GENERAL -Lubrication and Maintenance/Recommended Lubricants and Lubricant Capacities Table00-35
If premium unleaded gasoltne IS not available,
MATERIALS ADDED TO FUEL
unleaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used. Indiscriminate use of fuel system cleaning agents
In this case, the performance and fuel consumption should be avoided. Many of these materials
in-
WIII suffer a little degradatron.tended for gum and varnish removal may contain
highly active
solvents or similar ingredients that can
be harmful to gasket and diaphragm materials used
in fuel system component parts.
Gasolines containing alcohol
Some gasolrnes sold at service stations contain
alcohol, although they may not be SC identified. Use
of fuels containing alcohol is not recommended
unless the nature of the blend can be
determrned
as being satisfactory.
Gasohol
- A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used
In your
car. If
driveability problems are experienced as a
result of using gasohol, it IS recommended that the
car be operated on gasoline. Methanol
- Do not use gasolines containing
methanol (wood alcohol). Use of this type of
alcohol can result in vehicle performance deteriora-
tion and damage critical parts in the fuel system
components. Fuel system damage and performance
problems, resulting from the use of gasolines
containing methanol, may not be covered by the
new car warranty.
Gasolines containing MTBE (Methyl Tertiary Butyl
Ether)
Unleaded gasolrne containrng
15% or less MTBE
may be used in your car. (Fuel containing MTBE
over 15% vol. may cause reduced engine per-
formance and produce vapor lock or hard starting.) RECOMMENDED

SHIFT PATTERNS
Two

shift patterns
are pm-stored
in the
control
‘unit of
this transaxle.
One is the
power
pattern
(for more powerful
performance), and
the
other
is the
economy
pattern
(for
improved

fuel consumption
and quieter
operation).
(Refer to
the

diagram below.)
The
driver
can select
and switch to the
desired
pattern
by
using
the
power/economy
select

switch on the
center
console.
The solid lines
shown
in these
shift patterns
indicate
up-shifts,
and
the
broken lines indicate. down-shifts. The reason why there

is a difference
between
the
shift points for
up-shifts
and for

down-shifts is so that up-shifts
and down-shifts will not
occur frequently
when
driving
at
a speed in the
vicinity of the
shift
point.
When the
vehicle

is stopped,
there
is a shift to -2nd gear
in order
to
obtain
a suitable
“creeping”, but
when the accelerator
pedal is
then
depressed
the
vehicle
starts
off in 1st gear.
