Be sure you have suffkient 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”
fasteners can be easily confused.
If
you use
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 udeaded 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 compared to other gasolines.
Be sure the posted octane for premium is at 1,east 91 (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
bqd
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
