limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in
certain situations. Auto-brake is active atspeeds under 15 km/h (9.3 mph).
WARNING
The auto-brake sub-function can only
detect and apply the brakes for other mov- ing vehicles – not for e.g. stationary obsta-
cles, cyclists or pedestrians.
CTA has certain limitations – The CTA sen- sors, for example, cannot "see" through otherparked vehicles or objects blocking the vehi-cle. Below are a few examples of situations in which CTA's field of vision may be initially lim-ited and approaching vehicles may thereforenot be detected until they are very close toyour vehicle:
73 Warning for crossing traffic when the vehicle is backing up.
74 Warning for crossing traffic when the vehicle is backing up.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle. The Park Assist system's rear sensors will be automatically deactivated if the vehicle isbacking up with a trailer connected to thevehicle's electrical system.
NOTE
When reversing with e.g. a trailer or bike carrier on the trailer hitch – without Volvooriginal trailer cables – the Parking Assistsystem may have to be turned off manuallyto prevent the sensors from reacting tothese.

HYBRID INFORMATION
394
General information about Twin Engine Twin Engine vehicles are driven just like any other vehicle, but certain functions differ froma vehicle powered exclusively by gasoline.The electric motor powers the vehicle primar-ily at low speeds; the gasoline engine is usedat higher speeds or during more active driv-ing.
The instrument panel displays Twin Engine- specific information - charging information,selected drive mode, distance to dischargedbattery and hybrid battery charge level. Different drive modes can be selected while driving, e.g. electric power only or, if morepower is needed, a combination of electric andgasoline power. The vehicle calculates a com-bination of driveability, driving experience,environmental impact and fuel economy forthe selected drive mode. In order to function optimally, the hybrid bat- tery (and its electrical drive systems) and thegasoline engine (and its drive systems) mustbe at the correct operating temperature. Bat-tery capacity can be considerably reduced ifthe battery is too cold or too hot. Precondi-tioning prepares the vehicle's drive systemsand passenger compartment before driving tohelp reduce both wear and energy consump-tion. It also helps increase the hybrid battery'srange.The hybrid battery which powers the electricmotor is recharged using the charging cable. Itcan also be recharged during light braking andthrough 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 cur- rent to the vehicle, i.e. the ignition is switchedoff or the start battery is discharged, certainfunctions such as brakes, power steering, etc.will not work.
WARNING
If the vehicle does not have electrical cur- rent and both the electric motor and thegasoline engine are switched off, thebrakes cannot be used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another vehicle, as this could damage theelectric motor.
Exterior engine noise
Because there is no sound from the engine when only the electric motor is running, thevehicle is equipped with artificial exteriorbackground noise. This sound is intended tohelp warn children, pedestrians, cyclists, ani- mals, etc. outside the vehicle of the vehicle'sapproach.
High-voltage electrical current
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly. These com-ponents and any orange wiring in the vehi-cle may only be handled by trained andqualified Volvo service technicians.
Do not touch anything that is not clearly described 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.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
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. Anydamage to this system or to the hybrid bat-tery may result in the danger of overheat-ing, fire, or serious injury. If the vehicle isinvolved in a collision or subjected to flood-ing, fire, etc., have it inspected by a trainedand qualified Volvo service technician. Priorto this inspection, the vehicle should beparked outdoors at a safe distance fromany building or potentially flammable mate-rials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery dimin- ishes somewhat with age and use, whichcould result in increased use of the gaso-line engine and consequently, slightlyhigher fuel consumption.
WARNING
If the hybrid battery needs to be replaced, this may only be done by a Volvo retailer orauthorized 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 start battery is charged while the hybridbattery is charging and stops charging whenthe hybrid battery is fully charged. 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 ornot available at all. The electric motor cannot be used if the bat- tery's temperature is too low or too high. If thePURE drive mode is selected, the gasolineengine will start.
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 down-grades.
The vehicle can also generate current to the hybrid battery to charge it. The hybrid battery can also be recharged by lightly depressing the brake pedal, i.e.during light braking. This converts thevehicle's kinetic energy to electricalenergy, which is used to charge the hybridbattery.
In gear position
B, the electric motor
brakes the vehicle when the acceleratorpedal is released and the hybrid battery isrecharged at the same time.
The combustion engine can also helprecharge the hybrid battery.
