Introduction
City Safety™1
is a support system designed
to help the driver avoid low speed collisions when driving in slow-moving, stop-and-gotraffic. City Safety™ is not active if your vehicle’s speed is below approximately 2 mph(4 km/h). This means that City Safety™ willnot react if your vehicle approaches anothervehicle at very low speed, for example, whenparking. The function is active at speeds up to approximately 30 mph (50 km/h) and assiststhe driver by applying the brakes automati-cally, thereby avoiding or helping to reducethe effects of a collision. City Safety™ is designed to intervene as late as possible to help avoid unnecessary activa-tion. City Safety™ triggers brief, forceful braking if a low-speed collision is imminent. However,the system will not intervene in situationswhere the driver actively steers the vehicle orapplies the brakes, even if a collision cannotbe avoided. This is done in order to alwaysgive the driver’s actions highest priority. City Safety™ activates in situations where thedriver has not applied the brakes in time,which means that the system cannot help thedriver in all situations. City Safety™ should not be used to alter the way in which the driver operates the vehicle.The driver should never rely solely on thissystem to safely stop the vehicle. Normally, the occupants of the vehicle will not be aware of City Safety™ except whenthe system intervenes when a low-speed col-lision is imminent. If the vehicle is also equipped with the optional Collision Warning with Full Auto-brake and Pedestrian Detection system, thetwo systems interact. For more informationabout the Collision Warning with Auto-brakesystem, see page 178.

Pedestrian and Cyclist Detection with Full Auto Brake*

178* Option/accessory, for more information, see Introduction.
Introduction
Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver ifthere is a risk of a collision with a pedestrian,a cyclist, a vehicle ahead that is at a standstillor one that is moving in the same direction asyour vehicle. This system consists of the following three functions: • Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake
efficiently in a critical situation.
• Auto-brake
brakes the vehicle automati-
cally if a collision with a pedestrian, a cyclist or another vehicle cannot be avoi-ded and the driver does not apply thebrakes in time or steer around the per-son/vehicle. Auto-brake can help preventa collision or reduce the speed at which acollision occurs.
Since Pedestrian and Cyclist Detection with Full Auto Brake is activated in circumstanceswhere the driver should have begun brakingmuch sooner, the system will not be able toassist the driver in all situations. This system is designed to activate as late as possible to help avoid unnecessary interven-tion. The system should not be used in such a waythat the driver changes his/her way of operat-ing the vehicle. If the driver relies entirely onthe system, the chances of an accident even-tually occurring increase considerably. The Pedestrian and Cyclist Detection with Full Auto Brake and City Safety™ systems sup-plement each other. See page 172 fordetailed information about City Safety™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations.For that reason, never test the Auto-brakesystem by driving toward a person orobject. This could result in serious injury ordeath.
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake does not work in alldriving, traffic, weather and road con-ditions. It does not react to vehiclesnot traveling in the same direction asyour vehicle.
• Pedestrian and Cyclist Detection withFull Auto Brake does not react to ani-mals.
• Warnings are only provided when therisk of collision is high. The "Function"section provides information aboutlimitations that the driver must beaware of before using Collision Warn-ing.
• Pedestrian and Cyclist Detection withFull Auto Brake will not provide awarning or brake the vehicle forpedestrians or cyclists at speedsabove 50 mph (80 km/h).

Cyclist detection
Optimal example of what the system considers to be a cyclist: clear body/bike contours, straightfrom behind and directly in front of the vehicle
In order to help detect a cyclist, the system has to receive clear information about thecontours of the cyclist's body and the bike. Ithas to able to clearly detect the bike, thecyclist's head, arms, shoulders, legs andupper and lower body combined with the per-son's pattern of movement when cycling.
The function only detects cyclists from behind who are moving in the same direction as yourvehicle
The Cyclist Detection feature requires the fol- lowing in order to function: • The cyclist must be an adult riding an "adult-size" bike
• The bike must be equipped with anapproved and clearly visible rear-facingred reflector that is mounted at least27 in. (70 cm) above the road surface
• The feature can only detect a cycliststraight from behind and who is moving inthe same direction as your vehicle
• A cyclist who is to the left or right of yourvehicle may be detected late or not at all. •
The camera's capacity to see a cyclist atdawn or dusk is limited, much as it is forthe human eye.
• The camera's function is deactivated andwill not detect a cyclist in darkness or intunnels, even if there is street lighting inthe area.
• For optimal cyclist detection, CitySafety™ must be activated (seepage 172)
