer specified on thetyre pressure label or in the tyre pressure table. Ifthe car has tyres of a different size than that rec-ommended by the manufacturer, find out whatthe correct air pressure level is for these. As an extra safety feature, the car is equipped with a tyre pressure monitoring system (TPMS),which shows when the air pressure in one ormore tyres is too low. When the indicator symbolfor low air pressure is lit, stop and check the tyresas soon as possible and inflate to the correct airpressure. Driving with tyres that have tyre pressure that is too low may cause the tyre to overheat, whichcan cause a puncture. Low tyre pressure alsoreduces fuel efficiency as well as tyre service life,and can affect car handling and stopping ability.Note that TPMS does not replace regular tyremaintenance. It is the driver's responsibility tomaintain correct tyre pressure, even if the limit forlow tyre pressure has not been reached so thatthe indicator symbol illuminates. The car is also equipped with a TPMS system fault indicator, which indicates when the system is not functioning correctly. The TPMS systemfault indicator is combined with the indicator sym-bol for low tyre pressure. When the systemdetects a fault, the symbol in the driver displaywill flash for about one minute and then remainilluminated. This procedure will be repeated whenthe car is started until the fault has been rectified.When the symbol is illuminated, the system's abil-ity to detect or warn of low tyre pressure may beaffected. A TPMS system fault can occur for several rea- sons, such as after changing to a spare tyre, orchanging tyres or wheels that prevent TPMS fromfunctioning correctly. Always check the indicator symbol for TPMS after changing one or more tyres in order toensure the new tyre or wheel is working correctlywith TPMS.
Messages in the driver displayThe following messages may be shown when theindicator symbol is illuminated:
•
Tyre pressure low Check tyres, calibrate
after fill
•Tyre pressure system Temporarily
unavailable
•Tyre pressure system Service required.
If the system cannot determine which tyre has low pressure, all four tyres will be indicated in thecentre display.
To bear in mind
• Always calibrate the system after a wheelchange or tyre pressure adjustment. See thetyre pressure label on the driver's side doorpillar for Volvo's recommended tyre pres-sures.
• The system does not replace normal tyremaintenance.
• There is no option to deactivate ITPMS.

Calibrating tyre monitoring *
In order for the Indirect Tyre Pressure Monitoring System (ITPMS) to work correctly, a referencevalue for the tyre pressure must be determined.This must be performed each time the tyres arechanged or the tyre pressure is changed.
For example, when driving with a heavy load or at high speed above 160 km/h (100 mph), the tyrepressure should be adjusted in accordance withVolvo's recommended tyre pressure values. Fol-lowing which, the system must be recalibrated.
1. Stop the engine.
2. Inflate the tyres to the desired pressure in accordance with the tyre pressure label on the door pillar on the driver's side.
3. Start the engine. 4.
Open the
Car status app in the app view.
5.Tap on Status to view tyre monitoring.
NOTE
The car must be stationary when calibration is started.
6.Press Calibrate.
7. Tap on
OK to confirm that the tyre pressure
in all four tyres has been checked and adjusted. 8. Drive the car.
Calibration is performed while the car is driv-ing. Calibration is interrupted temporarily ifthe engine is switched off, but is resumedautomatically when the car is driven again.
> When sufficient data has been collectedto enable the system to detect low tyre pressure, the tyres in the centre displaychange colour from grey to green. Thesystem provides no additional confirma-tion that the calibration is complete. If calibration fails, a message is shown:
Calibration unsuccessful. Please try again..
NOTE
Remember that the TPMS system must be recalibrated at each tyre change or if the tyrepressure is adjusted. New reference valuesmust be stored for the system to work cor-rectly.

Data transmission between car and workshop6
The time required for a booked visit to a Volvo workshop can be shortened by transmitting trou-bleshooting data as soon as the car stops at theworkshop. The data can be transmitted most conveniently by selecting the option
Automatically connect
when I arrive in settings view in the centre dis-
play.
Each time the car slows to a slow enough speed it starts searching for a Wi-Fi network. If anauthorised Volvo network (at a workshop) isfound, a message is displayed or a pop-up win-dow opens in the centre display. (This does notapply when you connect manually, see the sec-tion "Connecting to a workshop manually"below).
Connecting to a workshop automatically
NOTE
To avoid the driver being disturbed by unwan- ted connection inquiries (for example, if thecar is often parked in the neighbourhood of aworkshop with an authorised Volvo network),the connection mode will change to manual ifthe driver declines connection twice within aperiod of 5 days.
Without driver confirmation
This option provides the most convenient way of transmitting troubleshooting data. The car con-nects without the need for the driver to confirm. If the car stops at the workshop and is switched off with the start knob, a message is shown atthe top in the centre display. The car will connectautomatically when the driver
