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.
Setting spee d warning 1
=> page 35.
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.

The estimated cruising range in miles (km) appears in the display .
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

your dr iv ing techn ique to achieve a desired mileage. ..,

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.
Average speed
Th e average speed in mph (km/h) since the last time the display w as

Electronic immobilizer
The immobilizer helps to prevent unauthorized use of
your vehicle.
A computer chip inside your key automatically deactivates the elec ­
tronic immobilizer when you insert the key in the ignition lock, or on
vehicles with Convenience key*, when the key is inside the vehicle.
When you remove the key from the ign it ion lock , or on veh icles with
Convenience key, when you remove the key from the vehicle, the elec­
tronic immobilizer is automatically activated once again.
& WARNING
Always take the key with you when you leave the vehicle. The key
can disarm the electronic engine immobilizer and permit an unau­
thorized person to start the engine and enable operation of the
vehicle systems such as power window or power sunroof leading
to serious personal injury .
(I) Tips
• The immobilizer prevents unauthorized use of the vehicle. The
vehicle cannot be sta rted if an unauthorized key is used. The vehicle
may not start if another radio device such as a key for another vehicle
or a transponder is located on the key ring.
