limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in
certain situations. Auto-brake is active atspeeds under 15 km/h (9.3 mph).
WARNING
The auto-brake sub-function can only
detect and apply the brakes for other mov- ing vehicles – not for e.g. stationary obsta-
cles, cyclists or pedestrians.
CTA has certain limitations – The CTA sen- sors, for example, cannot "see" through otherparked vehicles or objects blocking the vehi-cle. Below are a few examples of situations in which CTA's field of vision may be initially lim-ited and approaching vehicles may thereforenot be detected until they are very close toyour vehicle:
69 Warning for crossing traffic when the vehicle is backing up.
70 Warning for crossing traffic when the vehicle is backing up.

Road Sign Information (RSI 75
) displays road
signs in different ways depending on the sign and situation.
Example 76
of registered speed information.
When the function has registered a speed limit sign, the sign will be displayed as a sym-bol in the instrument panel and a coloredmarking will be shown in the speedometer'sspeed scale. If the vehicle is equipped with Sensus Navigation *, speed-related information will
also be retrieved from map data, which means that the instrument panel can display orchange information about speed limits even if the vehicle has not passed a speed-relatedsign.
Signs for "School" and "Children playing"
If the warning sign

"School" or "Children play- ing" is included in the satel- lite navigator's map data 77
, a

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.

approaches a lane marker line, the func- tion will actively steer the vehicle back intothe lane using light pressure on the steer-ing wheel.

Warning enabled: If the vehicle is about
to move over a lane marker line, the driver will be alerted by vibrations in the steeringwheel.
There is also an option for activating steeringassistance and alerts at the same time.
NOTE
When the direction indicators/turn signals are activated, the Lane Keeping Aid doesnot provide any warning or intervene withsteering.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle.
Side sensors
The warning signal will begin pulsating rapidly when the obstacle is less than approx. 25 cm (0.8 ft) fromthe vehicle.
Park Assist's side sensors are automatically activated when the engine is started. They areactive at speeds below 10 km/h (6 mph). The distance monitored is approx. 25 cm (0.8 ft) out from the sides. The detection area of the side sensors increa- ses significantly, however, when the steering angle of the front wheel increases and depending on the position of the steeringwheel, obstacles up to approx. 90 cm (3 ft)
