Road sign information (RSI)* - operation
The road sign information function (RSI – Road Sign Information) helps the driver to remember which speed-related road signs the car has passed.
The function is operated as follows
When RSI has recorded a road sign with an imposed speed, the combined instrument panel displays the sign as a symbol.
Together with the symbol for the current speed limit, a sign showing that overtaking is prohibited may also be displayed where appropriate.
End of restriction or motorway
A corresponding road sign is shown in the combined instrument panel for approx. 10 seconds in situations where RSI detects a sign that involves the end of a speed limit - or other speed-related information, e.g. end of a motorway.
Examples of such signs are:
End of all restrictions.
End of motorway.
Following which, the sign information is hidden until the next speed-related sign is detected.
Sometimes different speed limits are signposted for the same road - an additional sign then indicates the circumstances under which the different speeds apply. The road section may be particularly susceptible to accidents in rain and/or fog, for example.
An additional sign relating to rain is displayed only if the windscreen wipers are in use.
The speed applicable on an exit is indicated in certain markets by means of an additional sign containing an arrow.
Speed signs linked to this type of additional sign are displayed only if the driver is using the direction indicator.
Some speeds are applicable only after e.g. a specific distance or at a certain time of day. The driver's attention is drawn to the situation by means of a symbol for an additional sign under the symbol showing speed.
Display of additional information
A symbol for additional sign in the form of an empty frame under the combined instrument panel's speed symbol means that the RSI has detected an additional sign with supplementary information for the current speed limit.
Setting in MY CAR
There are options for RSI in the MY CAR menu system; see MY CAR.
Road sign information On/Off
The combined instrument panel's speed symbol display can be disabled. The function can be activated/deactivated in the menu system MY CAR. For a description of the menu system, see MY CAR.
The driver can opt to receive a warning when the applicable speed limit is exceeded by 5 km/h or more. This warning is given by the symbol showing the applicable maximum speed temporarily flashing when this speed is exceeded. The function can be activated/deactivated in the menu system MY CAR. For a description of the menu system, see MY CAR.
