HYBRID INFORMATION

General information about Twin Engine Twin Engine vehicles are driven just like any other vehicle, but certain functions differ froma vehicle powered exclusively by gasoline.The electric motor powers the vehicle primar-ily at low speeds; the gasoline engine is usedat higher speeds or during more active driv-ing.
The instrument panel displays Twin Engine- specific information - charging information,selected drive mode, distance to dischargedbattery and hybrid battery charge level. Different drive modes can be selected while driving, e.g. electric power only or, if morepower is needed, a combination of electric andgasoline power. The vehicle calculates a com-bination of driveability, driving experience,environmental impact and fuel economy forthe selected drive mode. In order to function optimally, the hybrid bat- tery (and its electrical drive systems) and thegasoline engine (and its drive systems) mustbe at the correct operating temperature. Bat-tery capacity can be considerably reduced ifthe battery is too cold or too hot. Precondi-tioning prepares the vehicle's drive systemsand passenger compartment before driving tohelp reduce both wear and energy consump-tion. It also helps increase the hybrid battery'srange.The hybrid battery which powers the electricmotor is recharged using the charging cable. Itcan also be recharged during light braking andthrough engine braking in gear position
B. The
combustion engine can also help recharge thehybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical cur- rent to the vehicle, i.e. the ignition is switchedoff or the start battery is discharged, certainfunctions such as brakes, power steering, etc.will not work.
WARNING
If the vehicle does not have electrical cur- rent and both the electric motor and thegasoline engine are switched off, thebrakes cannot be used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another vehicle, as this could damage theelectric motor.
Exterior engine noise
Because there is no sound from the engine when only the electric motor is running, thevehicle is equipped with artificial exteriorbackground noise. This sound is intended tohelp warn children, pedestrians, cyclists, ani- mals, etc. outside the vehicle of the vehicle'sapproach.
High-voltage electrical current
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. These com-ponents and any orange wiring in the vehi-cle may only be handled by trained andqualified Volvo service technicians.
Do not touch anything that is not clearly described in this Owner's Manual.

Charging the hybrid battery
In addition to the conventional fuel tank, your vehicle is also equipped with a rechargeablelithium-ion hybrid battery.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
The hybrid battery can be recharged using the charging cable stored in a storage space in thetrunk.
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Anydamage to this system or to the hybrid bat-tery may result in the danger of overheat-ing, fire, or serious injury. If the vehicle isinvolved in a collision or subjected to flood-ing, fire, etc., have it inspected by a trainedand qualified Volvo service technician. Priorto this inspection, the vehicle should beparked outdoors at a safe distance fromany building or potentially flammable mate-rials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery dimin- ishes somewhat with age and use, whichcould result in increased use of the gaso-line engine and consequently, slightlyhigher fuel consumption.
WARNING
If the hybrid battery needs to be replaced, this may only be done by a Volvo retailer orauthorized Volvo workshop.

Charging cable handle and charging socket.
Charging status is indicated in three ways:
The indicator lights in the charging module (the unit connected to the wall outlet).
Indicator light in the vehicle's chargingsocket.
Images and text in the instrument panel.
The start battery is charged while the hybridbattery is charging and stops charging whenthe hybrid battery is fully charged. If the hybrid battery's temperature is below -10 ºC (14 ºF) or above 40 ºC (104 ºF), some
of the vehicle's functions may be reduced ornot available at all. The electric motor cannot be used if the bat- tery's temperature is too low or too high. If thePURE drive mode is selected, the gasolineengine will start.
Charging using the gasoline engine
The vehicle generates electrical current to charge the battery, e.g. when the driver lightly presses the brakepedal or when engine braking is used on down-grades.
The vehicle can also generate current to the hybrid battery to charge it. The hybrid battery can also be recharged by lightly depressing the brake pedal, i.e.during light braking. This converts thevehicle's kinetic energy to electricalenergy, which is used to charge the hybridbattery.
In gear position
B, the electric motor
brakes the vehicle when the acceleratorpedal is released and the hybrid battery isrecharged at the same time.
The combustion engine can also helprecharge the hybrid battery.

Charging current Charging current is used to charge the hybrid battery and precondition the vehicle. Charg-ing is performed by connecting a chargingcable between the vehicle's charging socketand a 120/240 V electrical socket (alternat-ing current).
When the charging cable is activated, a mes- sage will be displayed in the instrument paneland an indicator light in the vehicle's chargingsocket will illuminate. Charging current is pri-marily used for battery charging, but is alsoused for preconditioning. The vehicle's startbattery is charged along with the hybrid bat-tery.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
NOTE
In extremely cold or hot weather, part of the charging current is used to heat/cool the hybrid battery and the passen-ger compartment, resulting in a longercharging time.
The charging time is longer if precondi-tioning has been selected. The timerequired depends primarily on theambient temperature.
FuseThere are normally several 120/240 V power consumers in one fuse circuit, which meansthat more than one power consumer (e.g.lighting, vacuum cleaner, electric drill, etc.)may use the same fuse.
