Lighting Features
Entry Lighting

when
Kis pressed on the RKE transmitter.
After about 30 seconds the exterior lamps
turn off. Entry lighting can be disabled
manually by turning the ignition on or to

the remote unlock is pressed, or when the ignition is switched off, all interior lights
turn on and then interior lamps dim to off
within 20 seconds after all doors are closed.
The entry lighting feature for exterior
lighting can be changed. See
“Vehicle
Locator Lights” underVehicle Personalization
0 113.
Exit Lighting
Some exterior lamps come on at night, or in
areas with limited lighting, when the driver
door is opened after the ignition is turned
off. The dome lamp comes on when any
door is opened or after the ignition is
turned off. The exterior lamps and dome
lamp remain on after the door is closed for
a set amount of time, then automatically
turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
The exit lighting for exterior lights can be
changed. See Vehicle Personalization 0113.
Battery Load Management
The vehicle has 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 of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, rear window defogger, climate
control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.

Chevrolet Blazer Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14608203) - 2021 - CRC - 10/29/20
Lighting 127
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 DIC battery voltage and
charging message displays. It is
recommended that the driver reduce the
electrical loads as much as possible. See
Driver Information Center (DIC) (Base and
Midlevel)0107 or
Driver Information Center (DIC) (Uplevel)
0 110.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from draining.
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 off position
and then back to the parking lamp or
headlamp position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
