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 *
CTA 82
is a supplementary driver support system
to BLIS 83
that is intended to help the driver
detect vehicles crossing behind the vehicle while backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross- ing from the side, e.g. when backing out of aparking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedestrians orsmaller objects such as bicycles. CTA is only active when the vehicle is moving backward or if reverse gear is engaged. If CTA detects that something is approachingyour vehicle from the side:
• an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
• an icon will illuminate in the PAS 84
graphic
on the screen.
• an icon will appear in the Park Assist Cam-era's Top view.
