Collision warning
Warning light
Pilot Assist can exert brake force that is equiva-lent to approximately 40% of the vehicle's totalbraking capacity.
In situations requiring more brake force than PilotAssist can provide and if the driver does notapply the brakes, an audible signal from the CitySafety system will sound and warning light willilluminate in the windshield to alert the driver toreact.

A flashing symbol alerts the driver
If the vehicle is equipped with a head-up display,a flashing symbol in the windshield will alert thedriver.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.
WARNING
Pilot Assist only provides warnings for vehi-cles that its radar sensor and camera havedetected. For this reason, a warning may begiven later than expected or not at all. Thedriver should never wait for a warning beforeapplying the brakes.

Prerequisites
The prerequisites for activating Pilot Assist are:
•The vehicle ahead must be within a reasona-ble (detectable) distance
•The camera must be able to clearly detectthe traffic lane's side marker lines
•The vehicle's speed must be under approx.30 mph (50 km/h).
A WHITE symbol indicates thatPilot Assist has been selected.
In other cases, the WHITEarrow pointing to the right indi-cates that the system is availa-ble.
A YELLOW symbol with a flashing WHITE arrowindicates that the system is about to shift intostandby mode.
With ACC in standby mode:
1.Tap ▶ (6).
>The symbol will be displayed and PilotAssist will go into standby mode.
2.Press the button (2) on the left-sidesteering wheel keypad.
>Pilot Assist will go into active mode.

WARNING
Pilot Assist is not a collision avoidance sys-tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle.
Do not use Pilot Assist in demanding drivingconditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps.
In certain situations, it may be difficult for PilotAssist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
•the lane's side market lines are missing,badly faded or cross each other.
•the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
•there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
•the lane is narrow or winding.
•the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that PilotAssist has the following limitations:
•High curbs, barriers and temporary obsta-cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
•The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
•Pilot Assist does not "see" pedestrians,animals, etc.
•Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.

Hands on the steering wheel
Pilot Assist only functions when the driver'shands are on the steering wheel, which is con-tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound.
If the driver does not return his/her hands to thesteering wheel after the audible signal, PilotAssist will go into standby mode and must be
reactivated by pressing .

Setting a Pilot Assist-1 time interval
Different time intervals to the vehicle ahead canbe selected and are shown in the instrumentpanel as 1–5 horizontal bars.

Changing the time interval
The greater the number of bars,the longer the time interval.One bar between the vehiclesrepresents a time interval ofapproximately 1 second; 5 barsis approximately 3 seconds.
The same symbol appears if Distance Alert isactivated.
Time interval controls
Press to reduce the time interval to the vehi-cle ahead
Press to increase the time interval to thevehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
•If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.

Automatic braking with PilotAssist-1
The auto-hold brakes function as follows withPilot Assist.

Auto-hold brake function
In slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, Pilot Assist will go into standby mode andthe auto-hold brake function will activate.
–The driver will then have to reactivate PilotAssist in one of the following ways:
•Press the button on the left-sidesteering wheel keypad
•Press the accelerator pedal
>Pilot Assist will resume following the vehi-cle ahead (target vehicle) if it begins tomove within approx. 6 seconds.

NOTE
Pilot Assist can keep the vehicle at a stand-still for up to 5 minutes, after which the park-ing brake will be set and Pilot Assist will gointo standby mode.
The parking brake has to be released beforePilot Assist can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivatedwhen the vehicle is at a standstill and Pilot Assistwill go into standby mode.
This means that the brakes will be released andthe vehicle can begin to roll.
The driver must actively apply the brakes to keepthe vehicle at a standstill.
This can occur in the following situations:
•the driver presses the brake pedal
•the parking brake is set
•the gear selector is moved to the P, N or Rpositions
•the driver puts Pilot Assist in standby mode

Automatically setting the parking brake
In certain situations, the parking brake is setautomatically to help keep the vehicle at a stand-still.
This occurs if:
•the driver unbuckles the seat belt or opensthe door
•Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
•the engine is turned off
•the brakes overheat

Pilot Assist-1 limitations
Pilot Assist functionality may be limited in certainsituations.
Pilot Assist is designed to help the driver in anumber of situations. However, the driver alwayshas the primary responsibility for maintaining asafe distance to other vehicles and for keepingthe vehicle in its proper traffic lane.

WARNING
Pilot Assist is not a collision avoidance sys-tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle.
Do not use Pilot Assist in demanding drivingconditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps.

•Pilot Assist does not "see" pedestrians,animals, etc.
•Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.

Steep roads and/or heavy loads
Pilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations.
Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
