Pure
Uses the electric motor only, with the low- est possible energy consumption and car-bon dioxide emissions.
This drive mode prioritizes the use of the hybrid battery. Ground clearance is lowered 7
to reduce air resistance and certain climate system functions are reduced to provide thelongest possible driving distance using onlyelectricity.
Pure mode is available when the hybrid bat-
tery is sufficiently charged. Even in Puremode, the combustion engine will start if the charge level in the battery gets too low. Thecombustion engine will also start
if the vehicle's speed goes above125 km/h (78 mph)
if the driver requests more power than theelectric motor can provide
if factors such as cold weather affect thesystem or components.
This drive mode is adapted for the longestpossible driving distance with electric propul-sion and is primarily intended for use in city driving.
Pure helps provide the lowest possi-
ble consumption even when the hybrid battery is fully discharged. ECO climate is activated tocontrol the climate in the passenger compart-ment, and in slippery road conditions slightly more wheel spin may be permitted before all-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically
activated in the passenger compartment to help reduce energy consumption.
NOTE
When the Pure drive mode is activated,
settings for certain climate system and electricity consuming functions arereduced. Some of these settings can bereset manually, but full functionality will only be restored by leaving
Pure mode or
adapting the Individual drive mode to full
climate system functionality.
If condensation forms on the windows, tap the max defroster button, which will function nor-mally.
Off Road
Prioritizes the vehicle's ability to traverse difficult terrain or poor roads.
In this mode, ground clearance 7
is high, steer-
ing is light, and all-wheel drive and HillDescent Control are activated. This drive mode is only available at low speeds, up to 40 km/h (25 mph). If this speed is exceeded,
Off Road mode will be cancelled
and Constant AWD mode will be activated
instead. All-wheel drive requires both the combustion and electric motor to be in continuous opera-tion, which results in higher fuel consumption. In
Off Road mode, a compass will be dis-
played between the speedometer and the tachometer in the instrument panel. The per-missible speed range will be shown in thespeedometer.

436 This drive mode is adapted for optimal control when driving at low speeds on very poor roads or difficult terrain. It raises the chassis
7
,
reduces driveline throttle response, and locks the vehicle in all-wheel drive. The Hill DescentControl function facilitates controlled drivingon steep downgrades.
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
the engine was switched off, the suspen- sion will lower when the engine is restar-ted.
CAUTION
Do not use the Off Road drive mode when
towing a trailer without an electrical con- nection. This could result in damage to thepneumatic suspension system's bellows.
Constant AWD
Improves the vehicle's traction and han- dling by increasing all-wheel drive. This drive mode locks the vehicle in all-wheeldrive. An adapted distribution between frontand rear axle torque provides effective control,stability and traction, e.g. on slippery roads orwhen towing a heavy trailer or another vehicle. The
Constant AWD drive mode is always
available regardless of the hybrid battery's charge status. Both the combustion engine and the electric motor 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 driveaccording to the road surface, and can acti-vate the electric motor or start the combustionengine as needed.
Power
The vehicle gets sportier driving characte- ristics and a faster acceleration response.
This drive mode adapts the combined powerfrom the combustion engine and the electricmotor by providing power to both the frontand rear wheels. Gear shifting will be fasterand more distinct and the transmission willprioritize gears with a higher traction force.Steering response is faster, suspension is stiffer and ground clearance is lower 7
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 adapted for optimal per- formance and response during acceleration. Itchanges the throttle response, gear shiftingprogram and turbo boost system. Chassis set-tings and steering and brake response are also optimized. The
Power drive mode is always
available regardless of the hybrid battery's charge status.
Power mode is also available in a Polestar
Engineered* version.

Using the electric or combustion engine
An advanced control system determines the distance that the vehicle can be driven on thecombustion engine, electric motor, or both atthe same time. Its primary function is to use the motor/engine and the current available in the hybrid batteryas efficiently as possible based on the charac-teristics of the various drive modes and thepower output requested by the driver bypressing the accelerator pedal. In certain cases, temporary limitations in the system or mandatory functions to help main- tain a low overall emissions level may result in greater use of the combustion engine.

Keep in mind that not all drive modes are available in all situations. To change drive mode:
1. Press the
DRIVE MODE control.
> A pop-up menu will appear in the cen- ter display.
2. Roll the wheel upward or downward to the desired drive mode. 3. Press the drive mode control or tap its
button in the center display to confirm the selection.

Leveling control * and suspension
The vehicle's leveling control system adjusts the suspension and shock absorbers auto-matically to help optimize comfort and con-trol while driving. Leveling can also be con-trolled manually to facilitate loading or get-ting in and out of the vehicle.
Pneumatic suspension and shock absorbers
The system is adapted to the selected drive mode and vehicle speed. The pneumatic sus-pension reduces the vehicle's ground clear-ance at higher speeds to reduce air resistanceand increase stability. The shock absorbers arenormally set to help optimize comfort and areadjusted continuously according to the roadsurface and the vehicle's acceleration, brakingand cornering. The instrument panel indi-cates when the suspensionlevel is being adjusted.
The following apply if a door or the tailgate is opened:
If a door is opened, the level can only be adjusted upwards.
If the tailgate is open, the level can only beadjusted downwards.
ParkingWhen parking, make sure that there is ade-quate space above and below the vehiclesince ground clearance may vary depending on e.g. ambient temperature, how the vehicleis loaded, if loading mode is used, which drivemode is selected after the engine is started,etc. The level may also be adjusted a period after the vehicle is parked. This is to compensatefor any height changes that may occur due totemperature changes in the air springs whenthe vehicle cools.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspensionmay occur during transport, which couldadversely affect the lashing and result in dam-age.

Low Speed Control
The low-speed function (LSC 10
) facilitates
and improves control and traction on rough roads and slippery surfaces, e.g. when towinga trailer on grass or up boat ramps. The function is included in the
Off Road drive
mode.
Low Speed Control is designed for driving on rough roads and when towing trailers at lowspeeds, up to approximately 40 km/h (25mph). When driving at low speeds, LSC prioritizes low gears and all-wheel drive to help avoidwheel spin and improve traction on all wheels.The accelerator pedal will be less responsiveto improve traction and speed control at lowspeeds. The function is activated together with Hill Descent Control (HDC 11
), which makes it pos-
sible to control speed going down steep hills using the accelerator pedal and reduces theneed to use the brake pedal. The systemmakes it possible to maintain a low and uni-form speed when driving down steep hills.
