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 the driver if he exceeds a previ ­
ous ly stored maximum speed. A warning tone will sound as soon as
the vehicle speed exceeds th e set speed by about 3 mph (3 km/h). At
the same t ime, a warning symbol appears in the display .
The speed warning system has
t w o wa rnin g thr eshol ds that func­
tion independent ly of each other and that have somewhat different
purposes:
S peed warnin g 1
You can use speed warning 1 to set the maximum speed while you
are driving. This setting will remain in effect until you turn off the
ignition , assuming that you have not changed or reset the se tting .
The speed warning symbol
0 (USA models) /0 (Canada models) in
the warning 1 display appears when you exceed the maximum speed . It goes out when the speed falls below the stored maximum
speed .
The speed warning symbol wi ll also go out if the speed
e xce eds the
stored maximum speed by more than about 25 mph
(40 km/h) for at
leas t 1 O seconds. The stored maximum speed is deleted .
Setting speed warning 1 :::::,
page 37.

Speed warning 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
Th e speed warning 2 symbol,
8, (USA models)/ 8, (Canada models)
appears in the display when you exceed the stored speed limit.
Unlike warning 1, it will not go out until the vehicle speed drops
below the stored speed limit.

you should still watch the speedometer to make sure you are not
driving faster than the speed limit. •
