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 or when starting up 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.
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 maybe felt from the brake pedal when ABS isoperating, which is normal. After the vehicle is started, a brief test of theABS 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.

WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.

Brakes (p. 403)
Braking on wet roads
Prolonged driving in heavy rain without brak- ing may cause braking effect to be slightlydelayed the first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pres-sure to the brake pedal. You should thereforemaintain a greater distance to the vehicleahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helpswarm up the brake discs, enabling them to drymore quickly and protecting them against cor-rosion. Consider the current traffic situationwhen braking.

Auto-hold brakes
With the Auto-hold brake function, the driver can release the brake pedal and the brakeswill remain applied, for example, when thevehicle has stopped at a traffic light or inter-section.
When the vehicle stops, the brakes are acti- vated automatically. The function can useeither the normal brakes or the parking brakesto keep the vehicle stationary and works onflat surfaces or hills. If the driver has their seatbelt fastened or if the driver's door is closed,the brakes will disengage automatically whenthe vehicle starts driving.
NOTE
When braking to a stop on an uphill or downhill gradient, depress the brake pedalwith slightly more force than usual beforereleasing to ensure that the vehicle cannotmove at all.
The parking brake is activated if
the vehicle is switched off
the driver's door is opened
the driver's seat belt is removed
the vehicle has been stationary for a pro- longed period of time (5-10 minutes)

Activating and deactivating Auto- hold at a standstill
The Auto-hold brake function at a standstill is activated with the button in the tunnel con-sole.
–Press the button in the tunnel console to activate or deactivate the function.
> The indicator light in the button will illu- minate when the function is activated. The function will remain active the nexttime the vehicle is started.
When shutting offIf the function is active and holdingthe vehicle stationary using the nor-mal brakes (A symbol lit in theinstrument panel), the brake pedal
must be depressed while pressing the buttonin order to deactivate Auto-hold.
The function will remain off until it is reac- tivated.
When Auto-hold is switched off, Hill StartAssist (HSA) will remain active to helpprevent the vehicle from rolling backwardwhen starting up a hill.

Hill Start Assist
The function for assisting when starting the vehicle on inclines (HSA 4
) helps prevent the
vehicle from rolling backward when starting on an uphill gradient. When backing up a hill,HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brake pedal in the brake system for several secondsafter the brake pedal has been released. This temporary braking effect is released after a few seconds or when the driver begins driv-ing. Hill Start Assist is available even when the Auto-hold brake function is switched off.

WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and thecombustion engine switched off. Theengine will start automatically if the chargelevel in the hybrid battery is low and theresulting exhaust gases can be very harm-ful to people and animals.
Hybrid
This is the default mode in which the elec- tric motor and combustion engine worktogether.
The vehicle starts in
Hybrid mode. The control
system uses both the electric motor and the gasoline engine – separately or in tandem –and adapts utilization with regard to perform-ance, fuel consumption and comfort. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat or cooling inthe passenger compartment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power.When the accelerator pedal is pressed, onlythe electric motor will be activated until thebattery reaches a certain charge level. Abovethis level, the current in the battery cannotsupply the power requested by the acceleratorpedal and the combustion engine will start. When the hybrid battery's charge level is low, the combustion engine will start more fre- quently to save the remaining current in thebattery. Charge the hybrid battery from a120-240 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 consumption with a mix between the electricmotor and gasoline engine, without compro-mising on climate comfort or driving experi-ence. When faster acceleration is requestedby the driver, the electric driveline will be uti-lized to help provide maximum additionalpower. The vehicle also monitors the driving condi- tions and automatically engages all-wheeldrive if necessary. All-wheel drive and extraelectric power are always available regardlessof the battery's charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will be displayed in the instrument panel. Thegauge will indicate the amount of electricalcurrent required when the driver depressesthe accelerator pedal. The marker between thelightning and the drop shows how much cur-rent 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 restoredto the battery (regenerated) duringlight braking.

Pure
Uses the electric motor only, with the low- est possible energy consumption and car-bon dioxide emissions.
This drive mode prioritizes the use of thehybrid battery. Certain climate system func-tions are reduced to provide the longest dis-tance using only electricity.
Pure mode is available when the hybrid bat-
tery is sufficiently charged. Even in Puremode, the combustion engine will start if the charge level in the battery gets too low. Thecombustion engine will also start
if the vehicle's speed goes above125 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 adapted for the longestpossible driving distance with electric propul-sion and is primarily intended for use in city driving.
Pure helps provide the lowest possi-
ble consumption even when the hybrid battery is fully discharged. ECO climate is activated tocontrol the climate in the passenger compart-ment, and in slippery road conditions slightlymore wheel spin may be permitted before all-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically
activated in the passenger compartment to help reduce energy consumption.
NOTE
When the Pure drive mode is activated,
settings for certain climate system and electricity consuming functions arereduced. Some of these settings can bereset manually, but full functionality 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 nor-mally.
Constant AWD
Improves the vehicle's traction and han- dling by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An adapted distribution between frontand rear axle torque provides effective control,stability and traction, e.g. on slippery roads orwhen towing a heavy trailer or another vehicle. The
Constant AWD drive mode is always
available regardless 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 driveaccording to the road surface, and can acti-vate the electric motor or start the combustionengine as needed.
Power

The vehicle gets sportier driving characte- ristics and a faster acceleration response.
This drive mode adapts the combined powerfrom the combustion engine and the electricmotor by providing power to both the frontand rear wheels. Gear shifting will be fasterand more distinct and the transmission willprioritize gears with a higher traction force.Steering response is faster and suspension isstiffer. Both the combustion engine and the electric motor are engaged to enable all-wheel drive,which results in higher fuel consumption.
