Run-off Mitigation
The function of Run-off Mitigation is to assist the driver to reduce the risk of the car accidentallyleaving the road by means of actively steeringthe car back onto the road.
The function is active within the speed range 65-140 km/h (40-87 mph) on roads with clearlyvisible side markings/lane lines. A camera scans the edges of the road and the painted side markings. If the car is about to crossthe edge of the road, Run-off Mitigation willactively steer the car back onto the road. In addi-tion, if steering intervention is considered insuffi-cient to avoid run-off, brake intervention may alsobe activated. Run-off Mitigation does not intervene with either steering assistance or brake intervention if thedirection indicators are used. If the functiondetects that the driver is driving the car in anactive way, activation of Run-off Mitigation will besuppressed for a short time. The function has two activation levels: • Steering assistance only
• Steering assistance with brake intervention
Run-off Mitigation with steering assistance
Run-off Mitigation intervenes with steering assistance.
Run-off Mitigation with steering assistance
and brake intervention
Run-off Mitigation intervenes with steering assistance and braking.
Brake intervention helps in situations where steering assistance alone is not sufficient. Thebrake force is adapted automatically dependingon the situation at the time of run-off.
Settings for Run-off MitigationThe Run-off Mitigation function is selectable -the driver can select On or Off by dragging downthe centre display's top view and there searchingfor the following:
SettingsMy CarIntelliSafeLane
Assistance
To activate Run-off Mitigation:
• Select the box at
Collision Avoidance
Assistance, Steering aid during
increased collision risk - the function is
then activated.
The current setting for Run-off Mitigation when the engine is switched off remains the next timethe engine is started.
Limitations of Run-off MitigationIn certain demanding conditions, Run-off Mitiga-tion may have difficulty helping the driver cor-rectly. In such cases, it is recommended that thefunction be switched off. Examples of such conditions are:
• road works
• winter road conditions

Along the sides
Parking assistance side sensors are activated automatically when the engine is started. Theyare active at speeds below 10 km/h (6 mph). The measuring range starts approx. 30 cm from the sides. The acoustic signal for obstacles onthe sides comes from the side loudspeakers.
Forwards
NOTE: The illustration is schematic - details may vary depending on car model.
The front parking assistance sensors are acti- vated automatically when the engine is started.The front sensors are active at speedsbelow 10 km/h (6 mph). The measuring range starts approx. 0.8 metres in front of the car.
NOTE
Parking assistance is deactivated when the parking brake is applied or P mode is
selected in a car with an automatic gearbox.
IMPORTANT
When auxiliary lamps are fitted: Remember that these must not obscure the sensors - theauxiliary lamps may then be perceived as anobstacle.

Limitations of Parking assistance *
The Parking assistance function may have limita- tions in certain situations.
NOTE
Since a towbar is configured with the car's electrical system, towbar protrusion isincluded when the function measures the dis-tance to an object behind the car.
IMPORTANT
Objects e.g. chains, thin glossy poles or low barriers may be in the "signal shadow" andare then temporarily not detected by the sen-sors - the pulsating tone may then unexpect-edly stop instead of changing over to theexpected constant tone. The sensors cannot detect high objects, such as projecting loading docks.
• In such situations, pay extra attention andmanoeuvre/reposition the car particularlyslowly or stop the current parkingmanoeuvre - there may be a high risk ofdamage to vehicles or other objects sinceinformation from the sensors is notalways reliable in such situations.
IMPORTANT
In certain conditions the parking assistance system may produce incorrect warning sig-nals that are caused by external soundsources that emit the same ultrasonic fre-quencies that the system works with. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles, etc.
Maintenance
Location of the parking sensors 24
.
For parking assistance to work optimally, the parking assistance sensors must be cleaned reg-ularly with water and car shampoo.

Parking with Active parking assistance *
The Active parking assistance (Park Assist Pilot - PAP) helps the driver park in three steps. Thefunction can also help the driver to leave a park-ing space.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.
PAP can be activated if the following criteria are met once the engine has been started:
• No trailer is attached to the car.
• Speed must be lower than 30 km/h(20 mph).
NOTE
The distance between the car and parking spaces should be 0.5-1.5 metres while PAPis searching for a parking space.
ParkingThe PAP function parks the car using the follow- ing steps:
1. A parking space is identified and measured.
2. The car is reversed into the space.
3. The car is positioned into the space - the
system may then request that the driver changes gear.
Finding and measuring parking spaces
The function can be activated in the centre display's functionview. It can also be accessed from the camera views.
Principle for parallel parking.
Principle for perpendicular parking.
1. Drive no faster than 30 km/h (20 mph) forparallel parking or 20 km/h (12 mph) for perpendicular parking.
2. Tap on the
Park In button in function view.
> PAP searches for a parking space and checks whether it is big enough.
3. Keep an eye on the centre display - be ready to stop the car when the graphic and mes- sage indicate that a suitable parking spacehas been found.
> A pop-up window is shown.
4. Select
Parallel parking or Perpendicular
parking and select reverse gear.
