Deactivating/reactivating PilotAssist
Pilot Assist can be temporarily put into standby mode and then reactivated.
Deactivating and putting Pilot Assist in standby mode
Note: This illustration is general and details may vary depending on model.
To temporarily deactivate Pilot Assist and put it in standby mode:
–Press the button on the steering wheel
(2).
> Pilot Assist goes into standby mode - the symbol (8) in the instrument panel changes color from WHITE to GRAY andthe set speed in the center of the speed-ometer will change from BEIGE to GRAY. ...or...
–Press the
◀ button on the steering wheel (3).
> Pilot Assist is turned off and Adaptive Cruise Control will go into active mode.
WARNING
• With Pilot Assist in standby mode, the driver must intervene and steer and regu-late both speed and distance to the vehi-cle ahead.
• If the vehicle comes too close to a vehicleahead when Pilot Assist is in standbymode, the driver is instead warned of theshort distance by the Distance Alert func-tion.
Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated and put in standby mode if:
• the brakes are applied.
• the gear selector is moved to
N
• a turn signal is used for more than 1 minute.
• the vehicle is driven faster than the setspeed for more than 1 minute
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return to the set speed when the accelerator pedal isreleased. When the turn signals are used, Pilot Assist's steering assistance will be temporarily deacti-vated. When the turn signal is switched off, steer-ing assistance will be automatically reactivated ifthe traffic lane's side markings can still bedetected.

Switching target vehicles with PilotAssist
At certain speeds, models with automatic trans-
missions and Pilot Assist can switch target vehi-cles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Pilot Assist is actively following another vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle, Pilot Assist will brake for the sta-tionary vehicle.
WARNING
When Pilot Assist follows another vehicle at speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi- cle to a stationary one – Pilot Assist will ignore the stationary vehicle and instead
accelerate to the stored speed.
• The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe target object is a stationary vehicle oranother object, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow.

Automatic braking with Pilot Assist
Pilot Assist has a special braking function in slow traffic and at a standstill.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Pilot Assist will go into standby mode and theAuto-hold brake function will activate.
–Pilot Assist can be reactivated by:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationary for no more than 5 minutes – after that timethe parking brake is applied and the functionis deactivated. The parking brake must be released before Pilot Assist can be reactivated.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.:
• in strong crosswinds
• on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – whenusing the Pilot Assist function – resulting inthe driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest sign of fati-gue, regardless of whether the DAC functionhas issued a warning or not.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".

Lane Keeping Aid
Lane Keeping Aid (LKA 107
) is designed to
actively steer the vehicle on freeways, highways and other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.
Lake Keeping Assistance steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65-200 km/h (40-125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavailable and go into standby mode. The function willbecome available again when the road becomessufficiently wide.
A camera monitors the road/traffic lane's marker lines.

If you become distracted and do not notice your vehicle starting to veer out of the lane whileanother vehicle is approaching from behind or isin your vehicle's blind spot, this sub-function canhelp provide assistance.
The function provides assistance by steering your vehi- cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of your lane while another vehicle is in your blind spot oranother vehicle is rapidly approaching in the next lane, this function can help the driver steer the vehicle back into its own lane. Even if the driver intentionally changes lanes using a turn signal without noticing another vehi- cle approaching, the function can provide assis-tance. The function is active at speeds between 60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines. After the system has automatically intervened, this text message will appear in the instrumentpanel:
•
Collision avoidance assistance –Automatic intervention
WARNING
• The "Steering assistance at risk of rear- end collision" subfunction is supplemen-tary driver support intended to improvedriving safety – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
• Pilot Assist is only activated if there is ahigh risk of collision – you must thereforenever wait for the function to intervene.
• The function is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

NOTE
Dirt, ice and snow covering the sensors reduce their function and can make measure-ment impossible.
Driver responsibilityThe driver should keep in mind that PAP is a parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take control and cancel a parking sequence if neces-sary. There are a number of things to keep in mind when parking, including:
• The driver is always responsible for determin-ing if the space suggested by PAP is suita-ble for parking.
• Do not use PAP when using snow chains ora temporary spare tire.
• Do not use PAP if there are any objects pro-truding 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, PAP may be unable to detect objectslocated far into the space.
• PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle. •
Use approved tires 128
inflated to the correct
tire pressure because this affects PAP's abil-ity to provide parking assistance.
• PAP's 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.
• Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake sure that your vehicle is parallel to rel-evant parking spaces when PAP is measur-ing the parking space.
CAUTION
Switching to another approved wheel and/or tire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.

Transmission The transmission is part of the vehicle's driveline (power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis- sion and an electric motor for rear-wheel drive.The number of gears allows the engine's torqueand power band to be effectively utilized. Two ofthe gears are overdrive gears that save fuel whendriving at a constant engine speed. The steering wheel paddles
* can be used to shift up or down
manually. The instrument panel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.

OFF ROAD
•Maximizes the vehicle's ability to traverse dif- ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill DescentControl are activated. This drive mode is only available at low speeds, up to 40 km/h (25 mph). If this speed is excee-ded, Off road mode will be cancelled and AWDmode will be activated instead. All-wheel drive requires both the combustion and electric motor to be in continuous operation,which results in higher fuel consumption. In Off road mode, a compass will be displayed between the speedometer and the tachometer inthe instrument panel. The permissible speedrange will be shown in the speedometer. This drive mode is optimized for maximum control when driving at low speeds on very poor roads or difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle in all-wheel drive. The Hill Descent Control func-tion facilitates controlled driving on steep down-grades.NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
Due to the increased ground clearance, if the OFF ROAD mode was selected when theengine was switched off, the suspension willlower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when towing a trailer without an electrical connec-tion. This could result in damage to the pneu-matic suspension system's bellows.
AWD
• Improves the vehicle's traction and handling by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possiblecontrol, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The AWD drive mode is always availableregardless of the hybrid battery's charge status. Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption. In the other drive modes, the vehicle automati- cally adapts the need for all-wheel drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
POWER
•
Power mode is designed to provide sportier driving characteristics and a faster accelera-tion response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster, suspension is stiffer and ground clearance is lower 4
to help reduce body roll when cornering.
Both the combustion engine and the electric motor are engaged to enable all-wheel drive,which results in higher fuel consumption. This drive mode is optimized for maximum per- formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. ThePower drive mode is always available regardlessof the hybrid battery's charge status.

Hill Descent Control The function for assisting when driving downhill, Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes. The function is included in the Off Road drive mode.
HDC is designed for driving on rough roads at low speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.
WARNING
HDC is only intended to be a supplementary braking aid and it does not function in all sit-uations. The driver is always ultimately responsible for operating the vehicle in a safe manner.
FunctionHill Descent Control allows the vehicle to move forward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle willreturn to very low speed regardless of how steep
