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.
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Use regular unleaded gasoline with a posted octane
of 87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using 87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
It is recommended that gasoline meet speciﬁcations
which were developed by automobile manufacturers
around the world and contained in the World-Wide Fuel
Charter which is available from the Alliance of Automobile
Manufacturers at www.autoalliance.org/fuel_charter.htm.
Gasoline meeting these speciﬁcations could provide
improved driveability and emission control system
performance compared to other gasoline.
If your vehicle is certiﬁed to meet California Emissions
Standards, it is designed to operate on fuels that meet
California speciﬁcations. See the underhood emission
control label. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
speciﬁcations, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on and your vehicle may fail a smog-check test.
See Malfunction Indicator Lamp on page 3-35.
If this occurs, return to your authorized dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
