CHEVROLET 2009 Silverado - Manual (Page 43)

Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight. Use the following charts to determine how much the
vehicle can weigh, based upon the vehicle model and
options.
Vehicle Axle Ratio Maximum Trailer Weight GCWR*
2WD 6.0 L V8 3.08 6,100 lbs (2 767 kg) 12,000 lbs (5 443 kg)
4WD 6.0 L V8 3.08 5,900 lbs (2 676 kg) 12,000 lbs (5 443 kg)
*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and
trailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not be
exceeded.
Trailer Brakes
If a trailer is being towed that has trailer brakes and the
trailer brakes are manually applied while driving slower
than 25 mph (40 km/h), the vehicle may go into auto
stop mode even if the brakes are not being pressed.
Using the trailer brake system manually can make the
hybrid vehicle perform as if the brake pedal in the vehicle
is being pressed. The trailer brake operation check will
still work. If the trailer brakes are manually applied for an
extended period of time, the SERVICE BRAKE SYSTEM
DIC message comes on. The message goes off after the
trailer brakes have been released. No other action is
necessary. For more information, see “Trailer Brakes” in
the Index of the vehicle’s owner manual.
