Introduction
Front Assist has physical and system-related limitations. From the driver's perspective, some Front
Assist reactions may therefore occur unexpectedly or with a delay in certain circumstances. You
should therefore always be prepared to take full control of the vehicle if necessary.
•In tight bends.
•If the accelerator is fully depressed.
•If Front Assist is switched off or faulty.
•If TCS is switched off manually.
•If ESC is taking corrective action.
•If there is a fault in several brake lights on the vehicle or on a trailer with an electrical
connection to the vehicle ⇒.
•If the radar sensor is dirty or covered.
•If there are metal objects, e.g. tracks in the road or metal plates used in roadworks, or road
signs, above and adjacent to the road.
•If the vehicle is reversing.
•Under hard acceleration.
•In snow or heavy rain.
•In case of narrow vehicles, e.g. motorbikes.
•If vehicles are travelling slightly to the left or right of your vehicle.
•If vehicles are crossing in front of your vehicle.
•If there is oncoming traffic.
•If pedestrians are standing in front of the vehicle, approaching the vehicle, or moving in the
same direction as the vehicle.
•In complex driving situations, e.g. at traffic islands.
•In unclear traffic situations, e.g. vehicles ahead are heavily braking or turning off.
•When loads or attachment parts on other vehicles protrude to the side, rear or above the normal
dimensions of the vehicle.
Switching off Front Assist
•If the vehicle is being towed.
•If the vehicle is on a rolling road test bed.
•If the vehicle is driven in areas other than public roads.
•If the radar sensor is faulty.
•After external force on the radar sensor, e.g. after a rear-end collision.
•In the event of multiple unwanted interventions.
•If the radar sensor is covered temporarily by any auxiliary equipment, e.g. auxiliary headlights.
•If the vehicle is loaded onto a truck, car ferry or motorail train.
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 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.
•The Pedestrian Monitoring system cannot prevent accidents and serious injuries on its
own.
•The Pedestrian Monitoring system can issue unnecessary warnings and carry out
unwanted braking interventions in complex driving situations, e.g. on a twisting main
road.
•The Pedestrian Monitoring system 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.
WARNING
Failure to switch off Front Assist in the situations mentioned can result in accidents and
serious injuries.
WARNING
In the following driving situations, the yellow indicator lamp lights up in the housing of the respective
exterior mirror:
•If your vehicle is being overtaken.
•When overtaking another vehicle with a speed difference of up to approximately 15 km/h
(9 mph). No display will be shown if the takeover manoeuvre is much faster.
The yellow indicator lamp flashes if a possible critical situation is detected when you indicate in the
direction of the detected vehicle.
The quicker another vehicle approaches, the earlier there is a corresponding display in the exterior
mirror.
Lane change system Side Assist Plus
If the vehicle is equipped with a lane keeping system and the system is switched on, the driver is
warned by a corrective steering intervention when changing lanes during a possible critical situation
(information level, warning level). The steering intervention also occurs when the turn signal is
activated for the corresponding direction. If the steering intervention is overridden by the driver, the
steering wheel vibrates to give an additional warning.
Automatic deactivation
The lane change system will switch off automatically if the radar sensors are permanently covered.
This can be caused by a layer of ice or snow in front of the radar sensor, for example.
A text message will be shown on the instrument cluster display.
If the lane change system sensor has been automatically deactivated, the system cannot be
activated until the ignition has been switched off and back on again.
The lane change system and Rear Traffic Alert are switched off automatically when the factory-
fitted towing bracket is electrically connected with a trailer or similar ⇒ Trailer towing. The lane
change system and Rear Traffic Alert are automatically switched on again when the trailer is
unhitched from the vehicle. The lane change system and Rear Traffic Alert must be switched off
manually if a non-factory-fitted towing bracket is used.
Brightness
The brightness of the visual display will automatically adapt to the light levels.
The basic brightness level can be set in the Infotainment system ⇒ Operation and display in the
Infotainment system.
The lane change system is not active during the setting procedure.

The electronic parking brake switches off automatically if one of the following situations occurs
when the driver door is closed:
•In vehicles with a DSG dual clutch gearbox: engage or change a position.
•In vehicles with a manual gearbox: fully depress the clutch before pulling off.
Moving off on steep uphill gradients or with increased vehicle weight
You can prevent the electronic parking brake from switching off automatically by pulling the
button upwards and holding it while pulling away.
If higher engine power is required to move off, the electronic parking brake will be deactivated only
when you release the button.
This can make it easier to move off with a high trailer weight ⇒ Trailer towing.
Automatic switch-on of the electronic parking brake if not activated
properly when the driver leaves the vehicle
On vehicles with DSG dual clutch gearbox, the electronic parking brake may switch itself on
automatically if the system detects that the driver has not left the vehicle correctly.
Emergency braking function
The emergency braking function should only be used in those situations where the vehicle cannot
be stopped using the foot brake ⇒!
The vehicle will brake strongly as long as the button is pulled. A signal tone can be heard
at the same time.

Park Distance Control switches itself on automatically if the vehicle rolls backwards.
Depending on the vehicle equipment, Park Distance Control can also be activated automatically.
Switching off Park Distance Control
•Press the or button.
•OR: drive forwards at a speed of more than 10-15 km/h (6-9 mph).
•OR: move the selector lever to position P.
Automatic activation (depending on equipment)
Park Distance Control also switches itself on if the vehicle approaches an obstacle in the front area
of the vehicle at a speed of less than 15 km/h (9 mph). Automatic activation can be switched on in
the Infotainment system.
Automatic activation functions only when the vehicle speed falls below around 15 km/h (9 mph) for
the first time. Renewed automatic activation is possible after Park Distance Control has been
switched off and then back on again with the button or .
Automatic activation can also be reactivated by switching the ignition or electronic parking brake off
and then back on again.
Manoeuvre braking
If the vehicle is equipped with manoeuvre braking, the manoeuvre braking function triggers the
emergency brake as soon as an obstacle is detected while reversing. The manoeuvre braking
function helps to prevent collisions. The vehicle speed must not be higher than 10 km/h (6 mph).
The manoeuvre braking function is activated or deactivated when Park Distance Control is switched
on or off. The manoeuvre braking function is inactive for five metres after a braking operation in the
same direction of travel. The manoeuvre braking function is ready for braking again after changing
gear or position. The same restrictions apply as for Park Distance Control.
Manoeuvre braking is not active if Park Distance Control was activated automatically.
Touch the function button to switch manoeuvre braking on and off.

Rear view camera system (Rear View)
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching on and off
⇒ Display representation
⇒ Prerequisites
⇒ Parking perpendicular to the road (mode 1)
⇒ Parking parallel to the road (mode 2)
⇒ Troubleshooting
The rear view camera system in the
rear of the vehicle makes it easier for
the driver to see behind the vehicle and
provides support for parking
manoeuvres.
The rear view camera system shows the area behind the vehicle on the Infotainment system
screen. Depending on the operating mode, orientation lines support the view to the rear.
Modes for the rear view camera system
Depending on the vehicle equipment, the following operating modes are available:
•Perpendicular parking (mode 1): reverse parking perpendicular to the road.
•Parallel parking (mode 2): reverse parking parallel to the road.
•Trailer support (mode 3): support when hitching a trailer to the vehicle.
•Crossing traffic (mode 4): observing crossing traffic.
System limits
The rear view camera system shows only two-dimensional images on the screen. The lack of depth
of field means that potholes and protruding objects on the ground may only be detected with
difficulty, or may not be detected at all.
The rear view camera system may not always be able to detect objects such as thin rails, fences,
posts, trees etc. This could result in damage to your vehicle.
The system displays the orientation lines irrespective of the area surrounding the vehicle. There is
no automatic obstacle detection. Drivers must judge for themselves whether the vehicle will fit into
the parking space.
Switching on and off
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Switching on the rear view camera system
•Select reverse gear.
•OR: press the button.
Switching off the rear view camera system

Display representation
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The image of the rear view camera system is displayed in the Infotainment system.
The functions and displays depend on the vehicle equipment and may differ from each other.
The rear view camera system hides all orientation lines and guiding functions when the factory-
fitted towing bracket is electrically connected to the trailer ⇒ Trailer towing.
Settings
You can make settings by means of the function buttons when the rear view camera system is
switched on. Some setting options depend on the vehicle equipment.
Function buttons and symbols of the rear view camera system:

Yellow lines: vehicle path depending on the steering angle.
Yellow auxiliary boxes: front and rear limits of the parking space (mode 2).
Green lateral line: turning point when driving into a parking space (mode 2).
Using images from the camera to estimate the distance from obstacles (people, vehicles
etc.) is inaccurate and could cause accidents and severe injuries.
•Camera lenses enlarge and distort the field of vision and make objects appear different
and inaccurate on the screen.
WARNING
Red and green frames: vehicle outline (mode 2).
Trailer support (mode 3)
In vehicles with a factory-fitted towing bracket, the trailer support function can be used when
approaching a trailer drawbar. The powerful zoom level used in this mode means that obstacles
behind the vehicle appear very late.
Auxiliary lines are shown on the Infotainment system.
Red line: position of the towing bracket.
Green lines: distance to towing bracket. The distance intervals are around 0.1 m in each case.
Orange line: predicted path of the towing bracket, depending on the steering angle.
Crossing traffic (mode 4)
This display representation helps the driver to monitor traffic behind the vehicle and can be used in
situations such as driving out of a garage or narrow exits, for example.
