Switching target vehicles with Pilot
Assist
At certain speeds, models with automatic trans-
missions and Pilot Assist can switch target vehi-
cles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be
stationary traffic ahead.
When Pilot Assist is actively following another
vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle, Pilot Assist will brake for the sta-
tionary vehicle.

WARNING
When Pilot Assist follows another vehicle at
speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi-
cle to a stationary one – Pilot Assist will
ignore the stationary vehicle and instead
accelerate to the stored speed.
•
The driver must then intervene and apply
the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby
mode if:
•
your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the target object is a stationary vehicle or
another object, e.g. a speed bump.
•
your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.

Automatic braking with Pilot Assist
Pilot Assist has a special braking function in
slow traffic and at a standstill.
Braking function in slow traffic and at a
standstill
In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Pilot Assist will go into standby mode and the
Auto-hold brake function will activate.
Pilot Assist can be reactivated by:
–
•
Pressing the
button on the steering
wheel keypad.
•
Pressing the accelerator pedal.
> Pilot Assist will resume following the vehi-
cle ahead if it begins to move within
approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationary
for no more than 5 minutes – after that time
the parking brake is applied and the function
is deactivated.
The parking brake must be released before
Pilot Assist can be reactivated.
