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 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 Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE or BATTERY
VOLTS LOW. If this message is
displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC)
on
page 5‑27.
Battery Power Protection
This feature helps to prevent battery
drain if accessory lamps are left on.
If accessory lamps such as the
vanity mirror, cargo, reading,
console, or glove box are left on,
they automatically time-out after
about 20 minutes. To reset the
battery protection, all of the above
lamps must be turned off or the
ignition must be in the ACC/
ACCESSORY position.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned to LOCK/OFF, if the parking
lamps or headlamps have been left
on. This protects against draining
the battery. The battery saver does
not work if the headlamps are
turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than
10 minutes, turn the lamps back on
with the exterior lamp control.

If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
might need to be replaced. For more
information, seePassenger
Compartment Air Filter
on
page 8‑6and Scheduled
Maintenance on page 11‑3.
H G(Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[(Floor):
Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor, and
side window outlets. When this
mode is selected, the system turns
off recirculation and runs the
air-conditioning compressor unless
the outside temperature is at or
below freezing. If recirculation is
selected while in defog mode, it is
cancelled after 10 minutes.
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some air directed to
the side windows. In this mode, the
system automatically turns off
recirculation and runs the air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
#(Air Conditioning):
Press to
turn the air conditioning system on
or off and override the automatic
system. When in AUTO, the air
conditioning compressor comes on
automatically, as needed.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
M(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated inside
the vehicle. It helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Press the AUTO button to have the
system select the best air delivery
mode for the temperature setting.

Recirculation is not available in the
defrost mode and automatically
turns off 10 minutes after defog is
selected. This helps to limit window
fogging in the vehicle.
Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry or
stuffy. To prevent this from
happening, after the air in the
vehicle has cooled, select outside
air or press the auto button.
F(Outside Air):Press to turn
on the outside air. An indicator light
turns on. The outside air mode pulls
fresh air from outside the vehicle.
Outside air is always selected in
defrost mode to prevent fogging.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or frost
from the rear window. It only works
when the ignition is in ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger stays on
for about 15 minutes, before turning
off if the vehicle is moving at a
slower speed. At higher speeds, the
rear window defogger may stay on
continuously. With each additional
press, the defogger runs for about
10 minutes. The defogger can also
be turned off by turning off the
engine.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and helps to
clear fog or frost from the surface of
the mirrors. See Heated Mirrors
on
page 2‑27.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your radio's ability to pick up stations
clearly. The repairs wouldn't be
covered by your warranty.
z/{(Heated and Ventilated
Seats): Press to heat or ventilate
the seat. See Heated and Ventilated
Front Seats on page 3‑12.
Remote Start Climate Control
Operation: For vehicles with
remote vehicle start, the climate
control system automatically heats
and cools the vehicle based on the
temperature inside and outside of
the vehicle. The climate control
displays will be blank. See Remote
Vehicle Start on page 2‑11.
In cold weather the windshield
defroster and/or rear window
defogger automatically turn on.
If the vehicle has heated seats, they
will also turn on.
When the ignition is turned to ON/
RUN, the climate control system
returns to the settings used before
the vehicle was last turned off. The
heated seats will turn off,
if equipped.

Under certain conditions, the air
quality sensor will not activate
recirculation, such as during cold
weather or with odors, like skunk. To
limit odors manually, press
Muntil
the condition has passed.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust
on
page 9‑24.
Air Vents
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airflow. Use the thumbwheels near
the air outlets to open or close off
the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter traps most of the dust and
pollen from the air entering the
vehicle. The filter will need to be
changed periodically. See
Scheduled Maintenance
on
page 11‑3.
Using the climate control system
without the passenger air filter
installed could let water or other
debris enter the system. This could
cause a water leak or noises. Make
sure a new air filter is installed after
removing the old one.

9-4 Driving and Operating
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts—heavy acceleration
followed by heavy braking —rather
than keeping pace with traffic. This
is a mistake. The brakes might not
have time to cool between hard
stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer accessories can
affect vehicle performance. See
Accessories and Modifications
on
page 10‑4.
Steering
Power Steering
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Speed Variable Assist Steering
The vehicle has a steering system
that varies the amount of effort
required to steer the vehicle in
relation to the speed of the vehicle. The amount of steering effort
required is less at slower speeds
to make the vehicle more
maneuverable and easier to park. At
faster speeds, the steering effort
increases to provide a sport-like feel
to the steering. This provides
maximum control and stability.
If the vehicle seems harder to steer
than normal when parking or driving
slowly, there may be a problem with
the system. You will still have power
steering, but steering will be stiffer
than normal at slow speeds. See
your dealer for service.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
