Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
T he speed warning system warns the driver if he exceeds a previously
s tored maximum spee d. A w arning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h) . A t the
same time, a warning symbol appears in t he disp lay .
Th e spee d wa rn ing system has
two warning threshold s that function
independently of each other and that have somewhat di fferent
purp oses:
Speed warning 1 8 (USA models) /8 (Canada
models)
You can use speed warn ing 1 to set the max imum speed w hile you are
driv ing. This setting will remain in effect until yo u turn off the igni­
tion, assum ing that yo u have not changed or reset the setting .
Th e spee d warn ing symbo l
B (USA models)/ 0 (C anad a mode ls) in
t he warning 1 display appears when you exceed the maxim um speed .
It goes out when the speed falls be low the stored maximum speed .
Th e spee d warn ing sy mbo l w ill also go o ut if t he speed
exceeds the
sto red maxim um speed by more than about 25 mph
(40 km/ h) for at
least
10 sec onds . H oweve r, th is doe s not rese t the stored maxim um
speed.

Speed warning 2 0 (USA models) /0 , (Canada

Storing warn ing 2 is recommended if you always want to be reminded
o f a ce rtain speed, fo r example when yo u are traveling in a co untr y
that has a genera l maximum speed lim it, or if you do not want to
exceed a specified speed for winter tires.

T his tells you how far your vehicle w ill be ab le to travel on t he cu rre nt
tank of fuel and w ith the same driv ing style. The display changes in
increments of 6 miles
(10 km) .
The cru is ing range is ca lculated based on the fuel consumpt ion for
the last 18 miles
(30 km). If you drive conservatively, the cruising
range will increase .
Average fuel mileage
The average fuel economy in MPG (l/100 km) s ince you last clea red

Current fuel mileage
T he instantaneous fuel consumption in miles per ga llon (l/100 km) is
show n in this disp lay. You can use this d isp lay to adjust you r driv ing
technique to achieve a desired m ileage .
Fuel consumption is recalculated at inte rvals of 33 ya rds (30 metres).
When the vehicle is stat ionary, the most recent fuel consumption is
displ ayed.
