Activating and deactivating front seat ventilation *
The seats can be ventilated to provide increased comfort in warm weather.
The ventilation system consists of fans in the seats and backrest that draw air through theseat upholstery. The cooler the passengercompartment is, the greater the cooling effectof the ventilation. The system can be activatedwhen the engine is running.
1. Tap the left- or right-side steering wheel and seat button in the center display's cli- mate bar to open the controls for steeringwheel and seat heating. If the vehicle is not equipped with heated seats or heated steering wheel (for thedriver's side), the button for seat ventila-tion is directly accessible in the climatebar.
2. Tap the seat ventilation button repeatedly
to select one of the four levels: Off, High,Medium or Low.
> The level is changed and the set level is displayed in the button.

NOTE
Preconditioning is only available when the car is connected to an electrical outlet. Acharging post that is not always active, forexample because of a timer, can cause lossof function for preconditioning. If the vehicle is not connected to an electri- cal socket it is still possible in a warm cli-mate to achieve brief cooling of the pas-senger compartment by direct starting pre-conditioning.
NOTE
During preconditioning of the passenger compartment, the vehicle works to reach acomfortable temperature and not the tem-perature set in the climate system.

Starting and stopping preconditioning
Preconditioning heats or cools the passenger compartment, if possible, before driving. Thefunction can be started in the center displayor from a cellular phone.
Starting and stopping from the vehicle
1. Tap the symbol in the center of the climate bar to open Climate view in the center dis- play.
2. Select the
Parking climate tab.
3. Tap the boxes to select if seat/steering wheel heating should be activated along with preconditioning for each function.
4. Tap

> Preconditioning starts/stops and the button lights up/goes out.
NOTE
Preconditioning is only available when the car is connected to an electrical outlet.

NOTE
The vehicle doors and windows should be closed during preconditioning of the pas-senger compartment.
Starting from app *A device with the Volvo On Call * app can be
used to start preconditioning or check set- tings. Preconditioning heats or cools the pas-senger compartment (using the vehicle's airconditioning) to a comfortable temperature. The passenger compartment can also be pre- conditioned using the Engine Remote Start (ERS) 2
function using the Volvo On Call * app.

DRIVER SUPPORT

Driver support systems
The vehicle is equipped with a number of driver support systems that can provide thedriver with active or passive assistance in var-ious situations.
The systems can, for example, help the driver:
maintain a set speed
maintain a set time interval to the vehicle ahead
help prevent a collision by warning thedriver and applying the brakes
park the vehicle.
Some of the systems are standard and othersare options. This also varies from market tomarket.

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.

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.
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.
