Warning (Continued)
.The plug must be plugged into an
appropriate electrical outlet that is
properly installed in accordance with
all local codes and ordinances. Do not
modify the plug provided with the
product. If the plug does not fit the
electrical outlet, have a proper
electrical outlet installed by a qualified
electrician. If ground is missing, the
charge cord indicators will indicate an
electrical system fault and the vehicle
may not charge.
Installing and Operating the Portable
Charge Cord
The charge cord must be on a dedicated
individual branch circuit. A dedicated circuit
ensures that there is enough power
available without overloading the system.
If a dedicated circuit is not used, the circuit
breaker could trip or open. If a dedicated
circuit is not available, contact a a qualified
electrician. See“Grounding Instructions”
later on in this section. 1. Snap the desired connectors into the
control box before making any other
connections.
Ensure the connectors are fully inserted
into the control box or the charge cord
will not work properly.
2. Mount the charge cord to reduce strainon the electrical outlet/plug. Mount the
control box in a suitable location to
prevent physical stress on the electrical
outlets and charge cord components.
Mount the control box directly to the
wall or stud near a suitable electrical
outlet. The retention eyelets on the
control box are optimized for use with
#10 drywall screws.

the charging. If this error continues, stop
charging your vehicle. See your dealer for
service.
Charge Level Selection
Charge level selection can be made using
the Charging tab in the Energy Application
on the infotainment display. For instructions
to set cord limit settings for a charge
session, seeCharging0123.
{Warning
Using a charge level that exceeds the
electrical circuit or electrical outlet
capacity may start a fire or damage the
electrical circuit. Use the lowest charge
level until a qualified electrician inspects
the electrical circuit capacity. Use the
lowest charge level if the electrical circuit
or electrical outlet capacity is not known.
Troubleshooting
Disconnect the charge cord from the vehicle
and confirm that the attachment plug is not
too hot to grasp before removing. If it is not hot, manually reboot the charge
cord by unplugging and re-plugging the
attachment plug into the electrical outlet.
If the same fault reoccurs, test the charge
cord with a different electrical outlet.
The charge cord monitors temperature at
several locations and may reduce charging
power or interrupt charging if temperatures
become too high. The charge cord status
indicators illuminate and identify this fault.
In hot climates, move the charge cord away
from direct sunlight and/or hot surfaces
such as asphalt paving for approximately
30 minutes.
If there are signs of melting or scorching, do
not touch the charge cord or attachment
plug. Have a qualified electrician inspect and
repair the issue.
If there are no signs of damage, check how
firm the fit of the plug is. If the plug easily
pulls away from the electrical outlet, test
the plug on a known good electrical outlet.
If the fault condition returns, have your
charge cord inspected by your dealership.
If the fault does not return, stop using the
suspected circuit and have a qualified
electrician inspect and repair the issue.
Grounding Instructions
The charge circuit must be grounded. If the
charge circuit should malfunction or break
down, grounding provides a path of least
resistance for the electric current to reduce
the risk of electric shock. This product is
equipped with a cord that has an equipment
grounding conductor and a grounding plug.
The plug must be plugged into an
appropriate outlet that is properly installed
and grounded in accordance with all local
codes and ordinances.
{Warning
Improper connection of the charge cord
ground may cause electrical shock. Check
with a qualified electrician if there is
doubt as to whether the charge circuit is
properly grounded. Do not modify the
plug provided with the product. If it will
not fit the electrical outlet, have a proper
electrical outlet installed by a qualified
electrician.

Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a
trailer if the correct equipment is not
used or the vehicle is not driven properly.
For example, if the trailer is too heavy or
the trailer brakes are inadequate for the
load, the vehicle may not stop as
expected. You and others could be
seriously injured. The vehicle may also be
damaged, and the repairs would not be
covered by the vehicle warranty. Pull a
trailer only if all the steps in this section
have been followed. Ask your dealer for
advice and information about towing a
trailer with the vehicle.
Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering affects handling,
acceleration, braking, and durability.
Successful and safe trailering requires proper
use of the correct equipment.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 vehicle.
.Do not drive over 800 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
Driver Mode Control
0209.
.One-Pedal Driving can be a useful feature
when towing. See One-Pedal Driving
0 203. 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
(Advanced) 0217.
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.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Become familiar with handling and
braking of the combination by driving on a
level road surface before driving on public
roads.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/17/23
Driving and Operating 295
The trailer structure, the tires, and the
brakes must be 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 Equipment0301. If the trailer has
electric brakes, start the combination
moving and then manually apply the trailer
brake controller to check the trailer brakes
work. During the trip, occasionally check
that the cargo and trailer are secure and
that the lamps and any trailer brakes are
working.
Towing with a Stability Control System
When towing, the stability control system
might be heard. The system reacts to
vehicle movement caused by the trailer,
which mainly occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving without a
trailer to help to avoid heavy braking and
sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination of the
vehicle and trailer will not accelerate as
quickly and is much longer than the vehicle
alone. It is necessary to go much farther
beyond the passed vehicle before returning
to the lane. Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel with
one hand. To move the trailer to the left,
move that hand to the left. To move the
trailer to the right, move that hand to the
right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Caution
Turn more slowly and make wider arcs
when towing a trailer to prevent damage
to your vehicle. Making very sharp turns
could cause the trailer to contact the
vehicle. Make wider turns than normal when towing,
so the trailer does not go over soft
shoulders, over curbs, or strike road signs,
trees, or other objects. Always signal turns
well in advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed before starting down a long or
steep downhill grade. Use regenerative
braking to help slow the vehicle or maintain
speed by keeping the vehicle in gear and
limiting the initial battery charge to 80% or
less. Avoid using Regen on Demand. See
Hill
and Mountain Roads 0190.
Viewing Systems
If equipped, the viewing systems on the
vehicle can improve visibility while hitching,
backing up, and driving with a trailer. See
Advanced Driver Assistance Systems 0244.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer on a
level surface when possible.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/17/23
296 Driving and Operating
When parking your vehicle and trailer on
a hill:1. Press and hold the brake pedal, but do not shift into P (Park). Turn the wheels
toward the curb if facing downhill or
toward traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake pedal to
allow the chocks to absorb the load of
the trailer.
4. Reapply the brake pedal. Then apply the electric parking brake and shift into
P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the vehicle.
.Shift into the desired gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Launching and Retrieving a Boat
Backing the Trailer into the Water
{Warning
.Have all passengers get out of the
vehicle before backing onto the sloped
part of the ramp. Lower the driver and
passenger side windows before
backing onto the ramp. This will
provide a means of escape in the
unlikely event the vehicle slides into
the water.
.If the boat launch surface is slippery,
have the driver remain in the vehicle
with the brake pedal applied while the
boat is being launched. The boat
launch can be especially slippery at
low tide when part of the ramp was
previously submerged at high tide. Do
not back onto the ramp to launch the
boat if you are not sure the vehicle
can maintain traction.
.Do not move the vehicle if someone is
in the path of the trailer. Some parts
of the trailer might be underwater and
not visible to people who are assisting
in launching the boat. Disconnect the trailer wiring before backing
the trailer into the water to prevent damage
to the electrical circuits. Reconnect the
wiring to the trailer after removing the
trailer from the water. If the trailer has
electric brakes that can function when the
trailer is submerged, it might help to leave
the electrical trailer connector attached to
maintain trailer brake functionality while on
the boat ramp.
To back the trailer into the water:
1. Slowly back down the boat ramp until the boat is floating, but no further than
necessary.
2. Press and hold the brake pedal, but do not shift into P (Park).
3. Have someone place chocks under the front wheels of the vehicle.
4. Gradually release the brake pedal to allow the chocks to absorb the load of
the trailer.
5. Reapply the brake pedal. Then apply the parking brake and shift into P (Park).
6. Release the brake pedal.

Driving and Operating 297
Pulling the Trailer from the Water1. Press and hold the brake pedal.
2. Start the vehicle and shift into D (Drive) or L (Low).
3. Release the parking brake.
4. Let up on the brake pedal.
5. Drive slowly until the tires are clear of the chocks.
6. Stop and have someone pick up and store the chocks.
7. Slowly pull the trailer from the water.
Caution
If the vehicle tires begin to spin and the
vehicle begins to slide toward the water,
remove your foot from the accelerator
pedal and apply the brake pedal. Seek
help to have the vehicle towed up
the ramp.
Maintenance when Trailer Towing
The vehicle needs service more often when
used to tow trailers. See Maintenance
Schedule 0389. It is especially important to
check the cooling system and brake system
before and during each trip. Check periodically that all nuts and bolts on
the trailer hitch are tight.
Trailer Towing
Caution
Towing a trailer improperly can damage
the vehicle and result in costly repairs
not covered by the vehicle warranty. To
tow a trailer correctly, follow the
directions in this section and see your
dealer for important information about
towing a trailer with the vehicle.
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, and
durability. 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:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Maximum Trailer Tongue Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
See “Weight-Distributing Hitch and
Adjustment” underTowing Equipment 0301
to determine if equalizer bars are required
to obtain the maximum trailer weight
rating.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/17/23
298 Driving and Operating
See“Trailer Brakes” underTowing
Equipment 0301 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.
A trailering information label on the center
pillar (B-pillar) shows tow rating information
for the vehicle.
{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 (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" later in this
section. 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 App0310.
.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 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
on 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 Gross Vehicle
Weight Rating (GVWR), the rear-axle weight
exceeds Gross Axle Weight Rating
(GAWR-RR), the trailer exceeds the Maximum
Trailer Weight Rating or the trailer tongue
weight exceeds the Maximum 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" below.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/17/23
Driving and Operating 301
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.
The GAWR-RR for the vehicle is on the
Trailering Information Label.
For additional assistance with trailering or
additional information, see your dealer.
Towing Equipment
Hitches
{Warning
In order to avoid serious injury or
property damage, always follow the hitch
manufacturer's instructions when securing
your draw bar/coupling device to the
vehicle's hitch receiver.
Ensure that the draw bar/coupling device
is secured with a locking retainer pin or
other means such that rotation of the pin
or locking mechanism will not cause the
pin to back out or loosen during use.
Failure to correctly secure the draw bar/
coupling device to the receiver can result
in separation of the hitch/receiver while
towing.
Conventional Hitch
A conventional hitch is bolted to the frame
or cross member of the tow vehicle, and is
generally rated Class 2, 3, or 4.
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 with 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
Rating” underTrailer Towing 0297 for
weight limits with various hitch types.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not attach to
the 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. Use the following
guidelines to determine if a
weight-distributing hitch should be used.
