Adaptive Cruise Control* - Queue Assist
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain aneven speed and a safe distance from the vehi-cle ahead. Queue Assist also provides theAdaptive Cruise Control with enhanced func-tionality at speeds below 30 km/h.. In cars with automatic gearbox the adaptive cruise control is supplemented with theQueue Assist function (also referred to as"Queue Assist"). Queue Assistant has the following functions:
• Extended speed range - also below 30 km/h and when stationary
• Change of target
• Automatic braking ceases when station-ary
• Automatic activation parking brake.
Note that the lowest programmable speed for the adaptive cruise control is 30 km/h - eventhough it is capable of following another vehi-cle down to a standstill, a lower speed can-
not be selected.
Extended speed range
NOTE
In order to activate the cruise control the driver's door must be closed and the drivermust be wearing the seatbelt.
With an automatic gearbox, the adaptive cruise control can follow another vehiclewithin the range 0-200 km/h.
NOTE
Activation of the cruise control below 30 km/h requires a vehicle in front within areasonable distance.
For shorter stops in connection with inching in slow traffic or at traffic lights driving isautomatically resumed if the stops do notexceed about 3 seconds - if it takes longerbefore the car in front starts moving againthen the Adaptive cruise control is set instandby mode with automatic braking. Thedriver must then reactivate it in one of the fol-lowing ways:
• Press the steering wheel button
.
or
• Depress the accelerator pedal.
> The cruise control will then resume fol- lowing the vehicle in front.
NOTE
Queue Assist can hold the car stationary for a maximum of 4 minutes - then theparking brake is applied and Cruise Con-trol is disengaged.
• The driver has to release the parking brake before the cruise control can bereactivated.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When the adaptive cruise control is following another vehicle at speeds below 30 km/h and
changes target from a moving to a stationaryvehicle, the cruise control will slow down forthe stationary vehicle.

WARNING
When the cruise control is following another vehicle at speeds in excess of
30 km/h and the target is changed from amoving vehicle to a stationary vehicle, thecruise control will ignore the stationaryvehicle and instead select the storedspeed. • The driver must intervene him/herself and brake.
Automatic standby mode with change of target
The adaptive cruise control is disengaged and set in standby mode:
• when the speed is below 5 km/h and cruise control is not sure whether the tar-get object is a stationary vehicle or someother object, e.g. a speed bump.
• when the speed is below 5 km/h and thevehicle in front turns off so the cruisecontrol no longer has a vehicle to follow.
Termination of automatic braking at a
standstill
In certain situations, Queue Assist stops automatic braking at a standstill. This meansthat the brakes are released and the car maystart to roll - the driver must therefore inter-vene and brake the car himself/herself inorder to maintain its position. Queue Assist releases the foot brake and setsthe adaptive cruise control in standby modein the following situations:
• the driver puts his/her foot on the brake pedal
• the parking brake is applied
• the gear selector is moved to
P, N or R
position
• the driver sets the cruise control instandby mode.
Automatic activation parking brakeIn certain situations Queue Assist applies the parking brake in order to keep the car remain-ing stationary. This takes place if:
• the driver opens the door or takes off his/her seatbelt
• DSTC is changed from
Normal to Sport
mode
• Queue Assist has held the car stationaryfor more than 4 minutes
• the engine is switched off
• the brakes have overheated.

If the speed difference is 4-15 km/h in relation to the vehicle in front then City Safety™ cancompletely prevent a collision. City Safety™ activates a short, sharp braking and stops the car in normal circumstances,just behind the vehicle in front. For most dri-vers this is well outside normal driving styleand may be experienced as being uncomfort-able. If the difference in speed between the vehi- cles is greater than 15 km/h then CitySafety™ may not prevent the collision on itsown. To obtain full brake force, the drivermust depress the brake pedal. This couldthen make it possible to prevent a collision,even at speed differences above 15 km/h. When the function is activated and brakes,the combined instrument panel shows a textmessage to the effect that the function is/hasbeen active.
NOTE
When City Safety™ brakes, the brake lights come on.

City Safety™ - operation
City Safety™ is a function for helping the driver to avoid a collision when driving inqueues, amongst other things, when changesin the traffic ahead, combined with a lapse inattention, could lead to an incident.
On and Off
NOTE
The City Safety™ function is always switched on after the engine has beenstarted via key position
I and II (p. 70).
In certain situations, it may advisable to disa- ble City Safety™, e.g. where leafy branchescould sweep over the bonnet and/or wind-screen. After starting the engine City Safety™ can be deactivated as follows: The function can beactivated/deactivated in the menu system MY
CAR . For a description of the menu system,
see MY CAR (p. 103). However, the function will be enabled the next time the engine is started, regardless ofwhether the system was enabled or disabledwhen the engine was switched off.

"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid toassist the driver when there is a risk of collid-ing with a pedestrian, bicycle or vehicle infront that are stationary or moving in the samedirection.
The function uses the car's camera sensor,
which has certain limitations. The car’s camera sensor is also used - as well as by Collision Warning with Auto Brake- by the functions:
• Automatic main/dipped beam dim- ming (p. 82)
• Road sign information (p. 179)
• Driver Alert Control - DAC (p. 224)
• Lane Keeping Aid (p. 229)
NOTE
Keep the windscreen surface in front of the camera sensor free from ice, snow, mistand dirt. Do not stick or attach anything to the windscreen in front of the camera sensoras this may reduce effectiveness or causeone or more of the systems dependent onthe camera to stop working.
The camera sensors have limitations similar to the human eye, i.e. they "see" worse in darkness, heavy snowfall or rain and in thickfog for example. Under such conditions thefunctions of camera-dependent systemscould be significantly reduced or temporarilydisengaged. Strong oncoming light, reflections in the car- riageway, snow or ice on the road surface,dirty road surfaces or unclear lane markingscould also significantly reduce camera sensorfunction when it is used to scan the carriage-way and detect pedestrians and other vehi-cles. The field of vision of the camera sensor is lim- ited, which is why pedestrians, cyclists andvehicles cannot be detected in some situa-tions, or they are detected later than anticipa-ted. During very high temperatures the camera is temporarily switched off for about 15 minutesafter the engine is started in order to protectcamera functionality.
Fault tracing and actionIf the display shows the messageWindscreen Sensors blocked then this
means that the camera sensor is blocked and cannot detect pedestrians, cyclists, vehiclesor road markings in front of the car. At the same time, this means that - besides Collision Warning with Auto Brake - the Auto-matic main/dipped beam dimming, Road SignInformation, Driver Alert Control and Lane

Driver Alert System*
The Driver Alert System is intended to assist drivers whose driving ability is deteriorating orwho are inadvertently leaving the lane they aredriving on. The Driver Alert System consists of different functions which can either be switched on atthe same time or individually:
• Driver Alert Control - DAC (p. 225).
• Lane Departure Warning - LDW (p. 229).
• Lane Keeping Aid - LKA (p. 234)
A switched-on function is set in standbymode and is not activated automatically untilspeed exceeds 65 km/h. The function is deactivated again when speed decreases to below 60 km/h. Both functions use a camera which is dependent on the lane having side markingspainted on each side.
WARNING
Driver Alert System does not work in all situations but is designed merely as a sup-plementary aid. The driver always bears ultimate responsi- bility for ensuring that the vehicle is drivensafely.

Driver Alert Control (DAC)*
The DAC function is intended to attract the driver's attention when he/she starts to driveless consistently, e.g. if he/she becomes dis-tracted or starts to fall asleep. The objective for DAC is to detect slowly deteriorating driving ability and it is primarilyintended for major roads. The function is notintended for city traffic.
A camera detects the side markings painted on the carriageway and compares the sectionof the road with the driver's steering wheelmovements. The driver is alerted if the vehicledoes not follow the carriageway evenly. In some cases driving ability is not affected despite driver fatigue. In which case theremay not be any warning issued for the driver.For this reason it is always important to stopand take a break in the event of any signs of

WARNING
PAP does not work in all situations but is designed merely as a supplementary aid. The driver always has the final responsibil- ity for driving the vehicle in a safe mannerand for paying attention to the surround-ings and other road users approaching orpassing during parking.

Park Assist Pilot (PAP)* - function
The Park Assist Pilot (PAP – Park Assist Pilot) helps the driver to park by first checkingwhether a space is sufficiently large and thenturning the steering wheel and steering thecar into the space. The combined instrumentpanel uses symbols, graphics and text toshow when different operations should beperformed.
NOTE
The PAP function measures the space and turns the steering wheel - the driver's taskis to follow the combined instrument pan-el's instructions and select the gear(reverse/forward), control the speed, brakeand stop.
PAP can be activated if the following criteria are met once the engine has been started:
• The functions DSTC or ABS must not intervene while the PAP function is ena-bled - these can be activated due to asteep or slippery surface, for example;see the sections on Foot brake and Sta-bility and traction control system for moreinformation.
• A trailer must not be connected to thecar.
• The speed must be below 50 km/h.
Principle for PAP.
The PAP function parks the car using the fol- lowing steps:
1. The function searches for a parking space and measures it (A & B) - during measure- ment the speed must notexceed 30 km/h.
2. The car is steered into the space while reversing (C & D).
3. The car is straightened up in the space by driving back and forth (E & F ).

2 - Reversing in
During the Reversing step, PAP will steer the car into the parking space. Proceed as fol-lows:
1. Check that the area behind the car is
clear, then engage reverse gear.
2. Reverse slowly and carefully without touching the steering wheel - and no faster than approx. 7 km/h.
3. Keep an eye on the combined instrument panel and be prepared to stop the carwhen the graphics and text so request.
NOTE
•Keep your hands away from the steer- ing wheel when the PAP function isactivated.
• Make sure that the steering wheel isnot hindered in any way and can rotatefreely.
• For optimum results - Wait until thesteering wheel has been turned beforestarting to drive backwards/forwards.
3 - Straightening up
When the car has reversed into the parking space, it must be straightened up and stop-ped. 1. Engage 1st gear or
D position, wait until
the steering wheel has been turned, then drive slowly forwards.
2. Stop the car when the graphics and text message so request.
3. Engage reverse gear and drive back- wards slowly until the graphics and textmessage tell you to stop.
The function is disengaged automatically when parking is complete, and the graphicsand text message show that parking is com-plete. It may be necessary for the driver tocorrect the positioning afterwards. Only thedriver can determine whether the car is prop-erly parked.
IMPORTANT
The warning distance is shorter when the sensors are used by Active Park Assistcompared with when Park Assist uses thesensors.

Park Assist Pilot (PAP)* - limitations
The Park Assist Pilot (PAP – Park Assist Pilot) helps the driver to park by first checkingwhether a space is sufficiently large and thenturning the steering wheel and steering thecar into the space. The combined instrumentpanel uses symbols, graphics and text toshow when different operations should beperformed. The PAP sequence is stopped:
• if the car is driven too quickly - above 7 km/h
• if the driver touches the steering wheel
• if the ABS or DSTC function is enabled -e.g. if a wheel loses grip on a slipperyroad surface.
A text message indicates why the PAP sequence was stopped.
NOTE
Dirt, ice and snow covering the sensors will reduce their function and may preventmeasurement.
IMPORTANT
Under certain circumstances, PAP is unable to find parking spaces - one reasonfor this may be the fact that there is inter-ference with the sensors from externalsound sources which emit the same ultra-sound frequencies as those with which thesystem works. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakesand exhaust noises from motorcycles etc.
To bear in mindThe driver should bear in mind that the Park Assist Pilot is an aid - not an infallible, fully-automatic function. The driver must thereforebe prepared to intervene. There are also sev-eral details to bear in mind while parking, e.g.:
• PAP starts out from the current location of the parked vehicles - if they are inap-propriately parked then the car's tyresand wheel rims may be damaged againstkerbs.
• PAP is designed for parking on straightstreets - not sharp bends or turns in theroad. For this reason, make sure the caris parallel to the parking space when PAPmeasures the space.
• It is not always possible to find parkingspaces on narrow streets since there isnot enough space for manoeuvring. Insuch parking situations, it helps the sys- tem to drive as close to the side of theroad as possible where you intend topark.
• Bear in mind that the front of the car mayswing out towards oncoming traffic whilebeing parked.
• Objects situated higher than the detectionarea of the sensors are not included whencalculations are made for the parkingmanoeuvre. This may cause PAP toswing into the parking space too early -for this reason, such parking spacesshould be avoided.
• The driver is responsible for determiningwhether the space selected by PAP issuitable for parking.
• Use approved tyres 24
with the correct tyre
pressure - this affects PAP's ability topark the car.
• Heavy rain or snow may cause the sys-tem to measure the parking space incor-rectly.
• Do not use PAP if snow chains or the
spare wheel are fitted.
• Do not use PAP if loaded objects are pro-truding from the car.
24
"Approved tyres" refers to tyres of the same type and make as those fitted new on delivery from the factory.
