minimum Posted Octane Rating of 91 (average
of 96 RON/86 MON). Information on gasoline
quality can normally be found on the fuel
pump. Please contact gas station personnel in
case labels on the pump cannot be found.

"Premium unleaded gasoline" (

page 306),
see "Fuel requirements" (

page 306), and

Premium unleaded gasoline
!
To maintain the engine’s durability and
performance, premium unleaded gasoline
must be used. If premium unleaded gasoline is
not available and low octane fuel is used,
follow these precautions:
• Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.
• Avoid full throttle driving and abrupt
acceleration.
• Do not exceed an engine speed of 3 000 rpm
if the vehicle is loaded with a light load such
as two persons and no cargo.
•Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded
or operating in mountainous terrain.
Fuel requirementsOnly use premium unleaded fuel:
• The octane number (posted at the pump)
must be 91 min.
It is an average of both the R
esearch
O
ctane N
umber (RON) and the M
otor O
ctane
N
umber (MON): (RON+MON) /2. This is also
known as the ANTI
KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be used
provided the ratio of any one of these
oxygenates to gasoline does not exceed 10%;
MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is not
allowed. Gasohol, which contains 10% ethanol
and 90% unleaded gasoline, can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
G
Warning!
Gasoline is highly flammable and poison

ous. It burns violently and can cause
serious personal injury.
Never allow sparks, flame or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin or clothing
contact, extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to
your health.
