Park Assist front, rear and sides
Park Assist has different parameters depending on which part of the vehicle is approaching anobstacle.
Back
Note: This illustration is general and details may vary depending on model.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored begins approx. 1.5 meters (5 feet) behind the vehicle. The rear sensors will be automatically deactivated if the vehicle is backing up with a trailer attached.
NOTE
When reversing with e.g. a trailer or bike car- rier on the trailer hitch – without Volvo originaltrailer cables – the Parking Assist system mayhave to be turned off manually to prevent thesensors from reacting to these.
Side sensors
Park Assist's side sensors are automatically acti- vated when the engine is started. They are activeat speeds below 10 km/h (6 mph). The distance monitored begins approx. 30 cm (1 ft) from the sides. The audible signal for obsta-cles along the sides of the vehicle is emittedfrom the side speakers.
Front camera
Note: This illustration is general and details may vary depending on model.
Park Assist's front sensors are automatically acti- vated when the engine is started. The front sen-sors are active at speeds below 10 km/h(6 mph). The distance monitored begins approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivated when the parking brake is applied or when P
is selected on vehicles with automatic trans- mission.

Parking with Park Assist Pilot Park Assist Pilot (PAP 126
) helps the driver park
using three different steps. The function can also help the driver pull out of a parking space.
NOTE
The PAP function measures the space and steers the vehicle – the driver's role is to:
• keep close watch of the area around thevehicle
• follow the instructions on the center dis-play
• change gears (reverse/forward) – a"ping" sound indicates when the drivershould change gears
• regulate and maintain a safe speed
• apply the brakes and stop.
Information about the actions required by the driver are provided in the center display usingsymbols, graphics and/or text. PAP can be activated if the following criteria have been met after the engine is started: •
No trailer is hitched to the vehicle
• Your vehicle's speed is lower than 30 km/h (20 mph).

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.

Charging current Charging current is used to charge the hybrid battery and precondition the vehicle. Charging isperformed by connecting a charging cablebetween the vehicle's charging socket and a120/240 V electrical socket (alternating cur-rent).
When the charging cable is activated, a message will be displayed in the instrument panel and anindicator light in the vehicle's charging socket willilluminate. Charging current is primarily used forbattery charging, but is also used for precondi-tioning. The vehicle's start battery is chargedalong with the hybrid battery.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged in suchcircumstances. Always interrupt charging firstand then disconnect the charging cable – firstfrom the vehicle's charging socket and thenfrom the 120/240 V outlet.
NOTE
• In extremely cold or hot weather, part of the charging current is used to heat/coolthe hybrid battery and the passengercompartment, resulting in a longer charg-ing time.
• The charging time is longer if precondi-tioning has been selected. The timerequired depends primarily on the ambi-ent temperature.
There are normally several 120/240 V power consumers in one fuse circuit, which means thatmore than one power consumer (e.g. lighting,vacuum cleaner, electric drill, etc.) may use thesame fuse.
