Important safety notes

G
WARNING
Operating the integrated information systems
and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There
is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
You should therefore make sure your vehicle
is operating safely at all times. Otherwise, a
vehicle that is not operating safely may cause
an accident. If your vehicle is not operating
safely, stop and park safely as soon as pos-
sible.
