Traction Control (TC)
This function is designed to help reduce wheel spin at low speeds by transferring power from adrive wheel that begins to lose traction to thewheel on the opposite side of the vehicle (on thesame axle).
Spin Control (SC)
The SC function is designed to help prevent the drive wheels from spinning while the vehicle isaccelerating.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one ormore of the wheels if the vehicle shows a ten-dency to skid or slide laterally.
Corner Traction Control (CTC)
CTC compensates for understeering and helps provide additional stability when acceleratingthrough a curve by preventing the inside wheelfrom spinning. This is particularly useful whenaccelerating on a curving highway on-ramp. CTC is most effective if the stability system's Sport mode is selected. See the section about
Sport mode.
Engine Drag Control (EDC)
EDC helps keep the engine running if the wheels show a tendency to lock, e.g., when shifting downin the Geartronic manual shifting mode or whileusing the engine's braking function on a slippery surface. If the engine were to stop, power steer-ing would not function, making the vehicle moredifficult to steer.
Trailer Stability Assist (TSA)
1
The TSA helps stabilize a vehicle that is towing a trailer when the vehicle and trailer have begun tosway. See Trailer Stability Assist (TSA) (p. 282)for more information. This system is automatically deactivated if the driver selects
Sport mode.

Stability system – operation
Operation
Sport mode
The stability system is always activated and can- not be switched off.
However, the driver can select Sport mode, which offers more
active driving characteristics. Sport mode can be selected in
the MY CAR menus, see My Car – introduction (p. 77).
In Sport mode, the engine management system
monitors movement of the accelerator pedal and steering wheel for sportier driving by allowingmore lateral movement of the rear wheels beforeESC is activated. Under certain circumstances, such as when driv- ing with snow chains, or driving in deep snow orloose sand, it may be advisable to temporarily use Sport mode for maximum tractive force.
If the driver releases pressure on the accelerator pedal, ETC will also activate to help stabilize thevehicle. To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is

–Press the
CRUISE button (1).
> The symbol
illuminates and the text(---) mph (5) indicates that cruise control
is in standby mode.
NOTE
Putting cruise control in standby mode does not set a cruising speed.
Setting a speed
Use the or buttons set the vehicle's cur-
rent 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 but-
ton 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 button whenyou have reached the desired speed.
NOTE
• A temporary increase in speed by press- ing the accelerator pedal, for less than1 minute (e.g. when passing another car),does not affect the current cruise controlsetting. The vehicle will automaticallyreturn to the previously set speed whenthe accelerator pedal 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 off inorder to reset cruise control.

Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval to the vehi-cle ahead.
Switching from ACC to CCThis may be useful if, for example, the radar sen- sor is obstructed in some way. See AdaptiveCruise Control – limitations (p. 194) for addi-tional information.
• Press and hold the
button; the symbol in
the instrument panel will switch from

> This activates the standard cruise control function (see Cruise control (CC) – introduc- tion (p. 181)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automatically
maintain a set distance to a vehicle ahead.
• Only the set speed will be maintained andthe driver will have to apply the brakeswhen needed.
Switching from CC to ACC
Switch off cruise control by pressing once or
twice as needed according to the instructions in

Cruise control (CC) – deactivating Cruise control is designed to assist the driver by maintaining a set speed. It is primarily intendedfor use on long straight roads in steady traffic,such as on highways and other main roads.
Automatic deactivationThe cruise control is automatically deactivated temporarily
if one of the following occurs:
• If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to position
N.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased by usingthe accelerator pedal for more than 1 minute.
• Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the sys-tem's memory.
Temporary deactivationThe driver can temporarily deactivate the cruise control by pressing 0. The saved speed is shown
in brackets in the information display.
Resume set speedIf the cruise control has been deactivated tempo- rarily, it can be reactivated by pressing
. The
vehicle's speed returns to the most recently set speed.
WARNING
There may be a significant increase in speed after the
button has been pressed.
Deactivation
The Cruise control is disengaged by pressing or by switching off the engine. The set speed is cleared.
WARNING
Cruise control should not be used in heavy traffic or when driving on wet or slipperyroads. Cruise control may not maintain setspeed on steep downgrades.

WARNING
•
Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible for applying the brakes if thesystem does not detect another vehicle.
• Adaptive Cruise Control does not react topeople or animals, or small vehicles suchas bicycles and motorcycles. It also doesnot react to slow moving, parked orapproaching vehicles, or stationaryobjects.
• Do not use Adaptive Cruise Control indemanding driving conditions such as citydriving or other heavy traffic situations, inslippery conditions, when there is a greatdeal of water or slush on the road, duringheavy rain or snow, in poor visibility, onwinding roads or on highway on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes.Do not rest your foot under the brake pedal.
The ACC system is designed to smoothly regu- late speed. However, the driver must apply thebrakes in situations that require immediate brak-ing. This applies when there are great differencesin speed between vehicles, or if the vehicle aheadbrakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not at all, seeAdaptive Cruise Control – limitations (p. 194).
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if thevehicle's speed falls below 18 mph (30 km/h) orif engine speed (rpm) becomes too low, ACC dis-engages (goes into standby mode) and will nolonger modulate the brakes. The driver will thenhave to maintain a safe distance to the vehicleahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off completely, thebrakes will not be modulated automatically.The driver must assume full control over thevehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situationsrequiring more brake force than ACC can provideand if the driver does not apply the brakes, anaudible signal from the Collision Warning systemwill sound and warning light will illuminate (see Collision warning * – function (p. 212)) in the
windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Adaptive Cruise Control – setting speed
Setting a speedOnce ACC has been put in standby mode:
Controls and display
Put in active mode and set a speed (each additional press increases/decreases speedby 1 mph (approximately 2 km/h))
• Press
or (4).
> The set speed, for example 60 mph (5), will be magnified for several seconds and the frame around the speed will change colors from white to green to indicate that this
speed has been stored (set).
When this symbol has changed colorsfrom white to green , ACC is in active
mode and the vehicle will maintain the
set speed.
This symbol indicates that you are approaching a vehicleahead. ACC will switch from maintain- ing a set speed to maintaining
a set distance from that vehi-
cle.
When this happens, a speed range will be indicated on the
speedometer: The higher speed (the cur-
rently set speed (5)) will be marked in green.
The lower speed in the range is the speed of the
vehicle ahead.
Changing the set speed
• After a speed has been set, it can be increased or decreased by briefly pressing the
or buttons. Each time one of
these buttons is pressed, the vehicle's speed changes by 5 mph or 5 km/h. If the speed isincreased by pressing the accelerator pedal,the vehicle's speed when the button ispressed will be set.
• Press and hold one of these buttons toincrease/decrease the speed in 1-mph or 1-km/h increments. Release the button whenyou have reached the desired speed.
NOTE
•
If one of the Adaptive Cruise Control but- tons is pressed for more than approxi-mately one minute, ACC will be deacti-vated. The engine must then be switchedoff and restarted to reset ACC.
• In some situations Adaptive Cruise Con- trol cannot be put in active mode.

WARNING
The vehicle may accelerate quickly after has been pressed if its current speed is con- siderably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regulate
the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passing anothervehicle, ACC is deactivated temporarily and isreactivated when the pedal is released.
Automatic standby modeACC is linked to other systems such as the sta- bility system. If this system is not functioningproperly, ACC will switch off automatically. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled
is shown in the instrument
panel. The driver must then intervene and adapt the vehicle's speed to the surrounding traffic andregulate the distance to the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph(30 km/h)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, for exam-ple, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactivated by pressing the
button on the steering wheel
keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after has been pressed if its current speed is con- siderably lower than the set speed.
