Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
Th e speed warning system warns the driver if he exceeds a previously
stored maximum speed. A warning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
same time, a warning symbol appears in the display.
The speed warning system has
two warning thresholds that function
independently of each other and that have somewhat different
purposes :
Speed warning 1
You can use speed warning 1 to set the maximum speed while you are
driving. This setting w ill remain in effect until you turn off the igni­
tion, assum ing that you have not changed or reset the setting .
Th e speed warning symbo l
'8 (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed.
It goes out when the speed falls be low the stored maximum speed.
Th e speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted.
