The steering assistance provided by the electromechanical steering system automatically adjusts to
the vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
functions only when the engine is running.
You will need considerably more strength than normal to steer the vehicle if the power steering is
reduced or has failed completely.
Counter steering assistance
Counter steering assistance provides the driver with steering assistance in critical driving situations.
Additional steering forces assist the driver when counter steering ⇒ .
Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the steering response in a
driving situation. Progressive steering functions only when the engine is running.
In urban traffic, less steering input is required when parking, manoeuvring, or turning sharply.
When driving on country roads or on the motorway, the progressive steering provides a more
sporty, direct steering response, and a dynamic feel.
WARNING
If the power steering is not working, the steering wheel is difficult to turn, which makes it difficult to
steer the vehicle.
Depending on the vehicle equipment level, the power steering functions only when the engine is
running.
Never allow the vehicle to roll if the engine is switched off.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering column lock
may be activated and it will no longer be possible to steer the vehicle.
WARNING
In conjunction with the ESC, counter steering assistance provides the driver with assistance when
steering in critical driving situations. The driver must steer the vehicle at all times. Counter steering
assistance does not steer the vehicle.
NOTICE
When the vehicle is towed, the ignition must be switched on to prevent the steering wheel from
locking, and so that the turn signals, horn, wipers and window washer system can be used.
Troubleshooting
Steering requires increased force
The indicator lamp lights up yellow.
The steering should be checked by a qualified workshop as soon as possible.
If the yellow warning lamp remains off after the engine has been restarted and you have driven a
short distance, you do not need to consult a qualified workshop.
Fault in steering
The indicator lamp lights up yellow.
The 12-volt vehicle battery was disconnected.
Drive a short distance at a speed of 15 – 20 km/h (9 – 12 mph).
If the yellow warning lamp is still lit after the engine has been restarted, have the steering checked
by a qualified workshop immediately.
Fault in steering
The indicator lamp flashes yellow.
Turn the steering wheel back and forth.
Switch the ignition off and then on again.
Observe the messages on the instrument cluster display.
Do not continue your journey if the indicator lamp still flashes when the ignition is switched on.
Seek expert assistance.
Steering column is not unlocked or locked
The indicator lamp flashes yellow.
Follow any messages that are on the instrument cluster display.
Switch the ignition off and then on again.
Do not continue your journey if the steering column remains locked when the ignition is switched
on.
Seek expert assistance.
Steering requires increased force
The warning lamp lights up red.
The electromechanical steering has failed.
Do not drive on!
Seek expert assistance.

WARNING
The vehicle handling may change as a result of the different driving profiles. Never allow driving
profile selection to tempt you into taking any risks when driving.
Always adapt your speed and driving style to the current visibility, weather and road or traffic
conditions.
In vehicles with a DSG® dual clutch gearbox, the system automatically changes to gear position S
when the Sport driving profile is selected. The system automatically change to gear position D when
the Eco driving profile is selected. Since coasting is active in the Eco driving profile, the gearbox

Overtaking
If you indicate left (left-hand traffic: indicate right) to overtake, ACC will accelerate the vehicle and
reduce the distance from the vehicle in front. Your set speed will not be exceeded.
If ACC does not detect any vehicle in front after you have changed lane, ACC will accelerate the
vehicle up to the set speed.
Stop-and-go traffic
ACC can brake vehicles with DSG® dual clutch gearbox to a standstill and hold them stationary. ACC
remains active and the instrument cluster display shows ACC ready for a few seconds. During this
time the vehicle will move off again automatically as soon as the vehicle in front moves off
(depending on the vehicle equipment level and not available in all countries).
Press the button.
Press the button or briefly press the accelerator.
The vehicle is stationary for longer than approximately three minutes.
A vehicle door is opened.
The ignition is switched off.
Avoiding overtaking on the right (left-hand traffic: overtaking on the left)
If ACC detects a slower vehicle in the left-hand lane (left-hand traffic: in the right-hand lane), ACC
will brake the vehicle gently within the system limits and therefore prevent a prohibited overtaking
manoeuvre ⇒ Fig. 118 . The function is active from speeds of around 80 km/h (50 mph), but is not
available in all countries.
WARNING
If the message ACC ready is shown on the instrument cluster display and the vehicle in front moves
off, your vehicle will move off automatically. In some cases the radar sensor may be unable to detect
obstacles that are located in the vehicle's path. This can result in serious injury and accidents.
Always check the road ahead before moving off and brake the vehicle if necessary.
Limits of ACC
WARNING
Failure to switch off Front Assist in the situations mentioned can result in accidents and serious
injuries.
Pedestrian Monitoring
First read and observe the introductoryinformation and safety warnings⇒Introduction
Pedestrian Monitoring can help to avoid accidents with pedestrians crossing the vehicle's path or to
mitigate the consequences of an accident.
The system gives a warning when there is a risk of collision, prepares the vehicle for emergency
braking, helps to brake the vehicle or performs an automatic brake intervention. In the event of an
advance warning, the warning lamp lights up in the instrument cluster
When Front Assist is switched on, Pedestrian Monitoring is active as part of Front Assist in a vehicle
speed range from approx. 5 km/h (3 mph) to 65 km/h (40 mph).
Pedestrian Monitoring is not available in all countries, depending on the vehicle equipment level.
WARNING
The intelligent Pedestrian Monitoring technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by the
Pedestrian Monitoring system tempt you into taking any safety risks when driving. The driver is
always responsible for braking in time.
If Pedestrian Monitoring issues a warning, brake your vehicle immediately depending on the traffic
situation or avoid the pedestrian.
Pedestrian Monitoring cannot prevent accidents and serious injuries on its own.
Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking
interventions in complex driving situations, e.g. on a main road that turns sharply.
Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking
interventions when its function is impaired, e.g. if the radar sensor is covered or its position has
been changed.
Be prepared to take over control of the vehicle yourself at all times.
Operating the area monitoring system (Front Assist)
First read and observe the introductoryinformation and safety warnings⇒Introduction
Front Assist and the advance warning (in some countries) are automatically switched on when you
switch on the ignition.
However, the system is not available or its functions are restricted for a period of around 30 seconds
(also longer, depending on the driving situation).
