Drive modes
Drive modes affect the vehicle's driving charac- teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle's many functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode: • Steering
• Engine/transmission/all-wheel drive
• Brakes
• Pneumatic suspension
* and shock absorbers
• Instrument panel
• Climate control settings
Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
WARNING
Keep in mind that the vehicle does not emit any engine noise when using the electricmotor and may therefore be difficult to detectfor children, pedestrians, cyclists or animals.This is particularly true at low speeds, e.g. inparking lots.
WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and the com-bustion engine switched off. The engine willstart automatically if the charge level in thehybrid battery is low and the resulting exhaustgases can be very harmful to people and ani-mals.
HYBRID
• This is the default mode in which the electric motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control system uses both the electric motor and the gas-oline engine - separately or in tandem - and cal-culates optimal utilization with regard to perform-ance, fuel consumption and comfort. At highspeeds, ground clearance is automatically low- ered 4
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the need for heat/cooling in the passenger compart-ment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power. Whenthe accelerator pedal is pressed, only the electricmotor will be activated until the battery reaches acertain charge level. Above this level, the currentin the battery cannot supply the power requestedby the accelerator pedal and the combustionengine will start. When the hybrid battery's charge level is low, the combustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outlet using a charging cable, or activate
Charge in
Function view to reset the option of only using the electric motor. This drive mode is designed for low energy con- sumption with an optimized mix between theelectric motor and gasoline engine, without com-promising on climate comfort or driving experi-ence. When faster acceleration is requested bythe driver, the electric driveline will be utilized tohelp provide maximum additional power. Thevehicle also monitors the driving conditions andautomatically engages all-wheel drive if neces-sary. All-wheel drive and extra electric power arealways available regardless of the battery'scharging status.

Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will be displayed in the instrument panel. The gaugewill indicate the amount of electrical currentrequired when the driver depresses the accelera-tor pedal. The marker between the lightning andthe drop shows how much current is available.
The instrument panel gauge when both the electric motor and the combustion engine are being used.
The instrument panel also shows how much current is being restored to thebattery (regenerated) during light brak-ing.
PURE
•Uses the electric motor only, with the lowest possible energy consumption and carbon dioxide emissions. This drive mode maximizes the use of the hybrid battery. Ground clearance is lowered
4
to reduce
air resistance and certain climate system func- tions are reduced to provide the longest possibledriving distance using only electricity. Pure mode is available when the hybrid battery is sufficiently charged. Even in Pure mode, the com-bustion engine will start if the charge level in thebattery gets too low. The combustion engine willalso start
• if the vehicle's speed goes above 125 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 optimized for maximum drivingdistance with electric propulsion and is primarilyintended for use in city driving. Pure helps pro-vide the lowest possible consumption even whenthe hybrid battery is fully discharged. ECO climateis activated to control the climate in the passen-ger compartment, and in slippery road conditionsslightly more wheel spin may be permitted beforeall-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically acti- vated in the passenger compartment to helpreduce energy consumption.
NOTE
When the Pure drive mode is activated, set-
tings for certain climate system and electricity consuming functions are reduced. Some ofthese settings can be reset manually, but fullfunctionality 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 normally.

OFF ROAD
•Maximizes the vehicle's ability to traverse dif- ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill DescentControl are activated. This drive mode is only available at low speeds, up to 40 km/h (25 mph). If this speed is excee-ded, Off road mode will be cancelled and AWDmode will be activated instead. All-wheel drive requires both the combustion and electric motor to be in continuous operation,which results in higher fuel consumption. In Off road mode, a compass will be displayed between the speedometer and the tachometer inthe instrument panel. The permissible speedrange will be shown in the speedometer. This drive mode is optimized for maximum control when driving at low speeds on very poor roads or difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle in all-wheel drive. The Hill Descent Control func-tion facilitates controlled driving on steep down-grades.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 theengine was switched off, the suspension willlower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when towing a trailer without an electrical connec-tion. This could result in damage to the pneu-matic suspension system's bellows.
AWD
• Improves the vehicle's traction and handling by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possiblecontrol, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The AWD drive mode is always availableregardless of the hybrid battery's charge status. Both the combustion engine and the electricmotor 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 drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
POWER
•
Power mode is designed to provide sportier driving characteristics and a faster accelera-tion response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster, suspension is stiffer and ground clearance is lower 4
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 optimized for maximum per- formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. ThePower drive mode is always available regardlessof the hybrid battery's charge status.

Leveling control * and suspension
The vehicle's leveling control system adjusts the suspension and shock absorbers automaticallyto help provide good comfort and control whiledriving. Leveling can also be controlled manuallyto facilitate loading or getting in and out of thevehicle.
Pneumatic suspension and shock absorbers
The system is adapted to the selected drive mode and vehicle speed. The pneumatic suspen-sion reduces the vehicle's ground clearance athigher speeds to reduce air resistance andincrease stability. The shock absorbers are nor-mally set to provide the best possible comfort and are adjusted continuously according to theroad surface and the vehicle's acceleration, brak-ing and cornering.
The instrument panel indicateswhen the suspension level isbeing adjusted.The level cannot be adjusted when any of the side doors or the tailgate is open.
ParkingWhen parking, make sure that there is adequatespace above and below the vehicle since ground clearance may vary depending on e.g. ambienttemperature, how the vehicle is loaded, if loadingmode is used, which drive mode is selected afterthe engine is started, etc. The level may also be adjusted a period after the vehicle is parked. This is to compensate for anyheight changes that may occur due to tempera-ture changes in the air springs when the vehiclecools.
TransportingWhen transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing and result in damage.

Spare wheel11
The spare wheel is a Temporary spare and can be used to temporarily replace a punctured tireon one of the vehicle's regular wheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon as possi-ble. The driving characteristics of the vehicle change and ground clearance reduces when the sparewheel is used. Do not wash the vehicle in anautomatic car wash while using the TemporarySpare. The recommended tire pressure must be main- tained regardless of at which position the tempo-rary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a tem-porary replacement for a punctured tire. Itmust be replaced as soon as possible by astandard tire. Road holding and handling maybe affected with the "Temporary Spare" inuse. Do not drive faster than 80 km/h(50 mph).
