Introduction
LaFerrari is a hybrid vehicle: traction is provided by an internal
combustion engine and an electric motor powered by a high
voltage battery located under the passenger compartment.
More specifically, LaFerrari has a parallel hybrid system called
Hy-Kers: the internal combustion engine (1) and the electric
traction motor (2) are both connected directly to the transmission.
The system combines use of the internal combustion engine
with the electric traction motor resulting in an improvement in
performance and a reduction in fuel consumption and emissions.
In certain driving conditions, the electric motor also acts as a
generator by capturing the kinetic energy that would normally be
lost as heat energy and transforming it into electricity to recharge
the high voltage battery.

Some components which are normally driven by a combustion
engine in a conventional vehicle (for example, the power steering
pump) are powered by electricity supplied by the 12V electrical
system. The high voltage battery, on the other hand, powers the air
conditioning and heating system compressor. There is also a second
electric motor that serves as an alternator, a component that is not
therefore needed on this vehicle.
This guide provides the information necessary to work as safely as
possible in the event of an emergency involving this vehicle.
The emergency procedures for the LaFerrari are similar to
those for conventional vehicles, with the addition of a number of
specific provisions regarding components powered by high voltage
electricity.
This guide also describes the procedure to deactivate the high
voltage system in the event of an emergency.

Warning
Failure to observe the procedures indicated herein during
emergency rescue procedures may result in severe or fatal burns
or electric shock. Please read this manual thoroughly in order to
fully understand the characteristics of this vehicle and be able
to act correctly in the event of this vehicle being involved in an
accident.
Carefully observing the procedures indicated in this manual will
contribute to the success of a rescue operation.
Warning
The LaFerrari is equipped with numerous safety systems
designed to protect you from injury. These systems and features
make it possible to access the vehicle safely in special conditions.
However, when approaching a hybrid vehicle that is damaged
or has been involved in an accident or fire, or in the event or
rescue or recovery involving a hybrid vehicle, always assume
that the high voltage system of the vehicle is live.
How to identify the “LaFerrari”
The distinctive aerodynamic forms of the LaFerrari make it easily
identifiable. However, in certain cases, collision damage may make
the vehicle difficult to identify. In these situations, emergency
response personnel must visually inspect the vehicle to ascertain
whether it is equipped with high voltage components.
The wording “HYBRID VEHICLE” under the chassis number on
the left hand side of the windscreen indicates that the vehicle is
equipped with a high voltage hybrid system.

Hybrid system precautions
Warning
In addition to a conventional 12V electrical system, the vehicle
also has a 480 volt high voltage system.
High voltage is extremely dangerous and may cause serious
burns and electric shocks which can result in serious or fatal
injury.
Warning
Each component in the high voltage system is identified by a
special label indicating a potential risk of electric shock whereas
the cables in the high voltage system have an orange covering.
The symbol shown above identifies the vehicle high voltage
electrical parts that may put your safety at risk.
Important note
The high voltage system is energised when the ignition key is in
position II (key-on).
Important note
The high voltage electrical system is not energised when:
- the ignition key is in position 0 (key-off)
- the inertia switch has been activated

Warning
Risk of serious burns or electric shock resulting in injuries
that can be fatal.
The high voltage electrical system and high voltage battery are
dangerous and may cause burns, other serious injuries or death.
Never attempt to remove or tamper with the high voltage cables
(with orange covering), the high voltage battery, connectors
or any other component in the high voltage electrical system,
especially if it appears to be damaged.
