Operating safety
Important safety notes
GWARNING
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/
maintenance work as well as any required
repairs carried out at a qualified specialist
workshop.
GWARNING
If you switch off the ignition while driving,
safety-relevant functionsare only available
with limitations, or not at all.This could affect,
for example, the power steering and the brake
boosting effect.You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other
networked components. In particular,
systems relevant to safety could also be
affected. As a result, these may no longer
function as intended 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
electronic components or their software. You
should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck,e.g. on a high
curb or an unpaved road
Ryou drive too fastover an obstacle, e.g.
a curb or a hole in the road
Ra heavy object strikes the undercarriage
or parts of the chassis.
In situations like this, the body, the
undercarriage, chassis parts, wheels or
tires could be damaged without the
damage being visible.Components
damaged in this way can unexpectedly fail
or, in the case of an accident, no longer
withstand the strain they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system for an
extended period, they can catch fire.
Have the vehicle checked and repaired
immediately at a qualified specialist
workshop. If on continuing your journey
you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic
conditions. In such cases, visit a qualified
specialist workshop.
