Speed :Shows the vehicle speed in
either kilometers per hour (km/h) or
miles per hour (mph).
Trip 1 or Trip 2 and Average Fuel
Economy : The Trip display shows the
current distance traveled, in either
kilometers (km) or miles (mi), since
the trip odometer was last reset. The
trip odometer can be reset by pressing
Vand selecting yes or no while this
display is active.
Shows the approximate average liters
per 100 kilometers (L/100 km),
kilometers per liter (km/L), or miles
per gallon (mpg). This number is
calculated based on the number of
L/100 km or km/L recorded since the
last time this menu item was reset.
This number reflects only the
approximate average fuel economy
that the vehicle has right now, and
will change as driving conditions
change. The Average Fuel Economy
can be reset by pressing
Vand
selecting yes or no while this display
is active.
Fuel Range : Shows the approximate
distance the vehicle can be driven
without refueling. LOW will be displayed when the vehicle is low on
fuel. The fuel range estimate is based
on an average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank.
Oil Life :
Shows an estimate of the
oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message
will appear on the display. The oil
should be changed as soon as
possible. See Engine Oil0286. In
addition to the engine oil life system
monitoring the oil life, additional
maintenance is recommended. See
Maintenance Schedule 0358.
The Oil Life display must be reset
after each oil change. It will not reset
itself. Do not reset the Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until the
next oil change. To reset the engine
oil life system, see Engine Oil Life
System 0288. Tire Pressure :
Shows the
approximate pressures of all four tires.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per
square inch (psi). If the pressure is
low, the value for that tire is shown in
amber. See Tire Pressure Monitor
System 0318 and
Tire Pressure Monitor Operation 0319.
Air Filter Life : Shows an estimate of
the engine air filter’s remaining useful
life and the state of the system.
Engine Air Filter Life 95% means 95%
of the current air filter life remains.
Messages will display based on the
engine air filter life and the state of
the system. When the REPLACE AT
NEXT OIL CHANGE message displays,
the engine air filter should be replaced
at the time of the next oil change.
When the REPLACE SOON message
displays, the engine air filter should
be replaced at the earliest
convenience.
The Air Filter Life display must be
reset after the engine air filter
replacement. To reset, see Engine Air
Filter Life System 0289.

CLIMATE CONTROLS 201
Sensor
The solar sensor, on top of the
instrument panel near the windshield,
monitors the solar intensity.
The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.
Air Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airf low.
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.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn 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.
.Do not attach any devices to the air
vent slats. This restricts airf low and
may cause damage to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle. The
filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule0358.
See your dealer regarding replacement
of the filter.

3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or
an extension cord can damage the
cord and may result in overheating
and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault
detection function. An
ungrounded outlet could cause
an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if
needed. Failure to use the
recommended extension cord in
good operating condition,
or using a damaged heater or
extension cord, could make it
(Continued)

To ensure proper engine performance
and long life, careful attention must
be paid to engine oil. Following these
simple, but important steps will help
protect your investment:
.Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil” in
this section.
.Check the engine oil level regularly
and maintain the proper oil level.
See “Checking Engine Oil” and
“When to Add Engine Oil” in this
section.
.Change the engine oil at the
appropriate time. See Engine Oil Life
System 0288.
.Always dispose of engine oil
properly. See “What to Do with Used
Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick handle is a loop. See
Engine
Compartment Overview 0285 for the
location.
{Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the
engine oil level after the engine has
been off for at least two hours.
Checking the engine oil level on
steep grades or too soon after
engine shutoff can result in
incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove the
dipstick and check the level.
.If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
or at least 30 minutes if the engine

low, the CHANGE ENGINE OIL
SOON message will appear on the
display.
2. Press
Von the DIC controls and
hold down for a few seconds to
clear the CHANGE ENGINE OIL
SOON message and reset the oil life
at 100%.
Be careful not to reset the oil life
display accidentally at any time
other than after the oil is changed.
It cannot be reset accurately until
the next oil change.
The system is reset when the
CHANGE ENGINE OIL SOON message
is off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat the
procedure.
Automatic Transmission
Fluid
A transmission fluid leak is the only
reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and
have it repaired as soon as possible.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty.
Always use the correct automatic
transmission fluid. See
Recommended Fluids and Lubricants
0 367.
See your dealer to have the fluid and
filter changed at the intervals listed in
the Maintenance Schedule 0358.
Engine Air Filter Life
System
If equipped, this feature provides the
engine air filter's remaining life and
best timing for a change. The timing to change an engine air filter depends
on driving and environmental
conditions.
When to Change Engine Air
Filter
When the Driver Information Center
(DIC) displays a message to replace
the engine air filter at the next oil
change, follow this timing.
When the DIC displays a message to
replace the engine air filter soon,
replace the engine air filter at the
earliest convenience. The system must
be reset after the engine air filter is
changed.
If the DIC displays a message to check
the engine air filter system, see your
dealer.
How to Reset Engine Air Filter

housing.
2. Lift the air cleaner/filter cover housing away from the engine.
3. Pull out the filter.
{Warning
If part replacement is necessary,
the part must be replaced with one
of the same part number or with an
equivalent part. Use of a
replacement part without the same
fit, form, and function may result in
personal injury or damage to the
vehicle.
