low oil pressure GMC ACADIA 2008 Owner's Manual

For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional 10 minutes are considered a second
remote start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key.
After the key is removed from the ignition, the vehicle
can be started using the remote start feature again.
The vehicle cannot be started using the remote
start feature if the key is in the ignition, the hood is not
closed, or if there is an emission control system
malfunction.
Also, the engine will turn off during a remote start if the
coolant temperature gets too high or if the oil pressure
gets low.Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle
start system enabled. The system may be enabled or
disabled through the DIC if your vehicle has DIC
buttons. See “REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 3-75
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or
disable the remote start system.
Remote Start Ready
If your vehicle does not have the remote start feature, it
will have the remote start ready feature. This feature
allows your dealer/retailer to add the manufacturer’s
remote start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote start feature to your vehicle.

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 3-66. You should change the
oil as soon as you can. SeeEngine Oil on page 5-15.

{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer and
other uids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the hood release
handle with this symbol
on it. It is located
under the instrument
panel on the driver’s
side of the vehicle.2. At the front of the vehicle, pull up on the center of
the hood, and push the secondary hood release to

3. After you have partially lifted the hood, gas struts
will automatically take over to lift and hold the
hood in the fully open position.
Before closing the hood, be sure all ller caps are on
properly.
Pull the hood down to close. Lower the hood until the
lifting pressure of the strut is reduced. Then allow
the hood to fall and latch into place under its own
weight. Check to make sure the hood is closed. If the
hood does not fully latch, gently push the hood down at
the front and center of the hood until it is completely
latched.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-14for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have
to turn the pressure cap.
{CAUTION:
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle’s
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The
engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
5-29

Do not clean your vehicle using the following cleaners
or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure
can damage your interior and does not improve the
effectiveness of soil removal.
Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers.
Using too much soap will leave a residue that
leaves streaks and attracts dirt. For liquid cleaners,
about 20 drops per gallon (3.78 L) of water is a
good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result from
the use of many organic solvents such as naptha,
alcohol, etc.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on oor carpet and carpeted oor mats. For soils, always
try to remove them rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.
