2007 CHEVROLET HHR climate control

Rear Window Wiper/Washer
The rear window
washer/wiper button is
located on the
instrument panel below
the climate controls.
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
5(Delay):Press this side of the button to turn
on the intermittent wiping setting that has a longer
delay.
Y(Washer Fluid):Press this button to wash
and wipe the window.
The rear window washer uses the same uid
bottle as the windshield washer. However, the rear
window washer will run out of uid before the
windshield washer. If you can wash your
windshield but not your rear windows, check the
uid level.
Z(Rear Wiper):Press this side of the button to
turn on an intermittent setting that has a shorter
delay.
To turn either of the intermittent wiper settings off,
press the opposite side of the button to turn it
to the off position. Pressing the button all the way
down on either side will activate an intermittent
wiper setting.

Mirror Reading Lamps
Your vehicle may have reading lamps on the
rearview mirror. Push the button to turn the reading
lamps on and off. The reading lamps will
automatically come on when a door is open.
Rear Reading Lamps
Push the lens to turn the reading lamps on
and off.
Electric Power 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 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 gage 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.
Battery Run-Down Protection
Your vehicle has a battery saver feature designed
to protect your vehicle’s battery.
When any interior lamp is left on and the ignition
is turned off, the battery rundown protection
system will automatically turn the lamp off after
20 minutes. This will avoid draining the battery.

Accessory Power Outlet(s)
Accessory power outlets can be used to connect
electrical equipment such as a cellular phone
or CB radio.
The accessory power outlet is located on the
instrument panel below the climate controls and at
the rear of the center console.
To use the outlet, remove the cover. When 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 for
additional information on the accessory power
outlet.Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the installation instructions included with the
equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

Ashtray(s) and Cigarette Lighter
Your 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 you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has remote start and you want to
warm up or cool down the interior before you
get in, leave your climate control system on with
the settings adjusted where you want them.
The next time the vehicle is started with remote
start, the climate control system will come on and
adjust the interior to the temperature settings.

The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
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.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog or frost from your
windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice
from the windshield before defrosting.
Turn the right knob to select the defog or
defrost mode.
-(Defog):This mode directs approximately half
of the air to the windshield and the side window
outlets and half to the oor outlets. When you
select this mode the system runs the air
conditioning compressor. To defog the windows
faster, turn the temperature control knob clockwise
to the warmest setting.
Recirculation mode is not available in defog mode.
0(Defrost):This mode directs most of the
air to the windshield, with some air directed to the
side window outlets and the oor outlets. When
you select this mode the system runs the air
conditioning compressor. To defrost the windows
faster, turn the temperature control knob
clockwise to the warmest setting.
Recirculation mode is not available in defog mode.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
