Starting and activating Pilot Assist

The Pilot Assist feature helps keep the vehicle in its current traffic lane, at a set speed and a set time interval to the vehicle ahead.

Prerequisites

The prerequisites for activating Pilot Assist are:
  • The vehicle ahead must be within a reasonable (detectable) distance
  • The camera must be able to clearly detect the traffic lane's side marker lines
  • The vehicle's speed must be under approx. 30 mph (50 km/h).
P5-1507-ACC QA Symbol

A WHITE symbol indicates that Pilot Assist has been selected.

In other cases, the WHITE arrow pointing to the right indicates that the system is available.

A YELLOW symbol with a flashing WHITE arrow indicates that the system is about to shift into standby mode.

With ACC in standby mode:
Tap ▶ (4).
The symbol will be displayed and Pilot Assist will go into standby mode.
Press the P5-1507-Symbol 5x3,5-CC rattknapp Centrum-V button (1) on the left-side steering wheel keypad.
Pilot Assist will go into active mode.

 Warning

  • Pilot Assist is not a collision avoidance system. The driver is always responsible for applying the brakes if the system does not detect another vehicle.
  • Do not use Pilot Assist in demanding driving conditions such as city driving or other heavy traffic situations, in slippery conditions, when there is a great deal of water or slush on the road, during heavy rain or snow, in poor visibility, on winding roads or on highway on- or off-ramps.
  • Pilot Assist uses the vehicle's camera and radar sensor, which have limitations.

Pilot Assist may deactivate or not function optimally if:

  • 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 with another, at exits or if there are many road signs/markers.
  • if there are edges or other lines on or near the lane, e.g., curbs, cracks, repaired areas, sharp shadows, etc.
  • the lane is narrow or winding.
  • the weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).

The driver should also be aware that Pilot Assist has the following limitations:

  • High curbs, barriers and temporary obstacles (cones, barriers etc) may not be detected or could be detected incorrectly as side marker lines, which may create a risk of collision. The driver must ensure a safe distance to these obstacles.
  • The camera or radar sensor may not be able to detect objects if there are potholes or if there are stationary objects partially or completely blocking the road.
  • Pilot Assist does not "see" pedestrians, animals, etc.
  • Pilot Assist's steering capacity is limited and may not always be able to help the driver keep the vehicle in the lane.

Hands on the steering wheel

Pilot Assist only functions when the driver's hands are on the steering wheel, which is continuously monitored by the system. If this is not the case, the driver will be alerted by a text message in the instrument panel. If the driver's hands are not returned to the steering wheel, an audible signal will sound.

If the driver does not return his/her hands to the steering wheel after the audible signal, Pilot Assist will go into standby mode and must be reactivated by pressing P5-1507-Symbol 5x3,5-CC rattknapp Centrum-V.
