When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See“CHANGE ENGINE OIL SOON”
under Engine Oil Messages on
page 5‑36. You should change the
oil as soon as possible. See Engine
Oil on page 10‑7. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11‑3 for more information.
Remember, you must reset the OIL
LIFE yourself after each oil change.
It will not reset itself. Also, be
careful not to reset the OIL LIFE
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 on page 10‑10. Units
Press

Monitor System (TPMS), the
pressure for each tire can be viewed
in the DIC. The tire pressure will be
shown in either kilopascals (kPa) or
pounds per square inch (psi). Press
Tuntil the DIC displays FRONT
TIRES PSI (kPa) LEFT ##
RIGHT ##. Press
Tagain until the
DIC displays REAR TIRES
PSI (kPa) LEFT ## RIGHT ##. If a low tire pressure condition is
detected by the system while
driving, a message advising you to
check the pressure in a specific tire
will appear in the display. See

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:
.Always 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 on page 10‑10.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

Vehicle Care 10-93
Notice:Avoid using high
pressure washes closer than
30 cm (12 in) to the surface of the
vehicle. Use of power washers
exceeding 8,274 kPa (1,200 psi)
can result in damage or removal
of paint and decals.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
Finish Care
Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces
are damaged, see your dealer to
have the damage assessed and
repaired. Foreign materials such as
calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle's finish if they
remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See
your dealer for approved cleaning
products.
Notice:
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
To keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible. Protecting Exterior Bright Metal
Parts
Regularly clean bright metal parts
with water or chrome polish on
chrome or stainless steel trim,
if necessary.
For aluminum, never use auto or
chrome polish, steam, or caustic
soap to clean. A coating of
wax, rubbed to high polish, is
recommended for all bright metal
parts.
Cleaning Exterior Lamps/
Lenses and Emblems
Use only lukewarm or cold water, a
soft cloth, and a car washing soap
to clean exterior lamps and lenses.
Follow instructions under "Washing
the Vehicle" later in this section.

Black plate (96,1)GMC Savana Owner Manual - 2012 - 2nd - 11/11/11
10-96 Vehicle Care
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild
soap solution, immediately remove
hand lotions, sunscreen, and insect
repellant from all interior surfaces or
permanent damage may result.
Your dealer may have products for
cleaning the interior. Use cleaners
specifically designed for the
surfaces being cleaned to prevent
permanent damage. To prevent
overspray, apply all cleaners directly
to the cleaning cloth. Cleaners
should be removed quickly. Never
allow cleaners to remain on the
surface being cleaned for extended
periods of time.
Cleaners may contain solvents that
can become concentrated in the
interior. Before using cleaners, read
and adhere to all safety instructions
on the label. While cleaning the
interior, maintain adequate
ventilation by opening the doors
and windows.To prevent damage, do not clean
the interior using the following
cleaners or techniques:
.Never use a razor or any other
sharp object to remove a soil
from any interior surface.
.Never use a brush with stiff
bristles.
.Never rub any surface
aggressively or with excessive
pressure.
.Do not use laundry detergents
or dishwashing soaps with
degreasers. For liquid cleaners,
use approximately 20 drops
per 3.78L (1 gal) of water.
A concentrated soap solution will
leave a residue that creates
streaks and attracts dirt. Do not
use solutions that contain strong
or caustic soap.
.Do not heavily saturate the
upholstery when cleaning.
.Do not use solvents or cleaners
containing solvents.
Interior Glass
To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
Commercial glass cleaners may be
used, if necessary, after cleaning
the interior glass with plain water.
Notice:
To prevent scratching,
never use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive cleaning
may damage the rear window
defogger.
