Using the electric or combustion
engine
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time.
Its primary function is to use the motor/engineand the current available in the hybrid battery asefficiently as possible based on the characteris-tics of the various drive modes and the poweroutput requested by the driver by pressing theaccelerator pedal.
In certain cases, temporary limitations in the sys-tem or mandatory functions to help maintain alow overall emissions level may result in greateruse of the combustion engine.

Energy distribution in hybrid mode
using map data*
The Hybrid drive mode is the vehicle's defaultdrive mode in which the electric motor and thecombustion engine work separately or togetherin hybrid mode. If a destination has beenselected in the navigation system*, the Predictive
Efficiency4 function can use map data to effec-tively distribute the electric power throughout thetrip.
This can lower fuel consumption in comparisonwith normal hybrid mode, in which the vehicle firstruns on electricity and then switches to the com-bustion engine when the hybrid battery is dis-charged.
If the distance to the destination is greater thanthe calculated range on the electric motor, thefunction will distribute electric power optimally forthe entire trip. This makes it possible to avoid sit-uations in which normal hybrid mode would oth-erwise use a large portion of the electric powerto e.g. use the electric motor at high speeds on ahighway and then use the combustion engine atlower speeds during city driving.
The greatest fuel savings are attained when thetrip begins on a highway, is between 50 and 100km (30 and 60 miles) long, and the hybrid batteryis fully charged at the start of the trip.
Requirements for the function
Certain conditions must be met for the functionto be possible:
A destination must be set in the navigationsystem and the distance to the destinationmust be longer than the possible rangeusing only the electric motor.
Hybrid drive mode must be selected.
The Hold and Charge functions must bedisabled.
The hybrid battery must be charged.

Usage tips
If you commute and it is not possible to chargethe vehicle at work, enter your workplace as awaypoint and your home as the destination. Dis-charging of the hybrid battery will then be distrib-uted over the entire commute to and from work.
Add similar commutes, i.e. the route between twocharges, as Favorites in the navigation system tofacilitate access.

Leveling control* and suspension
Self-leveling and suspension functions are con-trolled automatically.
Rear leveling control keeps the rear section ofthe vehicle at the same height regardless of load.Leveling control may also remain active when thevehicle is parked.

Shock absorbers (Four-C)
The shock absorbers are adapted to the selecteddrive mode and vehicle speed. The shock absorb-ers are normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface and the vehicle's acceleration,braking and cornering.
Transporting
When transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing and result in damage.

Economical driving
Drive economically and more environmentallyconscious by thinking ahead, avoiding rapidstarts and stops and adapting driving style andspeed to the current traffic conditions.
To help achieve the greatest distance with thelowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging itinto an electrical outlet. Make it a habit toalways begin trips with the hybrid battery fullycharged.
Locate charging stations along your route.
If possible, choose parking spots with charg-ing stations.

NOTE
Charge the vehicle from the electricity grid asoften as possible!

Preconditioning
Whenever possible, precondition the vehiclebefore driving by connecting the chargingcable to an electrical outlet.
Avoid parking the vehicle somewhere wherethe interior will become too hot or too coldwhile the vehicle is parked. If possible, parkthe vehicle in a climate-controlled garage.
During a short drive after passenger com-partment preconditioning, turn off the pas-senger compartment fan or the air condition-ing in a hot climate.
If preconditioning is not possible when it iscold outside, use seat and steering wheelheating first. Avoid heating the entire pas-senger compartment to reduce the amountof current being taken from the hybrid bat-tery.

Driving
Choose the Pure drive mode to help mini-mize electric power consumption.
Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking. This drive mode has the lowestpower consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustion engine,especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will help rechargethe hybrid battery. A regenerative function isintegrated in the brake pedal and can beaugmented by the electric motor's brakingcapacity when the gear selector is in modeB.
Higher speeds increase energy consumption- air resistance increases with speed.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the Chargefunction to charge the hybrid battery. Charg-ing the battery using the combustion engine
increases fuel consumption and carbon diox-ide emissions.
In a cold climate, reduce heating of the wind-shield/rear window, mirrors, seats and thesteering wheel.
Maintain the correct pressure in the tires andcheck pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for advice onsuitable tires.
Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal. Usethe brakes instead.

Using the electric motor only
When using the electric motor, Volvo TwinEngine provides a combination of good fueleconomy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximizedriving range using only the electric motor.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel's hybrid gauge to see avail-able electric power and avoid starting thecombustion engine unnecessarily.
When braking is necessary, brake gentlyusing the brake pedal. This will recharge thehybrid battery.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Reduce current consumption in the passen-ger compartment by reducing e.g. fan speed,electric heating, or air conditioning use.
Also follow the general economical driving adviceregarding speed, tires and load to maximizerange.

Factors affecting electric motorrange
A number of factors affect the electric motor'sdriving range. The ability to achieve a long driv-ing range varies according to the outside condi-tions and to how the vehicle is driven.
The certified value for the distance that can bedriven using the electric motor should not beconsidered an expected driving range. The actualrange is dependent on a number of factors.

Factors affecting driving range
The driver can influence some factors affectingdriving range, but not all.
The longest range is achieved under very favora-ble conditions when all factors positively influ-ence range.

Factors the driver cannot control
There are several outside conditions that affectrange to varying degrees:
the current traffic situation
driving short distances
topography
ambient temperature and headwinds
road conditions and road surface.
The following table shows the approximate rela-tionship between ambient temperature and driv-ing range with normal climate settings and withclimate settings turned off.
Up to a certain limit, warmer ambient tempera-tures increase the electric motor's driving range.
Ambient tem-peratureClimate set-tings turnedoff
Normal cli-mate set-tings
30 °C (86 °F)95 % 80 %

Factors the driver can control
The driver should be aware that the following fac-tors help conserve energy and improve drivingrange:
charging the battery regularly
preconditioning
Pure drive mode
climate control settings
speed and acceleration
the Hold function
tires and tire pressure.
The following table shows the approximate rela-tionship between constant speed and drivingrange. Driving at a lower constant speed helpsincrease the electric motor's driving range.
Constant speed
100 km/h (62 mph) 50 %
80 km/h (50 mph)70 %
60 km/h (37 mph) 90 %
50 km/h (31 mph) 100 %

"Hold" and "Charge" functions
In certain situations, it can be useful to controlthe hybrid battery's charge level while driving.This is possible with the Hold and Charge func-tions.
Hold and Charge are available in all drivemodes. The functions will switch off if Pure drivemode is activated.

Function buttons for Hold and Charge
The functions can be activated in the center dis-play's Function view.

Hold
Battery level sustained forlater use.
This function retains the chargein the hybrid battery for theelectric motor and saves availa-ble electrical current for use ata later time, such as when driving in an urbanarea or residential neighborhood.
The vehicle will function as in normal hybrid driv-ing with a discharged battery - in addition toreusing energy from e.g. regenerative braking, thecombustion engine will be used more frequentlyto maintain the charge in the battery.

Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that:
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before drivingin cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
Make sure the engine coolant contains 50%antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
Keep the fuel tank well filled to prevent con-densation from forming.
Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.

CAUTION
Low-viscosity oil should not be used with harddriving or in hot weather.
Check the condition and charge level of thestart battery. Cold weather places greaterdemands on the start battery and reduces itscapacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.
Slippery driving conditions
For optimal traction and roadholding, Volvo rec-ommends using snow tires on all wheels when-ever there is a risk of snow or ice on the road.

NOTE
Certain countries require use of winter tiresby law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con-trolled conditions to learn how the vehicle reacts.

Driving through standing water
Driving the vehicle through a deep pool of stand-ing water on a water-covered roadway is calledfording. This must be done with great caution.
To prevent damage to the vehicle when drivingthrough water (e.g. on flooded roads):
Do not drive in water higher than the floor ofthe vehicle. If possible, check the depth ofthe water at its deepest point before drivingthrough it. Be particularly careful when driv-ing through flowing water.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to help avoidthe risk of corrosion.
