light CHEVROLET HHR 2010 1.G Service Manual

When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If the drivers door is opened with the ignition off and the
lamps on, a warning chime will sound. This indicates
that the headlamps are still on.
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 vehicle has a light sensor on top of the instrument
panel. Do not cover this sensor or the headlamps will
come on when they are not needed.
The DRL system will make the headlamps come on at
reduced brightness when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is turned to AUTO.
.The light sensor detects daytime light.
.The shift lever is not in P (Park).While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be on.
For vehicles with an Automatic Transmission, the DRL
system is off any time the vehicle is in P (Park). For
vehicles with a Manual Transmission, the DRL system
will be off when the vehicle is first started, the park
brake is applied, and the vehicle has not moved. The
DRL system on U.S. vehicles can also be turned off by
using the off/on switch for one ignition cycle.
The regular headlamp system should be turned on
when needed.
Automatic Headlamp System
When it is dark enough outside, the automatic system
turns on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior
switch backlighting.
Do not cover the light sensor, located on top of the
instrument panel. If the sensor is covered the
headlamps may remain on when they are not needed.
If the vehicle is driven through a parking garage,
overcast weather or a tunnel, the automatic headlamp
system may turn on.
4-12

There is a delay in the transition between the daytime
and nighttime operation of the automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the light
sensor sees a change in lighting lasting longer than
this delay.
If the vehicle is started in a dark garage, the automatic
lamp system turns on immediately. Once the vehicle
exits the garage, it will take about 20 seconds for the
automatic lamp 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. SeeInstrument Panel Brightness
on
page 4‑14.
To idle the vehicle with the system off, turn the ignition
on and turn the exterior light switch to the off/on
position. For vehicles first sold in Canada, the
transmission must stay in P (Park) for this function
or the parking brake must be set for vehicles with
manual transmissions.
Turn on the regular headlamps when they are needed.
Fog Lamps
For vehicles with fog lamps, the button is located on the
instrument panel, to the right of the steering wheel.
The ignition must be on to use the fog lamps.
#: Press to turn the fog lamps on and off. An indicator
light on the button comes on when the fog lamps
are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Instrument Panel Brightness
The control for this feature
is located to the right of
the steering wheel and
above the radio.
Move the thumbwheel to the left to dim the lights or to
the right to brighten the lights.
The dome lamps will turn on when the thumbwheel is
moved completely to the right.
Dome Lamp
The dome lamps turn on when any door is opened.
To turn on all dome lamps with the doors closed, turn
the instrument panel brightness thumbwheel completely
to the right. See Instrument Panel Brightness
on
page 4‑14.
Entry/Exit Lighting
The lamps inside the vehicle turn on when any door
is opened. These lamps will fade out after about
20 seconds after all of the doors have been closed or
when the ignition is turned to ON/RUN. These lamps
will also turn on when pressing the unlock symbol
button or the horn symbol on the keyless entry system
transmitter.
The lamps inside the vehicle will stay on for about
20 seconds after the key is removed from the ignition
to provide an illuminated exit.
Reading Lamps
There are reading lamps located on the front and rear
dome lamps.
To turn the front reading lamps on or off, press the lamp
lens. To turn the rear reading lamps on or off, press the
button next to the lamp.

Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery's
temperature and state of charge and 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 put the charge back in. When
the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or 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 loads are on: 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 Run-Down Protection
The vehicle has a battery saver feature designed to
protect the vehicle's battery.
When any interior lamp is left on and the ignition is
turned off, the battery rundown protection system
automatically turns the lamp off after 20 minutes.
This prevents draining of the battery.

Ashtray(s) and Cigarette Lighter
The vehicle may have an ashtray and cigarette lighter.
To use the lighter, located on the instrument panel
below the climate controls, push it in all the way and
let go. When it is ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not use
equipment exceeding maximum amperage rating
of 15 amperes.
To clean the center console ashtray, remove the entire
ashtray and empty it.
Notice: If papers, pins, or other flammable items are
put in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
the vehicle. Never put flammable items in the
ashtray.

For quick cool down on hot days:1. Select
H.
2. Select
@.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
can cause the air inside of the vehicle to become too
dry. To prevent this from happening, after the air in the
vehicle has cooled, turn off the recirculation by pressing
the outside air button.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This
is normal.
The air conditioning compressor cannot be turned on
when the fan is off.
@(Recirculation): Press to turn the recirculation
mode on. An indicator light comes on to show that
recirculation is on. This mode recirculates and helps to quickly cool the
air inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
The air conditioning compressor also comes on.
Recirculation is not available in floor, defog and defrost
modes. If the recirculation button is pressed, the
indicator light flashes five times and outside air is
delivered. Operation in this mode during periods of high
humidity and cool outside temperatures can result in
increased window fogging. If window fogging is
experienced, select the defrost mode.
;(Outside Air):
Press to allow outside air to circulate
through the vehicle. An indicator light comes on to show
that outside air is on.
Rear Window Defogger

Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there is
a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2‑60.
The airbag readiness
light flashes for a few
seconds when the engine
is started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
