Drive at a constant speed whenever possible.
See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Twin Engine vehicles
If possible, precondition the vehicle with thecharging cable before driving.
If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
Choose the Pure drive mode to help mini-mize electric power consumption.
In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.

Trip computer
The vehicle's trip computer registers data whiledriving such as mileage, fuel consumption andaverage speed.
To help promote fuel-efficient driving, data isrecorded on both current and average fuel con-sumption. Data from the trip computer can bedisplayed in the instrument panel.
Example of trip computer information in the instrumentpanel.1
The trip computer includes the following gauges:
Trip odometer
Odometer
Current fuel consumption
Distance to empty tank
Distance to discharged battery
Tourist - alternative speedometer
Unit standards for distance, speed, etc. can bechanged via system settings in the center display.
Trip odometer
There are two trip odometers: TM and TA.
TM can be reset manually and TA is reset auto-matically if the vehicle is not used for four hours.
During a drive, the trip odometer registers dataon:
Mileage
Driving time
Average speed
Average fuel consumption
The readings since the trip odometer's last resetare displayed.

Odometer
The odometer records the vehicle's total mileage.This reading cannot be reset.

Current fuel consumption
This gauge shows the vehicle's fuel consumptionat that moment. The reading is updated aboutonce a second.

Distance to empty tank
The trip computer calculates the distance thatcan be driven on the fuel remaining in the tank.

This calculation is based on average fuel con-sumption during the last 30 km (20 miles) andthe amount of fuel remaining in the tank.
When the gauge displays "----", there is notenough fuel remaining to calculate the remainingmileage. Refuel as soon as possible.

NOTE
This may vary if your driving style changes.
An economical driving style will generallyincrease how far you can drive on a certainamount of fuel.

Distance to discharged battery
The gauge shows the approximate dis-tance that can be driven with theremaining current in the hybrid battery.
When the gauge displays "----", there is littlecharge remaining in the battery and distancecannot be reliably calculated.
This calculation is based on average consump-tion with a normally loaded vehicle in normal driv-ing conditions, and takes into account whetherthe air conditioning is on or off. Changing drivemodes from Hybrid to Pure may increase thecalculated distance because Pure mode hasreduced climate control settings (ECO Climate).
NOTE
This may vary if your driving style changes.
An economical driving style will generallyincrease how far you can drive on a certainamount of fuel.

Starting values for fully charged hybrid
battery
Because it is difficult to predict driving style andother factors that affect the range of electricmotors, Volvo uses a starting value when thevehicle is fully charged. This starting value pro-vides an "up to" amount instead of a predictionon the range of the electric current in the motor.The difference in starting value between Hybridand Pure is because the vehicle is permitted touse more current from the hybrid battery in Puremode, and because the vehicle switches to ECOClimate.

Mileage when using electric motor
To achieve the longest possible mileage whenusing the electric motor, the driver of an electricvehicle also needs to think about conservingelectricity. The more electricity consumers(stereo, heated windows/mirrors/seats, very coldair from climate control system, etc.) that areactive, the shorter the potential mileage.
NOTE
In addition to high electrical consumption inthe passenger compartment, rapid accelera-tion, sudden braking, high speeds, heavyloads, low ambient temperatures and drivingup hills can reduce possible driving distance.

Tourist - alternative speedometer
The alternative digital speedometer makes it eas-ier to drive in countries where speed limit signsare shown in a different measurement unit thanthe one shown in the vehicle's gauges.
When used, the digital speed is displayed in theopposite unit to that shown in the analog speed-ometer. If mph is used in the analog speedome-ter, the equivalent speed in km/h will be shownin the digital speedometer.

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.

STARTING AND DRIVING

HYBRID
This is the default mode in which the electricmotor and combustion engine work together.
The vehicle starts in Hybrid mode. The controlsystem uses both the electric motor and the gas-oline engine - separately or in tandem - and cal-culates optimal utilization with regard to perform-ance, fuel consumption and comfort. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat/cooling in thepassenger compartment, etc.
If there is sufficient charge in the battery, it ispossible to drive solely on electric power. Whenthe accelerator pedal is pressed, only the electricmotor will be activated until the battery reaches acertain charge level. Above this level, the currentin the battery cannot supply the power requestedby the accelerator pedal and the combustionengine will start.
When the hybrid battery's charge level is low, thecombustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outletusing a charging cable, or activate Charge inFunction view to reset the option of only usingthe electric motor.
This drive mode is designed for low energy con-sumption with an optimized mix between theelectric motor and gasoline engine, without com-promising on climate comfort or driving experi-ence. When faster acceleration is requested by
the driver, the electric driveline will be utilized tohelp provide maximum additional power. Thevehicle also monitors the driving conditions andautomatically engages all-wheel drive if neces-sary. All-wheel drive and extra electric power arealways available regardless of the battery'scharging status.

Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge willbe displayed in the instrument panel. The gaugewill indicate the amount of electrical currentrequired when the driver depresses the accelera-tor pedal. The marker between the lightning andthe drop shows how much current is available.
The instrument panel gauge when both the electricmotor and the combustion engine are being used.
The instrument panel also shows howmuch current is being restored to thebattery (regenerated) during light brak-ing.
PURE
Uses the electric motor only, with the lowestpossible energy consumption and carbondioxide emissions.
This drive mode maximizes the use of the hybridbattery. Certain climate system functions arereduced to provide the longest distance usingonly electricity.
Pure mode is available when the hybrid battery issufficiently charged. Even in Pure mode, the com-bustion engine will start if the charge level in thebattery gets too low. The combustion engine willalso start
if the vehicle's speed goes above 125 km/h(78 mph)
if the driver requests more power than theelectric motor can provide
if factors such as cold weather affect thesystem or components.
This drive mode is optimized for maximum drivingdistance with electric propulsion and is primarilyintended for use in city driving. Pure helps pro-vide the lowest possible consumption even whenthe hybrid battery is fully discharged. ECO climateis activated to control the climate in the passen-ger compartment, and in slippery road conditionsslightly more wheel spin may be permitted beforeall-wheel drive is automatically activated.

ECO Climate
In Pure mode, ECO climate is automatically acti-vated in the passenger compartment to helpreduce energy consumption.

NOTE
When the Pure drive mode is activated, set-tings for certain climate system and electricityconsuming functions are reduced. Some ofthese settings can be reset manually, but fullfunctionality will only be restored by leavingPure mode or adapting the Individual drivemode to full climate system functionality.
If condensation forms on the windows, tap themax defroster button, which will function normally.

AWD
Improves the vehicle's traction and handlingby increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possiblecontrol, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The AWD drive mode is always availableregardless of the hybrid battery's charge status.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
In the other drive modes, the vehicle automati-cally adapts the need for all-wheel drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
POWER
Power mode is designed to provide sportierdriving characteristics and a faster accelera-tion response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster and suspension is stiffer.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
This drive mode is optimized for maximum per-formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. ThePower drive mode is always available regardlessof the hybrid battery's charge status.

INDIVIDUAL
Customizes drive mode to personal preferen-ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv-ing characteristics. These settings will be storedin your driver profile.
Individual drive mode is only available if it hasbeen activated in the center display.
