Ignition modes
The vehicle's ignition can be put in variousmodes (levels) to make different functions availa-ble.
To enable the use of a limited number of func-tions when the engine is not running, the ignitioncan be put in one of three different levels: 0, Iand II. These levels are referred to as "ignitionmodes" in the Owner's Manual.
The following table shows which functions areavailable in each ignition mode:
Mode Functions
0The odometer, clock and tem-
perature gauge are illuminatedA.
The power* seats can beadjusted.
The power windows can be used.
The center display is activated
and can be usedA.
The infotainment system can be
usedA.
In this mode, the functions are availa-ble for a limited time and then switchoff automatically.
IThe panoramic roof, power win-dows, 12-volt electrical socket inthe passenger compartment,Bluetooth, navigation, phone,blower and windshield wipers canbe used.
The power seats can be adjusted.
The 12-volt electrical socket* inthe trunk can be used.
Electrical current will be takenfrom the battery in this ignitionmode.
Mode Functions
IIThe headlights illuminate.
Warning/indicator lights illumi-nate for 5 seconds.
A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!

Brakes
The brake pedal is used to apply the vehicle'sregular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. Ifone brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.
WARNING
The power brakes only work when the electricmotor or combustion engine is running.
If the brake pedal is used when the engine isswitched off, greater pressure must be applied tobrake the vehicle.
In very hilly areas or when driving with a heavyload, gear position B can be used to augment thebrakes with engine braking.
Anti-lock brakes
The vehicle is equipped with an Anti-lock BrakingSystem (ABS), which helps prevent the wheelsfrom locking and helps maintain steering controlwhen braking. Vibrations may be felt from thebrake pedal when ABS is operating, which is nor-mal.
After the vehicle is started, a brief test of theABS system is automatically performed when the
driver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.
Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor braking function is used. This converts thevehicle's kinetic energy into electrical energy,which is used to charge the hybrid battery. Whenthe battery is being charged with the electricmotor braking function, this will be indicated inthe instrument panel.
When the battery is being charged with the electricmotor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is used to
augment braking. This is indicated in the instru-ment panel with the pointer down in the red area.

AIn Canada.BIn the US.
WARNING
If the warning symbols for both brake faultand ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is normalwhen this occurs, drive carefully to thenearest workshop to have the brake sys-tem checked - an authorized Volvo work-shop is recommended.
If the brake fluid has fallen below the MINlevel in the brake fluid reservoir, the vehi-cle should not be driven until the brakefluid has been filled. The reason for thebrake fluid loss must be checked.

Brake Assist System
The brake enhancing system, Brake AssistSystem (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habitsand increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.

Hill Start Assist
The function for assisting when starting the vehi-cle on inclines, Hill Start Assist (HSA), helpsprevent the vehicle from rolling backward whenstarting on an uphill gradient. When backing upa hill, HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-holdbrake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.
