Limitations for
assistance at risk of
collision
Assistance at risk of collision
102
has certain limi-
tations that a driver needs to know about.
Limitations of brake assistance
Extra equipment
Low-hanging objects, e.g. a flag/pennant for
projecting load, or accessories such as auxiliary
lamps and bull bars that are higher than the
car's bonnet, limit the function as they may
obstruct the camera or radar unit.
Skidding
On slippery road surfaces the braking distance
is extended, which may reduce the capacity of
the function to avoid a collision. In such situa-
tions, the anti-lock brakes and the stability con-
trol ESC
103
are designed to give the best possi-
ble braking force with maintained stability.
Low speed
The function is not activated at very low speeds
- below 4 km/h (3 mph) - and the system there-
fore does not intervene in situations where your
car is approaching a vehicle ahead very slowly,
e.g. when parking.
Active driver
The driver's commands are always prioritised. In
situations where the driver is steering and
accelerating in a decisive manner, the function
does not intervene, even if a collision is unavoid-
able. Active and aware driving behaviour can
therefore delay a collision warning and interven-
tion in order to minimise unnecessary warnings.
Limitations of steering assistance
In certain situations the function may have lim-
ited functionality and fail to intervene in the fol-
lowing cases, for example:
• for small vehicles, such as motorcycles
• if the majority of the car has steered into the
adjacent lane
• on roads/in lanes with unclear or non-existent
lane markings
• outside the speed range 60-140 km/h
(37-87 mph)
• as the steering servo for speed-dependent
steering wheel resistance is working at
reduced power – e.g. when cooling due to
overheating.
Other demanding situations can include:
• road works
• winter road conditions
• narrow roads
• poor road surface
• a very “sporty” driving style
• poor weather with reduced visibility.
In these demanding situations the function may
have difficulty in helping the driver in the right
way.
