information from map data, which could cause variations in performance.
Pilot Assist will be switched off if thespeed-dependent power steeringwheel resistance is working at reducedpower, e.g. during cooling due to over-heating.
WARNING
Pilot Assist should only be used if there are clear lane lines painted on each side of thelane. All other use will increase the risk ofcontact with nearby obstacles that cannotbe detected by the functions.
WARNING
This is not a collision avoidance sys- tem. The driver is always responsibleand must intervene if the system failsto detect a vehicle ahead.
The function does not brake for peopleor animals and does not brake for smallvehicles, such as bikes and motorcy-cles. Similarly, it does not brake for lowtrailers, oncoming, slow-moving or sta-tionary vehicles and objects.
Do not use the function in demandingsituations, such as in city traffic, atintersections, on slippery surfaces,with a lot of water or slush on the road,in heavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
The driver can always correct or adjust steer-ing assistance provided by Pilot Assist by turn-ing the steering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be drivenon flat roads. The function may not be able tomaintain the correct time interval to the vehi-cle ahead when driving down steep hills. Thedriver should be extra attentive and preparedto apply the brakes. Do not use Pilot Assist if the vehicle is carryinga heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Drive mode unavailableThe Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

WARNING
The driver should be aware that if condi- tions suddenly change when using PassingAssistance, the function may implement anundesired acceleration in certain condi-tions. Some situations should be avoided, e.g. if: the vehicle is approaching an exit in the same direction as passing would nor-mally occur
the vehicle ahead slows before yourvehicle has had time to switch to thepassing lane
traffic in the passing lane slows down
Situations of this type can be avoided by temporarily putting Adaptive Cruise Controlor Pilot Assist in standby mode.

Collision risk warning from driver support
The driver support systems Adaptive Cruise Control * and Pilot Assist * can help alert the
driver if the distance to the vehicle ahead suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a sit-uation requires more braking force than driversupport can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert thedriver that immediate action is required.
WARNING
The driver support system only issues a warning for vehicles detected by its radarunit – thus, a warning may come after adelay or not at all. Never wait for a warning.Apply the brakes when necessary.
Collision warning symbol on the windshield
In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.

WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all.
Never wait for a warning or assistance. Apply the brakes when necessary.
NOTE
Driver support can keep the vehicle sta- tionary for no more than 5 minutes – afterthat time the parking brake is applied andthe function is deactivated. The parking brake must be released before driver support can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, auto-hold will be deacti- vated when the vehicle is at a standstill andthe function will go into standby mode. This means that the brakes will be released and the vehicle could begin to roll. The driver mustactively apply the brakes to keep the vehiclestationary. This can occur if:
The driver depresses the brake pedal.
The parking brake is applied.
The gear selector is moved to the
P, N or
R position.
The driver puts Adaptive Cruise Control or Pilot Assist in standby mode.
Auto Activate Parking BrakeThe parking brake will be applied if the func-tion is keeping the vehicle stationary using thebrakes and:
The driver opens the door or unbuckleshis/her seat belt.
The function has kept the vehicle at astandstill for more than approx. 5 minutes.
The brakes overheat.
The driver switches off the engine.

Lane Keeping Aid
Lane Keeping Aid (LKA 69
) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.
Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
A camera monitors the road/traffic lane's marker lines.

City Safetyâ„¢
City Safety 75
can alert the driver with light,
sound and pulsations in the brake pedal to help the driver detect pedestrians, cyclists,large animals and vehicles.
Function overview
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
The function can help the driver avoid a colli- sion in e.g. stop-and-go traffic, when changesin the traffic ahead and driver distraction couldlead to an incident. City Safety activates abrief, forceful braking in an attempt to stopyour vehicle immediately behind the vehicle orobject ahead. The function assists the driver by automati-cally applying the brakes if there is an immi-nent risk of a collision and the driver does notreact in time by braking and/or steering away. City Safety is activated in situations in which the driver should have applied the brakesmuch earlier, which means that the systemwill not be able to assist the driver in all situa-tions. The function is designed to be activatedas late as possible to help avoid unnecessaryintervention. Automatic braking will only beapplied after or during a collision warning. Normally, the occupants of the vehicle will not be aware of City Safety except when the sys-tem intervenes when a collision is imminent.
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.

Limitations of City Safety in crossing traffic
In certain situations, it may be difficult for
City Safety to help the driver avoid a collisionwith crossing traffic.
For example:
On slippery roads when Electronic Stabil- ity Control (ESC) is actively operating.
If an approaching vehicle is detected at alate stage.
If the oncoming vehicle is partiallyobstructed by another vehicle or object.
If the oncoming vehicle's headlights areoff.
If the oncoming vehicle is moving errati-cally and e.g. suddenly changes lanes at alate stage.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Important warnings
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all. Never wait for a warning or assistance. Apply the brakes when necessary.
WARNING
Warnings and brake interventions can be triggered late or not at all if the traf-fic situation or external influences pre-vent the camera and radar unit fromproperly detecting pedestrians,cyclists, large animals or vehiclesahead of the vehicle.
To be able to detect vehicles at night,its front and rear lights must work andilluminate clearly.
The camera and radar unit have a lim-ited range for pedestrians and cyclists– the system can provide effectivewarnings and brake interventions if therelative speed is lower than 50 km/h(30 mph). For stationary or slow-mov-ing vehicles, warnings and brake inter-ventions are effective at vehicle speedsof up to 70 km/h (43 mph). Speedreduction for large animals is less than15 km/h (9 mph) and can be achievedat vehicle speeds over 70 km/h(43 mph). At lower speeds, the warn-ing and brake intervention for large ani-mals is less effective.
Warnings for stationary or slow-mov-ing vehicles and large animals can bedisengaged due to darkness or poorvisibility.
Warnings and brake interventions for pedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anythingon the inside or outside of the wind-shield, or in front of or around the cam-era and radar unit – this could disruptcamera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce thefunction, disengage it completely orgive an improper function response.

WARNING
The City Safety auto-brake function can prevent a collision or reduce colli-sion speed, but to ensure full brakeperformance the driver should alwaysdepress the brake pedal – even whenthe car auto-brakes.
The warning and steering assistanceare only activated if there is a high riskof collision – you must therefore neverwait for the collision warning or CitySafety to intervene.
Warnings and brake interventions forpedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
City Safety does not activate auto-braking intervention during heavyacceleration.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Rear Collision Warning *85
The Rear Collision Warning 86
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.

However, as you back your vehicle slowly out of a parking space, CTA's field of vision changes in relation to the obstructing vehicle/object and its blind zone is reduced.
Examples of further limitations

The
auto brake subfunction only detects
vehicles in motion and may therefore not
"see" and brake for e.g. stationary obsta- cles, a cyclists or a pedestrian.
Dirt, ice and snow covering the sensorsmay reduce functionality and prevent thesystem from providing warnings.
CTA is automatically deactivated if atrailer, bicycle holder or similar is con-nected to the vehicle's electrical system.
For CTA to function effectively, bicycleholders, luggage racks or similar shouldnot be mounted on the vehicle's towbar.
