Rear Collision Warning
The Rear Collision Warning (RCW) function can help the driver to avoid being hit by a vehicleapproaching from behind.
RCW is activated automatically each time the engine is started. The RCW can warn the driver in a vehicle approaching from behind that a collision is immi-nent by rapidly flashing the direction indicators. If, at a vehicle speed below 30 km/h (20 mph), the RCW function detects that the car is in dan-ger of being hit from behind, the seatbelt ten-sioners may tension the front seatbelts and theWhiplash Protection System safety system isactivated. Immediately before the collision, RCW may also activate the foot brake in order to reduce the for-ward acceleration of the car during the collision.However, the foot brake is only activated if thecar is stationary. The foot brake releases immedi-ately if the accelerator pedal is depressed.
LimitationsIn certain cases the RCW may have difficultyhelping the driver in the event of a collision risk.This can be for example:
• if the vehicle approaching from the rear isdetected too late
• if the vehicle approaching from the rearchanges lane at the last moment •
if the vehicle approaching from the rear has aspeed exceeding 80 km/h (50 mph).
NOTE
In certain markets, RCW does
not give a
warning with the direction indicators due to local traffic regulations - in such cases, thispart of the function is deactivated.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the warn-ing distance for collision warning in the CitySafety function is set at the lowest level "
Late".
The seat belt pre-tensioning and braking functions are, however, still active.

Blind Spot Information
*
The Blind Spot Information (BLIS) function is designed to give a warning of vehicles diago-nally behind and to the side of your car so as togive assistance in heavy traffic on roads withseveral lanes in the same direction.
BLIS is a driver aid intended to give a warning of: • vehicles in the car's blind spot
• quickly approaching vehicles in the left and right lanes closest to the car.

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.

Activating/deactivating Parking assistance*
The Parking assistance function can be acti- vated/deactivated.
The front and side parking assistance sensors are activated automatically when the engine isstarted. The rear sensors activate if the car rollsbackwards or if reverse gear in engaged.
The function is activated/deac-tivated in function view in thecentre display. Parking assistance can also be activated/deactivated from thecamera views.
–Tap on the Park Assist button in function
view.
> Parking assistance is activated/deacti- vated, a green/grey indicator is displayed in the button.

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.

Park Assist Pilot *
Active parking assistance (Park Assist Pilot - PAP) helps the driver to park in or leave a park-ing space.
PAP checks first if a space is sufficiently big and thereafter helps the driver to turn the steeringwheel and manoeuvre the car into the space. The centre display indicates with symbols, graph- ics and text the various operations to be carriedout and when to do so.
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.

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.

Limitations of Park Assist Pilot *
The Active parking assistance (Park Assist Pilot – PAP) function may have limitations in certainsituations.
Parking is discontinuedA parking sequence will be discontinued:
• if the driver moves the steering wheel
• if the car is driven too quickly - above 7 km/h (4 mph)
• if the driver presses
Cancel in the centre
display
• when the anti-lock brakes or the Electronic stability control are engaged - e.g. when awheel loses grip on a slippery road.
Where applicable, a message in the centre dis-play states the reason for a parking sequencebeing discontinued.
NOTE
Dirt, ice and snow covering the sensors will reduce their function and may prevent meas-urement.
IMPORTANT
Under certain circumstances, PAP is unable to find parking spaces - one reason for thismay be the fact that there is interference withthe sensors from external sound sourceswhich emit the same ultrasound frequenciesas those with which the system works. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles etc.
Driver responsibilityThe driver should bear in mind that the PAP is an aid – not an infallible, fully-automatic function.The driver must therefore be prepared to inter-rupt a parking step. There are also a few details to bear in mind while parking, e.g.:
• PAP bases itself on the locations of vehiclesalready parked nearby - if they are inap-propriately parked, your own car's tyres andwheel rims may be damaged by contact withthe kerb.
• PAP is designed for parking on straightstreets - not sharp curves or bends. For thisreason, make sure the car is parallel to theparking space when PAP measures thespace. •
Parking spaces on narrow streets are notalways feasible, since the space required formanoeuvring may not be sufficient.
• Bear in mind that the front of the car mayswing out towards oncoming traffic whilebeing parked.
• Objects situated higher than the detectionareas of the sensors are not taken intoaccount when calculating the parkingmanoeuvre. This may cause PAP to turn intothe parking space too early, and hence suchparking spaces should be avoided.
• The driver is responsible for determiningwhether the space selected by PAP is suita-ble for parking.
• Use approved tyres 28
with the correct tyre
pressure - this affects the ability of PAP topark the car.
• Heavy rain or snow may cause the system tomeasure the parking space incorrectly.
• Do not use PAP if snow chains or a sparewheel are fitted.
• Do not use PAP if cargo items are protrudingfrom the car.
• Perpendicular parking spaces may be missedor offered unnecessarily if one parked car isprotruding more than other parked cars.

"Approved tyres" refers to tyres of the same type and make as those fitted new on delivery from the factory.
