alarm if it has been activated:
.PressKon the RKE transmitter.
.Start the vehicle.
To avoid setting off the alarm by accident:
.Lock the vehicle after all occupants have
left the vehicle and all doors are closed.
.Always unlock a door with the RKE
transmitter.
Unlocking the driver door with the key will
not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, and
allowed to complete an event
(approximately one minute), a message will
appear on the Driver Information Center
(DIC) the next time the vehicle is started.
Theft Alarm Notification

The vehicle may have two accessory power
outlets on the instrument panel.
Remove the cover to access and replace
when not in use.
Certain power accessory plugs may not be
compatible to the accessory power outlet
and could overload vehicle or adapter fuses.
If a problem is experienced, see your dealer.
{Warning
Power is always supplied to the outlets.
Do not leave electrical equipment
plugged in when the vehicle is not in use
because the vehicle could catch fire and
cause injury or death.
Caution
Leaving electrical equipment plugged in
for an extended period of time while the
vehicle is off will drain the battery.
Always unplug electrical equipment when
not in use and do not plug in equipment
that exceeds the maximum 20 amp
rating.
When adding electrical equipment, be sure
to follow the proper installation instructions
included with the equipment. See Add-On
Electrical Equipment 0176.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty. The
power outlets are designed for accessory
power plugs only, such as cell phone
charge cords.
Power Outlet 110/120 Volt Alternating
Current
This power outlet can be used to plug in
electrical equipment that uses a maximum
limit of 150 watts.

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583525) - 2021 - CRC - 12/9/20
70 Instruments and Controls
The 110/120 volt power outlet is on the
instrument panel.
An indicator light on the outlet turns on to
show it is in use. The light comes on when
the ignition is on, equipment requiring less
than 150 watts is plugged into the outlet,
and no system fault is detected.
The indicator light does not come on when
the ignition is off, or if the equipment is not
fully seated into the outlet.
If equipment is connected using more than
150 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light turns off. To reset
the circuit, unplug the item and plug it back
in or turn the Retained Accessory Power
(RAP) off and then back on. SeeRetained
Accessory Power (RAP) 0138.
The power outlet is not designed for the
following, and may not work properly if
they are plugged in:
.Equipment with high initial peak wattage,
such as compressor-driven refrigerators
and electric power tools
.Other equipment requiring an extremely
stable power supply, such as
microcomputer-controlled electric blankets
and touch sensor lamps
.Medical equipment
Cigarette Lighter
If equipped with a cigarette lighter, to heat,
push it in all the way and let go. When it is
ready for use, it will pop back out by itself.
Do not use the lighter to plug in accessory
devices. Use the power outlets provided.
Caution
Holding a cigarette lighter in while it is
heating does not let the lighter back
away from the heating element when it
is hot. Damage from overheating can
occur to the lighter or heating element,
or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Ashtrays
If equipped with a removable ashtray, it can
be placed into the front floor console
cupholder. Open the cover to use.
Caution
If papers, pins, or other flammable items
are put in the ashtray, hot cigarettes or
other smoking materials could ignite
them and possibly damage the vehicle.
Never put flammable items in the
ashtray.
Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that
something is wrong before it becomes
serious enough to cause an expensive repair
or replacement. Paying attention to the
warning lights and gauges could prevent
injury.
Some warning lights come on briefly when
the engine is started to indicate they are
working. When one of the warning lights
comes on and stays on while driving,
or when one of the gauges shows there
may be a problem, check the section that
explains what to do. Waiting to do repairs
can be costly and even dangerous.

Electrical System
Electrical System Overload
The vehicle has fuses and circuit breakers to
protect against an electrical system
overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems. Fuses and circuit breakers protect power
devices in the vehicle.
Replace a bad fuse with a new one of the
identical size and rating.
If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible.
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.
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.
