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.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.
Gear selector and gear selector positions overview.
Change gear position by pushing the spring- loaded gear selector forward or rearward, or tothe side for manual shifting.
Gear selector positions
Park - P
Gear selector and P position overview
Park is activated using the P button located
next to the gear selector. In P mode, the transmission is mechanically
locked.Select P when the vehicle is parked or when
starting the engine. The vehicle must be sta- tionary when Park is selected. To move to another gear from Park, the brake pedal must be depressed and the ignition inmode II.
When parking – apply the parking brake before shifting to Park.
WARNING
Always apply the parking brake when park- ing on an incline. Selecting a gear or put-ting the automatic transmission in P may
not be sufficient to keep the vehicle sta-tionary in all situations.
NOTE
The gear selector must be in position P in
order to lock the vehicle and set the alarm.
Help functions The system will automatically shift to P
if the ignition is switched off while
D or R
is selected.
if the driver unbuckles the seat belt and opens the driver's door while the vehicle isrunning with the gear selector in a gearother than
P.
To park a vehicle with an unbuckled seat beltand open door – end P mode by shifting to R
or D again.
The system will not automatically shift to P if
the ignition is switched off while the gearselector is in the neutral position (N). This is tomake it possible to wash the vehicle in anautomatic car wash in which the vehicle ispulled forward on rolling wheels.

No gear is selected and the engine can be started. Apply the parking brake if the vehicleis stationary with the gear selector in N.
To move the gear selector from N to another
gear, the brake pedal must be depressed andthe ignition in mode II.
D drive mode
D is the normal driving gear position. The
transmission shifts up or down automatically depending on acceleration and speed. The vehicle must be stationary when the gear selector is moved from R to D.
Brake - B
Brake position in instrument panel overview.
From the B position, it is possible to shift
manually. B can be selected at any time while
driving. When the accelerator pedal is released, the electric motor brakes the vehicleand the hybrid battery is recharged at thesame time. This offers additional opportunitiesto recharge the hybrid battery, since the bat-tery is charged even when the brake pedal isnot depressed. Select brake by moving the gear selector rear- ward from the D position. The currently
selected gear will be displayed in the instru-ment panel.
Push the gear selector to the right toward"
+ " (plus) and release to shift up one gear.
Push the gear selector to the left toward"
– " (minus) and release to shift down one
gear.
Push the gear selector rearward to returnto
D mode.
For smooth shifting and engine performance,the transmission will shift down automaticallyif the vehicle's speed becomes too low for theselected gear.

The kickdown function Kickdown can be used when maximum acceleration is needed, e.g. when passing.
When the accelerator pedal is depressed all the way to the floor (past the normal full accel-erator position), the transmission will auto-matically engage kickdown, i.e. immediatelyshift down to a lower gear. If the accelerator pedal is released from the kickdown position, the transmission will auto-matically shift up again.
Safety function
The transmission control module is equipped with a downshift protection feature to helpprevent the engine from overheating. In some conditions, the transmission will pre- vent downshifting/kickdown if this would leadto such high engine speed (rpm) that theengine could be damaged. If the driver stillattempts downshifting or kickdown at a highrpm, nothing will happen and the original gearwill remain selected. With kickdown, the vehicle can downshift one or more steps at a time depending on theengine speed. The vehicle upshifts when theengine reaches its maximum rpm to preventengine damage.

All Wheel Drive (AWD)
All-wheel drive (AWD 5
), also called four-
wheel drive, means that power is distributed to all four wheels, which improves traction.
The electric motor that powers the rear wheels enables electronic all-wheel drive functionality.All-wheel drive reacts differently depending onwhich drive mode is selected.

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.

NOTE
Extreme weather conditions, towing a trailer, high altitude and lower fuel gradethan recommended are factors that cansignificantly increase the vehicle's fuel con-sumption.
Trailer weights
WARNING
Please adhere to the recommendations provided for trailer weight. If the recom-mendations are not followed, the vehicleand trailer may be difficult to control duringevasive maneuvers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictionson trailer weight and speed. The trailerhitches may be certified for higher towingweights than the vehicle is permitted totow.
Self-leveling suspension *The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardlessof load (up to the maximum permitted weight).When the vehicle is stationary, the rear end of the vehicle will be slightly lowered, which isnormal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of over-heating when driving with a trailer. If overheat-ing of the engine and drive system is detected,a warning symbol will illuminate in the instru-ment panel and a message will appear. The automatic transmission selects the opti- mal gear for the current load and enginespeed.
