The driver should be aware of the following limi-tations for Park Assist Pilot:

The parking sequence is cancelled
A 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 display
When the anti-lock brakes or the Electronicstability control are engaged - e.g. when awheel loses grip on a slippery road
When speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to overheat-ing.
A message in the center display will explain whythe parking sequence was cancelled.
CAUTION
Under certain circumstances, the functionmay not be able to find parking spaces – onereason may be that the sensors are disruptedby external sound sources that emit the sameultrasonic frequencies that the system workswith.
Examples of such sources include horns, wettires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.

NOTE
Dirt, ice and snow covering the sensorsreduce their function and can make measure-ment impossible.

Driver responsibility
The driver should keep in mind that the functionis a parking aid ‒ not an infallible fully automaticsystem. The driver must always be prepared totake control and cancel a parking sequence ifnecessary.
There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for determin-ing if the space suggested by the function issuitable 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's abil-ity to accurately measure a parking space.
While searching and measuring the parkingspace, the function may be unable to detectobjects located far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle.
Use approved tires96 inflated to the correcttire pressure because this affects the func-tion's ability to provide parking assistance.
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 couldbe damaged by the curb during the parkingprocedure.
96"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

2. The charging cable handle will lock intoplace and charging will begin within5 seconds. When charging starts, the greenLED light in the charging socket will begin toflash. The approximate remaining chargingtime or the charging status will be displayedin the instrument panel.
Charging may be temporarily interrupted ifthe vehicle is unlocked:
and a door is open ‒ charging will restartwithin a few minutes.
if no door is opened ‒ the vehicle willautomatically relock. Charging will resumeafter 1 minute.

CAUTION
Never detach the charging cable from the120/240 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.
During charging, condensation from the air con-ditioning may form under the vehicle. This is nor-mal and is caused by the hybrid battery cooling.

Hybrid
This is the default mode in which the electricmotor and combustion engine work together.
The vehicle starts in Hybrid mode. The controlsystem 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. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat or cooling in thepassenger compartment, etc.
If there is sufficient charge in the battery, it ispossible 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, thecombustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outletusing a charging cable, or activate Charge inFunction view to reset the option of only usingthe 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.
The vehicle also monitors the driving conditionsand automatically engages all-wheel drive if nec-essary. All-wheel drive and extra electric powerare always available regardless of the battery'scharging status.

Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge willbe displayed in the instrument panel. The gaugewill indicate the amount of electrical currentrequired when the driver depresses the accelera-tor pedal. The marker between the lightning andthe drop shows how much current is available.
The instrument panel gauge when both the electricmotor and the combustion engine are being used.
The instrument panel also shows howmuch current is being restored to thebattery (regenerated) during light brak-ing.
Pure
Uses the electric motor only, with the lowestpossible energy consumption and carbondioxide emissions.
This drive mode maximizes the use of the hybridbattery. Certain climate system functions arereduced to provide the longest distance usingonly electricity.
Pure mode is available when the hybrid battery issufficiently charged. Even in Pure mode, thecombustion engine will start if the charge level inthe battery gets too low. The combustion enginewill also start
if the vehicle's speed goes above 125 km/h(78 mph)
if the driver requests more power than theelectric motor can provide
if factors such as cold weather affect thesystem or components.

Use of Additives
With the exception of gas line antifreeze duringwinter months, do not add solvents, thickeners, orother store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to these chemicals.

WARNING
Never carry a cell phone that is switched onwhile refueling your vehicle. If the phone rings,this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.

WARNING
Carbon monoxide is a poisonous, colorless,and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.

Demanding driving
In demanding driving conditions, such as whentowing a trailer or driving in hot weather or forprolonged periods at high altitudes, it may be agood idea to switch to a higher-octane fuel
(AKI10 91 or higher) or to switch to another
brand of gasoline in order to fully utilize the vehi-cle's engine capacity and optimize traction.

Three-way catalytic converter
Keep your engine properly tuned. Certainengine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Refilling coolant
Coolant helps keep the combustion engine atthe right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions onthe package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant.
If there is coolant under the vehicle, smoke fromthe cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.

WARNING
The coolant may be very hot. Never unscrewthe cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
