Steering assistance during collision risks limitations
The function may have limited functionality in certain situations and not intervene, e.g.:
for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no sidelane markings
outside the speed range 60-140 km/h(37-87 mph)
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
Functionality may also be reduced in other sit-uations, such as: road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

The parking sequence is cancelledA parking sequence will be cancelled if: the driver moves the steering wheel
the vehicle's speed exceeds 7 km/h (4 mph)
the driver taps
Cancel in the center dis-
play
when the anti-lock brakes or the Elec- tronic stability control are engaged - e.g.when a wheel loses grip on a slippery road
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
when, while parking, the parking sensorsdetect a vehicle or pedestrian in the vehi-cle's intended direction of travel behind orin front of the vehicle, the auto-brake func-tion will bring the vehicle to a standstill.
A message in the center display will explainwhy the parking sequence was cancelled.
CAUTION
Under certain circumstances, the function may not be able to find parking spaces –one reason may be that the sensors aredisrupted by external sound sources thatemit the same ultrasonic frequencies thatthe system works with. Examples of such sources include horns, wet tires on asphalt, pneumatic brakes,exhaust noise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensors reduce their function and can make meas-urement impossible.
Driver responsibilityThe driver should keep in mind that the func- tion is a parking aid ‒
not an infallible fully
automatic system. The driver must always beprepared to take control and cancel a parkingsequence if necessary. There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for deter-mining if the space suggested by the func-tion is suitable for parking.
Do not use the function when using snowchains or a temporary spare tire.
Do not use the function if there are anyobjects protruding from the vehicle.
Heavy rain or snowfall may inhibit PAP'sability to accurately measure a parkingspace.
While searching and measuring the park-ing space, the function may be unable todetect objects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect suffi-cient space for maneuvering the vehicle.
Use approved tires 105
inflated to the cor-
rect tire pressure because this affects thefunction's ability to provide parking assis-tance.
The function is based on the way the vehi-cles are parked behind and in front of yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims
105
"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

Open the charger door and remove the charging socket's protective cover. Pushthe charging handle all the way into thevehicle's socket.2. The charging cable handle will lock into
place and charging will begin within5 seconds. When charging starts, thegreen LED light in the charging socket willbegin to flash. The approximate remainingcharging time or the charging status willbe displayed in the instrument panel. Charging may be temporarily interrupted if the vehicle is unlocked:
and a door is open
‒ charging will
restart within a few minutes.
if no door is opened
‒ the vehicle will
automatically relock. Charging willresume after 1 minute.
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 insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
During charging, condensation from the air conditioning may form under the vehicle. Thisis normal and is caused by the hybrid batterycooling.

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 todetect for children, pedestrians, cyclists oranimals. This is particularly true at lowspeeds, e.g. in parking lots.
WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and thecombustion engine switched off. Theengine will start automatically if the chargelevel in the hybrid battery is low and theresulting exhaust gases can be very harm-ful to people and animals.
Hybrid
This is the default mode in which the elec- tric motor and combustion engine work together.
The vehicle starts in
Hybrid mode. The control
system uses both the electric motor and the gasoline engine – separately or in tandem –and adapts utilization with regard to perform-ance, fuel consumption and comfort. At highspeeds, ground clearance is automatically lowered 7
to reduce air resistance. Driving capacity on the electric motor alone is deter- mined by factors such as the hybrid battery'scharge level, the need for heat or cooling inthe passenger compartment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power.When the accelerator pedal is pressed, onlythe electric motor will be activated until thebattery reaches a certain charge level. Abovethis level, the current in the battery cannotsupply the power requested by the acceleratorpedal and the combustion engine will start. When the hybrid battery's charge level is low, the combustion engine will start more fre-quently to save the remaining current in thebattery. Charge the hybrid battery from a120-240 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 consumption with a mix between the electricmotor and gasoline engine, without compro-mising on climate comfort or driving experi-ence. When faster acceleration is requestedby the driver, the electric driveline will be uti-lized to help provide maximum additionalpower. The vehicle also monitors the driving condi- tions and automatically engages all-wheeldrive if necessary. All-wheel drive and extra electric power are always available regardlessof the battery's charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will be displayed in the instrument panel. Thegauge will indicate the amount of electricalcurrent required when the driver depressesthe accelerator pedal. The marker between thelightning and the drop shows how much cur-rent is available.
The instrument panel gauge when both the electric motor and the combustion engine are being used.
The instrument panel also shows how much current is being restoredto the battery (regenerated) duringlight braking.

TOP TIER Detergent GasolineVolvo endorses the use of "TOP TIER Deter- gent Gasoline" where available to help main-tain engine performance and reliability. TOPTIER Detergent Gasoline meets a new stand-ard jointly established by leading automotivemanufactures to meet the needs of today'sadvanced engines. Qualifying gasoline retail-ers (stations) will, in most cases, identify theirgasoline as having met the "TOP TIER Deter-gent Gasoline" standards.
NOTE
Information about TOP TIER Detergent Gasoline is available atwww.toptiergas.com.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticea-ble.
Fuel FormulationsDo not use gasoline that contains lead or man- ganese as a knock inhibitor, and do not use lead additives. Besides damaging the exhaust emission control systems on your vehicle, leadhas been strongly linked to certain forms ofcancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, takeprecautions. These may include:
standing upwind away from the filler noz-zle while refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouthof the filler neck during refueling
wearing neoprene gloves while handling afuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze dur-ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.
