Speed-dependent steering force Speed related power steering causes the steer- ing wheel force to increase with the speed of thecar in order to give the driver enhanced sensitiv-ity.
On motorways the steering feels firmer. When parking and at low speed steering is light andrequires only a slight effort.
NOTE
In certain situations the power steering may become too hot and then needs to be tempo-rarily cooled - during this time the powersteering operates with reduced power andturning the steering wheel may then be per-ceived to be slightly heavier. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage.
Change the steering force level *To select the steering force level, go to the "Drive modes" section and see the description at thealternative INDIVIDUAL under the heading"Selectable drive modes". For the car models without a drive mode control with its INDIVIDUAL option, the selection ofsteering force is instead made via the centre dis-play's top view and the following search path:

Roll Stability Control Roll Stability Control (RSC) is a stabiliser sys- tem that minimises the risk of overturning, forexample during sudden evasive manoeuvres or ifthe car skids.
The RSC system registers if and how much the car's lateral inclination changes. This informationis used to calculate the risk of the car overturn-ing. If the car is at risk, its electronic stability con-trol system engages, the engine torque isreduced and one or more wheels are braked untilthe car has regained its stability.
WARNING
Under normal driving conditions, the RSC sys- tem improves the car's road safety, but thismust not be taken as a reason to increasespeed. Always follow the normal precautionsfor safe driving.

Symbols and messages for electronic stability control
A number of symbols and messages regarding electronic stability control (Electronic Stability Control -ESC) can be shown on the driver dis-play.
The following table shows some examples.
Symbol
Message Specification
Constant glow for approx. 2 seconds. System check when the engine is started.
Flashing light. ESC system is being activated.
Constant glow. Sport mode is selected.
NOTE: The ESC system is not deactivated in this mode — it is partly reduced.
ESC Temporarily offESC system has been temporarily reduced due to excessive brake temperature - the function is reactiva- ted automatically when the brakes have cooled.
ESC Service requiredESC system disengaged.
• Stop the car in a safe place, switch off the engine and start it again.
• Visit a workshop if the message remains - an authorised Volvo workshop is recommended.

Speed limiter *
A speed limiter (Speed Limiter — SL) can be regarded as a reverse cruise control — thedriver regulates the speed using the acceleratorpedal but is prevented by the speed limiter fromaccidentally exceeding a pre-selected/presetmaximum speed.

WARNING
The Speed Limiter is an aid and cannot deal with all traffic, weather and road conditions. The driver must always pay attention to traffic conditions and take action when the SpeedLimiter is not maintaining a suitable speed. The driver always has the ultimate responsibil- ity for the car being driven safely and inaccordance with applicable traffic rules andregulations, even when the Speed Limiterfunction is in use.

Activating and starting the speed limiter
The speed limiter function (Speed Limiter - SL) must first be selected and activated in order tobe able to regulate the speed.
Activate the speed limiter
NOTE: The illustration is schematic - details may vary depending on car model.
–Press ◀ (1) or ▶ (3) to browse to the sym-
bol/function
(4).
> The symbol is shown and the speed lim- iter can then be activated.
Start the speed limiterThe lowest maximum speed that can be stored is 30 km/h (20 mph).
–With the symbol/function displayed,
press the steering wheel button
(2).
> The speed limiter starts and the current speed is stored as the maximum speed.

Managing speed for the speed limiter
The speed limiter (Speed Limiter - SL) can be set to different speeds.
NOTE: The illustration is schematic - details may vary depending on car model.
–Change the stored maximum speed with short or long presses on the steering wheel button
(1) or - (3):
• Use
short presses to adjust +/- 5 km/h
(+/- 5 mph) with each press.
• Hold the button depressed
to adjust
+/- 1 km/h (+/- 1 mph) and release
when the driver display's marking (4)/(6) is at the desired speed .
> The speed set after the last press is stored in the memory.
