Important safety notes
Work on the battery, e.g. removin gorinstal-
ling ,requires specialist knowledge and the
use of special tools. Therefore, always have
work on the batter ycarried out at aqualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to ashort circui tand
damage your vehicle's electronic system. This
can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP
®
(Elec-
tronic Stability Program).
R If ABS malfunctions ,the wheels can lock
during braking. This limits the steerability
of the vehicle when brakin gand the braking
distance may increase. There is arisk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it start stoskid or awheel star ts
to spin. There is arisk of accident.
You should therefore have all work involving
the batter ycarried out at aqualified specialist
workshop. G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of abattery. There is arisk of an
explosion.
Befor ehandling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting.
Always make sure that neither you nor the
batter yiselectrostatically charged. There is
ab uild-up of electrostatic charge, e.g.:
R by wearing clothing made from synthetic
fibres
R due to friction betwee nclothin gand seats
R if you pus horpull the batter yacross the
carpe torother synthe ticm aterials
R if you wipe the batter ywithacloth. G
WARNING
Durin gthe charging process, abatter yprodu-
ces hydroge ngas. If ashort circui toccurs or
sparks are created, the hydroge ngas can
ignite. There is arisk of an explosion. 382
