2022 XC90 Volvo Road Sign Information
Road Sign Information
(Option/accessory)
The Road Sign Information function can help the driver to observe speed-related road signs and certain prohibition signs.
Examples of readable signs.
(Road signs are market-dependent – illustrations in these instructions only show a few examples)
RSI can provide information about such things as current speed, when a motorway or road is starting/ending, when overtaking is prohibited or when the direction of travel is one-way.
If the car passes a speed limit sign, it will be shown in the driver’s display and the Head-up display.
(Road signs are market-dependent – illustrations in these instructions only show a few examples)
Road Sign Information also includes subfunctions that can warn the driver if a speed limit has been exceeded or in connection with speed cameras.
Note
In certain markets, the road sign information function is only available in combination with map data.
Warning
- The function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
- The driver is advised to read all sections in the Owner’s Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
- Driver support functions are not a substitute for the driver’s attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
(Road signs are market-dependent – illustrations in these instructions only show a few examples)
The Road Sign Information function can receive speed-related information from Sensus Navigation.
If the car is equipped with Sensus Navigation(Road signs are market-dependent – illustrations in these instructions only show a few examples), speed information is read from the navigation unit in the following cases:
- On detection of signs that indirectly indicate a speed limit, such as motorway, dual carriageway and city limit signs.
- If a previously detected speed sign is assumed not to apply any longer, but no new sign has been detected.
Note
In certain markets, the Road Sign Information function is only available in combination with Sensus Navigation(Road signs are market-dependent – illustrations in these instructions only show a few examples).
Note
If a downloaded third-party app is used for navigation then there is no support for speed-related information.
Activating and deactivating Road Sign Information
(Road signs are market-dependent – illustrations in these instructions only show a few examples)
The Road Sign Information function (RSI(Road Sign Information)) is optional – the driver can choose to activate or deactivate this function.
Activate or deactivate the function using this button in the centre display’s function view.
- Illuminated button – the function is activated.
- Extinguished button – the function is deactivated.
Note
- If the automatic speed limiter function is activated, road sign information is shown in the driver display even if the Road Sign Information function is not activated.
- To remove road sign information from the driver display, you must deactivate both the automatic speed limiter and Road Sign Information.
- When the automatic speed limiter function is activated but Road Sign Information is deactivated, no warnings are given from Road Sign Information. Road Sign Information must also be activated in order to receive warnings.
Limitations of Road Sign Information
(Option/accessory)
The Road Sign Information function may have limitations in certain situations.
Examples of what can reduce the function are as follows:
- Faded signs
- Signs positioned on bends
- Rotated or damaged signs
- Signs positioned high above the roadway
- Fully/partially obscured or poorly positioned signs
- Signs completely or partly covered with frost, snow and/or dirt
- Digital road maps(Option/accessory) with outdated, incorrect or missing speed information(Option/accessory)
Note
In certain markets, the road sign information function is only available in combination with map data.
Note
The function for Road Sign Information may interpret some types of the bicycle rack, connected to the electrical socket for trailers, as a connected trailer. In such cases, the driver display may show incorrect speed information.
Note
This function uses the car’s camera and radar units, which have certain general limitations.
Warning for speed limitation and speed camera from road sign information
(Option/accessory)
Road Sign Information includes subfunctions that can warn the driver if a speed limit has been exceeded or in connection with speed cameras.
Warning for speed limit
The speed warning is given by the driver display symbol(Option/accessory) flashing when the maximum permissible speed is exceeded. The maximum permissible speed is determined by the speed limit in force, plus an optional margin that can be selected in the centre display under settings.
The speed warning alerts the driver when the applicable speed limit or stored maximum speed is exceeded. This warning is repeated once after approx. 30 seconds within one and the same speed limit zone unless the driver reduces the speed. Another warning is available only when the driver has reduced the speed by at least 5 km/h (3 mph) below the speed limit, and then exceeds it again, or when the car reaches a new area with a speed limit.
Note
To get an acoustic warning if you exceed the required speed, the Speed Limit Warning function must be activated and the Road Sign Audio Warning subfunction must be set to On. An acoustic warning is then given if the car’s speed exceeds the speed indicated by the Road Sign Information function in the driver display.
Warning for speed camera
A car equipped with Road Sign Information and map data(Option/accessory) can provide information on an upcoming speed camera in the driver display(Option/accessory).
If the car exceeds a detected speed limit with the Speed warning function activated, a speed warning is given when the car approaches a speed camera, provided that the navigation map for the area in question contains information on speed cameras.
Note
An option is available to receive an acoustic warning for speed cameras independently of the car’s speed and exceeded speed limit, even if the Road Sign Audio Warning function is deactivated.
Activating and deactivating warnings from road sign information
(Option/accessory)
The driver can choose which warnings are activated for Road Sign Information and adjust the limit for them.
Select in the centre display’s top view.
Select Speed Limit Warning and the desired settings.
You can choose to do the following:
- Activate speed warning
- Adjust the limit for Speed Warning(Option/accessory)
- Activating acoustic warning in connection with speed warning
- Activating acoustic warning in connection with speed camera warning(Option/accessory)
Display mode for road sign information
(Option/accessory)
The Road Sign Information function shows road signs in different ways depending on the sign and the situation. The following illustrations are examples.
Example(Option/accessory) of detected speed information.
When the function detects a road sign with an imposed speed limit the driver display shows the sign as a symbol combined with a coloured indication on the speedometer.
If the car is equipped with map data(Option/accessory), speed-related information is also obtained from map data, which means that the driver display can show or change information on the speed limit without having passed a speed-related sign.
An additional sign, such as “no overtaking”, may be shown together with the speed limit symbol.
Speed limit or end of motorway
When the function detects an “indirect speed limit sign” stating the end of the current speed limit – e.g. at the end of a motorway – a symbol appears with the corresponding road sign in the driver’s display.
If the car is equipped with map data(Option/accessory), direct speed limit signs are normally displayed – indirect speed limit signs are only displayed if map data has no information on the speed limit for the road section in question.
Example of indirect speed limit sign:
End of all restrictions.
End of motorway.
The symbol in the driver display extinguishes shortly after and is re-illuminated when the speed-related sign has been passed.
Changed speed limit
When passing a direct speed limit sign when a speed limit changes a symbol with the corresponding road sign appears in the driver’s display.
Example of direct speed limit sign.
The symbol in the driver display extinguishes after a while and is re-illuminated when the speed-related sign has been passed.
If the car is equipped with map data(Option/accessory), speed limit signs are shown in the driver display when map data contains information on the speed limit for the road section in question, even if no direct sign has been passed. If there is no information in the map data, the sign is extinguished after a while.
Additional signs
Examples of additional signs.
Sometimes different speed limits are signed 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.
If a trailer is connected to the car’s electrical system and you pass a speed sign with the additional sign “trailer”, the indicated speed will appear on the driver display.
Some speed limits only apply after a certain distance or at a certain time of day. The driver’s attention can be drawn to this fact by means of a symbol for an additional sign below the speed symbol.
The additional symbol in the driver display will show either “DIST” or “TIME”.
Sign for “School” and “Children at play”
If a warning sign for “School” or “Children at play” is included in the map data(Option/accessory), the driver display shows a sign of this type.
