2. Just prior to reaching the maximum engine speed, quickly complete the upshift utilizing the clutch
while keeping the accelerator pedal fully applied.
A quicker shift maneuver gives the best
performance. If the engine is operated at the
maximum engine speed for greater than
one second, the engine exits the No‐Lift Upshift
mode and resumes normal engine overspeed
protection.Parking Brake
The parking brake lever is located between the front
seats.

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.

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
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear): Press to turn the rear window defogger on
or off. Be sure to clear as much snow from the rear
window as possible. An indicator light comes on to
show that the rear window defogger is on.
4-20

The rear window defogger turns off approximately
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.
