Using the electrical outlets
The 12 V outlet can be used for devices intended for this such as MP3 players, cool-ers and cellular phones.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be active as long as there is sufficient chargein the start battery. If the engine is turned off and the vehicle is locked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for upto 7 minutes.
NOTE
Bear in mind that using the electrical out- lets when the engine is off could cause thestarter battery to have too low of a chargelevel, which could limit other functionality. Accessories connected to the electrical outlets can be activated even when thevehicle electrical system is off or if precon-ditioning is used. For this reason, discon-nect plugs when they are not in use to pre-vent the starter battery from becoming dis-charged.

Position the accessory so that there isno risk of it injuring the driver or pas-sengers in the event of heavy brakingor a collision.
Pay attention to connected accessoriesas they can generate heat that couldburn passengers or the interior.
Using 12 V outlets1. Remove the stopper (tunnel console) or
fold down the cover (trunk/cargo com-partment) over the socket and plug in thedevice.
2. Unplug the device and put the stopper back in (tunnel console) or fold up thecover (trunk/cargo compartment) whenthe socket is not in use or left unattended.

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. If the vehicle is equipped with a temporary spare tire, this is secured to the cargo com-partment floor under the cover. The towingeyelet and tire sealing system are locatedunder the cargo compartment floor.

Loading recommendations
There are a number of things that are impor- tant to consider when carrying loads in or onthe vehicle.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessoriesreduces the vehicle's load-carrying capacity bythe corresponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position ofthe load.
Loading the cargo compartment/trunkKeep the following in mind when loading:
Position objects so they are pressing against the rear seat backrests.
Heavy objects should be positioned as lowas possible. Avoid placing heavy objectson folded-down seat backrests.
Cover sharp corners with a soft cloth orsimilar to help prevent damage to theupholstery.
Use the load anchoring eyelets and ten-sioning straps or similar to secure allobjects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured objectweighing 20 kg (44 pounds) can reach aprojectile weight equivalent to 1000 kg(2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm(4 in.) space between the objects and thewindow. Objects placed closer to thiscould impede the function of the inflatablecurtain concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure peo-ple in the vehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading longobjects. Otherwise, it is possible for theload to reach the gear lever or gear selectorand move it to a drive position – whichcould cause the vehicle to begin rolling.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.559
Extra cargo space
The rear seat backrests can be folded down *
to increase cargo space in the cargo compart- ment/trunk and simplify loading. If the rearseat backrests are folded down, make surethat no objects loaded into the vehicle preventthe WHIPS system for the front seats fromfunctioning correctly. The ski hatch *1
in the rear seat can be folded
down to carry skis or other long, thin objects.

Roof loads and load carriers
Volvo-developed load carriers are recom- mended for carrying loads on the roof of thevehicle.
Volvo load carriers are specially designed to help prevent damage to your vehicle and helpensure maximum safety while driving. Volvoload carriers are available from authorizedVolvo retailers. Carefully follow the installation instructions provided with the load carriers. Distribute the load evenly throughout the load carriers. Place heavier cargo at thebottom of the load.
Check periodically to ensure that the loadcarriers and load are properly secured.Secure the load firmly using tie straps orsimilar.
If the load is longer than the vehicle, suchas a canoe or kayak, attach the towingeyelet in its front outlet and secure the tiestraps in it.
The vehicle's wind resistance and fuelconsumption increase with the size of theload.
Drive smoothly. Avoid rapid acceleration,hard braking and fast cornering.
WARNING
The vehicle's center of gravity and driving characteristics are altered by roof loads. Follow the vehicle's specifications regar- ding weights and maximum permittedload.

MAINTENANCE AND SERVICE

NOTE
If the starter battery becomes discharged too many times, it will shorten its servicelife. The service life of the starter battery is affected by several factors, such as drivingconditions and climate. The startingcapacity of the battery reduces graduallyover time. The battery must therefore berecharged if the vehicle is not used or along period of time or if it is only drivenshort distances. Severe cold further limitsthe starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery shouldbe connected to a battery charger withautomatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.

Fuses and fuseboxes All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly. Do not touch anything that is not clearly described in the vehicle's Owner's Manual.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a prob-lem with the component. Volvo recommendscontacting an authorized Volvo workshop tohave the component checked.

Replacing fuses
All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amper-age.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If fuse replacement isperformed incorrectly, significant damagecan be caused to the electrical system.
