Engine oil pressure malfunction 9=7-
The red engine oil pressure warning symbol requires

engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip .
• The yellow oil level warning indication -requires oil refill or
workshop service without delay. Do not wait until the red oil pres
sure warning

level warning . By then, your engine may already have suffered
serious damage. •

Speed warning system
Overview
The spee d warning system helps you to keep your driving
speed below a set speed limit.
Fig. 19 D ispl ay : s pee d
wa rning sy st em
The speed warning system warns the driver if he exceeds a previ
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 3 miles per hour (3 km/hl. At the same time, a warning symbo l appears in the display
~fig.19.
The speed warning system has
two warning thre sh old s that func
tion 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 will remain in effect un til you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
C-~ (USA models)/ (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. .,
~ehicle care Technical data
Page 38 of 340
Driver inf orma tion d ispl ay
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 de leted .
Setting speed warning 1
~ page 36 .
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.
The speed warning 2 symbol,
~ (USA models)/ :, (Canada models)
appears in the disp lay 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.

[ i ) Tip s
Even though your vehicle is equipped with a speed warning system,
you should still watch the speedometer to make sure you are not
driving faster than the speed limit .•
