can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting
system, ABS (anti-lock braking system) or
ESP ®
(Electronic Stability Program). The
operating safety of your vehicle may be
restricted. You could lose control of the
vehicle, for example:
R braking
R in the event of abrupt steering maneuver
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar
incident, contact a qualified specialist
workshop immediately. Do not drive any
further. You should have all work involving the
battery carried out at a qualified specialist
workshop.
For further information about ABS and ESP ®
,
see (Y page 67) and ( Ypage 69). G

of sparks, which could ignite the highly
explosive gases of a battery. There is a risk of
an explosion.
Before handling 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. 316
