Starting and stopping thecombustion engine in Twin Enginevehicles
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. When driving on only the electricmotor, the vehicle may automatically start thecombustion engine due to outside circumstan-ces, e.g. low ambient temperatures. This is com-pletely normal. The combustion engine will alsoalways start when the hybrid battery is nearlyfully discharged.

Climate settings at low temperatures
At low ambient temperatures, the combustionengine will sometimes start automatically to helpachieve the desired passenger compartmenttemperature and air quality. The amount of timethe combustion engine is running can be affec-ted by
lowering the temperature
reducing blower speed
activating Pure drive mode.

Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, theelectric motor's driving range and power may be

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'smany 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
Shock absorbers
Instrument panel
Climate control settings
Select the drive mode that is best suited to thecurrent 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 emitany 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 unventilatedarea 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 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 or 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 bythe driver, the electric driveline will be utilized tohelp provide maximum additional power.
The vehicle also monitors the driving conditionsand automatically engages all-wheel drive if nec-essary. All-wheel drive and extra electric powerare always 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, thecombustion engine will start if the charge level inthe battery gets too low. The combustion enginewill also 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.

Constant 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 possible
control, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The Constant AWD drive mode isalways available regardless of the hybrid battery'scharge 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
The vehicle gets sportier driving characteris-tics and a faster acceleration 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. The
Power drive mode is always available regardlessof the hybrid battery's charge status.

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
Efficiency8 function can use map data to effec-tively distribute the electric power consumptionthroughout the trip.
This can lower fuel consumption in comparisonwith normal hybrid mode, in which the vehicle firstruns on electricity and then switches to the gaso-line engine when the hybrid battery is discharged.

Function
If the distance to the selected destination isgreater than the calculated range on the electricmotor, the function will distribute the electricpower to optimize consumption throughout thetrip. This makes it possible to avoid situations inwhich normal hybrid mode would otherwise use alarge portion of the electric power to e.g. use theelectric motor at high speeds on a highway andthen use the combustion engine at lower speedsduring city driving.
The greatest fuel savings are achieved when
the trip begins on a highway
the trip is between 50 and 100 km (30 and60 miles) long
the hybrid battery is fully charged at the startof 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.

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.

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.
