INFORMATION BEFORE DRIVING YOUR TOYOTA for Your Toyota Prius 4 Door First Generation (1997-2003)

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 To-  
yota has a smaller fuel tank opening. The  
special nozzle on pumps with unleaded fuel  
will fit it, but the larger standard nozzle on  
pumps with leaded gas will not.

300 km (200 miles).  
However, now and then, you may notice  
light knocking for a short time while accel-  
erating or driving up hills. This is no  
cause for concern.  
NOTICE  
GASOLINE CONTAINING DETERGENT  
ADDITIVES  
Do not use leaded gasoline. Use of  
leaded gasoline will cause the three−  
way catalytic converter to lose its  
effectiveness and the emission con-  
trol 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. con-  
tains 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.
