Chevrolet Silverado 2500 HD 2024 Owner's Manual page 273

The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before towing a
trailer.
When towing a trailer:
Become familiar with, and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
State laws may require the use of
extended side view mirrors. If your
visibility is limited or restricted while
towing, install extended side view mirrors
on your vehicle, even if not required.
Do not tow a trailer during the first
800 km (500 mi) of vehicle use to prevent
damage to the engine, axle, or other
parts.
Perform the first oil change before heavy
towing.
Do not drive over 80 km/h (50 mph) and
do not make starts at full throttle during
the first 800 km (500 mi) of trailer
towing.
Tow in D (Drive). Tow/Haul Mode is
recommended for heavier trailers. See
Tow/Haul Mode 0 221. If the transmission
downshifts too often, a lower gear may
be selected using Manual Mode. See
Manual Mode 0 220.
The following advanced driver assistance
features should be turned off when towing
a trailer, and may turn off automatically
when a trailer is detected:
Park Assist
Reverse Automatic Braking (RAB)
Rear Cross Traffic Alert (RCTA)
Rear Cross Traffic Braking (RCTB)
Lane Change Alert (LCA)
Super Cruise and Adaptive Cruise Control
(ACC), unless equipped with trailering
functionality, see Adaptive Cruise Control
(Camera) 0 235.
Automatic Emergency Braking (AEB) and
Front Pedestrian Braking (FPB) should be set
to Alert unless equipped with Super Cruise.
Do not use Automatic Parking Assist (APA)
while towing a trailer.

trailer:
Driving and Operating
Warning (Continued)
Do not drive with the liftgate, trunk/
hatch, or rear-most window open.
Fully open the air outlets on or under
the instrument panel.
Adjust the climate control system to a
setting that brings in only outside air.
See Climate Control Systems in the
Index.
For more information about carbon
monoxide, see Engine Exhaust 0 217.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Get used to the handling and braking
of the combination by driving on a level
road surface before driving on public roads.
The trailer structure, the tires, and the
brakes must all be rated to carry the
intended cargo. Inadequate trailer
equipment can cause the combination to
operate in an unexpected or unsafe manner.
Before driving, inspect all trailer hitch parts
and attachments, safety chains, electrical
connectors, lamps, tires, and mirrors. See
Towing Equipment 0 278. If the trailer has
