Parking climate
Parking climate is an umbrella term for vari- ous functions that improve the passengercompartment climate when the vehicle isparked, e.g. preconditioning.
Parking climate functions are con- trolled from the Parking climate tab
in the center display's Climate view. Tap the symbol in the center of the
climate bar to open Climate view.

Preconditioning
Preconditioning is a climate function that, if possible, attempts to achieve a comfortabletemperature in the passenger compartmentbefore driving.
Preconditioning can be started immediately or started at a preset time using a timer. The function utilizes several of the vehicle's systems:
In cold weather, the parking heater heatsthe passenger compartment to a comfort-able temperature.
In warm weather, air conditioning coolsthe passenger compartment to a comfort-able temperature.
The electrically heated steering wheel
*
and seats * can be activated.
Heating for the windshield, rear windowand door mirrors are automatically acti-vated as needed.
During preconditioning in a hot climate, con-densation from the air conditions may dripunder the vehicle. This is normal.

* Option/accessory.225
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.

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.

HeaterThe heater has two sub-functions that help warm the passenger compartment or enginein various situations.
The heater has two sub-functions:
Parking heater - heats the passenger com- partment as needed when the parking cli-mate's preconditioning is activated.
Auxiliary heater - heats the passengercompartment and engine while driving.
The heater is a high-voltage coolant heaterand is mounted in the front right-side wheelhousing.
Battery and chargingThe heater is powered by the vehicle's hybridbattery. If the charge level in the hybrid batteryis too low, the heater will switch off automati-cally and a message will be displayed in theinstrument panel.
NOTE
Make sure that the battery has sufficient charge if the heater must be used.

The parking heater heats the passenger com- partment as needed before driving if precon-ditioning is activated.
The parking heater is one of two sub-functions of the vehicle's heater. The heater is mountedin the front right-side wheel housing. The parking heater starts automatically if the parking climate's preconditioning is activatedand the passenger compartment needs to beheated. Heater running time varies depending on fac- tors such as battery charge level, passengercompartment temperature and ambient tem-perature, but it will never run for longer than40 minutes.

Replacing the remote key's battery
The battery in the remote key must be replaced when it is discharged.
NOTE
All batteries have a limited service life and must eventually be replaced (does notapply for Key Tag). The battery's service lifevaries depending on how often thevehicle/key is used.
The remote key battery should be replaced if
the information symbol illuminates and the message

NOTE
Move closer to the vehicle and try to unlock it again.
The battery in the smaller key without but- tons 7
(the Key Tag) cannot be replaced. A new key can be ordered from an authorized Volvo workshop.
CAUTION
An end-of-life Key Tag must be turned in to an authorized Volvo workshop. The keymust be deleted from the vehicle becauseit can still be used to start the vehicle viabackup start.
Opening the key and replacing the battery
Hold the remote key with the front side

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.

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
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.
Stability control 2This function helps control the driving andbraking force of each individual wheel in anattempt to stabilize the vehicle.
Spin control and active yaw controlThis function is active at low speeds andbrakes the wheels that are spinning to transfer

Engine drag control
Engine drag control (EDC

) can help prevent
inadvertent wheel lock, e.g. after downshiftingor using engine braking when driving at lowspeeds on a slippery surface. Inadvertent wheel lock while driving could impair the driver's ability to steer the vehicle.

Electronic Stability Control in sport mode The stability system (ESC 4
) is always acti-
vated and cannot be switched off. However, the driver can select
ESC Sport Mode,
which offers more active driving characteris- tics.
With the ESC Sport Mode sub-function
selected, intervention from the system is reduced and more lateral movement is permit-ted, giving the driver more control of the vehi-cle than usual. When
ESC Sport Mode is selected, the func-
tion may seem to be disabled even though it continues to assist the driver.
ESC Sport Mode also helps provide more
traction, even if the vehicle gets stuck or is driving on a loose surface such as deep snowor loose sand.
