Tf you are skilled enough to do some work on your vehicle, you will
probably want to get the service information
GM publishes. For information
on how
to obtain various service publications for your vehicle, see “Service
Publications”
in the Index. You will find a list of publications and an order
form
in the back of the book.
Scheduled Maintenance Services
This part tells you the maintenance services that you should have done and
the times you should schedule them. Your
GM dealer knows your vehicle
best and wants you to be happy with
it. If you go to your dealer for your
service needs, you’ll know that GM-trained and supported service people
will perform the work using genuine
GM parts.
These schedules are for vehicles that:
0 carry passengers and cargo within the recommended limits. You will
find these limits on your vehicle’s Certification Label. See “Loading
Your Vehicle’’ in the Index.
are driven on regular road surfaces, and within legal driving limits, as
described in Section 4 “Your Driving and the Road.”
0 are driven off-road in the recommended manner. See “Off Road
Driving With Your Four-wheel Drive Vehicle”
in the Index.
0 use the recommended fuel. See “Fuel” in the Index.
Selecting the Proper Maintenance Services
To find the proper maintenance schedule for your vehicle, you must know
two things. What engine your vehicle has, and how you
use your vehicle.
Your engine type will tell
you which chart to use, and your driving
conditions will tell
you which schedule to use. ’The charts are found later in
this section.
Selecting the Proper Maintenance Chart
Your engine type (Gasoline or Diesel) and its emissions classification (Light
Duty or Heavy Duty Emissions) will
tell you which maintenance chart to
use. Find your Vehicle Identification Number (VIN), and look at the eighth
character
to see what your engine code is. Then use the following Engine
Emissions Classifications tables
to find your emissions classification.
Your VIN is on the plate on the top left corner of your instrument
panel, the Certification Label and on the Service Parts Identification
Label. See “Vehicle Identification Number’’
in the Tndex.
If your engine has more than one emissions classification, look at your
Certification Label to see what your Gross Vehicle Weight Rating
(GVWR)
is. See “Loading Your Vehicle” in the Index.
