Scheduled Maintenance Services
Using
Your
Maintenance Schedule
We at General Motors want
to
help you keep your vehicle
in
good working
condition. But we don’t know exactly how
you’ll
drive
it.
You may drive
very short distances
only
a few times a week. Or you may drive long
distances all the time
in
very hot, dusty weather. You may use your vehicle
in
making deliveries. Or
you
may drive
it
to work,
to
do errands or
in
many
other ways.
Because of all the different ways people use their GM vehicles, maintenance
needs vary. You may
even
need more frequent checks and replacements than
you’ll find
in
the schedules
in
this section.
So
please read this section and
note how
you
drive. If
you
have any questions on how
to
keep your vehicle
in
good condition, see your GM dealer.
This part tells you the maintenance services
you
should have done and when
you should schedule them. 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.
The proper fluids and lubricants to use are listed in Part D. Make sure
whoever services your vehicle uses these. All parts should be replaced and
all necessary repairs done before you or anyone else drives the vehicle.
These schedules are
for
vehicles that:
carry passengers and cargo within recommended limits. You will find
these limits on your vehicle’s CertificatiodTire label. See “Loading
Your Vehicle”
in
the Index.
are driven on reasonable road surfaces within legal driving limits.
are driven off-road
in
the
recommended manner. See “Off Road
Driving With Your Four-wheel Drive Vehicle”
in
the
Index.
use the recommended unleaded fuel. See
“Fuel”
in
the Index.
Selecting the Right Schedule
The proper maintenance schedule for your vehicle depends on which engine
you
have
in
your vehicle and how
you
use your vehicle.
Gasoline engine vehicles and diesel engine vehicles have different
maintenance requirements. If you have a diesel engine, follow
a
schedule
designated for diesel engine vehicles
only.
If
you have a gasoline engine,
you must first determine whether your engine has a light duty or a heavy
duty emissions classification. Follow a maintenance schedule designated for
gasoline engines with the emissions classification (light duty or heavy duty)
for your engine. See “Engine Identification”
in
the Index to find your
engine’s emission classification.
