check engine light CHEVROLET TRAIL BLAZER 2009 1.G Owner's Manual

Scheduled Maintenance
When the change engine oil light or CHANGE ENGINE
OIL DIC message displays, service is required for the
vehicle. SeeChange Engine Oil Light on page 3-43or
DIC Warnings and Messages on page 3-51. Have the
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must be
reset. Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km) since
the last service. Remember to reset the oil life system
whenever the oil is changed. SeeEngine Oil Life System
on page 5-22for information on the Engine Oil Life
System and resetting the system.When the change engine oil light or CHANGE ENGINE
OIL DIC message appears, certain services, checks,
and inspections are required. Required services are
described in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended that the
rst service be MaintenanceI, the second service be
MaintenanceII, and then alternate MaintenanceIand
MaintenanceIIthereafter. However, in some cases,
MaintenanceIImay be required more often.
MaintenanceI— Use MaintenanceIif the light or
message displays within 10 months since the vehicle
was purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the light or message displays
10 months or more since the last service or if the
light or message has not come on at all for one year.

(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. Have any torn or frayed safety
belts replaced. Also see Checking the Restraint Systems
on page 1-70.
(f)Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer liftgate handle pivot
points, rear door detent link, roller mechanism, liftgate
handle pivot points, latch bolt, fuel door hinge, cargo door
hinge, locks, and folding seat hardware. More frequent
lubrication may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal better,
and not stick or squeak.
(g)Inspect hoses for cracks, chafing, leaks, kinks, and
proper installation.
(h)Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.(i)Drain, flush, and refill cooling system. This service can
be complex; you should have your dealer/retailer perform
this service. See Engine Coolant on page 5-29 for what to
use. Inspect hoses. Clean radiator, condenser, pressure
cap, and filler neck. Pressure test the cooling system and
pressure cap.
(j)A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k)If driving regularly under dusty conditions, inspect
the filter at each engine oil change.
(l)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
Owner Checks and Services
These owner checks and services should be performed
at the intervals specied to help ensure vehicle safety,
dependability, and emission control performance. Your
dealer/retailer can assist with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to the
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-12.
