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*
The Park Assist function can help the driver when maneuvering in tight spaces by indicat-ing distances to obstacles using audible sig-nals and graphics in the center display.
Display view showing obstacle zones and sensor sectors.
The center display shows an overview of the vehicle in relation to objects that have beendetected. The marked sector indicates where the obsta- cle is located. The closer the vehicle symbol isto a marked sector forward/rearward, thecloser the detected obstacle is to your vehicle. The side sectors change color as the distance between the vehicle and an object decreases. The audible signals will also speed up the closer the obstacle is to the vehicle. The vol- ume of the audio system will be automaticallylowered. Audible signals for obstacles in front and to the sides of the vehicle are active when thevehicle is moving but will cease after the vehi-cle has been stationary for approx. 2 seconds.Audible signals for obstacles behind the vehi-cle will remain active even when the vehicle isstationary. If a detected obstacle is within approx. 30 cm (1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in. At distances within approx. 25 cm (0.8 ft) from an obstacle to the sides of the vehicle, anrapid pulsing signal will be given and theactive sector fields will change color fromORANGE to RED. The volume of the Park Assist audible signals can be adjusted while the signal is being givenusing the
>II knob or in the center display's
Top view under
Settings.
NOTE
Besides in the sector closest to the vehicle symbol, audible warnings are only providedfor objects located directly in the vehicle'spath.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

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 limitations (p. 359)
Park Assist limitations Park Assist may not be able to detect all con- ditions in all situations and functionality maytherefore be limited in certain cases.
The driver should be aware of the following limitations for Park Assist:
WARNING
The parking sensors have dead/blind spots where objects cannot bedetected.
Pay particular attention to people andanimals near the vehicle.
Bear in mind that the front end of thevehicle may swing out towards oncom-ing traffic during the parking maneuver.

CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the"signal shadow" and then go temporarilyundetected by the sensors – the pulsatingtone may then unexpectedly stop insteadof becoming a constant tone as expected. The sensors cannot detect high objects, such as protruding ramps. In such situations, pay extra attention and maneuver/drive the vehicle veryslowly or stop the current parkingmaneuver – there may be a high risk ofdamage to the vehicle or other objectssince information from the sensors isnot always reliable in such situations.
CAUTION
In some circumstances, the Park Assist System may produce false warnings due toexternal sound sources with the sameultrasonic frequencies as those the systemworks with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.
