Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the vehicle's
propulsion power is reduced. A reduction in
propulsion power can affect the vehicle's
ability to accelerate. If this message is on,
but there is no observed reduction in
performance, proceed to your destination.
Under certain conditions the performance
may be reduced the next time the vehicle is
driven. The vehicle may be driven while this
message is on, but maximum acceleration
and speed may be reduced. Anytime this
message stays on, or displays repeatedly,
the vehicle should be taken to your dealer
for service as soon as possible.

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16547501) - 2023 - CRC - 6/10/22
96 Lighting
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a voltage
display on the Driver Information Center
(DIC), you may see the voltage move up or
down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, rear window
defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idlespeed to generate more power, whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a Driver Information Center
(DIC) message might be displayed, such as
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature helps prevent the battery from
being drained, if the interior courtesy lamps
or reading lamps are accidentally left on.
If any of these lamps are left on, they
automatically turn off after 10 minutes,
if the ignition is off. The lamps will not
come back on again until one of the
following occurs:
.The ignition is turned on.
.The doors are closed and then re-opened.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the vehicle is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the vehicle must be on or in
accessory mode.

occur when things like storms and power
lines interfere with radio reception. When
this happens, try reducing the treble on the
radio.
SiriusXM Satellite Radio Service
If equipped, SiriusXM Satellite Radio Service
provides digital radio reception. Tall
buildings or hills can interfere with satellite
radio signals, causing the sound to fade in
and out. In addition, traveling or standing
under heavy foliage, bridges, garages,
or tunnels may cause loss of the SiriusXM
signal for a period of time. Some cellular
services may interfere with SXM reception
causing loss of signal.
Mobile Device Usage
Mobile device usage, such as making or
receiving calls, charging, or just having the
mobile device on may cause static
interference in the radio. Unplug the mobile
device or turn it off if this happens.
Fixed Mast Antenna
The fixed mast antenna will go through
most car washes as long as it is securely
attached. If the antenna becomes slightly
bent, straighten it out by hand. If it is badly
bent, replace it.Occasionally check that the antenna is tight
at the base. If tightening is required, protect
the paint from damage.
Multi-Band Antenna
The roof antenna may be used for radio,
navigation, and OnStar, depending on the
equipped options. Keep clear of obstructions
for clear reception. If the vehicle has a
sunroof, and it is open, reception can also
be affected.
Audio Players
Avoiding Untrusted Media Devices
When using media devices such as CDs,
DVDs, Blu-ray Discs, SD cards, USB devices,
and mobile devices, consider the source.
Untrusted media devices could contain files
that affect system operation or performance.
Avoid use if the content or origin cannot be
trusted.
Auxiliary Devices
Using the Auxiliary Input Jack
Radios with an auxiliary input jack on the
lower right side can connect to an external
audio device such as an iPod, MP3 player,
or CD player for use as another source for
audio listening. This input jack is not an
audio output; do not plug headphones into
the front auxiliary input jack.
Drivers are encouraged to set up any
auxiliary device while the vehicle is in
P (Park). See
Defensive Driving 0121 for
more information on driver distraction.
To use a portable audio player, connect a
3.5 mm (1/8 in) cable to the radio's front
auxiliary input jack. When a device is
connected, press the radio CD/AUX button
to begin playing audio from the device over
the vehicle speakers.
For optimal sound quality, increase the
portable audio device's volume to the
loudest level.
It is always best to power the portable
audio device through its own battery while
playing.
O: Turn clockwise or counterclockwise to
increase or decrease the volume of the
portable player. Additional volume
adjustments might have to be made from
the portable device if the volume is not loud
or soft enough.
