Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver 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 symbol 's
appearance might be different in some models .
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, assuming that you have not changed or reset the setting .
The speed warning symbo l
0 (USA models)/0 (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.
The 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.
Setting speed warning 1
=> page 25.
Speed warning 2
Storing warning 2 is recommended if you always want to be reminded
of a certain speed, for example when you are travel ing in a country
that has a general maximum speed limit, or if you do not want to
exceed a specified speed for winter tires.
The speed warning 2 symbol,
8, (USA models)/ 8, (Canada models)
appears in the display when you exceed the stored speed limit. Unlike

(I) Tips
Even though your veh icle is equipped with a speed warn ing system,
you should still watch the speedometer to make sure you are not
dr iv ing faster than the speed limit.•
