In a diagonal parking space, CTA may be completely "blind" on one side of your vehicle.
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out of a parking space, CTA's field of vision changes in relation to the obstructing vehicle/object and its blind zone is reduced.
Examples of further limitations

The
auto brake sub-function only detects
vehicles in motion and may therefore not
"see" and brake for e.g. stationary obsta- cles, a cyclists or a pedestrian.
Dirt, ice and snow covering the sensorsmay reduce functionality and prevent thesystem from providing warnings.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.: in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Lane Keeping Aid
Lane Keeping Aid (LKA 85
) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.
Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
A camera monitors the road/traffic lane's marker lines.
Lane Keeping Aid steers the vehicle back into its lane.

Lane Keeping Aid limitations
In certain demanding driving conditions, Lane Keeping Aid (LKA 88
) may not be able to prop-
erly assist the driver. In these situations, it is recommended that the function be deacti-vated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's side markings
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
The function cannot detect barriers, railings orsimilar obstacles at the side of the lane.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.
