Rear Collision Warning *59
The Rear Collision Warning 60
(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.

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
NOTE
In certain markets RCW does
not warn
with the direction indicators due to local traffic regulations – in such cases, that partof the function is deactivated.
NOTE
The warning with direction indicators for Rear Collision Warning * is deactivated if
the collision warning distance in the City Safety function is set to the lowest level "

BLIS
*
The BLIS 62
function is designed to help pro-
vide assistance in heavy traffic with several lanes moving in the same direction by helpingthe driver to detect the presence of vehiclesin the "blind spot" area behind and to the sideof the vehicle.
Location of BLIS indicator light.
BLIS is a driver support system designed to alert the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacentlanes.
BLIS overview
Blind spot zone
Rapidly approaching vehicle zone.
The system is designed to react to:
vehicles passing your vehicle
vehicles that are rapidly approaching your vehicle from behind.
When BLIS detects a vehicle in zone 1 or arapidly approaching vehicle in zone 2, an indi-cator light will illuminate in the relevant rear-view mirror and glow steadily. If the driverthen uses the turn signal on the side in whichthe warning has been given, the indicator lightwill become brighter and begin flashing. BLIS is active when your vehicle is traveling at a speed over 10 km/h (6 mph).

Cross Traffic Alert *67
Cross Traffic Alert(CTA) is a supplementary driver support system to BLIS 68
that is
intended to help the driver detect vehicles crossing behind the vehicle while backing up. The auto-brake subfunction can help the
driver stop the car if there is a risk of collision with an unobserved vehicle.
Examples of areas in which CTA can help the driver detect obstacles while backing up.
CTA supplements BLIS by detecting traffic crossing from the side, e.g. when backing outof a parking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedes-trians or smaller objects such as bicycles. CTA is only active when the vehicle is movingbackward or if reverse gear is engaged. If CTA detects that something is approaching your vehicle from the side:
an audible signal will sound from eitherthe left or right speaker, depending onwhich side of your vehicle the object isapproaching from.
an icon will illuminate in the
Park Assist
System graphic on the screen.
an icon will appear in the Park Assist Cam- era's Top view.
Illuminated CTA icon in the
Park Assist System
graphic on the screen.
If the driver does not pay attention to the warning from CTA and a collision is unavoida- ble, the
auto brake function will intervene to
stop the vehicle and a text will be shown onthe instrument panel to explain why the vehi-cle was braked.

limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in
certain situations. Auto-brake is active atspeeds under 15 km/h (9.3 mph).
WARNING
The auto-brake sub-function can only
detect and apply the brakes for other mov- ing vehicles – not for e.g. stationary obsta-
cles, cyclists or pedestrians.
CTA has certain limitations – The CTA sen- sors, for example, cannot "see" through otherparked vehicles or objects blocking the vehi-cle. Below are a few examples of situations in which CTA's field of vision may be initially lim-ited and approaching vehicles may thereforenot be detected until they are very close toyour vehicle:

70 Warning for crossing traffic when the vehicle is backing up.
