Active chassis - Four C*
Active chassis "Four-C" (Continously Controlled Chassis Concept), regulates thecharacteristics of the shock absorbers so thatthe car's driving characteristics can beadjusted. There are three settings: Comfort,
Sport and Advanced .
ComfortThis setting means that the car is perceivedas being more comfortable on rough anduneven road surfaces. Shock absorption issoft and the movement of the body is smoothand gentle.
SportThis setting means that the car is perceivedas being more sporty and is recommendedfor more active driving. Steering response isfaster than in the Comfort mode. Shockabsorption is harder and the body follows theroad in order to reduce rolling during corner-ing.
AdvancedThis setting is only recommended on veryeven and smooth road surfaces. The shock absorbers are optimised for maxi- mum roadholding and rolling in bends is fur-ther minimised.
Operation
Control buttons.
The required chassis setting is selected using the centre console buttons. The setting usedwhen the engine was switched off is re-acti-vated when the engine is next started. Theexception is Advanced - it is restarted asSport.
Stability and traction control system (DSTC)
The stability and traction control system, DSTC (Dynamic Stability & Traction Control),helps the driver to avoid skidding andimproves the car's traction. The activation of the system during braking may be noticed as a throbbing sound. Thecar may accelerate slower than expectedwhen the accelerator pedal is depressed. The system consists of the following func- tions: • Active Yaw Control
• Spin Control
• Traction control system
• Engine drag control - EDC
• Corner Traction Control - CTC
• Trailer Stability Assist* - TSA
Active Yaw ControlThe function checks the driving and brake force of the wheels individually in order tostabilise the car.
Spin ControlThe function prevents the driving wheels fromspinning against the road surface duringacceleration.

Traction control systemThe function is active at low speed and trans- fers power from the driving wheel that is spin-ning to the one that is not.
Engine drag control (EDC)EDC (Engine Drag Control) prevents involun-tary wheel locking, e.g. after shifting down orengine braking when driving in low gears onslippery road surfaces. Involuntary wheel locking while driving can, amongst other things, impair the driver's abil-ity to steer the car.
Corner Traction Control (CTC)*CTC compensates for understeer and allowshigher than normal acceleration in a bendwithout wheelspin on the inner wheel, e.g. onan arcing motorway entrance road to quicklyreach the prevailing traffic speed.
Trailer Stability Assist 1Trailer stability assist (p. 312) function is tostabilise the car and trailer combination if itbegins to snake. For more information, seeDriving with a trailer (p. 306).
NOTE
The function is deactivated if the driver selects
Sport mode.

Stability and traction control system (DSTC) - operation
The stability and traction control system (p. 175) (DSTC - Dynamic Stability & TractionControl), helps the driver to avoid skiddingand improves the car's traction.
Selection of level - Sport modeThe stability and traction control system isalways activated - it cannot be switched off. However, the driver can select the
Sport
mode, which allows for a more active driving experience. In Sport mode the system
detects whether the accelerator pedal, steer-ing wheel movements and cornering are moreactive than in normal driving and then allowscontrolled skidding with the rear section up toa certain level before it intervenes and stabil-ises the car. If the driver interrupts a controlled skid by releasing the accelerator pedal then the sta-bility and traction control system intervenesand stabilises the car. With Sport mode, maximum traction is
obtained if the car has become stuck, or when driving on a loose surface - e.g. sand ordeep snow. Sport mode is selected in the menu system
MY CAR. For a description of the menu sys- tem, see MY CAR (p. 103).

Road Sign Information (RSI)*
The road sign information function (RSI – Road Sign Information) helps the driver toremember which speed-related road signs thecar has passed.
Examples of readable speed related signs 2
.
The RSI function gives information on current speed, e.g. that a motorway or road is star-ting/ending and when overtaking is prohibi-ted. If both a sign for motorway/road for motor- ised traffic and a sign showing the maximumpermitted speed are passed, RSI decides toshow the sign symbol for maximum permittedspeed.
WARNING
RSI does not work in all situations but is designed merely as a supplementary aid. The driver always bears ultimate responsi- bility for ensuring that the vehicle is drivensafely and that applicable road traffic rulesand regulations are followed.

.
When RSI has recorded a road sign with an imposed speed, the combined instrumentpanel displays the sign as a symbol.
Together with the symbol forthe current speed limit, asign showing that overtakingis prohibited may also bedisplayed where appropriate.

End of restriction or motorwayA corresponding road sign is shown in the combined instrument panel forapprox. 10 seconds in situations where RSIdetects a sign that involves the end of aspeed limit - or other speed-related informa-tion, e.g. end of a motorway. Examples of such signs are:
End of all restrictions.
End of motorway. Following which, the sign information is hid- den until the next speed-related sign isdetected.
Additional signs
Examples of additional signs3
.
Sometimes different speed limits are signpos- ted for the same road - an additional signthen indicates the circumstances under whichthe different speeds apply. The road sectionmay be particularly susceptible to accidentsin 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 anexit is indicated in certainmarkets by means of anadditional sign containing anarrow. 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 situationby means of a symbol for an additional signunder the symbol showing speed.
Display of additional information
A symbol for additional sign in the form of an empty frame under the combined instrumentpanel's speed symbol means that the RSI hasdetected an additional sign with supplemen-tary information for the current speed limit.
Setting in MY CARThere are options for RSI in the MY CAR
menu system; see MY CAR (p. 103).

Road sign information (RSI)* - limitations
The road sign information function (RSI – Road Sign Information) helps the driver toremember which speed-related road signs thecar has passed. The function has the follow-ing limitations. The RSI function's camera sensor has limita- tions just like the human eye - read moreabout camera sensor limitations (p. 220)). Signs which indirectly provide information on a prevailing speed limit, e.g. name signs fortowns/districts, are not recorded by the RSIfunction. Here are several examples of what can dis- rupt the function:
• Faded signs
• Signs positioned on bends
• Rotated or damaged signs
• Concealed or poorly positioned signs
• Signs completely or partly covered with frost, snow and/or dirt.
