CHEVROLET HHR 2010 1.G Owners Manual

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.

Accessory Power Outlet(s)
Accessory power outlets can be used to connect
electrical equipment, such as a cellular phone.
The accessory power outlets are located on the
instrument panel below the climate controls and at the
rear of the center console. There may be an outlet in
the rear cargo area on the passenger side.
To use the outlet, remove the cover. While not in use,
always cover the outlet with the protective cap.
Notice:Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied to
the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment that
exceeds the maximum 20 ampere rating. Certain electrical accessories may not be compatible
with the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power outlet.
Notice:
Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use

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.

15 minutes after the button is pressed. If turned on
again, the defogger only runs for approximately seven
minutes before turning off.
If the vehicle speed is greater than 80 km/h (50 mph)
and the rear defogger is on, it remains on as long as the
speed is greater than 80 km/h (50 mph). The defogger
can also be turned off by turning off the engine.
For vehicles with the remote start feature, the rear
defogger automatically turns on if it is cold outside.
When the vehicle transitions out of the remote start
mode, the rear defogger turns off. SeeRemote Keyless
Entry (RKE) System Operation on page 3‑4
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.Outlet Adjustment
Turn the outlets and move the outlet vanes to change
the direction of the airflow and to open and close the
outlets.
Operation Tips
.Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into the vehicle.
.Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
.Keep the path under the front seats clear of
objects to help circulate the air inside of the vehicle
more effectively.
Passenger Compartment Air Filter
The filter removes dust and pollen from the air which is
drawn into the vehicle. Airflow reduction is an indication
that the filter needs to be replaced.
The filter should be replaced as part of routine
scheduled maintenance. See Scheduled Maintenance
on page 7‑3for replacement intervals. To find out
what type of filter to use, see Maintenance
Replacement Parts on page 7‑12.

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.
