HYBRID INFORMATION

General information about Twin Engine Twin Engine vehicles are driven just like any other vehicle, but certain functions differ froma vehicle powered exclusively by gasoline.The electric motor powers the vehicle primar-ily at low speeds; the gasoline engine is usedat higher speeds or during more active driv-ing.
The instrument panel displays Twin Engine- specific information - charging information,selected drive mode, distance to dischargedbattery and hybrid battery charge level. Different drive modes can be selected while driving, e.g. electric power only or, if morepower is needed, a combination of electric andgasoline power. The vehicle calculates a com-bination of driveability, driving experience,environmental impact and fuel economy forthe selected drive mode. In order to function optimally, the hybrid bat- tery (and its electrical drive systems) and thegasoline engine (and its drive systems) mustbe at the correct operating temperature. Bat-tery capacity can be considerably reduced ifthe battery is too cold or too hot. Precondi-tioning prepares the vehicle's drive systemsand passenger compartment before driving tohelp reduce both wear and energy consump-tion. It also helps increase the hybrid battery'srange.The hybrid battery which powers the electricmotor is recharged using the charging cable. Itcan also be recharged during light braking andthrough engine braking in gear position
B. The
combustion engine can also help recharge thehybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical cur- rent to the vehicle, i.e. the ignition is switchedoff or the start battery is discharged, certainfunctions such as brakes, power steering, etc.will not work.
WARNING
If the vehicle does not have electrical cur- rent and both the electric motor and thegasoline engine are switched off, thebrakes cannot be used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another vehicle, as this could damage theelectric motor.
Exterior engine noise
Because there is no sound from the engine when only the electric motor is running, thevehicle is equipped with artificial exteriorbackground noise. This sound is intended tohelp warn children, pedestrians, cyclists, ani- mals, etc. outside the vehicle of the vehicle'sapproach.
High-voltage electrical current
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly. These com-ponents and any orange wiring in the vehi-cle may only be handled by trained andqualified Volvo service technicians.
Do not touch anything that is not clearly described in this Owner's Manual.

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.

Charge cable
The charging cable is used to recharge your vehicle's hybrid battery.
The charging cable is stored in a storage compart- ment under the cargo compartment floor.
WARNING
Only use the charging cable provided with your vehicle or a replacement cable pur-chased from a Volvo retailer.

Open the charger door and remove the charging socket's protective cover. Pushthe charging handle all the way into thevehicle's socket.2. The charging cable handle will lock into
place and charging will begin within5 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.

Graphic Message
Meaning
Fully charged at: [Time] displayed along with an animated blue
pulsing light through the charging cable. Charging is in progress and the approximate time at which the battery will be fully charged is displayed.
Charging complete is displayed. An image will be superimposed
over the graphic of the vehicle with a green LED indicator light in the socket. The battery is fully charged.
Charging error will be displayed. The LED indicator light in the
charging socket will be red. Malfunction. Make sure the charging cable is correctly con- nected to the vehicle's charging socket and to the120/240 V outlet (alternating current).

Long-term storage of vehicles with hybrid batteries To help minimize degradation of the hybrid battery if the vehicle is not driven for a pro-longed period (longer than 1 month) thehybrid battery charge level should be kept atapprox. 25% according to the gauge in theinstrument panel.
Do as follows:
1. If the hybrid battery charge level is high,drive the vehicle until the charge level is approximately 25%. If the charge level islow, charge the battery until the level rea-ches approximately 25%. 2. If the vehicle is not driven for more than 6
months or the hybrid battery's chargelevel is noticeably below the 25% mark,charge the battery to about 25% to helpcompensate for the natural battery dis-charge that occurs in long-term storage.Regularly check the charge level using thegauge in the instrument display.
NOTE
Store the vehicle in as cool a location as possible to minimize battery aging duringlong-term storage. In the summer, park thevehicle indoors or in a shady location,whichever is cooler.

Ignition modes The vehicle's ignition can be put in various modes (levels) to make different functionsavailable.
To enable the use of a limited number of func- tions when the engine is not running, the igni-tion can be put in one of three different levels:0
, I and II. These levels are referred to as "igni-
tion modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:

BSteady glow for 2 seconds after the engine is started: Automaticfunction check. Steady glow for more than 2 seconds: Fault in the ABS sys-tem. The vehicle's regular brakesystem is still working, but with-out the ABS function.
If the message Brake pedal

is displayed, the
"Brake-by-wire" system is not functioning properly. Greaterpressure will be required to brakethe vehicle.
A In Canada.
B In the US.
WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.
