WHEELS AND TIRES

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 cargo compartment.

LOADING, STORAGE AND PASSENGER COMPARTMENT
}}
* Option/accessory.555
Cargo compartment The vehicle has a flexible cargo compartment that makes it possible to carry and secure largeobjects.
The cargo capacity of the vehicle can be consid- erably increased by folding down the rear seatbackrests. Use the load anchoring eyelets or gro-cery bag holders to help secure objects in place, and the retractable cargo compartment cover * to
help conceal objects in the cargo compartment. The towing eyelet and tire sealing system, or the temporary spare tire *, are located under the
cargo compartment floor.

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.

Support battery In addition to the start battery, vehicles equipped with the Start/Stop function also have a supportbattery.
Vehicles with the Start/Stop function are equip- ped with two 12-volt batteries ‒ a heavy-duty
start battery and a support battery that provides extra current during the Start/Stop function'sstart sequence.
The support battery is located in a box next to the spring strut in the engine compartment.
NOTE
• The higher the current consumption in the vehicle, the more the alternator has towork and the batteries have to becharged = increased fuel consumption.
• When the starter battery capacity hasdropped below the lowest permissiblelevel, the Start/Stop function is disen-gaged.
When the Start/Stop function is temporarily reduced due to high current consumption:
• The engine will auto-start, even if the driverdoes not lift their foot from the brake pedal.
The support battery does not normally requiremore service than the start battery. If you have any questions or concerns, consult a workshop ‒
an authorized Volvo workshop is recommended.
CAUTION
If the following is not observed, the Start/ Stop function may temporarily stop workingafter connection of an external starter batteryor battery charger: • The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.

Cleaning leather upholstery
Only use cleaning agents and car care products recommended by Volvo. Clean regularly andtreat stains immediately for best results. It isimportant to vacuum before using a cleaningagent.
Leather upholstery *Volvo's leather upholstery is treated to protect its original appearance. Over time, sunlight, grease,dirt, etc. could break down the protective layer.This could result in scratches and cracking. Leather upholstery is a natural product that changes and acquires a beautiful patina overtime. Regular cleaning and treatments arerequired to preserve the qualities and color of theleather. Volvo offers a comprehensive product,Volvo Leather Care Kit/Wipes, for cleaning andtreating leather upholstery that, when used asdirected, preserves the leather's protective coa-ting. For best results, Volvo recommends cleaning and applying protective cream one to four times ayear (or more as needed). Volvo Leather Care Kit951 0251 and Volvo Leather Softener 9437429 are available for purchase at Volvo retailers.
