NOTE
When the remote key is placed in the backupreader, make sure that no other vehicle keys,metal objects or electronic devices (e.g. cellu-lar phones, tablets, laptops or chargers) are inthe backup reader. Multiple vehicle keys closeto each other in the backup reader can dis-rupt their functionality.
If Vehicle start System check, wait is dis-played in the instrument panel while attemptingto start the vehicle, wait until the message disap-pears and try again to start the vehicle.

CAUTION
If the engine has not responded after 3attempts – wait for 3 minutes before startinga new attempt. Starting capability increases ifthe starter battery is given time to recover.

NOTE
The vehicle cannot be started if the hybridbattery is discharged.
WARNING
Never remove the remote control key fromthe vehicle while driving.

WARNING
Always remove the remote key from thepassenger compartment when you leavethe vehicle and make sure the ignition isin mode 0.
Always put the gear selector in P andapply the parking brake before leavingthe vehicle. Never leave the vehicle unsu-pervised while the engine is running.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by the vehi-cle contain carbon monoxide, which isinvisible and odorless but very toxic.

NOTE
With a cold start, idling speed may be consid-erably higher than normal for certain enginetypes. This is done to get the emissions sys-tem up to normal operating temperature asquickly as possible, which minimizes exhaustemissions and protects the environment.

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.

Symbols in the instrument panel
If a problem should occur with the transmission, asymbol and a message will appear in the instru-ment panel.
Symbol Meaning
Information and messages relatedto the transmission. Follow the rec-ommendations provided.
Hot or overheated transmission.Follow the recommendations provi-ded.
Reduced performance/Acceler-ation performance reduced
In the event of a temporary fault inthe driveline, the vehicle may gointo a "limp home" mode withreduced power output to help avoiddamage to the driveline.

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.

Brake - B
B can be selected at any time during a drive. In Bmode, the engine braking function is activatedwhen the accelerator pedal is released, whichhelps charge the hybrid battery. This offers addi-tional opportunities to recharge the hybrid bat-tery, since the battery is charged even when thebrake pedal is not depressed.
B mode in the instrument panel.
From B mode, it is possible to manually shift tolower gears. The currently selected gear (1-8) willbe displayed in the instrument panel.
Pull the gear selector backward once to shiftdown one gear.
Pull the gear selector backward again to shiftdown to lower gears.
To shift manually to a higher gear, the vehiclemust be equipped with steering wheel paddles*.

Shiftlock
The automatic transmission's shiftlock functionhelps prevent inadvertently moving the gearselector between different positions.
Automatic shiftlock
The automatic shiftlock has a separate safetysystem.

From Park - P
To move to another gear from P (Park), the brakepedal must be depressed and the ignition inmode II.

From Neutral - N
If the gear selector is in N and the vehicle hasbeen stationary for at least 3 seconds (with orwithout the engine running), the gear selector willbe locked in that position.
To move the gear selector from N to anothergear, the brake pedal must be depressed and theignition in mode II.

Messages in the instrument panel
If the gear selector is locked in position, a mes-sage will appear in the instrument panel, e.g.Gear lever Press brake pedal to activategear lever.
There is no mechanical shiftlock function.

The kickdown function
Kickdown is used when maximum acceleration isneeded, e.g. when passing.
When the accelerator pedal is depressed all theway to the floor (past the normal full acceleratorposition), the transmission will automaticallyengage kickdown, i.e. immediately shift down to alower gear.
If the accelerator pedal is released from the kick-down position, the transmission will automaticallyshift up again.

Safety function
The transmission control module is equipped witha downshift protection feature to help prevent theengine from overheating.
In some conditions, the transmission will preventdownshifting/kickdown if this would lead to suchhigh engine speed (rpm) that the engine couldbe damaged. If the driver still attempts downshift-ing or kickdown at a high rpm, nothing will hap-pen and the original gear will remain selected.
With kickdown, the vehicle can downshift one ormore steps at a time depending on the enginespeed. The vehicle upshifts when the engine rea-ches its maximum rpm to prevent engine dam-age.

Drive systems
Volvo Twin Engine combines a combustionengine for the front wheels and an electric motorfor the rear wheels.
Two drive systems
Depending on the selected drive mode andpower available in the electric motor, the drivesystems can either be used separately or in tan-dem.
The electric motor gets its energy from a hybridbattery located under the tunnel console. Thehybrid can be charged from a wall outlet or in aspecial charging station. The combustion enginecan also charge the hybrid battery using a specialhigh-voltage generator.
Both the combustion engine and the electricmotor can generate power directly to the wheels.An advanced control system coordinates both thedrive systems to help optimize driving economy.
