Speed-dependent steering wheel resistance Speed-dependent power steering increases the steering wheel resistance in pace withthe vehicle's speed, which can help give thedriver an enhanced feeling of control and sta-bility.
Steering is stiffer on highways. When parking and at low speeds, it will be easier to movethe steering wheel.
NOTE
In rare situations, the power steering may become too hot andrequire temporary cooling – dur-ing such time the power steering
will work at reduced output and the steer-ing wheel may feel more difficult to move. The message
Power steering Assistance
temporarily reduced will be displayed
along with this symbol in the instrument panel.
While the power steering is working at reduced power, the driver support func-tions and systems with steering assistanceare not available.

Electronic Stability Control
The Electronic Stability Control (ESC 1
) func-
tion helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel whenthe system is intervening. When the system has inter- vened to apply the brakes, apulsing sound may be heard
and the vehicle may accelerate more slowlythan expected when the accelerator pedal isdepressed.
The system consists of the following sub-func- tions:
Stability control 2
Spin control and active yaw control
Engine drag control
Trailer Stability Assist
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

tively, they may be detected incorrectly as lane markings, with a subsequentrisk of contact between the vehicle andsuch obstacles. The driver is responsi-ble for ensuring that the vehicle main-tains a suitable distance from suchobstacles.
The camera and radar sensors do nothave the capacity to detect all oncom-ing objects and obstacles in trafficenvironments, e.g. potholes, stationaryobstacles or objects that completely orpartially block the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input islimited in force, which means that itcannot always help the driver to steerand keep the vehicle within the lane.
In vehicles equipped with Sensus Navigation
*, the function is able to use
information from map data, which could cause variations in performance.
Pilot Assist will be switched off if thespeed-dependent power steeringwheel resistance is working at reducedpower, e.g. during cooling due to over-heating.WARNING
Pilot Assist should only be used if there are clear lane lines painted on each side of thelane. All other use will increase the risk ofcontact with nearby obstacles that cannotbe detected by the functions.
WARNING
This is not a collision avoidance sys- tem. The driver is always responsibleand must intervene if the system failsto detect a vehicle ahead.
The function does not brake for peopleor animals and does not brake for smallvehicles, such as bikes and motorcy-cles. Similarly, it does not brake for lowtrailers, oncoming, slow-moving or sta-tionary vehicles and objects.
Do not use the function in demandingsituations, such as in city traffic, atintersections, on slippery surfaces,with a lot of water or slush on the road,in heavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
The driver can always correct or adjust steer-ing assistance provided by Pilot Assist by turn-ing the steering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be drivenon flat roads. The function may not be able tomaintain the correct time interval to the vehi-cle ahead when driving down steep hills. Thedriver should be extra attentive and preparedto apply the brakes. Do not use Pilot Assist if the vehicle is carrying a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Other limitationsThe Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

City Safety steering assistance for evasive maneuver City Safety steering assistance can help the driver steer away from a vehicle/obstaclewhen it is not possible to avoid a collision bybraking alone. City Safety steering assistanceis always activated and cannot be switchedoff.
Your vehicle swerves away
Slow-moving/stationary vehicle or obsta- cle.
City Safety helps provide assistance bystrengthening the driver's steering move-ments, but only if the driver has begun evasiveaction and the system detects that the driver'ssteering movements are not sufficient to avoida collision. The brake system is used simultaneously to further strengthen steering movements. The function also helps stabilize the vehicle after ithas passed the obstacle. City Safety steering assistance can detect:
vehicles
cyclists
pedestrians
large animals

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 104
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

"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

HYBRID INFORMATION
374
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.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with anumber of automatic brake assist functions.These systems provide assistance by e.g. thedriver not needing to depress the brake pedalat a traffic light or when starting up a hill. Depending on how the vehicle is equipped, the following brake assist functions may beincluded:
Auto-hold brake function at a standstill(Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Brakes
The brake pedal is used to apply the vehicle's regular brakes, which are part of the brakesystem.
The vehicle is equipped with two brake cir- cuits. If one brake circuit is damaged, thebrake pedal will go down further whendepressed. More pressure will then berequired from the driver for normal brakingeffect.
WARNING
The power brakes only work when the electric motor or combustion engine is run-ning.
If the brake pedal is used when the engine is switched off, greater pressure must be appliedto brake the vehicle. In very hilly areas or when driving with a heavy load, gear position B can be used to augment
the brakes with engine braking.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking System (ABS 2
), which helps prevent
the wheels from locking and helps maintain steering control when braking. Vibrations maybe felt from the brake pedal when ABS isoperating, which is normal. After the vehicle is started, a brief test of theABS system is automatically performed whenthe driver releases the brake pedal. An addi-tional automatic test of the system may beperformed when the vehicle is traveling at alow speed. During the test, the brake pedalmay feel as though it is pulsating.
Light braking charges the hybrid
battery
When the brakes are applied lightly, the elec-tric motor braking function is used. This con-verts the vehicle's kinetic energy into electricalenergy, which is used to charge the hybridbattery. When the battery is being chargedwith the electric motor braking function, thiswill be indicated in the instrument panel.
