WARNING
Only use the on-board computer when road
and traffic conditions permit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such as
speed, outside temperature, warning and indi-
cator lamps, display messages or system fail-
ures. Driving characteristics may be impaired.
Adjust your driving style and vehicle speed
accordingly.
Contact a qualified specialist workshop
immediately. G
WARNING
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always
make sure that your vehicle is safe to use. You
could otherwise cause an accident by driving
an unsafe vehicle. G
WARNING
The operating safety of your vehicle could be
impaired if maintenance work is carried out
incorrectly. This could cause you to lose con-
trol of your vehicle and cause an accident.
Moreover, the safety systems may no longer
be able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop.
