VEHICLE CARE
FUEL SUPPLY
Your vehicle is equipped with a catalytic converter and requires unleaded fuel.
For maximum engine performance, un
leaded fuel with an octaine rating of 91
RON,
which corresponds to an anti-knock
index (AKI) of 87, is recommended.
Do not use leaded gasolines.
Deposits from leaded gasolines deacti
vate the catalytic converter and thus
defeat its purpose to control exhaust emis

sions.

Unleaded fuels may not be available
outside the continental USA and Cana

da.
Therefore, we recommend you do not take your vehicle to areas or coun
tries where unleaded fuel may not be
available. Octane rating
Octane rating indicates a gasoline's ability to
resist detonation. Therefore, buying the cor
rect octane gas is important to prevent en
gine "knock", which reduces performance and may cause engine damage.
Under high load operating conditions, un
leaded premium gasoline may be used.
The 91 RON octane rating which you will find above the filler neck is based on the re search method. The AKI octane rating unsu-
ally displayed on USA gasoline pumps is
calculated as follows: Research octane number plus motor octane number, divided
by 2.
Regular fuels have an octane rating ranging
from 91 to 95 RON (Research Octane Number) or 87 to
91
AKI.
Do not use any fuel with octane ratings
lower than 91 RON or 87 AKI.
Gasolines containing alcohol
Gasoline containing alcohol is available at
gas stations in some areas. The gas pump may not be labeled to identify that alcohol
is present in the gasoline. If it is labeled, it
may not identify what amount and type(s)
of alcohol are used. We recommend you
use quality gasoline that is NOT blended
with alcohol. The use of fuel containing alcohol can cause loss of fuel econorr
and driveability and performance pre:

lems.
If these problems are experience:
we recommend you switch to anothe brand of gasoline.
Seasonally adjusted gasoline
Many gasolines are blended to perfor-
especially well for winter or summer drl
ing.
During seasonal change-over, wl
suggest that you fill up at busy gas statior I
where the seasonal adjustment is mo-r likely to be made in time.
Gasoline additives
A major concern among many aut: manufacturers is carbon deposit build-i:
caused by the type of gasoline you use.
Although gasolines differ from onr manufacturer to another, there is a cor-
mon thread. All gasolines contain props'
ties that can cause deposits to collect ad essential engine components, specificali
fuel injectors and intake valves. Althoug- most gasoline brands include additives tc
keep engine and fuel systems clean, the;,
are not equally effective.
