The function of the Lane Keeping Aid (LKA87  
)
In some situations, automatic braking ceases  
on coming to a standstill and the function is  
set in standby mode. This means that the  
brakes are released and the car may start to  
roll - the driver must therefore intervene and  
brake the car himself/herself to keep it station-  
ary.  
Driving support systems (p. 266)  
Adaptive cruise control* (p. 303)  
Pilot Assist* (p. 312)  
is to help the driver to reduce the risk of the  
car accidentally leaving its own lane on  
motorways and similar major routes.  
Lane Keeping Aid steers the car back into its  
lane and/or alerts the driver with vibrations in  
the steering wheel.  
Brake functions (p. 401)  
This may take place in any of the following sit-  
uations:  
Lane Keeping Aid is active within the speed  
range 65–200 km/h (40–125 mph) on roads  
with clearly visible side lines.  
The driver puts his/her foot on the brake  
pedal.  
On narrow roads the function may be unavail-  
able, in which case it goes into standby mode.  
The function becomes available again when  
the road is wide enough.  
The parking brake is applied.  
The gear selector is moved to P, N, or R  
position.  
The driver sets the adaptive cruise control  
or Pilot Assist to standby mode.  
Automatic activation of parking brake  
The Parking brake is applied if the function is  
holding the car stationary with the foot brake  
and:  
The driver opens the door or takes off  
his/her seatbelt.  
The function has kept the car stationary  
for more than approx. 10 minutes.  
The brakes have overheated.  
A camera reads the side lines of the road/lane.  
The driver switches the engine off.

WARNING  
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.  
Warning activated: If the car is about to  
cross a lane line, the driver is warned by  
means of vibrations in the steering wheel.  
There is also an option where both steering  
assistance and warning are activated simulta-  
neously.  
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.

switched on, there are no steering correc-  
tions or alerts from lane assistance.  
Lane assistance steers the car back into its lane.  
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.  
Lane assistance warns with steering wheel vibra-  
tions.  
Depending on settings, lane assistance acts in  
accordance with the following:

Hands on the steering wheel  
For steering assistance with lane assistance to  
work, the driver must have his/her hands on  
the steering wheel, which the system will con-  
tinue to monitor.  
If the driver does not keep  
his/her hands on the steering  
wheel, a warning signal is  
heard and a message encour-  
ages the driver to steer the  
car actively:

The function is supplementary driver  
support intended to facilitate driving  
and make it safer it cannot handle all

The function Collision avoidance assistance  
can help the driver reduce the risk of the car  
leaving its lane unintentionally and/or collid-  
ing with another vehicle or obstacle by  
actively steering the car back into its lane  
and/or swerving.  
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 function consists of these subfunctions:  
Steering assistance upon risk of run-off  
Steering assistance upon risk of head-on  
collision

Steering assistance upon risk of  
head-on collision  
Steering assistance has a number of subfunc-  
tions. Steering assistance upon risk of head-  
on collision can help a distracted driver who  
does not notice that the car is heading into  
the opposite lane.  
Related information  
Intervention with steering assistance and braking  
Brake intervention helps in situations where  
steering assistance alone is not sufficient. The  
brake force is adapted automatically depend-  
ing on the situation at the time of road run-off.  
The function is active within the speed range  
65-140 km/h (40-87 mph) on roads with  
clearly visible lane markings/lines.  
The function can assist by guiding the car back to its  
own lane.  
Oncoming vehicles  
Your car  
A camera scans the edges of the road and the  
painted side markings. If the car is about to  
leave the side of the road, the car is steered  
back onto the road and if the steering inter-  
vention is not enough to avoid run-off, the  
brakes are also activated.  
At the same time as steering intervention is  
activated, collision warning for driver support  
is also activated. However, the brake pulse  
included in the collision warning will not be  
activated.  
However, the function does not intervene with  
either steering assistance or brake interven-  
tion if the direction indicators are used. And if  
the function detects that the driver is actively

lane.  
Steering assistance upon risk of  
rear-end collision*  
Steering assistance has a number of subfunc-  
tions. Steering assistance if there is a risk of  
rear-end collision can help a distracted driver  
who does not notice that the car is about to  
leave its own lane while an oncoming vehicle  
is approaching at the same time, either from  
behind or in the blind spot.  
The function can even assist if the driver inten-  
tionally changes lanes using direction indica-  
tors without noticing that another vehicle is  
approaching.  
If the car is about to leave its own lane while  
an oncoming vehicle is approaching at the  
same time, the function can help the driver to  
steer the car back into its own lane.  
The function is active within the speed range  
60-140 km/h (37-87 mph) on roads with  
clearly visible lane markings/lines.  
However, the function does not intervene with  
steering assistance if the direction indicator is  
used. And if the function detects that the  
driver is actively driving the car, activation of  
the function will be delayed.  
The lamps in the door mirrors flash during  
steering intervention, regardless of whether  
the BLIS94 function is activated.

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.  
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.
