When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be
a problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition
cycle. SeeTire Pressure Monitor
Operation on page 10‑56 for more
information.
Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
(Continued)
WARNING (Continued)
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine
oil maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
goes off.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and it might
have some other system problem.
Security Light
For information regarding this light
and the vehicle's security system,
see Anti-theft Alarm System on
page 2‑9.
High-Beam On Light
This light comes on when the
high-beam headlamps are in use.

Exterior Lamps Off
Reminder
If a door is open, a reminder chime
sounds when the headlamps or
parking lamps are manually turned
on and the key is out of the ignition.
To turn off the chime, turn the
headlamp switch to off and then
back on. In the automatic mode, the
headlamps turn off once the ignition
is in LOCK/OFF.
For vehicles first sold in Canada,
if the parking lamps are turned on
manually, the Daytime Running
Lamps (DRL) will stay on.
Headlamp High/
Low-Beam Changer
2 3
Headlamp High/Low Beam
Changer: Push the turn signal/
multifunction lever away from you
to turn the high beams on.
Pull the lever towards you to return
to low beams.
This indicator light turns on in the
instrument panel cluster when the
high beam headlamps are on.
Flash-to-Pass
This feature lets you use the
high-beam headlamps to signal
a driver in front of you that you
want to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low
beam, the high-beam headlamps
will turn on. They will stay on as
long as the lever is held toward you. The high-beam indicator on the
instrument panel cluster will come
on. Release the lever to return to
normal operation.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system will come on when
the following conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The transmission is not in
P (Park) if you have an
automatic transmission.
.The light sensor determines it is
daytime.

Black plate (3,1)Chevrolet Colorado Owner Manual - 2012
Lighting 6-3
When the DRL are on, only the
parking lamps or reduced intensity
low beam headlamps will be on.
The taillamps, sidemarkers, and
other lamps will not be on. The
instrument panel will not be lit up
either.
When it begins to get dark, the
headlamps will automatically switch
from DRL to the regular headlamps.
The regular headlamp system
should be turned on when needed.
Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrumentpanel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a
parking garage, through a tunnel or
when there is overcast weather.
This is normal.
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 will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it will take about 1 minute for the
automatic headlamp system to
change to DRL if it is light outside.
During that delay, the instrument
panel 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 Control on
page 6‑6.

Fog Lamps
The fog lamp button is located near
the exterior lamps control.
#:For vehicles with fog lamps,
press to turn the fog lamps on or off.
An indicator light will turn on in the
button when the fog lamps are on.
The parking lamps or low‐beam
headlamps must be on for the fog
lamps to work. The fog lamps will
go off whenever the high-beam
headlamps come on. When the high
beams go off, the fog lamps come
on again. Some localities have laws that
require the headlamps to be on
along with the fog lamps.
Exterior Cargo Lamps
The cargo lamps (if equipped) can
be used if more light is needed in
the cargo area of the vehicle or in
the top-box storage units.
This button is located on the driver
side of the instrument panel near
the exterior lamp control.Press to turn the cargo lamps on
and off.
The dome lamps must be on for the
cargo lamps to come on. See
Dome
Lamps on page 6‑6.
If the vehicle is equipped with
Bluetooth
®, turning the instrument
panel illumination control
thumbwheel all the way up will
turn on the cargo lamps.

Exit Lighting
The interior lamps will come on
when the key is removed from the
ignition. The lamps will not come
on if the dome override button is
pressed in.
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 thevoltage 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,
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 DIC message
might be displayed, such as
BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW
BATTERY. If one of these messages
displays, it is recommended that the
driver reduce the electrical loads as
much as possible. See
Driver
Information Center (DIC) on
page 5‑19.
Battery Power Protection
This feature shuts off the dome
lamp if it is left on for more than
20 minutes when the ignition is in
LOCK/OFF. This helps to prevent
the battery from running down.

Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer
for service.
