28 goal. In addition to continuous environmental refinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
• Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• 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 mode B
to utilize the electric motor's braking func-
tion when the accelerator pedal is released. This helps charge the hybrid battery.

IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regarding vehicle safety. IntelliSafe consists of a number ofsystems, both standard and optional, that aredesigned to help make driving safer, preventaccidents and protect passengers and otherroad users.
SupportIntelliSafe includes driver support functions such as Adaptive cruise control * which helps the driver
to maintain an even speed combined with a pre- selected time interval to the vehicle ahead. Pilot Assist 4
helps the driver keep the vehicle in
the current traffic lane by providing steering assistance and maintaining an even speed and aset time interval to the vehicle ahead. Park Assist Pilot * helps the driver pull into and
out of parking spaces. Other examples of systems that can help the driver are the Active main beam, Cross Traffic Alert (CTA) * and Blind Spot Information (BLIS) *
systems.
PreventionCity Safety is a function intended to help prevent accidents. The function can help prevent or miti-gate a collision with pedestrians, cyclists, largeanimals or other vehicles. Light, sound and pulsa-tions in the brake pedal are provided to alert of a

Trip computer The vehicle's trip computer registers and calcu- lates data while driving such as mileage, fuelconsumption and average speed.
To help promote fuel-efficient driving, data is recorded on both current and average fuel con-sumption. Data from the trip computer can bedisplayed in the instrument panel.
Trip computer information in the instrument panel1
.
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 be changed via system settings in the center display.
Trip odometerThere 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 data on:
• Mileage
• Driving time
• Average speed
• Average fuel consumption
The readings since the trip odometer's last resetare displayed.
OdometerThe odometer records the vehicle's total mileage.This reading cannot be reset.
Current fuel consumptionThis gauge shows the vehicle's fuel consumptionat that moment. The reading is updated aboutonce a second.
Distance to empty tankThe 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 not enough 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 generally increase how far you can drive on a certainamount of fuel.
Distance to discharged batteryThe gauge shows the approximate dis-tance that can be driven with theremaining current in the hybrid battery.
When the gauge displays "----", there is little charge 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 drive modes from
Hybrid to Pure may increase the
calculated distance because Pure mode has
reduced climate control settings (ECO Climate).

Starting values for fully charged hybrid
battery
Because it is difficult to predict driving style and other 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 to
use more current from the hybrid battery in Puremode, and because the vehicle switches to ECO Climate.
Mileage when using electric motor
To achieve the longest possible mileage when using 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 in the passenger compartment, rapid accelera-tion, sudden braking, high speeds, heavyloads, low ambient temperatures and drivingup hills can reduce possible driving distance.
Tourist - alternative speedometerThe 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 the opposite 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 shown
in the digital speedometer.

HYBRID INFORMATION

General information about TwinEngine
Twin Engine vehicles are driven just like any other 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 electric motor, is recharged using the charging cable. Itcan also be recharged during light braking and through 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 current to 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 current and 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 another vehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Keep in mind that the vehicle does not emit any engine noise when using the electricmotor and may therefore be difficult to detectfor children, pedestrians, cyclists or animals.This is especially true at low speeds, e.g. inparking lots.
High-voltage electrical current
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure. These componentsand any orange wiring in the vehicle may onlybe handled by trained and qualified Volvoservice technicians.
Do not touch anything that is not clearly descri- bed in this Owner's Manual.

Drive modes
Drive modes affect the vehicle's driving charac- teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle's many functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode: • Steering
• Engine/transmission/all-wheel drive
• Brakes
• Pneumatic suspension
* and shock absorbers
• Instrument panel
• Climate control settings
Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
WARNING
Keep in mind that the vehicle does not emit any engine noise when using the electricmotor and may therefore be difficult to detectfor children, pedestrians, cyclists or animals.This is particularly true at low speeds, e.g. inparking lots.
WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and the com-bustion engine switched off. The engine willstart automatically if the charge level in thehybrid battery is low and the resulting exhaustgases can be very harmful to people and ani-mals.
HYBRID
• This is the default mode in which the electric motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control system 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. At highspeeds, ground clearance is automatically low- ered 4
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the need for heat/cooling in the passenger compart-ment, etc. If there is sufficient charge in the battery, it is possible 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, the combustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outlet using a charging cable, or activate
Charge in
Function view to reset the option of only using the 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 bythe 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.
