3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, the automaticbraking function will be triggered. This occurswhether or not the driver is pressing the brakepedal. Full braking force will be applied to reducethe speed at impact or reduced braking effect willbe applied if this is sufficient to avoid the colli-sion. The seat belt tensioners may be activated along with the automatic braking function. See "Seatbelt tensioners" for more information. In certain situations, auto-braking may begin with a limited braking force before applying full brak- ing force. If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with a slower-moving vehicle ahead, yourspeed will be reduced to that vehicle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text mes- sage will appear in the instrument panel to notifythe driver that the function is/was activated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. The drivermust not only rely on City Safety to brake thevehicle.

Setting a warning distance for CitySafety
City Safety is always active, but the function's warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically each timethe engine/electric motor is started.
The alert distance determines the sensitivity of the system and regulates the distance at whichthe light, sound and brake pulsations will be acti-vated. To select warning distance:
1. Select
SettingsMy CarIntelliSafe in
the center display's Top view.
2. Under
City Safety Warning, tap Late,Normal or Early to set the desired warning
distance.
If the driver feels that the
Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead. If the driver feels that the warnings are too fre- quent and distracting, the warning distance canbe reduced. This will reduce the total number ofwarnings, but it will also result in City Safety pro-viding warnings at a later stage.

Rear Collision Warning
The Rear Collision Warning (RCW) function can help the driver avoid rear-end collisions fromvehicles approaching from behind.
RCW is automatically activated each time the engine is started. RCW can warn the driver of a potential collision with vehicles approaching from behind by rapidlyflashing the turn signals. If, at a speed below 30 km/h (20 mph), the RCW function detects that the car is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seatbelts and activate the WhiplashProtection System safety system. Immediately before a collision from behind, RCW may also activate the foot brake in order toreduce the forward acceleration of the car duringthe collision. However, the brakes will only beapplied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Rear Collision Warning limitations
In some situations, it may be difficult for RCW to warn the driver of a collision risk.
This may be the case if:
• the vehicle approaching from the rear is detected at a late stage
• the vehicle approaching from the rearchanges lanes at a late stage
• the vehicle approaching from the rear is mov-ing at a speed above 80 km/h (50 mph)
• a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - theRCW function will then be automaticallydeactivated.
NOTE
In certain markets RCW does
not warn with
the direction indicators due to local traffic regulations – in such cases, that part of thefunction is deactivated.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the colli-sion warning distance in the City Safety func- tion is set to the lowest level "
Late".
The seat belt tensioning and braking func- tions remain active.

Cross Traffic Alert limitations
CTA 87
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations and has certain limitations. The CTA sensors, forexample, cannot "see" through other parkedvehicles or objects blocking the vehicle. Below are a few examples of situations in which CTA's field of vision may be initially limited andapproaching vehicles may therefore not bedetected until they are very close to your vehicle:
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely "blind" on one side of your vehicle.
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out of a parking space, CTA's field of vision changes inrelation to the obstructing vehicle/object and itsblind zone is reduced.
