Break−in period  
Fuel  
Drive gently and avoid high speeds.  
FUEL TYPE  
Use of unleaded fuel with an octane num-  
ber or rating lower than stated above will  
cause persistent heavy knocking. If se-  
vere, this will lead to engine damage.  
Your vehicle must use only unleaded  
gasoline.  
Your vehicle does not need an elaborate  
breakin. But following a few simple tips  
for the first 1000 km (600 miles) can add  
to the future economy and long life of  
your vehicle:  
To help prevent gas station mixups, your  
Toyota has a smaller fuel tank opening.

leaded fuel will fit it, but the larger stan-  
dard nozzle on pumps with leaded gas will

300 km (200 miles).  
NOTICE  
GASOLINE CONTAINING DETERGENT  
ADDITIVES  
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.  
Toyota recommends the use of gasoline  
that contains detergent additives to  
avoid build−up of engine deposits.  
However, all gasoline sold in the U.S.  
contains detergent additives to keep clean  
and/or clean intake systems.  
OCTANE RATING  
Select unleaded gasoline with an Oc-  
tane Rating of 87 (Research Octane  
Number 91) or higher.
