High-voltage battery
G WARNING
In the event of a vehicle fire, the internal pres-
sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
G WARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery.
Hybrid vehicles: if the vehicle is idle for
lengthy periods, run it for a few minutes
once every six weeks to charge up the high-
voltage battery. During the charging proc-
ess, switch off all electrical consumers, e.g.
the automatic climate control or the seat
heating.
Plug-in hybrid vehicles: if the vehicle is
idle for lengthy periods leave the high-volt-
age battery connected to a charging sta-
tion.

RBS driving safety system (Recupera-
tive Brake System)
The Recuperative Braking System supports
you when braking with an electronically-con-
trolled brake boost mode and enables the
recovery of kinetic energy (recuperation).
G WARNING
If the Recuperative Braking System malfunc-
tions, braking resistance may be reduced and
brake pedal travel may be longer than usual. If
you subsequently depress the brake pedal as
usual, the braking effect may not be sufficient.
There is a risk of an accident.
In the event of this malfunction, continue to
depress the brake pedal. Stop the vehicle in
accordance with the traffic conditions. If nec-
essary, contact a qualified specialist work-
shop.

Braking System ( page 276).
