Blind Spot Information (BLIS) *
Blind Spot Information is a system designed to alert the driver to the presence of other vehiclesmoving in the same direction as your vehicle onroads with several lanes.
Blind Spot Information is a driving aid intended to:
• detect other vehicles in your door mirrors'"blind area"
• detect vehicles that are about to pass yourvehicle or are approaching your vehiclequickly from behind in the left and/or rightlanes
WARNING
•
Blind Spot Information is an information system, NOT a warning or safety systemand does not function in all situations.
• Blind Spot Information does not eliminatethe need for you to visually confirm theconditions around you, and the need foryou to turn your head and shoulders tomake sure that you can safely changelanes or back up.
• As the driver, you have full responsibilityfor changing lanes/backing up in a safemanner.
Overview
Blind Spot Information indicators
Indicator light
BLIS button in the center display's Function view to activate/deactivate the function
The indicator light illuminates on the side of thevehicle where the system has detected anothervehicle. If your vehicle is passed on both sides atthe same time, both lights will illuminate.
Principle for Blind Spot Information: Zone 1. Blind area, Zone 2. Area for approaching/passing vehicles
Blind Spot Information functions when your vehi- cle is moving at speeds above approx. 6 mph(10 km/h). Blind Spot Information is designed to react to:
• vehicles that are passing your vehicle
• other vehicles that are rapidly approaching your vehicle
When Blind Spot Information detects a vehicle inzone 1 or a fast-approaching vehicle in zone 2,the indicator light in the respective door mirrorwill glow steadily. If the driver then uses the turn signal on the side on which the warning is given, the indicator lightwill begin flashing and become brighter.

Cross Traffic Alert (CTA) * limitations
CTA functionality may be reduced in certain sit- uations.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors may reduce the system's function or make itimpossible to detect other vehicles orobjects.
• CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.
MaintenanceThe CTA sensors are located on the inside of therear fenders/bumper.

Road Sign Information (RSI) *
RSI is a feature that helps the driver see road signs showing the posted speed limit.
Examples of readable road signs
If the vehicle passes a sign showing the speed limit, this will be displayed in the instrument panel and the head-up display *.
NOTE
If the vehicle is equipped with the Sensus Navigation 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 is only intended to provide supplementary infor-mation. The driver is always responsible for operating the vehicle safely.

Driver Alert Control limitations
Driver Alert Control (DAC) may have limited or reduced functionality in certain situations.
WARNING
A driving pattern may not change despite driver fatigue, e.g., if a function such as PilotAssist is being used, which means that DACwill not provide a warning. It is always veryimportant to stop and take a break at the firstsign of driver fatigue, even if the system hasnot provided a warning.
In certain situations, DAC may provide warnings even if the driver

Driving lane assistance provides vibrations in the steer- ing wheel7
.
Depending on the settings used, Lane Keeping Aid functions in different ways:
• Assistance type
Assist8
is activated: when
the vehicle approaches a traffic lane marker line, LKA will provide active steering assis-tance to help steer it back into the lane.
• Assistance type
Warning8
is activated: if the
vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steer-ing wheel will be provided.
NOTE
If the turn signal is used, Lane Keeping Aid will not provide an alert or steering assis-
tance.
WARNING
Lane Keeping Aid is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
Steering assistanceIn 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 until
steering 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
Traffic lane assistance does not react
The traffic lane assistance system does not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, the traffic lane system will not react if the vehicle crosses a lane marker
line.
7 The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:

LimitationsIn 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 marker lines
• 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 to assist the driver and does not function inall driving, weather, traffic or road condi-tions.

Park Assist limitations
The Park Assist system has certain limitations.
NOTE
A trailer hitch whose wiring is integrated with the 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 ensure that 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.
