Transmission
The transmission is part of the vehicle's driveline(power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis-sion and an electric motor for rear-wheel drive.The number of gears allows the engine's torqueand power band to be effectively utilized. Two ofthe gears are overdrive gears that save fuel whendriving at a constant engine speed. The steeringwheel paddles* can be used to shift up or downmanually. The instrument panel shows the gearcurrently in use.

CAUTION
Check the operating temperature of thetransmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.

Gear selector positions forautomatic transmissions
In vehicles with an automatic transmission, thesystem selects the optimal gear for the currentdriving conditions. The transmission also has amanual mode.
The instrument panel shows which gear is cur-rently in use:
P, R, N, D or B.
For manual shifting, the gear indicator in theinstrument panel displays the gear currentlybeing used (1-8).

Selecting gears
The gear selector is a shift-by-wire selector,where shifting is done electronically instead ofmechanically. This makes shifting easier and thegear positions more distinct.
Select gears by moving the spring-loaded, non-locking gear selector forward or backward.
Gear selector positions
Park - P
Park is activated using the P button located nextto the gear selector.
Select P when the vehicle is parked or when star-ting the engine. The vehicle must be stationarywhen Park is selected.
To move to another gear from Park, the brakepedal must be depressed and the ignition inmode II.
When parking – apply the parking brake beforeshifting to Park.
WARNING
Always apply the parking brake when parkingon an incline. Selecting a gear or putting theautomatic transmission in P may not be suffi-cient to keep the vehicle stationary in all sit-uations.

NOTE
The gear selector must be in the P positionbefore the vehicle can be locked and thealarm set.

Starting and stopping thecombustion engine in Twin Enginevehicles
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time. When driving on only the electricmotor, the vehicle may automatically start thecombustion engine due to outside circumstan-ces, e.g. low ambient temperatures. This is com-pletely normal. The combustion engine will alsoalways start when the hybrid battery is nearlyfully discharged.

Climate settings at low temperatures
At low ambient temperatures, the combustionengine will sometimes start automatically to helpachieve the desired passenger compartmenttemperature and air quality. The amount of timethe combustion engine is running can be affec-ted 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, theelectric motor's driving range and power may bereduced and affect how often the combustionengine automatically starts.
Emission control system
To help ensure that the emission control systemfunctions optimally, the combustion engine willrun for several minutes after it is started. Theamount of time the combustion engine needs tobe used varies depending on the temperature ofthe three-way catalytic converter.

Available drive modes
WARNING
Keep in mind that the vehicle does not emitany 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 unventilatedarea 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 electricmotor and combustion engine work together.
The vehicle starts in Hybrid mode. The controlsystem 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-
ered3 to reduce air resistance. Driving capacity onthe electric motor alone is determined by factors
such as the hybrid battery's charge level, theneed for heat/cooling in the passenger compart-ment, etc.
If there is sufficient charge in the battery, it ispossible 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, thecombustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outletusing a charging cable, or activate Charge inFunction view to reset the option of only usingthe 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 willbe 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 electricmotor and the combustion engine are being used.
The instrument panel also shows howmuch current is being restored to thebattery (regenerated) during light brak-ing.

Hill Descent Control
The function for assisting when driving downhill,Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes.
The function is included in the Off Road drivemode.
HDC is designed for driving on rough roads atlow speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.

WARNING
HDC is only intended to be a supplementarybraking aid and it does not function in all sit-uations.
The driver is always ultimately responsible foroperating the vehicle in a safe manner.

Function
Hill Descent Control allows the vehicle to moveforward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle willreturn to very low speed regardless of how steep
the hill is and without the brakes needing to beapplied. The brake lights will illuminate when thefunction is activated.
The driver can brake to stop or slow the vehicleat any time by depressing the brake pedal.
HDC is activated along with Low Speed Control(LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
HDC can be used in gear positions D and R,and in manual gears 1 or 2.
It is not possible to manually shift to thirdgear or higher when HDC is active.

NOTE
When LSC with HDC is activated in the OFFROAD drive mode, the feel of the acceleratorpedal and engine response will change.

NOTE
This drive mode is not designed to be usedfor normal street driving.
NOTE
The function is deactivated when driving athigh speeds and must be reactivated at lowerspeeds if so desired.

Fuel (p. 472)
Fuel
Volvo recommends the use of detergent gaso-line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.

NOTE
Volvo recommends not using external fuelinjector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.

Unleaded fuel
All Volvo vehicles have a three-way catalytic con-verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of
the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain anoctane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.

Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing"oxygenates" which are usually alcohols orethers. In some areas, state or local laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel.

NOTE
When switching to higher octane fuel orchanging gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticeable.

Fuel Formulations
Do not use gasoline that contains lead or manga-nese as a knock inhibitor, and do not use leadadditives. Besides damaging the exhaust emis-sion control systems on your vehicle, lead hasbeen strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, take pre-cautions. These may include:
standing upwind away from the filler nozzlewhile refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouth ofthe filler neck during refueling
wearing neoprene gloves while handling afuel filler nozzle.

Use of Additives
With the exception of gas line antifreeze duringwinter months, do not add solvents, thickeners, or
other store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to these chemicals.
WARNING
Never carry a cell phone that is switched onwhile refueling your vehicle. If the phone rings,this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.

WARNING
Carbon monoxide is a poisonous, colorless,and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.

Demanding driving
In demanding driving conditions, such as whentowing a trailer or driving in hot weather or forprolonged periods at high altitudes, it may be a
good idea to switch to a higher-octane fuel (AKI6
91 or higher) or to switch to another brand ofgasoline in order to fully utilize the vehicle'sengine capacity and optimize traction.

Emission controls

Three-way catalytic converter
Keep your engine properly tuned. Certainengine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.
