Pilot Assist *53
Pilot Assist can help the driver keep the vehi- cle in the current traffic lane and maintain aneven speed and a set time interval to thevehicle ahead.
Get to know Pilot Assist
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings.

Pilot Assist helps to steer the vehicle, and you may need to drive a few miles with Pilot Assistbefore you feel completely at home with the function. It is important to be familiar with all of the function's applications and limitations in order to take advantage of all it has to offer. The Pilot Assist function is primarily intended for use on highways and other major roadswhere it can help provide a more comfortableand relaxing driving experience. The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors thedistance to the vehicle ahead and the trafficlane's side markers using the camera. The sys-tem maintains the set time interval to the vehi-cle ahead by automatically adjusting your vehi-cle's speed and keeps your vehicle in its laneby providing steering assistance. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed. Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emita slight sound when they are being used toadjust speed. Pilot Assist is designed to:
smoothly regulate speed. The driver must apply the brakes in situations requiringimmediate braking. For example, whenthere are great differences in speedbetween vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the camera and radar sensor, braking mayoccur unexpectedly or not at all.
follow a vehicle ahead in the same laneand maintain a time interval to that vehicleset by the driver. If the radar sensor doesnot detect a vehicle ahead, it will insteadmaintain the speed set by the driver. Thiswill also happen if the speed of the vehicleahead exceeds the set speed for your vehi-cle.
The vehicle's position in the traffic
lane
When Pilot Assist helps to steer, it attempts toposition the vehicle halfway between the visi-ble lane marking lines. For a smoother drive, itis a good idea to allow the vehicle to find agood position. The driver can always adjustthe position him/herself by increasing steeringinput. It is important for the driver to makesure the vehicle is positioned safely in the lane. If Pilot Assist does not position the vehicle appropriately in the lane, the driver should turnoff Pilot Assist or switch to Adaptive Cruise Control *.

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
