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.

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.

Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that:
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Monthly:
Check cold tire pressure in all tires. Inspectthe tires for wear.
Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
Clean interior glass surfaces with a glasscleaner and soft paper towels.
Wipe driver information displays with a softcloth.
Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.

As needed:
Wash the car, including the undercarriage, toreduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues.
Clean leaves and twigs from air intake vents atthe base of the windshield, and from other placeswhere they may collect.

Data transfer between vehicle andworkshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-work for secure data transfer between your vehi-cle and the workshop. Your visit to the workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your servicetechnician can connect your vehicle to the work-shop's Wi-Fi network to perform troubleshootingand download software. For this type of commu-nication, the vehicle only connects to a work-shop's network. It is not possible to connect thevehicle to another Wi-Fi network (e.g. your homenetwork) in the same way as to a workshop's net-work.

Connecting with remote key
Connection is usually managed by the servicetechnician, who will use the remote key buttons. Itis therefore important to bring a key with buttonswith you when you visit the workshop. Pressingthe lock button on the remote key three times willconnect the vehicle to the workshop's Wi-Fi net-work.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.
