Charging current Charging current is used to charge the hybrid battery and precondition the vehicle. Charg-ing is performed by connecting a chargingcable between the vehicle's charging socketand a 120/240 V electrical socket (alternat-ing current).
When the charging cable is activated, a mes- sage will be displayed in the instrument paneland an indicator light in the vehicle's chargingsocket will illuminate. Charging current is pri-marily used for battery charging, but is alsoused for preconditioning. The vehicle's startbattery is charged along with the hybrid bat-tery.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
NOTE
In extremely cold or hot weather, part of the charging current is used to heat/cool the hybrid battery and the passen-ger compartment, resulting in a longercharging time.
The charging time is longer if precondi-tioning has been selected. The timerequired depends primarily on theambient temperature.
FuseThere are normally several 120/240 V power consumers in one fuse circuit, which meansthat more than one power consumer (e.g.lighting, vacuum cleaner, electric drill, etc.)may use the same fuse.

HYBRID INFORMATION
3882. The charging cable handle will lock into
place and charging will begin within 5 seconds. When charging starts, thegreen LED light in the charging socket willbegin to flash. The approximate remainingcharging time or the charging status willbe displayed in the instrument panel. Charging may be temporarily interrupted if the vehicle is unlocked:
and a door is open
‒ charging will
restart within a few minutes.
if no door is opened
‒ the vehicle will
automatically relock. Charging willresume after 1 minute.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
During charging, condensation from the air conditioning may form under the vehicle. Thisis normal and is caused by the hybrid batterycooling.

When the charge module is initially plugged into a wall outlet, the red warning light willflash once to indicate that a startup safetycheck has been performed. When the safetycheck has been completed, the blue statusindicator will glow steadily and the red warn-ing light will be off. The charger is now readyto be used. If the red warning light continuesto flash or glows steadily, a fault has beendetected and the charger will not deliverpower to the vehicle. Contact a Volvo retaileror a certified Volvo service technician. When the charging cable is connected to thevehicle's charging socket, the blue light willflash once.

STARTING AND DRIVING

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. Main- tain an extra large safety distance to the vehi-cle ahead. 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 havefinished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system compo- nents for wear.
To keep the vehicle as safe and reliable as possible, follow the Volvo service schedulespecified in the Warranty and MaintenanceRecords Information booklet. After replacingbrake pads and brake discs, braking effect isnot adapted until they are "broken in" by driv-ing a few hundred kilometers (miles). Com-pensate for the reduced braking effect byapplying greater pressure to the brake pedal.Volvo recommends only using brake padsapproved 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 theinspection - an authorized Volvo workshopis recommended.

Brakes (p. 403)
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 thebrake's electric motor. This sound can also beheard during the automatic function check ofthe parking brake. If the vehicle is stationary when the parking brake is activated, it will only be applied to therear wheels. If it is activated while the vehicleis moving, the normal brakes will be used onall four wheels. Braking will be transferred toonly the rear wheels when the vehicle isalmost stopped.

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)

Braking assist after a collision
In a collision in which the activation level is reached for the pyrotechnic seat belt tension-ers or airbags, or if a collision with a large ani-mal is detected, the vehicle's brakes will beautomatically activated. This function isintended to help prevent or reduce the effectsof any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. Inorder to avoid or mitigate a possible furthercollision with a vehicle or an object in the vehi-cle's path, the brake assist system is activatedautomatically to help stop the vehicle safely. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the drivercan override the system by depressing theaccelerator pedal. This function assumes that the brake system is intact after a collision.

Transmission
The transmission is part of the vehicle's drive- line (power transmission) between the engineand the drive wheels. The function of thetransmission is to change gears dependingon speed and power needs.
The vehicle has an 8-speed automatic trans- mission and an electric motor for rear-wheeldrive. The number of gears allows the engine'storque and power band to be effectively uti-lized. Two of the gears are overdrive gears thatsave fuel when driving at a constant enginespeed. Manual shifting is also possible. Theinstrument panel shows the gear currently inuse.

Automatic transmission
In vehicles with an automatic transmission, the system selects the gear so that drivingwill be as energy-efficient as possible. Thetransmission also has a manual mode.
Overview of gear selector and gear shift pattern in the instrument panel
The instrument panel shows which gear is cur- rently in use: R , N , D or B. P position is electric.
For manual shifting, the gear indicator in the instrument panel displays the gear currentlybeing used.
