WARNING
City Safety is supplementary driver sup- port, but it cannot detect all large animalsin all situations and, for example, cannotsee: partially obscured larger animals.
larger animals seen from the front or from behind.
running or fast moving larger animals.
larger animals if the contrast to the ani-mal's background is poor.
smaller animals such as cats and dogs.
Warnings and brake interventions may occur late or not at all. The driver is alwaysresponsible for ensuring that the vehicle isdriven correctly and with a safety distancesuitable for the speed.

Limitations of City Safety in crossing traffic
In certain situations, it may be difficult for
City Safety to help the driver avoid a collisionwith crossing traffic.
For example:
On slippery roads when Electronic Stabil- ity Control (ESC) is actively operating.
If an approaching vehicle is detected at alate stage.
If the oncoming vehicle is partiallyobstructed by another vehicle or object.
If the oncoming vehicle's headlights areoff.
If the oncoming vehicle is moving errati-cally and e.g. suddenly changes lanes at alate stage.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

City Safety helps provide assistance bystrengthening the driver's steering move-ments, but only if the driver has begun evasiveaction and the system detects that the driver'ssteering movements are not sufficient to avoida collision. The brake system is used simultaneously to further strengthen steering movements. The

Important warnings
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all. Never wait for a warning or assistance. Apply the brakes when necessary.
WARNING
Warnings and brake interventions can be triggered late or not at all if the traf-fic situation or external influences pre-vent the camera and radar unit fromproperly detecting pedestrians,cyclists, large animals or vehiclesahead of the vehicle.
To be able to detect vehicles at night,its front and rear lights must work andilluminate clearly.
The camera and radar unit have a lim-ited range for pedestrians and cyclists– the system can provide effectivewarnings and brake interventions if therelative speed is lower than 50 km/h(30 mph). For stationary or slow-mov-ing vehicles, warnings and brake inter-ventions are effective at vehicle speedsof up to 70 km/h (43 mph). Speedreduction for large animals is less than15 km/h (9 mph) and can be achievedat vehicle speeds over 70 km/h(43 mph). At lower speeds, the warn-ing and brake intervention for large ani-mals is less effective.
Warnings for stationary or slow-mov-ing vehicles and large animals can bedisengaged due to darkness or poorvisibility.
Warnings and brake interventions for pedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anythingon the inside or outside of the wind-shield, or in front of or around the cam-era and radar unit – this could disruptcamera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce thefunction, disengage it completely orgive an improper function response.

WARNING
The City Safety auto-brake function can prevent a collision or reduce colli-sion speed, but to ensure full brakeperformance the driver should alwaysdepress the brake pedal – even whenthe car auto-brakes.
The warning and steering assistanceare only activated if there is a high riskof collision – you must therefore neverwait for the collision warning or CitySafety to intervene.
Warnings and brake interventions forpedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
City Safety does not activate auto-braking intervention during heavyacceleration.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Steering assistance with braking
Intervention with steering assistance and braking
Braking intervention assists in situations where steering assistance alone is not suffi-cient. Braking force is automatically adaptedaccording to the situation at the moment thevehicle begins to run off the road. The function is active at speeds between 65-140 km/h (40-87 mph) on roads withclearly visible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side markerlines. If the vehicle is about to cross the edgeof the road, the function will attempt to steerthe vehicle back onto the road. If this is notsufficient to keep the vehicle on the road, thebrakes will also be applied. However, the function will not provide either
steering assistance or braking if the turn signal is used. The function will also not be activated if it detects that the driver is actively operatingthe vehicle.

Rear Collision Warning *85
The Rear Collision Warning 86
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
