Fuel

FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet specifications of
D4814 in the U.S.A. and CGSB 3.5−M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three−
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.

OCTANE NUMBER
Select Octane Rating 87 (Research Oc-
tane Number 91) or higher.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
ASTM
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
