Charging the hybrid battery In addition to the conventional fuel tank, your vehicle is also equipped with a rechargeablelithium-ion hybrid battery.
The hybrid battery can be recharged using the charging cable stored in a storage space in thecargo compartment.
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or subjected to flooding, fire, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
WARNING
If the hybrid battery needs to be replaced, this may only be done by Volvo retailer or author-ized Volvo workshop.
Charging cable handle and charging socket.
Charging status is indicated in three ways: • The indicator lights in the charging module (the unit connected to the wall outlet).
• Indicator light in the vehicle's chargingsocket.
• Images and text in the instrument panel.
The hybrid battery's charging process alsocharges the vehicle's start battery. If the hybrid battery's temperature is below -10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not available at all. The electric motor cannot be used if the battery'stemperature is too low or too high. If the PUREdrive mode is selected, the gasoline engine willstart.
Charging using the gasoline engine
The vehicle generates electrical current to charge the battery, e.g. when the driver lightly presses the brakepedal or when engine braking is used on downgrades.
The vehicle can also generate current to the hybrid battery to charge it.
• The hybrid battery can also be recharged bylightly depressing the brake pedal, i.e. duringlight braking. This converts the vehicle'skinetic energy to electrical energy, which isused to charge the hybrid battery.

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 a num-ber of automatic brake assist functions. Thesesystems help the driver by e.g. keeping the vehi-cle stationary when the brake pedal is notdepressed (e.g. at a traffic light or intersection),when starting up a hill or when driving down a hill. Depending on how the vehicle is equipped, the following brake assist functions may be included:
• Auto-hold brakes (Auto Hold)
• Hill Start Assist (Hill Start Assist)
• Braking assist after a collision
• City Safety
• Hill Descent Control (Hill Descent Control)

Brakes The brake pedal is used to apply the vehicle's regular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. If one brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.
WARNING
If the vehicle does not have electrical current and both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop 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 BrakingSystem (ABS), which can help prevent thewheels from locking and help maintain steeringcontrol when braking. Vibrations may be felt fromthe brake pedal when ABS is operating, which isnormal. After the vehicle is started, a brief test of the ABS 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 batteryWhen 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 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 used to

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habits and 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.

• Brakes (p. 419)
Braking on wet roads
Prolonged driving in heavy rain without braking may cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

• Braking on salted roads (p. 421)
Braking on salted roads When driving on salted roads, a layer of salt may form on the brake discs and brake pads.
This could increase stopping distance. Maintain an extra large safety distance to the vehicleahead. Make sure to also:
• Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
• Gently apply the brakes when you have fin-ished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system components for wear.
To keep the vehicle as safe and reliable as possi- ble, follow the Volvo service schedule specified inthe Warranty and Maintenance Records Informa-tion booklet. New and replaced brake pads andbrake discs do not provide optimal braking effectuntil they are "broken in" by driving a few hun-dred kilometers (miles). Compensate for thereduced braking effect by applying greater pres-sure to the brake pedal. Volvo recommends onlyusing brake pads approved for your Volvo.
CAUTION
The brake system's components should be regularly checked for wear. Contact a workshop for advice on how to do this or let a workshop perform the inspection- an authorized Volvo workshop is recom-mended.

Parking brake The parking brake helps keep the vehicle sta- tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel console between the seats.
When the electric parking brake is being applied, a faint sound can be heard from the brake's elec-tric motor. This sound can also be heard duringthe automatic function check of the parkingbrake. If the vehicle is stationary when the parking brake is applied, it will only be applied to the rearwheels. If it is applied while the vehicle is moving,the normal brakes will be used on all four wheels.Braking will be transferred to only the rearwheels when the vehicle is almost stopped.

Auto-hold brakesWith the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle stops, the brakes are activated automatically. The function can use either thenormal brakes or the parking brakes to keep thevehicle stationary and works on flat surfaces orhills. When driving off, the brakes will be automat-ically released if the driver's seat belt is buckled.
NOTE
When braking to a stop on an uphill or down- hill gradient, depress the brake pedal withslightly more force than usual before releas-ing to ensure that the vehicle cannot move atall.
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)

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 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 driving. Hill Start Assist is available even if the Auto-hold brake function is switched off.

Braking assist after a collision In a collision in which the activation level is reached 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 are activated during braking. When the vehicle has stopped, 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 risk of being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal. This function assumes that the brake system is intact after a collision. Brake assist is part of the Rear Collision Warning and Blind Spot Information safety systems.

Drive modes
Drive modes affect the vehicle's driving charac- teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle's many functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode: • Steering
• Engine/transmission/all-wheel drive
• Brakes
• Pneumatic suspension
* and shock absorbers
• Instrument panel
• Climate control settings
Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
WARNING
Keep in mind that the vehicle does not emit any engine noise when using the electricmotor and may therefore be difficult to detectfor children, pedestrians, cyclists or animals.This is particularly true at low speeds, e.g. inparking lots.
WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and the com-bustion engine switched off. The engine willstart automatically if the charge level in thehybrid battery is low and the resulting exhaustgases can be very harmful to people and ani-mals.
HYBRID
• This is the default mode in which the electric motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control system uses both the electric motor and the gas-oline engine - separately or in tandem - and cal-culates optimal utilization with regard to perform-ance, fuel consumption and comfort. At highspeeds, ground clearance is automatically low- ered 4
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the need for heat/cooling in the passenger compart-ment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power. Whenthe accelerator pedal is pressed, only the electricmotor will be activated until the battery reaches acertain charge level. Above this level, the currentin the battery cannot supply the power requestedby the accelerator pedal and the combustionengine will start. When the hybrid battery's charge level is low, the combustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 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 con- sumption with an optimized mix between theelectric motor and gasoline engine, without com-promising on climate comfort or driving experi-ence. When faster acceleration is requested bythe driver, the electric driveline will be utilized tohelp provide maximum additional power. Thevehicle also monitors the driving conditions andautomatically engages all-wheel drive if neces-sary. All-wheel drive and extra electric power arealways available regardless of the battery'scharging status.

Hill Descent Control The function for assisting when driving downhill, Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes. The function is included in the Off Road drive mode.
HDC is designed for driving on rough roads at low speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.
WARNING
HDC is only intended to be a supplementary braking aid and it does not function in all sit-uations. The driver is always ultimately responsible for operating the vehicle in a safe manner.
FunctionHill Descent Control allows the vehicle to move forward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle willreturn to very low speed regardless of how steep
