224 Driving and Operating
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
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 pulling a
trailer.
Trailer Weight
{Warning
Never exceed the towing capacity for
your vehicle.
Safe trailering requires monitoring the
weight, speed, altitude, road grades, outside
temperature, and how frequently the vehicle
is used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle,
including:
.GCWR: Gross Combined Weight Rating
.GVWR: Gross Vehicle Weight Rating
.Maximum Trailer Weight Rating
.GAWR-RR: Gross Axle Weight Rating-Rear
.Maximum Trailer Tongue Weight Rating
See “Weight-Distributing Hitch Adjustment”
under Towing Equipment 0228 to
determine if equalizer bars are required to
obtain the maximum trailer weight rating.
See “Trailer Brakes” underTowing
Equipment 0228 to determine if brakes are
required based on your trailer's weight.
The only way to be sure the weight is not
exceeding any of these ratings is to weigh
the tow vehicle and trailer combination,
fully loaded for the trip, getting individual
weights for each of these items.
{Warning
You and others could be seriously injured
or killed if the trailer is too heavy or the
trailer brakes are inadequate for the load.
The vehicle may be damaged, and the
repairs would not be covered by the
vehicle warranty.
Only tow a trailer if all the steps in this
section have been followed. Ask your
dealer for advice and information about
towing a trailer.
Gross Combined Weight Rating (GCWR)
GCWR is the total allowable weight of the
completely loaded vehicle and trailer
including any fuel, passengers, cargo,
equipment, and accessories. Do not exceed
the GCWR for your vehicle. The GCWR for
the vehicle is on the Tow Rating Chart
following.
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.

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15274222) - 2022 - CRC - 11/2/21
Driving and Operating 225
2. Add the weight of the trailer loaded withcargo 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 for the vehicle.
The gross combined weight 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 Vehicle Weight Rating (GVWR)
For information about the vehicle's
maximum load capacity, see Vehicle Load
Limits 0178. 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 tow rating chart to determine how
much the trailer can weigh, based on the
vehicle model, powertrain and trailering
options.
Weights listed apply for conventional trailers
unless otherwise noted.

(a) 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.
(*) Valid only for vehicles with Z82 trailering package. If the vehicle has a bumper mounted hitch then the maximum trailer weight is limited
to 1 587 kg (3,500 lb) and GCWR is limited to 3 856 kg (8,500 lb).
A step bumper trailer hitch can only support
a total trailer weight up to 2 271 kg (5,000
lb). If a trailer hitch ball is added to the step
bumper, check the hitch ball rating to be
sure it is higher than the total trailer
weight.
Maximum Trailer Tongue Weight Rating
The Maximum Trailer Tongue Weight Rating
is the allowable trailer tongue weight that
the vehicle can support using a conventional
trailer hitch. It may be necessary to reduce
the overall trailer weight to stay within the
maximum trailer tongue weight rating while
still maintaining the correct trailer load
balance.

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15274222) - 2022 - CRC - 11/2/21
Driving and Operating 227
Do not exceed a maximum trailer tongue
weight of 349 (770 lb).
The trailer tongue weight contributes to the
Gross Vehicle Weight (GVW). GVW includes
the curb weight of your vehicle, any
passengers, cargo, equipment, and the trailer
tongue weight. Vehicle options, passengers,
cargo, and equipment reduce the maximum
allowable tongue weight the vehicle can
carry, which also reduces the maximum
allowable trailer weight.
Trailer Load Balance
The correct trailer load balance must be
maintained to ensure trailer stability.
Incorrect load balance is a leading cause of
trailer sway.
The trailer tongue weight (1) should be 10–
15% of the total loaded trailer weight (2).
Some specific trailer types, such as boat
trailers, fall outside of this range. Always
refer to the trailer owner’s manual for the
recommended trailer tongue weight for each
trailer. Never exceed the maximum loads for
the vehicle, hitch and trailer.
After loading the trailer, separately weigh
the trailer and then the trailer tongue and
calculate the trailer load balance percentage
to see if the weights and distribution are
appropriate for your vehicle. If the trailer
weight is too high, it may be possible to
transfer some of the cargo into your vehicle.If the trailer tongue weight is too high or
too low, it may be possible to rearrange
some of the cargo inside of the trailer.
Do not exceed the maximum allowable
tongue weight for your vehicle. Use the
shortest hitch extension available to position
the hitch ball closer to your vehicle. This will
help reduce the effect of the trailer tongue
weight on the trailer hitch and the rear axle.
If a cargo carrier is used in the trailer hitch
receiver, choose a carrier that positions the
load as close to the vehicle as possible.
Make sure the total weight, including the
carrier, is no more than half of the
maximum allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever is less.
Rear Gross Axle Weight Rating
(GAWR-RR)
The GAWR-RR is the total weight that can be
supported by the rear axle of the vehicle. Do
not exceed the GAWR-RR for the vehicle,
with the tow vehicle and trailer fully loaded
for the trip including the weight of the
trailer tongue. If using a weight-distributing
hitch, do not exceed the GAWR-RR before
applying the weight distribution spring bars.
Ask your dealer for trailering information or
assistance.

15274222) - 2022 - CRC - 11/2/21
228 Driving and Operating
Towing Equipment
Hitches
Always use the correct hitch equipment for
your vehicle. Crosswinds, large trucks going
by, and rough roads can affect the trailer
and the hitch.
Proper hitch equipment for your vehicle
helps maintain control of the vehicle-trailer
combination. Many trailers can be towed
using a weight-carrying hitch which has a
coupler latched to the hitch ball, or a tow
eye latched to a pintle hook. Other trailers
may require a weight-distributing hitch that
uses spring bars to distribute the trailer
tongue weight between your vehicle and
trailer axles. See“Maximum Trailer Tongue
Weight” underTrailer Towing 0223 for
weight limits with various hitch types.
Avoid sharp turns when using a step-bumper
hitch to prevent damage. Make wider turns
to prevent contact between your trailer and
your bumper.
Consider using mechanical sway controls
with any trailer. Ask a trailering professional
about sway controls or refer to the trailer
manufacturer's recommendations and
instructions.
Weight-Distributing Hitch and
Adjustment
A weight-distributing hitch may be useful
with some trailers.
1. Front of Vehicle
2. Body to Ground Distance
When using a weight-distributing hitch,
measure the front fender height distance (2)
before connecting the trailer. Adjust the
spring bars until the front fender height
distance (2) is the same height before the
trailer was connected. Do not reduce the
front fender height below the initial
distance (2).
Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
.Tires must be properly inflated to support
loads while towing a trailer. See Tires
0 269 for instructions on proper tire
inflation.
Safety Chains
Always attach chains between the vehicle
and the trailer, and attach the chains to the
holes on the trailer hitch platform.
Instructions about safety chains may be
provided by the hitch manufacturer or by
the trailer manufacturer.
Cross the safety chains under the tongue of
the trailer to help prevent the tongue from
contacting the road if it becomes separated
from the hitch. Always leave just enough
slack so the combination can turn. Never
allow safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 900 kg (2,000 lb) must
be equipped with brake systems and with
brakes for each axle. Trailer braking
equipment conforming to Canadian

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15274222) - 2022 - CRC - 11/2/21
Driving and Operating 229
Standards Association (CSA) requirement
CAN3-D313, or its equivalent, is
recommended.
State or local regulations may require
trailers to have their own braking system if
the loaded weight of the trailer exceeds
certain minimums that can vary from state
to state. Read and follow the instructions for
the trailer brakes so they are installed,
adjusted, and maintained properly. Never
attempt to tap into your vehicle's hydraulic
brake system. If you do, both the vehicle
anti-lock brakes and the trailer brakes may
not function, which could result in a crash.
Trailer Wiring Harness
For vehicles not equipped with heavy-duty
trailering, a harness is secured underneath
the left side of the vehicle, next to the spare
tire. The harness requires the installation of
a trailer connector, which is available
through your dealer. The seven-wire harness
contains the following trailer circuits:
.Yellow: Left stop/turn signal
.Green: Right stop/turn signal
.Brown: Taillamps/parking lamps
.Black: Ground
.Gray: Back-up lamps
.Orange: Battery feed
.Blue: Trailer brake
To help charge a remote (non-vehicle)
battery, press the Tow/Haul Mode button
on the center stack. If the trailer is too light
for Tow/Haul Mode, turn on the headlamps
to help charge the battery.
Trailer Brake Control Wiring Harness
A four-wire harness, without connector, is
secured behind the left side kick panel. The
harness contains the following circuits:
.Red/Green: Battery feed
.Black: Ground
.White/Blue: Brake signal to controller
.Blue: Trailer Brake power to trailer
connector To remove the left side kick panel, start at
the front of the panel pulling toward the
rear of the vehicle and lift upward to
disengage the integral clips.
Turn Signals When Towing a Trailer
When properly connected, the trailer turn
signals will illuminate to indicate the vehicle
is turning, changing lanes, or stopping.
When towing a trailer, the arrows on the
instrument cluster will illuminate even if the
trailer is not properly connected or the bulbs
are burned out.
Tow/Haul Mode
For instructions on how to enter Tow/Haul
Mode, see
Tow/Haul Mode 0194.
Tow/Haul assists when pulling a heavy
trailer or a large or heavy load.
Tow/Haul Mode is designed to be most
effective when the vehicle and trailer
combined weight is at least 75% of the
vehicle's Gross Combined Weight Rating
(GCWR). See “Weight of the Trailer” under
Trailer Towing 0223.
Tow/Haul Mode is most useful when towing
a heavy trailer or carrying a large or
heavy load:
.through rolling terrain.

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15274222) - 2022 - CRC - 11/2/21
230 Driving and Operating
.in stop-and-go traffic.
.in busy parking lots.
Operating the vehicle in Tow/Haul Mode
when lightly loaded or not towing will not
cause damage; however, it is not
recommended and may result in unpleasant
engine and transmission driving
characteristics and reduced fuel economy.
Integrated Trailer Brake Control System
The vehicle may have an Integrated Trailer
Brake Control (ITBC) system for use with
electric trailer brakes or most electric over
hydraulic trailer brake systems. These
instructions apply to both types of electric
trailer brakes.
This symbol is on the Trailer Brake Control
Panel on vehicles with an ITBC system. The
power output to the trailer brakes is
proportional to the amount of vehicle
braking. This available power output to the
trailer brakes can be adjusted to a wide
range of trailering situations. The ITBC system is integrated with the
vehicle’s brake, antilock brake, and
StabiliTrak/Electronic Stability Control (ESC)
systems. In trailering conditions that cause
the vehicle’s antilock brake or StabiliTrak/
ESC systems to activate, power sent to the
trailer's brakes will be automatically
adjusted to minimize trailer wheel lock-up.
This does not imply that the trailer has
StabiliTrak/ESC.
If the vehicle’s brake, anti-lock brake,
or StabiliTrak/ESC systems are not
functioning properly, the ITBC system may
not function fully or at all. Make sure all of
these systems are fully operational to allow
the ITBC system to function properly.
The ITBC system is powered through the
vehicle's electrical system. Turning the
ignition off will also turn off the ITBC
system. The ITBC system is fully functional
only when the ignition is in ON/RUN.{Warning
Connecting a trailer that has an air brake
system may result in reduced or
complete loss of trailer braking, including
increased stopping distance or trailer
instability which could result in serious
(Continued)
Warning (Continued)
injury, death, or property damage. Only
use the ITBC system with electric or
electric over hydraulic trailer brake
systems.

brakes. Use this lever to adjust Trailer Gain
to achieve proper power output to the
trailer brakes. The trailer's and the vehicle's brake lamps will come on when either
vehicle brakes or manual trailer brakes are
applied and properly connected.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for a specific
trailering condition and it must be
readjusted anytime vehicle loading, trailer
loading, or road surface conditions change.
{Warning
Trailer brakes that are over-gained or
under-gained may not stop the vehicle
and the trailer as intended and can result
in a crash. Always follow the instructions
to set the Trailer Gain for the proper
trailer stopping performance.
To adjust Trailer Gain for each towing
condition: 1. Drive the vehicle with the trailer attached on a level road surface
representative of the towing condition
and free of traffic at about 32–40 km/h
(20–25 mph) and fully apply the Manual
Trailer Brake Apply Lever.
Adjusting Trailer Gain at speeds lower
than 32–40 km/h (20–25 mph) may
result in an incorrect gain setting.
