System - GMC Yukon 2015 Owner's Manual

9-64 Driving and Operating
Collision Preparation (ACP) System.
These systems can provide a boost
to braking or automatically brake the
vehicle to help avoid or lessen the
severity of crashes when driving in a
forward gear.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing
a boost to braking based on the
speed of approach and distance to
a vehicle ahead.
Minor brake pedal pulsations or
pedal movement during this time is
normal and the brake pedal should
continue to be applied as needed.
IBA will automatically disengage
only when the brake pedal is
released.
Warning
IBA may increase vehicle braking
in situations when it may not be
necessary. You could block the
Warning (Continued)
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Automatic Collision
Preparation (ACP) System
When driving in a forward gear
above 9 km/h (5 mph), ACP may
help reduce crash damage by
applying the brakes. It has a
detection range of approximately 60
m (197 ft). This front automatic
braking can only occur if a vehicle is
detected. This is shown by the FCA
vehicle ahead indicator being lit.
See Forward Collision Alert (FCA)
System on page 9-61.

Warning
ACP is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on ACP to brake the
vehicle.
ACP may not:
Respond to stopped vehicles,
pedestrians, or animals.
Detect a vehicle ahead on
winding or hilly roads.
Detect a stopped or
slow-moving vehicle or other
object ahead.
Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow. In
these situations, ACP sensor
performance is limited.
