General information about TwinEngine
Twin Engine vehicles are driven just like anyother vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe-cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level.
Different drive modes can be selected while driv-ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode.
In order to function optimally, the hybrid battery(and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range.
The hybrid battery which powers the electricmotor is recharged using the charging cable. It
can also be recharged during light braking andthrough engine braking in gear position B. Thecombustion engine can also help recharge thehybrid battery.

Important
No electrical current
Keep in mind that if there is no electrical currentto the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.

WARNING
If the vehicle does not have electrical currentand both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.

Towing not permitted
Never tow a Twin Engine vehicle behind anothervehicle, as this could damage the electric motor.

Exterior engine noise
WARNING
Please be aware that there is no sound fromthe engine when the vehicle is being poweredby the electric motor and it may be difficult todetect by children, pedestrians, cyclists andanimals. This is especially true at low speeds.
High-voltage electrical current
WARNING
A number of electrical components in TwinEngine Plug-in Hybrid vehicles use high-volt-age current and can be extremely dangerousif handled incorrectly. These components andany orange wiring in the vehicle may only behandled by trained and qualified Volvo servicetechnicians.
Do not touch anything that is not clearly descri-bed in this Owner's Manual.

Charging the hybrid battery
In addition to the conventional fuel tank, yourvehicle 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 chemicalsincluding engine exhaust, carbon monoxide,phthalates, and lead, which are known to theState of California to cause cancer and birthdefects or other reproductive harm. To mini-mize exposure, avoid breathing exhaust, donot idle the engine except as necessary, serv-ice your vehicle in a well ventilated area andwear gloves or wash your hands frequentlywhen servicing your vehicle. For more infor-mation go to www.P65Warnings.ca.gov/passenger-vehicle.
The hybrid battery can be recharged using thecharging cable stored in a storage space in thetrunk.
WARNING
The hybrid electrical system in your vehicleuses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or subjected to flooding, fire, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends onthe charging current used.

NOTE
The capacity of the hybrid battery diminishessomewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.

WARNING
If the hybrid battery needs to be replaced, thismay 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 hybrid bat-tery is charging and stops charging when thehybrid battery is fully charged.
If the hybrid battery's temperature is below-10 ºC (14 ºF) or above 40 ºC (104 ºF), some ofthe vehicle's functions may be reduced or notavailable at all.
The electric motor cannot be used if the battery'stemperature is too low or too high. If the PUREdrive mode is selected, the gasoline engine willstart.

Charging using the gasoline engine
The vehicle generates electrical current to charge thebattery, e.g. when the driver lightly presses the brakepedal or when engine braking is used on downgrades.
The vehicle can also generate current to thehybrid battery to charge it.
The hybrid battery can also be recharged bylightly depressing the brake pedal, i.e. duringlight braking. This converts the vehicle'skinetic energy to electrical energy, which isused to charge the hybrid battery.
In gear position B, the electric motor brakesthe vehicle when the accelerator pedal isreleased and the hybrid battery is rechargedat the same time.
The combustion engine can also helprecharge the hybrid battery.

Charging current
Charging current is used to charge the hybridbattery and precondition the vehicle. Charging isperformed by connecting a charging cablebetween the vehicle's charging socket and a120/240 V electrical socket (alternating cur-rent).
When the charging cable is activated, a messagewill be displayed in the instrument panel and anindicator light in the vehicle's charging socket willilluminate. Charging current is primarily used forbattery charging, but is also used for precondi-tioning. The vehicle's start battery is chargedalong with the hybrid battery.

CAUTION
Never detach the charging cable from the120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged in suchcircumstances. Always interrupt charging firstand then disconnect the charging cable – firstfrom the vehicle's charging socket and thenfrom the 120/240 V outlet.
NOTE
In extremely cold or hot weather, part ofthe charging current is used to heat/coolthe hybrid battery and the passengercompartment, resulting in a longer charg-ing time.
The charging time is longer if precondi-tioning has been selected. The timerequired depends primarily on the ambi-ent temperature.

Fuse
There are normally several 120/240 V powerconsumers in one fuse circuit, which means thatmore than one power consumer (e.g. lighting,vacuum cleaner, electric drill, etc.) may use thesame fuse.
