Break-in Period
Help assure your car's future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:
Avoid full-throttle starts and rapid
acceleration.
Avoid hard braking. New brakes
need to be broken-in by moderate
use for the first 200 miles (300
km).
You should follow these same re-
commendations with an overhauled
or exchanged engine, or when the
brakes are relined.
Before Driving
Table of Contents
Gasoline
Your Honda is designed to operate
on unleaded gasoline.
We recommend gasolines containing
detergent additives that help prevent
fuel system and engine deposits.
Using gasoline containing lead will
damage your car's emission controls.
This contributes to air pollution.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emission control system
performance may deteriorate and
the malfunction indicator lamp on
your instrument panel may turn on.
If this happens, contact your
authorized Honda dealer for service.
(S and Si models)
Use an unleaded gasoline with a
pump octane number of 86 or higher.
Use of a lower octane gasoline can
cause a persistent, heavy metallic
rapping noise in the engine that can
lead to mechanical damage.
(VTEC model)
Use a premium unleaded gasoline
with a pump octane number of 91 or
higher.
If you are unable to find premium
unleaded gasoline, you may substi-
tute an unleaded regular gasoline.
The engine will compensate for the
lower octane, but you may notice a
slight decrease in power as a result.
Oxygenated Fuels
Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines
are collectively referred to as
oxygenated fuels. To meet clean air
standards, some areas of the United
States and Canada use oxygenated
fuels to help reduce emissions.
