Active chassis* (Four C)
Active chassis, Four-C (Continuously Controlled Chassis Concept), regulates thecharacteristics of the shock absorbers so thatthe vehicle's driving characteristics can beadjusted. There are three settings: Comfort,Sport and Advanced.
Operation
Chassis settings
Use the buttons in the center console to change setting. The setting in use when theengine is switched off is activated the nexttime the engine is started.
NOTE
This system is available on Canadian mod- els only.
ComfortComfort mode offers a somewhat softer ride and the transmission shifts gears at lowerrpm. This mode is particularly suitable forlong-distance highway driving. The indicatorlight in the button will be on when this modeis selected.
SportIn this mode, the vehicle's body sway is reduced during cornering and steeringresponse is more immediate. The transmis-sion shifts up at higher rpm for sportier driv-ing. The indicator light in the button will be onto indicate that Sport mode has beenselected.
AdvancedIn this mode, body sway in curves is minimal and steering response is very direct. Gearshifting is done at high rpm in each gear fordynamic and active driving.

Stability system – introduction
The Electronic Stability Control (ESC) system consists of a number of functions designed tohelp reduce wheel spin, counteract skiddingand to generally help improve directional sta-bility.
A pulsating sound will be audiblewhen the system is actively operat-ing and is normal. Acceleration willalso be slightly slower than normal.
WARNING
ESC is a supplementary aid and cannot deal with all situations or road conditions. The driver is always responsible for oper- ating the vehicle in a safe manner inaccordance with current traffic regulations.
ESC consists of the following functions:
• Traction control
• Spin control
• Active Yaw Control
• Trailer Stability Assist
Traction Control (TC)This function is designed to help reduce wheel spin at low speeds by transferringpower from a drive wheel that begins to losetraction to the wheel on the opposite side ofthe vehicle (on the same axle).

Spin Control (SC)The SC function is designed to help prevent the drive wheels from spinning while the vehi-cle is accelerating.
Active Yaw Control (AYC)This function helps maintain directional stabil- ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally.
Trailer Stability Assist (TSA)1The TSA helps stabilize a vehicle that is tow- ing a trailer when the vehicle and trailer havebegun to sway. See Trailer Stability Assist(TSA) (p. 283) for more information. This system is automatically deactivated if the driver selects
Sport mode.

Stability system – operation
Operation
Sport modeThe stability system is always activated and cannot be switched off.
However, the driver canselect Sport mode, which
offers more active drivingcharacteristics. Sport mode can be selected
in the MY CAR menus, see
My Car – introduction (p. 76).
In Sport mode, the engine management sys-
tem monitors movement of the accelerator pedal and steering wheel for sportier drivingby allowing more lateral movement of the rearwheels before ESC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, ETC will also activate to help sta-bilize the vehicle. To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. ETC will return to normal mode when the engine is restarted.

Adjustable steering force*
Steering force increases with the speed of the vehicle to give the driver enhanced sense ofcontrol and stability. At low speed the vehicleis easy to steer in order to facilitate parking,etc.

NOTE
This steering force level menu function cannot be accessed when the vehicle is inmotion.
NOTE
In certain situations, the power steering may become too warm and will have to betemporarily cooled down. While this ishappening, the power steering effect willbe reduced slightly and somewhat moreeffort may be required to turn the steeringwheel. If this occurs, a message will be displayed in the instrument panel.

Road Sign Information (RSI)* – introduction
RSI is a feature that helps the driver see road signs with the posted speed limit.
Introduction
Examples of readable road signs If the vehicle passes a sign showing the speed limit, this will be displayed in the centerconsole.

Road Sign Information (RSI) – limitations
RSI's camera has the same limitations as the human eye. See The camera’s limitations(p. 217) for more information about the cam-era's limitations. Signs that indirectly indicate the speed limit (such as a sign with a town's name and thepermitted speed limit) will not be registeredby RSI. Other factors that may interfere with RSI include:
• Faded signs
• Signs located in a curve
• Twisted or damaged signs
• Obstructed signs
• Signs that are partially covered by snow, ice, etc.

Use the or buttons set the vehicle's
current speed. The set speed is shown in the display.
NOTE
Cruise control cannot be engaged at speeds below 20 mph (30 km/h).
Adjusting the set speedAfter a speed has been set, it can be increased or decreased by using the
or buttons. 1. Press
or briefly and release the
button to increase or decrease vehicle speed by approximately 1 mph or 1 km/h.
> This will become the set speed when the button is released.
2. Press and hold one of these buttons to increase/decrease the speed in 1-mph or 1-km/h increments. Release the buttonwhen you have reached the desiredspeed.
NOTE
•A temporary increase in speed by pressing the accelerator pedal, for lessthan 1 minute (e.g. when passinganother car), does not affect the cur-rent cruise control setting. The vehiclewill automatically return to the previ-ously set speed when the acceleratorpedal is released.
• If one of the cruise control buttons iskept depressed for more than approx.1 minute cruise control is disengaged.The engine must then be switched offin order to reset cruise control.
