the GCWR for your vehicle. The GCWR for
the vehicle is on the Trailering Information
Label.
To check that the weight of the vehicle and
trailer are within the GCWR for the vehicle,
follow these steps:
1. Start with the "curb weight" from the
Trailering Information Label.
2. Add the weight of the trailer loaded with
cargo and ready for the trip.
3. Add the weight of all passengers.
4. Add the weight of all cargo in the
vehicle.
5. Add the weight of hitch hardware such
as a draw bar, ball, load equalizer bars,
or sway bars.
6. Add the weight of any accessories or
aftermarket equipment added to the
vehicle.
The resulting weight cannot exceed the
GCWR value on the Trailering Information
Label.
The GCWR can also be confirmed by
weighing the truck and trailer on a public
scale. The truck and trailer should be loaded
for the trip with passengers and cargo.
Gross Combined Weight (GCW) Alert
If equipped, the 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 GCWR, under
certain circumstances. See Gross Combined
Weight Rating 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 Trailering App 0 318.
The vehicle-trailer combination have been
used enough together for the software to
estimate the combined vehicle and trailer
weight.
The estimated weight could exceed the
vehicle s maximum GCWR.
If the GCW alert message is displayed, stop
the vehicle when it is safe and check the
vehicle and trailer weight using a scale. See
Maximum Trailer Weight below.
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
