When following another vehicle, Pilot Assist can stay active below 30 km/h (20 mph).
In situations where you are driving slowly behind other vehicles, such as in a traffic queue, you may be able to activate
Pilot Assist despite driving slower than 30 km/h (20 mph). This requires a vehicle ahead whose speed your car can
match.[1]
Activation and availability
Several conditions must be met to activate Pilot Assist. They can be related to the current traffic and road conditions or the car's
system status. Some are related to the car being driving-ready, such as the driver wearing their seatbelt and all doors being
closed. Others relate to your current driving situation, such as driving at a speed within the speed range for Pilot Assist. If activ-
ation is prevented, the specific reason is typically communicated in the driver information area.
Keeping track of vehicles ahead
One of Pilot Assist's capabilities is to adapt the car's speed to a vehicle ahead and maintain a certain distance to it. Pilot Assist's
behaviour and ability to track traffic ahead depends on several factors, such as your speed and the speed of the vehicle in front.
Very slow or stationary vehicles in front of you can make Pilot Assist behave differently, depending on the situation and your
speed:
If Pilot Assist follows a vehicle that comes to a stop, Pilot Assist slows your car down to a stop behind the other vehicle.
If a stopped vehicle is detected ahead of you, Pilot Assist will slow your car down in an attempt to stop behind the other
vehicle.
Depending on your driving speed, the car may not be able to reach a full stop behind the vehicle in front. You are always
responsible for keeping track of the surrounding traffic and driving the car in a way that allows you to react and control
it safely.
When driving at high speeds, stationary vehicles in front of you can be misinterpreted by Pilot Assist, such as when
catching up to a stationary traffic queue. In a situation like this, Pilot Assist will not consider the stopped cars or slow your
car down. Always be attentive and available to control your car and brake when necessary.
Warning
Stopped or slow vehicles ahead
A stopped vehicle in your lane is a collision risk that requires you to act by braking or steering.[2]
At low speeds, Pilot Assist may pause when following another vehicle if:
there is uncertainty whether what's detected in front is a stopped vehicle or another object[3]
.
the vehicle ahead makes a turn and leaves your driving path.
you manually steer the car out of your current lane.
Car status and systems
Pilot Assist relies on the accurate detection and identification of surrounding traffic and road conditions. This includes using in-
formation from cameras, radars and other sensors. The detection system cannot handle all driving, traffic, weather or road con-
ditions. Read the separate manual sections about detection types, how they work and their limitations to better understand
how Pilot Assist's performance can be affected.
Several of Pilot Assist's features depend on other systems in the car.
