Long-term storage of vehicles with hybrid batteries To help minimize degradation of the hybrid battery if the vehicle is not driven for a pro-longed period (longer than 1 month) thehybrid battery charge level should be kept atapprox. 25% according to the gauge in theinstrument panel.
Do as follows:
1. If the hybrid battery charge level is high,drive the vehicle until the charge level is approximately 25%. If the charge level islow, charge the battery until the level rea-ches approximately 25%. 2. If the vehicle is not driven for more than 6
months or the hybrid battery's chargelevel is noticeably below the 25% mark,charge the battery to about 25% to helpcompensate for the natural battery dis-charge that occurs in long-term storage.Regularly check the charge level using thegauge in the instrument display.
NOTE
Store the vehicle in as cool a location as possible to minimize battery aging duringlong-term storage. In the summer, park thevehicle indoors or in a shady location,whichever is cooler.

Starting the vehicle
The vehicle can be started using the start knob in the tunnel console when the remotekey is in the passenger compartment.
Start knob in the tunnel console.
WARNING
Before starting:
Buckle your seat belt.
Adjust the seat, steering wheel and mirrors.
Make sure you can fully depress thebrake pedal.
The remote key is not physically used to startthe ignition because the vehicle is equippedwith the keyless Passive Start system. To start the vehicle:
CAUTION
The vehicle cannot be started if the charg- ing cable is still plugged in. Make sure topull out the charging cable from the charg-ing socket before starting the vehicle.
1. The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must be in the front section of the passen-ger compartment. With the optional key- less locking/unlocking function *, the key
can be anywhere in the vehicle.
2. Press and hold down the brake pedal 1
as
far as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the original position.
WARNING
Never use more than one inlay mat at a time on the driver's floor. If any othertype of floor mat is used, remove theoriginal mat from the driver's seat floorbefore driving. All types of mats mustbe securely anchored in the attach-ment points in the floor. Make sure thefloor mat does not impede the move-ment of the brake pedal or acceleratorpedal in any way, as this could be aserious safety hazard.
Volvo's floor mats are specially manu-factured for your vehicle. They must beproperly secured in the attachmentpoints in the floor to help ensure theycannot slide and become trappedunder the pedals.
The starter motor will crank until the enginestarts or until overheating protection is trig-gered. During normal start conditions, the vehicle's electric motor will be prioritized and the gaso-line engine will remain off. This means thatonce the start knob is turned clockwise, theelectric motor has been "started" and the vehi-cle is ready to be driven. The warning andinformation symbols in the instrument panel
1 If the vehicle is moving, it is only necessary to turn the start knob clockwise to start the engine.

will go out and the selected theme will be dis- played to indicate that the electric motor isactivated. In some situations, such as in cold weather or if the hybrid battery's charge level is too low,the gasoline engine will start instead.
Error messagesIf the Vehicle key not found message is
shown in the instrument panel at start, place the remote key at the backup reader and thenmake a new start attempt.
Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempt- ing to start the vehicle, wait until the messagedisappears and try again to start the vehicle.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
WARNING
Never remove the remote control key from
the vehicle while driving.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.

CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.
NOTE
With a cold start, idling speed may be con- siderably higher than normal for certainengine types. This is done to get the emis-sions system up to normal operating tem-perature as quickly as possible, which min-imizes exhaust emissions and protects theenvironment.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with anumber of automatic brake assist functions.These systems provide assistance by e.g. thedriver not needing to depress the brake pedalat a traffic light, when starting up a hill orwhen driving down a hill. Depending on how the vehicle is equipped, the following brake assist functions may beincluded:
Auto-hold brake function at a standstill(Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Brakes
The brake pedal is used to apply the vehicle's regular brakes, which are part of the brakesystem.
The vehicle is equipped with two brake cir- cuits. If one brake circuit is damaged, thebrake pedal will go down further whendepressed. More pressure will then berequired from the driver for normal brakingeffect.
WARNING
The power brakes only work when the electric motor or combustion engine is run-ning.
If the brake pedal is used when the engine is switched off, greater pressure must be appliedto brake the vehicle. In very hilly areas or when driving with a heavy load, gear position B can be used to augment
the brakes with engine braking. Use the Off Road drive mode to increase the engine braking effect when driving on steepdowngrades at low speeds.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking System (ABS 2
), which helps prevent
the wheels from locking and helps maintain steering control when braking. Vibrations may

418be felt from the brake pedal when ABS is operating, which is normal. After the vehicle is started, a brief test of the ABS system is automatically performed whenthe driver releases the brake pedal. An addi-tional automatic test of the system may beperformed when the vehicle is traveling at alow speed. During the test, the brake pedalmay feel as though it is pulsating.
Light braking charges the hybrid
battery
When the brakes are applied lightly, the elec-tric motor braking function is used. This con-verts the vehicle's kinetic energy into electricalenergy, which is used to charge the hybridbattery. When the battery is being chargedwith the electric motor braking function, thiswill be indicated in the instrument panel.When the battery is being charged with the electric motor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of 150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is usedto augment braking. This is indicated in theinstrument panel with the pointer down in thered area.
