GMC Yukon/Yukon XL/Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-17942154) - 2025
266 Driving and Operating
If y
our vehicle is equipped with Adaptive Cruise
C
ontrol (ACC), changing the FCA timing setting
automatically changes the ACC following gap
setting (Far, Medium, or Near).
Following Distance Indicator
If equipped, the following distance to
amoving vehicle ahead in your path is
indicated in following time in seconds on the
Driver Information Center (DIC). See Driver
Information Center (DIC) 3124. The minimum
following time is 0.5 seconds away. If there is no
vehicle detected ahead, or the vehicle ahead is
out of sensor range, dashes will be displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts for turning
vehicles, vehicles in other lanes, objects that
are not vehicles, or shadows. These alerts are
normal operation and the vehicle does not
need service.
Cleaning the System
If the FCA system does not seem to operate
properly, this may correct the issue:
•
Clean the outside of the windshield in front
of the rearview mirror.
•
Clean the entire front of the vehicle.
•
Cl
ean the headlamps.
For cleaning instructions, see “Washing the
Vehicle” under Exterior Care 3388.
System operation may also be limited under
snow, heavy rain, or road spray conditions.
Automatic Emergency Braking
(AEB)
If equipped, the AEB system may help avoid or
reduce the harm caused by front-end crashes.
AEB also includes Intelligent Brake Assist (IBA).
When the system detects avehicle ahead
in your path that is traveling in the same
direction that you may be about to crash
into, it can provide aboost to braking or
automatically brake the vehicle. This can help
avoid or lessen the severity of crashes when
driving in aforward gear. Depending on the
situation, the vehicle may automatically brake
moderately or hard. Always wear aseat belt
and ensure that all passengers are properly
restrained. This automatic emergency braking
can only occur if avehicle is detected. This is
shown by the FCA vehicle ahead indicator being
lit. See Forward Collision Alert (FCA) System
3264.
The system works when driving in aforward
ge
ar between 8km/h (5 mph) and 80 km/h
(50 mph), or on vehicles with Adaptive Cruise
Control (ACC), above 4km/h (2 mph). It
can detect vehicles up to approximately 60
m(197 ft).
{ Warning
A
EB is an emergency crash preparation
fe
ature and is not designed to avoid
crashes. Do not rely on AEB to brake the
vehicle. AEB will not brake outside of its
operating speed range and only responds
to detected vehicles.
AEB may not:
•
Detect avehicle ahead on winding or
hilly roads.
•
Detect all vehicles, especially vehicles
with atrailer, tractors, muddy
vehicles, etc.
•
Detect avehicle when weather limits
visibility, such as in fog, rain, or snow.
•
Detect avehicle ahead if it is partially
blocked by pedestrians or other objects.
