2012 CHEVROLET MALIBU cooling

Black plate (7,1)Chevrolet Malibu Owner Manual - 2012
Lighting 6-7
This is because the generator
(alternator) may not be spinning
fast enough at idle to produce all of
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. If so, a DIC message might
be displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑24.
Battery Power Protection
The vehicle has a battery run-down
protection feature designed to
protect the vehicle's battery.
When any interior lamp (trunk,
reading, or visor vanity) is left on
while the ignition is turned off, the
battery run-down protection system
will automatically shut the lamp(s)
off after 20 minutes. This will avoid
draining the battery. To reactivate the interior lamps,
do one of the following:
.Turn on the ignition.
.Turn the exterior lamp control off
and then on.
.Open a door.
.Press any Remote Keyless
Entry (RKE) transmitter button
(if equipped).
.Press the remote trunk release
button.
.Press the power door lock
switch.
The battery run-down feature will
also be activated when any door
on the vehicle is left open and the
ignition is in LOCK/OFF.

Automatic Operation
AUTO (Automatic):
Select AUTO
on both the fan speed control and
the air delivery mode control knobs
to activate the automatic system.
When automatic operation is active
the system controls the inside
temperature and air delivery.
To place the system in automatic
mode do the following:
1. Turn the fan knob and the mode knob to the AUTO position.
The current set temperature
displays. When AUTO is
selected, the air conditioning
operation and air inlet is
automatically controlled. The air
conditioning compressor runs
while the outside temperature is
over about 40°F (4°C). The air
inlet will normally be set to
outside air. If it is hot outside,
the air inlet may automatically
switch to recirculate inside air to
help quickly cool down the
vehicle.

2. Set the temperature.An initial setting of 73°F (23°C)
is recommended. Allow about
20 minutes for the system to
regulate. Press
worxto
adjust the temperature setting as
necessary. If the temperature is
set at 60°F (15°C) the system
remains at the maximum cooling
setting. If the temperature is set
at 90°F (32°C) the system
remains at the maximum heat
setting. Choosing either
maximum setting does not
cause the vehicle to heat or
cool any faster.
Do not to cover the sensor
located on the top of the
instrument panel near the
windshield. This sensor
regulates air temperature based
on the intensity of the sun. Also do not cover the sensor
grille on the lower right side of
the climate control faceplate,
as this regulates the inside
temperature.
To avoid blowing cold air at
engine start-up in cold weather,
the system delays turning on the
fan until warm air is available.
The length of delay depends on
the engine coolant temperature.
Turning the fan knob overrides
this delay and changes the fan
to the selected speed.
Manual Operation
o(Off):
Select this position on the
fan knob to turn off the entire
climate control system. Outside air
still enters the vehicle. The airflow
direction and temperature can be
adjusted.
x/wTemperature Control:
Press the arrows to increase or
decrease the temperature inside the
vehicle.
9(Fan Control): Turn clockwise
or counterclockwise to increase or
decrease the fan speed.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the direction of the airflow in
the vehicle.

9-8 Driving and Operating
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
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.
{WARNING
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.
.Be alert on top of hills,
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.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.

Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet.
Turn the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. 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 fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. 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. See Engine Overheating
on page 10‑20.
