Engine Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax diesel
supplement.
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 10-8.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10-5 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.

10-16 Vehicle Care
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant recovery tank. If the
coolant inside the coolant recovery
tank is boiling, do not do anything
else until it cools down. If coolant is
visible but the coolant level is not at
or above the COLD FILL mark, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant recovery tank, but be sure
the cooling system is cool before
this is done.
The coolant recovery tank cap has
this symbol on it.When the engine is cold, the coolant
level should be at or above the
COLD FILL mark. If it is not, there
could be a leak in the cooling
system.
If the coolant is low, add the coolant
or take the vehicle to a dealer for
service.
How to Add Coolant to the
Recovery Tank for Gasoline
Engines
{Warning
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
{Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant recovery tank.
How to Add Coolant to the
Radiator
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.

corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon
and attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See“Finish Care”
previously in this section.
Interior Care
To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils. Note
that newspapers or dark garments
that can transfer color to home
furnishings can also permanently
transfer color to the vehicle's
interior.
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
repellent 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. Apply all
cleaners directly to the cleaning
cloth. Do not spray cleaners directly
on any switches or controls.
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
3.8 L (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.

Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and
filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See Engine Oil Life System on
page 10-8.

Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the
following services. See Tire

.Check engine oil level and oil
life percentage. If needed,
change engine oil and filter, and
reset oil life system. See Engine
Oil on page 10-6 andEngine Oil
Life System on page 10-8.
.Check engine coolant level. See
Engine Coolant on page 10-14.
.Check windshield washer fluid
