WARNING
•City Safety is a supplementary driving aid and does not function in all driving situa-tions or in all traffic, weather or road con-ditions.
• Warnings and braking for an approachingvehicle will usually come at a very latestage.
• The driver is responsible for maintaining asafe distance and speed. Never wait for awarning or for City Safety to take action.
LimitationsIn certain situations, it may be very difficult for City Safety to help the driver avoid a collision withan approaching vehicle in crossing traffic, forexample:
• on slippery roads when Electronic Stability Control is active
• if the approaching vehicle is detected at alate stage
• If the approaching vehicle is partiallyobscured by another vehicle
• if the approaching vehicle moves erratically(e.g., sudden lane changes at a late stage)

Rear Collision Warning (RCW)
The
Rear Collision Warning with braking at
standstill (RCW) function can help the driver
avoid rear-end collisions.
RCW is activated automatically each time the engine is started and cannot be turned off. RCW can warn the driver of a vehicle approach- ing yours from behind by rapidly flashing yourrear turn signals. RCW is only activated when a vehicle is rapidly approaching your vehicle from behind. At speeds below 20 mph (30 km/h), if RCW determines that your vehicle is at risk of a rear-end collision, the front seat belt pretensionersand the Whiplash Protection System are acti-vated. Just prior to the collision, the brakes are also applied to help reduce your vehicle's forwardmovement if and when the collision occurs. How-ever, this can only happen if your vehicle is sta-tionary. The brakes will be released immediately if the accelerator pedal is pressed.
NOTE
• Due to local traffic regulations in certain markets, RCW will
not activate the rear
turn signals. That part of the function will be deactivated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section
"Setting a warning level (distance)" in the article "City Safety settings."
• If RCW detects a vehicle approachingfrom behind, the seat belt pretensionersand Whiplash Protection System will beactivated.
LimitationsIn some circumstances, it may be difficult for RCW to help the driver if there is a risk of a colli-sion, such as: •
In slippery conditions when Electronic Stability Control is active
• If the vehicle approaching from the rear isdetected at a late stage
• If the vehicle approaching from the rearchanges lanes at a late stage
• If the vehicle approaching from the rear ismoving at a speed above approx. 50 mph(80 km/h)

City Safety limitations
City Safety ™ may have limited or reduced func-
tionality in certain situations.
The function has several limitations that the driver should be familiar with:
Low objects
Hanging objects, such as flags for overhanging loads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood may limit City Safety's func-tion.
Slippery driving conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In situations of this type, the ABSbrakes and Electronic Stability Control will helpprovide braking power and stability.
Backlighting
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is notlooking straight ahead may make the visual warn-ing signal in the windshield difficult to see.
Heat
If the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically. The visual warning signal may also be temporarilydisabled due to high passenger compartmenttemperatures caused by strong sunlight. Warnings may not be given if the distance to the vehicle ahead is short and the driver is activelyoperating the vehicle (clearly depressing a pedalor turning the steering wheel).
Reduced visibility
City Safety's functions may be greatly impeded or deactivated by e.g., intense snowfall or rain, indense fog, in very dusty conditions or if there isblowing snow in front of the vehicle. Condensa-tion, ice, snow or dirt on the windshield may alsoreduce the system's functionality.
NOTE
•
Keep the windshield in front of the radar sensor free of ice, snow, dirt, etc.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sensor.Keep the hood free of ice and snow.
• Do not mount or in any way attach any-thing on the windshield that couldobstruct the radar sensor.

Park Assist *
The Park Assist system is designed to assist you
when driving into parking spaces, garages, etc. An audible signal and symbols in the instrumentpanel and center display indicate the distance tothe object.
Display view showing object zones and sensor sectors
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The highlighted sector shows which of the sen- sors has detected the object. The closer thehighlighted sector is to the vehicle symbol, thecloser the actual object is to your vehicle. The Park Assist system uses an intermittent tone that pulses faster as you come closer to anobject. Sound from the infotainment system willbe temporarily turned down.

Using Park Assist Pilot (PAP) *
Park Assist Pilot (PAP) gives the driver instruc- tions during the parking procedure.
Symbols, images and text in the center display indicate when the various steps in the parkingprocedure will be carried out. PAP can be activated if the following conditions are met after the engine has started:
• The vehicle may not be towing a trailer.
• The vehicle's speed must be below approx. 30 mph (50 km/h).
NOTE
If a trailer hitch is configured in the vehicle's electrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.
ParkingProcedure for parking:
1. The system searches for and measures a
possible parking space.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle's position is adjusted in the park- ing space by moving forward and rearward.
1: Searching and measuring
Parallel parking
Perpendicular parking
PAP searches for a potential parking space and measures it to see if there is sufficient space foryour vehicle. To start this procedure: 1. Tap the
Park Assist button
in the center display's Function view. If necessary, slow down toa speed below 20 mph (30km/h) for parallel parking orapprox. 12 mph ( 20 km/h) forperpendicular parking.
2. Keep an eye on the display and be prepared to stop the vehicle when you are instructed by PAP to do so.
3. Select
Parallel parking or Perpendicular
parking and put the transmission in reverse.
4. Keep an eye on the display and be prepared to stop the vehicle when you are instructed by PAP to do so.
5. Stop the vehicle when instructed to do so.
NOTE
PAP normally searches for available parking spaces along the curb on the right (passeng-er's) side of the vehicle. However, it can alsoassist in finding and parking in spaces on thedriver's side. To do so:
• Activate the left turn signal. PAP will then search for a parking space on the leftside of the vehicle.

Overview
Blind Spot Information indicators
Indicator light
Blind Spot Information symbol
The indicator light illuminates on the side of the vehicle 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 in zone 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.
WARNING
• Blind Spot Information does not function in sharp curves.
• Blind Spot Information does not functionwhen your vehicle is backing up.

Driving lane assistance
The
Lane Departure Warning (LDW) and Lane
Keeping Aid (LKA) * functions are designed to
help reduce the risk of accidents in situations where the vehicle unintentionally leaves its laneon highways or other major roads.
Driving lane assistance systems: LDW
or LKA
There are two versions of the driving lane assis- tance system:
• LDW (
Lane Departure Warning): provides
an audible signal or vibrations in the steering wheel.
• LKA (
Lane Keeping Aid): actively steers the
vehicle to help keep it in its traffic lane and/or alerts the driver using an audible sig-nal or through vibrations in the steeringwheel.
The driving lane assistance systems are active at speeds from approx. 40 mph (65 km/h) up to thevehicle's permitted top speed on roads withclearly visible traffic lane marker lines. On narrow roads, the systems may not function and will go into standby mode. They will return toactive mode if the road becomes sufficientlywide.
A camera monitors the road/traffic lane's marker lines
Both LDW and LKA provide vibrations in the steering wheel 6
LKA attempts to steer the vehicle back into its lane
Depending on the version and settings used, driving lane assistance functions in differentways:
• If the system is activated (either LDW or LKA): if the driver does not react and thevehicle is moving out of its traffic lane, anaudible signal and/or vibrations in the steer-ing wheel will be provided.
• If the system is activated (LKA only): whenthe vehicle approaches a traffic lane markerline, LKA will provide active steering assis-tance to help steer it back into the lane.
6
The level of vibrations varies; the longer the vehicle is over a lane marker line, the greater the number of vibrations:

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.339
NOTE
If the turn signal is used, neither of the driving lane assistance systems (LDW or LKA) willprovide an alert or steering assistance.
WARNING
This feature 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 assistance (LKA only)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 this is not the case, this sym-bol will illuminate in the instru- ment panel and
Lane Keeping
Aid Apply steering will appear
to alert the driver to actively steer the vehicle.
If the driver does not take action, an audible sig- nal will sound and LKA will go into standby mode.The function will not become available again untilthe driver actively steers the vehicle.
Dynamic cornering
The traffic lane assistance systems do not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, neither of the traffic lanesystems will react if the vehicle crosses a lanemarker line.
LimitationsIn certain demanding driving situations, the driv-ing lane assistance functions may not be able toassist the driver. In these situations, it may beadvisable to turn the function off. Examples of these situations: • road construction
• poor road surfaces
• edges or lines other than the lane's marker lines
• a very active driving style •
winter driving conditions
• bad weather with reduced visibility
The driving lane assistance function use the vehi- cle's camera, which has general limitations. Seethe article "Camera limitations."
