2009 GMC ACADIA oil

TRIP A or TRIP B
Press the trip odometer reset stem
until TRIP A or TRIP B displays.
This display shows the current
distance traveled in either miles (mi)
or kilometers (km) since the last
reset for each trip odometer. Both
trip odometers can be used at
the same time.
Each trip odometer can be reset to
zero separately by pressing and
holding the trip odometer reset stem
while the desired trip odometer is
displayed.
The trip odometer has a feature
called the retro-active reset.
This can be used to set the trip
odometer to the number of miles
(kilometers) driven since the ignition
was last turned on. This can be
used if the trip odometer is not reset
at the beginning of the trip.
To use the retro-active reset feature,
press and hold the trip odometer
reset stem for at least four seconds.
The trip odometer will display the
number of miles (mi) orkilometers (km) driven since the
ignition was last turned on and the
vehicle was moving. Once the
vehicle begins moving, the
trip odometer will accumulate
mileage. For example, if the vehicle
was driven 5 miles (8 km) before
it is started again, and then
the retro-active reset feature is
activated, the display will show
5 miles (8 km). As the vehicle begins
moving, the display will then
increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
If the retro-active reset feature is
activated after the vehicle is started,
but before it begins moving, the
display will show the number
of miles (mi) or kilometers (km) that
were driven during the last ignition
cycle.
OIL LIFE
To access this display, the vehicle
must be in P (Park). Press the
trip odometer reset stem until
OIL LIFE REMAINING displays.This display shows an estimate of
the oil’s remaining useful life. If you
see 99% OIL LIFE REMAINING on
the display, that means 99% of the
current oil life remains. The engine
oil life system will alert you
to change the oil on a schedule
consistent with your driving
conditions.
When the remaining oil life is low,
the CHANGE ENGINE OIL
SOON message will appear on the
display. See “CHANGE ENGINE
OIL SOON” underDIC Warnings
and Messages on page 3-56.
You should change the oil as soon
as you can. SeeEngine Oil on
page 5-11. In addition to the engine
oil life system monitoring the oil
life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Scheduled Maintenance on page 6-3
for more information.
Remember, you must reset the OIL
LIFE display yourself after each oil
change. It will not reset itself. Also,
be careful not to reset the OIL LIFE

system, depending on media
type and format ranges from
5 to 20 seconds for a CD, and up to
30 seconds for a DVD to begin
playing).
If the ignition or radio is turned off,
while a CD is in the player, it stays in
the player. When the ignition or radio
is turned on, the CD starts playing
where it stopped, if it was the last
selected audio source. The CD is
controlled by the buttons on the
radio faceplate or by the RSA unit.
SeeRear Seat Audio (RSA) on
page 3-118for more information.
The DVD/CD decks, (upper slot is
the DVD deck and the lower slot is
the CD deck) of the radio are
compatible with most audio CDs,
CD-R, CD-RW, and MP3/WMAs.
When a CD is inserted, the text label
DVD or CD symbol displays on
the left side of the radio display.
As each new track starts to play,
the track number displays.Care of CDs and DVDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method
of recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD player
scans the bottom surface of the disc.
If the surface of a CD is damaged,
such as cracked, broken, or
scratched, the CD does not play
properly or not at all. Do not touch
the bottom side of a CD while
handling it; this could damage the
surface. Pick up CDs by grasping
the outer edges or the edge of
the hole and the outer edge.
If the surface of a CD is soiled, take
a soft, lint free cloth or dampen a
clean, soft cloth in a mild, neutral
detergent solution mixed with water,and clean it. Make sure the wiping
process starts from the center
to the edge.
Care of the CD and DVD Player
Do not add any label to a CD, it could
get caught in the CD or DVD player.
If a CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the
CD optics with lubricants internal to
the CD and DVD player mechanism.
Notice:If a label is added to
a CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at a
time, and keep the CD player and
the loading slot free of foreign
materials, liquids, and debris.

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy,
nd a safe place to park your
vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
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.
4-12 Driving Your Vehicle

Parking on Hills
{CAUTION
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 at 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 the transmission into
P (Park).
5. Release the brake pedal.
Leaving After Parking
on a Hill
1. Apply and hold the brake pedal
while you:
start the engine,
shift into a gear, and
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.
SeeScheduled Maintenance on
page 6-3for 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.
Trailer Wiring Harness
The vehicle is equipped with the
following wiring harness for towing
a trailer.
