Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”

the wrong fasteners, parts can later break
or
fall
off.
You could be hurt.
Adding Equipment to the Outside
of
Your Vehicle
Things
you
might add
to
the outside
of
your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment
to
the outside of
your vehicle.
Fuel
Use premium unleaded gasoline rated at
91
octane or
higher for best performance. You
may
use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well.
At a minimum, the gasoline you use should meet
specifications ASTM
D4814
in
the United States and
CGSB
3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association (AAMA) for
better vehicle performance and engine protection.
Gasolines meeting
the
AAMA
specification could
provide improved driveability and emission control
system protection Fompared to other gasolines.
Be sure the posted octane for premium is at least
9
1
(at least
89
for
middle grade and
87
for regular). If
the octane is less than
87,
you may get a heavy knocking
noise when
you
drive.
If
it’s
bad enough, it can damage
your engine.
If you’re using fuel rated at the recommended octane or
higher and you hear heavy knocking, your engine needs
service. But don’t worry if
you
hear a little pinging
noise when you’re accelerating or driving up a hill.
That’s normal, and
you
don’t have to buy a higher
