D

Fuel

Selecting the proper fuel is essential
for satisfactory engine performance.
Engine damage caused by use of improp-
er fuels is not covered under Toyota's new
vehicle warranty.
FUEL TYPE
Use only unleaded 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.
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 unleaded gasoline with a Re-
search Octane Number of 91 or higher
for optimum engine performance.
Use of fuel with an octane number lower
than stated will cause persistent heavy
knocking. If severe, this will lead to en-
gine damage.
If your engine knocks...
If you detect heavy knocking even when
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.
