2007 CHEVROLET TAHOE low oil pressure

Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be
cleared. You should take any messages that
appear on the display seriously and remember that
clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs
to be changed. When you change the engine
oil, be sure to reset the CHANGE ENGINE OIL
SOON message. SeeEngine Oil Life System
on page 462for information on how to reset the
message. This message clears itself after
10 seconds until the next ignition cycle or until the
message is reset. SeeEngine Oil on page 459
andScheduled Maintenance on page 579for more
information.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the
pressure in one or more of the vehicle’s tires need
to be checked. This message also displays
LEFT FRONT, RIGHT FRONT, LEFT REAR, or
RIGHT REAR to indicate which tire needs to
be checked. You can receive more than one tire
pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button or the trip
odometer reset stem. If a tire pressure message
appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label.
SeeTires on page 507,Loading Your Vehicle on
page 407, andInation - Tire Pressure on
page 515. The DIC display also shows the tire
pressure values for the front and rear tires
by pressing the vehicle information button. See
“DIC Operation and Displays (With DIC Buttons)”
earlier in this section. If the tire pressure is
low, the low tire pressure warning light comes on.
SeeTire Pressure Light on page 253.

This message displays and a chime sounds if the
driver’s side rear door is not fully closed and
the vehicle is in a drive gear. Stop and turn off the
vehicle, check the door for obstructions, and
close the door again. Check to see if the message
still appears on the DIC.
OIL PRESSURE LOW STOP ENGINE
Notice:If you drive your vehicle while
the engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the Driver Information
Center (DIC), stop the vehicle as soon as
possible. Do not drive the vehicle until the
cause of the low oil pressure is corrected. See
Engine Oil on page 459for more information.
This message displays if low oil pressure
levels occur. Stop the vehicle as soon as safely
possible and do not operate it until the cause
of the low oil pressure has been corrected. Check
the oil as soon as possible and have your
vehicle serviced by your dealer. SeeEngine Oil on
page 459.

If no coolant is visible in the surge tank, add
coolant as follows:
{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 coolant surge tank pressure
cap — even a little — they can come out at
high speed. Never turn the cap when the
cooling system, including the coolant
surge tank pressure cap, is hot. Wait for
the cooling system and coolant surge
tank pressure cap to cool if you ever have
to turn the pressure cap.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.

Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.
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.
