For safety reasons, you should only enter a 
destination when the vehicle is stationary. 
When the vehicle is in motion, a passenger 
should enter the destination. Study manual 
and select route before driving. 
Do not watch display screen or operate but-
tons while the vehicle is in motion - let voice 
instructions guide you. Stop at a safe locati-
on before using buttons or making correc-
tions.
Traffic regulations always have priority over 
any route recommendations given.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your car is co-
vering a distance of 44 feet (approximately 
14 m) every second. 
The route calculated by COMAND is a re-
commendation on how to best reach your 
selected destination.
During route guidance, you will not receive 
any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges
Similar traffic regulation data
You should therefore always strictly observe 
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road 
signs even if they contradict COMAND in-
structions.
