Steering assistanceThe color of the steering wheel symbol indicates thecurrent status of steeringassistance: • GREEN indicates that steering assistance is active
• GRAY (as shown in illustration) indicates thatsteering assistance is deactivated.
Pilot Assist's steering assistance is based on monitoring the direction of the vehicle aheadand the traffic lane's side marker lines. Thedriver can override Pilot Assist's steering rec-ommendations at any time and steer inanother direction, e.g. to change lanes or avoidobstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist isunable for some other reason to clearly inter-pret the lane, Pilot Assist will temporarilydeactivate steering assistance until it can onceagain interpret the lane markings. However,the speed and distance warnings will remainactive. The driver will be alerted by slightvibrations in the steering wheel that the func-tion has been temporarily deactivated.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steer-ing assistance from Pilot Assist, but insteadshould always be ready to increase his or herown steering efforts, particularly in curves. When the vehicle is approaching an off-ramp or a fork in the road, the driver should steertoward the desired lane so that Pilot Assistcan detect the desired direction of travel.
Hands on the steering wheelPilot Assist only functions if the driver's handsare on the steering wheel. It is also importantfor the driver to always continue to be activeand alert when driving since Pilot Assist isunable to read all situations and may togglebetween off and on without prior warning.
If Pilot Assist detects that thedriver's hands are not on thesteering wheel, the systemwill provide a symbol and atext message in the instru-ment panel to instruct thedriver to actively steer the
vehicle.
If the driver's hands are still detected on the steering wheel after a few seconds havepassed, the instructions to actively steer thevehicle will be repeated, accompanied by anaudible signal. If Pilot Assist still does not detect the driver'shands on the steering wheel after a few moreseconds have passed, the audible signal willbecome intense and the steering function willswitch off. Pilot Assist must then be reactiva- ted by pressing the
button on the steering
wheel.
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.

standby mode
Pilot Assist can be deactivated and put in standby mode. This may happen automati-cally or be due to driver intervention.
Standby mode means that the function is selected in the instrument panel but not acti-vated. In standby mode, Pilot Assist will notregulate the speed or distance to the vehicleahead or provide steering assistance.
Standby mode due to action by the
driver
Pilot Assist will be deactivated and put instandby mode if any of the following occurs:
The brakes are applied.
The gear selector is moved to
N.
A turn signal is used for more than1 minute.
The vehicle is driven faster than the setspeed for more than 1 minute.
Automatic standby mode
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a mes-sage on the instrument panel.
The driver must then regulate vehicle speed, apply the brakes if necessary,and maintain a safe distance to othervehicles.
The function may automatically go intostandby mode if one of the following occurs. One of the systems that Pilot Assist isdependent on stops working, such as Electronic Stability Control 60

Pilot Assist steering assistance can be tem- porarily deactivated and reactivated withoutprior warning.
When the turn signals are used, Pilot Assist's steering assistance will be temporarily deacti-vated. When the direction indicator is turnedoff, steering assistance is reactivated automat-ically if the lane's edge markings can still bedetected. If Pilot Assist cannot clearly interpret the lane's side marker lines or if the camera/radarsensor is unable for some other reason toclearly interpret the lane, Pilot Assist will tem-porarily deactivate steering assistance. How-ever, the speed and distance warnings willremain active. Steering assistance will resumewhen the side marker lines can once again beinterpreted. In these situations, the driver maybe alerted through slight vibrations in thesteering wheel that steering assistance is tem-porarily deactivated.

limitations
Pilot Assist functionality may be reduced in certain situations.
Pilot Assist is a driver support function designed to simplify driving and assist thedriver in many situations. However, the driveris always responsible for maintaining a suita-ble distance to vehicles or objects around itand ensuring that the vehicle is correctly posi-tioned in the traffic lane.
WARNING
In some situations, Pilot Assist may have trouble helping the driver properly or maybe deactivated automatically – we adviseagainst using Pilot Assist in such cases.Examples of such situations include:
the lane markings are unclear, worn, missing, cross each other, or there aremultiple sets of road markings.
the lane division changes, e.g. whenlanes split or merge, and at off-ramps.
when there is road construction andsudden changes to the road surface,e.g. when the lines may no longer markthe correct route.
edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edgesor strong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibil-
ity with poor light conditions, back- lighting, wet road surface, etc.
The driver should also note that Pilot Assist has the following limitations:
High curbs, roadside barriers, tempo- rary obstacles (traffic cones, safety bar-riers, etc.) are not detected. Alterna-tively, they may be detected incorrectlyas lane markings, with a subsequentrisk of contact between the vehicle andsuch obstacles. The driver is responsi-ble for ensuring that the vehicle main-tains a suitable distance from suchobstacles.
The camera and radar sensors do nothave the capacity to detect all oncom-ing objects and obstacles in trafficenvironments, e.g. potholes, stationaryobstacles or objects that completely orpartially block the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The steering assistance is limited inforce, which means that Pilot Assistcannot always help the driver to steerand keep the vehicle within the lane.
In vehicles equipped with Sensus Navigation
*, the function is able to use
