Important safety notes
G
WARNING
If you do not have the prescribed service/
maintenance work or any required repairs carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb or a hole in the road
R a heavy object strikes the undercarriage
or parts of the chassis Introduction

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.
PLUG-IN HYBRID vehicles: charging the high-
voltage battery (Y page 209).

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 (Y page 276).48
