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 (Continued)
Warning (Continued)
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.
2. Adjust the Trailer Gain, using the Trailer Gain adjustment buttons, to just below
the point of trailer wheel lockup,
indicated by trailer wheel squeal or tire
smoke when a trailer wheel locks. Trailer
wheel lockup may not occur if towing a
heavily loaded trailer. In this case, adjust
the Trailer Gain to the highest allowable
setting for the towing condition.

5. Windshield Washer Fluid Reservoir. See Washer Fluid 0328.
Cooling System
It is not necessary to regularly check coolant
unless a leak is suspected or an unusual
noise is heard. A coolant loss could indicate
a problem. Have it inspected and repaired
by your dealer.
The following explains the cooling system
and how to check coolant level.
During vehicle operation and also during
charging, the high voltage battery cells in
the vehicle are kept within a normal
operating temperature range. If the
temperature rises above this temperature, the battery cooling system turns on the air
conditioning compressor and cools the
coolant until the correct temperature is
reached. If the temperature falls below this
temperature, a high voltage heater, located
outside the battery on a cradle, heats the
coolant until the correct temperature is
reached.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See
Maintenance
Schedule 0389.
The coolant reservoir is in the underhood
compartment. See Underhood Compartment
Overview 0325.
To access the coolant reservoir under the
hood, the right side access cover needs to
be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood019.
3. Turn the three bolts three quarter turn
and remove the right side access cover.

336 Vehicle Care
Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in the underhoodcompartment fuse block.
3. Use the fuse puller to remove the fusefrom the top or side, as shown above. 4. If the fuse must be replaced
immediately, borrow a replacement fuse
with the same amperage from the fuse
block. Choose a vehicle feature that is
not needed to safely operate the vehicle.
Repeat Steps 2–3.
5. Insert the replacement fuse into the empty slot of the blown fuse.
At the next opportunity, see your dealer to
replace the blown fuse.
Headlamp Wiring
An electrical overload may cause the lamps
to go on and off, or in some cases to
remain off. Have the headlamp wiring
checked right away if the lamps go on and
off or remain off.
Windshield Wipers
If the wiper motor overheats due to heavy
snow or ice, the windshield wipers will stop
until the motor cools and will then restart.
Although the circuit is protected from
electrical overload, overload due to heavy
snow or ice may cause wiper linkage
damage. Always clear ice and heavy snow
from the windshield before using the
windshield wipers.

Chevrolet Silverado EV Owner Manual (GMNA-Localizing-U.S./Canada-
16702912) - 2024 - CRC - 1/13/23
Vehicle Care 337
If the overload is caused by an electrical
problem and not snow or ice, be sure to get
it fixed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit breakers.
This greatly reduces the chance of damage
caused by electrical problems.
{Danger
Fuses and circuit breakers are marked
with their ampere rating. Do not exceed
the specified amperage rating when
replacing fuses and circuit breakers. Use
of an oversized fuse or circuit breaker can
result in a vehicle fire. You and others
could be seriously injured or killed.
{Warning
Installation or use of fuses that do not
meet GM’s original fuse specifications is
dangerous. The fuses could fail, and result
in a fire. You or others could be injured
or killed, and the vehicle could be
damaged.
See Accessories and Modifications 0324 and
General Information 0324.
To check or replace a blown fuse, see
Electrical System Overload 0335.
Underhood Compartment Fuse
Block
The underhood compartment fuse block is in
the underhood compartment, on the
passenger side of the vehicle.
Press the clips on the sides and lift the
cover to access the fuse block.
Caution
Spilling liquid on any electrical
component on the vehicle may damage
it. Always keep the covers on any
electrical component.
A fuse puller is available in the left
instrument panel end cap.
The vehicle may not be equipped with all of
the fuses, relays, and features shown.
