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.

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.

• Brakes (p. 429)
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.

Parking brake malfunctionIf you are unable to deactivate or activate the parking brake after several attempts, contact anauthorized Volvo workshop.
A audible warning signal will sound if the parking brake is applied while the vehicle is being driven. If the vehicle must be parked before the problem is rectified, turn the wheels as when parking on an incline and put the gear selector in P.
Low battery charge levelIf the battery charge level is too low, it will not be possible to apply or release the parking brake.Connect an auxiliary battery to the vehicle if thebattery is discharged.
Replacing brake padsDue to the design of the electric parking brake,the rear brake pads must be replaced by a work-shop. An authorized Volvo workshop is recom-mended.
