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 the Adaptive Cruise Control does notseem to respond with a speed increasewhen activated, it may be because thetime interval to the vehicle ahead isshorter than the set time interval.
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 ACC should maintain distance
* to the vehicle ahead
A number of different settings can be made for how Adaptive Cruise Control should maintain atime interval to the vehicle ahead. Settings are made using the DRIVE MODE controls. Select one of the following:
•
Eco - ACC will focus on providing optimal
fuel economy, which will increase the time interval to the vehicle ahead.
•
Comfort - ACC will focus on following the
set time interval to the vehicle ahead as smoothly as possible.
•
Dynamic - ACC will focus on following the
set time interval to the vehicle ahead more exactly, which could mean faster accelerationand heavier braking.

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:
•

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.

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.
