Hot exhaust system
Warning
High temperatures can occur underneath the
body, for instance caused by the exhaust
system, while driving. Contact with the ex-
haust system can cause burns. There is a risk
of injury. Do not touch the exhaust system,
including the exhaust pipe, when hot.
Warning
If combustible materials such as leaves or
grass come in contact with hot parts of the
exhaust system, these materials can ignite.
There is a risk of fire and an injury hazard.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts while driving, in
Neutral or during parking.
Mobile radio in the vehicle
Warning
Vehicle electronics and mobile communica-
tion devices can influence one another. There
is radiation due to the transmission oper-
ations of mobile communication devices.
There is a risk of injury or risk of damage
to property. If possible, in the car's interior
only use mobile communication devices such
as mobile phones with a direct connection to
an external antenna or the Personal eSIM in
order to prevent mutual interference and to
deflect radiation from the vehicle interior.
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
