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.•

Auto Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the veh icle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone. The displays are color
coded in e ither red or yellow depend ing on their level of priority . A
red symbol means
Danger, a yellow symbol indicates Warning . In
certain situations, information message for the driver appear in addi­

Th e Auto-Check Contro l will automatically perform a test each time
you switch on the ignition. With the selector lever in
P or N, the
following message appears in the display:
When stationary apply footbrake while selecting gear.
When you a select a different gear (for example: R, D, etc.), the
message will disappear and the Auto-Check function is displayed.
If there is a malf unction, then the malfunction message will appear
about 15 seconds after you start the vehicle. At the same time you
w ill hear a wa rning tone. •

engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.

level warning ~ . By then, your engine may already h ave suffered
serious damage. •
