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.

Steering assistance during collision risks limitations
The function may have limited functionality in certain situations and not intervene, e.g.:
for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no sidelane markings
outside the speed range 60-140 km/h(37-87 mph)
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
Functionality may also be reduced in other sit-uations, such as: road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

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)

Park Assist Camera trajectory lines
*
The Park Assist Cameras use trajectory lines and fields on the screen to indicate the vehi-cle's position in relation to its immediate sur-roundings.
Example of trajectory lines.
The lines on the screen are projected as if they were painted lines on the ground behind thevehicle and are directly affected by the way inwhich the steering wheel is turned. This makes it possible for the driver to see path thevehicle will take, even if he/she turns thesteering wheel.
CAUTION

Bear in mind that when the rearward camera view is selected, the screenonly shows the area behind the vehicle– pay attention to the sides and frontof the vehicle when steering whilereversing.
The same applies to the reverse – payattention to what is happening withthe rear parts of the vehicle when thefront camera view is selected.
Note that the guide lines show theshortest
path – pay extra attention to
ensure that the vehicle sides do notcome in contact with/travel over any-thing when steering while driving for-ward or that the vehicle front movestoward/over anything when steeringwhile reversing.
