Road Sign Information (RSI)*
RSI is a feature that helps the driver see roadsigns showing the posted speed limit.
Examples of readable road signs
If the vehicle passes a sign showing the speedlimit, this will be displayed in the instrument paneland the head-up display*.

NOTE
If the vehicle is equipped with the SensusNavigation system, speed-related informationis provided by this system in the followinginstances:
•In cases where the speed limit is givenindirectly (e.g., when driving on highwaysor other major roads).
•If a previously read speed limit sign is nolonger considered valid and no new signhas been passed.
If a third-party navigation system is beingused, RSI has no support for speed-relatedinformation.

WARNING
RSI does not function in all situations and isonly intended to provide supplementary infor-mation.
The driver is always responsible for operatingthe vehicle safely.

Driving lane assistance provide vibrations in the steeringwheel8.
Depending on the settings used, Lane KeepingAid functions in different ways:
•Assistance type Steering9 is activated: whenthe vehicle approaches a traffic lane markerline, LKA will provide active steering assis-tance to help steer it back into the lane.
•Assistance type Warning9 is activated: if thevehicle is moving out of its traffic lane, anaudible signal and/or vibrations in the steer-ing wheel will be provided.

NOTE
If the turn signal is used, Lane Keeping Aidwill not provide an alert or steering assis-tance.

WARNING
Lane Keeping Aid is only intended to assistthe driver and does not function in all driving,weather, traffic or road conditions.
As the driver, you have full responsibility foroperating the vehicle in a safe manner.

Steering assistance
In order for LKA's steering assistance to function,the driver's hands must be on the steering wheel,which the system monitors continuously.
If the driver's hands are not onthe steering wheel, this symbolwill illuminate in the instrumentpanel and the following mes-sage will be displayed:
•Lane Keeping Aid – Apply steering
If the driver does not begin to steer the vehicle,the symbol will illuminate again, an audible signal
will sound and the following message will be dis-played:
•Lane Keeping Aid – Standby untilsteering applied
If the driver still does not begin to steer the vehi-cle, LKA will go into standby mode. The functionwill not become available again until the driveractively steers the vehicle
Lane assistance do not react
The traffic lane assistance system do not intervene insharp curves
In certain cases, such as during active driving or ifthe turn signal is used, the traffic lane system willnot react if the vehicle crosses a lane markerline.
8The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:9See "Type of assistance" in the article "Activating/deactivating Lane Keeping Aid".

The setting selected when the engine wasswitched off will be used the next time theengine is started.

Limitations
In certain situations, it may be difficult for Run-offMitigation to assist the driver. In such cases, it isadvisable to deactivate the function.
Examples of these situations include:
•road construction
•winter driving conditions
•poor road surfaces
•narrow roads
•a very active driving style
•bad weather with reduced visibility
•edges or lines other than the lane's markerlines
•roads with indistinct or no lane marker lines
The Run-off Mitigation function use the vehicle'scamera, which has general limitations. See thearticle "Camera limitations".
WARNING
•Run-off Mitigation is only intended toassist the driver and does not function inall driving, weather, traffic or road condi-tions.
•This function cannot detect barriers, railsor similar obstructions at the side of aroad or traffic lane.
•As the driver, you have full responsibilityfor operating the vehicle in a safe man-ner.

Park Assist limitations
The Park Assist system has certain limitations.

NOTE
A trailer hitch whose wiring is integrated withthe vehicle's electrical system will be takeninto account when measuring the availablespace behind the vehicle.
NOTE
•The system will not detect high objects,such as a loading dock, etc.
•Certain materials or fabrics may not bedetected by the sensors. Objects made ofthese materials or people wearing cloth-ing made of these fabrics may not bedetected.
•Children or animals near the vehicle maynot always be detected.
•Objects such as chains, thin shiny polesor low objects may temporarily not bedetected by the system. This may resultin the pulsing tone unexpectedly stoppinginstead of changing to a constant tone asthe vehicle approaches the object. Insuch cases, use caution when backing upor stop the vehicle to help avoid damage.
•In certain circumstances, the park assistsystem may give unexpected warning sig-nals that can be caused by externalsound sources that use the same ultra-sound frequencies as the system. Thismay include such things as the horns ofother vehicles, wet tires on asphalt, pneu-matic brakes, motorcycle exhaust pipes,other vehicles with similar ultrasound sys-tems, etc. This does not indicate a fault inthe system.
Cleaning the sensors
Location of the Park Assist sensors
The sensors must be cleaned regularly to ensurethat they work properly. Clean them with waterand a suitable car washing detergent.

NOTE
If the sensors are obstructed by e.g., dirt,snow, or ice, this could result in false warningsignals from the park assist system or thesystem may not function at all.

Park Assist Pilot (PAP)*
Park Assist Pilot (PAP) helps the driver drive intoparallel or perpendicular parking spaces andleave parallel parking spaces.
Park Assist Pilot provides assistance when park-ing by measuring the parking space and turningthe steering wheel to guide the vehicle into thespace.
Information about the actions required by thedriver is provided in the center display in the formof symbols, images and text.

NOTE
While PAP is active, the driver's task is to:
•carefully monitor the area around thevehicle
•follow the instructions provided in thecenter display
•select a gear (D or R) when prompted
•regulate the vehicle's speed
•apply the brakes when necessary andstop the vehicle
Types of parking
Parallel parking
Procedure for parallel parking
PAP helps park the vehicle as follows:
1.The system searches for and measures apossible parking space. While this is beingdone, the vehicle's speed may not exceedapprox. 20 mph ( 30 km/h). When backinginto a space, the speed may not exceedapprox. 4 mph ( 7 km/h).
2. The vehicle is steered while it is backing intothe parking space. The driver controls thevehicle's speed.
3. The vehicle's position in the parking space isadjusted by prompting the driver to move for-ward and rearward while the system steers.
Perpendicular parking
Procedure for perpendicular parking
PAP helps park the vehicle as follows:
1.The system searches for and measures apossible parking space. While this is beingdone, the vehicle's speed may not exceedapprox. 4 mph ( 7 km/h).
2. The vehicle is steered while it is backing intothe parking space and its position in thespace is adjusted by prompting the driver toselect D or R while the system steers. Thedriver has to control the vehicle's speed.

NOTE
PAP's Park out function cannot be used tohelp a vehicle leave a parking space if thePerpendicular parking function was usedto park the vehicle.

Parking
Procedure for parking:
1. The system searches for and measures apossible parking space.
2. The vehicle is steered while it is backing intothe parking space.
3. The vehicle's position is adjusted in the park-ing space by moving forward and rearward.
