Automatic transmission
In vehicles with an automatic transmission, the system selects the gear so that drivingwill be as energy-efficient as possible. Thetransmission also has a manual mode.
Overview of gear selector and gear shift pattern in the instrument panel
The instrument panel shows which gear is cur- rently in use: R , N , D or B. P position is electric.
For manual shifting, the gear indicator in the instrument panel displays the gear currentlybeing used.
CAUTION
Check the operating temperature of the transmission to help avoid damage to anyof the drive system components. If there isa risk of overheating, a warning symbol willappear in the instrument panel and a textmessage will be displayed. Follow the rec-ommendations given.
Symbols in the instrument panelIf a problem should occur with the transmis- sion, a symbol and a message will appear inthe instrument panel.

Starting and stopping the combustion engine in Twin Enginevehicles An advanced control system determines the distance that the vehicle can be driven on thecombustion engine, electric motor, or both atthe same time. When driving on only theelectric motor, the vehicle may automaticallystart the combustion engine due to outsidecircumstances, e.g. low ambient tempera-tures. This is completely normal. The com-bustion engine will also always start whenthe hybrid battery is nearly fully discharged.
Climate settings at low temperaturesAt low ambient temperatures, the combustion engine will sometimes start automatically tohelp achieve the desired passenger compart-ment temperature and air quality. The amountof time the combustion engine is running canbe affected by lowering the temperature
reducing blower speed
activating
Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the electric motor's driving range and power maybe reduced and affect how often the combus-tion engine automatically starts.
Emission control systemTo help ensure that the emission control sys-tem is as energy-efficient as possible, thecombustion engine will run for several minutesafter it is started. The amount of time the com-bustion engine needs to be used variesdepending on the temperature of the three-way catalytic converter.

426 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.

Driving
Choose the Pure drive mode to help mini-
mize electric power consumption.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. This drive mode has thelowest power consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustionengine, especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will helprecharge the hybrid battery. A regenerativefunction is integrated in the brake pedaland can be augmented by the electricmotor's braking capacity when the gearselector is in mode
B.
Higher speeds increase energy consump-tion - air resistance increases with speed.
Activate the
Hold function in the Function
view at high speeds when traveling farther than is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the
Charge function to charge the hybrid bat-
tery. Charging the battery using the com- bustion engine increases fuel consump- tion and carbon dioxide emissions.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for adviceon suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal.Use the brakes instead.

Factors affecting electric motor range
A number of factors affect the electric motor's driving range. The ability to achieve along driving range varies according to theoutside conditions and to how the vehicle isdriven.
The certified value for the distance that can be driven using the electric motor should not beconsidered an expected driving range. Theactual range is dependent on a number of fac-tors.
Factors affecting driving rangeThe driver can influence some factors affectingdriving range, but not all. The longest range is achieved under very favorable conditions when all factors positivelyinfluence range.

Trailer Stability Assist *
Trailer Stability Assist (TSA 16
) is a function
designed to help stabilize a vehicle that is towing a trailer when the vehicle and trailerhave begun to sway. The function is part of the Electronic Stability Control system ESC 17
.
Reasons for swayingA vehicle towing a trailer may begin to sway for various reasons. Normally this only occursat high speeds. However, if the trailer is over-loaded or unevenly distributed, e.g. too farback, there is a risk of swaying even at lowspeeds. Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden, strong crosswind.
The vehicle and trailer are traveling on anuneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicleand trailer difficult to control and there is a riskof swerving into oncoming traffic or driving offthe road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitorsthe vehicle's movements, particularly lateral movements. If swaying is detected, the brakesare applied individually on the front wheels,which has a stabilizing effect on the vehicleand trailer. This is often enough to enable thedriver to regain control of the vehicle. If the Trailer Stability Assist function's first attempt is not adequate to stop the swayingmotion, the brakes are applied on all wheelsand engine power is temporarily reduced. Asthe swaying motion begins to decrease andthe vehicle and trailer have once againbecome stable, TSA stops regulating thebrakes/engine power and the driver regainscontrol of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the driver selects the sport mode by deactivat- ing
ESC in the center display's menu sys-
tem.
Trailer Stability Assist may not intervene if the driver tries to compensate for the swayingmotion by moving the steering wheel rapidly,because the system will then not be able todetermine if it is the trailer or the driver caus-ing the swaying. When Trailer Stability Assistis activated, the ESC symbolis displayed in the instrumentpanel.

Limitations
Main channel vs. sub-channels (FM only)
: The main channel is the only chan-
nel that can receive in hybrid mode (bothdigital and analog). If a frequency has sub-channels, they are broadcast in digitalmode only. The main FM channel will bedisplayed as, for example, "WRIF-FMHD1". The sub-FM channels will be dis-played as"WRIF-FM HD2", "WRIF-FMHD3", etc.
Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, likeall radio transmission technology, terrain,time of day, vegetation and buildings canhave a positive or negative effect on radioreception.
Analog to digital/digital to analogblending
: Analog to digital blending will
occur as the signal strength reaches a pre-set threshold in the receiver. This will benoticeable in fringe areas (areas with weakreception) and is normal.
NOTE
There may be a noticeable difference in sound quality when a change from ana-logue to digital or digital to analogueoccurs, such as:
Volume increase or decrease
Equalizer settings, i.e., Bass/ Mid-range/Treble cut or boost
Time alignment (Digital program mate-rial in extreme cases can be as muchas 8 seconds behind the analogue).This will noticeable as a "stuttering"effect.
The above items are dependant on thebroadcaster's equipment settings anddo not indicate a fault in the vehicle'sradio receiver or antenna systems .
