CLIMATE CONTROL
}}
* Option/accessory.207
The function utilises several systems in different cases: •
Residual heat from the engine, in a cold cli- mate, heats the passenger compartment tocomfort temperature.
• The ventilation, in a hot climate, cools thepassenger compartment to the current outertemperature.
NOTE
Climate comfort retention is switched off when the car is locked from the outside toavoid using residual heat unnecessarily. Useof the function is intended to maintain climatecomfort when driver or passengers remaininside the car.

Parking heater *
The parking heater helps the passenger com- partment reach the correct temperature beforedriving.
The parking heater is one of two subfunctions of the car's heater. The heater is fitted in the frontright-hand wheel housing.
NOTE
When the heater is running, smoke may be emitted from the right-hand front wheel hous-ing and a low hum may be heard. A tickingsound from the fuel pump may also be heardfrom the rear section of the car. This is per-fectly normal.
The parking heater starts automatically when extra heat is required if the parking climate con- trol's preconditioning * is activated.
It is then switched off automatically when the right temperature, the time of a set timer or theheater's maximum running time has beenreached. The heater's maximum running time is 40 minutes.
NOTE
Make sure there is enough fuel in the car's normal fuel tank if the heater needs to beused. Make sure that there is enough charge in the starter battery if the heater needs to be used.
IMPORTANT
Repeated use of the parking heater combined with short journeys may discharge the batteryand impair starting. If the heater is used on a regular basis, then the car should be driven for the same amountof time that the heater is used in order toensure that the car's battery is recharged withthe same amount of energy as consumed bythe parking heater. The parking heater is usedfor a maximum of 40 minutes each time.
WARNING
Do not use preconditioning if the car is equip- ped with a heater *:
• In unventilated spaces indoors. Exhaust gases are emitted if the heater starts.
• In locations with combustible or flamma-ble material nearby. Fuel, gas, long grass,sawdust, etc. may ignite.

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Limitations of the camera unit
The camera unit has certain limitations - which in turn also limits those functions that use the unit.
Impaired visionThe camera has limitations similar to the human eye, i.e. it can "see" worse in for example intensesnowfall or rain, dense fog, heavy dust stormsand snow flurries. Under such conditions, thefunctions of camera-dependent systems could besignificantly reduced or temporarily disengaged. Strong oncoming light, reflections in the carriage- way, snow or ice on the road surface, dirty roadsurfaces or unclear lane markings can also sig-nificantly reduce camera function when it is usedto scan the carriageway to detect pedestrians,cyclists, large animals and other vehicles.
Blocked unit
The marked area must be kept free from stickers, objects, shade film, etc. 13
.
The camera unit is placed inside the upper sec- tion of the windscreen together with the car'sradar unit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.
If the driver display shows this symbol with the message Windscreen
sensor Sensor blocked, see
Owner's manual, it means that the
camera and radar unit cannot detect other vehi- cles in front of the car.
The following table presents examples of possi- ble causes for a message being shown, alongwith the appropriate action:

Level control * and shock absorption
Level control and shock absorption are regula- ted automatically in the car.
With rear level control, the car maintains the same height at the rear regardless of load. Levelcontrol can also occur even after the car hasbeen parked.
Shock absorption (Four-C)The shock absorption is adapted according to theselected drive mode and according to the speedof the car. Shock absorption is normally set forthe best possible comfort and is regulated con-tinuously depending on the road surface, thecar's acceleration, braking and cornering.
Settings for level control
Deactivation of air suspension and level control
In certain cases, the function must be deacti- vated, e.g. before the car is raised with a jack *.
The difference in level created by raising the car with a jack can otherwise cause problems for theair suspension. Deactivating the function via the centre display:1. Press
Settings in the top view.
2. Press
My CarSuspension .
3. Select
Disable Leveling Control.
Change the damping level 11
Cars with active chassis (Four-C) and without the drive mode function
* can adjust the shock
absorption level via the centre display: 1. Press
Settings in the top view.
2. Tap on
My CarDrive ModeSuspension Control and select the level.
During transportDuring transport of the car on a ferry, train or truck, the car must be lashed around the tyresand not around other parts of the chassis.Changes in the air suspension may occur duringtransport, which could affect the lashing nega-tively.

All-wheel drive
*
All-wheel drive, AWD (All Wheel Drive), means that the car is driving all four wheels at the sametime, which improves traction.
To achieve the best possible traction and prevent wheel spin the motive force is distributed auto-matically to the wheels with the best grip. Thesystem continuously calculates the need for tor-que to the rear wheels, and can immediatelyredistribute up to half of the motor's torque to therear wheels. All-wheel drive also has a stabilising effect at higher speeds. Under normal driving conditions,the majority of power is transmitted to the frontwheels. When stationary, the all-wheel drive isalways engaged in preparation for maximum trac-tion during acceleration. All-wheel drive characteristics vary depending on the selected drive mode *.

IMPORTANT
Engine damage can occur if water enters the air filter. In depths greater than 25 cm, water could enter the transmission. This reduces the lubri-cating ability of the oils and shortens theservice life of these systems. Damage to any component, engine, transmis- sion, turbocharger, differential or its internalcomponents caused by flooding, hydrostaticlocking or oil shortage, is not covered by thewarranty. In the event of the engine stalling in water, do not try restart - tow the car from the water toa workshop - an authorised Volvo workshop isrecommended. Risk of engine breakdown.

Overheating in the engine and drive system
Under special conditions, for example hard driv- ing in hilly terrain and hot climate, there is a riskthat the engine and drive system may overheat -in particular with a heavy load.
• In the event of overheating, the engine's power may be limited temporarily.
• Remove any auxiliary lamps from in front ofthe grille when driving in hot climates.
• If the temperature in the engine's coolingsystem becomes too high then a warningsymbol is illuminated and the driver display shows the message
Engine temperature
High temperature Stop safely. Stop the
car in a safe way and allow the engine to run at idling speed for several minutes and cooldown.
• If the message

shown, stop the car and switch off the engine.
• In the event of overheating in the gearbox, analternative gear shift program will beselected. In addition, a built-in protectionfunction is activated that, amongst otherthings, illuminates a warning symbol and thedriver display shows the message
Transmission warm Reduce speed to
lower temperature or Transmission hot Stop safely, wait for cooling
. Follow the
recommendation given, reduce speed or stop the car in a safe way and allow the engine torun at idling speed for several minutes toenable the gearbox to cool down.
• If the car overheats, the air conditioning maybe switched off temporarily.
• Do not turn the engine off immediately youstop after a hard drive.
NOTE
It is normal for the engine's cooling fan to operate for a time after the engine has beenswitched off.

Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.
