HYBRID INFORMATION

General information about TwinEngine
Twin Engine vehicles are driven just like any other vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe- cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level. Different drive modes can be selected while driv- ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode. In order to function optimally, the hybrid battery (and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range. The hybrid battery, which powers the electric motor, is recharged using the charging cable. Itcan also be recharged during light braking and through 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 current to the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.
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.
Towing not permitted
Never tow a Twin Engine vehicle behind another vehicle, as this could damage the electric motor.
Exterior engine noise
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 especially true at low speeds, e.g. inparking lots.
High-voltage electrical current
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure. These componentsand any orange wiring in the vehicle may onlybe handled by trained and qualified Volvoservice technicians.
Do not touch anything that is not clearly descri- bed in this Owner's Manual.

Engine compartment overview
This overview shows some service-related com- ponents.
Some of the components included in the vehi- cle's electric drive system are located in theengine compartment. Exercise caution whenaccessing the engine compartment and onlytouch what is required for normal maintenance.
WARNING
Orange wiring may only be handled by quali- fied personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure.
• Do not touch anything that is not clearly described in this Owner's Manual.
• Be careful when checking/filling fluids inthe engine compartment.
The layout of the engine compartment may vary depend- ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver's side)
Washer fluid filler pipe 11
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off. Always entrust engine washing to a workshop – an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicle electrical system should always be in ignition mode
0
when work in being performed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system is in igni- tion mode II or when the engine is warm.

Fuses and fuseboxes
All electrical functions and components are pro- tected by a number of fuses in order to protectthe vehicle's electrical system from damage byshort circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possiblylead to a fire.
WARNING
Orange wiring may only be handled by quali- fied personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure. Do not touch anything that is not clearly described in this Owner's Manual.
If any electrical component or function is not responding, the component may have blown afuse due to temporary overload. If the same fuse blows repeatedly, there may be a problem with the component. Volvo recommends contacting anauthorized Volvo workshop to have the compo-nent checked.
