Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system comes on in
daylight when the following
conditions are met:
.The ignition is on.
. The exterior lamp control is in
the AUTO position.
. The shift lever is not in P (Park).
. The light sensor determines it is
daytime.
When the DRL are on, the taillamps,
sidemarker, instrument panel lights,
and other lamps will not be on.
The automatic headlamp system
automatically switches from DRL to
the headlamps depending on the
darkness of the surroundings. To turn off the DRL, turn the exterior
lamp control to
Oand then release
it. For vehicles first sold in Canada,
the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps, along with
the taillamps, sidemarker lamps,
parking lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamp
control to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.The vehicle has a light sensor on
the top of the instrument panel. Do
not cover the sensor; otherwise the
system will come on whenever the
ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system are only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.

128 Lighting
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately 30 seconds
for the automatic headlamp system
to change to DRL if it is light
outside. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control0129.
To idle the vehicle with the
automatic headlamp system off, turn
the control off.
The headlamps will also stay on
after exiting the vehicle. This feature
may be programmable. See Vehicle
Personalization 0120.
If the feature is not programmable,
exit lighting is automatic. When it is
dark enough outside, the exterior
lamps remain on for 30 seconds
after the ignition is turned off.Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P
or;to disable this feature.
Hazard Warning Flashers

not work.
Turn and Lane-Change
Signals
G: An arrow on the instrument
cluster flashes in the direction of the
turn or lane change.
To signal a turn, move the lever all
the way up or down.

Lighting 129
and if the Tow/Haul Mode is active it
flashes six times. Holding the turn
signal lever for more than
one second causes the turn signals
to flash continually until the lever is
released.
The lever returns to its starting
position when released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If a bulb is not burned out,
check the fuse. SeeFuses and
Circuit Breakers 0264.
Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 mi), a chime
sounds at each flash of the turn
signal and the message TURN

Lighting Features
Entry Lighting
If it is dark enough outside, the
exterior lamps will turn on briefly
when unlocking the vehicle with the
RKE transmitter.
Entry/Exit Lighting
The vehicle has an illuminated
entry/exit feature.
The dome lamps come on if the
E
DOME OFF button is in the

opened, or the key is removed from
the ignition.
Exit Lighting
If it is dark enough outside, the
exterior lamps will turn on when the
ignition is turned off. This feature
may be programmable. See Vehicle
Personalization 0120.
Battery Load
Management
The vehicle may have Electric
Power Management (EPM) that
estimates the battery's temperature
and state of charge. It then adjusts
the voltage for best performance
and extended life of the battery.
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.

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12146162) - 2019 - crc - 11/26/18
Lighting 131
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 idle speed 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 isrecommended that the driver reduce
the electrical loads as much as
possible.
Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
off. This helps to prevent the battery
from running down.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition 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 ignition must be on
or in ACC/ACCESSORY.
