Rear Collision Warning*95  
Limitations of Rear Collision  
WARNING  
Warning*97  
The Rear Collision Warning96 (RCW) function  
can help the driver to avoid being hit by a  
vehicle approaching from behind.  
Drivers in vehicles behind can be warned  
about an imminent collision by the function  
flashing intensively with the direction indica-  
tors.  
The function is supplementary driver  
support intended to facilitate driving  
and make it safer – it cannot handle all  
situations in all traffic, weather and  
road conditions.  
In certain cases the Rear Collision Warning  
(RCW) may have difficulty helping the driver  
in the event of a collision risk.  
This can, for example, be if:  
the vehicle approaching from behind is  
detected too late  
The driver is advised to read all sec-  
tions in the Owner's Manual that relate  
to this function to learn about factors  
such as its limitations and what the  
driver should be aware of before using  
the system.  
If, at a speed below 30 km/h (20 mph), the  
function detects that the car is in danger of  
being hit from behind, the seatbelt tensioners  
may tension the front seatbelts. The Whiplash  
Protection System is also activated in the  
event of a collision.  
the vehicle approaching from behind  
changes lane at the last moment  
a trailer, bicycle rack or similar is con-  
nected to the car's electrical system - the  
function is then deactivated automatically.  
Driver support functions are not a sub-  
stitute for the driver's attention and  
judgement. The driver is always  
responsible for ensuring the car is  
driven in a safe manner, at the appro-  
priate speed, with an appropriate dis-  
tance to other vehicles, and in accord-  
ance with current traffic rules and reg-  
ulations.  
Immediately before a collision from behind,  
this function may also activate the foot brake  
in order to reduce the forward acceleration of  
the car during the collision. However, the foot  
brake is only activated if the car is stationary.  
The foot brake releases immediately if the  
accelerator pedal is depressed.  
NOTE  
In certain markets, RCW does not give a  
warning with the direction indicators due  
to local traffic regulations - in such cases,  
this part of the function is deactivated.  
This function is activated automatically each  
time the engine is started.

When BLIS detects a vehicle in Zone 1 or a  
quickly approaching vehicle in Zone 2, the  
indicator lamp on the door mirror on the affec-  
ted side illuminates with a constant glow. If  
the driver activates the direction indicator on  
the same side as the warning, the indicator  
lamp will change over from a constant glow to  
flashing with a more intense light.

Activating or deactivating BLIS  
WARNING  
The BLIS99 function can be activated or deac-  
tivated.  
The function is supplementary driver  
support intended to facilitate driving  
and make it safer – it cannot handle all  
situations in all traffic, weather and  
road conditions.  
If passing vehicles drive more than 15 km/h  
(9 mph) faster than the driver's vehicle, BLIS  
will not react.  
Activate or deactivate the  
function using this button in  
the centre display's function  
view.  
NOTE  
The driver is advised to read all sec-  
tions in the Owner's Manual that relate  
to this function to learn about factors  
such as its limitations and what the  
driver should be aware of before using  
the system.  
The lamp illuminates on the side of the car  
where the system has detected the vehicle.  
If the car is overtaken on both sides at the  
same time then both lamps illuminate.  
GREEN button indication – the function is  
activated.  
GREY button indication – the function is  
deactivated.  
Driver support functions are not a sub-  
stitute for the driver's attention and  
judgement. The driver is always  
responsible for ensuring the car is  
driven in a safe manner, at the appro-  
priate speed, with an appropriate dis-  
tance to other vehicles, and in accord-  
ance with current traffic rules and reg-  
ulations.  
If BLIS is activated when starting the engine,  
the function is confirmed by the door mirror  
indicator lamps blinking once.  
If BLIS was deactivated when the engine was  
switched off, it will continue to be deactivated  
when the engine is next started and no indica-  
tor lights will then be illuminated.
