Gross Combined Weight (GCW) Alert
If equipped, the Gross Combined Weight
(GCW) Alert can display a message in the
Driver Information Center (DIC), indicating
that the estimated combined weight of the
vehicle and trailer may exceed the vehicle
’
s
Gross Combined Weight Rating (GCWR),
under certain circumstances. See "Gross
Combined Weight Rating" section above. The
vehicle does not actually measure the
loaded weight of your vehicle or trailer.
It uses vehicle data to estimate these
weights after you begin a trip.
The alert will not activate unless:
.
The feature is turned on in the Trailering
application, see
.
.
The vehicle-trailer combination is driven
with enough acceleration events for the
software algorithm to estimate the
combined vehicle and trailer weight
.
The estimated weight could exceed the
vehicle
’
s maximum GCWR.
If you see the alert message, stop the
vehicle when it is safe and check whether
the vehicle and trailer are overloaded using
a scale. See
“
Maximum Trailer Weight
”
later
in this section.

Warning
Always determine the actual weights of
the loaded vehicle and trailer using a
vehicle scale before beginning a trip.
Never use the GCW Alert to determine
whether the vehicle and trailer are
properly loaded or overloaded. Do not
drive with an overloaded vehicle or
trailer. Death, serious injury, or property
damage could occur.
GCWR is only one of the maximum weight
ratings applicable to your vehicle and trailer.
The GCW Alert does not estimate whether
the vehicle alone exceeds the GVWR, the
rear-axle weight exceeds GAWR-RR, the
trailer exceeds the maximum trailer weight
rating or the trailer tongue weight exceeds
the maximum trailer tongue weight rating.
Always verify that the weight of the vehicle,
vehicle contents, trailer, trailer contents and
trailer tongue are below all of these
maximum weight ratings. See "Maximum
Trailer Weight" section below.
Gross Vehicle Weight Rating (GVWR)
For information about the vehicle maximum
load capacity, see
When calculating the GVWR with a trailer
attached, the trailer tongue weight must be
included as part of the weight the vehicle is
carrying.
Maximum Trailer Weight
The maximum trailer weight rating is
calculated assuming the tow vehicle has a
driver, a front seat passenger, and all
required trailering equipment. This value
represents the heaviest trailer the vehicle
can tow, but it may be necessary to reduce
the trailer weight to stay within the GCWR,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the Trailering Information Label to
determine how much the trailer can weigh.
