time interval to the vehicle ahead does not
allow an increase in speed.
•
The higher the speed, the greater the dis-
tance to the vehicle ahead for a given time
interval.
•
Only use time intervals permitted by local
traffic regulations.
WARNING
•
Only use a time interval that is suitable in
current traffic conditions.
•
A short time interval gives the driver lim-
ited reaction time if an unexpected situa-
tion occurs in traffic.

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.
Function
The vehicle's camera monitors the traffic lane's
side marker lines and a distance monitor helps
maintain the set time interval to the vehicle
ahead.
Pilot Assist helps provide more relaxed driving in
heavy, slow-moving traffic at speeds up to
30 mph (50 km/h) on highways and major roads.
Function overview
Windshield module containing the camera/
radar sensor
Monitoring distance
Monitoring side marker lines
DRIVER SUPPORT
The driver sets the desired time interval to the
vehicle ahead. Pilot Assist monitors that vehicle
and the traffic lane's side market lines using the
camera and radar sensor mounted in the upper,
center section of the windshield. It helps maintain
the set time interval by automatically adjusting
speed and by providing steering assistance to
help keep your vehicle in the lane.
Pilot Assist's steering assistance is based on
monitoring the direction of the vehicle ahead and
the traffic lane's side marker lines. The driver can
always override Pilot Assist and steer the vehicle
to e.g., change lanes, etc.
If the camera and radar sensor cannot detect the
lane's side marker lines or a vehicle ahead, Pilot
Assist goes into standby mode.
When Pilot Assist is in standby mode and your
vehicle comes too close to the vehicle ahead, the
driver will be alerted by the Distance Alert func-
tion.
