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.

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. Acharging post that is not always active, forexample because of a timer, can cause lossof function for preconditioning.

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.

HYBRID INFORMATION
3882. The charging cable handle will lock into
place and charging will begin within 5 seconds. When charging starts, thegreen LED light in the charging socket willbegin to flash. The approximate remainingcharging time or the charging status willbe displayed in the instrument panel. Charging may be temporarily interrupted if the vehicle is unlocked:
and a door is open
‒ charging will
restart within a few minutes.
if no door is opened
‒ the vehicle will
automatically relock. Charging willresume after 1 minute.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
During charging, condensation from the air conditioning may form under the vehicle. Thisis normal and is caused by the hybrid batterycooling.

If the LED indi-cator light is not illuminated, check to makesure the cable is securely connected in thewall outlet and in the outlet in the vehicle. Awhite, red or yellow light illuminates when thepassenger compartment lighting is activatedand will remain illuminated for a short timeafter the passenger compartment lighting hasgone out.

STARTING AND DRIVING
418
Drive systemsVolvo Twin Engine combines a combustion engine for the front wheels and an electricmotor for the rear wheels.
Two drive systemsDepending on the selected drive mode and power available in the electric motor, the drivesystems can either be used separately or intandem. The electric motor gets its energy from a hybrid battery located under the tunnel con-sole. The hybrid can be charged from a walloutlet or in a special charging station. Thecombustion engine can also charge the hybridbattery using a special high-voltage generator. Both the combustion engine and the electric motor can generate power directly to thewheels. An advanced control system coordi-nates both the drive systems to help optimizedriving economy.
Hybrid battery - The hybrid battery's func- tion is to store electrical current. Thisenergy is provided by plugging the charg-ing cable into an electrical outlet, throughregenerative braking or from the high-volt-age generator. This provides current topower the electric motor and to temporar-ily power the electrical air conditioning toprecondition the passenger compartment.
Combustion engine - The combustion engine starts when the charge level in thehybrid battery is too low to provide thepower output requested by the driver.
High-voltage generator 6
- Charges the
hybrid battery. Starter for the combustion engine. Can provide the combustion engine with extra electrical current.
Electric motor - Powers the vehicle using electricity. Can provide extra torque andpower during acceleration. Provides elec-trical all-wheel drive functionality. Regen-erates braking energy into electrical cur-rent.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. To help achieve the greatest distance with the lowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging it into an electrical outlet. Make it a habit toalways begin trips with the hybrid batteryfully charged.
Locate charging stations along your route.
If possible, choose parking spots withcharging stations.
NOTE
Charge the vehicle from the electricity grid as often as possible!
Preconditioning
Whenever possible, precondition the vehi- cle before driving by connecting thecharging cable to an electrical outlet.
Avoid parking the vehicle somewherewhere the interior will become too hot ortoo cold while the vehicle is parked. If pos- sible, park the vehicle in a climate-con-trolled garage.
During a short drive after passenger com-partment preconditioning, turn off thepassenger compartment fan or the airconditioning in a hot climate.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe hybrid battery.

If the vehicle begins to overheat, the airconditioning may be temporarily switchedoff.
After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.
NOTE
It is normal for the engine's cooling fan to operate for a short time after the engine isswitched off.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).
