–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the cur-
rent time interval.
In order to follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval tovary considerably in certain situations. For exam-ple, at low speeds and short distances to thevehicle ahead, Pilot Assist increases the timeinterval slightly.
NOTE
• The greater the vehicles' speed, the greater the distance between them for aset time interval.
• Only use the time intervals permitted bylocal traffic regulations.
• If Pilot Assist does not seem to respondwith a speed increase when activated, itmay be because the time interval to thevehicle ahead is shorter than the set timeinterval.
WARNING
•Only use a time interval suitable for the current traffic conditions.
• The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.
Setting how Pilot Assist should maintain distance
* to the vehicle ahead
The driver can choose different drive modes to determine how Pilot Assist should maintain atime interval to the vehicle ahead. Settings are made using the DRIVE MODE controls. Select one of the following:
•
Eco - Pilot Assist will focus on providing
optimal fuel economy, which will increase the time interval to the vehicle ahead.
•
Comfort - Pilot Assist will focus on following
the set time interval to the vehicle ahead as smoothly as possible.
•
Dynamic - Pilot Assist will focus on follow-
ing the set time interval to the vehicle ahead more exactly, which could mean faster accel-eration and heavier braking.

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.

Charging the hybrid battery In addition to the conventional fuel tank, your vehicle is also equipped with a rechargeablelithium-ion hybrid battery.
The hybrid battery can be recharged using the charging cable stored in a storage space in thecargo compartment.
WARNING
The hybrid electrical system in your vehicle uses 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 on the charging current used.
NOTE
The capacity of the hybrid battery diminishes somewhat 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, this may only be done by Volvo retailer or author-ized 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 hybrid battery's charging process alsocharges the vehicle's start battery. If the hybrid battery's temperature is below -10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not available 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 the battery, e.g. when the driver lightly presses the brakepedal or when engine braking is used on downgrades.
The vehicle can also generate current to the hybrid 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.

Transmission The transmission is part of the vehicle's driveline (power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis- sion and an electric motor for rear-wheel drive.The number of gears allows the engine's torqueand power band to be effectively utilized. Two ofthe gears are overdrive gears that save fuel whendriving at a constant engine speed. The steering wheel paddles
* can be used to shift up or down
manually. The instrument panel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.

Shiftlock The automatic transmission's shiftlock function helps prevent inadvertently moving the gearselector between different positions.
Automatic shiftlockThe automatic shiftlock has a separate safety system.
From Park - P
To move the gear selector from the P position,
the brake pedal must be depressed and the igni- tion in mode II.
From Neutral - N
If the gear selector is in N and the vehicle has
been stationary for at least 3 seconds (with or without the engine running), the gear selector willbe locked in that position. To move the gear selector from N to another
gear, the brake pedal must be depressed and the ignition in mode II.
Messages in the instrument panelIf the gear selector is locked in position, a mes- sage will appear in the instrument panel, e.g.
Gear lever Press brake pedal to activate
gear lever.
There is no mechanical shiftlock function.

• Gear selector positions for automatic trans- missions (p. 429)
The kickdown function
Kickdown is used when maximum acceleration is needed, e.g. when passing.
When the accelerator pedal is depressed all the way to the floor (past the normal full acceleratorposition), the transmission will automaticallyengage kickdown, i.e. immediately shift down to alower gear. If the accelerator pedal is released from the kick- down position, the transmission will automaticallyshift up again.
Safety function
The transmission control module is equipped with a downshift protection feature to help prevent theengine from overheating. In some conditions, the transmission will prevent downshifting/kickdown if this would lead to suchhigh engine speed (rpm) that the engine couldbe damaged. If the driver still attempts downshift-ing or kickdown at a high rpm, nothing will hap-pen and the original gear will remain selected. With kickdown, the vehicle can downshift one or more steps at a time depending on the enginespeed. The vehicle upshifts when the engine rea-ches its maximum rpm to prevent engine dam-age.

Gear indicator
*
The gear indicator in the instrument panel shows the gear currently being used for manual shiftingand indicates when another gear should beselected to optimize fuel economy.
For eco-friendly driving when manually shifting, it is important to use the correct gear and to shiftgears in good time. The gear indicator in the instrument panel shows the gear currently being used and indicates withan upward-facing arrow if a higher gear shouldbe selected. The gear indicator is shown in gear B .

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.

OFF ROAD
•Maximizes the vehicle's ability to traverse dif- ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill DescentControl are activated. This drive mode is only available at low speeds, up to 40 km/h (25 mph). If this speed is excee-ded, Off road mode will be cancelled and AWDmode will be activated instead. All-wheel drive requires both the combustion and electric motor to be in continuous operation,which results in higher fuel consumption. In Off road mode, a compass will be displayed between the speedometer and the tachometer inthe instrument panel. The permissible speedrange will be shown in the speedometer. This drive mode is optimized for maximum control when driving at low speeds on very poor roads or difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle in all-wheel drive. The Hill Descent Control func-tion facilitates controlled driving on steep down-grades.NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
Due to the increased ground clearance, if the OFF ROAD mode was selected when theengine was switched off, the suspension willlower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when towing a trailer without an electrical connec-tion. This could result in damage to the pneu-matic suspension system's bellows.
AWD
• Improves the vehicle's traction and handling by 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 sportier driving 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, suspension is stiffer and ground clearance is lower 4
to help reduce body roll when cornering.
Both the combustion engine and the electric motor 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.

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 recharge thehybrid battery. A regenerative function isintegrated in the brake pedal and can beaugmented by the electric motor's brakingcapacity when the gear selector is in mode B
.
• Higher speeds increase energy consumption - air resistance increases with speed.
• Activate the
Hold function in the Function
view at high speeds when traveling farther than 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 Twin Engine provides a combination of good fueleconomy, low emissions and high performance.
For energy-efficient driving:
• Select the Pure drive mode to help maximize driving 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 Function
view at high speeds when traveling farther than 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.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driving longdistances.
Check that:
• the engine is running properly and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• the brake pedal is functioning optimally
• all lights are working
‒ adjust the headlight
height 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 driving in 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 hard driving or in hot weather.
•
Check the condition and charge level of the start 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 conditionsFor 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 tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con- trolled conditions to learn how the vehicle reacts.
