2009 CHEVROLET EQUINOX cooling

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 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 gage 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 that
is 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 increaseengine 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 Driver Information Center (DIC)
message might be displayed, such as BATTERY
SAVER ACTIVE, BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical loads
as much as possible. SeeDIC Warnings and Messages
on page 3-49.
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 will
automatically turn the lamp off after 20 minutes. This will
avoid draining the battery. This vehicle also has a
retained accessory power feature. If the radio is on,
it will turn off after 10 minutes or if any door on
the vehicle is opened. SeeRetained Accessory Power
(RAP) on page 2-21.

Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system. For vehicles with the
remote start feature, the climate control system functions
as part of the remote start feature. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5.

9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. To turn the
fan off, turn the fan knob all the way counterclockwise.
In any setting other than off, the fan runs continuously
with the ignition on. The fan must be turned on to run the
air conditioning compressor. There will be some airow
noticeable from the various outlets when driving,
even with the fan in the off position. This is so fresh
air is always available in the vehicle. To turn off
the air completely, turn the fan to
9and select the
recirculation button.
Temperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airow
inside the vehicle.
There is one position between each mode to nely
adjust airow position.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel outlets and the oor outlets.
3-18

6(Floor):Air is directed to the oor outlets with some
air directed to the windshield.
When this mode is selected, the system turns the
recirculation mode off. Recirculation mode cannot be
selected while in oor mode. This helps to prevent
window fogging.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield, side window
outlets, and oor outlets. In this mode, the system
turns the recirculation mode off and runs the air
conditioning compressor unless the outside air is at or
below freezing. Recirculation mode cannot be selected
while in defog mode. This helps prevent window
fogging. To defog the windows faster, turn the
temperature knob clockwise to the warmest setting.
0(Defrost):This mode removes fog or frost from
the windshield more quickly. Air is directed to the
windshield, with some air directed to the side window
outlets and the oor outlets. In this mode, the system
turns the recirculation mode off and runs the air
conditioning compressor unless the outside air is at or
below freezing. Recirculation mode cannot be selected
while in defrost mode. This helps prevent window
fogging. To defrost the windows faster, turn the
temperature knob clockwise to the warmest setting.
For best results, clear all snow and ice from the
windshield before defrosting.
Air Conditioning
#
(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to show
that the air conditioning is on. The air conditioning
can be selected in any mode as long as the fan is on
and the outside temperature is above freezing.
A ashing indicator light indicates that the air
conditioning compressor is currently not available.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days, select the following
settings together:
1. Select
Hmode.
2. Select
;.
3. Turn the
#on.
4. Select the coolest temperature and highest fan
speed.
5. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep the vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes could get so
hot that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let the engine
assist the brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in N (Neutral) or with the ignition
off is dangerous. The brakes will have to do all the
work of slowing down and they could get so hot
that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have the engine running
and the vehicle in gear when going downhill.
Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds
that let you stay in your own lane.
Top of hills: Be alert — something could be in your
lane (stalled car, accident).
Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.
4-16

Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
Start the engine
Shift into a gear
Release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling
a trailer. See this manual’s Maintenance Schedule or
Index for more information. Things that are especially
important in trailer operation are automatic transmission
uid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect
these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-28.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-12
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-15

Automatic Transmission Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid loss.
If a leak occurs, take your vehicle to the dealer/retailer
and have it repaired as soon as possible.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be sure
to use the transmission uid listed inRecommended
Fluids and Lubricants on page 6-11.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-11.
For the 3.6L engine, the transmission uid will not
reach the end of the dipstick unless the transmission
is at operating temperature. If you need to check the
transmission uid level, please take your vehicle to
your dealer/retailer.
Cooling System
The Cooling System allows the engine to maintain the
correct working temperature.
