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.

Deactivating/reactivating the speed limiter
The speed limiter (Speed Limiter - SL) can be temporarily deactivated so that it is set in thestandby mode and can be reactivated later.
NOTE: The illustration is schematic - details may vary depending on car model.
Deactivate the speed limiter and set it
in standby mode
–Press the steering wheel button (2).
> The speed limit markings and symbols in the driver display change colour from WHITE to GREY - the speed limiter is nowtemporarily deactivated and the driver canexceed the maximum speed setting.
Reactivating the speed limiter from standby mode
–Press the steering wheel button (1).
> The driver display's speed limit markings change colour from GREY to WHITE - the car's speed is then limited again by thelast stored maximum speed.
or
–Press the steering wheel button (2).
> The speed limiter indicators and symbols in the driver display change colour from GREY to WHITE — the car will now applyits current speed as the maximum speed.
Temporary increase in speed with the accelerator pedal
The speed limiter can also be temporarily overrid- den with the accelerator pedal without the speedlimiter being set in standby mode - e.g. to be ableto quickly accelerate the car out of a situation. Inwhich case, proceed as follows:
1. Fully depress the accelerator pedal and release it so that acceleration is interrupted when the desired speed has been reached.
> In this case, the speed limiter is still acti-vated and the driver display's symbol is therefore WHITE.
2. Fully release the accelerator pedal when the temporary acceleration is finished.
> The car is then braked automaticallybelow the last stored maximum speed.

Automatic speed limiter *
The automatic speed limiter (Automatic Speed
Limiter - ASL) function helps the driver to adaptthe car's maximum speed to the speed shownon the road signs.
The speed limiter function (Speed Limiter — SL) can be changed to automatic speed limiter. The automatic speed limiter uses speed informa- tion from the Road Sign Information 3
function to
automatically adapt the car's maximum speed.
WARNING
The automatic speed limiter function is an aid, and does not work in all driving situations,traffic, weather and road conditions. The driveralways bears responsibility for maintaining thecorrect distance and speed, as well as whenthe automatic speed limiter is being used. Even if the driver clearly sees the speed-rela- ted road sign, the speed from the Road signinformation function many be incorrect - insuch cases the driver must intervene him/herself and accelerate or brake to a suitablespeed. See also the heading "Limitations for Road sign information".
Is SL or ASL active?Symbols in the driver display show which speed limiter function is active:

The ASL symbol
The sign symbol (displayed alongside the stored speed, "70", in the centre ofthe speedometer) can be shown inthree colours with the following mean-
ings:

For example, scanning of a sign failed.
Limitations of ASLAutomatic speed limitation takes place using speed information from the RSI 3
function - not
from the speed limit road signs that the car passes. If RSI 3
cannot interpret and provide speed infor-
mation to the ASL, then the ASL is set in standby mode and changes over to SL. In such cases thedriver must intervene and brake to a suitablespeed. The ASL will be reactivated when the RSI 3
func-
tion can once again interpret and provide speed information to the ASL. See also the heading "Limitations for Road Sign Information".

Deactivating/reactivating the cruise control The cruise control (Cruise Control - CC) can be temporarily deactivated so that it is set in thestandby mode and can be reactivated later.
NOTE: The illustration is schematic - details may vary depending on car model.
Deactivate Cruise Control and set in
standby mode
–Press the steering wheel button (2).
> The speed limit markings and symbols in the driver display change colour from WHITE to GREY — Cruise Control is nowtemporarily deactivated and the driver cantemporarily exceed the set speed.
Standby mode on driver intervention
The cruise control is temporarily deactivated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position
• the clutch pedal is held depressed for longerthan 1 minute
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
The driver must then control the speed himself/herself. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Cruise control is temporarily disengaged and set in standby mode if:
• wheels lose traction
• engine speed is too low/high
• brake temperature is too high
• speed falls below 30 km/h (20 mph).
The driver must then control the speed himself/herself.
