Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.

Recovery
This section refers to transporting the vehicle with a tow truck or similar vehicle.
Call a professional towing service for assistance. In certain conditions, the towing eyelet can be used to pull the vehicle onto a flatbed tow truck. For vehicles equipped with leveling control *:
If the vehicle is equipped with pneumatic suspen- sion, this feature must be turned off before thevehicle is lifted onto a tow truck. Turning off thefunction in the center display. 1. Tap
Settings in the Top view.
2. Tap
My CarParking Brake and
Suspension.
3. Select
Disable Leveling Control.
The vehicle's location and ground clearance determine if it can be lifted onto a tow truck. Ifthe incline of the tow truck is too steep or if theground clearance under the vehicle is insufficient,attempting to pull it up may result in damage. Inthis case, the vehicle should only be lifted withthe tow truck's lifting equipment.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted onto the bedof the truck.
CAUTION
The towing eyelet is only intended for towing on roads, and must not be used to pull vehi-
cles from ditches or any similar purpose involving severe strain. Call a tow truck forprofessional assistance.
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.

CAUTION
Snow chains can be used on the vehicle, with the following restrictions:• Volvo recommends not using snowchains on wheel dimensions larger than18 inches.
• Always follow the manufacturer's installa-tion instructions carefully. Install chainsas tightly as possible and retighten peri-odically.
• Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, suspen-sion and body components must bemaintained.
• Check local regulations regarding the useof snow chains before installing.
• Never exceed the snow chain manufac-turer's specified maximum speed limit.Under no circumstances should youexceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• Avoid driving on surfaces without snow as this wears out both the snow chains andthe tires.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
• Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

Tire sealing system12
The temporary tire sealing system can be used to seal a puncture in a tire or to check andadjust the pressure in the tire. Models equipped with a spare wheel 13
do not
have the tire sealing system.
The tire sealing system consists of a compressor and a bottle containing sealing compound. Thesealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but may not beable to fully seal tires with punctures in thesidewall. Do not use the tire sealing systemon tires with large tears, cracks or similardamage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the trunk.

LOADING, STORAGE AND PASSENGER COMPARTMENT
}}
* Option/accessory.543
Cargo compartment Loads can be secured in the trunk to keep them in place while driving.
The folding* rear seat backrests can help
increase the cargo capacity of the trunk. Load anchoring eyelets and grocery bag holders areprovided to help secure objects in place. The towing eyelet and tire sealing system, or the temporary spare tire *, are located under the
cargo compartment floor.
Related information
• Loading recommendations (p. 543)
• Grocery bag holders (p. 544)
• Load anchoring eyelets (p. 545)
Loading recommendations
There are a number of things to consider when carrying loads in or on the vehicle.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories reduces thevehicle's load-carrying capacity by the corres-ponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position of theload.
Loading in the trunk and cargo compartment
• Position objects so they are pressing against the rear seat backrests.
• Distribute the load evenly.
• Heavy objects should be positioned as lowas possible. Avoid placing heavy objects onfolded-down seat backrests.
• Cover sharp corners with a soft cloth or simi-lar to help prevent damage to the upholstery.
• Use the load anchoring eyelets and tension-ing straps or similar to secure all objects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured object weighing 20kg (44 pounds) can reach a projectile weightequivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm (4in.) space between the objects and the win-dow. Objects placed closer to this couldimpede the function of the inflatable curtainconcealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure people in thevehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading long objects.Otherwise, it is possible for the load to reachthe gear lever or gear selector and move it toa drive position – which could cause the vehi-cle to begin rolling.

Data transfer between vehicle andworkshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net- work for secure data transfer between your vehi-cle and the workshop. Your visit to the workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your technician can connect your vehicle to the workshop's Wi-Finetwork to perform troubleshooting and down-load software. For this type of communication,the vehicle only connects to the workshop's net-work. The vehicle can only be connected to thedesignated workshop networks, not to any othernetwork, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by aservice technician. Because the technician usesthe buttons on your remote key to connect thevehicle, it is important that you bring a key withbuttons when taking the vehicle in to a workshop.Pressing the lock button on the remote key threetimes will connect the vehicle to the workshop'sWi-Fi network. When the car is connected to a Wi-Fi network, the
symbol appears in the center display.
WARNING
The vehicle may not be driven when it is con- nected to the workshop's networks and sys-tems.
