2012 CHEVROLET SONIC headlamp

Black plate (3,1)Chevrolet Sonic Owner Manual - 2012
Lighting 6-3
The DRL system makes the
low‐beam headlamps come on
at a reduced brightness when the
following conditions are met:
.The ignition is in the ON/
RUN mode.
.The exterior lamps control is
in AUTO.
.The engine is running.
When the DRL are on, only the
low‐beam headlamps, at a reduced
level of brightness, will be on. The
taillamps, sidemarker, instrument
panel, and other lamps will not
be on.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps go off and the DRL
come on. To turn the DRL lamps off or on
again, turn the exterior lamps
control to the off position and then
release. For vehicles first sold in
Canada, the DRL lamps cannot be
turned off.
Automatic Headlamp
System
When it is dark enough outside and
the exterior lamps control is in the
automatic position, the headlamps
come on automatically. See
Exterior
Lamp Controls on page 6‑1.
The vehicle has a light sensor
located on top of the instrument
panel. Make sure it is not covered, or the headlamps will be on when
they are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
Hazard Warning Flashers
|(Hazard Warning Flasher):
Press and momentarily hold this
button located on the instrument
panel above the climate control
system, to make the front and rear
turn signal lamps flash on and off.

This warns others that you are
having trouble. Press and
momentarily hold again to turn the
flashers off.
Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster will flash in the direction of
the turn or lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. The turn signal flashes
three times.The lever returns to its starting
position when it is 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. Replace any
burned out bulbs. If the bulb is not
burned out, check the fuse. See
Fuses and Circuit Breakers on
page 10‑34
orBulb Replacement on
page 10‑29 for more information.
Fog Lamps
For vehicles with front fog lamps,
the button is located on the
outboard side of the instrument
panel. The ignition must be on to turn on
the fog lamps.
#(Fog Lamps):
Press to turn the
fog lamps on or off. An indicator
light on the instrument panel cluster
comes on when the fog lamps
are on.
The fog lamps come on together
with the parking lamps.
If the high‐beam headlamps are
turned on, the fog lamps will turn off.
If the high‐beam headlamps are
turned off, the fog lamps will turn
back on again.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.

Lighting Features
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 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.
Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.

9-10 Driving and Operating
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems”in
the Index.
(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑22.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑57.

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 a dealer for
service.
